Answer:

-15

Step-by-step explanation:

4b - 3(6 + 2b) = 12

4b - 18 - 6b = 12

4b - 6b = 12 + 18

-2b = 30

b = 30/-2

b = -15

Evaluate y^2 + 2y for y = 0, 1, and 2. Are the resulting numbers prime or composite.
Elza [17]
Y = 0:
(0)^2+2(0)=0+0=0
0 is neither prime nor composite.

y=1:
(1)^2+2(1)=1+2=3
3 is a prime number (because only 3 and 1 divide evenly into it)

y = 2:
(2)^2+2(2)=4+4=8
8 is a composite number (because multiple different numbers divide evenly into it: 1, 2, 4, and 8)

Last school year, the student body of a local university consisted of 30% freshmen, 24% sophomores, 26% juniors, and 20% seniors
goblinko [34]

Answer:

1.66

Step-by-step explanation:

We need to conduct a chi square test

The statistic used to check this is given by the below

∑(n, 1) = [(O(i) - E(i)] / E(i)

From the question, we're told the observed value is

Freshmen

Sophomore

Junior

Senior.

After that, we then calculate the expected value.

Freshman

0.3 * 300 = $90

Sophomore

0.24 * 300 = $72

Statistics then finally gives us this

X² = (93 - 90²)/90 + (68 - 72)²/72 + (85 - 78)/78 + (64 -60)²/60

X² = 3² / 90 + 4² / 73 + 13² / 78 + 4² / 60

X² = 0.1 + 0.212 + 2.167 + 0.266 x+

X² = 2.745

X = √2.745

X = 1.66
