Find the values of x and y

julsineya [31]

Answer:

y = 70 degrees

x = 11

Step-by-step explanation:

The side opposite x + 2 is equivalent so they will both be equal to 13.

To get the meaning of x, simply subtract 2 from 13 giving you x = 11.

Y is across from corner C, which is 70 degrees. These angles are equivalent to each other, meaning that angle y is also 70 degrees.

Hope this helps you :)

jekas [21]

Answer:

The data provide sufficient evidence that older people are more likely to be victimized.

Step-by-step explanation:

H 0 : P = 0.10

H 1 : P > 0.10 (Right tailed test)

n = 527, P = 0.1235

The test statistics

x = P - p / $\sqrt{p*(1-p) / n}$

x = 0.1235 - 0.10 / $\sqrt{0.10 * 0.90 / 527}$

x = 0.0235 / $\sqrt{0.09 / 527}$

x = 0.0235 / $\sqrt{0.00017077798}$

x = 0.0235 / 0.0130682049264618

x = 1.798257689731729

x = 1.798

P value = [1 - p(Z > 1.7980] (Right tailed test)

P value = 0.036089

The P - Value is very small, so <u>reject H0</u>

Conclusion: The data provide sufficient evidence that older people are more likely to be victimized.

Find the value of X so that the function has the given value t(x)=3x; t (x)= 24

Fed [463]

Answer:

here is your answer....

Step-by-step explanation:

lets take x as 8

t(8)=3*8

t(8)=24

Therefore:

we get t(x)=24 from equation t(x)=3x

zaharov [31]

Answer:

$\angle CFD =105^o$

Step-by-step explanation:

Given

$\angle D FE = \angle DE F = 75^o$

See attachment

Required

Determine the measure of $\angle CFD$

$\angle CFD$ and $\angle DFE$ are on a straight line.

So:

$\angle CFD + \angle DFE = 180^o$ --- angle on a straight line

Substitute known values

$\angle CFD + 75^o = 180^o$

Collect like terms

$\angle CFD =- 75^o + 180^o$

$\angle CFD =105^o$
