----------------------------------------------------------------
Given information
----------------------------------------------------------------
x-intercept = -2 , therefore coordinate = (-2. 0)
y intercept = 3, therefore coordinate = (0, 3)

----------------------------------------------------------------
Find Slope
----------------------------------------------------------------
\boxed {Slope =  \frac{Y_2-Y_1}{X_2-X_1} }

\boxed {Slope =  \frac{3 - 0}{0 -(-2)} }

\boxed {Slope = \frac{3}{2} }

----------------------------------------------------------------
Substitute the slope and the y-intercept into the equation
----------------------------------------------------------------
y = mx + c
y = 3/2 x + 3

----------------------------------------------------------------
Answer : 3/2 x + 3

Rewrite the equation in Slope-Intercept Form. y+4=−12(x−2)
eimsori [14]

Answer: y = -12x +20

Step-by-step explanation: 1. distribute the -12 into the (x-2), that equals -12+24

2. subtract the 4 from the left side to move it to the right side of the equation

3. add like terms, so 24 + (-4) or 24-4 which equals 20.

4. Answer: y=-12x+20

Last school year, the student body of a local university consisted of 30% freshmen, 24% sophomores, 26% juniors, and 20% seniors
tino4ka555 [31]

Answer:

\chi^2 = \frac{(83-90)^2}{90} +\frac{(68-72)^2}{72}+\frac{(85-78)^2}{78}+\frac{(64-60)^2}{60} = 1.66

And the answer would be:

c. 1.66

Step-by-step explanation:

We need to conduct a chi square test

The statistic to check the hypothesis is given by:

\sum_{i=1}^n \frac{(O_i -E_i)^2}{E_i}

the observed values for this case are:

Freshemen=83

Sophomores=68

Juniors = 85

Seniors= 64

The expected values for this case are:

Fres_E =0.3*300= 90

Sop_E =0.24*300= 72

Jun_E = 0.26*300 =78

Sen_E = 0.20*300= 60

Then the statistic would be given by:

\chi^2 = \frac{(83-90)^2}{90} +\frac{(68-72)^2}{72}+\frac{(85-78)^2}{78}+\frac{(64-60)^2}{60} = 1.66

And the answer would be:

c. 1.66
