Answer:
b, a, c
Step-by-step explanation:
In a triangle, the largest angle is opposite the longest side. The smallest angle is opposite the shortest side.
This triangle has 3 given side lengths: 3 ft, 5 ft, and 7 ft.
The largest angle is opposite the longest side. That is angle b.
The smallest angle is opposite the shortest side. That is angle c.
The order from largest to smallest angle is
b, a, c

Answer:
[tex]y=2\frac{1}{7}[/tex]
Step-by-step explanation:
(y · 7) - 4 = 11
7y - 4 = 11
7y - 4 + 4 = 11 + 4
7y = 15
7y ÷ 7 = 15 ÷ 7
[tex]y=2\frac{1}{7}[/tex]

Draw and label the circle given by the equation (x - 5 + y + 10 = 6^2
Answer:
See attachment for circle
Step-by-step explanation:
Given
[tex](x -5)^2 + (y + 10)^2 = 6^2[/tex]
Required
Draw and label the circle
The equation of a circle is:
[tex](x -a)^2 + (y - b)^2 = r^2[/tex]
Where:
[tex]Center = (a,b)[/tex]
[tex]Radius = r[/tex]
So, we have:
[tex]Center = (5,-10)[/tex]
[tex]Radius = 6[/tex]

You have land that you would like to use to create two distinct fenced-in areas in the shape given below. You have 410 meters of fencing materials to use. What values of x and y would result in the maximum area that you can enclose
Answer:
[tex]x = \frac{205}{3}[/tex]
[tex]y =\frac{195}{4}[/tex]
Step-by-step explanation:
Given
[tex]p = 410[/tex] --- perimeter
See attachment for fence
Required
x and y
The perimeter of the fence is:
[tex]p = 2(x + y +5 + y) +x[/tex]
Open bracket
[tex]p = 2x + 2y +10 + 2y +x[/tex]
Collect like terms
[tex]p = 2x+x + 2y + 2y+10[/tex]
[tex]p = 3x + 4y+10[/tex]
Substitute: [tex]p = 410[/tex]
[tex]3x + 4y+10 =410[/tex]
Make 4y the subject
[tex]4y =410-10-3x[/tex]
[tex]4y =400-3x[/tex]
Make y the subject
[tex]y =\frac{400-3x}{4}[/tex]
The area (A) of the fence is:
[tex]A = (y + y + 5) * x[/tex]
[tex]A = (2y + 5) * x[/tex]
Substitute: [tex]y =\frac{400-3x}{4}[/tex]
[tex]A = (2*\frac{400-3x}{4} + 5) * x[/tex]
[tex]A = (\frac{400-3x}{2} + 5) * x[/tex]
Take LCM
[tex]A = (\frac{400-3x+10}{2}) * x[/tex]
Solve like terms
[tex]A = (\frac{410-3x}{2}) * x[/tex]
Open bracket
[tex]A = \frac{410x-3x^2}{2}[/tex]
Remove fraction
[tex]A = 205x-1.5x^2[/tex]
Differentiate both sides
[tex]A' = 205 - 3x[/tex]
To maximize; set [tex]A' =0[/tex]
[tex]205 - 3x =0[/tex]
Solve for 3x
[tex]3x = 205[/tex]
Solve for x
[tex]x = \frac{205}{3}[/tex]
Recall that: [tex]y =\frac{400-3x}{4}[/tex]
So, we have:
[tex]y =\frac{400-3*205/3}{4}[/tex]
[tex]y =\frac{400-205}{4}[/tex]
[tex]y =\frac{195}{4}[/tex]

Graph the slope Y=1/7x+1
The 1 in y = 1/7x+1, is the y-intercept. Its coordinates are (0,1). 1/7 means you are going up 1 and to the right 7, since it's positive.
On a graph, it looks like the graph above.

