In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 21% of your total grade, each major test is worth 25%, and the final exam is worth 29%. Compute the weighted average for the following scores: 60 on the lab, 81 on the first major test, 69 on the second major test, and 79 on the final exam. Enter your answer as a whole number.

Answer 1

Answer:

Answer:

$Weighted\ Average = 73$

Step-by-step explanation:

Given

$Lab = 21\%$

$Tests = 25\%$

$Exam = 29\%$

$Lab\ Score = 60$

$First\ Test = 81$

$Second\ Test = 69$

$Exam = 79$

Required

The weighted average

To do this, we simply multiply each score by the corresponding worth.

i.e.

$Weighted\ Average = Lab\ worth * Lab\ score + Tests\ worth * Tests\ score.....$

So, we have:

$Weighted\ Average = 21\% * 60 + 25\% * 81 + 25\% * 69 + 29\% * 79$

Using a calculator, we have:

$Weighted\ Average = 73.01$

$Weighted\ Average = 73$ --- approximated

Find the x-values (if any) at which f is not continuous. Which of the discontinuities are removable? (Enter your answers from smallest to largest. Enter NONE in any unused answer blanks.) f(x) = x + 3 x2 − 2x − 15

Answers

Answer:

-3 (removable), +5

Step-by-step explanation:

Maybe you have ...

$f(x)=(x+3)/(x^2-2x-15)=(x+3)/((x+3)(x-5))=(1)/(x-5)\quad x\ne-3$

This will have discontinuities (points where the function is undefined) at ...

x = -3
x = 5

The discontinuity as x = -3 is removable by defining f(-3) = -1/8.

Final answer:

The function f(x) = x + 3x² - 2x - 15 is continuous for all x-values.

Explanation:

In order to find the x-values at which the function f(x) = x + 3x² - 2x - 15 is not continuous, we need to look for points where the function has discontinuities. A function can have three types of discontinuities: removable discontinuities, jump discontinuities, and infinite discontinuities.

To find the x-values at which f(x) is not continuous, we need to check for three conditions: 1) The function is defined for all real numbers, so there are no points where f is undefined. 2) The function does not have any jump or jump-like discontinuities, which occur when the left and right limits of a point are finite but not equal. 3) The function does not have any infinite discontinuities, which occur when the left and right limits of a point are infinite.

Therefore, the function f(x) = x + 3x² - 2x - 15 is continuous for all x-values. There are no discontinuities in this function.

A rectangular window has a length of 81.47 cm and a width of 34.2 CM what is the least

Answers

The least precise measurement of the perimeter of the window is 231.30
Step-by-step explanation:
The least price measurement mean a value with the least number of significant figures.calculate the perimeter in this case as;
Perimeter of a rectangle = 2(l+w) where l is the length and w is the width
Perimeter= 2(81.47 + 34.2)
Perimeter=2(115.67)
Perimeter=231.34
Perimeter=231.30(4 significant figures)

What is the value of x in the figure?

Answers

Answer:

x=65

Step-by-step explanation:

Both sides have to equal the same, which is 145. 145-15=130, 130/2=65. So basically you have to do inverse operation to solve this.
