A government agency reports that 21% of baby boys 6-8 months old in the United States weigh less than 26 pounds. A sample of 148 babies is studied. Use the TI-84 Plus calculator as needed. Round the answer to at least four decimal places. (a) Approximate the probability that less than 38 babies weigh less than 26 pounds. (b) Approximate the probability that 36 or fewer babies weigh less than 26 pounds. (c) Approximate the probability that the number of babies who weigh less than 26 pounds is between 29 and 39 exclusive. Part 1 of 3 The probability that less than 38 babies weigh less than 26 pounds is .

i can answer this question sweetie!

step-by-step explanation:

i think the correct option is the second option.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
