154.35 - 10.37 = 143.98
143.98 - 27.83 = 116.15
10.37 = 116.15x
x = 0.0893
Change x to percent form to get 8.93% tax rate.
Answer:
97.3%
Step-by-step explanation:
Let the three bulbs be A, B and C respectively.
Let P(A) denote the probability that the first bulb will burn out
Let P(B) denote the probability that the second bulb will burn out
Let P(C) denote the probability that the third bulb will burn out
Now, we are told that Each one has a 30% probability of burning out within the month.
Thus;
P(A) = P(B) = P(C) = 30% = 0.3
Now, probability that at the end of the month at least one of the bulbs will be lit will be given as;
P(at least one bulb will be lit) = 1 - (P(A) × P(B) × P(C))
P(at least one bulb will be lit) = 1 - (0.3 × 0.3 × 0.3) = 0.973 = 97.3%
Answer:
79.17% probability that brandy will roll a strike the first frame of the next game
Step-by-step explanation:
The experimental probability is the probability based on previous outcomes, that is, the number of desired outcomes divided by the number of total outcomes.
While bowling with friends, Brandy rolls a strike in 57 out of 72 frames. What is the experimental probability that brandy will roll a strike the first frame of the next game?
Desired outcomes:
57 strikes
Total outcomes:
72 frames
Probability:
p = 57/72 = 0.7917
79.17% probability that brandy will roll a strike the first frame of the next game
Answer:
27
Step-by-step explanation:
If 6x-4 is 11 less than 25, what is the value of 9x can be rewritten as:
6x-4=25-11, what is the value of 9x?
Let's solve for x first by using the given information: 6x-4=25-11
1. 6x-4=25-11
2. 6x-4=14
3. (isolate x by adding 4 on both sides) 6x=18
4. x=3
The question asks for the value of 9x. Since we know x=3...
9x=9 times 3=27
9x=27
