Answer:

m∠1 = 67.4° m∠2 = 104.5°

Step-by-step explanation:

17.3 + m∠2 = 121.8

m∠2 = 104.5°

m∠1 + 37.1 = m∠2 = 104.5

m∠1 = 67.4°

Answer:

Angle 1 = 102

Angle 2 = 40.9

Step-by-step explanation:

$1)\ 180 - 121.8 = 58.2$

$2)\ angle\ 2 = 58.2 - 17.3 = 40.9$

$3)\ angle\ 1 = 180 - 40.9 - 37.1 = 102$

Do all parent functions pass through (0,0)

dlinn [17]

Nope.

An example would be the graph of $y = \log x$ . The graph does not pass through (0, 0) as it is undefined.

A study done by researchers at a university concluded that 70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and 95% confidence interval for the study?

Answer:

Step-by-step explanation:

Given that:

The sample proportion $\hat p = 0.70$

The sample size n = 1800

At 95% confidence interval level:

The level of significance = 1 - 0.95 = 0.05

Critical value: $Z_{0.05/2} = Z_{0.025} = 1.96$

Thus, the Margin of Error E = $Z_{\alpha/2} \times \sqrt{\dfrac{\hat p ( 1- \hat p)}{n}}$

$= 1.96 \times \sqrt{\dfrac{ 0.70 ( 1-0.70)}{1800}}$

$= 1.96 \times \sqrt{\dfrac{ 0.70 ( 0.30)}{1800}}$

$= 1.96 \times \sqrt{\dfrac{0.21}{1800}}$

$= 1.96 \times \sqrt{1.16666667\times 10^{-4}}$

the Margin of Error E = 0.021

At 95% C.I for the population proportion will be:

$= \hat p \pm Z_{\alpha/2} \sqrt{\dfrac{\hat p(1- \hat p)}{n}}$

= 0.70 ± 0.021

= (0.70 - 0.021, 0.70 + 0.021)

= 0.679, 0.721)

What is greater 3/4 or 11/16

Musya8 [376]

11/16 = 11/16

3/4 = 12/16 because 4x4 is 16 and 3x4 is 12

3/4 is bigger.

In two or more complete sentences, explain how to use ordered pairs of points in f(x) = 3x - 5 and g(x) = x+5/3 to determine if

Ostrovityanka [42]

Answer:

for any point (x, y), that appears in one function, the point (y, x) must appear in the other function. for any point (x, y), that doesn't appear in one function, the point (y, x) must not appear in the other function.

so if you find any point that doesn't meet the above rules, you can prove that the functions are not inverses of each other.

to prove that they are inverses of each other, you need to check all points in the functions, and there is an infinity of them, so instead, you can write f(x) like this:

y = 3x - 5

solve for x:

y + 5 = 3x

x = (y + 5) / 3

swap x and y:

y = (x + 5) / 3

this is the same as g(x) which, therefore the functions are inverse of each other.
