$\displaystyle\bf\\ \text{\bf The slope = }~~\frac{y_2-y_1}{x_2-x_1}=\frac{4-(-4)}{4-(-1)}=\frac{4+4}{4+1}=\boxed{\bf\frac{8}{5}}$

Scorpion4ik [409]

Answer: a = 8

Step-by-step explanation:

use the equation a^2 + b^2 = c^2

c = 17, b = 15

a^2 + 15^2 = 17^2

a^2 + 225 = 289

a^2 = 64

a = 8

JOSE SAID ALL OF THE MULTIPLES OF 8 ARE ALSO MULTIPLES OF 2. JAMILA SAID THAT ALL OF THE MULTIPLES OF 8 ARE ALSO MULTIPLES OF 4

Dimas [21]

2 and 4 are both factors of 8, which means any multiple of 8 can be divided by both 2 and 4 since 8 can be. So, Jose and Jamila are both right.

The shape of the distribution of the time required to get an oil change at a 10 minute oil change facility is unknown. However,

lyudmila [28]

Answer:

The answer is below

Step-by-step explanation:

a) For a normal model the sample size has to be equal or greater than 30 so that it can be a normal distribution.

b) Given that:

μ = 11.2 minutes, σ = 4.8 minutes, n = 45

The z score determines how many standard deviations the raw score is above or below the mean. It is given by:

$z=\frac{x-\mu}{\sigma} \\For\ a\ sample\ size(n)\\z=\frac{x-\mu}{\sigma/\sqrt{n} }$

For x < 10 minutes

$z=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\ z=\frac{10-11.2}{4.8/\sqrt{45} }= -1.68$

Therefore from the normal distribution table, P(x < 10) = P(z < -1.68) = 0.0465
