Answer:

i) ∠AOB = 87°

ii) ∠BOC = 72°

iii) ∠COD = 123°

iv) ∠AOD = 78°

Step-by-step explanation:

The first three angle measures can be read from the diagram. Find the rays that define the angle, and read the measure of the arc between them.

The last angle, AOD, is found using the fact that the sum of all of the angles around a point is 360°.

87° +72° +123° +∠AOD = 360°

∠AOD = 360° -282° . . . . . . . . . . subtract 282° from both sides

∠AOD = 78°

The IQs of 700 applicants to a certain college are approximately normally distributed with a mean of 115 and a standard deviatio

Kobotan [32]

Answer: 35

Step-by-step explanation:

Given : The IQs of 700 applicants to a certain college are approximately normally distributed with a mean of 115 and a standard deviation of 11.

i.e. $\mu=115$ and $\sigma= 11$

Let x denotes the IQs of applicants to college.

If the college requires an IQ of at least 97, then, the probability that students have IQ less than 97:-

$P(x$ [By using z-table]

Number of students will be rejected on this basis of IQ = Total students x Probability of students have IQ less than 97

= 700 x 0.0505 = 35.35 ≈ 35

Hence, about 35 students will be rejected on this basis of IQ, regardless of their other qualifications .
