Answer:
Step-by-step explanation:
amount earned in 1 hr = $8
therefore, amount earned in 12 hrs = 12 x 8 = 96
let the amount earned in 1 hr be x
therefore, the amount earned in 12 hours = 12x

The body weight of a healthy 3 month-old colt should be about μ = 60 kg. (Source: The Merck Veterinary Manual, a standard reference manual used in most veterinary colleges.)
(a) If you want to set up a statistical test to challenge the claim that μ = 60 kg, what would you use for the null hypothesis H0?
μ ≠ 60
μ > 60
μ = 60
μ < 60
(b) In Nevada, there are many herds of wild horses. Suppose you want to test the claim that the average weight of a wild Nevada colt (3 months old) is less than 60 kg. What would you use for the alternate hypothesis H1?
μ > 60
μ < 60
μ ≠ 60
μ = 60
(c) Suppose you want to test the claim that the average weight of such a wild colt is greater than 60 kg. What would you use for the alternate hypothesis?
μ = 60
μ < 60
μ ≠ 60
μ > 60
(d) Suppose you want to test the claim that the average weight of such a wild colt is different from 60 kg. What would you use for the alternate hypothesis?
μ = 60
μ ≠ 60
μ > 60
μ < 60
(e) For each of the tests in parts (b), (c), and (d), would the area corresponding to the P-value be on the left, on the right, or on both sides of the mean?
both; left; right
right; left; both
left; right; both
left; both; right
Answer:
a
The null hypothesis will be [tex]H_o : \mu = 60 \ kg[/tex]
b
The alternative hypothesis will be [tex]H_a : \mu < 60[/tex]
c
The alternative hypothesis will be [tex]H_a : \mu > 60[/tex]
d
The alternative hypothesis will be [tex]H_a : \mu \ne 60[/tex]
e
left; right; both
Step-by-step explanation:
Considering question a
The body weight of the colt is [tex]\mu = 60 \ kg[/tex]
The null hypothesis will be [tex]H_o : \mu = 60 \ kg[/tex]
Considering question b
Given that we want to test the claim that the average weight of a wild Nevada colt is less than 60 kg , then
The alternative hypothesis will be [tex]H_a : \mu < 60[/tex]
Considering question c
Given that we want to test the claim that the average weight of such a wild colt is greater than 60 kg , then
The alternative hypothesis will be [tex]H_a : \mu > 60[/tex]
Considering question d
Given that we want to test the claim that the average weight of such a wild colt is different from 60 kg , then
The alternative hypothesis will be [tex]H_a : \mu \ne 60[/tex]
Considering question e
For question b , the corresponding p-value will be on the left because the average weight is less than 60 kg
For question c , the corresponding p-value will be on the right because the average weight is more than 60 kg
For question d , the corresponding p-value will be on both because the average weight is different from 60 kg
If triangle ABC is similar to triangle ZXY, measure of angle A = 50, and measure of angle C = 30,
what is measure of angle X?
1) 30
2) 50
3) 80
4) 100
Answer:
4) 100
Step-by-step explanation:
If ABC is similar to ZXY,
Angle A=Z, B=X, and C=Y.
Since A=50 and C=30, we know that Z=50, and Y=30.
Using the fact that all triangle angles add up to 180 degrees,
we get 180-50-30= 4) 100

