Some sources of bias may be:
The fact the company is calling in such a narrow time window. They need to expand their hours of operation. Not everyone has a listed phone number, and many cell phones are unlisted, so that leaves many people out of the picture. The sample is likely not representative of the population. The company may be better off doing email or social media surveying methods. Many people often get annoyed at unsolicited phone calls, so they may not be willing to do a survey. Those that do answer the survey may show off volunteer response bias which is often present in political surveys.Answer:

Phone calls to New York are charged at the rate of £2.90 for a 5-minute call. John’s call costs £7.86. How long (in minutes) was his call?
Answer:
Step-by-step explanation:
5 min = 2.90
xmin = 7.86
with cross multiplication;
xmin = 7.86*5min/2.90
x = 13.55=14.0
therefore x = 14min
so he will make of 14min long

Which equation is correct? o 39 x 3 = 30 x 3 + 9x 3
o 39 x 3 = 30 +9x3
o 39 x 3 = 300 × 3+9×3
39×3=30×3+9
39x3=30x3+9x3
117=90+27
117=117
39x3=30+9x3
117=30+27
117=57
39x3=300x3+9x3
117=900+27
117=927
39x3=30x3+9
117=90+9
117=99
So the first one is correct.

D. 137 [tex]m^{2}[/tex]
Step-by-step explanation:
First, get the area of the rectangle:
[tex]A_{Rectangle} =length *width[/tex]
[tex]A_{Rectangle}=(15)(11)=165[/tex]
Then, get the area of the triangle:
[tex]A_{Triangle} =\frac{height*base}{2}[/tex]
[tex]A_{Triangle}=\frac{8*7}{2} =28[/tex]
Now substract the area of the triangle from the rectangle:
165 - 28 = 137
∴ 137 [tex]m^{2}[/tex]

Clue 3) I am not equal to -2 + (-1).
Clue 4) I am not equal to 2 - 6.
Who am I??
HELPPP ME PLEASEEEEEE
Answer:
- 5
Step-by-step explanation:
"I am a negative integer greater than -6."
This eliminates any number that is less than -6, as well as any positive number.
0 > x > -6
"I am less than -2."
This narrows down the possible numbers to:
-5, -4, -3.
"I am not equal to -2 + (-1)"
-2 + - 1
-2 - 1
- 3
The number is not '-3'.
"I am not equal to 2 - 6."
2 - 6
- 4
The number is not -4.
Your number should be -5.
Hope this helps.

At Ivanna's auto shop, it takes her 15 minutes to do an oil change and 24 minutes to do a tire change. Let x be the number of oil changes she does. Let y be the
number of tire changes she does.
Using the values and variables given, write an inequality describing how many oil changes and tire changes Ivanna can do in at most 2 hours (120minutes)
Plzzz help
Answer:
15x + 24y <= 120
Step-by-step explanation:
It takes 15 minutes per oil change, 15x
It takes 24 minutes per tire change, 24y
In at most 120 minutes, so it must be less than or equal to the time available.
What is 900 divided by 3, and why?
Answer:
300
Explanation:
look at the file below
300 is the quotient or the result of dividing 900 by 3.
The result of dividing 900 by 3 is 300.
To understand why, we perform the division operation:
= 900 ÷ 3
= 900 /3
= (3 x 3 x 2 x 2 x 5 x 5) / 3
= 3 x 2 x 2 x 5 x 5
= 3 x 4 x 25
= 12 x 25
= 300
When we divide 900 by 3, we are essentially splitting 900 into three equal parts. Each part is 300.
Therefore, 300 is the quotient or the result of dividing 900 by 3.

I gotta say what's on my mind
Something about us doesn't seem right these days
Life keeps getting in the way
Whenever we try, somehow the plan
