Two numbers are independently selected from the set of positive integers less than or equal to 5. What is the probability that the sum of the two numbers is less than their product? Express your answer as a common fraction.
Answer: P = 15/25
Step-by-step explanation:
The set of numbers that we have here is:
{1, 2, 3, 4, 5}
We select independently two numbers of that set (so the numbers can be repeated.
We want to find the probability where the sum of the numbers is less than the product.
if one of the selected numbers is 1, then always the sum will be larger than the product, because:
1*1 = 1 and 1 + 1 = 2
1*2 = 2 and 1 + 2 = 3.
and so on.
if both numbers are 2, the sum is equal to the product:
2*2 = 4 = 2 + 2.
if else, the product will be larger than the product.
The first step now is to calculate the total number of possible combinations of 2 numbers:
For the first number, we have 5 options.
for the second number, we have 5 options.
The total number of combinations is equal to the product of the number of options in each case:
C = 5*5 = 25
Now, the combinations where the product is LESS OR EQUAL than the sum are:
1 and 1
1 and 2
1 and 3
1 and 4
1 and 5.
2 and 1
3 and 1
4 and 1
5 and 1
2 and 2.
10 combinations.
Then the combinations where the product is larger than the sum is:
25 - 10 = 15.
Then the probability that we are looking for is:
P = 15/25
What are the degrees of freedom associated with the factor(s) in this study design?
Answer:
The question is unclear and incomplete.
Let me explain the degrees of freedom in statistics.
Step-by-step explanation:
Statistically, degrees of freedom which is denoted as DF is the number of independent values that can vary in an analysis without breaking any constraints. It can also be referred to as the number of independent values that a statistical analysis can estimate.
Degrees of freedom also define the probability distributions for the test statistics of various hypothesis tests.
The degree of freedom has the formula:
DF = N - 1 where N number of random variables
DF = (R - 1) x (C - 1) Where R is the number of data values and C is the number of groups

You have a choice between going to an in-state college where you would pay $5500 per year for tuition and an out-of-state college where the tuition is $7000 per year. The cost of Iiving is much higher at the in-state college, where you can expect to pay $1000 per month in rent, compared to $750 per month at the other college Assuming all other factors are equal, which is the less expensive choice on an annual (12-month) basis? The yearly expense of the in-state college is $_____and the yearly expense of the out-of-state college is $______. Thus on an annual basis, the less expensive choice is the (1)_______college. (Simplify your answers.) in-state out-of-state
The yearly expense of the in-state college is $16000.
We are given that;
An out-of-state college where the tuition = $7000 per year.
Now,
The yearly expense of the in-state college is:
=5500+12⋅1000
=5500+12000
=17500
By solving;
The yearly expense of the out-of-state college is:
=7000+12⋅750
=7000+9000
=16000
So, on an annual basis, the less expensive choice is the out-of-state college.
Therefore, by algebra the answer will be 16000.

The 10,000-meter long-distance running event in the summer Olympics is approximately 6.2 miles. Which equation could be used to determine the time, t, it takes to run 10,000 meters as a function of the average speed, s, of the runner where t is in minutes and s in miles per minute?
The equation that could be used to determine the time, t, it takes to run 10,000 meters as a function of the average speed, s, of the runner where t is in minutes and s in miles per minute is t = 6.2/s miles/minute
What is an average speed?Average speed is defined as the rate of change in distance of a body. Mathematically;
Speed = Distance/TimeGiven the distance of the runner in miles to be;
d = 6.2milesTime taken = tAverage speed = sTo express t in terms of the average speed s and distance of 6.2miles, we will substitute the values into the formula;
s = D/tSubstituting D = 6.2miles into the formula;
s = 6.2/tCross multiply
St = 6.2Divide both sides by 's'
st/s = 6.2/s
t = 6.2/s
Hence, the equation that could be used to determine the time, t, it takes to run 10,000 meters as a function of the average speed, s, of the runner where t is in minutes and s in miles per minute is t = 6.2/s miles/minute

when graphing the function f(x)=-|x+5|+12 on your graphing calculator, what is the most appropriate viewing window for determining the domain and range of the function
Answer: is B
Step-by-step explanation:
-20, xmax
The most appropriate viewing window for determining the domain and range of the function is Xmin: –20, Xmax: 20Ymin: –20, Ymax: 20.
The given function is f(x)=-|x+5|+12.
We need to find the most appropriate viewing window for determining the domain and range of the function.
What is the domain and range of the function?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: (-∞, ∞), {x|x∈R}
Range: (-∞, 12], {y|y≤12}
So,window=Xmin: –20, Xmax: 20Ymin: –20, Ymax: 20
Therefore, the most appropriate viewing window for determining the domain and range of the function is Xmin: –20, Xmax: 20Ymin: –20, Ymax: 20.

