what is the coordinate of the vertex of the parabola y-2=1/12(x+10) a. ( 10,-2) b. (-10,2) c. (-2,10) d. (2.-10)

With the vertex

We see that b = -10 and a = 2 and then the vertes wuld be:

And the best option is:

b. (-10,2)

Step-by-step explanation:

For this problem we have the following function:

And if we compare this expression with the general expression for a parabola given by:

With the vertex

We see that b = -10 and a = 2 and then the vertes wuld be:

And the best option is:

b. (-10,2)

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.
