What is the measure of ∠M?A.
53°
B.
65°
C.
81°
D.
98°
Answers
And sum of angles in a quadrilateral = 360 degrees.
The angle with no number but just a symbol = 90 degrees.
From the fourth angle been M:
Therefore: 90 + 62 + 127 + M = 360
279 + M = 360
M = 360 - 279
M = 81
M = 81°
Option C.
I hope this explains it.

Answer:
2/6 or 1/3 I think
Step-by-step explanation:
you have a 1 out of 2 chances to land tails and 1 out of 4 chance to role a 2 on the spinner. so in total there is 6 chances for rolling and flipping the coin. and there is only 1 chance for both in the odds.
therefore I believe that its is 1/3 or 2/6. I do not know if I am right exactly but that is my thought process.

Answer:
z = -3.73
Probability = P(z<-3.73) = 9.48761E.05
Step-by-step explanation:
Detailed explanation is given in the attached document.
The probability that the project will take more than 30 days to complete can be found using the NORMSDIST() function in Excel, and it depends on the z-score associated with the project's completion time distribution.
To find the probability that a project will take more than 30 days to complete using the normal distribution, you'll need to follow these steps:
1. Calculate the z-score for 30 days using the formula:
Z = (X - μ) / σ
Where:
- X is the value you're interested in (30 days in this case).
- μ is the mean completion time (expected completion time).
- σ is the standard deviation of completion times.
2. Once you have the z-score, use Excel's NORMSDIST() function to find the probability associated with that z-score.
Here's a hypothetical example of how to do this:
Let's say the expected completion time (mean) for the project is 25 days, and you have a standard deviation (σ) of 5 days. Now, calculate the z-score:
Z = (30 - 25) / 5
Z = 1
Now, use Excel's NORMSDIST() function to find the probability associated with a z-score of 1:
`=1 - NORMSDIST(1)`
This formula will give you the probability that the project will take more than 30 days to complete.
Make sure to replace the mean (25) and standard deviation (5) in the formula with the actual values from your project data. Additionally, round the z-score to two decimal places and the final answer to four decimal places, as requested in your question.

Answer:
- a = -25: -555
- a = 1: 69
- a = 10: -30
Step-by-step explanation:
Put the value where "a" is in the expression and do the arithmetic.
- For a = -25: 70 - (-25)² = 70 - 625 = -555
- For a = 1: 70 - (1)² = 70 - 1 = 69
- For a = 10: 70 - (10)² = 70 - 100 = -30

A. dL/dt = kL
B. dL/dt = 100 - kL
C. dL/dt = k(100 - L)
D. dL/dt = kL - 100
Answers
Answer:
C. dL/dt = k(100 - L)
Step-by-step explanation:
We have a list containing 100 words.
L = number of words memorized at time t.
At any time t, the number of words left to be memorized is 100-L.
Therefore:
The correct option is C.