Number of teachers = 15
Lets take the number of students = x
Therefore,
5:1 = x:15
= 5/1 = x/15
x = 15 × 5

If angle EFH(5x+1)’ angle HFG(62 degrees) and angle EFG (18x+11) find each measurement
Answer:
∠EFH = 21°
∠HFG = 62°
∠EFG = 83°
Step-by-step explanation:
The diagram showing the angles has been attached to this response.
From the diagram, it can be deduced that;
Angle EFG = angle EFH + angle HFG
=> ∠EFG = ∠EFH + ∠HFG -------------------(i)
From the question:
∠EFH = (5x + 1)° -------------(ii)
∠HFG = 62° -------------(iii)
∠EFG = (18x + 11)° -------------(iv)
Substitute these values into equation (i) as follows;
(18x + 11) = (5x + 1) + 62
=> 18x + 11 = 5x + 1 + 62
Collect like terms and solve for x
18x - 5x = 1 + 62 - 11
13x = 52
x = 4
Now, to get each measurement, substitute x = 4 into each of equations (ii) - (iv)
∠EFH = (5x + 1)°
∠EFH = (5(4) + 1)°
∠EFH = (20 + 1)°
∠EFH = 21°
∠HFG = 62° [Does not depend on x]
∠EFG = (18x + 11)°
∠EFG = (18(4) + 11)°
∠EFG = (72 + 11)°
∠EFG = 83°
Conclusion:
∠EFH = 21°
∠HFG = 62°
∠EFG = 83°

Find (a) PQ to the nearest tenth and (b) the coordinates of the midpoint of PQ.
P(2.6), Q(-6,1)
(a) PQ=(Round to the nearest tenth as needed.)
Answer/Step-by-step explanation:
Given:
P(2, 6)
Q(-6, 1)
Required:
a. PQ
b. Coordinate of the midpoint of PQ
SOLUTION:
a. [tex] PQ = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] P(2, 6) = (x_1, y_1) [/tex]
[tex] Q(-6, 1) = (x_2, y_2) [/tex]
[tex] PQ = \sqrt{(-6 - 2)^2 + (1 - 6)^2} [/tex]
[tex] PQ = \sqrt{(-8)^2 + (-5)^2} = \sqrt{64 + 25} [/tex]
[tex] PQ = \sqrt{89} = 3.1 [/tex] (to nearest tenth)
b. Coordinate of the midpoint of PQ
[tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]
Let [tex] P(2, 6) = (x_1, y_1) [/tex]
[tex] Q(-6, 1) = (x_2, y_2) [/tex]
Thus:
[tex] M(\frac{2 +(-6)}{2}, \frac{6 + 1}{2}) [/tex]
[tex] M(\frac{-4}{2}, \frac{7}{2}) [/tex]
[tex] M(-2, \frac{7}{2}) [/tex]
The coordinates of the midpoint of PQ are (-2,3.5) and this can be determined by using the midpoint formula.
Given :
Coordinates -- P(2,6) and Q(-6,1)
The following steps can be used in order to determine the coordinates of the midpoint of PQ:
Step 1 - According, to the given data, the coordinates of point P(2,6) and Q(-6,1).
Step 2 - The formula of midpoint can be used in order to determine the midpoint of PQ.
Step 3 - The midpoint formula is given below:
[tex]\rm x = \dfrac{x_1+x_2}{2}[/tex]
[tex]\rm y = \dfrac{y_1+y_2}{2}[/tex]
Step 4 - Substitute the values of the coordinates in the above formula.
[tex]\rm x = \dfrac{2-6}{2} = -2[/tex]
[tex]\rm y = \dfrac{6+1}{2}=3.5[/tex]

1) A swimming pool currently has 1,500 gallons of water in it and is filling at a rate of two gallons per hour. How many gallons will the pool hold in eight hours?
Answer:
1516 Gallons
Step-by-step explanation:
For this problem, we will simply take the initial amount of water, 1500 gallons, and add the extra water after eight hours.
So if the pool is filling at a rate of 2 gallons per hour, and 8 hours pass by, then the pool will have filled an additional 16 gallons. (2 * 8 = 16).
Then, we add the initial amount of 1500 gallons to the additional 16 gallons to get the amount of water in the pool after 8 hours.
The total the pool is holding is 1516 gallons after 8 hours.
