Answer:
$100
Step-by-step explanation:
149-49=100
Answer:
$11.22
Step-by-step explanation:
100% = 187
1% = 187/100 = $1.87
6% = 1%×6 = 1.87×6 = $11.22
Answer:
The scale factor is k = 1/30
a)
<u>The length of the wing on the model:</u>
- 9 m * 1/30 = 900 cm * 1/30 = 30 cm
b)
<u>The area of the tail section of the plane:</u>
- 80 cm² : (1/30)² =
- 80 cm² * 900 =
- 72000 cm² =
- 72000 * (1/100)² m² =
- 7.2 m²
Answer:
115
Step-by-step explanation:
PKL=180-JKP
= 180-65
=115°
Using the normal distribution, it is found that 0.13% of American women CANNOT use the bicycles designed by this company.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:

The proportion of women that cannot use the bikes(smaller than 54.5 inches) is the <u>p-value of Z when X = 54.5</u>, hence:


Z = -3
Z = -3 has a p-value of 0.0013.
0.0013 = 0.13% of American women CANNOT use the bicycles designed by this company.
