To ease congestion in a downtown area, city planners are considering a plan to widen a major thoroughfare from
two driving lanes to three driving lanes. This plan would require closing a section of downtown streets as the work
begins. In order to assess public support for the plan, city planners provided a phone number to residents that could
be used to register opinion for or against the plan. In total, 267 calls were received, with only 24% supporting it.
Which statement describes the most likely type of bias in this setting?
This is nonresponse bias because many residents may choose to not participate.
This is question wording bias because the phrasing of the plan may have confused some residents.
This is voluntary response bias because residents could choose to call and register their opinion.
O This is response bias because residents may not be honest with their feelings about the plan.
Answer:
the answer is C. This is voluntary response bias because residents could choose to call and register their opinion.

Sam applies a force at 30° to the horizontal to move a football tackling dummy 10 m horizontally.
He does 160 J of mechanical work. Determine the magnitude of the force by using vector dot product.
Answer:
[tex]F=\frac{32\sqrt{3}}{3}\text{\:or\:} \approx 18.48\:\text{N}[/tex]
Step-by-step explanation:
We can find the horizontal component of force he applied by using the formula for work:
[tex]W=F\Delta x[/tex]
Solving for force, we have:
[tex]160=F\cdot 10,\\F=16\:\text{N}[/tex]
However he applied the original force at an angle of [tex]30^{\circ}[/tex] to the horizontal. This force of 16 newtons is only the horizontal component of that force. To find the magnitude of the original force, we can use basic trigonometry:
[tex]\cos 30^{\circ}=\frac{16}{x},\\x=\frac{16}{\cos 30^{\circ}},\\\\x=\frac{16}{\frac{\sqrt{3}}{2}},\\\\x=16\cdot\frac{2}{\sqrt{3}}=\frac{32}{\sqrt{3}}=\boxed{\frac{32\sqrt{3}}{3}}[/tex]
A box contains four red balls and eight black balls. Two balls are randomly chosen from the box, and are not replaced. Let event B be choosing a black ball first and event R be choosing a red ball second. What are the following probabilities? P(B) = ✔ 8/12 P(R | B) = ✔ 4/11 P(B ∩ R) = The probability that the first ball chosen is black and the second ball chosen is red is about percent
Answer:
P(B) = 8/12
P(R | B) = 4/11
P(B ∩ R) = 8/33
The probability that the first ball chosen is black and the second ball chosen is red is about 24 percent.
Step-by-step explanation:
I just got it right on edge 2020. Good luck with school!!
The probability that the first ball chosen is black and the second ball chosen is red is about percent is 66.67%.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, a box contains four red balls and eight black balls.
Let event B be choosing a black ball first and event R be choosing a red ball second.
Here, total number of outcomes = 4+8 =12
P(B) = 8/12 and P(R)=4/12
We know that, P(R|B) =P(R∩B)/P(B)
Here, P(R∩B)= 8/12 × 4/12
= 2/3 × 1/3
= 2/9
So, P(R|B) =2/9 × 12/4
= 2/3 ×100
= 66.67%
Therefore, the probability that the first ball chosen is black and the second ball chosen is red is about percent is 66.67%.

find the surface area of the composite figure
Answer:
791.7 in.²
Step-by-step explanation:
Surface area of the composite figure = ½(surface area of sphere) + surface area of cylinder
= ½(4πr²) + (2πr(h + r)
Where,
r = ½(12) = 6 in.
h = 9 in.
SA = ½(4*π*6²) + (2*π*6(9 + 6)
SA = ½(452.39) + 565.49
SA = 791.685
SA = 791.7 in.² (nearest tenth)

Step-by-step explanation:
Question 15
All you have to do for this one is to add the angle measures of 22 and 36 degrees together to get the answer of 58 degrees.
Question 16
The interior angles of a triangle will always add up to 180 degrees.
Therefore, 180 - 53 - 21 is the answer, which totals 106 degrees.

The probability of randomly selecting a female customer from a group of 34 customers in a supermarket is 85%. Which of the following describes the likelihood of selecting a female customer? A. unlikely B. likely C. neither likely nor unlikely
Answer:
b.likley
Step-by-step explanation:
We can look at this like if we have less than a 50% probability it would be unlikley, vice versa if we have a more than a 50% probability than it will be likley. and if we had exactly 50% iit will be none, but in this case we have 85% which is more than 50% so its likley. hope this helped bae

Answer:
11.5 square units
Step-by-step explanation:
It’s a 4 by 6 rectangle, so the total is 24. Then subtract the three little triangles on the outside. (Much easier than doing the main triangle).
1/2x1x4=2
1/2x1x6=3
1/2x3x5=7.5
2+3+7.5=12.5
24-12.5=11.5

Required
The lower bound
The lengths are approximately 6.7cm to 2sf are:
[tex]Length = \{6.65 \to 6.74\}[/tex]

Two trains, Train A and Train B, weigh a total of 351 tons. Train A is heavier than Train B. The difference of their weights is 181 tons. What is the weight of each train?
Answer:
Train A is 266 and Train B is 85
Step-by-step explanation:
If the difference is 181 tons, then subtract the difference to get double the weight of the lightest train.
351 - 181 = 170
170 ÷ 2 = 85
If B is the lightest, B is 85.
For A, either add the difference back or subtract 85 from 351.
85 + 181 = 351 - 85 = 266

What is x if 2784 = 36x?
Answer:
77 1/3
Step-by-step explanation:
to get x you have to divide both sides by 36
2784=36x
x=77 1/3
you can also use an algebra calculator for it
Answer:
77.333
Step-by-step explanation:
So we are given the equation
2784 = 36x
But we need to find the value of just x. So if 36 x = 2784:
2784/36 = x
How did we do this? Well, we divided each side of the equation by 36, which gives us the amazing value of just x.
Solve the equation
77.333 = x
Now, lets check our work:
77.333 x 36 = 2783.88
This is the closest I believe we can get.
Hope this helps!

A plumber can complete a job in 2 hours. If an apprentice helps, it takes only 1 1/3 hours. How long would it take the apprentice working alone?
Hello there I hope you are having a great day :) You Question A plumber can complete a job in 2 hours. If an apprentice helps, it takes only 1 1/3 hours. How long would it take the apprentice working alone?
(1 1/3) / 2 + (1 1/2) / a = 1
(4/3)a + (4/3)2 = 2a multiply both sides by 2a
(4/3)2 = (2/3)a subtract (4/3)a from both sides
8/3 = 2a/3 simplify
8 = 2a
4 = a
