Answer:
1.90
Step-by-step explanation:
You would want to use a calculator since you need decimal places.
Once you type it into the calculator you should get 1.8952380952.
Since you're trying to simplify to the second decimal place, look at the third number after the decimal.
The 5 rounds up the 9 to a ten, which is represented by the 0.
That then turns the 8 into a nine.
Answer:
Yes, the events silver and black are mutually exclusive.
Step-by-step explanation:
We are given;
the probability that car was mainly white;P(W) = 0.24
the probability that it was mainly silver;P(S) = 0.22
the probability that it was mainly black; P(B) = 0.19
We can say that while a car can certainly be black and silver, a car cannot be mainly silver and mainly black at the same time. This is because one color is going to be dominant. Thus, they cannot happen at the same time. We can therefore conclude that;
Yes, the events silver and black are mutually exclusive.
Answer:
Step-by-step explanation:
So Blakes sleep 8 hours per night during the school day
8 hours/night...................................100%
6.5 hours/night...................................?
6.5*100/8=81.25
the change in percentage is 100-81.25=18.75%
the percentage change is 18.75
if it is easier for you, another method is:
8-6.5=1.5 subtract the original amount to the new amount
1.5/8=0.1875 divide by the original amount
0.1875*100=18.75 find the percentage
They can travel roughly 110 miles for 5 gallons of gas.
Here is the factored polynomial
(x^2+9)(x^2-3x-9)=0
