PLEASE HELP 35 points <br> What is the value of Y <br> What is the value of x

Svetlanka [38]

Answer:

$\sin(58°) = \frac{12}{y} \\ y = \frac{12}{ \sin(58°) } \\ y = \frac{12}{0.85} \\ \boxed{y = 14.15(approx)}$

$\tan(58°) = \frac{12}{x} \\ x = \frac{12}{ \tan(58°) } \\ x = \frac{12}{1.6} \\ \boxed{x = 7.5(approx)}$

What is the value of x in the isosceles trapezoid below

Nookie1986 [14]

Answer:

D. 13

Step-by-step explanation:

From the diagram, $\angle BAD=2x\degree$ and $\angle BCD=(10x+24)\degree$

In an isosceles trapezium, the base angles are equal.

This implies that $\angle ABC=\angle BAD$ $\implies \angle ABC=2x\degree$

The side length CB of the trapezoid is a transversal line because <em>CD is parallel to AB</em>.

This means that $\angle ABC=2x\degree$ and $\angle BCD=(10x+24)\degree$ are co-interior angles.

Since co-interior angles are supplementary, we write and solve the following equation for $x$ .

$2x\degree+(10x+24)\degree=180\degree$

Group similar terms

$2x+10x=180-24$

Simplify both sides of the equation.

$12x=156$

Divide both sides by 12

$\frac{12x}{12}=\frac{156}{12}$

$\therefore x=13$

The correct answer is D.

Eighty percent of the students graduating from high school in a small Iowa farm town attend college. The town's chamber of comme

Answer: 0.6368

Step-by-step explanation:

Given : The proportion of z-test for population mean : $\hat{p}= 0.80$

Sample size : $n=45$

We assume that this is normally distributed.

The test statistic for population proportion :-

$z=\dfrac{\hat{p}-p_0}{\sqrt{\dfrac{p_0(1-p_0)}{n}}}$

Now, for $p_0=0.82$ , we have

$z=\dfrac{0.80-0.82}{\sqrt{\dfrac{0.82(1-0.82)}{45}}}\\\\\approx-0.35$

By using the standard normal distribution table , the probability that at least 82% of the surveyed students will be attending college will be :-

$P(p\geq0.82)=P(z\geq-0.35)\\\\=1-P(z$

Hence, the probability that at least 82% of the surveyed students will be attending college = 0.6368
