Beanie works cleaning carpets. He charges $99 per room. If he cleans 3 rooms in one home, 5 in another, and 4
in a third home, how much will he make?
A. $693
B. $1188
C. $891
D. $792
Answer:
B. $1188
Step-by-step explanation:
If he makes $99 per room, add all the rooms first:
3 + 5 + 4 = 12 rooms total
Then multiply the number of rooms by the price per room:
$99 * 12 = $1188
An elevator is traveling underground at a constant rate. The equation y= -2x - 10 can be used to represent this situation, where y is the position of the elevator underground in feet and x is the number of seconds the elevator has been traveling Which statement best describes the position of the elevator, given this equation?
O From a starting position of 2 feet underground, the elevator is descending 10 feet per second
O From a starting position of 10 feet underground, the elevator is descending 2 feet per second
O From a starting position of 2 feet underground, the elevator is ascending 10 feet per second
O From a starting position of 10 feet underground, the elevator is ascending 2 feet per second
4 is correct
reason is because the number next to x is the constant number and the end number is where you started

A peacock walks 6 feet in 15 seconds how many feet can a peacock walk in 98 seconds?
Answer:
[tex]Distance = 39.2[/tex]
Step-by-step explanation:
Given
[tex]Distance = 6ft;\\ Time = 15seconds[/tex]
Required
Determine the distance covered in 98 seconds
To solve this, the following assumption must be made:
The peacock walks at a constant speedSo, first we calculate the speed
[tex]Speed = \frac{Distance}{Time}[/tex]
Substitute 6 for Distance and 15 for Time
[tex]Speed = \frac{6}{15}[/tex]
[tex]Speed = 0.40[/tex]
Next, is to calculate the required distance
[tex]Speed = \frac{Distance}{Time}[/tex]
In this case:
[tex]Speed = 0.40[/tex] because it is constant and
[tex]Time = 98[/tex]
The expression becomes:
[tex]0.40 = \frac{Distance}{98}[/tex]
Make Distance the subject:
[tex]Distance = 0.40 * 98[/tex]
[tex]Distance = 39.2[/tex]
The peacock will walk 39.2 feet in 98 seconds

A basketball player makes 65% of all free throws in her first 5 seasons. In her 6th season she makes 105 out of 150 free throws. How does the observed frequency of her 6th season compare to the expected frequency? Provide a possible explanation for any similarities or differences in the frequencies. 7.50.3.7
(35 points i think)
If a basketball player makes 65% of all free throws in her first 5 seasons. The observed proportion is higher than the expected proportion, indicating that the player performed better than expected in her 6th season.
What is the observed frequency of her 6th season?The expected frequency of successful free throws in the 6th season can be calculated based on the player's overall success rate in the first 5 seasons. Since the player made 65% of all free throws in her first 5 seasons, we can expect her to make 65 out of 100 free throws in any given season. Therefore, the expected frequency of successful free throws in the 6th season would be:
Expected frequency = (65/100) * 150 = 97.5
The observed frequency of successful free throws in the 6th season is 105.
To compare the observed and expected frequencies, we can calculate the standardized residual (z-score) as follows:
z-score = (observed frequency - expected frequency) / sqrt(expected frequency * (1 - expected frequency / total sample size))
total sample size = 150
expected frequency = 97.5
observed frequency = 105
z-score = (105 - 97.5) / sqrt(97.5 * (1 - 97.5/150)) = 1.28
The z-score of 1.28 suggests that the observed frequency is 1.28 standard deviations above the expected frequency. This indicates that the player's success rate in the 6th season is higher than what would be expected based on her overall success rate in the first 5 seasons.
Possible explanations for the difference in frequencies could be due to factors such as improvements in the player's technique, changes in the player's physical or mental state, or random variation. It is also possible that the sample size of 150 free throws in the 6th season is not large enough to draw definitive conclusions about the player's success rate in that season.

There are two ways you can figure it out.
One way is to choose any two distinct points (x1,y1) and (x2,y2) on the line then use the slope formula below to find the slope m.
m=y2−y1x2−x1. So your points are (-2,2) and (-2,3)

Luis wants to buy Jordans for 75.23. He saves 10.27 per month. Write an equation to solve how many months he'll need to save.
Answer:
75.23=10.27x
Step-by-step explanation:
x will represent how many months Luis will save and it will equal 75.23. To find the value of x, divide 10.27 on both sides and get x=7.32. That means Luis will need to earn 10.27 for 7.32 months to get Jordans.

Richard is walking around her neighborhood. If he walks
1
3
mile in
1
6
hour, how fast is Richard walking, in miles per hour?
Answer:2 miles per hour
Step-by-step explanation:
1/3 times 6
To determine how fast is Richard walking, the concept of average speed comes into picture. The average speed of Richard is 2 miles per hour. Therefore the correct option is option B
What is Average speed?Average speed can be calculated by dividing total distance traveled by a body to the total time taken for the body to reach its destination.
Now determine how fast is Richard walking, in miles per hour
We have to calculate the average speed which is the ratio of the total distance traveled by a body to the total time
Total distance traveled by Richard = 1/3 mile
Total time taken = 1/6 hour
Average speed = total distance / total time
Average speed = (1/3) / (1/6)
Reciprocal the denominator term, and we get
Average speed = (1/3) × 6
Average speed = 2 miles per hour
Therefore, Richard is at an average speed of 2 miles per hour
