suppose the people have weights that are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.
Find the probability that if a person is randomly selected, his weight will be greater than 174 pounds?
Assume that weights of people are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.
Mean = 177
standard deviation = 26
We find z-score using given mean and standard deviation
z =
=
=-0.11538
Probability (z>-0.11538) = 1 - 0.4562 (use normal distribution table)
= 0.5438
P(weight will be greater than 174 lb) = 0.5438
There's no if about it,
has a zero
so
is a factor. That's the special case of the Remainder Theorem; since
we'll get a remainder of zero when we divide
by
At this point we can just divide or we can try more little numbers in the function. It doesn't take too long to discover
too, so
is a factor too by the remainder theorem. I can find the third zero as well; but let's say that's out of range for most folks.
So far we have
where
is the zero we haven't guessed yet. Again we could divide
by
but just looking at the constant term we must have
so
We check
We usually talk about the zeros of a function and the roots of an equation; here we have a function
whose zeros are

Ok for the 1st and 2nd paragraph, each person will need to pay 20 dollars each. For the 3rd paragraph, you could say your favorite restaurant is McDonalds. For you, you could have a strawberry milkshake, medium fries, and a Big Mac. For your second friend, they could have a coca cola, a salad, and large fries. For your third friend, they could have a lemonade, lettuce hamburger, and chocolate ice cream. For your fourth friend, they could have a Oreo Mc flurry, chicken nuggets, and small fries.
Restaurant name: McDonalds
Price: 59.99/60.00
Cost of each persons order: you pick
Each person should leave 5 dollars as a tip.
The total including tip: 79.99/80.00
Each person will pay 15.00
I dont know the last one sorry
Rachel enjoys exercising outdoors. Today she walked 5 2/3 miles in 2 2/3 hours. What is Rachel's unit walking rate in miles per hour and in hours per miles? 5 2/3 / 2 2/3 = 17/3 / 8/3 = 17/3 x 3/8 = 17/8 = 2 1/8 miles per hour.
