the width of a rectangle is three fourths of the length. The perimeter of the rectangle becomes 50cm when the length and width are increased by 2cm. Find the length and the width.

Answers

remember
P=2(l+w)
w=wdith
l=legnth
w is 3/4 legnth
w=3/4l

P=50 when l+2 and w+2

so
50=P=2(l+2+w+2)
w=3/4l, so sub
50=2(l+2+3/4l+2)
divide everybody by 2 to ge rid of nasty parenthasees
25=l+2+3/4l+2
25=1 and 3/4l+4
minus 4
21=1 and 3/4l
21=7/4l
times 4 both sides
84=7l
divide by 7
12=l
sub
w=3/4l
w=3/4(12)
w=9

legnth=9
width=12

then length=12
Width=3/4 of x
= 3/4 * 12
= 9
the answer is 9

A math teacher’s midterm is worth 200 points. The mean of the test is 143 and the standard deviation is 15.7. If the scores have a bell shaped distribution, what percentage of the scores are between 111.6 and 174.4?A. About 99.7%
B. About 68%
C. About 62.8%
D. About 95%

Answers

If the scores have a bell shaped distribution, percentage of the scores are between 111.6 and 174.4 would be D. About 95%

How to find the percentage ?

The given values 111.6 and 174.4 are one standard deviation away from the mean

= 143 - 15.7 = 127.3

and

143 + 15.7 = 158.7

So 111.6 and 174.4 are even farther away from the mean.

In a bell-shaped distribution (normal distribution), about 68% of the data falls within one standard deviation of the mean, about 95% falls within two standard deviations, and about 99.7% falls within three standard deviations.

Since 111.6 and 174.4 are more than one standard deviation but less than two standard deviations from the mean, the percentage of scores between 111.6 and 174.4 would be about 95%.
