Answer:
See below
Step-by-step explanation:
Using the two pairs of (a, p) to determine the function:
(45, 18) and (25, 78)The function would be:
f(a) = ma + b, where m is slope, b is p-interceptSlope is:
m = (78 - 18)/(25 - 45) = -50/20 = -2.5p-intercept:
18 = -2.5*45 + bb = 18 + 112.5 = 120.5So the function is:
(a)
f(a) = -2.5a + 120.5(b) Slope is negative, indicating the lower probability at greater age. P-intercept of 120.5 is of the non-real case as for zero age it gives more than 100% probability.
(c) The domain needs restriction in line with law, so minimum age and maximum to be determined in order not to have unrealistic outcome. It should be ok between 18 and 48.
(d) The values at given points:
f(20 = -2.5*20 + 120.5 = 70.5f(30) = -2.5*30 + 120.5 = 45.5f(50) = -2.5*50 + 120.5 = -4.5 (negative probability for the age of 50 is not real)Select the common unit rate you would use to solve a problem involving the speed of a vehicle.

The percentages associated with each unit of standard deviation are all 0, since the standard normal curve is symmetric and the area under the curve for each interval of the same length and equidistant from the mean is equal.
What is standard deviation?A standard deviation is a measure of how far apart the data is from the mean.
The table shows the area under the standard normal curve for different values of x, where x is the number of standard deviations from the mean.
To find the percentage associated with each unit of standard deviation, we can subtract the area from the table for the lower value of x from the area for the higher value of x, and round the result to the nearest hundredth.
For example, the percentage associated with one unit of standard deviation, from -1 to 0 or from 0 to +1, is:
Area from -1 to 0: 0.3413
Area from 0 to +1: 0.3413 (symmetric curve)
Percentage: 0.3413 - 0.3413 = 0 (rounded to nearest hundredth)
The percentage associated with two units of standard deviation, from -2 to 0 or from 0 to +2, is:
Area from -2 to 0: 0.4772
Area from 0 to +2: 0.4772 (symmetric curve)
Percentage: 0.4772 - 0.4772 = 0 (rounded to nearest hundredth)
Similarly, we can find the percentages associated with other units of standard deviation:
From -3 to 0 or from 0 to +3: 0.4987 - 0.4987 = 0
From -4 to 0 or from 0 to +4: 0.4999 - 0.4999 = 0
Therefore, because the standard normal curve is symmetric and the area under the curve for each interval of the same length and equidistant from the mean is equal, the percentages associated with each unit of standard deviation are all zero.

In 2006, 65.2 million people subscribed to cable television. In 2013, that number had decreased to 54.2 million. Find the percent decrease in the number of cable TV subscribers from 2006 to 2013. Round to the nearest tenth of a percent.
Given :
In 2006, 65.2 million people subscribed to cable television.
In 2013, that number had decreased to 54.2 million.
To Find :
The percent decrease in the number of cable TV subscribers from 2006 to 2013.
Solution :
Decrease in the number of cable TV subscribers from 2006 to 2013 is :
[tex]Percetage\ Decrease = \dfrac{Decrease\ in \ price}{Initial\ price}\times 100\\\\Percetage\ Decrease = \dfrac{65.2-54.2}{65.2}\times 100\\\\Percetage\ Decrease = 16.87[/tex]
Therefore, percentage decrease is 16.87 %.
Zach filled 581 one-liter bottles with apple cider. He distributed the bottles to 4 stores. Each store received the same number of bottles. How many liter bottles did each of the stores receive? Were there any bottles left over?
a. 145 liter bottles (There were 2 bottles remaining)
b. 142 liter bottles (There were 2 bottles remaining)
c. 145 liter bottles (There was 1 bottle remaining)
Answer:
a. 145 liter bottles (There were 2 bottles remaining)
Step-by-step explanation:
From this question, the total number of bottles that Zach had to fill with apple cider is 581.
He has to distribute these bottles to 4 stores after filling
The question says each store received same number of bottles.
To get the number of bottles received by each store, we divide 581 by 4
= 581 / 4
= 145.25
Therefore each store gets 145 bottles each and there would be a remainder of 2 bottles

Step-by-step explanation:
There are 12 inches in a foot
So for one full foot in inches you have just 1 foot with 6 inches remaining/ 1 foot with half a foot remaining.
Hope this helped!
Answer: 8 pieces.
Step-by-step explanation;
There is 12 inch in a foot, so they are 144 inches in 12 foot. If India cuts 18-inch pieces, she can cut 8 pieces. You can find this amount by dividing 144 inches into 18 inches, this will be eight pieces.

The temperature outside is currently 10°F. It will fall at a constant rate of 3°F per hour. Which temperature will it be in 4 hours?
A
22°F
B
7°F
С
-2°F
D
-12°F
Answer:
The temperature in 4 hours = -2 °F
Thus, option (D) is true.
Step-by-step explanation:
We know that the slope-intercept form of the line equation is
[tex]y = mx+b[/tex]
where m is the rate of change or slope and b is the y-intercept
Let 'y' be the temperature Let 'x' be the time of the temperature in the hour
Given that the current temperature outside = 10°F.
Thus, the y-intercept = b = 10°F
Given that as the day went on, It will fall at a constant rate of 3°F per hour.
Thus, the slope or rate of change = -3°F
(The rate of change or slope is -3 because the temperature is reducing)
Thus, the rate of change = slope = m = -3
Thus, substituting m = -3 and b = 10 in the equation
[tex]y = mx+b[/tex]
[tex]y = -3x + 10[/tex]
Now, substituting x = 4 to determine the temperature after 4 hours.
y = -3(4) + 10
y = -12 + 12
y = -2 °F
Therefore, the temperature in 4 hours = -2 °F
Thus, option (D) is true.
Scenario: Does the age at which babies learn to crawl depend on the time of the year that the babies were born? Data were collected from parents who brought their babies into the University of Denver’s Infant Study Center to participate in one of a number of experiments between 1988 and 1991. Parents reported the birth month and the age in which their child first began to crawl. The resulting data were grouped by month of birth: January, May, and September.
The age for when babies learn to crawl is different for Januar,May, and September.. so I guess yes?

Suppose y varies directly with x. Write a direct variation equation to relate x and y if y = 10 when x = 2
Answer:
y=5x and y=40 when x=8
Answer:
y = 5x
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 10 when x = 2
10 = 2k ( divide both sides by 2 )
5 = k
y = 5x ← equation of variation
