Answer: 290 children

Step-by-step explanation:

Jessica paid more than Amber at lunch.

To find out, we first need to calculate the amount of tip each person left:

Amber's tip = 11.70 x 0.18 = $2.11

Jessica's tip = 12.30 x 0.15 = $1.85

Then we add the cost of the lunch and the tip for each person:

Amber's total cost = 11.70 + 2.11 = $13.81

Jessica's total cost = 12.30 + 1.85 = $14.15

So Jessica paid $0.34 more than Amber for lunch.

Answer:

16 runners finished the race under 13 minutes.

Step-by-step explanation:

If you look at the green bars that are 11:00-12:59, 9:00-10:59 and 7:00 to 8:59 you will notice they are all under 13, The number of runners that finished it in 11:00-12:59 are 8, The number of runners that finished it in 9:00-10:59 are 6 and The number of runners that finished it in 7:00-8:59 are 2. 8+6+2 = 16

The number of runners who finished in under 13 minutes is 16.

A histogram is a representation of the distribution of data with intervals.

We have,

From the histogram,

Number of runners from 7:00 to 8:59 minutes = 2

Number of runners from 9:00 to 10:59 minutes = 6

Number of runners from 11:00 to 12:59 minutes = 8

The number of runners in under 13 minutes.

= 2 + 6 + 8

= 16

Thus,

The number of runners in under 13 minutes is 16.

12 x 5 = $60

Answer:

$60

Step-by-step explanation:

Let the monthly allowance be x

Let's Solve

\(x \times 20\% = 12 \\ x \times \frac{20}{100} = 12 \\ 20x = 12 \times 100 \\20x = 1200 \\ \frac{20x}{20} = \frac{1200}{20} \\ x = 60\)

Answer:

x=-4

Step-by-step explanation:

1.4x +2.6x = -16

combine like terms (numbers with numbers, and numbers with variables together)

4x = -16

get x by itself (isolation)

x = -4

Answer:

\(x=-4\)

Step-by-step explanation:

Start with:

\(1.4x+2.6x=-16\)

Combine like terms:

\(4x=-16\)

Divide both sides of the equation by the coefficient of \(x\), which is \(4\):

\(x=-4\)

Answer:

Angle 3 is 95 degrees because it is in a corresponding position to the 95 degrees, and lines A and B are parallel. Angle 4 is 85 degrees because it has to be supplementary to angle 3.

95+85=180

Answer:

Angle 4 is 85°

Step-by-step explanation:

Because the  lines are parallel the angles are congruent, you can find the supplementery angles when one angle is given by subtracting 180° by the angle given unless they are alternate interior angles. If they are alternate interior angles to the angle given then the angle willbe congruent to the original.

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer:

\(n = \frac{12}{5}\) or 2.4

Step-by-step explanation:

36 = 15n

Simply divide both sides by 15 to isolate n:

\(\frac{36}{15} = \frac{15n}{15}\)

\(\frac{36}{15} = n\)

\(n = \frac{12}{5}\) or 2.4

Step-by-step explanation:

Stephen has approximately $532.72 in his account at the end of 9 months with a 7.5% compound interest rate.

We can use the formula for compound interest to find the amount of money in Stephen's account at the end of 9 months:

A =P \((1 + r/n)^_(nt)\)

where:

A is the amount of money in the account at the end of the period

P is the principal (initial amount) in the account

r is the annual interest rate (as a decimal)

n is the number of times the interest is compounded per year

t is the time (in years)

We know that P = $500, r = 0.075 (since the interest rate is 7.5%), n = 12 (since the interest is compounded monthly), and t = 9/12 (since 9 months is three-quarters of a year). Substituting these values into the formula, we get:

A = \($500(1 + 0.075/12)^_{(12*(9/12))\) = \($532.72\)

Therefore, Stephen has approximately $532.72 in his account at the end of 9 months.

Answer:2:5

Step-by-step explanation: We can count the equal parts in the diagram to find the ratio of puzzles started to total puzzles, but that ratio is not one of the choices.

To make an equivalent ratio, we multiply both values in the first ratio by the same number. We can also divide both values by the same number.

Identifying the given ratio

6 + 9 = 15

There are 6 puzzles started for every 15 total puzzles.

The answer choices use smaller numbers. Let's create an equivalent ratio by dividing 6 and 15 by the same number.

Creating an equivalent ratio

We can divide 6 and 15 by 3 to get 2 and 5

Yes, the ratio 2:5 is equivalent to 6:15!

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.
