Answer:
- A → B: 1/3
- correct
- A → B: 2/5
Step-by-step explanation:
It is clear from your answer to the second part that you know the A→B scale factor is the reciprocal of the B→A scale factor. Use that fact for the other two parts of the question.
- A → B = 1/3; B → A = 3
- A → B = 2; B → A = 1/2
- A → B = 2/5; B → A = 5/2

It is convenient to find a unit length (or the smallest length) on the smaller figure, then see how much that is multiplied by to get the larger figure.
- B : A = 1 : 3
- A : B = 1 : 2
- B : A = 2 : 5
Once you have these ratios, you need to determine what the notation A→B is supposed to mean. Here, we presume it means B/A.
The value of d in equation Q/R=8/d is 8R/Q.
Given an equation Q/R=8/d.
We are required to find the value of d in the given equation.
Equation is basically the relationship between two or more variables that are expressed in equal to form. The values that we enter is known as domain and the values that we get is known as range. It can be linear equation, quadratic equation, cubic equation.
The equation is :Q/R=8/d
We have to take d in right side of equal to sign and Q,R to the left side of right side of equal to sign.
d=8R/Q
Hence the value of d in equation Q/R=8/d is 8R/Q.

In quadrilaterals inscribed in circles, the sum of opposite angles=180 degrees. so, x+134=180
Answer:
0.288 < p < 0.338
Step-by-step explanation:
We have 2331 adults polled and 730 said they believe in UFOs. We are to construct a 99% confidence interval for the population proportion. We are told to round to 3 decimal places as needed.
We need to find p-hat and q-hat
p-hat = 730/2331 = 0.313
q-hat = 1 - p-hat = 1 - 0.313 = 0.687
Since the sample size is greater than 30, we use a z-value for 99% confidence, which is 2.575
See attached photo for the construction of the confidence interval
I think it’s B but I don’t really know so…
