Answer:

AX : XB as AB : AC

AX = 5

XB = 4

AC = 6

AB = x

Step-by-step explanation:

5 : 4 as to x : 6

ratios can also be written as fractions...

5/4 = x/6 ..now we have a proportion...so we cross multiply

(4)(x) = (5)(6)

4x = 30

x = 30/4

x = 15/2 <==== AB = 15/2

Answer:

152 men, 76 women, and 38 children

Step-by-step explanation:

Children- x

Women-2x

Men-4x

4x+2x+x=266

7x=266

x=38

2x=76

4x=152

152 men, 76 women, and 38 children

Answer:

8

Step-by-step explanation:

The data set up lowest to highest is: 6, 8, 8, 14, 18. Median is the middle number of the data, so the answer would be 8

Answer:

Step-by-step explanation:

21

Answer:

x=8

Step-by-step explanation:

The formula for the area of a kite is pq/2. In this case, 15 inches is p and x is q. Since the answer is being divided by 2, you want pq to be double the actual area. 60 times 2 is 120. 120 divided by 15 is 8. Therefore, x is equal to 8.

You can check this answer by substituting the values intothe equation.

(15)(8)/2= 120/2= 60.

Answer:

Step-by-step explanation:

Two groups of subjects were divided in an experimental study. One group was given a drug to help speed up

their metabolism and result in weight loss. The other group was given a placebo (a pill that looks identical to the one given to the other group, but without the weight loss drug). After a month of the experiment, the weight loss of each individual in each of the two groups were measured. In general, people in the group who took the metabolism drug did lose more weight, although there were differences in the amount each lost. There are two main types of variability occurring in this study. Describe each type below in the context of this study.

Induced Variability-

Natural Variability-

------------------------------------------------------------------------

Induced Variability - It is the kind of variability that is introduced by the one conducting the experiment. The decision to give one group the drug and othe other group a placebo was deliberate to check the merit of the drug on its own and was introduced by the one conducting the study. Hence the, the observation that the group that took the drug lost more weight as compared to the group that took the placebo is an induced variability.

Natural Variability - It is classified as a natural fluctuation in the observations that is not influenced by the one conducting the study. Even though the group that took the drug lost more weight, the exact amount that each of them lost was not constant. Hence this was a variability that did not introduce itself through the one conducting the study, and rather was unexplained and natural. Hence it is a natural variability.

The formula for area of a circle is r² x π.

Since we know the diameter, we can firstly divide by 2 to find our radius.

4/2 = 2

Now that we know the radius, we can substitute it in and square the value.

(2)² x π

(4) x π

Since we're finding the area in terms of pi, we won't multiply by pi, giving us the answer of 4π.

Therefore, the area of the circle is equal to 4π.

Hope this helped! :)

Answer:

If the diameter of the circle is 4 in. then the radius of the circle is 2

the formula for the circle area is

A = πr^2

r = radius

A = π * 2 * 2

A = 12.57 if solved

Answer:

n<38

Step-by-step explanation:

n – 96 < –58

Add 96 to each side

n – 96+96 < –58+96

n<38

Answer:

4th answer is correct

Step-by-step explanation:

n - 96 < - 58

Add 96 to both sides.

n - 96 + 96 < - 58 + 96

n < 38

Answer:

x = 81

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle, thus

x = 23 + 58 = 81

Answer: 176

Step-by-step explanation:

To evaluate the equation we have to remove the parentheses and add 15 + 17...

1/2 (11)(15 + 17) =

= 11 * 32 * 1/2

Now, we have to turn it into a fraction and multiply it...

[tex]\frac{1*11*32 }{2}[/tex]

= [tex]\frac{352}{2}[/tex]

352 ÷ 2 = 176

Answer:

your answer is -9,-4,0,2,7 so your answer is d

Step-by-step explanation:

by looking on the number line you can see that -9 is farthest to the left ,so meaning it would go first and 7 which is the farthest right meaning it should be last giving you the order -9 as first -4 as second and 0 as third and so on.

Answer:

as the sign of coordinates of different ordered pairs is as shown in the diagram so

ans. to 1 is quadrants one and three

ans. to 2 is quadrants two and four

Answer:

Step-by-step explanation:

The box plot shows all three quartiles, where the first one is 45, the second quartile is 50 and the third quartile is 67 (remember that there are only three quartiles in a dataset).

Now, the interquartile range is defined as the difference between the third and first quartile, which in this case is 67 - 45 = 22.

Therefore, the interquartile range is 22.

Good luck on your assignment

Answer:

No solution

Step-by-step explanation:

The given equation is,

→ w + (3/4) = w - (2/2)

Now we have to,

→ Find the required value of w.

Then the value of w will be,

→ w + (3/4) = w - (2/2)

Finding LCM in both sides:

→ (4w/4) + (3/4) = (2w/2) - (2/2)

→ (4w + 3)/4 = (2w - 2)/2

Cross multiplying both sides:

→ 2(4w + 3) = 4(2w - 2)

Applying Distributive property:

→ 2(4w) + 2(3) = 4(2w) - 4(2)

→ 8w + 6 = 8w - 8

→ 8w - 8w = -8 - 6

→ [ 0 = -14 ] => {No solution}

Hence, it has no solutions.

Answer:

40.186 Mb

Step-by-step explanation:

14.2% of 283 megabytes have been downloaded.

To find a percent of a number, multiply the percent by the number. Change the percent to a decimal by dividing the percent by 100 which means move the decimal point of the percent two places to the left.

14.2% of 283 Mb =

= 14.2% * 283 Mb

= 0.142 * 283 Mb

= 40.186 Mb

Answer: 40.186 Mb
