I dont really know just guessing sorry im not smart. hope u find the answer doe:))

280

Step-by-step explanation:

So out of the 420 vehicles, 13.3% are SUVs. (56 divided by 420) You need to take 13.3% of 2100, which means 2100 x .133

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
