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
<span>This question, in my opinion, is not well stated. If f(x) = √x, as the question statement seems to say, then the domain is not x<7. Rather, the domain is x≥0.
If f(x) is not the square root function, but say f(x) = √(7-x) then the domain is x≤7, and for this function then the appropriate answer is d), since the x-term inside the radical has a negative coefficient.</span>
7x+55=90 angle in a rectangle is
7x=90-55 90
7x=35
x=35/7
x=5
Adolescences is the answer
To solve this problem, the formula can be used
I = P / T
Where I is the fraction of the sample
P is the amount of the sample
T is the total amount of sample
Since P = 252 chicken sandwiches and I = 0.55
And solve for T
T = 252 / 0.52
<span>T = 458 sandwiches in total</span>
