PLZ ANSWER WILL GIVE BRAINLIEST!!!

Answer:

y = -27 when x = 9 and z = -3

Step-by-step explanation:

y = kxz is the joint variation where k is a constant

Substitute the knowns in to find k

-50 = k( -10)(5)

-50 = -50k

k = 1

y = xz

Now find y

y = 9*-3

y = -27 when x = 9 and z = -3

Answer:

8 in

Step-by-step explanation:

Area = (diagonal 1 x diagonal 2)/2

60 = (diagonal 1 x 15)/2

60 x 2 = diagonal 1 x 15

120 = diagonal 1 x 15

diaognal 1 = 120/15 = 8

Answer:

80.56

Step-by-step explanation:

To find the rectangle area you just multiply its length by its width:

17 * 4 = 68

You have to sum two semicircles on top of that. Since it is 2 semicircles you can just calculate one circle. Using the circle area formula:  [tex]\pi*r^2[/tex]

Since the radius (r) is 2 and [tex]\pi[/tex] is 3.14, you have the following equation:

A = 3.14 * 2² ==>      A = 3.14 * 4   ==>   A = 12.56     (A is Area)

Sum the rectangle's area with the circle's area:

12.56 + 68 = 80.56

And vuoila! there's your answer.

Answer:

871 and 1/2 ft.  

Answer: x < 10

Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the x term which in this case is 6x by adding 5 to both sides.

That leaves you with 6x < 60 and now just divide both sides by 2 and x < 10.

Notice that because we divide both sides of the inequality

by a positive number, not a negative, we did not change the

direction of the inequality sign.

Finally, put your answer in set notation, {x: x < 10}.

Unlike an equation which normally has one solution, the answer to an inequality must be stated as a solution set because an entire set of answers will work. In this problem, it's any number less than 10.

Answer:

with times hight

Step-by-step explanation:

multiply with and hight together to get a full lay out of the prisms and if the are halves i usauly add them together to form one unite hope this help and that were on the same page

Answer:

To use a unit cube, you have to multiply the length and the width just like finding the area of a 2D shape. You will then take your "area" and multiply that by the height of the object.

Step-by-step explanation:

Example, if I have a rectangular prism that is 10 inches long, 4 inches wide, and 6 inches tall, I can multiply 10 and 4 to get 40. I will then take the 6 inches, and multiply it to 40. 40x6=240. The volume of my prism is 240.

I would also like to point out that you can multiply the factors in any order because of the commutative property

i am estimating x = 6 2/3

since 5+4 = 9

9-3 = 6

so about 6 2/3?

i think

Answer:

x = 6 2/3

Step-by-step explanation:

The product of the segments are equal

x * 3 = 5 * 4

x * 3 = 20

divide both sides by 3

x = 20/3

x = 6 2/3

The domain and range of function Y = sin X will be all the real numbers and  [tex]-1\leq y\leq 1[/tex].

The domain is the set of values for which the given function is defined.

The range is the set of all values which the given function can output.

We have been given a function Y = sin X.

We need to find the domain and range of function .

Here we can see that the given function is a sine function.

So, the domain of the function would be all the real numbers.

also, The range will be [tex]-1\leq y\leq 1[/tex].

Answer: 6.25 yards

Step-by-step explanation:

75 inches = 4 bows

To get 12, you have to multiply 4 by 3. Therefore, you also have to multiply 75 by 3.

75*3 is 225.

225 inches = 12 bows

225 inches is 6.25 yards. Hope this helps :)

The value of an exterior angle is equal to the sum of values of two opposite interior angles.

That is :

Therefore, value of x is 20°

And the measure of missing angle is :

The Value of an Exterior angle is equal to the sum of values of two opposite interior angles .

Hence,

And therefore measure of missing angle is 36°, since v was the missing angle here.

Answer: The coefficient of determination = 0.6291

Step-by-step explanation:

Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.

The coefficient of determination is computed as:

[tex]\text{ coefficient of determination} =\frac{\text{explained variation }}{\text{total variation}}[/tex]

Substituting given values, we get

[tex]\text{coefficient of determination} =\frac{15.405}{24.488}[/tex]

[tex]=0.6291[/tex]

Therefore, the coefficient of determination = 0.6291

Answer:

A 11.1%

Step-by-step explanation:

The students are chosen from a sample without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question, we have that:

13 + 7 = 20 teachers, which means that N = 20.

7 history teachers means that k = 7.

Two teachers for each student, which means that n = 2.

What is the approximate probability that a random student on the trip will be assigned to a group led by two history teachers?

This is P(X = 2). So

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 2) = h(2,20,2,7) = \frac{C_{7,2}*C_{13,0}}{C_{20,0}} = 0.1105[/tex]

So close to 11.1%, and the correct answer is given by option A.

Explanation for Number 7.

The exterior angle is always equl to the sum of the two opposite interior angles.

The two opposite interior angles: 62 and (7x + 14)

The exterior angle: (15x - 4)

So you would set it up like _____ = ______ to solve for x

62 + (7x +14) = 15x - 4

62 + 7x + 14 = 15x - 4

Then move the terms

76 + 7x = 15x - 4

Collect the like terms and Calculate

7x - 15x = -4 - 76

Divide both Sides

-8x = -80

/8       /8

-x = -10

/-1    /-1

x = 10
