Answer:
z = 68, x = 9
Step-by-step explanation:
z must equal 68 since they're vertical angles.
-----------------------------
180 - 68 = 112
12x + 4 = 112
---> x = 9
Answer:
z = 68 degrees
x = 9
Step-by-step explanation:
z = 68 degrees because of the vertex angle theorem
x is a little more complicated
First you set 68 + (12x + 4) equal to 180 becuase a straight line is 180 degrees.
68 + (12x + 4) = 180
-68 -68
12x + 4 = 112
-4 -4
12x = 108
/12 /12
x = 9

5. Find the equation of a circle whose center is at (5, -8) and radius 8.
Answer:
[tex]x^{2} + y^{2} -10x -16y + 39[/tex]
Step-by-step explanation:-
The equation used to find the equation of circle is :-
[tex](x-a)^{2} + (y-b)^{2} = radius^{2}[/tex]
'a' means the x coordinate of the circle, 'b' means y coordinate of the circle.
In the question, it's given that the coordinates of the circle are (5, -8) and radius is 8cm.
So, 'a' will be 5 and 'b' will be -8
So,
[tex](x-5)^{2} + (y--8)^{2} = 8^{2}[/tex]
[tex](x-5)^{2} + (y+8)^{2} = 64[/tex]
[tex]x^{2} - 10x + 25 + y^{2} - 16y + 64[/tex]
[tex]x^{2} + y^{2} -10x -16y + 64 - 25[/tex]
= [tex]x^{2} + y^{2} -10x -16y + 39[/tex]

Answer:
Ernesto's construction is wrong.
Step-by-step explanation:
Ernesto's construction is wrong.
This is because when bisecting an angle, the first thing we do is to place the compass at the vertex of the angle we want to bisect and draw an arc that will cross both lines that form the angle.
In Ernesto's case the arc drawn was not a single one but drawn separately as is seen in the image.
The arc on line AV does not continue to line VI but instead he drew another arc with different compass width on line VI before bisecting the angle.
a line parallel to a line that has a slope of 0 would have the slope of? geometry/algebra
Answer:
0
Step-by-step explanation:
Because
Right the slope intercept form for the line that travels through (4,-1) and is parallel to y=1/4x
Answer:
Step-by-step explanation:
The slope is given to you by the line y = 1/4 x
The slope is just read as the number in front of x providing that the coefficient of y is 1. If that is not so, then you must divide by the coefficient in front of y. So far what you have is y = 1/4 x + b.
The second part of the question is to use the given point to find b.
x = 4
y = -1
b = ? substitute x and y to find b
y = 1/4 * 4 + b
- 1 = 1/4 * 4 + b
-1 = 1 + b
-2 = b
The equation of the line is y = 1/4 x - 2 Just to confirm this, I'm going to include the graph with the point 4,-1 on it.

Answer:
x = 29
Step-by-step explanation:
All triangle angles add up to 180 so:
x + 17 + 2x + 5 + 3x - 16 = 180
6x + 6 = 180
6x = 180 - 6
6x = 174
x = 29

How do we represent a percent in a equation
Answer: heres an example
Step-by-step explanation:Convert the problem to an equation using the percentage formula: Y/X = P%
X is 60, Y is 12, so the equation is 12/60 = P%
Do the math: 12/60 = 0.20
Important! The result will always be in decimal form, not percentage form. You need to multiply the result by 100 to get the percentage.
Converting 0.20 to a percent: 0.20 * 100 = 20%
An initial investment of $3,000 earns 7% interest compounded continuously. What will the investment be worth in 19 years? (Round your answer to the nearest cent.)
Answer:
$11343.13
Step-by-step explanation:
From the given information:
Principal = 3000
rate = 7% = 0.07
time = 19 years.
The amount of investment after 19 years for a continuous compounded interest can be estimated by using the formula:
[tex]A = Pe^{rt} \\ \\ A = 3000 \times e^{0.07 \times 19} \\ \\ \mathbf{A = \$11343.13}[/tex]
The ratio of boys to girls in the school
band is 4:3. If there are 16 boys, how
many boys and girls are in the band?
A. 12
B. 28
C. 7
D. 21
Answer:
B. 28
Step-by-step explanation:
Answer:
B. 28
Step-by-step explanation:
for every 4 boys there is 3 girls
so,
from 4 to 16 you multiply by 4,
4 x 4 = 16 (what you do to one you do to the other:
4 x 3 = 12
It's asking for the total amount
if there is 16 boys there is 12 girls with the ration of 16:12
add them up,
16 + 12 = 28 (That's your answer).
Kylie surveyed seven classmates about the number of pieces of fruit they eat each week.
9, 4, 6, 2, 11, 10,7
a. What is the mean absolute deviation of the data set?
b. What does this value mean in terms of the data set?
Answer:
2.57
The mean variation in the number of pieces of fruits eaten by the classmates is 2.57
Step-by-step explanation:
Given the data:
X = 9, 4, 6, 2, 11, 10,7
The mean absolute deviation = Σ|x - xbar| / n
Xbar = mean value = Σx / n
n = sample size
The mean, xbar = (2 + 4 + 6 + 7 + 9 + 10 + 11) / 7
Xbar = 49 / 7 = 7
Take the sum of the absolute value of the difference between the mean and x ;
Σ|x - xbar| / n =
= (5 + 3 + 1 + 0 + 2 + 3 + 4) / 7
= 2.57

Step-by-step explanation:
A company says its premium mixture of nuts contains % Brazil nuts, % cashews, % almonds, and % hazelnuts, and the rest are peanuts. You buy a large can and separate the various kinds of nuts. Upon weighing them, you find there are grams of Brazil nuts, grams of cashews, grams of almonds, grams of hazelnuts, and grams of peanuts. You wonder whether your mix is significantly different from what the company advertises.
1) Explain why the chi-square goodness-of-fit test is not an appropriate way to find out.
A) The chi-square goodness-of-fit test can only be used on counts, weights are quantitative, not counts.
B) The chi-square goodness-of-fit test can only be used on quantitative variable, weights are counts, not quantitative variables.
C) The expected values are percentages, and the actual values are not. Therefore the ch-square goodness-of-fit test cannot be used.
D) The chi-square goodness-of-fit test cannot be use to test this kind of claim
2) What might you do instead of weighing the nuts in order to use a X2 test?
A) There is no way of performing a test without using weight.
B) Count the number of each kind of nut, assuming the company's percentages are based on counts rather than weights.
C) Find the volume of each kind of nut, assuming the company's percentages are based on volume.
Answer:
A) The chi-square goodness-of-fit test can only be used on counts, weights are quantitative, not counts.
B) Count the number of each kind of nut, assuming the company's percentages are based on counts rather than weights.
Step-by-step explanation:
The Test of Goodnes for fit is based on the property that the χ² test is applicable when the cell probabilities depend on unknown parameters, provided that the unknown parameters are replaced with their estimates and provided that the one degree of freedom is deducted from each parameter estimated.
1) So if the estimates ( counts) are missing the test is not applicable.
2) Percentages if treated as counts can be used for the χ² test.
ACC Algebra 1 HW
Graphing inequalities has always been a subject that I've somewhat struggled on.
Answer:
y < x
Step-by-step explanation:
equation of line can be derived by finding slope and y-intercept
in this case the slope is 1 and the y-intercept is 0
equation is y = x
however, this is an inequality so answer is one of the following:
y > x or y < x
pick a point in the shaded region (these are the 'solutions'), let's pick (1, -1)
x = 1 and y = -1
which one is true? -1 > 1 or -1 < 1
-1 < 1 is the true one so inequality is y < x
