You always start by simplifying.
6b-49=2<span>(</span>b-3) becomes 6b-49=2b-6
From there you can group the b's together by subtracting 2b from both sides, leaving you with 4b-49=-6
Now you can get the b's alone by adding 49 (to cancel out -49) to both sides, giving you 4b=43, You're still trying to get b by itself, so what you'll do is divide both sides by 4, giving you b=10.75

Answer:
31.4 in
Step-by-step explanation:
I must assume that you meant "10-inch pizza," which implies a diameter of 10 inches. The formula for the circumference of a circle when the diameter is known is C = πd , so here:
C = π(10 in) = 10π in, or roughly 31.4 in.
Answer and Explanation:
Her alternative hypothesis is that there is some difference between the means of the ages of the audiences of the two television programs. That is, the mean ages of the two audiences are not the same.
If the mean of the ages of the audiences of television programme 1 (COPS) is xbar₁
And the mean of the ages of the audiences of the television programme 2 (60 minutes) is xbar₂
Her alternative hypothesis can be represented mathematically as
xbar₁ - xbar₂ ≠ 0
Answer:
This means that the coach should have the team going for the 2 point shot. There is a 36% probability of making the 2 point shot and winning overtime.
Step-by-step explanation:
We have these following probabilities:
A 60% probability of tying the game on a 2 point shot. In this case, the game goes to overtime, in which the team has a 60% probability of winning.
A 30% probability of making the 3 point shot and winning.
What should the coach do, go for the 2 point shot or the 3 point shot?
In which case the team has a higher probability of winning?
The team has:
A 60% probability of tying the game on a 2 point shot. In this case, the game goes to overtime, in which the team has a 60% probability of winning. So, going for the 2 point shot, the team has a 0.6*0.6 = 0.36 = 36% probability of winning.
Going for the 3 point shot, the team has a 30% probability of winning.
This means that the coach should have the team going for the 2 point shot. There is a 36% probability of making the 2 point shot and winning overtime.
