Answer:

Intercepts at (-1, 0) and (0, 1).

Step-by-step explanation:

The double intercept form for the equation of a line is

ax + by = 1

-1 = -y + x

y = 0

x = -1     Multiply each side by -1

-x = 1

The x-intercept is at (-1, 0).

=====

x = 0

-1 = -y     Multiply each side by -1

y = 1

The y-intercept is at (0, 1).

=====

The graph (see below) is a straight line passing through the points (-1, 0) and (0, 1).

Additive inverse is what you add to a number to get zero.

So, by definition, the additive inverse of (-8 + 3i) would be (8 - 3i).

Erica made errors by failing to borrow 1 hour when subtracting the hours and misrepresenting the final duration of the school day as 5 hours and 25 minutes instead of the correct 6 hours and 45 minutes.

Erica's calculation:

7hr   65

8 hr 5 min -

2hr 40 min

---------------

5hr 25 minutes

1. **Subtraction of minutes:**

  Erica correctly subtracted the minutes: 5 minutes - 40 minutes = 25 minutes.

2. **Subtraction of hours:**

  Here's where the error lies. Erica attempted to subtract the hours directly without borrowing. Let's correct this step:  

  Borrow 1 hour from the 7 hours:

  [tex]\[7 \text{ hours} - 1 \text{ hour} = 6 \text{ hours}\][/tex]

  Now subtract the remaining hours:

  [tex]\[6 \text{ hours} - 2 \text{ hours} = 4 \text{ hours}\][/tex]

So, the corrected calculation is:

6 hr 65

4 hr 25 min -

2hr 40 min

---------------

1hr 45 minutes

Answer:

y + 1 = 3(x - 5)   Answer

Step-by-step explanation:

Find the slope of the perpendicular line.

m1 * m2 = - 1

m1 = - 1/3

m2 is the slope of the perpendicular

(-1/3) * m2 = - 1             Multiply both sides by -3

-(3)(-1/3) * m2 = -1 * -3  

m2 = 3

The slope of the perpendicular line is 3

Find the equation of the line.

m = (y - y1)/(x -x1)

y - y1 = m(x - x1) is the equation of the line.

y1 =5

x1 = - 1

(y - - 1) = 3(x - 5)

y + 1 = 3(x - 5)   Answer

Answer:

9,90

Step-by-step explanation:

Since their lack is 90, we can divide 810 by 90 and get 9. So 9 is their common factor. So 9 and 90.

To find two numbers with 90 as their LCM and 810 as their product, prime factorize 810, and choose two numbers from the prime factors that satisfy the conditions.

The question asks to find two numbers that have 90 as their lowest common multiple (LCM) and 810 as their product.

To find these numbers, we need to first prime factorize 810. The prime factorization of 810 is 2 x 3 x 3 x 3 x 3 x 5.

Now, we need to choose two numbers from these prime factors such that their product is 810 and their LCM is 90. Since 90 = 2 x 3 x 3 x 5, we can choose 3 x 3 x 2 = 18 and 5 as the two numbers.

Answer:

$110

Step-by-step explanation:

A = P(1 + r/n)ⁿ⁺

A = 100(1 + .02/1)¹⁽⁵⁾

A =  100(1.10)

A = $110

Using the simple interest formula, you can calculate that after 5 years at an annual interest rate of 2%, an initial deposit of $100 in a savings account would grow to $110.

The subject of this question is simple interest, which is important in Mathematics. To calculate how much money would be in your account after 5 years with an interest rate of 2% per annum, you would utilize the simple interest formula:

Interest = Principal x Rate x Time (I = PRT)

The principal (P) is the initial amount of money, which is $100. The rate (R) is the interest rate per period. The time (T) represents the number of periods.

In our case: The principal is $100, the rate is 2% (or 0.02 in decimal form), and the time is 5 years. Substituting these values into the formula gives. Interest = $100 x 0.02 x 5 = $10. After 5 years, you are entitled to $10 interest. This means the total amount in your account will be your initial principal plus the earned interest: $100 + $10 = $110.

Answer:

Price in Japan= 17.81

Price in Switzerland = 13.58

Step-by-step explanation:

First set up system of equations

80.59 = 3j +2s

76.36 = 2j + 3s

Make it to where you can eliminate one variable

161.18 = 6j +4 s

-229.08 = -6j - 9s

Reset the problem

-67.9 = -5s

s=13.58

Re plug them in to the original equation to get j = 17.81

By solving a system of linear equations formed from the given information, we found the average cost of a movie ticket in Japan to be $24.60, and in Switzerland to be $6.79.

