Suppose that you borrow $3000.00 from a friend and promise to pay back $4935.00 in 3 years. What simple interest rate will you pay? The simple interest rate is % (Round to the nearest tenth as needed.)
Answer:
the simple interest rate is 18.00%
Step-by-step explanation:
The computation of the simple interest rate is shown below:
Amount = Principal × (1 + rate)^years
$4,935 = $3,000 × (1 + rate)^3
After solving it, the rate of percentage is 18.00%
Hence, the simple interest rate is 18.00%

You are dealt a card from a standard 52 card deck , what is the probability of getting an ace
Answer:
0.1538
Step-by-step explanation:
Probability of being dealt with an ace of a 8 =
= Number of ace + number of an 8 in the deck / Total number of cards in the deck
= (4+4) / 52 = 8/52 = 0.1538
Therefore 0.1538 is the required probability here.
Answer:
[see below]
Step-by-step explanation:
There are four aces in a standard deck of cards.
[tex]\frac{aces}{cards}=\frac{4}{52}= 0.076923076923...[/tex]
0.076923076923... ≈ 0.077
0.077 = 7.7%
There is an approximate 7.7 percent chance that you will get an ace.
Hope this helps.
Give the angle classification of the triangle
with side lengths 3 cm, 5 cm, and 7 cm.
Given:
The sides of a triangle are 3 cm, 5 cm, 7 cm.
To find:
The angle classification of the given triangle.
Solution:
Let a,b,c are the three sides of a triangle ABC, where c is the longest side.
1. Triangle ABC is acute, if [tex]c^2<a^2+b^2[/tex].
2. Triangle ABC is acute, if [tex]c^2=a^2+b^2[/tex].
3. Triangle ABC is acute, if [tex]c^2>a^2+b^2[/tex].
The sum of square of two smaller sides is
[tex]3^2+5^2=9+25[/tex]
[tex]3^2+5^2=34[/tex]
In the given triangle 7 cm is the longest sides. So,
[tex]7^2=49[/tex]
It means,
[tex]7^2>3^2+5^2[/tex]
Since [tex]c^2>a^2+b^2[/tex], therefore, the triangle ABC is an acute triangle.

How much would you need to deposit in an account now in order to have $3000 in the account in 15 years? Assume the account earns 3% interest compounded monthly.
Answer:
Principal = Total ÷ (1 + Rate)^years
That formula is found here: http://www.1728.org/compint2.htm
Principal = 3.000 / (1.03) ^ 15
Principal = 3.000 / 1.5579674166
Principal = $1,925.59

Answer:
8,5
Step-by-step explanation:
x-y=3
x+y=13
2x=16
x=8, y=5
Answer: 8 and 5
Step-by-step explanation:
x - y = 3
x + y = 13
------------------ (add the two equations)
2x = 16
x = 8
8 + y = 13 (substitute x as 8 into one of the equations)
y = 5

Third-degree, with zeros of -2,-1, and 3, and passes through the point (2, 11).
Construct a polynomial function with the stated properties.
Answer:
[tex]P(x) = -\frac{11}{12}(x+2)(x+1)(x-3)[/tex]
Step-by-step explanation:
Zeros of a function:
Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.
Zeros of -2,-1, and 3
This means that:
[tex]P(x) = a(x - (-2))(x - (-1))(x - 3) = a(x+2)(x+1)(x-3)[/tex]
Passes through the point (2, 11).
This means that when [tex]x = 2, P(x) = 11[/tex]. We use this to find the leading coefficient.
[tex]P(x) = a(x+2)(x+1)(x-3)[/tex]
[tex]a(2+2)(2+1)(2-3) = 11[/tex]
[tex]-12a = 11[/tex]
[tex]a = -\frac{11}{12}[/tex]
So the polynomial is:
[tex]P(x) = -\frac{11}{12}(x+2)(x+1)(x-3)[/tex]
Evalúa ab-0.5bab−0.5ba, b, minus, 0, point, 5, b cuando a=1a=1a, equals, 1 y b=5b=5b, equals, 5.
Answer:
4.5
Step-by-step explanation:
Given the expression ab-0.5
We are to evaluate the expression if a =1 and b = 5
ab- 0.5
= 1(5) - 0.5
= 5 - 0.5
= 4.5
Hence the required result is 4.5

