All u need to do is cube all the numbers in the domain
Answer:
2(2r + 1)(2r - 5)
Step-by-step explanation:
Given
8r² - 16r - 10 ← factor out 2 from each term
= 2(4r² - 8r - 5)
To factorise the quadratic
Consider the factors of the product of the coefficient of the r² term and the constant term which sum to give the coefficient of the r- term.
product = 4 × - 5 = - 20 and sum = - 8
The factors are + 2 and - 10
Use these factors to split the r- term
4r² + 2r - 10r - 5 ( factor the first/second and third/fourth terms )
= 2r(2r + 1) - 5(2r + 1) ← factor out (2r + 1) from each term
= (2r + 1)(2r - 5), so
4r² - 8r - 5 = (2r + 1)(2r - 5) and
8r² - 16r - 10 = 2(2r + 1)(2r - 5) ← in factored form
Answer:
Step-by-step explanation:
Hello!
The hypothesis tested where that "adds produce no change" symbolically p=0.7 versus "negatives are below 70%" symbolically: p < 0.70
So the hypothesis tested where:
H₀: p=0.7
H₁: p < 0.70
After conducting the analysis the p-value was 0.291
To decide over a hypothesis test using the p-value you have to compare it with the significance level of the test. The decision rule is the following:
If p-value > α, the decision is to not reject the null hypothesis.
If p-value ≤ α, the decision is to reject the null hypothesis.
Let's say the significance level of the test is α= 0.05
Using this level the decision is to nor reject the null hypothesis.
This means that after the political ad campaign the proportion of negatives hasn't changed.
I hope it helps!
Since you multiple the -8 points you earned on each of the 4 turns times the number of terms, -8 times 4 is -32. Your score would be -32
Answer:
P=p1+p2+p3+p4
P1=4*a=4*8=24
P2=a+b+c=6+10+8=24
P3=2*a+2*b=2*10+2*20=60=P4
P=24+24+60+60=160cm
