What is the probability that both spinners will land on the same number?
What is the probability that both spinners will land on - 1

Answers

Answer 1
Answer: First, I'm not sure if this at all correct but um, I counted up all the pieces in both circles and there are 9 pieces in total. Since both circles have 1, 2, and 3 as the same numbers, there are 1 of each in the circles, so the probability is 2 over 9. Hope that helped and good luck! :]

If you answered 37 problems correctly on a 42 question test, what percent would you recieve

Answers

The fraction would be 37 out of 42. You basically divide the two and get something around 88%.

Final answer:

On a test with 42 questions, answering 37 correctly yields a score of approximately 88 percent. This result is obtained by dividing the number of correctly answered questions by the total number of questions, and then multiplying that result by 100 to find the percent.

Explanation:

The subject for this problem is percentages, a common topic in mathematics. To solve this, you need to relate the number of correct answers to the total number of questions. The formula for percent is (part / total) * 100, where the part is the number of problems you answered correctly (37), and total is the overall number of questions on the test (42).

In this case, you'd calculate (37 / 42) * 100, which equals approximately 88.09%. Therefore, if you answered correctly on 37 out of 42 questions, your score would be about 88 percent.

What symbol do you use for square root on pc?

Answers

For this case we must find the values of "a" and "b" that make the expressions equivalent:

We have:

\sqrt {\frac {126xy ^ 5} {32x ^ 3}} =

We take common factor "2" from the numerator and denominator:

\sqrt {\frac {2 * (63xy ^ 5)} {2 * (16x ^ 3)}} =

Eliminating common factors of numerator and denominator:

\sqrt {\frac {63y ^ 5} {16x ^ 2}} =

So, we have that the values of a and b are:

a = 16\nb = 2

Answer:

a = 16\nb = 2

Write a piecewise function that models each telephone billing plan. Then graph the function.$60 per month buys 450 minutes. Additional time costs $0.35 per minute.

Answers

if  0 < x ≤ 450, y = $60.

if 450 < x ; y = $60 + (x - 450min) × $0.35

the calculation is as follows:

Here x will represent the number of minutes.

so if  0 < x ≤ 450, y = $60.

And,

if 450 < x ; y = $60 + (x - 450min) × $0.35

where we use (x - 450) ×$0.35 since any minute after the 450 minute mark is considered an extra time.

Answer: if  0 < x ≤ 450, y = $60.

if 450 < x ; y = $60 + (x - 450min)*$0.35

Step-by-step explanation:

Here x will represent the number of minutes.

with $60 you have 450 minutes, and you must pay 60 regardless of how much minutes you use.

so if  0 < x ≤ 450, y = $60.

now, if you call for more than 450 minutes, you get an additional of $0.35 per minute, then we have:

if 450 < x ; y = $60 + (x - 450min)*$0.35

where we use (x - 450)*$0.35 because any minute after the 450 minute mark is considerated an additional time.

So our piecewise function is:

if  0 < x ≤ 450, y = $60.

if 450 < x ; y = $60 + (x - 450min)*$0.35
