Answer: 75 people
Step-by-step explanation:
1).
we have percentage of people who invested in 18-29 year category
=31%
we need
n=40 people
this is
30% of x =40
or
0.3x=40
x=40/0.3 =133.33 or 134 people
2).
in 65+ category
percentage =54%
we need
n=40
this is
54% of x =40
or
0.54x=40
or
x=40/0.54 =70.07 or 75 people

In terms of the number of moose, what is the relative frequency of male moose, female moose, adult moose, and baby moose? Write your answers as simplified fractions.
Elk Mountain Goat Deer Moose
Male 105 71 42 52
Female 120 93 63 34
Adult 173 103 72 58
Baby 52 61 33 28
The relative frequencies for the given table are:
Male → 13/44Female → 17/86Adult → 29/86Baby → 7/43How to get the relative frequencies?
The relative frequency of a given element out of a set, is given by the quotient between the number of that element and the total number of the set.
Here we can see that the total number of moose is:
52 + 34 + 58 + 28 = 172
There are 52 male moose, then the relative frequency for male moose is:
M = 52/172 = 26/86 = 13/44
There are 34 female moose, then the relative frequency is:
F = 34/172 = 17/86
There are 58 adult moose, so the relative frequency is:
A = 58/172 = 29/86
There are 28 baby moose, so the relative frequency is:
B = 28/172 = 14/86 = 7/43

Next, Chad created the graph below showing possible ratios for Pitchers cards to Infield cards in his deck. Which of the following statements are true?
On a coordinate plane, a graph titled Chad's Cards has Damage on the x-axis and Defense on the y-axis. Points (1, 2), (2, 4), (3, 6), and (4, 8) are plotted.
Chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a Catcher card.
Chad should not have included the values (1, 2) and (3, 6) because the ratio would be different for these points.
Chad should have changed the axes for the Infield and Pitchers cards so it was the same order as the table.
Chad needs to switch the order of each (x, y) value to show the decreasing values of the Pitchers cards.
The true statement for Chad graph is that:
On a coordinate plane, a graph titled Chad's Cards has Damage on the x-axis and Defense on the y-axis. Points (1, 2), (2, 4), (3, 6), and (4, 8) are plotted.What is a coordinate plane?A coordinate plane is known to be a kind of two-dimensional plane that is often created by two number lines of intersection.
Note that there is the horizontal number line known as the x-axis and the vertical number line also called the y-axis.
Looking at the question (Image attached), for every two offense, there is 4 defense.
So we can say that the proportion of offense to defense is 1:2
Therefore, the correct value or the graph is (1, 2), (2, 4), (3, 6), and (4, 8) as it doubles itself.
The true statement for Chad graph is that:
On a coordinate plane, a graph titled Chad's Cards has Damage on the x-axis and Defense on the y-axis. Points (1, 2), (2, 4), (3, 6), and (4, 8) are plotted.Therefore, option A is correct.

Two corresponding sides of two similar triangles are 3 cm and 5 cm. The area of the first triangle is 12 cm. What is the area of the second triangle?
Since the are of the first triangle is 12 cm², the area of the second triangle is 33.33 cm².
To answer the question, we need to know what similar triangles are
What are similar triangles?Similar triangles are triangles in which the ratio of their corresponding sides is constant.
Given that the corresponding sides of the two similar triangles are 3 cm and 5 cm respectively. Also, the area of the first triangle is 12 cm². We need to find the area of the second triangle.
Area of second triangleSince the triangles are similar, we have that
(side of second triangle/side of first triangle)² = Area of second triangle/Area of first triangle
Area of second triangle = (side of second triangle/side of first triangle)² × Area of first triangle
= (5 cm/3 cm)² × 12 cm²
= 25/9 × 12 cm²
= 25/3 × 4 cm²
= 100 cm²/3
= 33.33 cm²
So, the area of the second triangle is 33.33 cm².

Step-by-step explanation:
You're working with rates. It's relatively straight forward. Take miles per hour for instance. If you travel 60 miles in one hour, you're rate of speed is 60 miles per hour.
You haven't given any data in this example but the idea is the same. Let's say he transferred 10 songs in 5 minutes. That's means his rate is 10 songs per 5 minutes. You can change that to a fraction so it's easier to understand:

O$203.74
O$177.34
O$227.69
O$185.22
The amount of money that he should have at the closing of December should be $227.69.
The correct answer choice is option C
How to find total savings?Given that,
Starting amount = $24And, it plans to save 10% more as compared to the last month.
The amount of money that he should have at the closing of December can be solved using the concept of geometric sequence.
First term, a = $24
Common ratio, r = 1.10
Number of terms, n = 7
So,
Sn = a1×(r^n -1)/(r -1)
S7 = 24×(1.10^7 -1)/(1.10 -1)
= (24×0.948717) / 0.10

Step-by-step explanation:
The amounts Cory will be adding to his account comprise a geometric series with first term $24 and each successive term 10% more, or 1.10 times the previous term. The total amount Cory will have saved by the end of December is the sum of 7 terms of the series.
__
sum of geometric seriesThe sum of ...
24 +1.10×24 +1.10²×24 +... +1.10⁶×24
is given by the formula ...
Sn = a1×(r^n -1)/(r -1)
where a1 is the first term (24), and r is the common ratio (1.10).
formula applicationFor the series representing Cory's deposits, we have ...
S7 = 24×(1.10^7 -1)/(1.10 -1) = 24×0.948717/0.10 ≈ 227.69
At the end of December, Cory will have about $227.69.
