Answer:

$\frac{7}{10}$

Step-by-step explanation:

This is a question related to absolute value, absolute values are irrespective of sign.

$\bigg| \frac{-7}{10}\bigg| =\frac{7}{10}$

Solve for the variable r

Sonja [21]

Answer:

see explanation

Step-by-step explanation:

Given

V = πr²h ( isolate r² by dividing both sides by πh )

$\frac{V}{h\pi }$ = r² ( take the square root of both sides )

$\sqrt{\frac{V}{h\pi } }$ = r

It is to be noted that the blanks can only be filled with f(x), range, and domain.

<h3>What are the complete sentences?</h3>

The domain of a function is the set of all input values, or x-values, for which the function is defined.

The range of a function is the set of all output values, or y-values, for which the function is defined.

To write the equation y = ax + b in function notation, substitute f(x) for y.

In the figure given l || m , then find the value of X.

Aleks [24]

Answer:

Step-by-step explanation:

Line m and l are parallel so C and where that intersection is on the inside have the parallel lines, the angle there is an same side interior angle with C. Those add up to 180 degrees. So 180-82 is 98. Use vertical angle to find the angle in the triangle (not x yet; the other one). Vertical angles are congruent so that one is 98.

Now angles in a triangle add up to 180 degrees.

So we have 40+98=138.

The difference between 180 and 138 is 180-138=42 (that is x)

Answer:

The 95% confidence interval for difference between population proportion is (-0.0194, -0.0006).

Step-by-step explanation:

The confidence interval for difference in population proportion formula is,

$(\hat p_{2}-\hat p_{2})\pm z_{\alpha/2}\times \sqrt{\frac{\hat p_{1}(1-\hat p_{1})}{n_{1}}+\frac{\hat p_{2}(1-\hat p_{2})}{n_{2}}}$

The given information is:

n₁ = 11508

X₁ = 921

n₂ = 4967

X₂ = 452.

Compute the sample proportion values as follows:

$\hat p_{1}=\frac{X_{1}}{n_{1}}=\frac{921}{11508}=0.08\\\\\hat p_{2}=\frac{X_{2}}{n_{2}}=\frac{452}{4967}=0.09\\$

The critical value of z for 95% confidence interval is:

$z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96$

*Use the standard normal table.

Compute the 95% confidence interval for difference between proportions as follows:

$CI=(\hat p_{2}-\hat p_{2})\pm z_{\alpha/2}\times \sqrt{\frac{\hat p_{1}(1-\hat p_{1})}{n_{1}}+\frac{\hat p_{2}(1-\hat p_{2})}{n_{2}}}\\=(0.08-0.09)\pm1.96\times \sqrt{\frac{0.08(1-0.08)}{11508}+\frac{0.09(1-0.09)}{4967}}\\=-0.01\pm0.0094\\=(-0.0194, -0.0006)$

Thus, the 95% confidence interval for difference between population proportion is (-0.0194, -0.0006).
