Answer:
MAD = 2
Step-by-step explanation:
First We'll find the mean of data
Mean = [tex]\frac{20}{5}[/tex]
Mean = 4
Then, we'll find absolute deviation
=> |4-3| = 1
=> |4-2| = 2
=> |4-1| = 3
=> |4-1| = 3
=> |4-3| = 1
Now, taking the mean of these absolute deviations:
MAD = [tex]\frac{1+3+3+2+1}{5}[/tex]
MAD = [tex]\frac{10}{5}[/tex]
MAD = 2
find -8 ÷ -1/2=

A geometric sequence is represented by a Subscript n Baseline = a Subscript 1 Baseline r Superscript n minus 1. What is the fifth term of a geometric sequence where a Subscript 1 Baseline = 4,096 and the common ratio is Negative one-fourth?
Answer:
16Step-by-step explanation:
Given the nth term of a geometric sequence represented as [tex]Tn = a_1r^{n-1}[/tex]
[tex]a_1[/tex] = first term of the sequence
n = number of terms
r = common ratio
Given [tex]a_1 = 4,096,\ r = -\frac{1}{4} , n = 5[/tex](fifth term of the sequence)
[tex]T_5 = 4,096(-\frac{1}{4} )^{5-1}\\ T_5 = 4,096(-\frac{1}{4} )^{4}\\T_5 = 4,096(\frac{1}{256} )\\T_5 = 16[/tex]
The fifth term of the geometric sequence is 16

