Answer: mean = 8.33, variance =61.11 , standrad deviation = 7.82
Step-by-step explanation:
For geometric distribution,
Mean = [tex]\dfrac1p[/tex]
variance = [tex]\dfrac{1-p}{p^2}[/tex]
Standard deviation[tex]=\sqrt{Variance}[/tex] , where p = probability of success in each trial.
Given: p= 0.12
Mean = [tex]\dfrac1{0.12}=8.33[/tex]
Variance = [tex]\dfrac{1-0.12}{0.12^2}=\dfrac{0.88}{0.0144}=61.11[/tex]
Standard deviation = [tex]\sqrt{61.11}\approx7.82[/tex]
Hence, mean = 8.33, variance =61.11 , standrad deviation = 7.82

inches long
Answer: A. Side a is 26 inches long, side b is 20 inches long, and side c is 10.
Step-by-step explanation:
Scale factor for drawing = 2:1
Dimensions of drawing : 10 in, 5 in, 13 in
Dimension of object = Scale factor x Dimension of drawing
Sides of object:
2 x 10 in =20 in [b]
2 x 5 in = 10 in [c]
2 x 13 in = 26 in. [a]
Hence, the correct option is
A. Side a is 26 inches long, side b is 20 inches long, and side c is 10.
Answer:
Side a is 2.5 inches long, side b is 5 inches long and side c is 6.5 inches long.

At the market, Meyer buys a bunch of bananas for $0.50 per pound and a frozen pizza for $6. The total for his purchase was $8.50.
Which equation can be used to determine how many pounds p of bananas Meyer bought?
A) 0.5p - 6 = 8.50
OB) 0.5p + 6 = 8.50
O C) 6p - 0.5 = 8.50
OD) 6p + 0.5 = 8.50
Answer:
B) 0.5p + 6 = 8.50
Step-by-step explanation:
If bananas cost $0.50 per pound, you would have to multiply that by how many pounds Meyer bought, or p. When you found how many bananas Meyer bought, you would have to add the money for the frozen pizza ($6) That will give you a total of $8.50.
Answer:
5 pounds
Step-by-step explanation:
First, we need to find the value of 0.5p so our equation is:
8.5 - 6 = 2.5
Then we need to find the value of p in that 2.5, so our equation is:
2.5 ÷ 0.5 = 5
So Meyer bought 5 pounds of bananas

A manufacturing firm tests job applicants. Test scores are normally distributed with a mean of 500 and a standard deviation of 50. What is the probability that the candidate score is 600 or greater
Answer:
The probability that the candidate score is 600 or greater
P(X≥ 600 ) = 0.0228
Step-by-step explanation:
Step(i):-
Given mean of the Population = 500
Given standard deviation of the Population = 50
Let 'X' be the random variable in normal distribution
Given X = 600
[tex]Z = \frac{x-mean}{S.D} = \frac{600-500}{50} = \frac{100}{50} =2[/tex]
Step(ii):-
The probability that the candidate score is 600 or greater
P(X≥ 600 ) = P(z≥2)
= 0.5 - A(2)
= 0.5 -0.4772
= 0.0228
Final answer:-
The probability that the candidate score is 600 or greater
P(X≥ 600 ) = 0.0228

The graph shows the number of gallons of white paint that were mixed with gallons of yellow paint in various different ratios:
Graph titled Mixing Paint, horizontal axis labeled Yellow Paint in gallons, and vertical axis labeled White Paint in gallons is shown. The horizontal scale is 0 to 24 in increments of 3. The vertical scale is 0 to 168 in increments of 21. The plotted points are 3, 21 and 6, 42 and 9, 63.
The number of gallons of white paint mixed with 1 gallon of yellow paint is ______.
Answer:
the ratio is 1:7
so the answer is 7 gallons of white paint
Step-by-step explanation:
Hope this helps!!
Answer:
7

what is the slope intercept form of the equation of the line?
Answer:
The slope-intercept form of the equation of the line is:
y = 2/3x + 2
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the points
(0, 2)(3, 4)(x₁, y₁) = (0, 2)
(x₂, y₂) = (3, 4)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [4 - 2] / [3 - 0]
= 2 / 3
Thus, the slope of the line = m = 2/3
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 2
Thus, the y-intercept b = 2
now substituting m = 2/3 and b = 2 in the slope-intercept form
y = mx+b
y = 2/3x + 2
Therefore, the slope-intercept form of the equation of the line is:
y = 2/3x + 2

Answer:
16 2/3%
Step-by-step explanation:
rate of return is the profit (1750 - 1500) over the original investment
250/1500 = .1666 or 16 2/3%
Answer: .1666
Step-by-step explanation:
Tim saw that a pair of $200 dollar jeans had been marked down by 20%. He told his friend that if you took the new price of the jeans and increased that value by 20%, the jeans would return to the original price of $200. is he correct or no?
Hey there!
The answer is no, they would not return to the original price of $200.
This is because when you decrease 200 by 20%, you get 160. Then, if you increase 160 by 20%, you get 192. This is because 20% of 200 and 20% of 160 is different.
Hope this helps! Have a great day, and good luck on your assignment!

Find the general solution of
dy/dx + 2y =6
Answer:
ye^(2x) - 3e^(2x) = C or (y - 3)e^(2x) = C
Step-by-step explanation:
dy/dx + 2y = 6
This is a first order linear ODE.
p(x) = 2
Integrating factor: I(x) = e^(∫ 2 dx) = e^(2x)
e^(2x)(dy/dx + 2y) = 6e^(2x)
e^(2x) dy + 2ye^(2x) dx = 6e^(2x) dx
Integrate both sides of the equation.
ye^(2x) = 3e^(2x) + C
Thus, the general solution is ye^(2x) - 3e^(2x) = C or (y - 3)e^(2x) = C.
