Answer:
a. No the null hypothesis cannot be rejected at 1% level of significance as the calculated value of z= 2.222 which lies with in 2.333
b. Yes for the Type 1 Error of 2.5% we say the toaster oven consumes more than 250 W of power because the calculated value 2.22 lies outside the region for 1.96
c. The cut-off at 2.5% level of significance is 258.82 W.
d. 0.85 is the area for Type 2 error.
e. The cut-off at 1% level of significance is 260.485W.
f. 0.154 is the area for Type 2 Error
g. The Type 2 Error is increased when Type 1 Error is decreased.
h. The Type 1 Error is decreased when Type 2 Error is increased .

Dean has built a ferris wheel in his backyard. It has a diameter of 10 feet and completes 30 revolutions per minute. Sketch a quick graph and find the period of the function that describes the height above the ground of a seat on the outside edge of this ferris wheel.
Answer: Period = 2 seconds
Graph is shown below
========================================================
Explanation:
1 minute = 60 seconds
We have 30 revolutions every 60 seconds, so we can write the ratio
30 rev: 60 sec
Divide both parts by 30 to turn that "30 rev" into "1 rev"
30 rev: 60 sec
30/30 rev: 60/30 sec
1 rev : 2 sec
This tells us that each full revolution takes 2 seconds. This is the period of the ferris wheel. The period is the length of each cycle.
The cyclic or periodic nature of this motion heavily implies we'll be dealing with a sine or cosine function of some kind. Let's go with sine.
Side note: cosine is really a sine function in disguise (it's just a phase shifted version of it).
---------------------
The general sine curve equation is
y = A*sin(B(x-C)) + D
where
|A| = amplitudeB = 2pi/T with T being the periodC handles phase shifts (left and right shifting)D handles vertical shifting, and y = D is the equation of the midline---------------------
The wheel is 10 feet in diameter, so 10/2 = 5 is the radius. This is also the amplitude because it is the distance from the midline to either the highest point (10 ft) or lowest point (0 ft). So A = 5.
Since T = 2 is the period, this means,
B = 2pi/T
B = 2pi/2
B = pi
We don't have any phase shifts to worry about so C = 0.
The midline is D = 5 since this is halfway up
----------------------
Putting all the pieces together, we get this sine equation
y = A*sin(B(x-C)) + D
y = 5*sin(pi*(x-0)) + 5
y = 5*sin(pi*x) + 5
The graph is shown below.
x = time in seconds, y = height of the seat

Y is equal to 10 less than 4 times a number.
Answer:
y=4x-10
Step-by-step explanation:
This would be you equation to graph your line since 4 times a number would be 4x and less then 10 would be negative 10. Remember that -10 is the y-int and 4 is the slope of the line (Use rise over run).
Two cars leave the same point at the same time traveling in opposite directions. One car travels west at 20 mph and the other travels east at 60 mph. In how many hours will they be 280 miles apart?
-Please provide step by step :)
Answer:
3.5 hours
Step-by-step explanation:
It is given that,
Velocity of first car, v = 20 mph
Velocity of second car, v' = 60 mph
They are moving in opposite direction. Their relative speed is given by :
V = 20 mph + 60 mph = 80 mph
Distance, d = 280 miles
So,
[tex]t=\dfrac{d}{V}\\\\t=\dfrac{280}{80}\ h\\\\t=3.5\ h[/tex]
Hene, they will be 280 mile apart in 3.5 hours.
Median for 49 32 67 55 58

show how you would use partial products to solve 3x12
Answer:
(10x3) + (2x3)
Step-by-step explanation:
break down the number with two place values (just for this case) and those numbers would be 10+2 so then you multiply each number by 3
:) hope this helps doll!
The required product of 3 × 12 by the partial product method is 36.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The partial product of 3 × 12 is given as
= 3 × (10 + 2)
= 3 × 10 + 3 × 2
= 30 + 6
= 36
Thus, the required product of 3 × 12 by the partial product method is 36.

Is 3125 a perfect cube ? If not find the smallest number by which 3125 must be multiplied so that the product becomes a perfect cube.
Answer:
Yes it is
Step-by-step explanation: 3125 is a prefect cube
Answer:
5
Step-by-step explanation:
3125 is not a perfect cube.
The cubes around it are 14^3=2744 and 15^3=3375.
It seems like the only way to find the smallest number to multiply 3125 to make it a perfect cube is to guess and check.
3125*2=6250 cube root is 18.4
3125*3=9375 cube root is 21.08
3125*4=12500 cube root is 23.2
3125*5=15625 cube root is 25, which makes it a perfect cube.
You have to multiply by 5 to make 3125 a perfect cube.
