total is one hour plus five mins
so 1 hr 5 mins
Answer:
1 hour and 5 minutes
Step-by-step explanation:
Between 4:22 pm and 3:17 pm, 1 hour has passed.
3:17 + 1 hour = 4:17
Between 4:17 pm and 4:22 pm, 5 minutes has passed.
4:17 + 5 minutes = 4:22

Over the last 3 evenings, Huda received a total of 94 phone calls at the call center. The third evening, she received 3 times as many calls as the second evening.
The second evening, she received 9 fewer calls than the first evening. How many phone calls did she receive each evening?
Please answer??
Answer: See explanation
Step-by-step explanation:
Let the number of calls received the first evening be x.
The second evening, she received 9 fewer calls than the first evening. This will be: = x - 9
The third evening, she received 3 times as many calls as the second evening. This will be: = 3(x - 9) = 3x - 27
Then, the expression for each evening can then b put together and solved further as:
x + (x - 9) + (3x - 27) = 94
x + x - 9 + 3x - 27 = 94
5x = 94 + 9 + 27.
5x = 130
x = 130/5
x = 26
First evening = 26 calls
Second evening = x - 9 = 26 - 9 = 17 calls
Third evening = 3x - 27 = 3(26) - 27 = 78 - 27 = 51 calls
Suppose that a survey was taken of 320 people and each person was asked if they approved or disapproved of the president's actions during the government shutdown.

Which of the following statements correctly describes how the confidence interval for the population proportion of people that approved the President's actions during the government shutdown?
A) There are not 15 successes and 15 failures. A confidence interval can be computed by adding 2 successes and 2 failures.
B) There are not 15 successes and 15 failures. A confidence interval can be computed by adding 4 successes and 5 failures.
C) There are not 15 successes and 15 failures. A confidence interval can not be done.

A company found that monthly reimbursements to their employees could be adequately modeled by a uniform distribution over the interval $10,000 < x < 15,000.
What is the probability of employee reimbursements exceeding $12,000 next month?
Answer:
0.6 = 60% probability of employee reimbursements exceeding $12,000 next month
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
A company found that monthly reimbursements to their employees could be adequately modeled by a uniform distribution over the interval $10,000 < x < 15,000.
This means that, in thousands of dollars, [tex]a = 10, b = 15[/tex]
What is the probability of employee reimbursements exceeding $12,000 next month?
[tex]P(X > 12) = \frac{15 - 12}{15 - 10} = \frac{3}{5} = 0.6[/tex]
0.6 = 60% probability of employee reimbursements exceeding $12,000 next month

Answer:
A, B, D
Step-by-step explanation:
The "form factor" in the attached is the difference between the sum of the squares of the short sides and the square of the long side. If that difference is 0, the Pythagorean theorem is satisfied, and the triangle is a right triangle. When the difference is positive, the triangle is acute; negative, the triangle is obtuse.
As you can see, all but the third triangle are right triangles.

Proofs in the picture
The value of y is 225 when x is 50 from the given graph.
What is Coordinate System?Arrangement of reference lines or curves used to identify the location of points in space is called as Coordinate system.
We need to find the value of y when x is fifty.
In the given graph we have to draw a perpendicular line at x =50.
Now we have to check the point where the perpendicular line touches the graph curve.
Take the corresponding value of y.
When x is 50 the value of y is nearly to 225.
Hence, the value of y is 225 when x is 50.

the perimeter of a rectangle is 24 inches. The length is 2 inches. what is the width?
Answer:
width = 10
Step-by-step explanation:
Step-by-step explanation:
P=24
L=2
Perimeter of rectangle is 2(L+W)
24=2(2+W)
24=4+2W
Subtract 4 from both sides you get 20=2W
Now divide by 2 on both sides you get W=10 inches

A)
Intersection
B)
Union
C)
All real numbers
D)
No solution
The absolute value of the inequality |2x -1| >3 will have a union type of solution set.
How do we solve the absolute value of an inequality equation?The absolute value of an inequality equation can be solved by applying the absolute rule that says:
If |u| > a, a > 0, then u < - a or u > awhere;
the "or" functionality symbolizes the union between the solution sets.Given that:
|2x - 1| > 3Applying the absolute rule, we have:
= 2x - 1 < - 3 or 2x - 1 > 3
= 2x < -4 or 2x > 4
= x < -4/2 or x > 4/2
= x< -1 or x > 2 which denotes the union of between the solution sets.

Sum of 2 numbers is 36. The larger is 3 more than twice the
smaller number, Find the smaller number below.
Answer:
11
Step-by-step explanation:
so we just make a system of equations:
x+y=36
say that x is the larger and y is the smaller
x-3=2y
so we can combine the equations and solve for x and y
re-arrange x-3=2y to be x=2y+3
x+y=36
x=2y+3
insert the value for x into x into x+y=36
2y+3+y=36
3y+3=36
y=11
now insert that back into x+y=36
11+x=36
x=25
Out of the two numbers x and y, 11 is the smaller number

How do i solve for x if (x+1)/(x+1)= 1/2?
Answer:
x= -1
Step-by-step explanation:
Given data
We have the expression as
(x+1)/(x+1)= 1/2
let us first cross multiply
2(x+1)=(x+1)
2x+2=x+1
collect like terms
2x-x=1-2
x= -1
Hence the value of x=-1
