Answer:
The value 4.5 is rational and the value 15−−√ is irrational. The sum of 4.5 and 15−−√ has a non-repeating and non-terminating decimal expansion. Therefore, the sum of 4.5 and 15−−√ is irrational. I can't explan but that's the correct Answer
C
If you have a graphing calculator, go to 2nd vars, normalcdf(.
Put 150 for the lower bound and 99999999 for the upper bound. You want to know the probability of all the values over 150. Put 131.8 for the mean and 29.12 for the standard deviation. Click paste.
Your answer will be .266
Answer:
They need 2 and 1/2 rolls.
Step-by-step explanation:
Area = length x width
A = l x w
A = 20 x 3
A = 60 ft²
If 60 ft² = 1 roll
What about 150 ft² = ?
= (150 x 1) ÷ 60
= 150 ÷ 60
= 2.5
= 2 and 1/2 rolls
The answer will have to be 13
