Answers

Answer:

Step-by-step explanation:

Graph given in the attachment represents a linear function f(x).

y = -f(x) represents the reflection of the graph across x-axis.

Therefore, y-coordinates of the points on the graph will get opposite notation after the reflection across x-axis.

Points on the graph of function f(x) are,

(0, -2), (2, 0), (4, 2) and (5, 1)

Therefore, points for the graph y = -f(x) will be,

(0, 2), (2, 0), (4, -2) and (5, -1)

Now we can plot these points to get the graph of y = -f(x)

Which expression represents the same relationships shown on the graph? y = x - 6 y = x + 6 y = 6x y= - 6x

111 is 15% of what number

Answers

Answer:

16.65

Step-by-step explanation:

15 percent of 111 is the same as 15 per hundred of 111. We can therefore make the following equation:

15/100 = X/111

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 111, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

15/100 = X/111

X/111 = 15/100

X*111/111 = 15*111/100

X = 1665/100

X = 16.65

or

The work above shows the long way to explain how to calculate 15 percent of 111 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:

(Y * P)/100

In our problem "What is 15 percent of 111?", Y is 111 and P is 15:

(111 * 15)/100 = 16.65

And once again you see that the answer is 16.65.

Answer:

740

Step-by-step explanation:

If we substitute "what number" in the question "111 is 15 percent of what number?" with 740, we get this sentence: 111 is 15 percent of 740. Since this statement is true, we know that our answer is correct.

Following shows the steps on how to derive this formula

Step 1: If 15% of a number is 111, then what is 100% of that number? Setup the equation.

111          Y

------  =   -------

15         100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

15Y = 111 x 100

15Y = 11100

Y = 11100

100 = 740

Formula = Number x 100     111 x 100

                 --------------------- = ------------  = 740

                   Percent              15

Answers

Answer:

-6 and -1

Step-by-step explanation:

let's suppose there are two numbers x and y so that it that works that would give the following equations

[tex]x*y=6 \\ x+y =-7[/tex]

now let'S rewrite the first to the form y =

[tex]y=\frac{6}{x}[/tex]

and plug that into the second one

[tex]x+\frac{x}{6} = -7|*6\\6x+x=-42\\7x=-42|:7\\x=-6[/tex]

use that to find out what y is

you can check that with the first equation

Suppose you have just poured a cup of freshly brewed coffee with temperature 90∘C in a room where the temperature is 20∘C.
Newton's Law of Cooling states that the rate of cooling of an object is proportional to the temperature difference between the object and its surroundings. Therefore, the temperature of the coffee, T(t), satisfies the differential equation

dT/dt=k(T−Troom)

where Troom=20 is the room temperature, and k is some constant.
Suppose it is known that the coffee cools at a rate of 1∘C per minute when its temperature is 70∘C.

A. What is the limiting value of the temperature of the coffee?
limt→[infinity]T(t)= ________
B. What is the limiting value of the rate of cooling?
limt→[infinity]dT/dt= _________
C. Find the constant k in the differential equation.
k= _________
D. Use Euler's method with step size h=2 minutes to estimate the temperature of the coffee after 10 minutes.
T(10)= _________

Answers

Solution :

A). As the time passes the temperature of the coffee tends to acquire the temperature of the room, so the limiting value of the temperature of the coffee is 20°C. i.e.

[tex]$\lim_{t \to \infty} T(t)=20$[/tex]

B). And limiting value of rate of cooling is given by :

[tex]$\lim_{t \to \infty} \ \frac{dT}{dt} =\lim_{t \to \infty} \ [k(T-T_{room})] $[/tex]

              [tex]$=k . \lim_{t \to \infty} (T-T_{room})$[/tex]

              [tex]$=k .[ \lim_{t \to \infty} T-\lim_{t \to \infty} T_{room}]$[/tex]

              [tex]$=k.[T_{room}-T_{room}]$[/tex]

              = k. 0

             = 0

C). Given, [tex]$\frac{dT}{dt} = -1, $[/tex] when T(t) = 70° using this in the given equation,

         -1 = k.(70-20)

         k = -0.02

D). By Euler method, we get

      [tex]$T_{n+1}=T_n + h \ f(t_n, T_n)$[/tex]

      [tex]$t_{n+1}=t_n +h$[/tex]

where, [tex]$f(t,T) =k(T-T_{room})$[/tex]

                       = -0.02(T - 20)

We have [tex]$T_0 = 90^\circ$[/tex]  at t = 0 and h = 2.

