Answer:
Number sentences can be true or they may not be true. For example: 10 + 5 = 15. ... So, a number sentence contains numbers, mathematical operations, equal to or inequality sign and a number after the equality or inequality sign.
Step-by-step explanation:
With "infinite" numbers of successive random samples, the mean of the sampling distribution is equal to the population mean .As the sample sizes increase, the variability of each sampling distribution decreases so that they become increasingly more leptokurtic.
Y² + 10z - 10y - yz = (y - 10)(y - z)
Yesterday's time: t = 2 hr 20 min
Today's time: 0.73(2 hr 20 min) = 0.73 (2.333 hr) = 1.703 hr
This can be expressed in hours and minutes:
60 min
1 hr + 0.703 hr = 1 hr + 0.703 hr * --------------
1 hr
= 1 hr + 42.18 min
Rounded off to the nearest minute, we get 1 hr 42 min (answer)
The perimeter (P) of the rectangle is the sum of twice is length (L) and twice its width (W),
P = 2L + 2W
Substituting the known values, with either of the givens being length and width,
P = 2 x 84 ft + 2 x 50 ft = 268 ft
Thus, the answer is letter A. 268 feet.
