Answer:

Jane had 20 stamps in the beginning

Step-by-step explanation:

* Lets study the information in the problem

- Jane has unknown numbers of stamps

- She gave 10 of them to her friend

- Her mom give her twice as many stamps as she had in the beginning

* To solve the problem let the unknown numbers of stamps = x

∵ Jane had at the beginning x stamps

- She gave her friend 10 of them

∴ The rest with her = x - 10 stamps

- Her mom gave her twice as many stamps as she had in the beginning

∵ She had at the beginning x stamps

∴ Her mom gave her 2 × x = 2x

∴ The number of stamps with her now = x - 10 + 2x stamps

- She has now 50 stamps

∴ x - 10 + 2x = 50 ⇒ add the like term

∴ 3x - 10 = 50 ⇒ add 10 to both sides

∴ 3x = 60 ⇒ divide both sides by 3

∴ x = 20

∴ Jane had 20 stamps in the beginning

alice recycled 21 bottles

Answer:

21

Step-by-step explanation:

We have an equation in the first sentence we are given.  Mike and Alice together recycled 147 bottles, so in equation form that looks like this:

M + A = 147.

That alone doesn't do us much good because we have 2 unknowns.  The next sentence gives us Mike's number of bottles based on Alice's.  If the number Mike recycles is 6 times as many as Alice, replace the word "is" with an "=" and "6 times as many as Alice" with 6A to get:

M = 6A

Now we can go back to the first equation and replace M with 6A:

6A + A = 147

Now we only have A's.  That's a good thing.  Solve for A:

7A = 147

A = 21

Step-by-step explanation:

Answer: the difference in yearly median income for a female vs male at a masters degree level is

$15,642.90/year

Step-by-step explanation:

there are roughly 52.143 week in a year.

the median weekly income for a female with a masters degree is : $901.00

the median weekly income for a male with a masters degree is :

$1,201

so if you multiply $901 x 52.143 you get :

$46,980.84, which is what a female makes in a year with a md

and if you multiply $1,201 x 52.143 you get :

$62,623.74, which is what a male makes in a year with a md

subtract $62,623.74 - $46,980.84 you get :

$15,642.90 / year

Final answer:

The difference in yearly median income for a female versus male at a master's degree level is $89,804.

Explanation:

The difference in yearly median income for a female versus male at a master's degree level is $2,951 per week. To find the yearly difference, we can multiply this average by 52 weeks, which equals $153,452 per year.

Comparing this to the median yearly earnings for a full-time worker over 25 with no higher than a bachelor's degree, which is $63,648, we can see that having a master's degree more than doubles the earning potential.

Therefore, the difference in yearly median income for a female versus male at a master's degree level is approximately $89,804.

Answer:

the monthly payment is $303.69

Step-by-step explanation:

this is how i got it:

9,550 divided by 100= 95.5

95.5 x 3.18= 303.69

so the monthly payment it $303.69

Final answer:

To find Chico's monthly car payment, divide the total loan amount by $100 to determine the number of units and multiply by the monthly payment per unit, resulting in a monthly payment of $303.69.

Explanation:

The student's question relates to calculating the monthly payment of a car financing plan. To determine Chico's monthly payment for his car loan, we can use the provided information that each $100 of the loan requires a $3.18 monthly payment at an APR of 8.9%. Since Chico is financing $9,550, we first divide this amount by $100 to find the number of 'units' of $100 in the total loan amount. We then multiply that number by the monthly payment per $100 to find the total monthly payment.

Calculate the number of $100 units in the total loan amount: $9,550 / $100 = 95.5 units.

Multiply the number of units by the monthly payment per unit: 95.5 units * $3.18/unit = $303.69.

Therefore, Chico's monthly payment for the car would be $303.69.

Answer:it is false

Step-by-step explanation:

Since we are talking about inverse of a function. we would be dealing with reversal. An inverse function is function that reverses another function. Getting the inverse will require reversing the numerator and denominator. This means that the numerator becomes the denominator and the denominator becomes the numerator.

The function given is

y = 7x + 5

Let us solve to see whether the inverse is is y = x+5/7 is true or false

The numerator is 7x + 5 and the denominator is 1

The inverse becomes 1 / (7x + 5 )

So it is false

Answer:

Step-by-step explanation:

To start with a = 12 (given)

Tan(50) = b / 12

Tan(50) = 1.192

1.192 = b / 12             Multiply both sides by 12

1.192 * 12 = b

b = 14.301

=================

Cos(50) = 12/c

Cos(50) = 0.4628

0.4628 = 12 / c                 Multiply both sides by c

0.4628 * c = 12                 Divide by 0.4628

c = 12/ 0.4628

c = 18.67

Answer:

The right answer for the question that is being asked and shown above is that: "f(x), because an increasing exponential function will always exceeds an increasing quadratic function until their graphs intersect."  The points of f(x) compared to g(x) is more increasing.

hope this help

The graph which most likely represents the quadratic function is f(x), because an increasing exponential function will eventually exceed an increasing quadratic function.

A quadratic function is the function in which the unknown variable is one and the highest power of the unknown variable is two.

The standard form of the quadratic function is,

f(x)=ax²+bx+c

Here,(a,b, c) is the real numbers and (x) is the variable.

Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.

An increasing exponential function is eventually exceed an increasing quadratic function.

Thus, the graph which most likely represents the quadratic function is f(x), because an increasing exponential function will eventually exceed an increasing quadratic function.

The answer is 13- cedric Rhen

Step-by-step explanation:

The range for the number of cars sold at the dealership is 13 cars, calculated by subtracting the lowest sales number (4) from the highest (17).

The range for the number of cars sold by the salespeople at the dealership can be calculated by finding the difference between the maximum and minimum sales numbers. First, we identify the highest and lowest sales figures from the list provided. The highest number of sales is 17 (by Mark) and the lowest is 4 (by Manuel).

Now, subtract the minimum from the maximum to get the range: 17 (max) - 4 (min) = 13.

Therefore, the range for the number of cars sold is 13 cars.

Answer:

D. 68%

Step-by-step explanation:

The following statistics are given;

sample mean = 47%

s = 5% ; the sample standard deviation

n = 625 ; the sample size

The confidence interval for a population mean is given as;

sample mean ± z-score*[tex]\frac{s}{\sqrt{n} }[/tex]

Substituting the above values we have;

47 ± z-score*[tex]\frac{5}{\sqrt{625} }[/tex]

47 ± z-score*0.2

The confidence interval has been given as;

lower limit = 46.8%

upper limit = 47.2%

We can use any of these two values with the above expression to solve for the z-score. Using the lower limit we have the following equation;

47 - z-score*0.2 = 46.8

-z-score*0.2 = 46.8 - 47

-z-score*0.2 = -0.2

z-score = 1

The area of the standard normal curve between -1 and +1 will be the confidence level for the given confidence interval.

Pr( -1<Z<1 ) = 0.68 = 68%
