Answer: d. 25
Step-by-step explanation:
Let x be the total number of students in the class.
As per given :
Number of students want ice cream party = 20% of x= 0.20x
[we divide percent by 100 to convert it into decimal.]
Actual number of students want ice cream party =5
⇒ 0.20x=5
Divide both sides by 0.20 , we get
⇒ x= 
Hence, the total number of students in the class.= 25
Thus , the correct answer is d. 25
210/ 35 = 6
she burns 6 calories per minute.
Answer:
The correct option is C) Both of the above.
Step-by-step explanation:
Consider the provided statement.
First understand the meaning of Confidence level.
Confidence level refers to the percentage of likelihood, or assurance, that when you draw a random sample several times, the confidence interval will contain the true population variable.
99% confidence means We are 99% sure that most of these confidence intervals contain the true parameter of the population.
Therefore, both the statement are correct.
Hence, the correct option is C) Both of the above.
The car on a Ferris wheel with a radius of 20 feet. travels a distance of 125.6 feet.
In order to determine the distance that the car has travelled, we will use the formula for calculating the circumference of a circle.
<h3>How to calculate Circumference of a circle</h3>
C = 2πr
where
r = radius
Therefore,
r is the radius of the fairy wheel
r = 20 ft
C = 2 × 3.14 × 20
C = 40 × 3.14
C = 125.6 ft
This shows that the car on a Ferris wheel with a radius of 20 feet. travels a distance of 125.6 feet

Total juice boxes = 3 + 1 + 2 + 4 = 10
probability first one out is grape = 2 / 10
probablility second one out is grape 1 / 9 (one taken already and only nine left)
total probability = 2 / 10 x 1 / 9 = 2 / 90 = 1 / 45
