vovikov84 [41]

Answer:

D. If the P-value is large, reject the null hypothesis of no interaction. Conclude that there is an interaction effect.

Step-by-step explanation:

If p value is smaller than significant level(5% or 1%), then reject the null hypothesis.

From the given information about two way ANOVA, First 3 are true statements based on decision rule.

4th statement is false, becasue p value is larger, then decision is to fail the null hypothesis and conclude that there is no interaction between them

Answer:

a₄ = - $\frac{27}{2}$

Step-by-step explanation:

In a geometric sequence, the common ratio r is calculated as

r = $\frac{a_{2} }{a_{1} }$ = $\frac{a_{3} }{a_{2} }$ , substitute values

$\frac{2x+2}{x}$ = $\frac{3x+3}{2x+2}$ ( cross- multiply )

(2x + 2)² = x(3x + 3) ← expand both sides

4x² + 8x + 4 = 3x² + 3x ( subtract 3x² + 3x from both sides )

x² + 5x + 4 = 0 ← in standard form

(x + 1)(x + 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 4 = 0 ⇒ x = - 4

However x ≠ - 1 as this would make the denominator of the second term equal to zero and therefore undefined.

Thus x = - 4 and

r = $\frac{2(-4)+2}{-4}$ = $\frac{-8+2}{-4}$ = $\frac{-6}{-4}$ = $\frac{3}{2}$

Then

a₁ = - 4

a₂ = - 4 × $\frac{3}{2}$ = - 6

a₃ = - 6 × $\frac{3}{2}$ = - 9

a₄ = - 9 × $\frac{3}{2}$ = - $\frac{27}{2}$

Joyce paid $15.00 for an item at the store that was 70 percent off the original price. What was the original price?

TEA [102]

So we know that $15 was 70% of the original. We can then cross multiply and divide (15 x 100 ÷ 70) The answer you get is 21.4285714 which then rounded is $21.43!! I hope this helped!

Margarita [4]

Answer:

$26.25

Step-by-step explanation:

First, divide $15.75 by 3 to find how much it costs for one bag of cat food.

Then, multiply the result (which is $5.25) by 5 and your answer is $26.25
