Need the answer on this

None of the answers are correct because it’s definitely not “Given” because x=20 is like an answer. It’s also not “Distributive Property”, “subtraction Property”, and or “Additional Property” b/c there’s nothing that can be distributed, subtract or add. It’s just an answer.

The mayor of a town has proposed a plan for the construction of an adjoining community. A political study took a sample of 900 v

Aleks04 [339]

Answer:

P-value = 0.0367

Step-by-step explanation:

This is a hypothesis test for a proportion.

The claim is that the percentage of residents who favor construction is significantly over 42%.

Then, the null and alternative hypothesis are:

$H_0: \pi=0.42\\\\H_a:\pi>0.42$

The sample has a size n=900.

The sample proportion is p=0.45.

The standard error of the proportion is:

$\sigma_p=\sqrt{\dfrac{\pi(1-\pi)}{n}}=\sqrt{\dfrac{0.42*0.58}{900}}\\\\\\ \sigma_p=\sqrt{0.000271}=0.016$

Then, we can calculate the z-statistic as:

$z=\dfrac{p-\pi-0.5/n}{\sigma_p}=\dfrac{0.45-0.42-0.5/900}{0.016}=\dfrac{0.029}{0.016}=1.79$

This test is a right-tailed test, so the P-value for this test is calculated as:

$\text{P-value}=P(z>1.79)=0.0367$

Can someone help with this. Heads up it's ratios

ohaa [14]

Answer:

<em>The median side measures 92 yards</em>

Step-by-step explanation:

Let's call x, y, and z the measures of the sides of the triangle.

The ratios between them are:

$\displaystyle \frac{x}{y}=\frac{4}{7}$

$\displaystyle \frac{x}{z}=\frac{4}{2}=2$

The first ratio gives the relation:

$\displaystyle y=\frac{7x}{4}$

The second ratio can be solved for z:

$\displaystyle z=\frac{x}{2}$

Since the perimeter is 299 yards:

$x+y+z=299$

Substituting the above relations:

$\displaystyle x+\frac{7x}{4}+\frac{x}{2}=299$

Multiplying by 4:

$4x + 7x+2x=1196$

Joining like terms:

$13x=1196$

Dividing by 13:

$x=1196/13$

x=92

Now calculate y:

$\displaystyle y=\frac{7\cdot 92}{4}$

y = 161

$\displaystyle z=\frac{92}{2}$

z=46

The median side measures 92 yards

3x + 3 − x + (−7) > 6 what is x

WARRIOR [948]

3x+3-x+(-7)>6

combine like terms on left side
