Please help!!! I only have three questions left!!!

Answer:

1.  P ( tails) = 1/2

2.P (number greater than 4)   = 1/3

3.  P (2 die sum to 8) = 5/36

Step-by-step explanation:

A coin only has 2 possibilities, head or tails, and they are equally likely

So the probability of getting a tails is 1/2

P ( tails) = 1/2

A die has the numbers 1,2,3,4,5,6 .  There are 2 numbers greater than 4.  They are 5 and 6.  So there are 2 of the 6 choices that work.

P (number greater than 4)  = 2/6  = 1/3

See the dice chart

There are 36 possibilities when you roll the die.

There are 5 that sum to 8

P (2 die sum to 8) = 5/36

Answer:

Guy above is correct

Step-by-step explanation:

The x-value that makes the line through the points (x, -9) and (0, 1) have a slope of -4 is x = 5/2 or 2.5.

To find the x-value that makes the line through the points (x, -9) and (0, 1) have a slope of -4, we can use the slope formula:

slope = (change in y) / (change in x)

Given that the slope is -4 and the two points are (x, -9) and (0, 1), we can plug the values into the slope formula:

-4 = (-9 - 1) / (x - 0)

Now, simplify the equation:

-4 = -10 / x

Now, cross-multiply:

-4x = -10

Now, solve for x by dividing both sides by -4:

x = -10 / -4

x = 5/2

So, the x-value that makes the line through the points (x, -9) and (0, 1) have a slope of -4 is x = 5/2 or 2.5.

Answer:

∠6 > ∠3 is TRUE.

Step-by-step explanation:

We know that acute angle is less than 90 degree while obtuse angle is more than 90 degree. By looking at the given angles, we can easily determine which angle is obtuse or acute. then we can decide which angle is bigger to find the answer.

∠10 > ∠7

FALSE;

Because∠10 is acute while ∠7 is obtuse.

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

∠6 > ∠3

TRUE;

Because∠3 is acute while ∠6 is obtuse.

D

Step-by-step explanation:

An inequality is an expression which means more than one number is a solution. We graph the solutions on a number line to show all possible values. We graph using circles and arrows.

Step-by-step explanation:

Let S = spoon

Let K = knife

1 knife is thee times the cost of a spoon, so it would be 3S

Now you have 9S + 12K = 82.80

We can replace the K with 3S:

9S +12(3S) = 82.80

Simplify the left side:

9S + 36S = 82.80

Add:

45S = 82.80

Divide both sides by 45"

S = 82.80 / 45

S = 1.84

One spoon cost $1.84

We know one knife cost 3 times as much, so multiply the cost of a spoon by 3:

Knife = 1.84 x 3 = $5.52

Answer:

1.84 x 3 = $5.52

Answer:

Number of metric tons of corn produced by country A = 373 million MT

Number of metric tons of corn produced by country B = 234 million MT

Number of metric tons of corn produced by country C = 57 million MT

Step-by-step explanation:

From the given information we have

A+B+C = 664 ____equation(1)

A = B+C+82 ____equation(2)

B = C + 177 ____equation(3)

1) Plugging in B=C+177 into equation 2, we get

A = B+C+82

=> A = (C+177) + C +82

=> A = C+177+C+82

=> A = C +C +177+82

=> A= 2C +  259 ____let it be equation (4)

2) Plugging in A=2C+259 from equation 4 and B=C+177 from equation 3 into the equation 1, we get

A+B+C = 664

=> (2C+259)+(C+177)+C = 664

=> 2C+C+C+259+177 = 664

=> 4C + 436 = 664

3) Subtracting 436 from both the sides, we have

4C + 436 - 436 = 664 - 436

4) Cancelling out +436 and -436 from the left side, we get

4C = 228

5) Dividing both the sides by 4, we get

[tex]\frac{4C}{4} = \frac{228}{4}[/tex]

6) Cancelling out the 4's from the left, we get

C = 57

7) Plugging in C=57 into the equation 3, we get

B = C + 177

=> B = 57+177

=> B = 234

8) Plugging in B=234 and C=57 into the equation 1, we get

A+B+C = 664

=> A+234+57=664

=> A + 291= 664

9) Subtracting 291 from both the sides, we get

A + 291 - 291 = 664 - 291

10) Cancelling out +291 and -291 from the left side, we get

A = 373

So, A = 373, B= 234, C=57

Answer:

