2 answers:

8 0

If the equation of a line is written in the $y=mx+b$ form, $b$ is the y-intercept.

$y=-6x-1 \\
b=-1$

The y-intercept is -1. The line crosses the y-axis at the point (0,-1).

What is the area of the figure down below

kogti [31]

68

Explanation:

So to get this answer you need to split it into smaller shapes. We already have the squares so we know that 3*3 is 9 and then we double that because there are two of them.

So, so far we have 18+x

We need to take the middle shape and split it into two trapezoids.

The area for trapezoids is T=(a+b/2)h

So T= (3+7/2)5
T= 5*5=25
And then we would double that because there are two of them so 50 and then fill it in for x
18+50= 68 is the area of the figure.

Find the slope and y-intercepts f(x)= -1/2x - 2

gavmur [86]

Answer:

slope: -1/2

y-intercept: -2

Step-by-step explanation:

f(x) = mx+b

m is slope

b is the y-intercept

if f(x) = -1/2x - 2

then

the slope or m is -1/2

and the y-intercept or b is -2

pickupchik [31]

Answer:

C) 3.03

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 50

The Mean of the population (μ) = 62

The standard deviation of the Population (σ) = 7

Mean of the sample(x⁻) = 65

Z-score

$Z= \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }$

Step(ii):-

$Z= \frac{65 -62}{\frac{7}{\sqrt{50} } }$

Z = 3.03

Final answer:-

The Z-score = 3.03
