Kevin calculated the product of 3.2 x 104 and 3.6 102 as 11.52 x 106 Which is the next step that Kevin should
apply to his solution?
Write in scientific notation, moving the decimal in the coefficient one place left and keeping the same exponent,
O Write in scientific notation, moving the decimal in the coefficient one place to the left, which subtracts 1 from the
exponent value
Write in scientific notation, moving the decimal in the coefficient one place to the left, which adds 1 to the
exponent value
o Write in scientific notation, moving the decimal in the coefficient one place to the right, which adds 1 to the
exponent value
Intro
Done

C, Write in scientific notation, moving the decimal in the coefficient one place to the left, which adds 1 to the exponent value.

Step-by-step explanation:

I'm not sure how to explain it, but i'm pretty sure if you don't move the decimal to the left it wouldn't be in simplest form or scientific notation???

A is the wrong choice because it makes no sense

B is wrong because if you take remove a decimal place you need to add 1 to the exponent value

C is correct

D is wrong because if you move it one place to the right you would need to take away from the exponent value

C

Step-by-step explanation:

I was just on the question and the correct answer was C. or

Write in scientific notation, moving the decimal in the coefficient one place to the left, which adds 1 to the exponent value.

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.
