Answer:

y = ½x

Step-by-step explanation:

Using (4,2) and (0,0)

y-intercept is 0

Slope: (2-0)/(4-0)

2/4 = 1/2

y = ½x + 0

y = ½x

Answer:

Step-by-step explanation:

Choose any point and put it into one of the choices of equations. Let's just do (4, 2):

A) y = 2x ⇒ 2 =? 2 * 4 ⇒ 2 ≠ 8 --- eliminate

B) y =1/2x ⇒ 2 =? 4 * (1/2) ⇒ 2 = 2 --- correct; keep it

C) y = 1/2 + x ⇒ 2 =? 1/2 + 4 ⇒ 2 ≠ 4.5 --- eliminate

D) y = 2 + x ⇒ 2 =? 2 + 4 ⇒ 2 ≠ 6 --- eliminate

Thus, B is the correct answer.

Hope this helps!

janie has 196 rock and country cd's that she listens to at home if there are 76 more rock cd's than country cds how many of each

marshall27 [118]

There are 60 Country CDs and 136 Rock CDs.

Rock and country CDs = 196

Country CD = x
Rock CD = x + 76

Country CD + Rock CD = 196
x + (x + 76) = 196
2x = 196 - 76
2x = 120
2x / 2 = 120 / 2
x = 60 * number of Country CD

Rock CD = x + 76 = 60 + 76 = 136

To check:
Country + Rock = 196
60 + 136 = 196
196 = 196

Solve for x. 21) 60° 8x 80°

Elden [556K]

Answer:

x = 5

Step-by-step explanation:

Sum of angles = 180, so

60 + 80 + 8x = 180

140 + 8x = 180

8x = 180 - 140 = 40

x = 40/8 = 5

Find the volume of the pyramid below. Hint: The base is a right triangle, so you will need to find

Aleks04 [339]

Given:

Given that the height of the pyramid is 12 units.

The base of the triangle is 8 units.

The height of the triangle is 6 units.

We need to determine the volume of the pyramid.

Area of the triangle:

The area of the triangle can be determined using the formula,

$A=\frac{1}{2} bh$

where b is the base of the triangle and h is the height of the triangle.

Substituting the values, we get;

$A=\frac{1}{2}(8)(6)$

$A=\frac{1}{2}(48)$

$A=24$

Thus, the area of the triangle is 24 square units.

Volume of the pyramid:

The volume of the pyramid can be determined using the formula,

$V=\frac{1}{3}AH$

where A is the area of the triangle and H is the height of the pyramid.

Substituting the values, we get;

$V=\frac{1}{3}(24)(12)$

$V=\frac{1}{3}(288)$

$V=96$

Thus, the volume of the pyramid is 96 cubic units.

<h2>Answer with explanation:</h2>

Let p be the population proportion .

Then, $p=\dfrac{5000}{20000}=0.25$

According to the given information, we have

$a)\ \text{Null hypothesis }H_0: p=0.25\\\\b)\ \text{Alternative hypothesis} H_a: p\neq0.25$ , since alternative hypothesis is two-tailed , so the hypothesis test is a two-tail test.
