The function ggg models the number of mosquitoes (in millions of mosquitoes) in a certain area as a function of rainfall (in centimeters) in that area.
Answer:
6cm produces the largest mosquito
Step-by-step explanation:
The question has missing details.
From the complete question, the function is:
[tex]g(x) = 12x-x^2[/tex]
Required
Which area of rainfall produces the most mosquito
This implies that, we calculate the maximum of the function.
This is calculated as:
[tex]Max = -\frac{b}{2a}[/tex]
We have:
[tex]g(x) = 12x-x^2[/tex]
Rewrite as:
[tex]g(x) = -x^2 + 12x + 0[/tex]
From the above:
[tex]a= -1[/tex]
[tex]b = 12[/tex]
[tex]c = 0[/tex]
So, we have:
[tex]Max = -\frac{b}{2a}[/tex]
[tex]Max = -\frac{12}{2 * -1}[/tex]
[tex]Max = \frac{12}{2}[/tex]
[tex]Max = 6[/tex]
This implies that:
[tex]x = 6[/tex] ---- the maximum
When rainfall is at 6cm, there is a maximum number of mosquitoes
The maximum is then calculated as:
[tex]g(x) = 12x-x^2[/tex]
[tex]g(6) = 12 * 6 - 6^2[/tex]
[tex]g(6) = 72 - 36[/tex]
[tex]g(6) = 36[/tex]
The maximum number of mosquito is 36 million
Abby pulled marbles from a large jar, recorded the color of each marble, and then replaced the marble back into the jar. The first 8 marbles that Abby pulled are shown in the table below. If Abby plans to pull 40 more marbles, how many should she expect to be red?
a. 3 of the 40 marbles will be red
b. 10 of the 40 marbles will be red
c. 24 of the 40 marbles will be red
d. 15 of the 40 marbles will be red
Answer:
A.
Step-by-step explanation:
The results of a survey asking 500 people about their favorite ice cream flavor are shown in the table.
Find the experimental probability of each outcome in the sample space. Enter your answers in the boxes.
Flavor Number of People
Chocolate 90
Vanilla 125
Strawberry 60
Mint Chip 50
Other 175
P(chocolate) =
%
P(vanilla) =
%
P(strawberry) =
%
P(mint chip) =
%
P(other) =
%
Chocolate = 18%
Vanilla = 25%
Strawberry = 12%
Mint Chip = 10%
Other = 35%
The explanation for me getting these exact percentages is because of the formulas given for calculating the percentages from specific numbers and real world problems like this. When you are trying to find the calculation precentages of these types of questions, you divide the number by the total surveyed and multiple by 100.
Example:
125 / 500 = 0.25
0.25 x 100 = 25%
So, this is also how I got the other numbers, just change the "125" to the other numbers.
The experimental probability of each outcome in the sample space are:
P(chocolate) = 18%, P(strawberry) = 12%, P(vanilla ) = 25%, P(mint chip) = 10% and P(other) = 35%
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Flavor Number of people
chocolate 90
strawberry 60
vanilla 125
mint chip 50
other 175
So, the Experimental probability are:
P(chocolate)= 90/ 500 x 100 = 18%
P(strawberry) = 60/ 500 x 100 = 12%
P(vanilla ) = 125/ 500 x 100 = 25%
P(mint chip) = 50/ 500 x 100 = 10%
P(other) = 175/ 500 x 100 = 35%

Use the box-and-whisker plot to find the first quartile.
A trapezoid has a height of 3 meters, a base length of 8 meters, and an area of 30 square meters. What is the length of the base?
Answer:
Length of the second base will be 12 meters.
Step-by-step explanation:
Area of a trapezoid is given by the formula,
Area = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
Here, b₁ and b₂ are the bases of the trapezoid and 'h' is the vertical distance between the bases.
By substituting the values in the formula,
[tex]30=\frac{1}{2}(8+b_2)3[/tex]
[tex]60=3(8+b_2)[/tex]
[tex]20=8+b_2[/tex]
[tex]b_2=12[/tex]
Therefore, length of the second base will be 12 meters.

Step-by-step explanation:
Which statement is true about the lines 3−2=27 3 y - 2 x = 27 and 4−2=36 4 y - 2 x = 36 ?
The two lines 3 y - 2 x = 27 and 4 y - 2 x = 36 are parallel to each other because their slopes (i.e., -2/3 and -2/4) are equal.
What are parallel lines?Parallel lines are lines in a plane that do not intersect and are always the same distance apart. They have the same slope and will never meet, regardless of how far they are extended.
Therefore, the correct answer is as given above. It can be concluded that lines 3 y - 2 x = 27 and 4 y - 2 x = 36 are parallel lines to each other for their slopes (i.e., -2/3 and -2/4) are the same.

Answer:
66 baskets
Step-by-step explanation:
So, this is a simple math equation if you break it down step by step. Let's see what we know from the question.
First Day = Already 10 baskets.
Every day = +4 more baskets.
Meets her goal after 2 weeks/14 days
**Questions may use different units to try to trick you, such as weeks and days! But, they are the same.**
Okay, so now we have gathered the information we know, now lets make the math equation. First we need to make the variables. Let's let G equal how many baskets she made on day 14.
G = 10+(14x4)
G = 10+(56)
G = 66
So, she made 66 on the 14th day
What is the area of a rectangle that is 5 meters long and 8 meters wide? A. 13 m2 B. 26 m2 C.35 m2 D. 40 m2
Answer:
D. 40 m2
Step-by-step explanation:
The area of a rectangle is its length multiplied by its width.
length * width = Area
5 * 8 = 40
Answer:
[tex]\Huge\boxed{D.40m^2}[/tex]
Step-by-step explanation:
area of a rectangle = width times length
given width = 8 meters
given length = 5 meters
area = 5 * 8
8 * 5 = 40
hence, the area of the rectangle is 40m²

1. The X axis is the line going left and right
2. The Y axis is the line going up and down
3. The origin is the point where the X and Y axis meet; (0,0); by the 0
4. The points will be written as A, B, C. This is going from left to right. So the first box on the coordinate plane furthest to the left with be labeled with A. Then the second box furthest from the left; the middle box; will be labeled with B. Then the last box will be labeled C
5. (4,6)
6. (2,9)
7. (0,4)
8. When Allie identified the point, she mixed the X and Y coordinates. To identify a point you first want to find the point following the X axis. Then do the same with the Y axis. After doing this you should have 2 numbers, in which are 3 and 7. Now when writing the coordinates, the X axis ALWAYS comes first. So it should look like (7,3)
