At a ski area in northern Vermont, the daytime high temperature in January is normally distributed with a mean of 22°F and a standard deviation 10°F. What is the probability that a randomly selected day in January will have a daytime high of A. greater than 45°F?
B. between 30°F and 40°F?
C. lower than 15°F?

the first option is the answer.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

8(1/6)

step-by-step explain:

49/6= 48

8 (1/6)

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.
