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)

Answer:

-36

Step-by-step explanation:

80 + (-36) = 44

The negative in the 36 allows it to be subtracted from 80

Answer:

80 + -36

Step-by-step explanation:

80 - 44 = 36

80 + -36 = 44

Answer:

x(4 + 4) + 16 = -32

Step-by-step explanation:

-6 times 4 is -24 so then you add -24 + -24 and get -48. Then if you add a positive 16 to the -48 you get -32.

Answer:

The answer is "2.2 h"

Step-by-step explanation:

Speed of Train B:

[tex]= \frac{3}{2} \times 70 \ mph \\\\= 105 \ mph[/tex]

Train B is then moving on:

[tex]= \frac{200 \ miles}{ 105 \ mph} \\\\= 1.905 \ h\\[/tex]

Then it takes Train A to the left:

[tex]\to 1.905\ h + 20 \ min \\\\= 1.905 \ h +0.333 \ h \\\\= 2.238 \ h[/tex]

To get train B to the reference point of train A = 2.2 h

(c) What is the probability that the cause of death was due to perinatal problems or collision with a watercraft? What is the probability that it was due to some other cause? (Enter your answers rounded to four decimal places.) P(perinatal or collision) P(other cause) -"

a) P(collision) = Number of deaths caused by collision / Total number of deaths

P(collision) = 81/392

P(collision) = 0.2066

b) P(not collision) = 1 - P(collision)

P(not collision) = 1 - 0.2066

P(not collision) = 0.7934

c) P(perinatal or collision) = (68+81)/392

P(perinatal or collision) = 0.3801

P(other cause) = 1 - 0.3801

P(other cause) = 0.6199.

Answer:

[tex] -0.2 [/tex]

Step-by-step explanation:

Given:

(-3, 3.6);

(5, 2)

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

Step-by-step explanation:

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.

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

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.