Use the given information to find the measures of all angles formed by parallel lines a and b, and transversal m.
One angle is 25° greater than another.
Answer:
Either [tex]77.5^{o}[/tex] or [tex]102.5^{o}[/tex]
Step-by-step explanation:
Given that : one angle is [tex]25^{0}[/tex] greater than another. Let the two angles be represented by a and b. Since one angle is [tex]25^{0}[/tex] greater than another, then:
b = a + [tex]25^{0}[/tex]
But;
a + b = [tex]180^{o}[/tex] (sum of angles on a straight line)
a + a + [tex]25^{0}[/tex] = [tex]180^{o}[/tex]
2a = [tex]180^{o}[/tex] - [tex]25^{0}[/tex]
a = [tex]77.5^{o}[/tex]
b = [tex]77.5^{o}[/tex] + [tex]25^{0}[/tex] = [tex]102.5^{o}[/tex]
Therefore the measures of all angles formed by the lines is either [tex]77.5^{o}[/tex] or [tex]102.5^{o}[/tex].
At a farmers' market, Frederick buys 4 pounds of apples and 14 pounds of cherries for $38.64. At the same farmers' market, Wilhelmina buys 12 pounds of apples and 7 pounds of cherries for $27.72. Determine the price per pound of apples and cherries at the farmers' market.
Answer:
Price per pound of apple=$0.84
Price per pound of cherry=$2.52
Step-by-step explanation:
Let apple=a
Let cherry =c
Fredrick
4a+14c=38.64. (1)
Wilhelmina
12a+7c=27.72. (2)
Multiply (1) by 1 and (2) by 2
4a+14c=38.64. (3)
24a+14c=55.44 (4)
Subtract (3) from (4)
20a= 16.8
a=16.8/20
a=0.84
Substitute a=0.84 into equ (1)
4a+14c=38.64
4(0.84)+14c=38.64
3.36+14c=38.64
14c=38.64-3.36
14c=35.28
c=35.28/14
c=2.52
Price per pound of apple=$0.84
Price per pound of cherry=$2.52
Check
4(0.84)+14(2.52)
3.36+35.28=38.64
12a+7c=27.72
12(0.84)+7(2.52)
=10.08+17.64
=27.72
Student Friendly Bank pays a simple interest rate of 2.5% per year. Neighborhood Bank pays a compound interest rate of 2.1% per year, compounded monthly.
The question is incomplete:
Student Friendly Bank pays a simple interest rate of 2.5% per year. Neighborhood Bank pays a compound interest rate of 2.1% per year, compounded monthly.
Which bank will provide the largest balance if you plan to invest $10,000 for 10 years? For 20 years?
Answer:
-The bank that provides the largest balance if you plan to invest $10,000 for 10 years is Student Friendly Bank.
-The bank that provides the largest balance if you plan to invest $10,000 for 20 years is Neighborhood Bank.
Step-by-step explanation:
First, you have to calculate the balance if you invest the money in Student Friendly Bank. To do it, you have to use the simple interest formula to calculate the future value:
FV=PV(1+rt)
FV= future value
PV= present value
r= rate
t=time
-10 years:
FV= 10,000(1+(0.025*10))
FV= 10,000(1+0.25)
FV=10,000(1.25)
FV=12,500
-20 years:
FV= 10,000(1+(0.025*20))
FV= 10,000(1+0.5)
FV=10,000(1.5)
FV=15,000
Second, you have to calculate the balance if you invest the money in Student Neighborhood Bank. To do it, you have to use the compound interest formula to calculate the future value:
FV=PV(1+(r/m))^mt
FV= future value
PV= present value
r= rate
t=time
m=number compounding periods per year
-10 years:
FV=10,000*(1+(0.021/12))^12*10
FV=10,000*(1+0.00175)^120
FV=10,000*(1.00175)^120
FV=12,334.5
-20 years:
FV=10,000*(1+(0.021/12))^12*20
FV=10,000*(1+0.00175)^240
FV=10,000*(1.00175)^240
FV=15,214
According to this, the bank that provides the largest balance if you plan to invest $10,000 for 10 years is Student Friendly Bank because it will provide $12,500 and Neighborhood Bank will provide $12,334.5.
The bank that provides the largest balance if you plan to invest $10,000 for 20 years is Neighborhood Bank because it will provide $15,214 and Student Friendly Bank will provide $15,000.
I will make you as brainliest!!! Please help me!!! Suggest a committee that needs 5 members to plan a fundraiser. The candidates consist of 24 girls and 16 boys. What is the probability that at most 2 girls will be on the committee?
Answer:
69/195
Step-by-step explanation:
So u add 24 and 16 to find the total number of people who are there
The total is 40
If they want at least 2 girls
So one of the probability for one girl is 24/40 which is 3/5
The other probability of another girl is 23/39
So u multiply 23/39 by 3/5 which is 69/195
Correct me if this is wrong
Sorry
Answer:
30.77%.
Step-by-step explanation:
There are a total of 40 members.
24 girls 16 boys.
Prob( 0 girls being chosen - so all boys ) = 16/40 * 15/39*14/38* 13/37*12/36 = 0.0063956
Prob( first one to be chosen is a girl then all boys) = (24/40*16/39*15/38*14/37*13/36) = 0.013276
There are 5 ways of 1 girl being chosen so
Prob(1 girl out of 5 chosen) = 0.013276 * 5 = 0.06638
Prob( First 2 chosen are girls then all boys) = 24/40 * 23/39 * 16/38*15/37*14/36
= 0.023489
Number of ways of 2 girls being chosen is 5C2 and so the probability of 2 girls
= 0.023489 * 5C2
= 0.023489 * 10
= 0.23489.
Required probability = 0.23489 + 0.06638 + 0.0063956.
= 0.3076656
= 30.77% to the nearest hundredth.

How many Positive Integers are there between 20 to 100 exclusively?
Select one:
a. 70
b. 80
c. 81
d. 79
Answer:
79
Step-by-step explanation:
There is a cool easy way to solve this kind of problem. If a range is given, and the entire range increases in incrememnts of 1, then you can find the number intergers inclusive by taking the first number and subtracting it from the last and adding 1. Since in this problem you want it exclusive, we can rewrite the range to 21-99.
99-21 +1 = 78 + 1 = 79

