Problem Andrey works at a call center, selling insurance over the phone. While debating which greeting he should use when calling potential customers — "Howdy!" or "Hiya!" — he decided to conduct a small study. For his subsequent 500500500 calls, he chose one of the greetings randomly by flipping a coin, and used the same script for his sale otherwise. Then, he compared the percentage of calls he succeeded in selling insurance using each greeting. He noticed that he was significantly more likely to make a sale in calls that started with "Hiya!" Can we conclude that the greeting caused the difference in sales? Why? Choose 1 answer:
Answer:
Yes, because the calls were each randomly assigned a greeting.
Step-by-step explanation:
It is given that Andrew who works at the call center of an insurance company, decided to conduct a small survey on how to greet the potential customers while calling.
For this, he uses his 500 subsequent calls and he chooses to greet his customers randomly as "Howdy" or "Hiya".
Since the selection bias is ruled out, the calls were randomly assigned for the greetings. Thus the greetings caused a difference in sales.
Answer:
Yes, because the calls were each randomly assigned a greeting
Step-by-step explanation:
Random assignment to treatment groups makes this study an experiment, so we can make causal conclusions.
The rectangle below has an area of 70y^8 + 30y^6. The width of the rectangle is equal to the greatest common monomial factor of 70y^8 and 30y^6. What is the length and width of the rectangle?
Answer:
Length: 7y^2+3
Width: 10y^6
Step-by-step explanation:
Given that the rectangle has an area of 70y^8 + 30y^6.
The width of the rectangle is equal to the greatest common monomial factor of 70y^8 and 30y^6.
First let us get the width;
70y^8 = 7 * 10 * y^2 * y^6
30y^6 = 3 * 10 * y^6
Since 10y^6 is common to both factors, hence the width of the rectangle will be 10y^6
Given;
Area = Length * width
A(x) = W(x)*L(x)
A(x) = 70y^8 + 30y^6
A(x) = 10y^6(7y^2+3)
On comparison
L(x) = 7y^2+3
Hence length is 7y^2+3 and width is 10y^6
When Elijah left his house in the morning, his cell phone battery was partially
charged. The charge remaining in Elijah's battery, as a percentage, can be modeled by
the equation B = 27 – 4.5t, where t is the number of hours since Elijah left his
house. What is the slope of the equation and what is its interpretation in the context
nf the problem?
Answer:
The slope is -4.5
The slope means that Elijah's phone battery will decrease by 4.5 percent each hour.
Step-by-step explanation:
In the equation y = mx + b, m is the slope.
The coefficient in the equation B = 27 – 4.5t is -4.5. This means that -4.5 is the slope of the equation.
In the context of this problem, the slope will represent the percent that Elijah's phone battery will decrease per hour.
So, the slope means that Elijah's phone battery will decrease by 4.5 percent each hour.
Is there a pattern behind prime numbers?
Answer:
There is a rule on how we find prime numbers.
Step-by-step explanation:
A clear rule determines exactly what makes a prime: it's a whole number that can't be exactly divided by anything except 1 and itself. But there's no discernible pattern in the occurrence of the primes.That's because, after the number 5, there are only four possibilities — 1, 3, 7, and 9 — for prime last digits

10. Giselle invests $16,250 in an account that earns 4.25% interest, compounded continuously.
How long, rounded to the nearest year, will it take for Giselle's money to grow to $40,000?
Answer: 24 years
Step-by-step explanation:
% • total = Answer
4.25% • $40,000 = Answer
.0425 • $40,000 = Answer
Answer = $1,700 per year
40,000 ÷ 1,700 = 23.5
23.5 rounded to the nearest year is 24

Lateral area =
Total area =
Volume =
Answer:
Lateral area = 2.pi.r.h = 2 x pi x 2 x 3 = 12 pi
Total area = lateral area + pi. r^2 . 2 = 20 pi
Volume = pi . r^2 . 2 . h = 24 pi
Fine the area of the regular figure
Answer:
139.5 mm
Step-by-step explanation:
The area of a geometric shape with all sides of equal length is:
A (1/2)nsr
n = the number of sides
s = the length of the sides
r = the length of the apothem
The apothem is the line going from the center point of the shape to the middle of one of the sides.
A = (1/2)(5)(9)(6.2)
A = (1/2)279
A = 139.5 mm

