Answer:
34; 34 inches is not long enough
Step-by-step explanation:
A doormat is the shape of a rectangle and its area uses A=l*w. If the area is 714 and its length is 21, then 714 = 21*w. Solve for w.
714=21w
714/21= 21w/21
34 = w
Answer:
a. 0.158
b. 0.01942
Step-by-step explanation:
For part a we define probability that the randomly selected person is if 65 years or more than that
a.
Probability of under age = 22.8% = 0.228
Probability of those from age 18 to 64 = 61.4% = 0.614
1-0.228-0.614
= 0.158
b.
P(uninsured) = p(those not up to 18) * p(those uninsured or under 18) + p(those age 18-64) * p(uninsured or under 18) + p(being 64plus) x P(uninsured or 64 plus)
= 0.228 x 0.051 + 0.614 x 0.124 + 0.158 x 0.011
= 0.011628 + 0.076136 + 0.001738
=0.089502
P(65 of older|uninsured) = p(64+) x P(uninsured or 64 plus)
= 0.157 x 0.011/0.089502
= 0.001738/0.089502
= 0.01942
The answer is C) 20°. This is because 73 + 87 = 160, and there are 180° in a triangle so 180 - 160 = 20. I hope this helps!