If A(4 -6) B(3 -2) and C (5 2) are the vertices of a triangle ABC fine the length of the median AD from A to BC. Also verify that area of triangle ABD = Area of triangle ACD
Answer:
a) The median AD from A to BC has a length of 6.
b) Areas of triangles ABD and ACD are the same.
Step-by-step explanation:
a) A median is a line that begin in a vertix and end at a midpoint of a side opposite to vertix. As first step the location of the point is determined:
[tex]D (x,y) = \left(\frac{x_{B}+x_{C}}{2},\frac{y_{B}+y_{C}}{2} \right)[/tex]
[tex]D(x,y) = \left(\frac{3 + 5}{2},\frac{-2 + 2}{2} \right)[/tex]
[tex]D(x,y) = (4,0)[/tex]
The length of the median AD is calculated by the Pythagorean Theorem:
[tex]AD = \sqrt{(x_{D}-x_{A})^{2}+ (y_{D}-y_{A})^{2}}[/tex]
[tex]AD = \sqrt{(4-4)^{2}+[0-(-6)]^{2}}[/tex]
[tex]AD = 6[/tex]
The median AD from A to BC has a length of 6.
b) In order to compare both areas, all lengths must be found with the help of Pythagorean Theorem:
[tex]AB = \sqrt{(x_{B}-x_{A})^{2}+ (y_{B}-y_{A})^{2}}[/tex]
[tex]AB = \sqrt{(3-4)^{2}+[-2-(-6)]^{2}}[/tex]
[tex]AB \approx 4.123[/tex]
[tex]AC = \sqrt{(x_{C}-x_{A})^{2}+ (y_{C}-y_{A})^{2}}[/tex]
[tex]AC = \sqrt{(5-4)^{2}+[2-(-6)]^{2}}[/tex]
[tex]AC \approx 4.123[/tex]
[tex]BC = \sqrt{(x_{C}-x_{B})^{2}+ (y_{C}-y_{B})^{2}}[/tex]
[tex]BC = \sqrt{(5-3)^{2}+[2-(-2)]^{2}}[/tex]
[tex]BC \approx 4.472[/tex]
[tex]BD = CD = \frac{1}{2}\cdot BC[/tex] (by the definition of median)
[tex]BD = CD = \frac{1}{2} \cdot (4.472)[/tex]
[tex]BD = CD = 2.236[/tex]
[tex]AD = 6[/tex]
The area of any triangle can be calculated in terms of their side length. Now, equations to determine the areas of triangles ABD and ACD are described below:
[tex]A_{ABD} = \sqrt{s_{ABD}\cdot (s_{ABD}-AB)\cdot (s_{ABD}-BD)\cdot (s_{ABD}-AD)}[/tex], where [tex]s_{ABD} = \frac{AB+BD+AD}{2}[/tex]
[tex]A_{ACD} = \sqrt{s_{ACD}\cdot (s_{ACD}-AC)\cdot (s_{ACD}-CD)\cdot (s_{ACD}-AD)}[/tex], where [tex]s_{ACD} = \frac{AC+CD+AD}{2}[/tex]
Finally,
[tex]s_{ABD} = \frac{4.123+2.236+6}{2}[/tex]
[tex]s_{ABD} = 6.180[/tex]
[tex]A_{ABD} = \sqrt{(6.180)\cdot (6.180-4.123)\cdot (6.180-2.236)\cdot (6.180-6)}[/tex]
[tex]A_{ABD} \approx 3.004[/tex]
[tex]s_{ACD} = \frac{4.123+2.236+6}{2}[/tex]
[tex]s_{ACD} = 6.180[/tex]
[tex]A_{ACD} = \sqrt{(6.180)\cdot (6.180-4.123)\cdot (6.180-2.236)\cdot (6.180-6)}[/tex]
[tex]A_{ACD} \approx 3.004[/tex]
Therefore, areas of triangles ABD and ACD are the same.

Maria has already written Ž of her 1,000 word essay. If she continues writing at the same pace of 63 words per minute, which
expression shows the amount of time it will take her to write the rest of the essay?
12
Answer:
[tex]T=\frac{1000-z}{63} \,\,\,\,or\,\,\,\,equivalently\,\,\,\,T=-\frac{1}{63} z+\frac{1000}{63}[/tex]
Step-by-step explanation:
If Maria has written already "z" words of her 1000 words essay, so the number of words she has left to do is "1000-z". Then the amount of time "T" that is left for her, is the quotient between 1000-z over 63 words/min (her writing rate).
We can then write that the time (T) it will take her to write the rest of the essay is:
[tex]T=\frac{1000-z}{63} \\T=-\frac{1}{63} z+\frac{1000}{63}[/tex]
