Answer:
With the information given in the question, the blank spaces are filled thus:
Step-by-step explanation:
1. The <u>intercept </u>is the estimated amount of a purchase, if time spent viewing the online catalog was zero minutes.
2. The <u>slope coefficient</u> is the estimate of amount that a purchase charges/changes, for one extra minute spent viewing the online catalog.
3. The <u>proportion</u> of total variation in purchases that can be explained by variation in the minutes spent viewing an online catalog is equal to the <u>coefficient of determination</u>.
4. The p-value is the <u>probability value</u>
5. <u>Reject</u> the null hypothesis if there is <u>sufficient </u>evidence to support the claim that the regression slope coefficient is not equal to zero.
NOTE: In the case of number 5, the assumption is that;
Null Hypothesis: The regression slope coefficient = 0
Alternative Hypothesis: The regression slope coefficient ≠ 0
Other answers require numerical information and full data, in order to be computed or calculated.

Answer:
The solution to the system is (-2 1/3, -2 2/3)
Step-by-step explanation:
Answer:
5.5 or 5 1/2
Step-by-step explanation:
In order to solve this problem, we first need to set up an equation. Line AB is tangent to circle P. So is line AC. Because these two tangent lines come together at a point, they are congruent, or equal to each other. Now that we know this, we can set up an equation in order to solve for the value of y.
3y + 4 = 11y
Now solve for y.
- 3y - 3y
4 = 8y
÷8 ÷8
y = 0.5 or 1/2
Now that we know what the value of y is, we can plug that number into the AB equation to figure out what the measurement of line AB is.
3(0.5) + 4 =
1.5 + 4 =
5.5 or 5 1/2
We now know the measurement of line AB. I hope this helps and isn't too confusing. Please let me know if you need any more help. Good luck!
