Y = -5x + 15 2x + y = 12
Nana76 [90]

Answer:

x = 1, y = 10

Step-by-step explanation:

y = -5x + 15 --- Equation 1

2x + y = 12 --- Equation 2

Substitute y = -5x + 15 into Equation 2:

2x + y = 12

2x - 5x + 15 = 12

Evaluate like terms.

15 - 3x = 12

Isolate -3x.

-3x = 12 - 15

Evaluate like terms.

-3x = -3

Find x.

x = -3 ÷ -3

x = 1

Substitute x = 1 into Equation 2:

2x + y = 12

2(1) + y = 12

2 + y = 12

Isolate y.

y = 12 - 2

y = 10

A ball has a radius of 8 cm. What is the volume of the ball? Use 3.14 for pie Round your answer to the nearest tenth of a cubic
AveGali [126]

The volume of the ball is 33.5 cubic centimeter.

<u>Step-by-step explanation:</u>

It is given that, a ball has a radius of 8 cm.

We know that, the ball is in shape of the sphere.

The question is asked to find the volume of the ball.

To find the volume of the ball, you need to use the formula for volume of the sphere.

Volume of the sphere = (4/3)πr³

where,

  • π has the default value of 3.14
  • r is the radius of the ball.

Volume of the ball = (4/3)× 3.14× 8

⇒ 33.49

⇒ 33.5 (rounded to the nearest tenth)

⇒ 33.5 cubic centimeter.

∴ The volume of the ball is 33.5 cubic centimeter.

A private opinion poll is conducted for a politician to determine what proportion of the population favors adding more national
Ksju [112]

Answer:

n≅376

So sample size is 376.

Step-by-step explanation:

The formula we are going to use is:

n=pq(\frac{z_{\alpha/2}}{E})^{2}

where:

n is the sample size

p is the probability of favor

q is the probability of not in favor

E is the Margin of error

z is the distribution

α=1-0.98=0.02

α/2=0.01

From cumulative standard Normal Distribution

z_{\alpha/2}=2.326

p is taken 0.5 for least biased estimate, q=1-p=0.5

n=0.5*0.5(\frac{2.326}{0.06})^{2}\\n=375.71

n≅376

So sample size is 376
