Step-by-step explanation:

Intersecting secant angles theorem: The angle between two secants is half the difference of the intersected arcs.

52 = ½ (x − 38)

x = 142

Arc angles add up to 360.

360 = 80 + 38 + z + x

z = 100

Tangent-chord theorem: The angle between a tangent and a chord is half the intercepted arc angle.

y = x/2

y = 71

If you apply the changes below to the absolute value parent function, f(x) = |x|, what is the equation of the new function?Shift

Serjik [45]

Answer: C

Step-by-step explanation:

The general form of the equation is: g(x) = a|x - h| + k ;

"a" represents the vertical stretch (or shrink)
"h" represents the x-coordinate of the vertex (left and right)
"k" represents the y-coordinate of the vertex (up and down)

4 units left means h = 4

2 units up means k = 2

--> g(x) = |x - 4| + 2

Suppose that scores on a particular test are normally distributed with a mean of 110 and a standard deviation of 20. What is the

qaws [65]

Answer:

The minimum score needed to be in the top 2% of the scores on the test

is n = 10,00,000

Step-by-step explanation:

Step(i):-

Mean of the Population = 110

Standard deviation of the Population = 20

The estimated error = 2% = 0.02

Step(ii):-

The estimated error is determined by

$E = \frac{S.D}{\sqrt{n} }$

$0.02 = \frac{20}{\sqrt{n} }$

⇒ $\sqrt{n} = \frac{20}{0.02} = 1000$

Squaring on both sides, we get

n = 10,00,000

The minimum score needed to be in the top 2% of the scores on the test

is n = 10,00,000
