Answer:
Step-by-step explanation:
With regards to the factor 'walking device used', the ANOVA conducted on the cadence data revealed a main effect of walking device, and also with the results of the experiment giving rise to a p - value less than 0.05, we can reject the null hypothesis which says, there is no effect of the walking device factor.
We can thus conclude that there is not enough statistics evidence to prove that there is no interaction between the two factors or that there is no effect of the walking device given the cadence data.
the principal p is borrowed at a simple interest rate r for a period of time t. find the simple interest owed for the use of the money
Answer:
The simple interest is Prt
The simple interest on the money will be $24300
Step-by-step explanation:
The complete question is shown below
The principal P is borrowed at simple interest rate r for a period of time t. Find the simple interest owed for the use of the money. Assume 360 days in a year. P=$18,000, r=7.5%, t=18 months
Principal = P
Interest rate = r
Time period = t
simple interest owed for the use of the money will be gotten as below
The percentage of the principal that will be owed per unit period is the rate r
The total rate that it will be involved in this time period will be the product of the rate and the time = r x t = rt
Finally, to know the amount of interest that this rate will result to, we multiply the total rate in the time period by the original principal borrowed
Total interest = Prt
For a simple interest on the principal P = $18,000,
the interest rate = 7.5% = 7.5/100 = 0.075,
time period = 18 months
we assume the interested is calculated on a monthly basis
Simple interest = Prt
==> 18000 x 0.075 x 18 = $24300

Suggest changing to “On the graph of an exponential function representing growth, what happens to the slope of the graph as x increases?”
Answer:
If we have a growing exponential relation, we can write it as:
f(x) = A*r^x
Where A is the initial amount, r is the rate of growth, in this case, r > 1 (because is a growing exponential relation)
Now, the "slope" of the graph in x, is equal to the derivate of f(x) in that point, and we have:
f'(x) = A*(r^x)*ln(r)
Now, remember that r > 1, then ln(r) > 0.
then, f'(x) is a growing function as x grows, and f'(x) grows exponentially, this means that the slope of the graph also grows exponentially as x grows.

