Please hellp find x y and z

melomori [17]

Answer:

angle x = 98

angle y = 82

angle z = 82

Step-by-step explanation:

angle y + 98 = 180; therefore, angle y = 82 degrees

angles z and y are alternate interior angles and are congruent (equal)

angle x is 98 degrees because angles x and y are same-side interior and their angles are supplementary (add up to 180 degrees)

Married at 25. A study suggests that the 25% of 25 year olds have gotten married. You believe that this is incorrect and decide

seraphim [82]

Answer:

Given hypothesis are

H0: A = 0.24

H1: Â ≠ 0.24

Here sample proportion Â is used to express hypothesis instead of population proportion p.

The error is sample parameter Â used in hypothesis [ It should be population parameter p or π )

Find the tangent line equation of the curve at the given point. Y=arcsin(7x) at the point where x=sqrt2/14

Mumz [18]

Answer:

$Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})$

Step-by-step explanation:

The equation of the curve is

$Y = sin^{-1}(7x)$

To find the equation of tangent we need to differentiate this equation w.r.t x

So, differentiating we get

$Y'=\frac{7}{\sqrt{1-49x^2} }$

This would give the slope of the tangent line at any given point of which x coordinate is known. In the present case it is $x = \sqrt{\frac{1}{7} }$

Then slope would accordingly be

$Y'=\frac{7}{\sqrt{1-49/49} }$

= ∞

For, $x = \sqrt{\frac{1}{7} }$ , $Y = sin^{-1}(7/7)= \pi/2$

Equation of tangent line, in the point slope form, would be $Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})$

George is twice the age of Mike minus 5. The sum of George and Mike's ages is 31. How old is George and write an equation to rep

Temka [501]

Answer:

George is 19

Step-by-step explanation:

George is g and Mike is m

g = 2m - 5
g + m = 31

Substitute g in the second equation

2m - 5 + m = 31
3m - 5 = 31
3m = 36
m = 12

Finding g

g = 2*12 - 5 = 24 - 5 = 19

What is the position of F on the number line below? write your answer as a fraction or mixed number

nadya68 [22]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

There are 4 steps to complete to go from 0 to 1. Hence each step is:

1 out of 4, or simply $\frac{1}{4}$

F is located at the 3rd mark, which will be $\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{3}{4}$

Hence, F is located at $\frac{3}{4}$
