Birth weights of babies born to full-term pregnancies follow roughly a Normal distribution. At Meadowbrook Hospital, the mean weight of babies born to full-term pregnancies is 7 lbs with a standard deviation of 14 oz (1lb = 16 oz).What is the probability that the average weight of the four babies will be more than 7.5 lbs?Would you convert the lbs. to ounces before this problem can be solved?

Prob is 0.2839

Yes should be converted to have uniform units.

Step-by-step explanation:

Given that birth weights of babies born to full-term pregnancies follow roughly a Normal distribution

Let X be the mean weight of babies born to  full-term pregnancies

X is N (7, 14/16)

We convert oz into pounds to have uniform units so that we can do arithmetical operations in that

The probability that the average weight of the four babies will be more than 7.5 lbs

= P(X>7.5)

=

step-by-step explanation:

i think you should think about the question and not look online.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
