Answer:
Step-by-step explanation:
volume=length×width×height
V=(4x-3)(x+1)(x+2)
=(4x-3)[x²+2x+x+2]
=(4x-3)(x²+3x+2)
=4x(x²+3x+2)-3(x²+3x+2)
=4x³+12x²+8x-3x²-9x-6
=4x³+9x²-x-6
Yes, it does.
Ex:
2 + 3 = 3 +2 => 5 = 5
For negative integers:
(-2) + (-3) = (-3) + (-2) => -5 = -5
The table is missing in the question. The table is provided here :
Group 1 Group 2
34.86 64.14 mean
21.99 20.46 standard deviation
7 7 n
Solution :
a). The IV or independent variable = Group 1
The DV or the dependent variable = Group 2
b).
Therefore, 
t = -2.579143
Now, 
df = 7 - 1
= 6
Therefore the value of p :
= 0.020908803
The p value is 0.0209
So we reject the null hypothesis and conclude that

This is an awful question. They mean to say the number of hours practicing <em>per week</em> (we'll call it h) varies inversely with the <em>time</em> (t) she runs her event. Unless they mean to imply more practicing makes Tyler slower, in which case she should just get a pizza.
Inverse variation means the product is a constant, we'll call it k.
ht = k
When h = 1 hour t=6 minutes
(1)(6) = k
k = 6 (hour*minutes, but as long as we're consistent we don't need to sweat the unit.)
Decreasing her time by one minute means t = 6 - 1 = 5. We solve for h.
ht = k
h = k/t = 6/5 = 1.2 hours
Answer: 1.2 hours, second choice
