7.5 7 2/5 7.69 in order
Answer:
ok for this problem lets convert all of the number into decimals to make it easier.
7.5 is already a decimal
7 2/5 as a decimal is 7.4
7.69() is already a decimal
ok so 7.4 is lowest
7.5 is next
7.69 is highest
Answer:
In order from least to greatest is [tex]7\frac{2}{5},7.5,7.69[/tex]
Step-by-step explanation:
In order from greatest to least is the other way around
[tex]2/5 = 0.4[/tex]
So [tex]7.4[/tex]

With a certain medical insurance policy, the customer must first pay an annual $250deductible, and then the policy covers 70% of the cost of x-rays. The first insurance claims for a specific year submitted by a person are for two x-rays. The first x-ray cost $700, and the second x-ray cost $950. How much, in total, will he need to pay for these x-rays?
I got $345, but it's wrong.
Answer:
$495 (745 if you include the $250 deductible)
Step-by-step explanation:
70% of 700 is 490
700 - 490 = 210
70% of 950 is 665
950 - 665 = 285
210 + 285 = $495
Answer:
495
Step-by-step explanation:
70% of 700= 490
700 - 490= 210
70% of 950= 665
950 - 665= 285
Add them together
210 + 285= 495
The reason you might have gotten 345 is because you subtracted 495 with 250 but 250 is how much he has to pay for the medical insurance, not how much he also get off

The slope f '(x) at each point (x, y) on a curve. y = f (x) is given along with a particular point (a, b) on the curve. Use this information to find f (x).
[CLO-3] f '(x) = 9 x 2 + 4 x - 4; (0, -7)
Answer:
Step-by-step explanation:
Integrating each term with respect to x, we get:
x^3 x^2
f(x) = 9--------- + 4------- - 4x + C
3 2
We are told that if x = 0, f(x) = -7, and so C must equal - 7.
The solution is
x^3 x^2
f(x) = 9--------- + 4------- - 4x - 7, or f(x) = 3x^3 + 2x^2 - 4x - 7
3 2

Answer:
x ∈ {π/18, 5π/18, 13π/18, 17π/18, 25π/18, 29π/18}
Step-by-step explanation:
Using the trig identity ...
cos(2x) = 1 -2sin²(x)
we can rewrite the equation as ...
(1 -2sin²(3x)) -5sin(3x) +2 = 0
2sin²(3x) +5sin(3x) -3 = 0 . . . . . standard form
(sin(3x) +3)(2sin(3x) -1) = 0 . . . . factored form
There are no real values of x that will make the first factor zero. The second factor is zero when ...
sin(3x) = 1/2
3x = arcsin(1/2) +2nπ or (2n+1)π -arcsin(1/2)
x = 1/3(π/6 +2nπ) or 1/3((2n +1)π -π/6)
x = (12n+1)π/18 or (12n+5)π/18
x ∈ {π/18, 5π/18, 13π/18, 17π/18, 25π/18, 29π/18}

A researcher wants to calculate the average variability from the mean of the scores in their normally-distributed data set. For each participant, they calculate a deviation score. The researcher then sums all the deviation scores together and is surprised to find that the average deviation from the mean in the group is zero. Which of the statements below is FALSE about this scenario?
A. Deviation scores can be used to calculate sum of squares, variability, and then standard deviation.
B. Approximately the deviation scores will be positive and half will be negative.
C. Deviation scores are calculated by subtracting the participant score from the mean.
D. Average deviation from the mean in the group must be squared to be meaningful.
Answer:
D. Average deviation from the mean in the group must be squared to be meaningful.
Step-by-step explanation:
The average variability from mean is not calculated with mean square of the selected group. The deviation scores calculated by subtracting participant score from the mean.

