The infant mortality rate is deﬁned as the number of infant deaths per 1,000 live births. This rate is often used as an indicato

Basile [38]

(a)

Q1, the first quartile, 25th percentile, is greater than or equal to 1/4 of the points. It's in the first bar so we can estimate Q1=5. In reality the bar includes values from 0 to 9 or 10 (not clear which) and has around 37% of the points so we might estimate Q1 a bit higher as it's 2/3 of the points, say Q1=7.

The median is bigger than half the points. First bar is 37%, next is 22%, so its about halfway in the second bar, median=15

Third bar is 11%, so 70% so far. Four bar is 5%, so we're at the right end of the fourth bar for Q3, the third quartile, 75th percentile, say Q3=40

When the data is heavily skewed left like it is here, the median tends to be lower than the mean. The 5% of the data from 80 to 120 averages around 100 so adds 5 to the mean, and 8% of the data from the 60 to 80 adds another 5.6, 15% of the data from 40 to 60 adds about 7.5, plus the rest, so the mean is gonna be way bigger than the median of around 15.

Point c is the center of dilation. line segment b a is dilated to create line segment b prime a prime. the length of c a is 4. t

pychu [463]

The scale factor of the dilation of line segment ba for which the center of dilation is C, is 5.

<h3>What is the dilation of the figure?</h3>

Dilation of a figure, means the transformation of the figure. The factor by which the given figure dilated, called the scale factor of dilation.

Point c is the center of dilation. Line segment BA is dilated to create line segment b prime, a prime. The image of the given problem is attached below. The length of CA is 4.

$CA=4$

The length of a prime is 16.

$AA'=16$

The new dimension will be,

$CA'=CA+AA'\\CA'=4+16\\CA'=20$

Now, the scale factor is the ratio of the new dimension to the original dimension. Thus, the scale factor of the dilation is,

$r=\dfrac{20}{4}\\r=5$

This will be the same for the line segment BA. Thus, the scale factor of the dilation of line segment ba for which the center of dilation is C, is 5.

How do I get the ratio?

MA_775_DIABLO [31]

To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero).

A sludge pool is filled by two inlet pipes. One pipe can fill the pool in 10 days and the other pipe can fill it in 25 days. How

skad [1K]

9.28 days are taken to completely fill the pool

It is given that one pipe can fill the pool in 10 days

the other pipe can fill it in 25 days.

if no sewage is added, waste removal will empty the pool in 31 days.

The amount filled by pipe one in 1 day=1/10

The amount of pool filled by second pipe in 1 day=1/25

The waste removal pipe's work in 1 day= 1/31

Therefore, the work done together by all pipes in one day=1/10+1/25-1/31

= (775+310-250)/31*25*10=835/7750

Therefore, number of days taken to empty the pool= 7750/835=9.28 days

As half day cannot be counted, hence 9.28 days are taken to completely fill the pool

Disclaimer: The waste removal pipe has also been taken into consideration

If the perimeter of the triangle is 95 inches, what is the length of each side? n, 3n+8, and 4n+7.

IrinaVladis [17]

Answer: 10, 38, 47

Step-by-step explanation:

n + (3n + 8) + (4n + 7) = 95

8n + 15 = 95

8n = 80

n = 10

3(10) + 8 = 38

4(10) + 7) = 47
