Answer:
27:33
Step-by-step explanation:
If u multiply both sides of the ratio by the same number, u get an equivalent ratio. By multiplying 9:11 by 3 on both sides, you get 27:33. The difference refers to subtraction. 33-27= 6 which is the difference between the two numbers.
Answer:
There were 423 adult tickets sold.
Step-by-step explanation:
Let x = the number of adult tickets sold
Let x + 65 = the number of student tickets sold
x + x + 65 = 715
2x = 715
x = 357.5
x + 65 = 422.5 (round up)
Answer:
Option a) 50% of output expected to be less than or equal to the mean.
Step-by-step explanation:
We are given the following in the question:
The output of a process is stable and normally distributed.
Mean = 23.5
We have to find the percentage of output expected to be less than or equal to the mean.
Mean of a normal distribution.
- The mean of normal distribution divides the data into exactly two equal parts.
- 50% of data lies to the right of the mean.
- 50% of data lies to the right of the mean
Thus, by property of normal distribution 50% of output expected to be less than or equal to the mean.
Answer:
So slope 1 would be positive
Slope 2 would be negative
Slope 3 would be zero
Step-by-step explanation:
If the slope is moving up from left to right, then it is positive
If the slope is moving down from left to right, then it is negative
If the slope is a vertical line and is not moving left/right, then it is undefined
If the slope is a horizontal line and is not moving up/down, then it is zero
So slope 1 would be positive because it is moving up from left to right.
Slope 2 would be negative because it is moving down from left to right.
Slope 3 would be zero because it is a horizontal line that is not moving up or down.
Hope this helped!
