<h3>
Answer: 99 and 88</h3>
=========================================================
Explanation:
The ratio of the two numbers is 9 to 8, which we can write as shorthand into 9:8
Multiplying both parts by x gets us the ratio 9x:8x where x is nonzero.
The numbers 9x and 8x add up to 187, so,
9x+8x = 187
17x = 187
x = 187/17
x = 11
Which then means
- 9x = 9*11 = 99
- 8x = 8*11 = 88
are the two numbers. Note how 9x+8x = 99+88 = 187 to help confirm the answers. Furthermore, note how 99:88 reduces to 9:8 after dividing both parts by the GCF 11.
Answer:
the answer is 120m 2 that your answer.
Using proportions, it is found that the actual cost of each pineapple is of $2.12
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, considering that the waste factor is of 15%, the<em> </em>total price<em> </em>should be of:
P = 0.85 x $14.95 = $12.7075.
For a case of 6 pineapples, hence the price of each is given by:
Pp = $12.7075/6 = $2.12.

Answer:
a) Normal Distribution
b) 0.146
c) 0.070
Step-by-step explanation:
We are given the following information in the question:
The number of accidents per week at a hazardous intersection varies with mean 2.2 and standard deviation 1.4
a) 
: mean number of accidents per week at the intersection during a year (52 weeks)
According to central limit theorem, as the sample size becomes larger, the distribution of mean approaches a normal distribution.
Since we have a large sample, the approximate distribution of is a normal distribution with
b) P(mean is less than 2)
Formula:
P(x > 610)
Calculation the value from standard normal z table, we have,
c) P(fewer than 100 accidents at the intersection in a year)
P(x < 100)
Calculation the value from standard normal z table, we have,