3 Connor is painting a superhero with this belt buckle shown. What is the area of the belt buckle in square Inches? 9 inches 2.5 inches 4 inches 5 inches 15 inches 2.5 mches The area in square Inches is:
HELP PLSSS
Answer:
87.5 square inches
Step-by-step explanation:
(For Diagram,Please Find in Attachment)
Given, in diagram of the belt Knuckle there are 4 Triangles (2 are of same dimensions & another 2 are of same dimensions) and a Rectangle .
Now For Area of belt Knucle, We have to First Calculate the area of 4 triangles and Area of Rectangle.
∴ Area of 2 Triangle with given dimensions ( height = 2.5 inches & base = 9 inches )
Area = 2×(1/2×b×h) ⇔ 2×(1/2×9×2.5)
Area= 22.5 square inches
∴ Area of another 2 triangle with given dimensions ( height = 5 inches & base = 4 inches )
Area = 2×(1/2×b×h) ⇔ 2×(1/2×4×5)
Area= 20 square inches
∴Area of Rectangle with given dimensions ( Length = 9 inches & Width = 5 inches )
Area= length × Width ⇔ 9×5 ⇒ 45 square inches
Now, Area of belt Knucle=Sum of Area of 4 Triangles + Area of Rectangle
Area of belt Knucle = 87.5 square inches

In a math class, 9 pupils receive a grade of 90. If 18% of the class got 90, how many pupils are there in a class?
Answer:
Let the total number of pupil be x.
Given that,
Number of pupils that received a grade of 90=9
Percentage of pupil that receive a grade of 90=18%
So,
18% of x=9
18x/100=9
x=50
Hence, there are 50 pupils in the class.

Which of the following is most likely next in the series?
Answer:
B.
Step-by-step explanation:
Judging by the picture, it appears that you are correct. The pattern seems to go as follows:
1. Blue (with one line)
2. Red (with two lines)
3. Blue (with three lines)
This means that your final step should be red with four lines, and we can eliminate D as there is no sign that the line should branch off that way (based on the pattern that we already have). Hope this helps and please let me know if you still need help!
Write a polynomial that represents the area of the above football field.
Answer:
36x² + 24x + 300 ft²
Step-by-step explanation:
→ Area of rectangle = Length × Width
→ Area of rectangle = (12x + 8) ft × (3x + 15) ft
→ Area of rectangle = 12x(3x + 15) + 8(3x + 15) ft²
→ Area of rectangle = 36x² + 180 + 24x + 120 ft²
→ Area of rectangle = 36x² + 24x + 300 ft²

a) The number of plain coasters bought and the cost of the coasters.
b) The number of coasters with a logo bought and the price of the coasters.
c) Is either coaster relationship proportional? Explain in writing how you know.
d) Explain what the unit rate of the line described by each equation means in the context of the coasters.
2) EZ Sales also sells plain natural sandstone coasters for $4.00 each.
a) Write the equation describing this relationship.
b) Indicate whether or not it is a proportional relationship and explain why?
c) Will the graph of this equation ever intersect the graph of the equations for either of the other two EZ Coasters? Explain in typing how you made your decision.

Write equation could use to find number of centimeters in 1 inch.
Answer:
0.393701 cm = 1 in
Step-by-step explanation:
We want to find the number of centimeters in 1 inch.
First, the two conversion rates we need to use:
1m = 100 cm
1m = 39.3701 in
From these two equations, we can conclude that:
100cm = 1m = 39.3701 in
100cm = 39.3701 in
Because we want to find the total number of centimeters in 1 inch, we need to divide both sides by 39.3701
We will get:
(100cm)/39.3701 = (39.3701 in)/39.3701
0.393701 cm = 1 in
This equation gives us the number of centimeters in one inch.

Step-by-step explanation:
A.
Given f(x)=10-2x, find f(7)
Answer:
-4
Step-by-step explanation:
f(x) = 10 - 2x
substitute 7 in place of x
f(7) = 10 -2*7
=10 - 14
=-4
therefore the value of f(7) is -4.