Answer:
Step-by-step explanation:
1). If the given triangles are similar their corresponding sides will be proportional.
[tex]\frac{8}{a}= \frac{8}{12}=\frac{5}{b}[/tex]
[tex]\frac{8}{a}= \frac{8}{12}[/tex]
[tex]a=\frac{12\times 8}{8}[/tex]
[tex]a=12[/tex]
[tex]\frac{8}{12}=\frac{5}{b}[/tex]
[tex]b=\frac{5\times 12}{8}[/tex]
[tex]b=7.5[/tex]
2). By using proportional relationship in the similar polygons,
[tex]\frac{3}{c}=\frac{6}{8}[/tex]
[tex]c=\frac{8\times 3}{6}[/tex]
[tex]c=4[/tex]
d = 8
c = e = 4
3). If the pentagons are similar their corresponding sides will be proportional.
[tex]\frac{6}{g}=\frac{8}{18}=\frac{10}{h}= \frac{8}{I}=\frac{6}{f}[/tex]
[tex]\frac{6}{g}=\frac{8}{18}[/tex]
[tex]g=\frac{18\times 6}{8}[/tex]
[tex]g=13.5[/tex]
[tex]\frac{8}{18}=\frac{10}{h}[/tex]
[tex]h=22.5[/tex]
[tex]\frac{8}{18}=\frac{6}{f}[/tex]
[tex]f=13.5[/tex]
[tex]\frac{8}{18}= \frac{8}{I}[/tex]
[tex]I=18[/tex]

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 35 hours and the median is 31.2 hours. Twenty-four of the families in the sample turned on the television for 20 hours or less for the week. The 12th percentile of the data is 20 hours. Step 1 of 5: Based on the given information, determine if the following statement is true or false. The 55th percentile is greater than or equal to 30 hours.
1: Approximately how many families are in the sample? Round your answer to the nearest integer.
2: Based on the given information, determine if the following statement is true or false. Approximately 200 families turned on their televisions for less than 35 hours.
3: What is the value of the 50th percentile?
4: Based on the given information, determine if the following statement is true or false.The first quartile is greater than or equal to 20 hours.
Answer:
Step 1: True
1. Approximately 2000 families are in the sample.
2. False.
3. 31.2 hours.
4. False.
Step-by-step explanation:
The 55th percentile is greater than or equal to 30 hours.
The median is of 31.2 hours, which means that the 50th percentile is of 31.2 hours. The 55th percentile is above the 50th percentile, and thus, the 55th percentile is greater than 31.2 hours, and thus, also greater than 30 hours, and the statement is true.
1: Approximately how many families are in the sample?
Twenty-four of the families in the sample turned on the television for 20 hours or less for the week. The 12th percentile of the data is 20 hours, and thus 24 is 12% of the sample size n. So
[tex]0.12n = 24[/tex]
[tex]n = \frac{24}{0.12}[/tex]
[tex]n = 2000[/tex]
Approximately 2000 families are in the sample.
2: Based on the given information, determine if the following statement is true or false. Approximately 200 families turned on their televisions for less than 35 hours.
The median, that is, the 50th percentile, is of 31.2 hours.
Thus, 35 hours is above the 50th percentile, which means that more than 1000 families(considerably more than 200) will have turned on their TVs for less than 35 hours, and this statement is false.
3: What is the value of the 50th percentile?
The median, which is of 31.2 hours.
4: Based on the given information, determine if the following statement is true or false.The first quartile is greater than or equal to 20 hours.
20 hours is the 12th percentile, which means that the first percentile is less than 20 hours, and this statement is false.

Write the equation of the graphed function. Give your answer in standard form.
9514 1404 393
Answer:
y = x² +x -6
Step-by-step explanation:
The graph shows the zeros of the function to be -3 and +2. This means the factored form of the function can be written as ...
y = (x -(-3))(x -(+2)) = (x+3)(x-2)
Multiplying this out, we get the desired standard form:
y = x² +x -6
We note that y=-6 when x=0, which matches the y-intercept. Nothing else needs to be done to this equation.

Answer:
Probability [Number of product more than 12] = 5 / 9
Step-by-step explanation:
Given:
Total number of products = 9
Number of product more than 12 = 5
Find;
Probability = Number of favourable outcomes / Number of total outcomes
Probability [Number of product more than 12] = Number of product more than 12 / Total number of products
Probability [Number of product more than 12] = 5 / 9
