How do u work out a whole number multiplied with a decimal

1 answer:

6 0

If you want to multiply a decimal by a whole number, just ignore the decimal point and multiply like normal! Then, bring the decimal point back for the answer. for example 2×0.2

first multiply 2*2=4

and then place the decimal we have one value after decimal so the answer is 0.4

Rory is staying in a cabin on a hill 300 feet above sea level. She walks down the hill to the water’s edge. The equation of her

Anastasy [175]

For this problem, we plug in the numbers for t and the appropriate letters for e to the equation e = 300 - 10t.

a) a = 300 - 10(-2)

simplify: a = 300 + 20

simplify: a = 320 ft.

But, this is not a viable point because when t≤0, she doesn't move anywhere, thus, should consistently be 300 ft.

b) b = 300 - 10(3.5)

simplify: b = 300 - 35

simplify: b = 265 ft.

c) c = 300 - 10(30)

simplify: c = 300 - 300

simplify: c = 0 ft.

The average test score of the class was an 80 and the standard deviation was 2. About 99% of the class would score between what

Alisiya [41]

Answer:

Answer: 78 and 82.

Step-by-step explanation:

We have been given that the average test score of the class was an 80 and the standard deviation was 2. We are asked to find two values between which 68% of class will score.

We know that in a normal distribution approximately 68% of the data falls within one standard deviation of the mean.

So 68% scores will lie within one standard deviation below and above mean that is

Upon substituting our given values, we will get

Therefore, about 68% of the class would score between 78 and 81 and option B is the correct choice.

Step-by-step explanation: Hope this helps :D
