Answer:

Step-by-step explanation:

total size of sample = 10,000

men women

voted 2777 3466

did not vote 1444 2313

By chi square test we can find the relationship between gender and participation in the election

$X^2 = \frac{ N(ad-bc)^2}{(a+c)(b+d)+(a+b)(c+d)}$

where

a represent = 2777, b = 3466, c= 1444, d = 2313, N = 10000

Putting values to get chis square statics

$X^2 = \frac{ 10000(2777*2313-3466*1444)^2}{(2777+1444)(3466+2313)+(2777+3466)(1444+2313)}$

$X^2 = = 35.159$

A right pyramid with a square base has a base length of x inches, and the height is two inches longer than the length of the bas

vredina [299]

Answer:

The answer to your question is Volume = (1/3)(x²)(x + 2)

Step-by-step explanation:

Data

length = x

height = x + 2

Volume = ?

Formula

Volume = 1/3Ab h

Process

1.- Calculate Ab

Ab = length x length

-Substitution

= (x)(x)

-Simplification

= x²

2.- Substitution

Volume = (1/3)(x²)(x + 2) or (1/3)(x³ + 2x²)

A tourist drives 70 miles along a scenic highway and then takes a 7-mile walk along a hiking trail. The average velocity driving

san4es73 [151]

Answer: $T=\frac{17}{x}$

Step-by-step explanation:

The formula we need to use is:

$time=\frac{distance}{velocity}$

We know that "T" is the total time for driving and hiking and "x" is the average velocity on the hike.

Knowing that the tourist drives 70 miles along the scenic highway and walk 7-mile walk along the hiking trail, and also knowing that the average velocity driving is 7 times that while hiking, we can conclude that the total time is:

$T=\frac{70}{7x}+\frac{7}{x}$

Finally, simplifying the equation, we get that the total time for driving and hiking as a function of the average velocity on the hike, is:

$T=\frac{10}{x}+\frac{7}{x}\\\\T=\frac{10+7}{x} \\\\T=\frac{17}{x}$
