The correct answer is D.

Simplify the radical by breaking the radicand up into a product of known factors, assuming the real numbers. This is very hard to explain on a keyboard because there is no square root symbols lol

Assume that you plan to use a significance level of α = 0.05 to test the claim that p1 = p2. Use the given sample sizes and numb

dezoksy [38]

Answer:

The calculated value Z = 3.775 > 1.96 at 0.05 level of significance

Null hypothesis is rejected

The Two Population proportion are not equal

Step-by-step explanation:

Given first sample size n₁ = 677

First sample proportion

$p^{-} _{1} = \frac{x_{1} }{n_{1} } = \frac{172}{677} = 0.254$

Given second sample size n₂ = 3377

second sample proportion

$p^{-} _{2} = \frac{x_{2} }{n_{2} } = \frac{654}{3377} = 0.1936$

Null Hypothesis : H₀ : p₁ = p₂.

Alternative Hypothesis : H₁ : p₁ ≠ p₂.

Test statistic

$Z = \frac{p_{1} ^{-}-p^{-} _{2} }{\sqrt{P Q(\frac{1}{n_{1} } +\frac{1}{n_{2} }) } }$

where

$P = \frac{n_{1} p_{1} + n_{2} p_{2} }{n_{1}+n_{2} } = \frac{677 X 0.254+3377 X 0.1936}{677+3377}$

P = 0.2036

Q = 1 - P = 1 - 0.2036 = 0.7964

$Z = \frac{0.254- 0.1936 }{\sqrt{0.2036 X 0.7964(\frac{1}{677 } +\frac{1}{3377 }) } }$

Z = 3.775

Critical value ∝=0.05

Z- value = 1.96

The calculated value Z = 3.775 > 1.96 at 0.05 level of significance

Null hypothesis is rejected

The Two Population proportion are not equal

Use the graph of the polynomial function to find the factored form of the related polynomial. Assume it has no constant factor.

Tpy6a [65]

Answer: C

Step-by-step explanation: If you turn all of them into a x^2 equation yk. A and D would be on the left. While B and C on the right, but B is exactly touching the y-axis when placed on the graph. And C isn’t... It matches perfectly as the one shown on the graph shown.

You need 2 eggs for a muffin recipe that makes 12 muffins. If you want to make 36 muffins, what should you do?

mixas84 [53]

Solve:-

36 ÷ 12 = 3
3 batches of 12 muffins each.

2 × 3 = 6
You will need 6 eggs to make 36 muffins, when using 2 eggs per 12 muffins.

CHECK OUR WORK:-

6 / 2 = 3
We were RIGHT!!!!

So, to make 36 muffins you need 6 eggs.
