F(x)=2(5x+7) find f(-2)

Mathematics

Oh how fun, functions!! You substitute f(-2) into your starting function so it will look like this:
f(x)=2(5x+7)
f(x)=10x+14
f(-2)=10(-2)+14
f(-2)=(-20)+14
f(-2)=(-6)
divide by negative 2 on each side to find f:
f=3
Hope this helped!!

Reject Null Hypothesis given that  P-value < ∝

Step-by-step explanation:

Applying the Five ( 5 ) step model and assuming ∝ = 0.05

First step : determine the Null hypothesis

H0 : Age and support for Anti-smoking = independent

Second step : Determine the alternate hypothesis

Ha : Age and support for Anti-smoking ≠ independent

Thirdly : Identify significance level ( ∝ ) = 0.05

4th step : Calculate the Test statistic and P-value

Chi-squared test = 36.1429 using excel function

P-value =  1 - CHISQ.DIST(36.1429, 1, TRUE)  < 0.0001

finally : we can conclude that Age and support for Anti -smoking are not Independent hence we Reject The Null hypothesis. Given that

P-value < ∝
