Answer:
The missing value y=12.5 and we have (5,12.5)
Step-by-step explanation:
The formula used for direct variation is:
[tex]y\: \alpha \:x\\y=kx[/tex]
We need to find missing value (2,5)(5,y)
First we will find k, and then y
We have x=2, y=5
Find k:
[tex]y=kx\\5=k(2)\\k=\frac{5}{2}\\k=2.5[/tex]
Now, we cam find missing value in (5,y)
We have x=5, k=2.5 and y=?
[tex]y=kx\\y=2.5(5)\\y=12.5[/tex]
So, the missing value y=12.5 and we have (5,12.5)

Based on the pie chart, the four largest locations for soft drink sales
account for approximately what percentage of total soft drink sales in
the year under consideration?
Answer: 95%
Step-by-step explanation:
With the information provided, the four largest merchants are Grocery Stores, Fountain, Gas Stations, and Vending Stores.
These stores each make up 44%, 24%, 16%, and 11%, respectively.
The sum of these percentages is 95%. Thus, the four largest locations for soft drink sales make up 95% of soft drink sales.

Corbin is selling cheese at the farmers’ market. One wheel of cheese has a diameter of 11 inches.
Part A Calculate the area of the wheel of cheese. Use 3.14 for π.
Part B
If the 11-inch wheel of cheese costs $21.35, what is the cost per square inch?
Pls help me, I’m desperate lm.ao
its been so long and no one is answering ??? xD
Answer:
I. 94.99 in²
II. $0.23
Step-by-step explanation:
Given the following data;
Diameter of wheel = 11 inches
[tex] \pi = 3.14[/tex]
Cost of wheel = $21.35
[tex] Radius, r = \frac {diameter}{2} [/tex]
[tex] Radius, r = \frac {11}{2} = 5.5 \; inches [/tex]
Part A
To find the area;
We know that a wheel is circular in nature. Thus, the area of a circle is given by the formula;
[tex] Area, A = \pi r^{2} [/tex]
Substituting into the equation, we have;
[tex] Area, A = 3.14 * 5.5^{2} [/tex]
[tex] Area, A = 3.14*30.25[/tex]
Area, A = 94.99 in²
Part B
To find cost per square inch;
[tex] Cost \; per \; square \; inch = \frac {Cost \; per \; wheel}{Area \; of \; wheel} [/tex]
[tex] Cost \; per \; square \; inch = \frac {21.35}{94.99} [/tex]
Cost per square inch = $0.23

△FGH is translated up 2 units to form the image ∆F′G′H′.
What are the coordinates of the vertices of ∆F′G′H′ ?
Enter your answer by filling in the boxes.
F′ = ( , )
G′ = ( , )
H′ = ( , )
Answer:
I hope the Picture Helps!
Step-by-step explanation:
<333
The required coordinates of the vertices of ∆F′G′H′ is F' = (-5, 2), G'= (0, 2), and H' = (0, 6).
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
As mentioned in the question, a given triangle on coordinate axes translated 2 units up. The term "2 unit up" implies that each ordinate of the coordinates of the triangle is increased by 2 units,
So the trasformation equation for the triangle is given as,
(x, y) ⇒ (x, y+2)
Now, the coordinates of the vertices of ∆FGH,
F = (-5, 0), G= (0, 0) H = (0, 4)
After the trasformation coordinate of ∆F′G′H′
F' = (-5, 0 + 2), G'= (0, 0 + 2) H' = (0, 4 + 2)
F' = (-5, 2), G'= (0, 2) H' = (0, 6)
Thus, the required coordinates of the vertices of ∆F′G′H′ is F' = (-5, 2), G'= (0, 2), and H' = (0, 6).

Find the volume of the solid generated by revolving the region bounded by the graphs of the equations and inequalities about the y-axis.x2 - y2 = 64, x \geq 0, y = -8, y = 8
Answer:
The Volume of the solid
V = π(1365.33) cubic units
Step-by-step explanation:
Step(I):-
Given curves are x²- y² = 64 , x=0 , y=-8 and y=8
The given function x = f(y)
x²- y² = 64
x² = y² +64
The Volume of the solid generating by revolving the region bounded by the graphs of the equations
[tex]V = \pi \int\limits^a_b {x^2} \, dx[/tex]
Step(ii):-
the limits are y = a = -8 and y = b=8
The Volume of the solid
[tex]V =\pi \int\limits^8_8 {(y^2+64)} \, dx[/tex]
[tex]V = \pi (\frac{y^{3} }{3} + 64 y )_{-8} ^{8}[/tex]
[tex]V = \pi (\frac{(8)^{3} }{3} + 64 (8) - (\frac{(-8)^{3} }{3} +64(-8) )[/tex]
[tex]V = \pi (\frac{(8)^{3} }{3} + 64 (8) - (\frac{(-8)^{3} }{3} +64(-8) ) = \pi (\frac{1024}{3} + 1024)[/tex]
V = π(1365.33) cubic units

Answer:
4^5 (the 5 is the exponent)The exponential form of expression is 4⁵.
What is exponential form?To grow at an ever-increasing rate is referred to as exponential growth. On the other hand, it is a mathematical expression with one or more exponents in mathematics. As a result, we call it an exponential form.
We can say that something might grow at an exponential rate if it grows faster and faster as the thing being discussed gets bigger.

A. In 2016, 240 out of 400 statistics students at Oxnard Technical College sold their textbooks at the end of the semester, compared with 220 out of 330 students in 2015, a significant decrease.
B. Our new manufacturing technique has increased the life of the 80 GB USB AsimoDrive external hard disk significantly, from 240,000 hours to 250,000 hours.
C. In 50,000 births, the new vaccine reduced the incidence of infant mortality in Morrovia significantly from 14.2 deaths per 1000 births to 10.3 deaths per 1000 births.
D. The new Sky Penetrator IV business jet's cruising range has increased significantly from 3,975 miles to 4,000 miles.
Answer:
The distinction between statistical significance and practical importance is best illustrated by:
C. In 50,000 births, the new vaccine reduced the incidence of infant mortality in Morrovia significantly from 14.2 deaths per 1000 births to 10.3 deaths per 1000 births.
Step-by-step explanation:
Current state Previous state Change
A. Textbooks sold 240/400 (0.6) 220/330 (0.67) 0.07
B. Life of hard disk 250,000 hrs 240,000 hrs 0.04
C. Infant mortality 10.3 per 1000 14.2 per 1000 0.27
D. Cruising range 4,000 miles 3,975 miles 0.006
Statistical significance, which depends on the p-value established before the test, relates to whether an effect exists, while practical significance determines the magnitude or size of the effect. A statistical test cannot tell whether the magnitude is large enough to be important. Mathematically, the change can be determined, which establishes the practical significance or importance of the change.

Answer:
The ratio of the diameter of ball A to the diameter of ball B is 10:19.
Step-by-step explanation:
Ratios
A ratio is a relation between two quantities and it's calculated as a division. For example, the ratio between 8 and 4 is 8:4 = 8 / 4 = 2.
We are given the diameters of two balls as follows:
The diameter of the ball A=30mm
The diameter of the ball B=5.7 cm = 57 mm
The ratio of the diameter of ball A to the diameter of ball B is 30:57. Dividing both numbers by 3, we have: ratio=10:19
The ratio of the diameter of ball A to the diameter of ball B is 10:19.
