24. Reconsider the sample observations on stabilized viscosity of asphalt specimens introduced in Exercise 43 in Chapter 1 (2781, 2900, 3013, 2856, and 2888). Suppose that for a particular application, it is required that true average viscosity be 3000. Does this requirement appear to have been satisfied? State and test the appropriate hypotheses.

Step-by-step explanation:
The Law and Order detectives enter a house at 11:30 am and found a man on the floor murdered. They take his body temperature finding to be 91.8 F. The body is taken to the morgue and at 12:30 pm the body temperature is 84.4 F. Using an exponential model for the body temperature, to the nearest minute, what time was he killed. Normal body temperature is 98.6.
Answer:
Time of murder = 10:39 am
Step-by-step explanation:
Let the equation of exponential function representing the final temperature of the body after time 't' is,
f(t) = [tex]a(e)^{nt}[/tex]
Here, a = Initial temperature
n = Constant for the change in temperature
t = Duration
At 11:30 am temperature of the body was 91.8°F.
91.8 = [tex]98.6(e)^{nt}[/tex] --------(1)
Time to reach the body to the morgue = 12:30 pm
Duration to reach = 12:30 p.m. - 11:30 a.m.
= 1 hour
Therefore, equation will be,
84.4 = [tex]91.8(e)^{n\times 1}[/tex]
eⁿ = [tex]\frac{84.4}{91.8}[/tex]
ln(eⁿ) = ln(0.9194)
n = -0.08403
From equation (1),
91.8 = [tex]98.6(e)^{-0.08403t}[/tex]
[tex](e)^{0.08403t}=\frac{98.6}{91.8}[/tex]
[tex]ln[(e)^{0.08403t}]=ln[\frac{98.6}{91.8}][/tex]
0.08403t = 0.07146
t = 0.85 hours
t ≈ 51 minutes
Therefore, murder was done 51 minutes before the detectives arrival.
Time of murder = 11:30 - 00:51
= 10:90 - 00:51
= 10:39 am

Find the slope of the line that passes through the points (11,13) and (7,10).
Answer:
m = 3/4
Step-by-step explanation:
The horizontal change in x is 4 and the vertical change 3. The slope is therefore m = rise / run = 3/4.
Answer:
Slope is equal to the change in y over the change in x , or rise over run.
m=change in / y change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope.
m=10−(13)/7−(11) Simplify.
m=34
Step-by-step explanation:
A study of the career paths of hotel general managers sent questionnaires to an SRS of 160 hotels belonging to major U.S. hotel chains. There were 103 responses. The average time these 103 general managers had spent with their current company was 11.7 years. Give a 99% confidence interval for the mean number of years general managers of major-chain hotels have spent with their current company. (Take it as known that the standard deviation of time with the company for all general managers is 3.6 years.)
Answer:
(10.78483, 12.61517)
Step-by-step explanation:
It is given that the genera mangers of few hotels were sent some questionnaires for conducting a study for the career paths in the major hotel chains of the United States.
Number of hotels = 160
Number of response received = 103
The average number of years these general mangers was in their current hotels, [tex]$\bar x$[/tex] = 11.7 years
Confidence Interval, CI = 0.99
Therefore,
a = 0.01, |Z(0.005)| (from standard normal table)
∴ 99% of CI = [tex]$\bar x \pm Z \times \frac{s}{\sqrt n}$[/tex]
[tex]$= 11.7 \pm 2.58 \times \frac{3.6}{\sqrt {103}}$[/tex]

Help need to find the answer
Answer:
242 ft²
Step-by-step explanation:
The shape can be decomposed to give us a trapezium and a rectangle
Area of the shape = area of the trapezium + area of the rectangle
✔️Area of the trapezium = ½(a + b)h
a = 14 ft
b = 20 ft
h = 13 - 7 = 6 ft
Area = ½(14 + 20)*6
Area of trapezium = 102 ft²
✔️Area of rectangle = L*W
L = 20 ft
W = 7 ft
Area = 20*7 = 140 ft²
✔️Area of the shape = 102 + 140 = 242 ft²

let m represent the number of children playing soccer. those children are separated into four equal groups. write an expression for the number of children on each team. what is the answer to this does anyone know?
Answer:
m/4
Step-by-step explanation:
m is how many children are playing.
They are separated into 4 groups. Making it m(how many people are playing), out of 4.
For example, if m=12, then it would be 12/4, so 3 children will be in each group.

Answer:
5:35

The following formula gives the temperature's measure in degrees Fahrenheit F, where C is the measure
in degrees Celsius:
F=
9
C + 32
5
Rearrange the formula to highlight the measure in degrees Celsius.
Answer:
The rearrenged formula is [tex]C = \frac{5(F - 32)}{9}[/tex]
Step-by-step explanation:
Celsius to Fahrenheit:
To realize the conversion of the temperature in degrees Celsius to degrees Fahrenheit, we use the following equation:
[tex]F = \frac{9C}{5} + 32[/tex]
Rearrange the formula to highlight the measure in degrees Celsius.
We want to find C in function of F. So
[tex]F = \frac{9C}{5} + 32[/tex]
[tex]\frac{9C}{5} = F - 32[/tex]
[tex]C = \frac{5(F - 32)}{9}[/tex]

Fatuma recently hired an electrician to do some necessary work. On the final bill, Fatuma was charged a total of $708. $480 was listed for parts and the rest for labor. If the hourly rate for labor was $57, how many hours of labor was needed to complete the job?
Answer:
4 hours.
Step-by-step explanation:
First we need to subtract $480 from $708.
$708-$480= $228.
Because the hourly rate is $57 we need to divide 228 by 57.
228÷57=4
The answer is 4 hours.

A donut machine can make 3000 donuts in 10 hours. How long would it take the machine to make 600 donuts? How many donuts are made per minute?
Answer:
it would take it 2 hours to make 600 donuts, it makes 5 donuts a minutes
Step-by-step explanation:
Simple math.
3000/10=300 which means 300 donut per hour.
300 x 2 = 600.
300 / 60 = 5.

is x(4x^2+8x+12) completely factored? If not how else can it be factored ?
A. Yes the polynomial is completely factored
B. No 4 can be factored from each term of the trinomial and the resulting trinomial can be factored into two binomials.
C.no 4 can be factored from each term of the trinomial
D. No the trinomial 4x^2+8x+12 can be factored into two binomials
No 4 can be factored from each term of the trinomial. Therefore, option C is the correct answer.
What is factorization?The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.
The given polynomial is x(4x²+8x+12).
Here, in the trinomial 4x²+8x+12, 4 is common factor in each term.
So, group and factor out the greatest common factor (GCF), then combine.
That is, 4(x²+2x+3)
Now, x(4x²+8x+12)= 4x(x²+2x+3)
Therefore, option C is the correct answer.
