asambeis [7]

Midpoint = $( \frac{X2+X1}{2} , \frac{Y2+Y1}{2} )$

Plug in:

$( \frac{3+7}{2} , \frac{4+(-2)}{2} )$

Equals:

$( \frac{10}{2} , \frac{2}{2})$

Your answer is then:

ACT mathematics score for a particular year are normally distributed with a mean of 28 and a standard deviation of 2.4 points

kompoz [17]

Answer:

a. 0.1587

b. 0.8849

c. 0.1814

Step-by-step explanation:

a. Given that $\mu=28, \ \ \sigma=2.4$

-The probability a randomly selected score is greater than 30.4 is calculated as:

$P(X>30.4)=1-P(X30.4)=1-P(z$

Hence, the probability of a score greater than 30.4 is 0.1587

b. Given that $\mu=28, \ \ \ \sigma=2.4$

The probability a randomly selected score is less than 32.8 is calculated as:

$P(X$

Hence, the probability that a randomly selected score is less than 32.8 is 0.8849

c. The probability that a score is between 25.6 and 32.8 is calculated as follows:

$P(25.6$

Hence, the probability is 0.1814

A factory robot recently examined some bulbs, of which 4 were flawed and 26 were not. Considering this data, how many flawed bul

ASHA 777 [7]

Answer:

Step-by-step explanation:

Given that:

Flawed bulbs = 4

Not flawed = 26

Total examined = (flawed + not flawed)

Total examined = (4 + 26) = 30

P(flawed) = flawed / total

P(flawed) = 4 / 30 = 0.1333333

If 15 is examined :

Expected number of flawed bulbs :

(4/30) * 15 = 2
