Answer:
The answer would be 5
Step-by-step explanation:
2x2x2=8
Lets use the other 5 since it is already given to us.
so 8x5=40
no we must get 200 with the 40
so 200/40=5
Thus the missing number will be 5

The "cold start ignition time" of an automobile engine is being investigated by a gasoline manufacturer. The following times (in seconds) were obtained for a test vehicle: 1.75, 1.92, 2.62, 2.35, 3.09, 3.15, 2.53, and 1.91. (a) Calculate the sample mean and sample standard deviation. (b) Construct a box plot of the data.
Answers
Answer:
(a) The sample mean and sample standard deviation are 2.415 and 0.5342 respectively.
(b) Shown below.
Step-by-step explanation:
The data set provided is:
S = {1.75, 1.92, 2.62, 2.35, 3.09, 3.15, 2.53, and 1.91}
(a)
Compute the sample mean and sample standard deviation as follows:
[tex]\bar x=\frac{1}{n}\sum\limits_{i}{x_{i}} =\frac{1}{8}\times 19.32=2.415\\\\\\s=\sqrt{\frac{1}{n-1}\sum\limits_{i}{(x_{i}-\bar x^{2})^{2}}}=\sqrt{\frac{1}{8-1}\times 1.9976}=0.5342[/tex]
Thus, the sample mean and sample standard deviation are 2.415 and 0.5342 respectively.

Required:
Rate of change
SOLUTION:
Rate of change for the function is given as [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex].
Let,
[tex] (-3, 3.6) = (x_1, y_1) [/tex]
[tex] (5, 2) = (x_2, y_2) [/tex]
Rate of change = [tex] \frac{2 - 3.6}{5 - (-3)} [/tex]
[tex] = \frac{-1.6}{8} [/tex]
[tex] = -0.2 [/tex]
The rate of change of y with respect to x for this function is -0.2
Given :
The graph of a linear function is shown on the grid
To find the rate of change of y with respect to x , we need to pick two points from the graph
Two points are (-3,3.6) and (5,2)
Lets apply slope formula to find out rate of change
[tex]slope =\frac{y_2-y_1}{x_2-x_1}\\slope =\frac{2-3.6}{5+3} \\slope = -0.2[/tex]
The rate of change of y with respect to x for this function is -0.2

a. 40 inches by 10 inches
b. 10 inches by 2.5 inches
c. 9 inches by 3 inches
d. 7 inches by 3 inches
e. 6.4 inches by 1.6 inches
Answers
Answer:
a. 40 inches by 10 inchesStep-by-step explanation:
Given the measurement of Rectagle A = 8in by 2in. If rectangle B is a scaled copy, this means the length and with of the new triangle by be that of A multiplies by a constant factor.
If the scale is 5:1, this means that the dimension of Rectangle B is as shown;
Length of B = 5(8in) = 40in
Width of new Rectangle B = 2(5) = 10in
Hence the measurement pairs that could be the dimensions of Rectangle B are 40in by 10in
the rest of the measurement are not multiplied by a constant value.

Latoya has a bookcaes with k shelves. There are 14 books on each shelf. Using k, write an expression for the total number of books
Answers
Answer:
Step-by-step explanation:
Pamela has 15 different books. In how many ways can she place her books on two selves so that there is at least one book on each shelf? (Consider the books in each arrangement to be stacked one next to the other, with the first book on each shelf at the left of the shelf.)
Initially, I thought that this would be fairly straight forward. There are two cases where either shelf could be empty and so we would subtract 2 from the total number of permutations which is obviously 15!. It is obvious now that both of these statements are false.
My previous thoughts didn't take into account the fact that there are two shelves and that the books could be stacked in such a way that 5 are on the top shelf and 10 are on the bottom, or 8 on top with 7 on bottom, or any number of other ways. I believe there are 214 ways the books can be distributed amongst the two shelves (keep in mind that each shelf has to have at least one book, 15−1=14) if the ordering of the books didn't matter, but it does. Is this correct?

