Given circle P, which of the following options are major arcs?

MakcuM [25]

If your asking to select all that apply,

The formula is arc length = θ ( r ) {\displaystyle {\text{arc length}}=\theta (r)} , where equals the measurement of the arc's central angle in radians, and r {\displaystyle r} equals the length of the circle's radius. Plug the length of the circle's radius into the formula.

Can you guys give me the working out and the answers?

Mice21 [21]

#1 (15)

50%= 1/2

1/2 of 30 is the same as 30÷2=15

#2 (20kg)

25%= 1/4

1/4 of 80 is the same as 80÷4= 20

#3 (30cm)

1/3 of 90 is the same as 90÷3=30

#4 (8m)

2/3 of 12 is the same as 12÷3= x2

12÷3= 4(2)= 8

#5 (70)

10% = 1/10

1/10 of 700 is the same as 700÷10= 70

#6 (280)

40%= 4/10

700÷10=x(4)

70(4)=280

#7 (2700 m)

9/10

3000÷10=x(9)

300(9)= 2700

Suppose that the scores of a history test are normally distributed with a mean of 565 and a standard deviation of 113. a) What p

zvonat [6]

Answer:

15.39% of the scores are less than 450

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 565, \sigma = 113$

What percentage of the scores are less than 450?

This is the pvalue of Z when X = 450. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{450 - 565}{113}$

$Z = -1.02$

$Z = -1.02$ has a pvalue of 0.1539

15.39% of the scores are less than 450
