RSTU and R'S'T'U' are equidistant from this line
Answer:
mean =503.75
median=400
mode=400
range=691
Step-by-step explanation:
mean= 211+351+359+400+400+659+748+902=4030/8= 503.75
range= highest number -lowest number = 902-211=691
median= 400+400 =800/2= 400
Answer:
She sold 39 tall candies and 52 short candies
Step-by-step explanation:
x is all the tall candies
y is all the short candies
x+y=91
8x+5y=572
Use the method of Substitution to find out both x and y.
x=91-y
8(91-y)+5y=572
728-8y+5y=572
728-3y=572
3y=156
y=52
x+52=91
x=39
