Answer:
p=50
Step-by-step explanation:
Subtract 30 from both sides and you have your answer
Answer: 50
Step-by-step explanation:
p + 30 = 80
subtract 30 from both sides to isolate the value of "p". subtracting 30 from positive 30 cancels that out. 80 minus 30 is 50. you are left with p = 50, so the value of p is 50.
Kendrick is using a compass and straightedge to copy angle M the figure shows the portion of the construction that he has already completed where should Kendrick place the center of the compass to do the next step of the construction
Answer:
The next step of the construction is;
Place the compass at point N and adjust the width to the point where the arc crosses the other side leg of the angle
Step-by-step explanation:
The steps to copy an angle are;
1) Mark the point C of the vertex of the new angle
2) Draw a ray from C in the desired direction
3) With the compass placed at M of the original angle, draw an arc that crosses both sides of the original angle. Mark the crossing points N and O
4) With the same compass width from the arc drawn in the above step, draw a similar arc that crosses the ray from C at point D
5) Place the compass at point N and adjust the width to point O, the point where the arc crosses the other side of the angle
6) While the adjusted compass width is held to remain the same, place the compass at point D and draw an arc to cross the previous arc drawn from C and label the intersection point E
7) With the straight edge, draw a ray FC that passes through E to point C to complete the copied angle.

Find the value of z. A. 40 B. 80 C. 56 D. 62
Answer:
A
Step-by-step explanation:
The secant- tangent angle 50° is half the difference of the measures of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex](210 - x) = 50 ( multiply both sides by 2 )
210 - x = 100 ( subtract 210 from both sides )
- x = - 110 ( multiply both sides by - 1 )
x = 110°
The sum of the 3 arcs on the circle = 360°
210 + x + z = 360
210 + 110 + z = 360
320 + z = 360 ( subtract 320 from both sides )
z = 40°

Determine whether the following statement is true or false. Explain your reasoning. Jordan says that when solving the equation 4b+3=11, the best first step is to apply the Division Property of Equality.
.
A. The statement is false. Since there is a coefficient on the variable, the Multiplication Property of Equality should be used first.
.
B. The statement is true. The Division Property of Equality should always be the first property of equality used when solving linear equations.
.
C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing.
.
D. The statement is true. Since there is a coefficient on the variable, the Division Property of Equality must be used first.
Answer:
The correct option is;
C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing
Step-by-step explanation:
In other to solve the equation 4·b + 3 = 11, we have;
By the subtraction property of equality, we have;
Firstly we subtract 3 from both sides gives;
4·b + 3 - 3= 11 - 3
Next we apply the division property of equality, we have;
Both sides of an equation remain equal when we divide both sides of the equation by the same, non-number,
Dividing both sides by 4, gives;
4·b/4 = 8/4
b = 8/4 = 2
The solution to the equation, 4·b + 3 = 11 is b = 2.
what is the slope of a line that passes through the points ( 3,7) and(12,7)?
Answer:
The slope is 0.
Step-by-step explanation:
To find the slope, we can do (7 - 7) / (12 - 3) = 0 / 9 = 0. This makes sense because if we look at the points, they both have the same y-coordinate, so we know that as x increases / decreases, y never changes. Because y never changes, the slope is 0.
Answer:
m=0
Step-by-step explanation:
To find slope, it is y2-y1/x2-x1
Therefore, x1=3, x2=12, y1=7 and y2=8
Plugging those variables in,
(7-7)/(12-3)=
7-7=0
12-3=9
0/9=0
Therefore, slope of the line that passes through points (3,7) and (12,7) is 0

A group of 4 friends likes to golf together, and each friend keeps track of her all-time lowest score in a single round. Their low scores are all between 90 and 100, except for Angie, whose low score is 80. Angie then golfs a great round and has a new low score of 75. How will decreasing Angie's low score affect the mean and median?
Answer: Mean get decreased and median remains same.
Step-by-step explanation:
Given: The low scores of all 4 friends are all between 90 and 100, except for Angie, whose low score is 80.
i.e. Angie is an outlier.
[An outlier is an extreme value which lies far from the other data values.]
Angie then golfs a great round and has a new low score of 75.
i.e. more lower value.
Since Mean gets effected by an outlier but median remains same.
Here, value of new outlier(75) is less than the previous one (80), so mean score will get decreased, where as median (middle most value in ordered data) remains the same.

The graph of a linear equation is a straight line.
The graph has a positive slope and it passes through the origin
The given parameters are:
[tex]\mathbf{m =\frac 23}[/tex]
[tex]\mathbf{(x,y)= (0,0)}[/tex]
A linear equation is represented as:
[tex]\mathbf{y = mx + b}[/tex]
[tex]\mathbf{m =\frac 23}[/tex]
So, we have:
[tex]\mathbf{y = \frac 23 x + b}[/tex]
[tex]\mathbf{(x,y)= (0,0)}[/tex] represents the y-intercept (i.e. b = 0).
So, we have:
[tex]\mathbf{y = \frac 23 x + 0}[/tex]
[tex]\mathbf{y = \frac 23 x}[/tex]
See attachment for the graph of [tex]\mathbf{y = \frac 23 x}[/tex]

If sets A and B have the same number of terms, is the standard deviation of set A greater than the standard deviation of set B? 1.The range of set A is greater than the range of set B. 2. Sets A and B are both evenly spaced sets.
Step-by-step explanation:
(1) The range of set A is greater than the range of set B.
This statement gives only the range which means only outermost values but what about the other values. For example-11,0,0,0,11 and -10,-10,0,10,10
Clearly, Former one has higher range but lower standard deviation.
(2) Sets A and B are both evenly spaced sets.
Evenly spaced is fine. However, we don't know the spacing since that is required to know the deviation.
For, example, sets A{2,4,6,8,10} and B {1,2,3,4,5} so in this case SD of A> SD of B. Or, we can have B{2,4,6,8,10} and A{1,2,3,4,5} so in this case SD of B> SD of A.
