Supplementary angles are angles that together, for an angle of 180°. Straight lines are also 180°, so what you need to look for in this exercise are angles, next to eachother, on the same straight line.

those are:

1,2

1,4

2,3

5,6

5,8

6,7

7,8

3,4

so the right answers are option 1 and 2

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, $p(z$

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

$P(x < 535.8) = 0.64$

$P_{64} = 535.8$

Answer:

Step-by-step explanation:

▪Picture 1. x = 28

$\frac{x}{42} = \frac{10 + x}{57} \\ 42(10 + x) = 57x \\ 420 + 42x = 57x \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: - 42x = - 42x}{ \frac{420}{15} = \frac{15x}{15} } \\ \\ 28 = x$

▪Picture 2. I don't know what in trying to solve.

▪Picture 3.

•ABC = 50

•DEF = 95

•GHI = 65

•JKL = 55

▪Picture 4. I dont know how to do that