Adriano's this month earning is $1150

Step-by-step explanation:

Adriano's existing customers =200

Every customer Pays subscription fee = $5 per month

This month number of customers joined =40

And number of number of customers cancelled subscription =10

So this month addition of new customers = 40-10 =30

Therefore total numbers of subscribers =200+30 =230

And money earned this month = 230× $5

                                                   = $1150

Answer:

-15 is how many tests per hour i think, and 78 is how many tests total

Step-by-step explanation:

= 78 − 15ℎ

1 hour would be

78-(15x1)=63

2 hours would be

78-(15x2)=48

and so on.

Final answer:

The value 78 represents the initial number of tests Mrs. Hool has, while -15 represents the rate at which she grades tests per hour.

Explanation:

The values 78 and -15 in the equation represent the initial number of tests that Mrs. Hool has and the rate at which she grades the tests per hour, respectively.

The value 78 is the initial number of tests that Mrs. Hool has left to grade. This means that when she starts grading, she has 78 tests remaining.

The value -15 represents the rate at which Mrs. Hool grades the tests per hour. It indicates that for every hour she works on grading, she is able to complete 15 fewer tests than what she started with. In other words, the number of tests she has left decreases by 15 for every hour she works.

Answer:

Total = 686000 meters for 10 weeks 7 days a week.

Step-by-step explanation:

Let's solve this by doing the increase on just 1 training day per week. Then we can find the grand total for 7 days a week by multiplying by 7

a = 8000

n = 10

d = 400

Sum = (a + L)*n/2

Sum = (8000 + 11600)*10/2

Sum = 19600 * 10/2

Sum = 98000 meters.

This total represents 1 training day a week.

The total amount is 7 times this figure.

Total = 7 * 98000 = 686 000 meters.

Answer:

a. -2, even mult. and 1, odd mult.

b.[tex](x+2)^2(x-1)[/tex]

c. Odd degree of 3 or higher, likely higher due to the turns in the graph.

Step-by-step explanation:

A polynomial graph has several features we look for to determine the equations.

In this graph, there are two real zeros: -2,1

We can write them in intercept or factored form as (x-1) and (x+2).  

Because the graph never crosses the x-axis at x=-2 the zero has an even multiplicity of at least 2.  The opposite is true for x=1 because it crosses. Therefore it has an odd multiplicity of at least 1.

The graph is a sideways s shape and ends up so is positive.  

This means the function has a degree of 3 or higher with the degree being odd.

Answer:

150 feet

Step-by-step explanation:

in order to find the solution we have to take the L.C.M of 25 and 30

L.C.M of 25 and 30 is 150

so after 150 feet , they will both fall down

Answer: They will both fall down after 150 feet.

Step-by-step explanation:

Hi, to answer this question we have to find the least common multiple (LCM)

of 30 and 25:

To obtain the multiple of a number we have to multiply that number by another number (not zero) in the multiplication table order (by 1,by 2,by 3,etc)

30,60,90,120,150

25,50,75,100,125,150

The LCM is a number that appears on both lists, and is the smallest.

They will both fall down after 150 feet.

64.5A

Step-by-step explanation:

[tex]f(x)=x^3+3x^2-10x-24\\\\y-intercept\ for\ x=0:\\\\f(0)=0^3+3(0)^2-10(0)-24=-24[/tex]

Answer:

The attached image shows he graph for given function.

Step-by-step explanation:

We are given the following expression in the question:

[tex]f(x) = x^3 + 3x^2-10x-24[/tex]

The zeroes of the given function can be calculated as:

[tex]x^3 + 3x^2-10x-24 = 0\\x = -4, x = -2, x=3[/tex]

Thus,the graph for the given function passes through the x-axis on the points (-4,0), (-2,0) and (3,0).

The function crosses the y-axis at the point (0,24)

The attached image shows the graph for given function.

Thus, the second option is the correct graph for given function.