Maria has a recipe for pumpkin bread. She uses 3 ½ cups of flour to make 2 loaves of pumpkin bread. Alex will follow the same recipe. He will make b loaves of pumpkin bread using f cups of flour. Write an equation that represents the relationship between b and f.
Answer:
b + 1.75f
Step-by-step explanation:
1.75 cups are used for every loaf of pumpkin bread.
Answer:
f(4/7)=b
Step-by-step explanation:
3+1/2=7/2
(7/2)x=2
x=4/7
the constant of the equation is 4/7
so take f and b and put f in place for 7/2 cups and b for 2 loaves of bread.
f(4/7)=b
Hope that helps :)
Statistics - Please Help!!!
The question is in the screenshot.
Answer: See the table below (attached image)
SSb = 2345SSt = 5639DFb = 5DFw = 54MSb = 469=============================================================
Explanation:
I'll start at the right side of the table and work my way toward the left side.
I recommend you have a one way ANOVA formula sheet handy. Such a formula sheet should be located somewhere in the ANOVA chapter of your stats textbook, or toward the appendix section. There are various free online resources to search out as well.
On that formula sheet you should find that
(MSb)/(MSw) = F
where MSb and MSw are the mean squares between and within respectively.
We can find the value of MSb like so
(MSb)/(MSw) = F
MSb = F*MSw
MSb = 7.682*61
MSb = 468.602
This rounds to 469, so we'll go with MSb = 469. The reason I'm rounding is that I've done a similar problem in the past, and the computer system wanted me to round to the nearest whole number. Also, note how every value of the table given to us consists of whole numbers. Of course, your teacher may want you to keep the decimal value instead. So I would ask for clarification if possible.
Since we're going with MSb = 469, this means 469 goes in the last box of row 1.
-----------------------------------------------
Now go back to your reference sheet to locate this formula
MSw = (SSw)/(DFw)
Rearrange this formula to get
DFw = (SSw)/(MSw)
Now plug in the values we have from the table to find,
DFw = (SSw)/(MSw)
DFw = (3294)/(61)
DFw = 54 which goes in the box found in the second row.
-----------------------------------------------
Now recall that
DFb + DFw = df
where DFb is the degrees of freedom between and df is the total degrees of freedom, which in this case is 59.
Using the table and the value we found earlier, we can see that,
DFb = df - DFw
DFb = 59 - 54
DFb = 5 this goes in the second box of row one (ie above the 54).
-----------------------------------------------
Also on your formula sheet, you should see something like
MSb = (SSb)/(DFb)
where each lowercase 'b' stands for "between", and the other abbreviations are what were discussed earlier.
That formula rearranges into
SSb = (DFb)*(MSb)
Then we can use the values we calculated earlier to find
SSb = (DFb)*(MSb)
SSb = (5)*(469)
SSb = 2345 this goes in the first box of row one.
----------------------------------------------
Lastly, computing the total sum of squares (SSt) will simply involve us adding the two SSb and SSw values to get
SSt = SSb + SSw
SSt = 2345 + 3294
SSt = 5639 this goes in the box of row three.
----------------------------------------------
To summarize, we have these values to fill into the table
SSb = 2345SSt = 5639DFb = 5DFw = 54MSb = 469where we have these abbreviations
SS = sum of squaresMS = mean squareDF = degrees of freedomb = betweenw = withinCheck out the diagram below for the filled in values.
To summarize the formulas used, we basically have the template of
MS = (SS)/(DF)
for both between and within. And we also have the formula F = (MSb)/(MSw). So effectively, the values are found through various division formulas or rearrangements of such. I'm referring to working along any given row. For any given column, we add up the values to get the totals, though that of course does not apply to MS or F.
Admittedly, ANOVA tables and concepts can be confusing because there are a lot of variables and steps going on. But once you get used to it, it's not too bad if you can see how the patterns are emerging (the division and additions I was referring to earlier).
