25-[20-{10-(7-5-3)}]=
Answer:
16
Step-by-step explanation:
When there are more than 1 brackets , there is a specific order of opening those brackets. First we open the bar , then round brackets , then curly brackets & then square brackets.
Using the order , let's solve this.
25-[20-{10-(7-5-3)}]
=> 25-[20-{10-(7 - 8)}]
=> 25-[20-{10 - (-1)}]
=> 25-[20- {10 + 1} ]
=> 25-[20 - {11}]
=> 25 - [ 20 - 11 ]
=> 25 - [9]
=> 25 - 9
=> 16

Consider the intersecting lines shown. Which of the following statements is true?
Question 10 options:
A)
∠y ≅ ∠z
B)
∠x ≅ ∠y
C)
m∠x + m∠y = 180°
D)
m∠x + m∠y = 90°
Answer:
C. m∠x + m∠y = 180
Step-by-step explanation:
The two straight line in the diagram intersect each other to form two pairs of vertical angles. These are <x and <z, and <y and w.
The only statement from the given options that is true is m∠x + m∠y = 180.
This is because they are angles in a straight line. The sun of angles in a straight line is 180°.

Answer:
slope = 4/1 or 4
Step-by-step explanation:
Answer: 4
Step-by-step explanation:
Use the slope formula. change in y/change in x. The change in y is 4 because if your subtract the y coordinate 4 from the y coordinate 8, you get 4. The change in x is 1 because if you subtract the x coordinate 2 from the x coordinate 3, you get 1. 4 (change in y)/1 (change in x) is 4. Hope this helps!

Your answer:
N
11.12
13.78
15.6
14.32
Answer:
D. 14.32
Step-by-step explanation:
The formula for standard deviation is:
[tex]SD = \sqrt{\frac{\sum | x-\mu|^2}{N}}[/tex]
The mean μ is 33.
The (x minus μ) squared are 361, 49, 49, 361 respectively.
So that the SD = [tex]\sqrt{\frac{820}{4}} \approx 14.31782...[/tex]

The weight of body is 420N. calculate its mass.
Answer:
mass = 42 kg
Step-by-step explanation:
We know that we have the formula that
W = m * g
Then
given
weight (w) = 420
g = 10 m/s²
then
W = m* g
420 = m * 10
m = 420/10
m = 42 kg
Hope it helps :)
Answer:
Step-by-step explanation: weight = 420N
mass= ?
we know,
weight = mass . acceleration due to gravity
or, 420 = mass . 9.8
therefore mass = 42.85 kg

Rachel drew the two graphs below. Graph R On a coordinate plane, a line goes through points (0, 0) and (2, 1). Graph S On a coordinate plane, a line goes through points (0, 0) and (1, 2). Rachel says that Graph R has a greater constant of variation than Graph S. Which statement explains whether Rachel is correct? Rachel is correct; Graph S is nonproportional. Rachel is correct; Graph R goes farther along the x-axis. Rachel is not correct; both graphs go through the origin and have the same constant of variation. Rachel is not correct; Graph S is steeper than Graph R.

Determine any data values that are missing from the table, assuming that the data represent a linear function.
X Ix ly |-12 17 -10 19 -8 23
a. Missing x:-6 Missing y:22
b. Missing x:-7 Missing y:22
c. Missing x:-7 Missing y:20
d. Missing x:-6 Missing y:21
Please select the best answer from the choices provided Save and Exit Next Submit Mark this and return
Answer:
we conclude that:
The value of missing x = 6The value of missing y = 21Step-by-step explanation:
Given that the table represents a linear function, so the function is a straight line.
Taking two points
(-12, 17)(-10, 19)Finding the slope between (-12, 17) and (-10, 19)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-12,\:17\right),\:\left(x_2,\:y_2\right)=\left(-10,\:19\right)[/tex]
[tex]m=\frac{19-17}{-10-\left(-12\right)}[/tex]
[tex]m=1[/tex]
Using the point-slope form to determine the linear equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 1 and the point (-12, 17)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 17 = 1 (x - (-12)[/tex]
[tex]y - 17 = x+12[/tex]
[tex]y = x + 12+17[/tex]
[tex]y = x+29[/tex]
Thus, the equation of the linear equation is:
[tex]y = x+29[/tex]
Now substituting x = -8 in the equation
[tex]y = x+29[/tex]
[tex]y = -8+29[/tex]
[tex]y = 21[/tex]
Thus, the value of missing y = 21 when x = -8
Now substituting y = 23 in the equation
[tex]y = x+29[/tex]
[tex]23 = x+29[/tex]
[tex]x = 29 - 23[/tex]
[tex]x = 6[/tex]
Therefore, the value of missing x = 6 when y = 23
Hence, we conclude that:
The value of missing x = 6The value of missing y = 21Answer:

so then it's 12-1 which is 11
5m-4=5*3-4
15-4 thats 11
wait ok so
11=11
Answer:
=Step-by-step explanation:
m = 3
4m - 1 = 4(3) - 1 = 12 - 1 = 11
5m - 4 = 5(3) - 4 = 15 - 4 = 11

a. Venn diagram
b. side-by-side bar chart
c. bar chart
d. tree diagram
Answer:
d. tree diagram
Step-by-step explanation:
Given that a Tree diagram is a technique or method used in the mathematical or statistical theory of probability to determine the result of a particular event under investigation. The targeted result will be gotten at the end of each branch in the tree diagram.
To determine the targeted result of the occurring events, the branches of the tree diagram are multiplied.
