Is the height of these students a function of their wrist circumference?
A(Yes because as wrist circumference increases height also increases
B(Yes because a line can be fit to these data to predict other pairings.
C(No because the height of 151 cm is paired with two wrist circumferences.
D(No because the wrist circumference of 16 cm is paired with two heights.
Answers
Answer:
Option D(No because the wrist circumference of 16 cm is paired with two heights.
Step-by-step explanation:
In the given graph we have set of points representing the wrist circumferences and heights of six students in Alyssa’s classroom.
x axis represents the wrist circumference while y axis represent the height.
Any relation is called a function if for one value of x we have only one value of y. If the graph passes the vertical line test that is if a vertical line drawn touches the graph at only one point then the graph is called a function.In the given graph for x value x=16 there are two y values 162 and 165.So the graph is not a function.
Among all the options Option D(No because the wrist circumference of 16 cm is paired with two heights.) is the right answer.

For questions 1 and two find the volume of the given prism. Round to the nearest tenth if necessary.
Answers
The volume of the rectangular and triangular prisms are 269.3 cubic centimeters and 1756.3 cubic yards respectively
How to calculate the volume of the prism?The formula for calculating the volume of a prism is given as;
V = lwh
l is the length
w is the width
h is the height
1) The volume of the prism is expressed as;
V = 12.1 * 5.3 * 4.2
V = 269.3 cubic centimeters
2) Volume of the triangular based prism = BH
Base area = 1/2(13)(13)sin60
Base area = 84.5(0.8660)
Base area = 73.177 square yard
Height H = 24 yards
Volume of the prism = 24 * 73.177
Volume of the prism = 1756.3 cubic yards
Hence the volume of the rectangular and triangular prisms are 269.3 cubic centimeters and 1756.3 cubic yards respectively

1) Cost = 5x + 60
2) Cost = 11x
Where x is the number of lessons.
Since we want to find the value of x (the number of lessons), we can set both equations equal to each other:
5x + 60 = 11x
Subtract 5x from both sides:
60 = 6x
Divide by 6:
x = 10

Ebony wants to leave an 18% tip for a $19.82 restaurant bill. The tax is 6.25%, which is added to the bill before the tip.
Answers
1. find the tax. we are told it is 6.25% in decimal form this is .0625. We need to multiply that by the total 19.82 to find the tax so
[tex]0.0625 \times 19.82 = 1.24[/tex]
so the tax is $1.24
2. Add the tax to the total
[tex]19.82 + 1.24 = 21.06[/tex]
3. calculate a 18% tip. we can do this in our head numerous ways (moving the decimal place to find 10% taking half of that for 5% and moving the decimal again for 1% multiply by 3 and add) but for space we will simply do the same as we did for tax
[tex]21.06 \times .18 = 3.79[/tex]
so our tip is $3.79
4. add the tip to the total
[tex]21.06 + 3.79 = 24 .85[/tex]
so with tax and tip her total is 24.85 However I have found it very common for people to tip just on the price before tax. if this is the case calculate the 18% based just on the original price and add that value plus the 1.24 tax
Ebony will pay a total of $24.85 for her meal after adding a 6.25% tax to the original price of $19.82 and then calculating an 18% tip on the resulting amount, which includes the tax.
The student, Ebony, needs to calculate the total cost of a restaurant bill which involves adding tax and a tip. The cost of her meal is $19.82, with a 6.25% tax to be added before calculating an 18% tip.
First, determine the sales tax amount by converting the percent to a decimal:
0.0625 × $19.82 = $1.24.
Add the sales tax to the meal's original cost to find the total before tip:
$19.82 + $1.24 = $21.06.
Next, calculate the tip amount by converting 18% to a decimal and multiplying by the post-tax total:
0.18 × $21.06 = $3.79.
To find the final amount Ebony will pay including the tax and tip, add the tip to the post-tax total:
$21.06 + $3.79 = $24.85.
Ebony will pay $24.85 at the restaurant's register, using either cash or a credit card, to cover her $19.82 meal with tax and tip.

