Answer:2,500

Step-by-step explanation:

I'm guessing it is exponential, which means the balance increases by more over time, so the equation would be

500(1+0.002)^2=520.2002

or rounded to 502

Answer:

$983.45

Step-by-step explanation:

Given data

Principal= $700

Rate= 1.2%

Time= 3 years

The compound interest expression is given as

A= P(1+r)^t

A= 700(1+0.12)^3

A= 700(1.12)^3

A= 700*1.404928

A=$983.45

Hence the balance will be $983.45

Step-by-step explanation:

I calculated it logically

Questions :

a. Calculate the P-value for the appropriate two-sample z test, assuming that the data was based on n = 100. (Round your answer to four decimal places.)

b. Calculate the P-value for the appropriate two-sample z test, assuming that the data was based on n = 500. (Round your answer to four decimal places.)

c. Is the small P-value for n = 500 indicative of a difference that has practical significance

Answer :

0.1574

0.00157

Yes

Step-by-step explanation:

Hypothesis :

H0 : μ1 - μ2 = 0

H1 : μ1 - μ2 ≠ 0

Given :

x1 = 60.7 ; x2 = 60.5 ; s1 = 1 ; s2 = 2

Based on n = 100

Test statistic, Z :

Z = (x1 - x2)/[√(s1²/n1 + s2²/n2 )]

x1 - x2 = 60.7 - 60.5 = 0.2

0.2 / √(1²/100 + 1²/100 )]

0.2 / √0.02

Z = 1.414

The Pvalue from Zscore :

P(Z < 1.414) = 0.1574

B.)

For n = 500

Z = (x1 - x2)/[√(s1²/n1 + s2²/n2 )]

x1 - x2 = 60.7 - 60.5 = 0.2

0.2 / √(1²/500 + 1²/500 )]

0.2 / √0.004

Z = 3.162

The Pvalue from Zscore :

P(Z < 3.162) = 0.00157

Yes, the small Pvalue for n = 500 is indicative of a difference with practical significance ; as the Pvalue are compare with the α to make about a Decison about our hypothesis.

Answer:

[tex]\frac{1}{12}[/tex] more sandwich

Step-by-step explanation:

Very simple. Just subtract the amount Emma ate from the amount John ate.

[tex]\frac{4}{12} - \frac{3}{12} = \frac{1}{12}[/tex]

Hope this answer helped! :)

Answer:

John ate [tex]\frac{1}{12}[/tex] of a sandwich more than Emma.

Step-by-step explanation:

In order to find out how much more sandwich did John eat than Emma we just need to find the difference between the amounts that they ate, and so we get...

[tex]\frac{4}{12} - \frac{3}{12} = \frac{1}{12}[/tex]

Therefore John ate [tex]\frac{1}{12}[/tex] of a sandwich more than Emma.

Answer:

She buys 3 pairs from store a.

So divide the 110.25 by 3.

You will get the amount that she spent for each pair.

Change 40% to a decimal which would be .40 then you multiply the amount she spent on each pair ($36.75) by the .40.

You will get 14.7 so you add $14.70 to the amount she spent on each and you will get The original price of each pair was $51.45.

The solution of system of equations is (5, 10)

Two or more expressions with an Equal sign is called as Equation.

The given system of equations are

y=2x ...(1)

y=x+5...(2)

Let us plug in equation 2 in equation 1

x+5=2x

Subtract x from both sides

x=5

Now plug in x value in equation 1

y=2×5

y=10

Hence, the solution of system of equations is (5, 10)

So, its more like this:

Using the polar form, a complex number with modulus r and argument θ may be written

z = r(cos 0 + j sin θ)

It follows immediately from Euler’s relations that we can also write this complex number in

exponential form as :

z = [tex]re^{j0}[/tex]

When using this form you should ensure that all angles are measured in radians and not degrees.