Let's denote J as the cost of a movie ticket in Japan and S as the cost of a movie ticket in Switzerland. From the problem, we establish two equations: 3J + 2S = $80.59 and 2J + 3S = $76.36. This is a system of linear equations that can be solved by substitution or elimination. If you choose elimination, add these two equations together, which results in 5J + 5S = $156.95, or J + S = $31.39. Now, substitute (J + S) in first equation, we get 3J + 2(31.39 - J) = 80.59. Solving this equation we find J = $24.60. Thus, the price of a movie ticket in Switzerland is S = $31.39 - $24.60 = $6.79. Therefore, a movie ticket in Japan costs $24.60 on average, and in Switzerland, it costs $6.79.

Hope this helped!

Answer:

5 gallons

Step-by-step explanation:

Number of x's on  1/4 = 3

So, amount of sap trees produce that day = 3/4

Number of x's on 3/8 = 2

So, amount of sap trees produce that day = 2 × 3/8 = 3/4

Number of x's on 5/8 = 4

So, amount of sap trees produce that day = 4 ×5/8 = 5/2

Number of x's on 1 = 1

So, amount of sap trees produce that day = 1 × 1 =1

Therefore,

total amount of sap the trees produce =  amount of sap trees produce based on number of x's on 1/4 +  amount of sap trees produce based on number of x's on 3/8 +  amount of sap trees based on number of x's on 5/8 + amount of sap trees based on number of x's on 1 = [tex]\frac{5}{2}+\frac{3}{4}+\frac{3}{4}+1=\frac{10+3+3+4}{4}=\frac{20}{4}=5\,\,gallons[/tex]

Answer:

The account after 20 years is $73798.8.

Step-by-step explanation:

Given : James and Terry open a savings account that has a 2.75% annual interest rate, compounded monthly. They despoit $400. Into the account each month.

To find : How much will be in the account after 20 years ?

Solution :

Using monthly payment formula,

[tex]M=\frac{\text{Amount}}{\text{Discount factor}}[/tex]

Discount factor is [tex]D=\frac{1-(1+i)^{-n}}{i}[/tex]

Substitute in the formula,

[tex]\text{Amount}=M\times \frac{1-(1+i)^{-n}}{i}[/tex]

Where, M=$400 amount deposited monthly

r= 2.75%=0.0275 is the interest rate

[tex]i=\frac{0.0275}{12} =0.00229[/tex]

t=20 years is the time

[tex]n=12\times 20=240[/tex]

Substitute the value,

[tex]\text{Amount}=400\times \frac{1-(1+0.00229)^{-240}}{0.00229}[/tex]

[tex]\text{Amount}=400\times \frac{1-0.5775}{0.00229}[/tex]

[tex]\text{Amount}=400\times 184.497[/tex]

[tex]\text{Amount}=73798.8[/tex]

Therefore, the account after 20 years is $73798.8.

Answer:

The null and alternative hypotheses are:

[tex]H_{0}: p=0.67[/tex]

[tex]H_{a} : p <0.67[/tex]

Under the null hypothesis, the test statistic is:

[tex]z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]

Where:

[tex]\hat{p}= \frac{23}{42} = 0.5476[/tex]

[tex]\therefore z = \frac{ 0.5476 -0.67}{\sqrt{\frac{0.67(1-0.67)}{42} }}[/tex]

         [tex]=\frac{-0.1224}{0.072555398}[/tex]

         [tex]=-1.69[/tex]

Now, we have to find the left tailed z critical value at 0.01 significance level using the standard normal table. The z critical value at 0.01 significance level is:

[tex]z_{critical} = -2.33[/tex]

Conclusion: Since the test statistic does not fall in the critical region, therefore, we fail to reject the null hypothesis, and conclude that there is not sufficient evidence to say that the population proportion of women athletes who graduate from the university is now less than 67%.

Answer: No

By considering the given information , the null and the alternative hypotheses will be :-

[tex]H_0: p=0.67\\\\H_a: p<0.67[/tex]

Since the alternative hypotheses is left-tailed , so the test applied here is left-tailed.

Sample size : n= 42

The sample proportion of graduated : [tex]\hat{p}=\dfrac{23}{42}\approx0.55[/tex]

The test statistic for population proportion :-

[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}[/tex]

i.e. [tex]z=\dfrac{0.55-0.67}{\sqrt{\dfrac{0.67(1-0.67)}{42}}}\approx-1.65[/tex]

The p-value : [tex]P(z<-1.645)=0.0494715[/tex]

Since the p-value is greater than the significance level, then we do not reject the null hypothesis.

