i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

yes.. it's proven to be 36.

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