So [tex]$t_1 = 0+2 = 2$[/tex]

∴ [tex]$T_1=T_0 + h \ f(t_0,T_0)$[/tex]

       = 90+2[-0.02(90-20)]

       = 87.2

At [tex]$t_2 = 2+2 = 4$[/tex]

[tex]$T_2=T_1 + h \ f(t_1,T_1)$[/tex]

   = 87.2+2[-0.02(87.2-20)]

  = 84.51

At [tex]$t_3 = t_2+2 = 4+2=6$[/tex]

[tex]$T_3=T_2 + h \ f(t_2,T_2)$[/tex]

   = 84.51+2[-0.02(84.51-20)]

  = 81.93

At [tex]$t_4 = t_3+4 = 6+2=8$[/tex]

[tex]$T_4=T_3 + h \ f(t_4,T_4)$[/tex]

   = 81.93+2[-0.02(81.93-20)]

  = 79.45

At [tex]$t_5 = t_4+2 = 8+2=10$[/tex]

[tex]$T_5=T_4 + h \ f(t_4,T_4)$[/tex]

   = 79.45+2[-0.02(79.45-20)]

  = 77.07

So after 10 minutes, the temperature of the coffee will be 77.07°C.

write a equation in the form y= mx or y= mx + b to represent the relationship between the independent and dependent qualities?

Answers

Answer:

y = 10x

Step-by-step explanation:

Independent variable (x) = time (minutes)

Dependent variable (y) = distance (feet)

The line passes through the point of origin (0, 0), which means it represents a proportional relationship. Therefore, the equation would be in the form of y = mx. Where,

m = slope = y/x

Using any point on the line, say (5, 50),

m = 50/5

m = 10

To write the equation, substitute m = 10 into y = mx

Thus:

y = 10x

Give a practical interpretation of the estimate of the y-intercept of the regression line. For each additional room in the house, we estimate the appraised value to increase $74,800.

Using the Pythagorean theorem:

Length of wire = sqrt(34^2 + 8^2)

Length of wire = sqrt(1156 +64)

Length of wire = sqrt(1220)

Length of wire = 34.9285 feet

There are 2 wires:

34.9285 x 2 = 69.857 feet

Round off as needed.

Answer:

34.93 feet

Step-by-step explanation:

Using a^2+b^2=c^2

we can substitute a and b in which is

34^2+8^2=c^2

1156+64=c^2

1220 = c^2

The average age at which adolescent girls reach their adult height is 16 years. Suppose you have a sample of 27 adolescent girls who are developmentally delayed, and who have an average age at which they reached their adult height of 17.1 years and a sample variance of 36.0 years. You want to test the hypothesis that adolescent girls who are developmentally delayed have a different age at which they reached their adult height than all adolescent girls.

Calculate the t statistic. To do this, you first need to calculate the estimated standard error. The estimated standard error is SM=_________ .The t statistic is _________. Now suppose you have a larger sample size n 81. Calculate the estimated standard error and the t statistic for this sample with the same sample average and the same standard deviation as above, but with the larger sample size. The new estimated standard error is __________ .The new t statistic is___________

Answers

Answer:

a) t-statistic  t = 0.9532

b) The standard error  S.E = 1.2

c) The new  t-statistic = 1.95

d)  The new estimated standard error =0.666

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 16

The sample size n=27

The mean of the sample = 17.1

Given that the variance of the sample (S²) = 36.0

The standard deviation of the sample (S) = √36 = 6

Test statistic

  [tex]t = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }[/tex]

 [tex]t = \frac{17.1 -16}{\frac{6}{\sqrt{27} } }[/tex]

t = 0.9532

b)

   The standard error is defined by

  [tex]S.E = \frac{S.D}{\sqrt{n} } = \frac{6}{\sqrt{27} } =1.154[/tex]

Step(ii):-  

c) given that the sample size n = 81

Test statistic

 [tex]t = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }[/tex]

 [tex]t = \frac{17.1 -16}{\frac{6}{\sqrt{81} } }[/tex]

t = 1.65

d)

The new standard error is defined by

  [tex]S.E = \frac{S.D}{\sqrt{n} } = \frac{6}{\sqrt{81} } = 0.66[/tex]