Hence, it does not give enough evidence to indicate that the population proportion of women athletes who graduate from the university is now less than 67%.

Step-by-step explanation:

b + 2c + 3jb + 2c + 3j =

88 + 2(33) + 3(44)(88) + 2(33) + 3(44) =

88 + 66 + 396 + 66 + 132 = 748 trees

After Ben spends 88 hours chopping, Cam spends 33 hours chopping, and Justin spends 44 hours chopping, they chop down a total of 286 trees.

To find the total number of trees chopped down, we'll use the given formula: ( b + 2c + 3j ), where ( b ) is the number of hours Ben spends chopping, ( c ) is the number of hours Cam spends chopping, and ( j ) is the number of hours Justin spends chopping.

Given that Ben spends 88 hours chopping ( b = 88 ), Cam spends 33 hours chopping ( c = 33 ), and Justin spends 44 hours chopping ( j = 44), we can substitute these values into the formula.

Plugging in the values:

[tex]\[ \text{Total trees} = 88 + 2(33) + 3(44) \][/tex]

Now, we calculate each term:

[tex]\[ 2(33) = 66 \][/tex]

[tex]\[ 3(44) = 132 \][/tex]

Then, we add up all the terms:

[tex]\[ \text{Total trees} = 88 + 66 + 132 \][/tex]

[tex]\[ \text{Total trees} = 286 \][/tex]

So, after Ben spends 88 hours chopping, Cam spends 33 hours chopping, and Justin spends 44 hours chopping, they chop down a total of 286 trees.

Step

Answer: 7 hours 12 minutes

Step-by-step explanation:

Let he needs x hours to make 1 kg of meat.

Therefore, time taken in making 5 kg of meat = 5 × x = 5x hours.

But, According to the question,

He needs 12 hour to cook 5 kg of meat.

Thus, 5 x = 12

⇒ [tex]x = \frac{12}{5}[/tex] ( By dividing both sides by 5 )

⇒ He needs [tex] \frac{12}{5}[/tex] hours to make 1 kg of meat.

⇒ The time taken to cook 3 kg of meat = [tex]3\times \frac{12}{5}=\frac{36}{5} [/tex]

= [tex]7\frac{1}{5}[/tex]  hours ⇒ 7 hours 12 minutes

Hence, He needs 7 hours 12 minutes time to cook 3 kg of meat.

After calculating, we determined that Myron needs 54 minutes to cook 3 kilograms of meat.

This problem can be solved by setting up a proportion since it involves a direct ratio between the weight of meat and the cooking time.

The given ratio is 1 1⁄2 hours for 5 kilograms of meat (1:5 ratio). To find the time needed for 3 kilograms of meat, use the proportion:

    5 kg      :-      1 1⁄2 hours
    3 kg      :-       x hours

Solving for x yields the following:

    5 kg  /  3 kg  =  1 1⁄2 hours  /  x hours
             x  =  (1 1⁄2 hours × 3 kg)  /  5 kg

Converting 1 1⁄2 hours to minutes (90 minutes) and then performing the multiplication and division:

             x  =  (90 minutes × 3)  /  5
             x  =  270 minutes  /  5
             x  =  54 minutes

Thus, Myron needs to cook 3 kilograms of meat for 54 minutes.

Answer:

52.4%

Step-by-step explanation:

Simply multiply the value with 100 to find the percentage

thus 0.524× 100 = 52.4%

To convert the decimal 0.524 to a percentage, you multiply it by 100, which results in 52.4%.

To convert 0.524 to a percentage, you multiply the number by 100. This is because when converting a decimal to a percentage, you are essentially calculating how many parts out of 100 it represents. Thus, converting the decimal 0.524 to a percentage involves the calculation:

0.524 × 100 = 52.4%.

So, the decimal 0.524 is equal to 52.4% when expressed as a percentage. This concept is useful in various contexts such as interpreting statistics, understanding the rise in cost of living, or when calculating a rate of growth or decline in a given scenario.

Answer:

(p-2l)/2 = w

Step-by-step explanation:

p=2l+2w

We want to solve for w.

The first step is to subtract 2l from each side

p-2l=2l-2l+2w

p-2l=2w

Then we will divide each side by 2 to isolate w

(p-2l)/2 = 2w/2

(p-2l)/2 = w
