Answer:

9:14

Step-by-step explanation:

If the ratio of girls to students is 5:14, that means there are 9 boys for every 5 girls. Therefore, the ratio of boys to students is 9:14.

Answer:

9

Step-by-step explanation:

Girls = 5 out of 14

So, ratio of girls to total strength is 5:14

Boys = 14-5 = 9 boys

So, ratio of boys to total strength is 9:14

Ratio of boys is 9

Answer: Can't see the questions clearly, also  3/4 x 1/3 is 1/4

Step-by-step explanation:

Answer: x = 10

Step-by-step explanation:

Let's say that the unknown is x.

{2/5 = ?/25}

Step 1. 2/5 = x/25

Step 2. Multiply by 25 on both sides. 2/(5 * 25) = x/(25 * 25)

Step 3. 2 * 5 = x

Step 4. 10 = x

Step 5. Let's check the answer x; 2/5 = 10/25

Step 6. Simplify; 2/5 = (10/5) / (25/5)

Step 7. Check; 2/5 = 2/5

This answer is true

Answer:

The required height of the lighthouse is given as 160 ft tall.

Given that,

A scale model of a lighthouse has a scale of 1 in. : 8 ft. The scale model is 20 inches tall.

What is the scale factor?

The scale factor is defined as the ratio of the modified change in length to the original length.

What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

here,

scale factor = 1 / 8 in per ft

Now,

The actual length of the lighthouse =  20 / [1 / 8]

                                                            = 20 × 8 = 160 ft

Thus, the required height of the lighthouse is given as 160 ft tall.

Step-by-step explanation:

Since [tex]4^2 + 4^2 = (4\sqrt{2})^2[/tex], the angle formed by the sides is a right angle. Therefore, the garden is not a square.

The Pythagorean Theorem states that for a right triangle, the length of the hypotenuse squared is equals to the sum of the squared lengths of the sides of the triangle.

For this problem, we have that:

Applying the Pythagorean Theroem, the equality [tex]4^2 + 4^2 = (4\sqrt{2})^2[/tex] hold true, meaning that the triangle is in fact a right triangle.

(1) The mean absolute deviation for the given data set is 18.

The mean absolute deviation (MAD) is a way of measuring of data variability that is defined as the average of each data point's absolute deviation from the mean. To calculate the MAD, first compute the mean of the data set, then subtract each data point from the mean and calculate the absolute value of the result.

Here is the step-by-step process for finding the MAD for the given data set:

Find the mean of the data set: (108 + 53 + 47 + 22 + 56 + 62) / 6 = 56

Subtract the mean from each data point:

108 - 56 = 52

53 - 56 = -3

47 - 56 = -9

22 - 56 = -34

56 - 56 = 0

62 - 56 = 6

Take the absolute value of each result:

|52| = 52

|-3| = 3

|-9| = 9

|-34| = 34

|0| = 0

|6| = 6

Find the average of the absolute deviations: (52 + 3 + 9 + 34 + 0 + 6) / 6 = 18

So, the mean absolute deviation for the given data set is 18.

(2) The mean absolute deviation for the given data set is 2.7

Find the mean of the data set: ( 12.2 + 6.8 + 3.4 + 8.8 ) /4 = 7.8

Subtract the mean from each data point:

12.2 - 7.8 = 5.4

6.8 - 7.8 = - 1

3.4 - 7.8 =  - 4.4

8.8 - 7.8 = 1

Take the absolute value of each result:

|4.4| = 5.4

|-1| = 1

|-4.4| = 4.4

|1| = 1

Find the average of the absolute deviations: (5.4+ 1 + 4.4 + 1) / 4 = 2.95

So, the mean absolute deviation for the given data set is 2.95.

Answer:

Step-by-step explanation:

divide by 6

2k+8=-8

subtract 8 in both sides

2k=-16

divide by 2

k=-8

equal to -8

In order to solve for k you always want to try and isolate the variable (trying to get only k on one side of the equal sign). You can start of by distributing 6 into the numbers in the parenthesis. So 6 times 2k is 12k and 6 times 8 is 48. So in reality, you now have 12k+48= -48. Then you can subtract 48 from the left side to cancel it out. Note: you would not add 48 to cancel out the -48 on the right because you need a number on both sides of the equal sign. So once you subtract -48 from one side you must do it to the other so -48-48 is -96. Now you have 12k=-96. All you have to do now is cancel out the 12k but dividing since it is the inverse of multiplying. Divide 12 from both sides and -96 divided by 12 is -8.

So your answer is k=-8

(1) Total No of families = 1500

Total No of families with 2 girls = 475

Probability of family being chosen at random having 2 girls = 475/1500 = P1 = 19/60

(2) Total No of families = 1500

Total No of families with 1 girl = 814

Probability of family being chosen at random having 1 girl = 814/1500 = P2 = 407/750

(3) Total No of families = 1500

Total No of families with no girl = 211

Probability of family being chosen at random having no girls = P3 = 211/1500

(4) P1 + P2 +P3

Question 1: P = 35 degrees

It is given to us that angles N and P are complementary.

Complementary angles means the sum of the angles = 90 degrees.

Because angles N and M are supplementary, meaning they = 180 degrees, you can subtract angle M from 180.

180 - M = N

180 - 125 = 55

N = 55 degrees

Now that we know N = 55 degrees, we subtract that from 90 degrees to find P for N + P = 90 degrees, so if we subtract 55 from 90 we will get the value of angle P.

90 - N = P

90 - 55 = 35

P = 35 degrees!

Question 2: Option 4

We are trying to figure out which angles are congruent to one another.

We can rule out option one, for angles 1 & 4 are supplementary meaning their sum = 180 degrees.

The same applies for options 2 & 3, leaving us with the correct answer, option 4. We can make sure this is true because angles 3 & 5 are alternate interior angles, and alternate interior angles of parallel lines are congruent.

Question 3: x = 5

The three different angles add up to 180 because they are a straight angle.

First, we need to find out what 9 and 10 are equal to.

To do so, we can subtract 85 from 180.

180 - 85 = 9x + 10x

9x + 10x = 95

Now that we have an equation, we can simplify to find the value of x.

9x + 10 = 95

19x = 95

Divide by 19 on each side to isolate the variable x

x = 5

Answer:

angle FDE = 44 degrees

angle DEF = 66 degrees

angle FHG = 44 degrees

angle CDE = 63 degrees

angle BCE = 105 degrees

Step-by-step explanation:

first image

2x + 3x = 110

5x = 110

x = 22

angle FDE = 2x = 2(22) = 44

angle DEF = 3x = 3(22) = 66

angle FHG = 2x = y = 44

second image

2x - 21 + 42 = 3x - 21

42 = x

angle BCE = 3x - 21 = 3(42) - 21 = 105

angle CDE = 3y = 2x - 21 = 2(42) - 21 = 63
