The ratio of boys to the total number of children on the playground if, There are 24 boys and 16 girls on a playground is 3 / 5.
What is ratio?
It is the comparison of one quantity with another. For example, if your weight is 30 kg and your father's weight is 90 kg, then the ratio of weight is 1:3. An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
Given:
There are 24 boys and 16 girls on the playground,
Calculate the total number of children as shown below,
The total number of children = 24 + 16 = 40
The ratio of boys to the total number of children is given as,
The ratio of boys to the total number of children = number of boys / total number of children,
The ratio of boys to the total number of children = 24 / 40
The ratio of boys to the total number of children = 3 / 5.

Ronald drives his car down a road for 4 miles then turns around and drives back towards his starting point for 1 mile. what
is his distance traveled?
Answer:
5 miles
Step-by-step explanation:
4+1 =5
Answer:
5 miles
Step-by-step explanation:
Ronald's total distance traveled would be 5 miles because he travels 4 miles in one direction and 1 mile in another. 4+1= 5
His displacement would be 3 miles because he went, let's say, right 4 miles and then turned around and went left for 1 mile. This puts Ronald at 3 miles from his starting point.

An astronomer estimated the distance from Earth to Mercury to be 5.7 × 107 miles, and the distance from Earth to Neptune to be 2.7 × 109 miles. He wanted to know how many times farther it is from Earth to Neptune than from Earth to Mercury. Consider his work. 1. (2.7 × 109) (5.9 × 107) 2. ( 3.0 6.0 ) ( 109 107 ) 3. 0.5 × 102 The astronomer concluded that the distance in miles from Earth to Neptune is 50 times the distance from Earth to Mercury. Is he correct? If not, what was his mistake? Yes, he is correct. No, the numerator and denominator need to be switched in the expression. No, he needed to round down in his estimation of the coefficients. No, he needed to multiply the coefficients.
Answer:
Yes, he is correct.
Step-by-step explanation:

The astronomer is wrong, the numerator and denominator need to be switched in the expression.
How to solve exponential expressionDistance from Earth to Mercury = 5.7 × 10^7 milesDistance from Earth to Neptune = 2.7 × 10^9 milesDifference in distance = Distance from Earth to Neptune ÷ Distance from Earth to Mercury
= 2.7 × 10^9 ÷ 5.7 × 10^7
= 2.7 × 10^9 × 1 / 5.7 × 10^7
= 2.7 × 10^9 / 5.7 × 10^7
= (2.7 - 5.7) × 10^9-7
= -3 × 10² miles
Therefore, the astronomer is wrong,the numerator and denominator need to be switched in the expression.

One day 28 small and 12 large merchant spaces were rented. Another day, 30 small and 15 large spaces were rented. Write and evaluate an expression to show the total rent collected
Answer:
The expression which shows the total rent collected is S + L
The total rent collected is 85 of different size
Step-by-step explanation:
Let us list the given information
→ On one day: 28 small and 12 large merchant spaces were rented
→ Another day: 30 small and 15 large spaces were rented
Let S represents the small spaces and L represents the large spaces
∴ The total rent collected = S + L
∵ S in the two days = 28 + 30
∴ S = 58
∵ L in the two days = 12 + 15
∴ L = 27
Substitute The values of S and L in the expression of the total above
∴ The total rent collected = 58 small spaces + 27 large spaces
∴ The total rent collected = 85 of different size
The expression which shows the total rent collected is S + L
The total rent collected is 85 of different size

Random samples of size 81 are taken from an infinite population whose mean and standard deviation are 200 and 18, respectively. The distribution of the population is unknown. The mean and the standard error of the sampling distribution of sample mean are
Select one:
a. 200 and 18
b. 9 and 2
c. 81 and 18
d. 200 and 2 Correct
Answer:
D 200 and 2
Step-by-step explanation:
standard error of the sampling distribution of sample mean is expressed using the formula;
Standard error of the mean = S/√n where;
S is the standard deviation
n is the sample size
Given
S = 18
n = 81
SEM = 18/√81
SEM = 18/9
SEM = 2
The mean of the distribution according to the question is 200.
Hence the mean and the standard error of the sampling distribution of sample mean are 200 and 2 respectively.
