Answer:
Step-by-step explanation:
<h3>
Sphere:</h3>
1) a) r = 7 cm



= 4*3.14 * 7 * 7
= 615.44 cm²
b) r= 8.4 cm


Surface area = 4*3.14*8.4*8.4
= 887.04 cm²
<h3>Hemisphere:</h3>
a) r = 6 cm




= 3 * 3.14 * 6 * 6
= 339.12 cm²
A) Yes, the two events are independent because P(NF|PB) = P(NF).

Answer:
Distributive property
Step-by-step explanation:
In order to solve this equation we first need to distribute 3 into 2y+5, we use the distributive property to do this.
<span>The range would be all real numbers such that 0 ≤ y ≤ 40.
