<span>Answer = probability that he selects exactly 2,3,4 or 5 passing plays.
prob that he selects exactly two passing plays =
(8C2)*(9*8)*
(15*14*13*12*11*10)
/(26*28*.....19)
where:
8C2 is the number of ways of choosing two slots out of 8 and
prob that he selects first passing play = 9/26
prob that he select second passing play = 10/25 etc
you can calculate the other three cases similarly and sum to obtain the answer.</span>
Answer: 228,700
Step-by-step explanation:
6352 x 36 = 228,672
228,672 + 28 = 228,700
so
228,700 / 36 = 6352 r 28
Or
228,700 - 28= 228,672
228,672 / 36 = 6352
Answer:
Natalia's work is wrong.
Step-by-step explanation:
Natalia divided a decimal number by an entire number. Since division is a operation derived from multiplication, the best approach to check if work was good is multiplying the given result by denomination, that is:
1) 
Given.
2) 
Definition of addition.
3) 
Distributive property.
4) 
Definitions of multiplication and decimal number.
5) ![x = 72 +[2\cdot (10)^{-1}]\cdot 12](https://tex.z-dn.net/?f=x%20%3D%2072%20%2B%5B2%5Ccdot%20%2810%29%5E%7B-1%7D%5D%5Ccdot%2012)
Definition of division/Associative property.

Natalia's work is wrong.
Answer:
10 cm
Step-by-step explanation:
The larger polygon is also a regular 6-sided polygon, so each side is 1/6 of the perimeter length:
(60 cm)/6 = 10 cm . . . length of a side
1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.
