SOMEONE HELP ME PLEASE! I’m trying to do my homework and this is hard! It’s linear functions. Also it’s number 3

kondaur [170]

Answer:

A. y = 1x + 4

B. 1

C. 4

Step-by-step explanation:

The point (0, 4) is the y-intercept. So b = 4

y goes up each time by 1. So m = 1

Plug into y = mx + b

y = 1x + 4

The mean and standard deviation of a normal distribution are 150 and 12 respectively. What percentage of values lie between:

Semenov [28]

Answer:

Step-by-step explanation:

Use a calculator with built-in statistical functions. The function applying here is normcdf(, the "cumulative density function."

(a) The percentage of values lying between 138 and 162 is

norm(138,162, 150, 12), which comes out to 0.683, or 68.3%.

(b) Find norm(126, 174, 150,12): 0.945, or 94.5%

(c) Find norm(126,162, 150,12); 0.819, or 81.9%

(d) Find norm(162, 174,150,12): 0.136, or 13.6%

Use the slope formula to find the missing coordinate: R(0,_), S(-4,2) m=5

Delicious77 [7]

Answer

The missing value is 22

step-by-step explanation

The slope formula is

$m = \frac{y_2 - y_1}{x_2 - x_1}$

From the question,

m=5

$x_2=-4$

$y_2=2$

and

$x_1=0$

We substitute these values to get,

$5= \frac{2 - y_1}{ - 4- 0}$

Simplify

$5= \frac{2 - y_1}{ - 4}$

$5 \times - 4=2 - y_1$

$- 20=2 - y_1$

$- 20 - 2=- y_1$

$22= y_1$

$y_1 = 22$

The missing value is 22
