A chemistry professor suspects that there is a relationship between the number of classes a student misses and that student’s sc

ore on the final exam (from 0 to 100%). The professor chooses a random sample of students in Introduction to Chemistry and collects data about each student’s final exam score and number of missed days of class. Which of the following is the most appropriate statistical test to use to determine if there is a relationship between number of missed classes and final exam scores? Matched pairs ANOVA Inference for regression Chi-squared test for independence Two-sample t-test

Answer:

Interference for regression

Explanation:

Interference for regression is the most suitable statistical test to use to find out if there is any link between number of missed classes and the final test scores.

Because those two variables are related and student test score can be predicted using number of classes that are missed.

Answer:

A. Circular base of the bucket

B. Bucket

Step-by-step explanation:

We are given that,

1. The dimensions of the rectangular prism are,

Length = 2 feet, Width = 3 feet and Height = 5 feet.

So, we have,

Area of the rectangular base = Length\times Width

i.e. Area of the rectangular base = 2\times 3

i.e. Area of the rectangular base = 6 feet²

Also, we have,

Volume of the prism = whl

i.e. Volume of the prism = 3\times 5\times 2

i.e. Volume of the prism = 30 feet³

2. The dimensions of the cylinder are given as,

Diameter = 3 feet i.e Radius = \frac{3}{2} = 1.5 feet

Height = 5 feet

Then, we have,

Area of the circular base = \pi r^2

i.e. Area of the circular base = \pi (1.5)^2

i.e. Area of the circular base = 2.25\pi

i.e. Area of the circular base = 7.07 feet²

Also, we have,

Volume of the cylinder = \pi r^{2}h

i.e. Volume of the cylinder = \pi (1.5)^{2}\times 5

i.e. Volume of the cylinder = \pi 2.25\times 5

i.e. Volume of the cylinder = 11.25\pi

i.e. Volume of the cylinder = 35.34 feet³

PART A: Since we have,

Area of the rectangular base = 6 feet² < 7.07 feet² = Area of the circular base

Hence, the circular base of the bucket is larger in area.

PART B: We have,

Volume of the prism = 30 feet³ < 35.34 feet³ = Volume of the cylinder

Hence, the bucket is larger in volume.

Question 2<br> What is the product of 3 – 5i and 2 + 7i ?
Naya [18.7K]

Answer:

41 + 11i

Step-by-step explanation:

Note that i² = - 1

Given

(3 - 5i)(2 + 7i) ← expand using FOIL

= 6 + 21i - 10i - 35i² ← collect like terms

= 6 + 11i + 35

= 41 + 11i
