Answer:
Step-by-step explanation:
Part A: Based on the given graph, we can observe that as the temperature of the city increases, the number of people at the swimming pool generally tends to increase as well. This suggests a positive correlation between temperature and the pool's population. In other words, when it gets hotter, more people are likely to visit the swimming pool. The relationship is not strictly linear, but it shows a general trend of increasing pool population with increasing temperature.
Part B: To determine the line of best fit, we can calculate the approximate slope and y-intercept using the given data points. Let's select two points from the data, such as (2.5, 1) and (12, 12):
Slope (m) = (change in y) / (change in x)
= (12 - 1) / (12 - 2.5)
= 11 / 9.5
≈ 1.16
To find the y-intercept (b), we can choose one of the points and substitute the values into the slope-intercept form (y = mx + b). Let's use the point (2.5, 1):
1 = 1.16 * 2.5 + b
1 = 2.9 + b
b ≈ -1.9
Therefore, the approximate slope of the line of best fit is 1.16, and the approximate y-intercept is -1.9.
Robert nixes yellow and blue paint in the ratio of three to two if he used 12 gallons of yellow paint how many gallons of blue paint would he use
Answer: 8 gallons of blue
Step-by-step explanation:
Robert mixes the paint in the ratio:
= 3 yellow : 2 blue
If there are 12 yellow used then direct proportion can be used:
3 : 2
12 : x
Cross-multiplying will give:
3x = 24
x = 24 / 3
= 8 gallons of blue

can someone help me find the area and perimeter please?
Answer:
Step-by-step explanation:
Remember that the formula to get the area of a right triangle is base times height divided by 2, so to find the area:
5 x 12 = 60/2 = 30
Area of this triangle is 30.
To find the perimeter, add all the sides:
5 + 12 + 13 = 30.
Perimeter of this triangle is 30.

Answer:
angle CDE is 10 degree
Step-by-step explanation:
As angle C is 90
Angle E is equal to angle B which is 80 (180-100)
so 90+80+X=180
X=180-170
X=10

Answer:
y=-9/2x-10
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-8)/(-2-(-4))
m=-9/(-2+4)
m=-9/2
y-y1=m(x-x1)
y-8=-9/2(x-(-4))
y-8=-9/2(x+4)
y=-9/2x-36/2+8
y=-9/2x-18+8
y=-9/2x-10

Answer:
step 1. The volume of a cylinder (V) = (pi)R^2(h).
step 2. if the volume of a similar cylinder is 88ft^3 with R =2ft
step 3. then the cylinder with R = 5 would be (5/2)^2 bigger.
step 4. the volume of figure A is 88(5/2)^2
step 5. V = 88(5/2)^2 = 550ft^3.
What is the slope of the line that contains these points? xxx -4−4minus, 4 -3−3minus, 3 -2−2minus, 2 -1−1minus, 1 yyy 222 555 888 111111
Given:
The table of values is
x y
-4 2
-3 5
-2 8
-1 11
To find:
The slope of the line that contains these points.
Solution:
From the given table consider any two point.
Let the line passes through the points (-4,2) and (-3,5). So, the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-2=\dfrac{5-2}{-3-(-4)}(x-(-4))[/tex]
[tex]y-2=\dfrac{3}{-3+4}(x+4)[/tex]
[tex]y-2=\dfrac{3}{1}(x+4)[/tex]
Using distributive property, we get
[tex]y-2=3x+12[/tex]
[tex]y=3x+12+2[/tex]
[tex]y=3x+14[/tex]
Therefore, the required equation of line is [tex]y=3x+14[/tex].

B is the midpoint of AC and AC=8r-20,and AB=3x-1
Find BC
Answer:
BC = 26
Step-by-step explanation:
since B is the midpoint of AC, then AB = BC
AC = 8x - 20 & AB = 3x - 1
AC = AB + BC or 2AB
8x - 20 = 2(3x - 1)
8x - 20 = 6x - 2
subtract 6x form each side
2x - 20 = -2
add 20 to each side
2x - 20 + 20 = -2 + 20
2x = 18
x = 9
BC = 3x - 1
BC = 27 - 1
BC = 26
AC = 52

The ratio of two number is 4:9.When 5 is subtracted from each of them,the new ratio becomes 3:8. Find the numbers.
Answer:
The numbers are 20 and 45
Step-by-step explanation:
Let the two numbers be a and b
The ratio of the two is 4:9
That means;
a/b = 4/9
9a = 4b •••••(i)
secondly;
Subtracting 5 from each gives a ratio of 3:8
(a-5)/(b-5) = 3/8
8(a-5) = 3(b-5)
8a - 40 = 3b - 15
3b - 15 + 40 = 8a
3b + 25 = 8a
a = (3b + 25)/8 •••(ii)
Insert this into 1
9(3b + 25)/8 = 4b
27b + 225 = 32b
32b - 27b = 225
5b = 225
b = 225/5
b = 45
From i;
9a = 4b
9a = 4 * 45
a = 4 * 45/9
a = 20
