The measure of the other acute angle in the right triangle is 90 - 2y

<h3>How to determine the other acute angle?</h3>

The given parameters in the question are:

Shape = right triangle

Acute angle = 2y

The measures of acute angles in a right triangle add up to 90

This can be represented mathematically as

Acute angle + Other angle = 90

Substitute the known values in the above equation, so, we have the following representation

2y + Other angle = 90

This gives

Other angle = 90 - 2y

Hence, the other angle is 90 - 2y

Answer:

B. ZJ = 85

C. KH = 68

Step-by-step explanation:

Given that ZK, ZL, ZM are perpendicular bisectors of ∆GHJ, they form a circumcenter which is equidistant from the vertices of ∆GHJ. According to the circumcenter theorem, ZH = ZG = ZJ = 85.

Also each median formed is equal. This means: KH = GH, LH = LJ, MG = MJ

Since HG = 136, KH = ½ of 136 = 68.

The two options that are true are:

B. ZJ = 85

C. KH = 68

Answer:

5) ∅ =3.94°

6) ∅ = 22.19°

Step-by-step explanation:

5) tan ∅ = 3.9/56.67

tan ∅ = 0.0688

∅ =3.94°

6) cos ∅ = 250/270 (500/2 = 250)

cos ∅ = 0.9259

∅ = 22.19°

Evaluate the following expression 5(1 3)-3(2 -1)

BARSIC [14]

Answer:

Step-by-step explanation:

This problem tests your understanding of order of operations rules.

Here you must do any work inside parentheses first, followed by multiplication, followed by subtraction:

5(13) - 3(2 -1) would be 65 -3(1), or 62.

If you actually meant 5(1 - 3) - 3(2 - 1), then you'd have

5(-2) - 3(1) = -10 - 3 = -13

Please compare the problem you've shared with the original problem, to ensure that these match.

A study found that, in 2005, 12.5% of U.S. workers belonged to unions (The Wall Street Journal, January 21, 2006). Suppose a sam

Julli [10]

Answer:

There is not enough evidence to support the claim that union membership increased.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 400

p = 12.5% = 0.125

Alpha, α = 0.05

Number of women belonging to union , x = 52

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.125\\H_A: p > 0.125$

The null hypothesis sates that 12.5% of U.S. workers belong to union and the alternate hypothesis states that there is a increase in union membership.

This is a one-tailed(right) test.

Formula:

$\hat{p} = \dfrac{x}{n} = \dfrac{52}{400} = 0.13$

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

Putting the values, we get,

$z = \displaystyle\frac{0.13-0.125}{\sqrt{\frac{0.125(1-0.125)}{400}}} = 0.3023$

Now, we calculate the p-value from the table.

P-value = 0.3812

Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.

Conclusion:

Thus, there is not enough evidence to support the claim that union membership increased.
