To evaluate, substitute x= -2 into the equation 
.
Answer:
The stickers are divided by groups of
2/10, 3/10 and 5/10
2/10 * 70 = 14
3/10 * 70 = 21
5/10 * 70 = 35
14 + 21 + 35 = 70
So, the stickers are allotted to the 3 children in a group of
14 to one child, 21 to another child, and 35 to the third child.
Step-by-step explanation:
Let r = usual driving rate
let t = usual driving time
We need to figure out t
The distance she covers in her usual time at her usual rate is r*t
The distance she covers in her new time at her new rate is:
(1+t)*((2/3)r)
Set this equal to each other and solve for t.
rt = (2/3)r + (2/3)rt
(1/3)rt = (2/3)r
(1/3)t = (2/3)
t = 2
So her usual time is 2 hours. (There's probably a faster way to do this)

Rudra should have collected the students equally both from football and pump basketball
Answer:
P=2.326
Step-by-step explanation:
Raw Score (X):=1000
Population Mean (μ):=460
Standard Deviation (σ): =Sqrt(npq)
Where n=1000, p=460/1000=0.46 and q=1-0.46=0.54
Sqrt(npq)=sqrt(460X0.54)=15.7607
Z = (X - μ) / σ
Z = (1000 - 460) / 15.7607
Z = 34.26244
For p-value 0.01
P(x=0.01) = 2.32635
Hence, P=2.326 t 3 decimal places.
