valentinak56 [21]

Incomplete Question the complete Question with figure is below.

Answer:

Therefore the length of line Segment BC is 20.5 in.

Step-by-step explanation:

Given:

In Right Angle Triangle ABC

∠C = 90°

∠B = 35°

BC = a

AB = hypotenuse = 25

\cos 35\°=\dfrac{a}{25}

To Find:

BC = ?

Solution:

In Right Angle Triangle ABC , Using Cosine Identity we get

\cos B = \dfrac{\textrm{side adjacent to angle B}}{Hypotenuse}\\

Substituting we get

\cos 35 = \dfrac{a}{25}\\\\a=25\times 0.8191=20.47\\\\a=20.5\ in

Therefore the length of line Segment BC is 20.5 in.

Tyrell's SAT math score was in the 64th percentile. If all SAT math scores are normally distributed with a mean of 500 and a sta
jarptica [38.1K]

Answer:

P(x < 535.8) = 0.64

P_{64} = 535.8

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 500

Standard Deviation, σ = 100

We are given that the distribution of SAT score is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.64

P(X<x) = 0.64

P( X < x) = P( z < \displaystyle\frac{x - 500}{10})=0.64  

Calculation the value from standard normal z table, we have,  p(z

\displaystyle\frac{x - 500}{100} = 0.358\\x = 535.8

P(x < 535.8) = 0.64

P_{64} = 535.8
