If a regression analysis shows an R factor of 0.15, it is safe to assume a perfect positive relationship between cost and volume

saw5 [17]

Answer:

a very weak relationship between cost and volume

Step-by-step explanation:

The R factor is used to access the strength of the relationship between a dependent and independent variable. The R factor ranges between - 1 and 1. With negative values depicting a negative linear relationship and positive values meaning a positive relationship. The closer the R factor is to - 1 or + 1, the greater the strength, a value of 0 means, no correlation exists.

Hence, a R factor of 0.15 depicts a positive but very weak relationship between cost and volume as the R value is close to 0.

1/5x-2/3y=30 when y=15

dolphi86 [110]

Answer:

Step-by-step explanation:

<u>Step 1: Set y to 15 and solve</u>

<u /> $\frac{1}{5}x - \frac{2}{3}*15=30$

$\frac{1}{5}x-10=30$

<em>Add 10 to both sides</em>

<em /> $\frac{1}{5}x-10+10=30+10$

$\frac{1}{5}x=40$

<em>Multiply both sides by 5</em>

<em /> $\frac{1}{5}x*\frac{5}{1}=40*\frac{5}{1}$

$x=200$

Answer: $x=200$

iragen [17]

Answer:

$H_A: P_{\text{Internet}}-P_{\text{Store}} > 0.10$

Step-by-step explanation:

We are given the following in the question:

Let $P_{\text{Internet}}$ be the proportion of the internet sales and $P_{\text{Store}}$ be the proportion of the store sale.

Hypothesis:

We have to conduct a hypothesis to check that the Internet sales are more than 10 percent higher than store sales.

Thus, we can design the null and alternative hypothesis as:

$H_{0}: P_{\text{Internet}}-P_{\text{Store}}\leq 0.10\\H_A: P_{\text{Internet}}-P_{\text{Store}} > 0.10$

Alternate Hypothesis:

The alternate hypothesis states that the proportion of the internet sales is greater than the proportion of store sales by 10 percent.
