I’m having this weird math issue, I’ve tried to find the right answer and even used a calculator but didn’t get it correct?

-2

Step-by-step explanation:

You first get the sqrt for everything.

64-25•2

3-10

Then multiply the 25 and 2 first because of PEMDAS.

So

64-50

3-10

Then subtract from both top and bottom.

14/-7

Then divide.

-2

Hope this helps

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.
