George claims that he is 3 years less than 3 times as old as his niece Pam will be one year from now. Let p= Pam’s age now. Write an expression to represent George's age. Then simplify the expression. If George is 42 years old now, how old will Pam be next year?
Answer:
G = George's age
G = 3(P+1) - 3
G = 3P + 3 - 3
G = 3P

Answer:
106.6 mi/h, 26.6 mi/h
Step-by-step explanation:
PRIMERO SE CALCULA LE VELOCIDAD CON EL VIENTO QUIETO
v = [tex]\frac{320 mi}{3 h}[/tex] = 106.6 mi/h
DESPUÉS SE ENCUENTRA LA VELOCIDAD DEL AVIÓN EN CONTRA DEL
VIENTO
v = [tex]\frac{320 mi}{4 h}[/tex] = 80 mi/h
FINALMENTE SE ENCUENTRA LA VELOCIDAD DEL VIENTO
v = 106.6 mi/g - 80 mi/h = 26.6 mi/h

Step-by-step explanation:
A line passes through the points (4,17) and (7,20). Write a linear function rule in terms of x and y
for this line.
The linear function rule is y=?
Answer:
The linear function rule is [tex]\mathbf{y=x+13}[/tex]
Step-by-step explanation:
A line passes through the points (4,17) and (7,20). Write a linear function rule in terms of x and y
for this line.
The function rule is of form: y=mx+b
Where m is slope and b is y-intercept
Finding slope using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=4, y_1=17, x_2=7, y_2=20[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{20-17}{7-4}\\Slope=\frac{3}{3}\\Slope=1[/tex]
Finding y-intercept b
Using the point (4,17) to find y-intercept b
[tex]y=mx+b\\17=1(4)+b\\17=4+b\\b=17-4\\b=13[/tex]
So, the linear function rule is:
[tex]y=mx+b\\y=1x+13\\\mathbf{y=x+13}[/tex]
The linear function rule is [tex]\mathbf{y=x+13}[/tex]
A line passes through the points (4,17) and (7,20).
The linear function rule is y= 1x+13
Given :
A line passes through the points (4,17) and (7,20).
The linear function is y=mx+b where m is the slope
lets find out slope using formula
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\(4,17) and (7,20)\\m=\frac{20-17}{7-4}=1 \\[/tex]
Slope of the line using the given points is 1
Lets pick any one point (4,17) and use slope to find function rule y
y=mx+b
x is 4 and y is 17 and m=1
[tex]17=1(4)+b\\17=4+b\\17-4=b\\13=b[/tex]
Replace the value of 'b' and write the equation
[tex]y=mx+b\\y=1x+13[/tex]
The linear function rule is y= 1x+13

Answer:
D: 12
Step-by-step explanation:
The entire segment KI is composed of the segments KJ and JI. So:
[tex]KI=KJ+JI[/tex]
We know that KI is 15.
KJ is (2x-15) and JI is (2x-6). Substitute:
[tex]15=(2x-15)+(2x-6)[/tex]
Solve for x. Combine like terms:
[tex]15=4x-21[/tex]
Add 21 to both sides:
[tex]4x=36[/tex]
Hence, the value of x is:
[tex]x=9[/tex]
We know that JI is 2x-6.
We will substitute 9 for x to find JI. So:
[tex]JI=2(9)-6=18-6=12[/tex]
Hence, our answer is D.

Micro Knowledge sells 5 times as many computers as Morse Electronics. The difference in sales between the two stores is 20 computers. How many computers did each store sell?
Answer:
Morse electronics sells 5 computers
Micro knowledge sells 25 computers
Step-by-step explanation:
The computation is shown below:
Let us assume the morse electronics computer be x
So the micro knowledge computers be 5x
And, the difference between them is 20
Now the equation is
5 x - x = 20
4x = 20
x = 5
Hence, the morse electronics sells 5 computers
While on the other hand the micro knowledge sells
= 5 × 5
= 25 computers

A snail can crawl at a rate of 6 cm in 0.75 minutes. Which represents the constant rate of change of the snail's crawl?
Answer:
0.00133m/sStep-by-step explanation:
Given
distance crawled by the snail = 6cm = 0.06m
Time taken = 0.75minutes = 0.75*60
Time taken = 45secs
Required
constant rate of change of the snail's crawl (speed)
Speed of the snail = distance/time;
Speed of the snail = 0.06/45
Speed of the snail = 0.00133m/s
Hence the constant rate of change of the snail's crawl in m/s is 0.00133m/s
A stock price is $100. Volatility is estimated to be 20% per year. What is the an estimate of the standard deviation of the change in the stock price in one week?
Answer: if I’m correct the answer is $0.38
Step-by-step explanation:
The estimate of the standard deviation of the change in the stock price in one week is $2.77.
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
We have:
Stock price = $100
Volatility = 20% ⇒ 0.20
We know the standard deviation of change in the stock price is given by:
[tex]\rm = \frac{stock \ price \times implied \ volatility \times \sqrt{days \ to \ change} }{\sqrt{365} }[/tex]
[tex]\rm = \frac{100\times 0.20\times\sqrt{7} }{\sqrt{365} }[/tex] (1 week = 7 days)
= 5.2343×0.20×2.646
= 2.7699 ≈ $2.77
Thus, the estimate of the standard deviation of the change in the stock price in one week is $2.77.

A teacher keeps track of the number of students that participate at least three times in an optional study session each year. He models the attendance over the last nine years with this function. n(t) = 3.53t^2 - 33.04t + 117.56 Which graph would most likely be associated with the given model?
Answer:
its B
Step-by-step explanation:
The graph that would most likely be associated with the given model is an option(b).
What is a graph?A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
The regression equation is:
n(t) = 3.53t^2 - 33.04t + 117.56
The above regression equation is a quadratic function and non-linear.
thus, the graph must represent a non-linear relationship.
From the graphs, the only graph of the option (b) represents a quadratic function.
Other given options are either linear models or exponential.
Hence, the graph that would most likely be associated with the given model is an option(b).

What is the rat pop in 1990?
What does the model predict the rat pop was in the year 2005?
Answer:
Pop in 1990 = 81 million rats
Pop in 2005 = 127 million rats
Step-by-step explanation:
Given the function, the population of rats in 1990 is when we replace t with "0" which strictly gives the coefficient 81 that represents 81 million rats.
The rat population in 2005 is given by the formula when t = 15
This is: approximately 127 million rats.
