You want to know the opinions of drivers with valid licenses across America on the issue of establishing a law that requires individuals to take and pass another driver's test at the age of 65 to determine whether they may retain their license. You obtain a list of all licensed drivers and mail a survey to a random sample of 10,000 drivers. Of those, 6,457 responded and 46% say they favor the test. Which of the following statements is true? (5 points)
A. Because random sampling is used, we can feel confident that the percentage of all
drivers with a valid license who say they favor the test is close to 46%.
B. The results of this survey may be affected by nonresponse bias.
C. We cannot trust these results because the survey was mailed. Only survey results
from face-to-face interviews are considered valid.
D. Because more than half of those who were mailed the survey actually responded,
we can feel fairly confident that the actual percentage of all drivers with a valid
license who say they favor another test is close to 46%.
Answer:
The results of this survey may be affected by nonresponse bias
Step-by-step explanation:
Took the test :)
Answer:
B. The results of this survey may be affected by nonresponse bias.
Step-by-step explanation:
I took the test
Liz is making cookies for the annual bake sale at her
school. Each batch of cookies takes 2 3/4 cups of flour. If Liz
needs to makes 6 batches, how many cups of flour will
she need for all six batches?
Answer:
9
Step-by-step explanation:
It is very simple, 3/4 * 2 = 1.5
If we take 1.5 and multiply it by the amount of batches being made (6), we will have our answer.
1.5*6 = 9, so there we have our answer.
Hope this helps!
The amount of time is takes dora to commute to work is always within 5 minutes of the average number of minutes the commute takes. If the average ammount of time she takes to get to work is 45 minutes
Answer:
The average time to commute to work is 25 minutes.
Step-by-step explanation:
If average time for Dora to commute to work is 5 mins. If she takes 45 mins to get to work then her overall average time to commute to work will change as the average consists of 2 or more figures. The average time to commute to work is 25 mins ((5+45)/2). The average of 5 mins and 45 mins is 25 mins. This is the overall average time she takes to commute to her work.
3y−3x=21 Put the following equation of a line into slope-intercept form, simplifying all fractions.
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c )
Given
3y - 3x = 21 ( add 3x to both sides )
3y = 3x + 21 ( divide all terms by 3 )
y = x + 7 ← in slope- intercept form
what is l the value of x in the equation 4-[6+2(x - 4)] = 4x - 2(x+3)
Find the value of x so that the function has the given value.
j(x) = -4/5 +7; j(x) = -5
X =
Answer:
-78
Step-by-step explanation:
-4/5+7;j(x0= -5
-4/5 equals 0.8
0.8 equals 80
-80+7= -73
-73 - -5= -78
X= -78

There are two numbers that are twice as far away from 13 than 22. The sum of those numbers are?
Answer:
Sum of those numbers are 50
Step-by-step explanation:
Let x represent a number that is twice as far away from 13 than 22.
The number can't be less than 13 but will be between 13 and 22 or slightly more than 22 otherwise it will be far away from both.
Thus;
|x - 13| = 2|x - 22|
It's in absolute form, so we will square both sides to get rid of the absolute brackets.
Thus;
(x - 13)² = 4(x - 22)²
x² - 26x + 169 = 4(x² - 44x + 484)
x² - 26x + 169 = 4x² - 176x + 1936
4x² - x² - 176x + 26x + 1936 - 169 = 0
3x² - 150 + 1767 = 0
Using quadratic formula, we have;
x = 19 or x = 31
Thus,the sum of the 2 numbers = 31 + 19 = 50

Find the measure of the indicated angle to the nearest degree.
A. 36
B. 30
C. 54
D. 60
Answer:
54 degrees
Step-by-step explanation:
This is trigonometry. So we are given the adjacent leg and hypotenuse. So we can use cosine(cah from soh cah toa)
We will have to use the inverse of the trig ratios.
Remember!
cos^-1 is not 1/cos(that is sec)
cos^-1(27/46)
acos(27/46)
54.0586701 and so on
Round to nearest degree 54

Hernando ate 2/8 of a pizza for a dinner. he gave his 6 friends the rest of the pizza, and told them to share equally. To determine the fraction of the whole pizza that each of his friends received, Hernando performed the calculations below.
6/8 divided by 6= (6 divided by 6)/8= 1/8
he concluded that each person received 1/8 of the whole pizza. Are Hernando's calculations correct?
O yes they are correct. Hernando divided 6 by 6
O yes they are correct. Hernando divided 2/8 by 6
O No they are not correct. Hernando should have multiplied by 6, not divided by 6
O No, they are not correct. Hernando should have divided 8 by 6, not 6 by 6.
Answer: yes correct . hernando 6 by 6
Step-by-step explanation:
Answer:
yes they are correct. Hernando divided 6 by 6
Step-by-step explanation:
Hernando ate 2/8 of a pizza for a dinner.
he gave his 6 friends the rest of the pizza, and told them to share equally.
Rest pizza portion=1-2/8
=6/8
6/8 pizza divided into 6 person
6/8÷6
1/8
So 1/8 portion get each person
So the option a is correct
yes they are correct. Hernando divided 6 by 6

Can somebody help me please
Answer:
as it is isosceles triangle
40+40+x=180
x = 100°
Please helpp i need this rn if possible
Answer:
140, 60
Step-by-step explanation:
15x+5 + < CDB =180 line form an 180 angle
180-80-6x-6 = < CDB sum of angles in a triangle is 180
substitute < CDB from second to first
15x+5+180 -80-6x-6 =180
combine like terms
9x -81 =0
x=81/9=9
so angle YDC = 15*9+5 = 140 degrees
and angle DBC = 6*9+6= 60 degrees

uhm can yall give me an answer with explanationn plss
Answer:
123 degrees
Step-by-step explanation:
Angles in a quadrilateral add up to 360 degrees
so we add all the angles
114 + 80 + 43 which is 237
360 - 237 is 123
so angle x is 123 degrees