C. Shifted upwards by 28 units
The explanation is shown below:
1. The problem gives you the following linear function:
f(x)=ax+b
Where a is the slope and b is the y-intercept
2. When you graph that linear function, you obtain a line.
3. Therefore, if b (y-incercept) increases 28,000; the line will shifted 28 units upwards.
4. As you can see, the correct answer is the option mentioned above.
Addition of $28,000 means, we are adding 28 to the given function. Addition/Subtraction of a number to the function brings only vertical shift not the horizontal shift.
Addition bring upward shift and Subtraction brings downward shift. So, increase of $28,000 will bring an upward shift of 28 units.
So, the correct answer is option C
you spin a spinner the has 8 equal sized sections numbered. one to eight. Find P( 1 or 2 )
Answers
This wasn't really a complete question but i hope i answered it!!
Fell free to ask questions :)
The probability of spinning a 1 or 2 on a spinner with eight equally sized sections can be calculated using the formula for probability, resulting in a probability of 0.25.
Explanation:The question asks to find the probability of spinning a 1 or 2 on a spinner with eight equally sized sections, each numbered from 1 to 8. The problem is a straightforward application of the concept of probability in mathematics, which can be calculated by the formula P(E) = Number of favourable outcomes / Total number of outcomes.
In this case, the number of favourable outcomes (spinning a 1 or 2) is 2, and the total number of outcomes is the total number of sections on the spinner, which is 8. Therefore, the probability P(1 or 2) is computed as 2 / 8 = 0.25.

(0,4) goes right around to the - y axis. It become (0,-4) with the rotation. and (0,3*-4) = (0,-12) with the dilation.
There is no way that these triangles are congruent. I could have said that right at the very beginning. But there is a way that they are similar. The angles between them remain unaltered. You can test that out with (0,4) to (0,0) to (2,0) which is a right angle (labeled CAB). No matter what you have done in these two steps, that right angle remains. Dilation other than a dilation of 1 will not produce congruence.

The larger leg of a right triangle is 3 cm longer than its smaller leg. The hypotenuse is 6 cm longer than the smaller leg. How many centimeters long is the smaller leg?
Answers
To find the length of the smaller leg of the right triangle, we can use the Pythagorean theorem and solve the equation.
Explanation:Let x be the length of the smaller leg of the right triangle. The larger leg is 3 cm longer, so its length is x + 3. The hypotenuse is 6 cm longer, so its length is x + 6.
According to the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides, we have the equation: x^2 + (x + 3)^2 = (x + 6)^2.
Solving this equation will give us the value of x, which is the length of the smaller leg.

A- 8 in.
B- 32 in.
C- 64 in.
D- 256 in.
Answers
To make a tile with four times the area, the side length of the square is doubled. Thus, the perimeter of the larger tile, which is four times the side length, will be 32 inches.
Explanation:The student is asked to determine the perimeter of a larger square tile if the company wishes to increase the area by 4 times, using a smaller square tile with a perimeter of 16 inches as a reference. The side of the smaller square tile can be calculated by taking the perimeter and dividing it by 4, which equals 4 inches. If we want a square with 4 times the area, it means that each side is doubled, therefore the length of the side of the larger square is 2 x 4 = 8 inches. To find the perimeter of the larger square, we multiply the side length by 4 (since a square has four equal sides), i.e., 8 x 4 = 32 inches. Therefore the perimeter of the larger tile will be 32 inches.

Answers
Dimensions of bigger box = 4ft x 4ft x 5ft
or, 48 in x 48 in x 60 in (Because 1 ft = 12 inch)
We know that, volume of a cuboid is:
V = length x breadth x height
Volumeo f big box = 48 x 48 x 60
= 138240 cubic inch.
Edge length of cube shape box = 12 inch
For cube, volume = edge^3
Volume of cube = (12)^3
= 1728 cubic inch
Number of cube shaped box that can fit into big box = Volume of big box / Volume of cube shaped box
= 138240 / 1728
= 80
Hence, correct answer is D-80.
