They were without electricity for 47 minutes.....determine the percent of an hr....so 1 hr = 60 minutes.....so they were out 47 out of 60 minutes...
47/60 = 0.783 = 78.3%.....so just type in 78.3 because ur not supposed to include the percent sign
Answer:
Should be 13. Sorry if I’m incorrect!
Step-by-step explanation:
Angles 1 and 2 are vertical angles which makes # 3 angle 1 = angle 2
Because angle 1 and 2 are vertical angles, then A and E would be similar due to the vertical angle theorem as well.
The answer would be D.
The probability of wearing blue shirts on both days is 3/28.
<h3>What is probability?</h3>
Probability is the measure of the likelihood of an occurrence.
Given:
8 shirts are available out of which 3 are blue, 1 is green and 2 are white.
P(blue on Monday) = 3/8
Now, 7 shirts are left to wear on Tuesday
P(blue on Tuesday) =2/7
So,
the probability of wearing blue shirts on both days = 3/8 * 2/7 = 3/28
