Answer:
Answer is A
(100*-m)+(45*n)
Step-by-step explanation: because stock a decreases per sock so your going to multiply 100 times -m because it is decreasing so it will be negative
Then it will be 45*n because it increase per number of stocks so you multiply 45 which is the number of stocks times n

Answer:
293 miles
Step-by-step explanation:
284.58-17.95=266.63
266.63/0.91=293

A statistician believes that the percent population growth rate of major cities has decreased compared to the last decade. To test his claim, he randomly selects major cities and compares the percent population growth between the years 2007 and 2017 to the percent population growth between the years 1997 and 2007. Suppose that data were collected for a random sample of 17 cities, where each difference is calculated by subtracting the percent growth rate from 1997 to 2007 from the percent growth rate from 2007 to 2017. Assume that the percentages are normally distributed. The statistician uses the alternative hypothesis Ha:μd<0. Using a test statistic of t≈−5.053, which has 16 degrees of freedom, determine the range that contains the p-value.
Answer:
The range consisting of the p-value is, 0.000001 < p-value < 0.00001.
Step-by-step explanation:
The dependent t-test (also known as the paired t-test or paired samples t-test) compares the two means associated groups to conclude if there is a statistically significant difference amid these two means.
In this case a paired t-test is used to determine whether the percent population growth rate of major cities has decreased compared to the last decade.
The alternative hypothesis is Hₐ: [tex]\mu_{d}<0[/tex].
The test statistic value is, t = -5.053.
The degrees of freedom is, 16.
Compute the p-value as follows:
[tex]p-value=P(t_{16}<-5.053)=0.000059[/tex]
Thus, the range consisting of the p-value is, 0.000001 < p-value < 0.00001.

Help me solve this PLS
Answer:
Ok so what you have to do to is basically apply Pythagoras Theorem
Step-by-step explanation:
The hypotenuse squared is equal to the sum of the squares of the legs of a right-angle triangle.
[tex]c^2 = a^2 + b ^2[/tex]
Assuming:
c = 10 [tex]\rightarrow[/tex] hypotenuse
a = 6.84 [tex]\rightarrow[/tex] adjacent leg (base of the triangle)
b = ? [tex]\rightarrow[/tex] opposite leg (height of triangle)
[tex]10^2 = 6.84^2 + b^2[/tex]
[tex]b^2 = 10^2 - 6.84^2[/tex]
[tex]b = \sqrt{(10)^2-(6.84)^2}[/tex]
[tex]b = 7.295[/tex]
With that, you can calculate the area of the triangle:
[tex]A_{triangle} = \frac{a*b}{2}[/tex]
[tex]A_{triangle} = \frac{6.84*7.295}{2}[/tex]
[tex]A_{triangle} = 24.95[/tex]
And as your polygon has 9 sides, you can assume that you have 9 of this triangles, so the total area would be:
[tex]A = 9*24.95[/tex]
[tex]A = 224.55[/tex]
And rounding this result to the nearest hundreth:
[tex]A = 220[/tex]

Math workshops and final exams: The college tutoring center staff are considering whether the center should increase the number of math workshops they offer to help students improve their performance in math classes. Faculty would like to know if requiring student attendance at these math workshops will improve overall passing rates for their students in their math classes. They plan to use the number of workshops attended to predict the final exam score and regression analysis to determine the effectiveness of the mandatory workshop attendance policy. Which is the response variable
Answer:
Final Exam score is the response variable.
Step-by-step explanation:
The response variable is the variable of interest. It is what is being tested for given the predictor variables. The response variable is also called the dependent variable and from our question we want to predict final exam scores would improve if attendance is made mandatory or as the question says, required. The number of times attended is the independent variable while final exam score is the response variable.

There is a bag filled with 5 blue and 6 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting exactly 1 blue?

1.) -12-12mi
2.)-6-6mi
3.)12-12mi
4.)6-6mi
Answer:
Step-by-step explanation:
I am assuming that i = √(-1)
3i*2i*(m + i)
= 6i^2(m + i)
= -6(m+ i)
= -6m - 6i.

Calculus 3.10 Linearization (a) y=x^2sin2x (b) y=ln sqrt(1+t^2) find the differential of each.
Answer:
Below in bold.
Step-by-step explanation:
(a) y=x^2sin2x
Using the Product Rule:
dy/dx = x^2*2cos2x + 2xsin2x
dy/dx = 2x(xcos2x + sin2x).
(b) y=ln sqrt(1+t^2)
y = ln (1 + t^2)^1/2
Using the chain rule:
dy/dx = 1 / (1 + t^2)^1/2 * 1/2(1 + t^2)^-1/2 * 2t
= 2t/(1 + t^2)^1/2 * 1/ (2(1 + t^2)^1/2
= 2t / 2(1 + t^2)
= t / ( 1 + t^2).
a car travels at a speed of 85 mph how far will it travel in 15 minutes
Answer:
106.25 mph
Step-by-step explanation:
since the car travels at 85 miles per hour we divide it by 60 seconds in order to find how many miles is it to get in a minute
=> 85mph ÷ 60
divide 85 by 60
=> 1.416
multiply 1.416 by 15 to get how many miles it to go in 15 minutes
=> 21.25
then add it to 85
=> 106.25

Ok, so Jay has a goal of saving money to buy a handheld game console. Jay has reached 10% of his goal and saved $12. Please explain
Answer:
$120
Step-by-step explanation:
10% = 1/10
If Jay has only saved 1/10 of his goal, then to find how much the goal is we multiply how much he has by 10. This will convert 1/10 to 1.
12 x 10 = 120
Jay's goal is $120