25) Margie needs to borrow $9,000 from a local bank. The
loan has a 8.5% interest rate for 4 years. What will
Margie's monthly payment be?
A) $ 221,850.00
B) $3060.00
C) $250.0
D) $ 221.85
Answer:
B) $3060.00
Step-by-step explanation:
8.5% of 9,000 equals 765, then 765 multiplied by 4 equals 3060.
I think that it will take Margie 4 years to pay back the bank. And the interest rate that the bank charges is 8.5% per month.
I'm not sure if this is correct

A rectangle has an area of 99 square in. What is the length of the long side?
Answer:
The longer length is either 99, 33 or 11 inches
Step-by-step explanation:
Given
[tex]Area = 99[/tex]
Required
The length of the longer side
Area of a rectangle is:
[tex]Area = Length * Width[/tex]
List out all possible products that give 99 [Assume the dimension are whole numbers]
[tex]Length * Width = 99 * 1 = 99[/tex]
[tex]Length * Width = 33 * 3 = 99[/tex]
[tex]Length * Width = 11 * 9 = 99[/tex]
List out the longer factors
[tex]L = \{99, 33, 11\}[/tex]
Hence, the longer length is either 99, 33 or 11 inches
Find the area of the shaded figure in the diagram below. Use 3.14 for π and round your answer to the nearest hundredth.
A. 39.57in^2
B. 66.89 in^2
C. 200.67 in^2
D. 118.72 in^2
Answer:
D
Step-by-step explanation:
diameter of 1 circle = 21.3/3= 7.1
radius of 1 circle= 7.1/3=3.55
area of 1 circle =πr^2=3.14× (3.55)^2=39.57
area of 3 circle= 39.57×3=118.72
therefore,area of shaded portion= area of 3 circle =118.72

The local skating rink pays Mary a fixed rate per pupil plus a base amount to work as a skating instructor. She earns $90 for instructing 15 students on Monday afternoon. Last Friday, she earned $62 for working with 8 students. Lisa is also a skating instructor. She receives half the base amount that Mary does, but she is paid twice as much per student. Who would earn more money instructing a class of 20 students?
Answer:
lisa would earn more money
Step-by-step explanation:
let say mary base price = x
mary per student price = y
x+15y = 90
x+8y = 62
7y = 28
y =4
x = 30
mary will earn for 20 students = 30 + 20*4 = 110
lisa base money = 30/2= 15
lisa per student = 4*2=8
lisa earning for 20 students
= 15 + 20*8 = 175
lisa will earn more money

what is the surface area of this rectangular prism?
Answer:
Step-by-step explanation:
2 surfaces that are 5x7
2 surfaces that are 4x7
and the top and bottom that are 4x5
2*5*7 = 70
2*4*7 = 56
2*4*5 = 40
total surface is 166 [tex]cm^{2}[/tex]
Answer:
166 square centimeters
Step-by-step explanation:
Surface area of a rectangular prism can be found by finding the area of each of the six surfaces of the prism. Remember that opposite sides on a rectangular prism are equal to each other, as they have the same side lengths. Because of this, the equation for surface area can be described as: 2lw + 2lh + 2wh. In this case, the length l is represented by 5cm, the width w is 4cm, and the height h is 7 cm. Now you can solve for the surface area:
SA = 2lw + 2lh + 2wh
SA = 2(5 x 4) + 2(5 x 7) + 2(4 x 7)
SA = 2(20) + 2(35) + 2(28)
SA = 40 + 70 + 56
SA = 166
Recall that units of area are given as square units, and the measure of this rectangular prism is given in centimeters. The answer is then given in square centimeters.
SA = 166 square centimeters
The perimeter of a square is 36 feet. If you increase the length by 3 feet and decrease the width
by 2 feet, what is the area of the new figure?
Answer:
84 feet
Step-by-step explanation:
If the perimeter is 36 feet, and all the sides are the same length, then all the sides are 9. if we increase the length by 3 feet and decrease the width by 2 feet then we are left with 12 * 7 = 84
Michael just accepted a job salary of $53000. Michael was told that for each year stays with the company, he will be given a salary raise of $4500. How much would Michael make as a salary after 10 years working for the company? What would be his salary after t years?
Answer:
98,000
and for the t it would be an equation-
4500y=t
y= years worked for a company
Step-by-step explanation:
it is 98000 because 4500*10 because 4500 more each year.
and the 4500y=t is 4500 times the of years he has worked there equals t, or his salary after the 4500 is added.

Answer:
d = 126, z = 28
Step-by-step explanation:
The angle with the variable is diagonal from the 105 degree angle. In this case, that means that they are equivalent. So, 105+21 = 126. d = 126 :)