19.25 tons equal Lbs
Answer:
38500lbs
Step-by-step explanation:
2000 lbs is one tone
if we have 19.25 tons, we need to multiply 19.25x2000
The answer is 38500 lb
Answer:
38,500 pounds
Step-by-step explanation:
Every ton is 2,000 pounds.
We want to find out how many pounds are in 19.25 tons.
Set up a proportion.
pounds/tons=pounds/tons
2,000 pounds/ 1 ton= x pounds / 19.25 tons
2,000/1= x /19.25
x is being divided by 19.25. The inverse of division is multiplication. Multiply both sides by 19.25.
19.25*2,000/1= x/19.25 *19.25
19.25*2000=x
38,500=x
There are 38,500 pounds in 19.25 tons.
A local doctor’s office logged the number of patients seen in one day by the doctor for ten days. Find the means, median, range, and midrange of the patients seem in 10 days. 27 31 27 35 35 25 28 35 33 24
Answer:
Mean = 30, Median = 29.5, Range = 9 and Mid-range = 29.5.
Step-by-step explanation:
We are given that a local doctor’s office logged the number of patients seen in one day by the doctor for ten days.
Arranging the given data in ascending order we get;
24, 25, 27, 27, 28, 31, 33, 35, 35, 35.
(a) Mean is calculated by using the following formula;
Mean, [tex]\bar X[/tex] = [tex]\frac{\text{Sum of all values}}{\text{Total number of observations}}[/tex]
= [tex]\frac{27+ 31+ 27+ 35+ 35+ 25+ 28+ 35+ 33+ 24}{10}[/tex]
= [tex]\frac{300}{10}[/tex] = 30
So, the mean of the given data is 30.
(b) For calculating the median, we have to first have to observe that the number of observations (n) in the data is even or odd.
If n is odd, then the formula for calculating median is given by;Median = [tex](\frac{n+1}{2})^{th} \text{ obs.}[/tex]
If n is even, then the formula for calculating median is given by;Median = [tex]\frac{(\frac{n}{2})^{th} \text{ obs.}+ (\frac{n}{2}+1)^{th} \text{ obs.} }{2}[/tex]
Here, the number of observations is even, i.e. n = 10.
So, Median = [tex]\frac{(\frac{n}{2})^{th} \text{ obs.}+ (\frac{n}{2}+1)^{th} \text{ obs.} }{2}[/tex]
= [tex]\frac{(\frac{10}{2})^{th} \text{ obs.}+ (\frac{10}{2}+1)^{th} \text{ obs.} }{2}[/tex]
= [tex]\frac{(5)^{th} \text{ obs.}+ (6)^{th} \text{ obs.} }{2}[/tex]
= [tex]\frac{28+31}{2}[/tex]
= [tex]\frac{59}{2}[/tex] = 29.5
So, the median of the data is 29.5.
(c) The range of the data is given by = Highest value - Lowest value
= 35 - 24 = 9
So, the range of the data is 9.
(d) Mid-range of the data is given by the following formula;
Mid-range = [tex]\frac{\text{Highest value}+\text{Lowest value}}{2}[/tex]
= [tex]\frac{35+24}{2}[/tex] = 29.5
In triangle ΔABC, ∠C is a right angle and CD is the altitude to AB . Find the measures of the angles of the ΔCBD and ΔCAD if: Chapter Reference a m∠A = 20°
Answer:
1. ∆CBD: ∠B = 70°; ∠BCD = 20°; ∠ BDC = 90°
2. ∆CDA: ∠ACD = 70°; ∠A = 20°; ∠ ADC = 90°
Step-by-step explanation:
1. ∆DBC
In ∆ABC
∠A + ∠B + ∠C = 180°
20° + ∠B + 90 ° = 180°
∠B + 110 ° = 180°
∠DBC = ∠B = 70°
In ∆CBD
∠BDC = 90°
∠B + ∠BCD + ∠CBD = 180°
70° + ∠BCD + 90 ° = 180°
∠BCD + 160° = 180°
BCD = 20°
2. ∆CAD
∠A + ∠ACD + ∠ADC = 180°
20° + ∠ACD + 90° = 180°
∠ACD + 110° = 180°
∠ACD = 70°
Set up and evaluate the optimization problem. You are constructing a cardboard box from a piece of cardboard with the dimensions 4 m by 8 m. You then cut equal-size squares from each corner so you may fold the edges. What are the dimensions (in m) of the box with the largest volume
Answer:
[tex]Shorter\ side=4-2\times 0.845=2.31\ m\\Longest\ side=8-2\times 0.845=6.31\ m\\Height=0.845\ m[/tex]
Step-by-step explanation:
Given that , dimension of the cardboard is 4 m by 8 m.
Lets the dimensions of the square is x m by x m.
The volume after cutting the equal size of square from all the four corners is given as
[tex]V=x\times (4-2x)\times (8-2x)\\V=x\times (32-16x-8x+4x^2)\\V=x\times (4x^2-24x+32)\\V=4x^3-24x^2+32x\\[/tex]
For the maximum volume
[tex]\dfrac{dV}{dx}=12x^2-48x+32=0\\3x^2-12x+8=0\\[/tex]
For maximum value of volume , the value of x will be 0.845
x= 0.845
Therefore the dimensions will be
[tex]Shorter\ side=4-2\times 0.845=2.31\ m\\Longest\ side=8-2\times 0.845=6.31\ m\\Height=0.845\ m[/tex]
The volume of a shape is the amount of space in the shape.
The dimensions that produce the largest volume are: 2.31 m by 6.31 m by 0.845 m
The dimensions of the cardboard is given as:
[tex]\mathbf{Length = 4m}[/tex]
[tex]\mathbf{Width = 8m}[/tex]
Assume the cut-out is x.
So, the dimension of the box is:
[tex]\mathbf{Length = 4 - 2x}[/tex]
[tex]\mathbf{Width = 8 - 2x}[/tex]
[tex]\mathbf{Height = x}[/tex]
So, the volume of the box is:
[tex]\mathbf{V = (4 - 2x)(8 - 2x)x}[/tex]
Expand
[tex]\mathbf{V = 32x -24x^2 + 4x^3}[/tex]
Differentiate
[tex]\mathbf{V' = 32 -48x + 12x^2}[/tex]
Set to 0
[tex]\mathbf{32 -48x + 12x^2 = 0}[/tex]
Divide through by 4
[tex]\mathbf{8 -12x + 3x^2 = 0}[/tex]
Rewrite as:
[tex]\mathbf{3x^2-12x +8 = 0}[/tex]
Using a calculator, we have:
[tex]\mathbf{x = 0.845,\ 3.155}[/tex]
3.155 is greater than the dimension of the box.
So, we have:
[tex]\mathbf{x = 0.845}[/tex]
Recall that:
[tex]\mathbf{Length = 4 - 2x}[/tex]
[tex]\mathbf{Width = 8 - 2x}[/tex]
[tex]\mathbf{Height = x}[/tex]
So, we have:
[tex]\mathbf{Length = 4 - 2 \times 0.845 = 2.31}[/tex]
[tex]\mathbf{Width = 8 - 2 \times 0.845 = 6.31}[/tex]
[tex]\mathbf{Height = 0.845}[/tex]
Hence, the dimensions that produce the largest volume are: 2.31 m by 6.31 m by 0.845 m

