Step-by-step explanation:
Which equation is equivalent to n + 4 = 11? *
O (n +4 × 2 = 11
(n + 4) x 2 = 1112
(n+ 4) x 2 = 1184
O (n+4) x 2 = 11 * 2

Answer:
(n + 4) *2 = 11 * 2
Step-by-step explanation:
(n + 4) *2 = 11 * 2
Divide both sides by 2
[tex]\frac{(n + 4) *2}{2} = \frac{11 * 2}{2}[/tex]
n + 4 = 11

KJI = KJY + YJI
Thus ;
[tex]168 =( 8x - 4) + (36x - 4)[/tex]
[tex]168 = 8x - 4 + 36x - 4[/tex]
Collect like terms
[tex]168 = 44x - 8[/tex]
Add sides 8
[tex]168 + 8 = 44x - 8 + 8[/tex]
[tex]176 = 44x[/tex]
Divide sides by 44
[tex] \frac{176}{44} = \frac{44}{44} x \\ [/tex]
[tex] \frac{16 \times 11}{4 \times 11} = x \\ [/tex]
[tex]4 = x[/tex]
[tex]x = 4[/tex]
So ;
[tex]YJI = 36x - 4[/tex]
[tex]YJI = 36(4) - 4[/tex]
[tex]YJI = 144 - 4[/tex]
[tex]YJI = 140°[/tex]

Vertical Line Test - A function's x-values must have only 1 corresponding y-value. If the function fails this test, it is not a function.Step-by-step explanation:
When we apply the Vertical Line Test to the 1st graph, it does not pass (x = 1). Therefore, the 1st graph is not a function.
When we apply the Vertical Line Test to the 2nd graph, it does pass. Therefore, the 2nd graph is a function.
When we apply the Vertical Line Test to the 3rd graph, it does not pass (x = 2). Therefore, the 1st graph is not a function.
When we apply the Vertical Line Test to the 4th graph, it does not pass (x = -3). Therefore, the 4th graph is not a function.
Answer:
2nd graph is correct

A party-favor bag must have a volume of 140 cubic inches and the dimensions that are shown below. The equation x cubed + 6 x squared minus 27 x = 140 can be used to find x. A bag has a height of x + 9 inches, a width of x minus 3 inches, and a length of x inches. What are the dimensions of the party-favor bag? Use a graphing calculator and a system of equations to find the answer. The length is 7 inches, the width is 4 inches, and the height is 16 inches. The length is 5 inches, the width is 2 inches, and the height is 14 inches. The length is 4 inches, the width is 1 inch, and the height is 13 inches. The length is 3 inches, the width is 0 inches, and the height is 12 inches.

four added to twice a number yield 26/5. Find the number.
Answer:
3/5 is the answer
sry if it's wrong
Answer:
X=3/5
Step-by-step explanation:
Let number=X
Solution
2x+4=26/5
Cross multiply then we get
10x+20=26
10x=26-20
10x=6
X=6/10
X=3/5
So the no is 3/5
A box contains 14 large marbles and 11 small marbles. Each marble is either green or white. 8 of the large marbles are green, and 5 of the small marbles are white. If a marble is randomly selected from the box, what is the probability that it is small or green?
Answer: 19/25.
Step-by-step explanation:
Given data:
Large marbles = 14
Small marbles = 11.
8 large marbles = green.
5 of small marbles = white.
Solution:
If 8 of large marbles are green, therefore the remaining 6 are white.
Likewise for the small marbles the remaining 6 are green marbles.
Total number of marbles = 14 + 11
= 25.
P(small or green) = P(small) + P (green) – P (Both)
= 11/25 + 14/25 – 6/11
= 19/25
Answer:
Answer is 0.7536
Step-by-step explanation:
Large Marbles = 14 Small Marbles = 11
Green LM = 8 Green SM = 6
White LM = 6 White SM = 5
QUESTION:
If a marble is randomly selected from the box, what is the probability that it is small or it is green?
Note the use of "or" and not "and".
SOLUTION:
In this case, the two events - small marble & green marble - are NOT mutually exclusive. This means that sometimes they occur together. We can have a marble that is both small and green!
The formula for this probability is hence
P(A or B) = P(A) + P(B) - P(A and B)
Let A = The event that the selected marble is small
B = The event that the selected marble is green
Total number of marbles = 14 + 11 = 25
P(A or B) = 11/25 + (8+6)/25 - [P(A) × P(B)]
P(A or B) = 11/25 + 14/25 - [11/25 × 14/25]
= 0.44 + 0.56 - 0.2464 = 1 - 0.2464 = 0.7536
A salesperson makes 8% commission on everything she sells. How much money would she make if she sold $200 worth of merchandise?
Answer:
$16
Step-by-step explanation:
A sales person makes 8% on everything she sells
She sold $200 worth of merchandise
The amount of money that will be made can be calculated as follows
= 8/100 × 200
= 0.08 × 200
= $16
Hence the sales person will make $16
With 95% confidence, the researcher estimates the mean birth weight of all babies born to women who are over the age of 40 to be between 2935 and 3135 grams. The researcher wants to maintain the 95% level of confidence but report a confidence interval with a smaller margin of error. What should she do
This question is incomplete, the complete question is;
A medical researcher wants to estimate μ, the mean weight of babies born to women over the age of 40.
The researcher chooses a random sample of 100 pregnant women who are over 40. Using the mean birth weight of the 100 babies in the sample, the researcher calculates the 95% confidence interval for μ.
With 95% confidence, the researcher estimates the mean birth weight of all babies born to women who are over the age of 40 to be between 2935 and 3135 grams.
The researcher wants to maintain the 95% level of confidence but report a confidence interval with a smaller margin of error. What should she do
a) Redo the study and choose a different sample of size 100
b) Redo the study, but this time with a sample size 64
c) Redo the study, but this time with a sample 225
Answer:
Option C) is the correct answer.
C) Redo the study, but this time with a sample 225
Step-by-step explanation:
Given that;
A medical researcher wants to estimate μ, the mean weight of babies born to women over the age of 40.
n = 100
95% confidence interval is given ( 2935, 3135)
But the researcher wants to maintain the 95% level of confidence as well as smaller margin of error.
Therefore we have to reduce the margin of Error
and we know that if the sample size increases, the margin of Error decreases i.e it becomes smaller.
so the best option for the researcher is to redo the study with a larger sample size so the margin of Error becomes smaller.
Option C) is the correct answer.
c) Redo the study, but this time with a sample 225

What’s the slope of the graph? (photo included)
giving out brainliest!
Answer:
Using the slope formula with points (0,-1) and (-4,4)
Step-by-step explanation:
Step 1: find the points, (0,-1) and (-4,4)
Step 2: Insert plot points into Slope formula: (tip: M means slope)
m(slope)= [tex]\frac{y_{2} - y_{1}}{x_{2}-x_{1}}[/tex] -> m(slope)=[tex]\frac{4-(-1)}{-4-0}[/tex]
Step 3: Solve:
m(slope)=[tex]\frac{5}{-4}[/tex]
Answer:
Slope is [tex]\frac{5}{-4}[/tex]
or m = [tex]\frac{5}{-4}[/tex]
OR (if your teacher wants the answer in decimal form rounded to the nearest 10th.) m = -1.3
