find the measure of m
Answers
Answer:
m=42
Step-by-step explanation:
because all straight line equal 180, we can find angle C
180-98=82
now, all triangles add up to 180. If we add up all the values we can find x
82+6x+8+5x+2=180
92+11x=180
11x=88
x=8
Now, just plug the variable into the angle measure
5(8)+2
40+2

Answers
C
have a nice day!!!!!!!!!!!!!!!!!!!!!!!
Approximately 95% of data falls within 2 standard deviations (±2) of the mean. Option D is correct.
What is a normal distribution?A normal distribution is a type of continuous probability distribution for a real-valued random variable such that the values are symmetric about a mean and the curve has bell shape.
Standard deviation is the measure of the randomness of the distribution. The curve has its peak at the mean.
As standard deviation increases, the peak of the curve comes lower and the distribution becomes more and more dispersed.
In a normal distribution 68% of the values falls within 1 standard deviation
and 95% of the values falls within two standard deviations. 99% of the values falls within three standard deviations.
Hence, approximately 95% of data falls within 2 standard deviations (±2) of the mean.

Answers
Answer:
A = 25
B = 65
Step-by-step explanation:
Remark
I hope you mean what is the size of <A? If not leave a note. If I am correct than A and C are complementary (equal 90o) since B is a right angle.
Solution
2x + 1 + 5x + 5= 90 Combine like terms
7x + 6 = 90 Subtract 6 from both sides
7x = 90-6
7x = 84 Divide by 7
x = 84/7
x = 12
==========================
Now that is not quite the answer.
A = 2x + 1
A = 2*12 + 1
A = 25
B = 5x + 5
B = 5*12 + 5
B = 60 + 5
B = 65

The probability that both are silver hoop earrings is:
Answers
Answer:
2 + 2 = 4 total earrings in the box.
If you put the earring back into the box before taking out the second, it would be 1/2 * 1/2 = 1/4, 25%.
Answer:
1/6 or 16.7%
Step-by-step explanation:
There are a total of 4 earrings in the box: 2 pairs of earrings + 2 pairs of earrings.
If you return the first earring to the box before removing the second, the answer is 1/2 * 1/2 = 1/4, or 25%.
If you remove the first earring from the package, the response is 1/2 * 1/3 = 1/6, or 16.7%.

Consider a binomial experiment with n = 5 trials where the probability of success on a single trial is p = 0.30. (a) Find P(r = 0). (b) Find P(r ≥ 1) by using the complement rule.
Answers
Answer:
0.16807 ; 0.83193
Step-by-step explanation:
Given that:
Number of trials, n = 5
Probability of success, p = 0.30
P(r = 0)
Using the binomial probability relation :
P(x =r) = nCr * p^r * (1 - p)^(n - r)
(a) Find P(r = 0).
P(r = 0) = 5C0 * 0.3^0 * (0.7)^(5- 0)
= 1 * 1 * 0.16807
= 0.16807
(b) Find P(r ≥ 1) by using the complement rule
P(r ≥ 1) = 1 - P(r = 0)
P(r ≥ 1) = 1 - 0.16807
P(r ≥ 1) = 0.83193
If three-fifths of seventh-grade class has missed at least one day of school, what percentage of 7th grade has missed at least a day of school?
Answers
The percentage of 7th grade class who has missed at least a day of school is 60 percentage.
What is percentage?
A percentage is a number or ratio expressed as a fraction of 100.
It is usually represented by using the symbol %
Given data ,
Fraction of 7th grade class that missed at least one day of school = 3 / 5
Now , to calculate the percentage of 7th grade that has missed at least one day of school , we multiply the fraction by 100
Therefore , Percentage = 3 / 5 x 100 %
= 3 x 20 %
= 60 %
Hence , the percentage of 7th grade class who has missed at least a day of school is 60 percentage.
