The probability of one woman to have height less than 64.4 in is 0.6293
<u>Explanation:</u>
Given:
Mean, μ = 64.4
Standard deviation, δ = 1.8
Probability that the height of the woman is less than 65 inch = ?
So,
P(x < 65) = 65 - μ / δ
P (x < 65) = P( z < 0.33)
Finding the probability value from the z table we get:
P( z < 0.33) = 0.6293
Therefore, the probability of one woman to have height less than 64.4 in is 0.6293

1. FIRST QUESTION.</h2>
M is directly proportional to
Suppose you have two variables, say, . We say that varies directly as or, in other words, is directly proportional to if and only if:
Where is a nonzero constant called the constant of proportionality.
Knowing this, we can solve this problem. Here is directly proportional to . So:
We know that when , hence the constant of proportionality can be found as follows:
So:
<h3>PART A)</h3>
When , then:
<h3>PART B)</h3>
When , then:
<h2>2. SECOND QUESTION.</h2>
M is directly proportional to
We know that when , hence the constant of proportionality is:
So:
<h3>PART A)</h3>
When , then:
<h3>PART B)</h3>
When , then:
A scale of 8cm:12cm would be a scale of 2/3. since this is the case, we can divide the scale drawing of the playground by the scale factor to get the length of the actual playground
12.4/0.6666 = 18.6
The answer is 18.6
Answer:
(600 mi) × (5280 ft/mi) × (12 in/ft)
Step-by-step explanation:
A "unit multiplier" is a multiplier that has a value of 1. That is, the numerator and denominator have the same value. For units conversion problems, the numerator quantity has the units you want, and the denominator quantity has the units you're trying to cancel.
You have units of miles. You know that ...
1 mile = 5280 feet
1 foot = 12 inches
You want to get to units of inches. With these conversion factors, you can do it in two steps (as the problem requests). The first conversion is from miles to feet using the unit multiplier (5280 feet)/(1 mile). This gives you a number of feet.
Then the second conversion is from feet to inches, so you use the one that lets you put inches in the numerator and feet in the denominator:
(12 inches)/(1 foot)
When you multiplie these all out, units of miles and feet cancel, and you're left with inches.
_____
With the above conversion factors, you can write unit mulipliers of either ...
(5280 ft)/(1 mi) . . . to convert to feet
or
(1 mi)/(5280 ft) . . . to convert to miles.
