Answer:

Test statistic   Z = 2.1097

Step-by-step explanation:

Step(i):-

Given that size of the sample 'n' = 160

Given that mean of the Population(μ)  = 5.3pounds/square inch

The Standard deviation of the population(σ) = 0.6

Mean of the sample(x⁻) = 5.4

Level of significance =0.1

Step(ii):-

Test statistic

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

   [tex]Z = \frac{5.4-5.3}{\frac{0.6}{\sqrt{160} } }[/tex]

  Z = 2.1097

Final answer:-

Test statistic   Z = 2.1097

Answer:

Below

Step-by-step explanation:

1. Linear because it is of the form y = mx + b. The variable x  is of the first degree.

The coefficient of x (1/3)  ( = slope) is positive so it is increasing.

2. This is non-linear because the variable x is an exponent.

3. Because  its of the second degree (x^2) - it is non-linear.

Step-by-step explanation:

Answer:

Relevant domain: [0 40]

Relevant range: [0 80]

Step-by-step explanation:

We have the following function:

[tex]C(t) = 80 - 2t[/tex]

In which C(t) is the water temperature.

t is the time.

The colling period ends when the water freezes (0°).

So it freezes after t minutes, and t is found when C(t) = 0. So

[tex]C(t) = 80 - 2t[/tex]

[tex]80 - 2t = 0[/tex]

[tex]2t = 80[/tex]

[tex]t = \frac{80}{2}[/tex]

[tex]t = 40[/tex]

Relevant domain:

Input value of the function, which is in minutes. So between 0(initial) and 40(when the water freezes).

Relevant range:

Initial temperature, which is C(0) = 80, until it freezes, 0. So from 0 to 80.

Answer:

40

Step-by-step explanation:

Set up a ratio.  Solve for x.

3/5 = 24/x

3x = 120

x = 40

Reeta is 40 years old.

Answer:

40

Step-by-step explanation:

For every three years mark has, reeta has five.

Find out how many 'three years' mark has: 24/3 = 8

For every 'three years' he has, reeta has five. 5*8=40

The answer is True

Step-by-step explanation:

False

Answer:

The answer is below

Step-by-step explanation:

1) When you are computing the sums of numbers, you do not round up. You have to be exact.

Summing numbers involves you adding the numbers together as well as their decimals. Therefore:

$5.89 + $1.45 = $7.34

2) When you are computing the product of numbers, you do not round up. You have to be exact.

The product of numbers involves you multiplying the numbers together. Therefore:

$5.89 per pound * 4 pounds of beef = $23.56

Answer:

108 x 25²  divided by 2⁶ x 5² is equal to [tex]42\frac{3}{16}[/tex]

Step-by-step explanation:

Given;

108 x 25²  divided by 2⁶ x 5²

The expression is simplified as follows;

[tex]\frac{108\times 25^2}{2^6 \times 5^2} = \frac{108\times 625}{64\times25} =\frac{675}{16} = 42\frac{3}{16}[/tex]

Therefore, 108 x 25²  divided by 2⁶ x 5² is equal to [tex]42\frac{3}{16}[/tex]

Answer:

Step-by-step explanation:

to find out how much Angela she would have in the bank,

(600*3.6*1)100=21.60 she gains in one year

6 months  21.60/2=10.80

in 4.5 years

(21.60*4)+10.80=86.40+10.80=97.20 interest

the balance=600+97.20=697.20

what is this

Step-by-step explanation:

Option #1 – charges 5% simple interest per year; this is a short-term loan for only 5-years.

Option #2 – charges 7% simple interest per year; this is a short-term loan for only 3-years.

Option #3 – charges 3.2% simple interest per year; there is no time limit on this loan (as a group determine how long you think it will take you to make enough money to be able to pay back the loan with interest)

Option #4 - charges 10% simple interest per year; only lasts 10 months

Option what is this

Answer: The length = [tex]5\dfrac12[/tex] units

Step-by-step explanation:

Given: Area of carpet = [tex]4\dfarc18 \text{ sq. units}=\dfrac{33}{8}\text{ sq. units}[/tex]

Width of carpet = [tex]\dfrac34[/tex] units

Shape of carpet = Rectangle

Area of rectangle = length x width

So,

length = [tex]\dfrac{Area}{width}[/tex]

[tex]=\dfrac{\dfrac{33}{8}}{\dfrac34}\\\\=\dfrac{33}{8}\times\dfrac43\\\\=\dfrac{11}{2}\\\\=5\dfrac12\text{ units}[/tex]

Hence, the length = [tex]5\dfrac12[/tex] units

Answer:

Step-by-step explanation:

Answer:

There are 50 pages in the book.

Step-by-step explanation:

Given that:

Martin has read 40% of the book.

Remaining percent = (100 - 40)% = 60%

Number of pages left to finish = 30

Let,

x be the total number of pages in the book.

60% of x = 30

[tex]\frac{60}{100}x=30[/tex]

0.6x = 30

Dividing both sides by 0.6

[tex]\frac{0.6x}{0.6}=\frac{30}{0.6}\\x= 50[/tex]

Hence,

There are 50 pages in the book.

Answer:

y = x - 3

Step-by-step explanation:

First you want to combine like terms (so get x on one side and y on the other).

2y = 5y + 9 - 3x

-3y = -3x + 9

Then just solve for y by dividing by -3

y = (-3x + 9)/-3

y = x - 3

Answer:

15:x or 15 to x

Step-by-step explanation:

it depends on what the question is asking, so if they want you to fill in a number, you could replace x with any number you'd like. but its probably a word problem they want you to put as numbers, so bc you dont know what 'a number' is, you can pick a variable such as x to replace it with.
