What is the Mean Absolute Value?
Answer:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.
Step-by-step explanation:
The population of deer forest is currently 800 individuals. Scientists predict that this population will grow at a rate of 20 percent per year.
Answer:
C. 3.8 years
Step-by-step explanation:
Exponential Growth
The natural growth of some magnitudes can be modeled by the equation:
[tex]P(t)=P_o(1+r)^t[/tex]
Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
The actual population of deer in a forest is Po=800 individuals. It's been predicted the population will grow at a rate of 20% per year (r=0.2).
We have enough information to write the exponential model:
[tex]P(t)=800(1+0.2)^t[/tex]
[tex]P(t)=800(1.2)^t[/tex]
It's required to find the number of years required for the population of deers to double, that is, P = 2*Po = 1600. We need to solve for t:
[tex]800(1.2)^t=1600[/tex]
Dividing by 800:
[tex](1.2)^t=1600/800=2[/tex]
Taking logarithms:
[tex]t\log 1.2=\log 2[/tex]
Dividing by log 1.2:
[tex]t=\frac{\log 2}{ \log 1.2}[/tex]
Calculating:
t = 3.8 years
Answer: C. 3.8 years
Answer:
3.5 years

What is the slope of the line that passes through (1,2) and (8,9) ?
Answer:
slope is 1
Step-by-step explanation:
The slope formula is m=(y2-y1)/(x2-x1)
so m=[tex]\frac{9-2}{8-1}[/tex]
m=[tex]\frac{7}{7}[/tex]
m=1
so slope is 1

the table gives information about the lengths of time spent in hours, some children spent watching Tv last week
The data in the table is plotted by using a histogram as shown in the diagram attached below.
What is a histogram?
A histogram can be defined as a type of chart that is used to graphically represent a group of data points (statistical information) into user-specified ranges through the use of rectangles.
Generally, the area of each rectangle is directly proportional to the data frequency and its width is equal to the class interval.
Given the following data:
Length of time (t) Frequency.
0 ≤ t < 10 810 ≤ t < 15 1515 ≤ t < 20 1020 ≤ t < 30 11The vertical axis (y-axis) of the histogram would be used to represent the frequency density while the horizontal axis (y-axis) of the histogram would be used to represent the lengths of time spent (in hours) spent by the children in watching Tv last week as illustrated in the diagram below.

Shonda has $125. She spends 35% of the money she has on a concert ticket. How much did Shonda spend on the ticket?
Answer:
she spent $43.75
Step-by-step explanation:
you basically need 35% of $125
cool trick with this is "of" always means multiplication
35% x 125= 43.75
she spent $43.75
Shonda spent the amount of $43.75 on the concert ticket.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
To find out how much Shonda spent on the concert ticket, we can use the following proportion:
(35%) × 125 = x/1
where x is the amount of money spent on the concert ticket, and we know that 35/100 (or 0.35) is 35% of 125.
Convert percent into decimal form and solve for x:
(0.35) × 125 = x
Apply the multiplication operation, and we get
x = 43.475
Therefore, she spent $43.75 on the concert ticket.

I sell 1 piece of wood for £1000, however the price is now increased by 5000% how much will I make from 64 pieces of wood?
Answer: £3200000
Step-by-step explanation:
£1000 is 100%, so 5000% is x50 (5000/100) of £1000 which is £50000. Then 64x50000 is 3 200 000. Therefore you will make £3200000 from 64 piece of wood

You can buy 3 T-shirts for $24. Write a proportion that gives the cost c of buying 7 T-shirts. $$
Answer:
3/24 = 7/x
c = $56
Step-by-step explanation:
A percent proportion is just basically a ratio, I could also write this as 3:24 = 7:x, it really doesn't matter. What does matter is that this is considered a percent proportion. Now, to solve a percent proportion, we have this formula.
a/b = c/d
Say b is the unknown value, we would do (a*d)/c, say a was the unknown value, we would do (b*c)/d, Basically, A and D are linked together and B and C are linked together so you take the two values that are linked together first, multiply them together, and divide by the pair that has a partner that is unknown.
