The histogram shows the number of minutes that users waited to register for classes on a university's online system. According to the histogram, how many users waited more than a hour but not more than 2 hours?
A) 2
B) 8
C) 9
D) 11
Answers
Answer: the answer is 4
Step-by-step explanation:
11 users waited more than a hour but not more than 2 hours.
What is Histogram?A histogram is a graphical depiction of continuous or discrete data. In a histogram, the frequency is represented by the area of a bar. Frequency density, which is proportional to frequency, is plotted on the y-axis, and intervals representing the range of values are plotted on the x-axis.
From the Histogram we have
For 0 -30 minutes - 5 users wait
31- 60 minutes- 4 users wait
61- 90 minutes- 9 users wait
91- 120 minutes- 2 users wait
120- 150 - 4 users wait
So, the number of users waited more than a hour but not more than 2 hours
= 9 + 2
= 11 users

A business school is conducting a study to investigate whether a students’ scores on a placement test can be used to predict students’ starting salaries. Based on a random sample of 200 graduates of the business school, a 98 percent confidence interval for the slope of the linear regression line relating placement scores and starting salary is calculated to be (315,336). Assume the conditions for inference are met.
Which of the following is a correct interpretation of the confidence interval?
a. There is a 98 percent probability that the slope of the population regression line is between $315 per point and $336 per point.
b. Ninety-eight percent of the time, a 10-point increase in placement score will result in an average increase between $3,150 and $3,360 in starting salary.
c. We are 98 percent confident that a 10-point increase in placement score will result in a predicted increase in starting salary of between $3,150 and $3,360.
d. We are 98 percent confident that predicted starting salaries will be between $315,000 and $336,000.
e. We are 98 percent confident that the regression equation can be used to make accurate predictions for placement scores between 315 and 336.

Answers
Step-by-step explanation:
180-123 = 57 G = 57
6x -1 + 5x +14 +57 = 180
11x = 110
x = 10
H = 6(10) - 1 = 59
Answer:
59°
Step-by-step explanation:
Use the equation:
( 6x - 1 )° + ( 5x + 14 )° = 123°
Combine like terms
6x + 5x = 11x -1 + 14 = 13
New simplified equation:
11x + 13 = 123
Subtract 13 from both sides of the equation
11x + 13 = 123
-13 -13
We are subtracting because the opposite of addition is subtraction and we are using PEMDAS backwards to isolate the variable 'x' on one side of the equation.
Equation now:
11x = 110
Divide both sides of the equation by 11
[tex]\frac{11x}{11}[/tex] = [tex]\frac{110}{11}[/tex]
Solve
x = 10
Solve for the measure of angle H

Evaluate: x + (x2 - xy) - y
if x = 5 and y = 4
Answers
When x = 5 and y = 4, the expression [tex]x + (x^2 - xy) - y[/tex] evaluates to 6.
To evaluate the expression [tex]x + (x^2 - xy) - y[/tex] when x = 5 and y = 4, we substitute the given values into the expression and perform the
calculations:
[tex]x + (x^2 - xy) - y\\x= 5 + (5^2 - 5*4) - 4\\x= 5 + (25 - 20) - 4\\x= 5 + 5 - 4\\x= 10 - 4\\x= 6\\[/tex]
It's crucial to remember that the expression in question is not an equation that represents a graph, nevertheless. It is merely an algebraic expression that, given the values of "x" and "y," evaluates to a single value. We need an equation that connects 'x' and 'y' and specifies the relationship between them if we are to construct a graph.
Therefore, when x = 5 and y = 4, the expression [tex]x + (x^2 - xy) - y[/tex] evaluates to 6.

k^2 - 5k = k + 7k^2 - 6k = 7k^2 - 6k + 9 = 16k - 3 = 4 ⇒ k = 7k - 3 = -4 ⇒ k = -1#3
