Alright, lets get started.
The quantity of the shampoo Jill always buys = 11.5 ounce
She is at the store buying more and sees that the bottle is now bigger and has 20% more for the same price.
Means we could find the extra shampoo she is getting by :
ounce
Means she is getting total shampoo in her new bottle =
Means she is getting total shampoo in her new bottle = 13.8 ounce : Answer
Hope it will help :)
It’s 16, you get the answer by counting the outside ones
Answer:
9
Step-by-step explanation:
The mean squared error (MSE)of a set of observations can be calculated using the formula :
(1/n)Σ(Actual values - predicted values)^2
Where n = number of observations
Steps :
Error values of each observation (difference between actual and predicted values) is squared.
Step 2:
The squared values are summed
Step 3:
The summation is the divided by the number of observations
The difference between the actual and predicted values is known as the ERROR.
(1/n)Σ(ERROR)^2
n = 3
Error = +3, +3, - 3
MSE = (1/3)Σ[(3)^2 + (3)^2 + (-3)^2]
MSE = (1/3) × [9 + 9 + 9]
MSE = (1/3) × 27
MSE = 9
Answer:
A. Approximately 2000 times the mass of an electron.
Step-by-step explanation:
Lets do the division:
Mass of neutron / mass of electron
2 × 10^-24 / 9 x 10^-28
= 0.222 x (10^(-24 - (-28))
= 0.2222... x 10^4
= 2222.
2x+8y in factor form is 2(x+4y)
