9.60 (.25) = 2.40
9.60 - 2.40 = 7.20
25% of $9.60 is $2.40, so the bottle would be $7.20
The cat will weigh 201 ounces since 12*16+9=201 ounces
Answer:
The mean will stay the same.
The standard deviation will decrease.
Step-by-step explanation:
For the 5 cards, she has received, the mean will be:
μ=(∑x)/n
=125/5
=25
The mean is 25 and the standard deviation is 10.
σ=10
If a new card is received with $25, then the sum will be $150
So the new mean will be:
μ'=(∑x)/n
=150/6
=25
And the new standard deviation will be:
σ'= 9.12
We can clearly see that
μ= μ'
and
σ> σ'
So the mean will remain the same and standard deviation will decrease.

The term that best describes two events that together include all outcomes in the sample space is complementary.
Answer:
x^3/7
Step-by-step explanation:
In exponential form the number on the outside of the √ will be the denominator of the fraction.
