<h3>Answer: B) none are true</h3>

Explanation:

Choice A is false because 8^1 = 7^1 becomes 8 = 7. An equation is only true if both sides are the same value (after simplifying fully).

Choice C is false because 3^2 turns into 9, while 2*2*2 is 8. In other words, 3^2 = 2*2*2 turns into 9 = 8 which is false.

Choice D is false also. The 5^3 means 5*5*5 and that turns into 125. If you wrote 5*3 on the left side, then the equation would be true.

If you want to put a 4x8 piece of plywood through a 3 foot square opening in your ceiling by turning it diagonally is the openin

Zigmanuir [339]

Here we apply the Pythagorean theorem:
c^2=a^2+b^2
The diagonal of the opening will be:
c^2=3^2+3^2
c^2=9+9
c^2=18
c=3√2 ft

The diagonal of the wood will be:
c^2=4^2+8^2
c^2=16+64
c^2=80
c=4√5 ft

The space will not be enough for the plywood to pass

enyata [817]

Answer:

0.05

Step-by-step explanation:

We can correctly state that the total sample space= 100 students

40% of 100 students exercise regularly

The probability that 5 students

Picked at random exercise regularly is

Pr(5) = 5/100= 1/20

Pr(5)= 0.05
