Maddie earned an 88 on her first test and an 80 on second test. What is her average test score

Answers

Answer 1

Answer:

Step-by-step explanation:

the average can be found by adding up all ur numbers and dividing by how many numbers u have

so her average test score is : (88 + 80) / 2 = 168/2 = 84 <==

Answer 2
Final answer:

To find Maddie's average test score, add up her scores (88+80=168) and divide by the number of tests (2). This gives us an average of 84.

Explanation:

The subject of this question is Mathematics, specifically the concept of calculating averages. To calculate Maddie's average test score, you'll need to add up the scores she received and then divide the sum by the number of tests she took.

In this case, Maddie earned an 88 on her first test and an 80 on her second test. You would add these two scores together (168), then divide by 2 (since she took 2 tests), which gives us an average of 84.


So, Maddie's average test score is 84.

The maximum value of y=√(x+2)-1 on the interval [-2 ,2]

Answers

I love calculus! Let’s begin with finding the derivative of y.

y’ = (1/2)(x+2)^(-1/2)(1)
y’ = 1/(2 √(x+2))

Now to find the maximum or minimum, you need to check the end-points of the interval and when y’=0.

There is no instance where y’ will be equal to 0, so you just need to check the endpoints.

When x= -2, y= -1. When x= 2, y= 1.

There is an absolute maximum of 1 when x = 2

There is an absolute minimum of -1 when x = -2

Answer:

  1

Step-by-step explanation:

The square root function is monotonically increasing, so will have a maximum at the right end of any interval. Here the maximum is at x=2. That value is ...

  y = √(2+2) -1 = 2 -1 = 1

The maximum value on the interval is 1.

What is the inverse of the function g(x) = -3(x+6)?

Answers

Answer:

g-1(x) = -x/3 - 6.

Step-by-step explanation:

Let g(x) = y = -3(x + 6)

y = -3x - 18

3x = - y - 18

x =  -y/3 - 6

Now replace x by the inverse g-1(x)  and y by x, so

g-1(x) = -x/3 - 6.

The store bought a pair of shoes for $50, and sold it for $80.What percentage was the mark up

Answers

The markup percentage on the shoes that were bought for $50 and sold for $80 is 60%.

To calculate the markup percentage, you subtract the original cost from the selling price and then divide that number by the original cost. Finally, you multiply the result by 100 to get the percentage.

The formula looks like this: ((Selling Price - Original Cost) / Original Cost)×  100. Let's apply this formula to your question.

The store bought the shoes for $50 and sold them for $80. So the markup in dollars is

$80 - $50 = $30

Now, let's convert this to a percentage:

Markup Percentage =

[tex]= \frac{80-50}{50} \times 100 \\\\= \frac{30}{50} \times100\\\\ = 60\%[/tex]

The markup percentage is 60%.

68 degrees

69 degrees


Answer: 68

Answers

Answer:

69°

Step-by-step explanation:

The three interior angles in a triangle will always add up to 180°, so we have:

43°+x+(x-1)=180°

43°+2x-1°=180°

2x=180°-43°+1°

2x=138°

x=69°

Andy cut a tuna and a chicken sandwich into a total of 18 pieces. He cut the tune into 12 more pieces than the chicken. Andy are 5 pieces of the tuna. What fraction of the tuna did he eat?

Answers

5/12 pieces of tuna I think, you can’t simplify it into anything less.

The fraction is 5/15, which simplifies to 1/3. So Andy ate one third of the tuna sandwich.

The student's question involves determining the fraction of the tuna sandwich that Andy ate. Andy cut a tuna sandwich into 12 more pieces than the chicken sandwich and the total number of pieces was 18. Since tuna has 12 more pieces, we let the number of chicken pieces be x. Hence, the tuna pieces would be x + 12. The equation then is x + (x + 12) = 18. Solving this, we get x = 3 (chicken pieces) and x + 12 = 15 (tuna pieces).

Andy ate 5 pieces of the tuna sandwich, so the fraction of the tuna he ate is 5 out of the total tuna pieces, which is 15. Therefore, the fraction is 5/15, which simplifies to 1/3. So Andy ate one third of the tuna sandwich.

Final answer:

The ratios for sin C, cos C, and tan C in a right triangle are y/h, x/h, and y/x respectively, where y is the opposite side, x is the adjacent side, and h is the hypotenuse.

Explanation:

To write ratios for sin C, cos C, and tan C in a right triangle, you need to refer to the lengths of the sides of the triangle relative to angle C. If we denote the opposite side to angle C as y, the adjacent side as x, and the hypotenuse as h, the ratios are defined as follows:

sin C = opposite/hypotenuse = y/hcos C = adjacent/hypotenuse = x/htan C = opposite/adjacent = y/x

In a practical scenario, if you know the magnitude of one side and the direction angle, you can use these ratios to find the scalar components of a vector in a coordinate system, solve problems involving the Law of Sines and Law of Cosines, or analyze wave functions in physics. For example, the Law of Sines relates the lengths of the sides of a triangle to the sines of its angles as follows:


 a/sin A = b/sin B = c/sin C

Where a, b, and c are the sides of the triangle opposite to angles A, B, and C, respectively.

Which statement describes the behavior of the function f (x) = 3x/4-x
The graph approaches –3 as x approaches infinity.
The graph approaches 0 as x approaches infinity.
The graph approaches 3 as x approaches infinity.
The graph approaches 4 as x approaches infinity.

Answers

Answer:

A. The graph approaches –3 as x approaches infinity.

Step-by-step explanation:

when looking at the problem F (x) + 3x/x-4 the answer would lead up to..

Finding the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain:  

( − ∞ , 4 ) ∪ ( 4 , ∞ ) , { x | x ≠ 4 }

Range:  ( − ∞ , − 3 ) ∪ ( − 3 , ∞ ) , { y | y ≠ -3 }

are what it leads to and seeing the range -3 would have x as infinite/ -∞

so A is the correct option to me

The statement that describes the behavior of the function f(x) = 3x/4-x is The graph approaches 0 as x approaches infinity.

Option B is the correct option.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The statement "The graph approaches 0 as x approaches infinity" is the correct statement that describes the behavior of the function f(x) = 3x/(4-x).

We can use the limit definition of approaching infinity.

When x becomes very large (positive or negative), the term 4 - x in the denominator becomes very small, approaching zero.

As a result,

The fraction 3x/(4-x) approaches zero as x approaches infinity.

This can be confirmed using L'Hopital's rule, which gives the limit of the function as 0/1, or simply by observing the graph of the function.

Thus,

The graph approaches 0 as x approaches infinity.
