If an eagle has 3 chicks per year and we need to find how much in 8 years we simply multiply the two numbers.

So,

3 x 8 = 24

Therefore, an eagle will have 24 chicks in 8 years.

Answer:

1st one 6.4

Step-by-step explanation:

C^2= a^2 +b^2

C^2 = 5^2 + 4^2

C^2 = 25 + 16

C^2= 41

Root of 41 is 6.4

Answer:

132%

Step-by-step explanation:

The population of Peru = 10904

The population of Franklin = 25248.

Difference = 25248-10904=14,344

Expressing as a percentage of the population of Peru

$\dfrac{14344}{10904} X 100$

=132%

Therefore, the population of Franklin is 132% more than the population of Peru.

A political candidate has asked you to conduct a poll to determine what percentage of people support him. If the candidate only

Nadusha1986 [10]

Answer:

The sample size required is, n = 502.

Step-by-step explanation:

The (1 - α)% confidence interval for population proportion is:

$CI=\hat p\pm z_{\alpha/2}\sqrt{\frac{\hat p\cdot (1-\hat p)}{n}}$

The margin of error is:

$MOE=z_{\alpha/2}\sqrt{\frac{\hat p\ \cdot (1-\hat p)}{n}}$

Assume that 50% of the people would support this political candidate.

The margin of error is, MOE = 0.05.

The critical value of z for 97.5% confidence level is:

z = 2.24

Compute the sample size as follows:

$MOE=z_{\alpha/2}\sqrt{\frac{\hat p\ \cdot (1-\hat p)}{n}}$

$n=[\frac{z_{\alpha/2}\times \sqrt{\hat p(1-\hat p)}}{MOE}]^{2}$

$=[\frac{2.24\times \sqrt{0.50(1-0.50)}}{0.05}]^{2}\\\\=501.76\\\\\approx 502$

Thus, the sample size required is, n = 502.

What is -6x+4=-50 and 5x+6=-44 also -3(7+6x)=-201 please solve these equations and show work

grandymaker [24]

Remember you can do anyting to an equation as long as ou do it to both sides

-6x+4=-50
minus 4 both sides
-6x=-54
divide both sides by -6
x=9

5x+6=-44
minus 6 both sides
5x=-50
divide both sides by 5
x=-10

-3(7+6x)=-201
normally you would distribute (that works) but it's easier to divide both sides by -3
7+6x=67
minus 7 both sides
6x=60
divide by 6 both sides
x=10
