and dang stop crying... hope this helped
I WILL GIVE BRAINLIEST
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!
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

What is the standard deviation of the following data set?
{14, 26, 40,52}
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]

m=3
4m-1=4*3-1
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
4m - 1 = 5m - 4

Two sides of a triangle are equal in length. The third side of the triangle is 3 more than the equal sides. If the perimeter of the triangle is 48, what is the length of the longest side?
Show work
Answer:
18
Step-by-step explanation:
The two smaller sides are 15 and the larger one is 18
Answer:
18Step-by-step explanation:
Let the length of equal sides be x, then the perimeter is:
2x + (x + 3) = 483x + 3 = 483x = 45x = 15The longest side is:
15 + 3 = 18

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:

1. Fill in the missing numbers in these equations

A display that helps us think through calculations with conditional probabilities and the general multiplication rule is a:________
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.
Hence, a display that helps us think through calculations with conditional probabilities and the general multiplication rule is a TREE DIAGRAM

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

If the 4th and 7th terms of a G.P are −1/2 and
− 4, respectively, then find G5 and S6 .
Answer:
G5 = -1
S6 = -63/16
Step-by-step explanation:
The formula for finding the nth term of a GP is Tn = ar^n-1
a is the first term
r is the common ratio
n is the number of terms
If the 4th term is -1/2
T4 = ar^4-1
T4 = ar³ = -1/2.... 1
If the 7th term is -4
T7 = ar^7-1
T7 = ar^6 = -4.... 2
Divide both equation
ar^6/ar³ = -4/(-1/2)
r³ = -4×-2
r³ = 8
r = 2
Common ratio is 2
Since ar³ = -1/2
a(2)³ = -1/2
8a = -1/2
a = -1/16
The first term is -1/16
Get the fifth term G5
G5 = ar⁴
G5 = (-1/16)(2)⁴
G5 = (-1/16)(16)
G5 = -1
Get the sum of the first six terms S6
S6 = a(r^n-1)/r-1
S6 = -1/16(2^6-1)/2-1
S6 = -1/16(64-1)
S6 = -63/16
Hence the sum of the first six terms is -63/16

For a random sample of Harvard University psychology majors, the responses on political ideology had a mean of 3.18 and standard deviation of 1.72 for 51 nonvegetarian students and a mean of 2.22 and standard deviation of .67 for the 20 vegetarian students. When we use software to compare the means with a significance test, we obtain the following printout.Variances T DF Prob>|T|Unequal 2.9146 41.9 0.006Interpret the P-value, in context, based on its definition.
Answer:
From the test give in the question it is obvious that there is enough evidence to show that population mean varies for vegetarian and non-vegetarian
The P-value helps affirm the null hypothesis claims,The P-value attains values relatively as large as that which exists in the sample given,if the null hypothesis is right
Step-by-step explanation:
From the question we are told that
Sample mean [tex]\=x_1=3.18[/tex]
Standard deviation [tex]\delta_! =1.72[/tex]
Sample size [tex]n_1 =51[/tex]
Sample mean [tex]\=x_2=2.22[/tex]
Standard deviation [tex]\delta_2 =0.67[/tex]
Sample size [tex]n_2=20[/tex]
Generally this is a two tailed test
therefore
Null hypothesis = [tex]h_0 :P_v_e_g= P_n_o_n_v_e_g[/tex]
Alternative hypothesis [tex]H_a : P_v_e_g \neq P_n_o_n_v_e_g[/tex]
From the test give in the question it is obvious that there is enough evidence to show that population mean varies for vegetarian and non-vegetarian
The P-value helps affirm the null hypothesis claims,The P-value attains values relatively as large as that which exists in the sample given,if the null hypothesis is right

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.
