Answer:
x = 11
Step-by-step explanation:
1. Because this is a straight angle, (11x + 7)° and (5x - 3)° add up to 180°.
[tex]11x+7+5x-3=180[/tex]2. (Solving)
Step 1: Simplify both sides of the equation.
[tex](11x+5x) + (7-3) = 180[/tex] [tex]16x + 4 = 180[/tex]Step 2: Subtract 4 from both sides.
[tex]16x + 4 - 4 = 180 - 4[/tex] [tex]16x = 176[/tex]Step 3: Divide both sides by 16.
[tex]\frac{16x}{16} = \frac{176}{16}[/tex] [tex]x = 11[/tex]Therefore, x = 11! I hope this helped you.

Answer:
In basicallity if a question such as this pops up, the correct way to go would first be to graph this. y=x-4 would be equivalent to x=4.
My paper work is below:
y = x - 4
0 = x - 4

6) 197) 22Step-by-step explanation:
Diagonals of a rectangle are congruent#6JL = KM
3x + 4 = 4x - 14x - 3x = 4 + 1x = 5JL = 3*5 + 4 = 19
#7JL = KM
2x - 6 = 3/2x + 12x - 3/2x = 1 + 61/2x = 7x = 14JL = 2*14 - 6 = 22
Answer:
JL = KM
3x + 4 = 4x - 1
4x - 3x = 4+1
X= 5
JL = 3*5 + 4 = 19
JL = KM
2x - 6 = 3/2x + 1
2x - 3/2x = 1 + 6
1/2x = 7
X= 14
JL = 2*14 - 6 = 22
For a sample size of 120 and a sample proportion of 0.4, what is the standard
error of the sampling distribution? Round your answer to three decimal
places.
A. 0.053
B. 0.064
C. 0.045
D. 0.039
Answer:
c I think not sure juinji
The standard error of the sampling distribution is 0.014. The closest option to 0.014 among the answer choices is C. 0.045, but it is not a match. None of the provided answer choices matches the calculated value exactly.
To find the standard error of the sampling distribution, we can use the formula:
[tex]Standard Error = \sqrt{[(sample proportion * (1 - sample proportion)) / sample size]}[/tex]
Given a sample size of 120 and a sample proportion of 0.4, we can calculate the standard error as follows:
[tex]Standard Error = \sqrt{[(0.4 * (1 - 0.4)) / 120]}\\Standard Error = \sqrt{[(0.4 * 0.6) / 120]}\\Standard Error = \sqrt{[0.024 / 120]}\\Standard Error = \sqrt{0.0002}\\Standard Error \approx 0.014[/tex]
Rounded to three decimal places, the standard error is approximately 0.014.

A variety pack of snacks contains 4 pretzel bags, 3 popcorn bags and 3 cheddar cracker bags. What is the probability that someone selects a pretzel bag, keeps it, and then selects another pretzel bag. HELLP PLS
Answer:
2/15
Step-by-step explanation:
Given that :
pretzel = 4
Popcorn = 3
Cheddar cracker = 3
Total = 4 + 3 + 3 = 10
Probability = Required outcome / Total possible outcomes
Selecting with replacement :
First selection :
P(pretzel bag) = 4 / 10
Second selection :
P(pretzel bag) = 3 / 9
P(2 pretzel bags) = 4/10 * 3/9 = 12 / 90 = 2/15

Answer:
A. the area of the large pond is 16 times the area of the small pond
Step-by-step explanation:
let's say 4 is the radius of the small circle, which means the area is 50.26548
if the large circle is 4 times the small circle, that means it's radius is 16 which means the area is 804.24772
so if you divide the big circle area by the small circle area:
804.24772/50.26548
it gives you 16.00000079577 which is rounded to 16
therefore, the bigger circle is 16 times bigger than the smaller circle

Which one should I choose?
Answer:
∠ 1 = 58°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
117° is an exterior angle of the triangle, then
∠ 1 + 59° = 117° ( subtract 59° from both sides )
∠ 1 = 58°

Using the formula below, calculate the z-score for the listed data points. z-score: zx = x − μ σ z1 = z5 = z6.5 =
Answer:
z1 = -1.95
z5 = 0.05
z6.5 = 0.8
Step-by-step explanation:
The value of the z score for a mean of 4 and standard deviation is 1.
What is Z score?The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ)/σ
Where x is the raw score, μ is the mean and σ is the standard deviation.
Let us assume that μ = 4, σ = 2, hence for x = 6:
z = (6 - 4) / 2 = 1
The value of the z score for a mean of 4 and standard deviation is 1.

What is the formula for the volume of a cone? (Use the word Pi instead of the symbol)
Answer:
(1/3) Pi r^2 h
Step-by-step explanation:
The volume of a cone (or pyramid, for that matter) is 1/3 the area of the base times the height.
Cones have bases that are circles, so their areas are Pi r^2, usually written [tex]\pi r^2[/tex], Pi times the radius squared.

find quotient and reminder of 4x³-12x²+15x-5÷2x-1
Answer:
The quotient is 2x² - 5x + 5, while the remainder is 0
Step-by-step explanation:
Given polynomial function;
4x³-12x²+15x-5 and a factor of 2x - 1
The quotient and remainder of the polynomial is calculated using the long division method;
2x² - 5x + 5
------------------------
2x - 1 √ 4x³-12x²+15x-5
- (4x³ - 2x²)
----------------------------
-10x² + 15x - 5
- ( -10x² + 5x)
--------------------------------
10x - 5
- (10x - 5)
-----------------------------------------
0
Therefore, the quotient is 2x² - 5x + 5, while the remainder is 0.
A café has a monthly fixed cost of $4700, and a typical customer order costs the café $2. Therefore, the cost to serve x customers in a month is given by x = 4,700 + 2x. The typical order costs $10. So revenue is y = 10x. Find the number of customers that would need to come in the café for the company to break even. (Intersection point)
Answer:
The number of customers that would need to come in the café for the company to break even is 470.
Step-by-step explanation:
Given
Revenue = y = 10x ……………….…. (1)
Cost = x = 4,700 + 2x ……………… (2)
Since the company will break even when Revenue is equal to Cost, we therefore equate equations (1) and (2) and then solve for x as follows:
10x = 4,700 + 2x
10x - 2x = 4,700
x = 4,700 / 10
x = 470
Therefore, the number of customers that would need to come in the café for the company to break even is 470.
Distribute then combine like terms in the following: 2(2x - 3y) - 3(x - 2y - 4) 4

4x-6y-3x-24y
