Answer:

24 38%

25 17.04%

26 53%

Step-by-step explanation:

Q24

L = MN

M becomes 1.15M; N becomes 1.2N

L = (1.15M)(1.2N)

L = 1.38MN

L was MN; now L is 1.38MN

Answer: The percent increase in L is 38%

Q25

A = bh/2

A = 0.5ab

a becomes 1.33a; b becomes 0.88b

A = (1.33a)(0.88b)/2

A = 0.5852ab

The area increased from 0.5ab to 0.5852ab.

0.5852/0.5 = 1.1704

Answer: The percent increase in area is 17.04%

Q26

30% of members are male

70% of members are female

Male training for marathon: 60% of 30% = 18%

Female training for marathon: 50% of 70% = 35%

Total: 18% + 35% = 53%

Answer: 53%

Let a population consist of the values cigarettes, cigarettes, and cigarettes smoked in a day. Show that when samples of size

Katen [24]

The "sample" with "mean absolute deviation" indicate about a sample mean absolute deviation is being used as an estimator of the mean absolute deviation of a population

Mean of the sample MAD=3.3
Population MAD =6.4

<h3>What does this indicate about a sample mean absolute deviation used as an estimator of the mean absolute deviation of a population?</h3>

Generally, The MAD measures the average dispersion around the mean of a given data collection.

$1/n \sum_i-1^{n} |x_i -m(X)|$

In conclusion, for the corresponding same to mean

the sample mean absolute deviation

7,7 ↔ 0

7,21 ↔ 7

7,22 ↔ 7.5

21,7 ↔ 7

21,21 ↔ 0

21,22 ↔ 0.5

22,7 ↔ 7.5

Therefore

Mean of the sample MAD=3.3
Population MAD =6.4

Write the point-slope form of the line that passes through (-8, 2) and is perpendicular to a line with a slope of -8

Schach [20]

Answer:

y - 2 = (1/8)(x + 8)

Step-by-step explanation:

The slope of the given line is -8. That means the slope of any line perpendicular to the given line will be the negative reciprocal of -8, which would be (1/8).

Then the desired equation is

y - 2 = (1/8)(x + 8)

2.Choose an even number to use yourself. Ask your friend to add this number to the one in his head.
3.Tell him/her to divide the new number by 2.
4.Tell your friend to subtract his original number from the equation.
5."Guess" the number.

C.) 4. Solve the system of equations

raketka [301]

You can set them equal to each other so -3x+4=4x-10 and then you add 3x and 10 on both sides and get7x=14 and then divided both sides by 7 and get x = 2 and check by plugging in and you get -2 for y on both so solution is x=2

What is the sum of the first five terms of a geometric series with a1=15 and r=1/3

Solnce55 [7]

Answer:

15, 5, 5/3, 5/9, 5/27

Step-by-step explanation:

Recall, that the general form of a geometric series is

a, ar, ar², ar³, .........

where a is the first term and r is the ratio

It is given that the first time is 15, hence a = 15

also given that ratio is 1/3

hence the first 5 terms are:

15, (15)(1/3), (15)(1/3)^2, (15)(1/3)^3, (15)(1/3)^4

simplifying each term gives

15, 5, 5/3, 5/9, 5/27
