Answer:
13
Step-by-step explanation:
25 can go into 325 13 times
( 25 X 4 = 100 ) ( 25 X 4 = 100 ) ( 25 X 4 = 100 )= 300 + . 25
4 4 4 . =12 (25)= 1
12+ 1 = 13
The rule is to subtract 6
<u>Answer:</u>
Rhonda will not fall 264 times in 360 jumps.
<u>Solution:</u>
Given, The ratio of jumps to falls for ice skater Rhonda is 4 falls to every 15 jumps.
We have to find At this rate, how many times will she not fall in 360 jumps.
Now,
For 15 jumps → 4 falls
For 360 jumps → n falls
Now apply Chris cross method,
So, she falls 96 times in 360 jumps.
Then, number of times she will not fall = 360 jumps – 96 falls = 264 times.
Hence, Rhonda will not fall 264 times in 360 jumps.
Answer:
0.39 = 39% probability that 4 adults selected at random from the town all have health insurance
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they have health insurance, or they do not. The probability of an adult having health insurance is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In one town, 79% of adults have health insurance
This means that
4 adults
This means that
What is the probability that 4 adults selected at random from the town all have health insurance?
This is P(X = 4).
0.39 = 39% probability that 4 adults selected at random from the town all have health insurance
