7x - 7 = 3x + 45
4x = 52
x = 13

7x - 7 = 7(13) - 7 = 84

y - 6 = 180 - (84 + 63)
y - 6 = 180 - 147
y - 6 = 33
y = 39

What is the Greatest Common Factor of x^4 and x^3?
hammer [34]
Judging by the question I noticed that the two both share x^3 in common. You can divide x^4 by x^3 and get x as a result, and x^3 can still divide into itself.

Thus your answer should be C, x^3

nexus9112 [7]

Answer:

6

Step-by-step explanation:

Area = 1/2( base times height)

since the height is perpendicular to the base

therefore

6 = 1/2(3) h

Assume that IQ scores are normally distributed with a mean of 100 and a standard deviation of 16. If 100 people are randomly sel
laiz [17]

Answer:

0.03 is  the probability that for the sample mean IQ score is greater than 103.      

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 100

Standard Deviation, σ = 16

Sample size, n = 100

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

Formula:

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

Standard error due to sampling =

\dfrac{\sigma}{\sqrt{n}} = \dfrac{16}{\sqrt{100}} = 1.6

P( mean IQ score is greater than 103)

P(x > 103)

P( x > 103) = P( z > \displaystyle\frac{103 - 100}{1.6}) = P(z > 1.875)

= 1 - P(z \leq 1.875)

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

P(x > 103) = 1 - 0.970 =0.03= 3\%

0.03 is  the probability that for the sample mean IQ score is greater than 103.