Estimate the difference of 645 and 273.
Answer:
350
Step-by-step explanation:
In this situation it seems like we should be rounding to 50 because the numbers work well that way, and it is nice number commonly unsed in these situaltions. So, 645 rounded to the nearentest 50 would be 650. And 273 rounded to the nerent 50 would be 300. Now if we subtract 300 from 650, (650-300) we will get 350.

Answer:
44π rads per seconds
Step-by-step explanation:
Already the speed of the 4 foot blade is given as 22 revolutions per sec.
What we have to do is just to convert the 22 revolutions per second to radians.
1 rev = 360°
360° = 2π
So the speed is actually equal to
22 *360 = 7920° per second

Manuel ordered pizza for a party. A vegetable pizza has 6 slices per pie. A cheese pizza has 8 slices per pie. Manuel ordered four times as many cheese pizzas as vegetable pizzas, for a total of 152 slices. How many pizzas did Manuel order? 15 20 30 40
Answer:
20 Pizza
Step-by-step explanation:
Let the number of vegetable pizza be x
Given that
Manuel ordered four times as many cheese pizzas as vegetable pizzas
the number of cheese pizza = 4x
1. no of slice in 1 vegetable pizza pie = 6
no of slice in x vegetable pizza pie = 6x
2. no of slice in 1 cheese pizza pie = 8
no of slice in 4x cheese pizza pie = 8*4x = 32x
Total no of slice for x vegetable pizza and 4x cheese pizza = 6x+32x = 38x
Given that
total no. of 152 slices, therefore
38x = 152
=> x = 152/38 = 4
Thus, no. of vegetable pizza ordered = 4
no. of cheese pizza ordered = 4x = 4*$ = 16
Total no of pizza ordered = 16+4 = 20 (answer)

It is believed that 11% of all Americans are left-handed. In a random sample of 100 students from a particular college with 10123 students, 14 were left-handed. Find a 98% confidence interval for the percentage of all students at this particular college who are left-handed.
Answer:
Step-by-step explanation:
We can calculate this confidence interval using the population proportion calculation. To do this we must find p' and q'
Where p' = 14/100= 0.14 (no of left handed sample promotion)
q' = 1-p' = 1-0.14= 0.86
Since the requested confidence level is CL = 0.98, then α = 1 – CL = 1 – 0.98 = 0.02/2= 0.01, z (0.01) = 2.326
Using p' - z alpha √(p'q'/n) for the lower interval - 0.14-2.326√(0.14*0.86/100)
= -2.186√0.00325
= -2.186*0.057
= 12.46%
Using p' + z alpha √(p'q'/n)
0.14+2.326√(0.14*0.86/100)
= 0.466*0.057
= 26.5%
Thus we estimate with 98% confidence that between 12% and 27% of all Americans are left handed.