If 6000 dollars is invested in a bank account at an interest rate of 9 per cent per
year,
Find the amount in the bank after 8 years if interest is compounded annually:
Find the amount in the bank after 8 years if interest is compounded quarterly:
Find the amount in the bank after 8 years if interest is compounded monthly:
Finally, find the amount in the bank after 8 years if interest is compounded
continuously:
Answer:
(1) $11955.38
(2) $12228.62
(3) $12293.527
(4) $12326.6
Step-by-step explanation:
Compound interest is given by
A= P( 1 + r/n)^n*t
A= Final amount
P = initial amount = 6000
r = interest rate = 9% = 0.09
n = number of times interest applied per time period
t = number of time periods elapsed
(1) Compounded annually
n = 1 , t = 8
A = 6000( 1+ 0.09/1) ^1*8
A = 6000( 1.09) ^8 = $11955.38
(2) compounded quarterly
n = 4 , t = 8
A = 6000( 1+ 0.09/4) ^4*8
= 6000( 1.0225)^32 = $12228.62
(3) compounded monthly
n = 12 , t = 8
A = 6000( 1+0.09/12)^12*8 = $12293.527
(4) compounded continuously
A = P* e^rt
r = 0.09 , t = 8
= 6000* e^0.09*8
= 6000* e^0.72 = $12326.6
The Amount according to the given scenario will be:
(1) $11955.38
(2) $12228.62
(3) $12293.527
(4) $12326.6
The given values are:
Initial amount,
P = 6000Interest rate,
r = 9% or 0.09(a)
If interest compounded annually then,
n = 1t = 8→ [tex]A = P(\frac{1+r}{n} )^n\times t[/tex]
[tex]= 6000(\frac{1+0.09}{1} )^1\times 8[/tex]
[tex]= 11955.38[/tex] ($)
(b)
If interest compounded quarterly then,
n = 4t = 8→ [tex]A = P(\frac{1+r}{n} )^n\times t[/tex]
[tex]= 6000(\frac{1+0.09}{4} )^4\times 8[/tex]
[tex]= 12228.62[/tex] ($)
(c)
If interest compounded monthly then,
n = 12t = 8→ [tex]A = P(\frac{1+r}{n} )^n\times t[/tex]
[tex]=P(\frac{1+0.09}{12} )^{12}\times 8[/tex]
[tex]= 12293.527[/tex] ($)
(d)
If interest compounded continuously then,
r = 0.09t = 8→ [tex]A = P\times e^{rt}[/tex]
[tex]= 6000\times e^{0.09\times 8}[/tex]
[tex]= 6000\times e^{0.72}[/tex]
[tex]= 12326.6[/tex] ($)

The ocean liner Titanic lies under 12500 feet of water at the bottom of the Atlantic Ocean. (The density of water is 62.4 lb/ft3.)
(a) What is the water pressure at the Titanic? (Give your answer in both pounds per square foot and pounds per square inch.)
I got 780000 lbs/ft^2 which is equal to about 5416.67 lbs/in^2
(b) What is the total force on a circular porthole (window) of diameter 7 feet standing vertically with its center at the depth of the Titanic?
Answer:
a)[tex]780000 lb/ft^2[/tex]
b)Total force = 30017917.805 lb
Step-by-step explanation:
Depth of titanic = 12500 feet
Density of water =[tex]62.4 lb/ft^3[/tex]
a)Water pressure at the Titanic =[tex]depth \times density = 12500 \times 62.4=780000 lb/ft^2[/tex]
b)
Set up a integral that gives a total force
Diameter = 7 feet
[tex]Radius = \frac{7}{2}\\x^2+y^2=(\frac{7}{2})^2\\r^2+h^2=(\frac{7}{2})^2\\r=\sqrt{(\frac{7}{2})^2-h^2}[/tex]
Rectangular strip area =[tex]2r \Delta h[/tex]
Pressure = 62.4(12500-h)
Force =[tex]Pressure \times Area[/tex]
Force =[tex]62.4(12500-h) \times 2(\sqrt{(\frac{7}{2})^2-h^2}) \Delta h[/tex]
Total force = [tex]\int\limits^{\frac{7}{2}}_{\frac{-7}{2}} {124.8(12500-h)\sqrt{(\frac{7}{2})^2-h^2} \, dh[/tex]

Knowing the meaning of metric system prefixes can help you write your own conversion factors. In the metric system, the base unit for mass is the gram. What do you think the conversion factor for gram-to-kilograms would be?
Answer:
1000grams = 1kilogram
Step-by-step explanation:
The kilogram is the standard international unit for measuring the mass of an object. Other lower units are the grams (g), milligrams (mg) etc.
Metric systems are systems of units for measuring quantity of an object. Since gram is a lower unit for kilogram, hence kilogram is a higher unit. The
conversion unit is expressed as;
1000grams = 1kilogram

Find the maximum and minimum values of the function g ( θ ) = 5 θ − 6 sin ( θ ) on the interval [ 0 , π /2 ]
Answer:
Minimum value of the given function is 0
Maximum value of the given function
[tex]\frac{5\pi -12}{6}[/tex]
Step-by-step explanation:
Step(i):-
Given function g ( θ ) = 5 θ − 6 sin ( θ ) ...(i)
Differentiating equation (i) with respective to 'θ'
g¹ ( θ ) = 5 − 6 cos ( θ ) ...(ii)
g¹ ( θ ) = 5 − 6 cos ( θ ) =0
5 = 6 cos ( θ )
cos ( θ ) = 5 /6
Step(ii):-
Again Differentiating equation (ii) with respective to 'θ'
g¹¹ ( θ ) = − 6 (-sinθ ) = 6sinθ
Given interval
θ = 0 and θ= π/2
g ( 0 ) = 5 (0) − 6 sin ( 0 ) = 0
g(π/2) = 5(π/2) - 6 sin (π/2)
= 5(π/2) - 6