The exponential form of a complex number is in widespread use in engineering and science. Since z = r(cosθ + isinθ) and since eiθ = cosθ + isinθ we therefore obtain another way in which to denote a complex number: z = reiθ, called the exponential form.

I'm leaning towards the answer choices A. and C.

But I'm sure it's A because of the two, C has an x. That's the only difference they have.

Here's another example,

Let z=x+iy, its exponential form comes from identifying it as the point (x,y) in the (Argand) plane. This basically amounts to writing it in what would be polar form in the real plane. Writing it as:

z =reiθ

. If you graph the point (x,y) and treat it as a vector its easy to see that r=|z| and θ=tan−1(yx).

For purely real numbers, they are already in exponential form since they are equal to their modulus and θ=0.

Also, you can write:

Re(z)=z+z¯2

if you want to write it purely in terms of z. Both of your numbers are purely real and thus they are already in exponential form. I suppose if you wanted to be strict about it you could write it as:

|1−z|=|1−z|e0i

Answer:

5 10 16 17 18

Step-by-step explanation:

Using the box plot above, the 5 number summary is this :

Minimum = value at the starting point of the left whisker = 5

Lower quartile = value at the start point of the box = 10

Median = value marked in between the box = 16

Upper quartile = value at the end point of the box = 17

Maximum = value at the endpoint of the whisker = 18

Answer:

Probability that effect is real = 0.97

Step-by-step explanation:

Given data :

ratio of true to false = 0.7

Alpha level = 0.05

power of study = 0.8

Determine the probability that this effect is real

From the question we can deduce : 70% of events are real , 30% of events are not real

% of real effect = 0.8 * 70% = 56%

% of false effect = alpha level * percentage of unreal events

                          =  0.05 * 30% = 1.5%

summation of effects = 56 + 1.5 = 57.5%

Hence probability that the effect is real

= 56% / 57.5%

= 0.9739 ≈ 0.97

Answer:

The margin of error for this confidence interval is of 7.

Step-by-step explanation:

Confidence interval concepts:

A confidence interval has two bounds, a lower bound and an upper bound.

A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.

The margin of error is the subtraction between these bounds, divided by 2.

In this question:

The bounds are 32 and 46.

(46 - 32)/2 = 14/2 = 7

The margin of error for this confidence interval is of 7.

cylinder with a radius of 7cm and a height of 10 cm

find the value of each flower pot and divided it into 24000 cm³

flower pot = π r² h   =  π × 7² × 10   =  π490    =  1539.38 cm³

24000 cm³ / 1539.38 cm³  =  15.59  flower pots

so Carl could only FILL 15 flower pots

Carl is filling flowerpots with soil. Each flowerpot is a cylinder with a radius of 7cm and a height of 10 cm. If Carl has 24,000 cubic centimeters of soil. So, Carl could only fill 15 flower pots.

Suppose that the radius of considered right circular cylinder be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

The cylinder with a radius of 7cm and a height of 10 cm.

The flower pot = π r² h  

[tex]= \pi \times 7^2 \times h\\ = 490 \pi \\ = 1539.38 cm^3[/tex]

= 24000 cm³ / 1539.38 cm³  

=  15.59  flower pots

So, Carl could only fill 15 flower pots.

Answer:

174 15/16 lbs or 2799/16 lbs

Step-by-step explanation:

to find the difference of the weight of the winning fish and the avg fish, I'm assuming you just need to subtract the values from each other.

so first I'm just gonna convert the mixed numbers into improper fractions because its easier to do math that way (for me).

342 5/16 = 5477/16 winning fish

167 3/8 = 1339/8 avg fish

now I need to find the difference between them so I'll just subtract the smaller number from the bigger number.

5577/16 - 1339/8 = difference

but wait oh no, they don't have the same denominator, so I'll multiply the 1339/8 by 2/2 so that I get a number over 16.

5577/16 - 2678/16 = difference

2799/16 lbs or 174 15/16 lbs (if you want to convert it into a nice mixed number)
