Daniel wants to have a 90 average in his math class at the end of the year. He is trying to determine what he needs to get on his final exam, which accounts for 10% of his grade, for this to work. Tests are weighted 50% of the grade, and he currently has a 85 for his test average; quizzes are weighted 15% of his grade, and he currently has a 95 quiz average; homework is weighted 15% of his grade and he currently has a 98 homework average; and projects are weighted 10% of his grade and he currently has a 92 project average. What is the lowest whole percentage Daniel can make on his final exam for him to end up with a 90 in the class?

Answers

Answer 1

Answer: Exam + Tests + Quizzes + HW + Projects = 90

Exam = 10% * grade (x) = 0.1 * x

Tests = 50% * 85 = 0.5 * 85 = 42.5

Quizzes = 15% * 95 = 0.15 * 95 = 14.25

HW = 15% * 98 = 0.15 * 98 = 14.7

Projects = 10% * 92 = 0.1 * 92 = 9.2

Exam + Tests + Quizzes + HW + Projects = 90

(0.1 * x) + 42.5 + 14.25 + 14.7 + 9.2 = 90

(0.1 * x) + 80.65 = 90 (subtract 80.65 from each side)

(0.1 * x) = 9.35 (divide 0.1 from each side)

(0.1 * x)/0.1 = 9.35/0.1

x = 0.935

The answer is 93.5%

Which of the following represents the probability that someone whoworks full time has more than $5,000 in credit card debt?
(A) P(full time and credit card debt over $5,000)
(B) P(full time or credit card debt over $5,000)
(C) P(full time credit card debt over $5,000)
(D) P(credit card debt over $5,000 | full time)
(E) P(full time)*P(credit card debt over $5,000)

Answers

Answer:

The correct option is;

(E) P(full time) × P(credit card debt over $5,000)

Step-by-step explanation:

The given parameters are;

The mode of employment of a person = Full time

The amount of debt in the credit card = More than $5,000

The probability that a person works full time = P(full time)

The probability that the person has over $5,000 in credit card debt = P(credit card debt over $5,000)

Therefore, the probability that someone who works full time has more than $5,000 in credit card debt = P(full time) × P(credit card debt over $5,000)

How to solve this math 3-3x6+2=

Answers

The value of the expression 3-3x6+2 is -13.

What is Expression?

An expression is combination of variables, numbers and operators.

The given expression is 3-3x6+2

Three minus three times of six plus two.

The operators in the expression are plus and minus which are of addition , subtraction and multiplication.

To solve this equation, we need to first multiply 3 and 6, 3×6

which is 18.

we subtract 18 from 3, which is -15.

3-18+2

5-18

When eighteen is subtracted from 5 we get minus thirteen.

-13

Hence, the value of the expression 3-3x6+2 is -13.

Lets change the equation.
3 -(3*6) +2 Multiply 3*6 first and get 18
3 -18+2 - Same as 3-(18)+2
-15 +2 3 -18 is the same as doing 18 -3, but with the negative
Do the same to -15 +2

Answer is -13

Functions f(x) and g(x) are both increasing. In addition, the range of g is in domain of f. Prove that composite function f(g(x)) is increasing

Answers

f: D -> E;
g: F -> G, where, g(F) is in D;

Let be x1, x2 ∈ F, with x1 < x2;
But, g(x1) < g(x2), because g is increasing; => f(g(x1) < f(g(x2) , because f is increasing =>
f(g(x) is increasing.

Find the inverse.

Answers

Answer:

The inverse of this equation would be f(x) = x/-4

Step-by-step explanation:

In order to find any inverse, start by switching the x and f(x) values. After doing this, you can solve for the new f(x) value and that will be your inverse.

f(x) = -4x

x = -4f(x)

x/-4 = f(x)

f(x) = x/-4
