Answer:

a. There is a causation relationship and positive trend between number of hours on homework and higher test scores.

b. 76

Step-by-step explanation:

a. Since the dots all follow a linear progression and increase closely together this is a positive trend and likely a causation relationship.

b. y=7x+41 can predict a test score. x is the number of hours, so if 5 if the number of hours then y=7(5)+41 = 35+41=76

Semenov [28]

the volume of the sculpture is $Volume = 64.11ft^3$ .

<u>Step-by-step explanation:</u>

Here we have , An artist creates a cone-shaped sculpture for an art exhibit. If the sculpture is 5 feet long and has a base with a circumference of 21.980 feet, We need to find the volume of the sculpture . Let's find out:

We know that

⇒ $Circumference = 2\pi r$

According to question ,

⇒ $21.980 = 2\pi r$

⇒ $\frac{21.980}{2\pi} = r$

⇒ $r=3.5$

Now , We know that Volume of cone :

⇒ $Volume = \frac{1}{3}\pi r^2h$

⇒ $Volume = \frac{1}{3}(3.14) (3.5)^25$

⇒ $Volume = 64.11ft^3$

Therefore , the volume of the sculpture is $Volume = 64.11ft^3$ .