A population of a particular yeast cell develops with a constant relative growth rate of 0.4225 per hour. The initial population consists of 3.9 million cells. Find the population size (in millions of cells) after 3 hours. (Round your answer to one decimal place.)
Answers
Answer: The population after 3 hours is 13.9 mill.
Step-by-step explanation:
When we have an exponential with:
A = initial population.
r = constant relative growth rate:
t = time.
The function that models this is:
P(t) = A*e^(k*t)
In this case we know that:
A = 3.9 mill.
r = 0.4225 1.
Then the function that models the population of this yeast cell is:
P(t) = (3.9 mill)*e^(0.4225*t)
where t represents the time in hours.
Then if we want to know the population after 3 hours, we should replace t by 3.
P(3) = (3.9 mill)*e^(0.4225*3) = 13.85 mill.
And we want to round our answer to one decimal place, then we must look at the second decimal place, we can see that is a 5, so we should round up.
The population after 3 hours is 13.9 mill.
The exponential function is often used to model the growth or decay of a population
The population size of the yeast cell after 3 hours is 7.9 million
The given parameters are:
[tex]\mathbf{a = 3.9m}[/tex] --- initial number of cells
[tex]\mathbf{r = 0.4225/hr}[/tex] --- rate
The nth term of an exponential function is:
[tex]\mathbf{f(n) = a(1 + r)^{n-1}}[/tex]
After 3 hours; n = 3
So, we have:
[tex]\mathbf{f(3) = a(1 + r)^{3-1}}[/tex]
Substitute values for a and r
[tex]\mathbf{f(3) = 3.9(1 + 0.4225)^{3-1}}[/tex]
[tex]\mathbf{f(3) = 3.9(1 + 0.4225)^{2}}[/tex]
[tex]\mathbf{f(3) = 3.9 \times (1.4225)^{2}}[/tex]
[tex]\mathbf{f(3) = 7.9}[/tex]
Hence, the population size of the yeast cell after 3 hours is 7.9 million

2. During typhoon Ambo, PAGASA tracks the amount of accumulating rainfall. For the first three hours of typhoon, the rain fell at a constant rate of 25mm per hour The typhoon slows down for an hour and started again at a constant rate of 20 mm per hour for the next two hours. Write a piecewise function that models the amount of rainfall as function of time.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following information:
First three hours of typhoon: rate of Rainfall. = 25mm per hour
Typhoon slows down for an hour : then Rainfall began again at a constant rate of 20 mm per hour for the next 2 hours
Piecewise function which models Rainfall ad a function of time
Amount of Rainfall as a function of time = f(t)
f(t) = 25t ; if t≤ 3
When typhoon slowed down for an hour :
f(t) = 0;
f(t) = 25*3 ; for t ∈ (3, 4)
Then Rainfall at a constant rate of 20mm for another 2 hours
f(t) = (25 *3) + 20(t - 4) ; for t ∈ (5, 6)
What is the equation of the line that passes through the point (5,-7) and has a slope of negative 1
Answers
Answer:
y = -x - 2
Step-by-step explanation:
Use equation: y = mx + b, where "m" is the slope and "b" is the y intercept. You are given a slope of -1 for the m. This is usually expressed as just a "-", as the 1 is inferred.
Since you are given a point, plug the x and y values in to the equation.
-7 = -(5) + b
Solve for b:
-7 = -5 + b
-2 = b
Knowing "m" and "b", plug these in to get your final equation
y = -x - 2
Jefferson Middle School needs to see a 300% gain in PTO fundraiser
sales from last year. If they sold a total of $2,420 last year, how much do
they need to sell this year to meet their goal? *
Answers
Given parameters:
Percentage gain = 300%
Selling cost last year = $2420
Unknown:
Selling cost this year = ?
Solution:
To solve this problem;
Profit percent = [tex]\frac{Selling cost this year - Selling cost last year}{Selling cost last year} x 100[/tex]
300 = [tex]\frac{S - 2420}{2420} x 100[/tex]
3 = [tex]\frac{S - 2420}{2420}[/tex]
S- 2420 = 7260
S = $9680
To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.
