Rectangle

Interior angles are all 90°

5x - 3° = 90° 5x = 93° x = 93°/5 x = 18.6° (28)

Rhombus

All sides are congruent

14 - x = 2x + 5 2x + x = 14 - 5 3x = 9 x = 3 (29)

Square

Diagonals are perpendicular

13x + 5.5° = 90° 13x = 84.5° x = 84.5°/13 x = 6.5°

For a sample size of 120 and a sample proportion of 0.4, what is the standard

places.

B. 0.064
C. 0.045
D. 0.039

Answers

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.

Step-by-step explanation:

Diagonals of a rectangle are congruent#6

JL = KM

3x + 4 = 4x - 14x - 3x = 4 + 1x = 5

JL = 3*5 + 4 = 19

#7

JL = KM

2x - 6 = 3/2x + 12x - 3/2x = 1 + 61/2x = 7x = 14

JL = 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

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

Answers

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

Using the formula below, calculate the z-score for the listed data points. z-score: zx = x − μ σ z1 = z5 = z6.5 =

Answers

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.

find quotient and reminder of 4x³-12x²+15x-5÷2x-1​

Answers

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.

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

Step-by-step explanation:

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)

Answers

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.
