Subtract the sum of -1250 and 1138 from the sum of 1136 and 1272

Let’s organize what they’re asking for.

Subtract the sum of -1250 and 1138 from the sum of 1136 and 1272.

Lets first find the sun if -1250 and 1138:

-1250 + 1138 = -112

Then we’re asked to subtract that sum from the sum of 1136 and 1272. So now let’s find the sum of 1136 and 1272:

1136 + 1272 = 2408

Alright now back to what they’re asking for.

The question asks to subtract the sum of -1250 and 1138 FROM the sum of 1136 and 1272.

We’re subtracting a negative number FROM a positive number, so basically we can turn the negative number into a positive number and we will instead have an addition problem:

2408 - (-112)

The -112 will change to a +112

so now we have an addition problem.

2408 + 112 = 2520

The answer to your question is 2,520

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.
