Step-by-step explanation:

Square root means that the number that if you divide it. The number that if you divide it. The number you get multiply it self, will give you the answer. 8 doesn't have a square root, because 2×2= 4,4×4= 16.so 8 doesn't have a square root. But 9 has. 1×1= 1,2×2= 4,3×3= 9.Square root of 9 is 3

Is the distance a baseball travels in the air after being hit a discrete random variable, a continuous random variable, or not

LuckyWell [14K]

Answer: a continuous random variable

Step-by-step explanation:

Can you count the distance it traveled? You can't, so it couldn't be discrete because you can count discrete variables.

Can you measure the distance it traveled? You sure can, that makes it a continuous random variable.

Do you know the exact distance it's going to travel? You won't, therefore it's a random variable since you don't know the value beforehand.

Activity paper to answer

PIT_PIT [208]

Answer:

a) 5cm

b) 16cm

c) 25cm

d) 124cm

a) 4m

b) 6m

c) 10m

d) 26m

a) 2km

b) 4km

c) 11km

d) 28km

Step-by-step explanation:

When you have a number and it tells you to round it to the nearest cm (m, km etc.), it means you just have to make it a whole number (integer) instead of a decimal by rounding it up or down.

To tell whether you round up or down, you look at the number after the decimal place and if it is under 5, you round down but if it is 5-9 you round up.

For example,

If we had 20.3 (not one of the questions) you would round it down to 20 because the 3 after the decimal place is smaller than 5.

However, if we had 24.7 you would have to round it up because the 7 is from 5-9.

Hope this helps :)

Charles has eight different winter scarves, and he wears three at a time. How many different ways can Charles wear three scarves

jenyasd209 [6]

Answer:

Ans= 6720 ways

Step-by-step explanation:

From Combination rule from Permutation and Combination, nCr

We use 8^C3 or 8C3,

8x7x6x5x4x3x2x1

-------------------------- =6,720

3x2x1

8x7x6x5x4x3! /3!, here the 3! cancels each other out, and we're left with 8x7x6x5x4, which equals 6720.
