an outlier in a data set can significantly affect the value of the mean but not the median. True or False

Answer:

7x + 8y ≤ 200

Step-by-step explanation:

Let's say x is the number of 550-MB disks and y is the number of 650-MB disks. Then, the cost of x 550-MB disks is 7x dollars, and the cost of y 650-MB disks is 8y dollars.

The total cost cannot exceed $200, so we have:

7x + 8y ≤ 200

This inequality represents the maximum number of disks of each type that can be bought with the budget of $200.

The area of the waxed hardwood floor is 35/9 yards square.

The formula for area is equal to the product of the length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.

Given here: Total area of the floor = 4³/₈ yards² and he waxed 8/9 part of the total area.

Now 8/9 of the total area is

Waxed area= 8/9×35/8   ( 4³/₈ =35/8)

                  =35/9

Thus the area in square units that Jahdiel waxed is 35/9 yards²

An equation which can not be used to find the value of x include the following: B. 11x + 25x = 180.

In Mathematics, a triangle can be defined as a two-dimensional (2D) geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.

Furthermore, the sum of the angles in a triangle is equal to 180. This ultimately implies that, we would sum up all of the angles as follows;

m∠D + m∠E + m∠F = 180

Substituting the given parameters into the mathematical expression, we have the following;

(11x)° + (25x)° + (9x°) = 180°

(36x)° + (9x°) = 180° or (11x)° + (34x°) = 180°

Step-by-step explanation:

Answer: 3/7

Step-by-step explanation:

The required probability for the parts which are examined for defects are ;

1. Probability of both the parts are good is equal to 0.375.

2. Probability represents exactly one part has major defect is 0.2333.

Total number of parts to be examined for defects = 16

Number of good parts = 10

Number of parts with minor defects = 4

Number of parts with major defects = 2

Number of parts to be chosen at random without replacement = 2

Total number of outcomes = ¹⁶C₂

                                             = (16!) / ( 16 - 2 )!2!

                                             = 120

1. Probability of both the parts to be good

Number of favourable outcomes = ¹⁰C₂

                                                        = 10! / (8!)(2!)

                                                        = 45

Required Probability = 45 / 120

                                   = 0.375

2. Probability of exactly one major defect

Number of favourable outcomes= ²C₁ × ¹⁴C₁

                                                      = 2 × 14

                                                      = 28

Required Probability = 28/ 120

                                   = 0.2333

Therefore, the probability of both are good is 0.375 and probability of exactly one major defect is 0.2333.

The probability of having a pile with 4 cards, another pile with 3 cards, another pile with 2 cards, and the smallest pile with 1 card is 17.36%.

The probability of a pile having 4 cards, another pile having 3 cards, another pile having 2 cards, and the smallest pile having 1 card can be calculated using the formula [tex]$\frac{n!}{n_1! n_2! n_3! n_4!}$[/tex]. In this case,

n = 10, n1 = 4, n2 = 3, n3 = 2 and n4 = 1.

Answer:

see explanation

Step-by-step explanation:

∠ 1 and ∠ 2 are corresponding angles and are congruent , then

7x - 27 = 4x + 18 ( subtract 4x from both sides )

3x - 27 = 18 ( add 27 to both sides )

3x = 45 ( divide both sides by 3 )

so

∠ 1 and ∠ 2 = 7x - 27 = 7(15) - 27 = 105 - 27 = 78°

∠ 2 and ∠ 3 are corresponding angles and are congruent , then

∠ 3 = 78°

∠ 3 and ∠ 4 are same- side interior angles and sum to 180° , that is

78 + 4y + 2 = 180

4y + 80 = 180 ( subtract 80 from both sides )

4y = 100 ( divide both sides by 4 )

y = 25

thus

∠ 4 = 4y + 2 = 4(25) + 2 = 100 + 2 = 102°

in conclusion

x = 15 , y = 25 , ∠ 1 = 78° , ∠ 4 = 102°

Answer:

w = 300 + 0.15x

Step-by-step explanation:

Let x = weekly sales

Since there is a fixed remuneration of $300, that will be a constant in the linear equation

15% = 15/100 = 0.15 in decimal

15% commission on x dollars of sales = 0.15x

Therefore total weekly pay, w, in terms of x

w = 300 + 0.15x

Approximately 68% of the area under the normal distribution curve falls within 1 standard deviation above and below the mean. This is known as the empirical rule, also called the 68-95-99.7 rule.

Approximately 95% of the area under the normal distribution curve falls within 2 standard deviations above and below the mean.

Approximately 99.7% of the area under the normal distribution curve falls within 3 standard deviations above and below the mean.

It's important to note that these values apply to a standard normal distribution (mean = 0, standard deviation = 1). For any normal distribution with a different mean and standard deviation, you can use the standard score (z-score) to transform the data into the standard normal distribution, and then use the standard normal distribution to find probabilities.

By increasing his speed to 10.4 km/h, he saves 0.175 - 0.16875 = 0.00625 hours or 0.375 minutes.

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

If a man runs at the speed of 10 km/h, it will take him 1.75 / 10 = 0.175 hours or 10.5 minutes to cover 1.75 km.

If he increases his speed to 10.4 km/h, it will take him 1.75 / 10.4 = 0.16875 hours or 10.13 minutes to cover the same distance.

So, by increasing his speed to 10.4 km/h, he saves 0.175 - 0.16875 = 0.00625 hours or 0.375 minutes.

The probability of finding between 225 and 250 orange pieces in a sample of jumbo bags is 0.7966.

The probability of finding between 225 and 250 orange pieces in a sample of jumbo bags can be written using the standard normal distribution. This is done by calculating the z-score of the interval between 225 and 250 and then calculating the probability of getting a value between the two given points.

The formula for calculating the z-score is (x-μ)/σ, where x is the value of the interval, μ is the mean (240) and σ is the standard deviation (6). The z-score of the given interval is equal to (-2.5 - (-5))/6 = 0.83.

The probability of getting a value between 225 and 250 is equal to the area under the normal curve between the two given points. This area is equal to the cumulative probability of the z-score of 0.83, which is equal to 0.7966.

Therefore, the probability of finding between 225 and 250 orange pieces in a sample of jumbo bags is 0.7966.

The experimenter's measurement of the control variable is the independent variable. Independent and dependent variables are the two different categories. These two things might be related in a cause-and-effect manner. The dependent variable is impacted by changes to the independent variable.

Dependent variables are variables that are examined or evaluated as a part of a study.Participants' test scores would be the dependent variable in a study looking at how tutoring affects test results because that is what is being measured.

Two of the most crucial terms in scientific study are "causing" and "effect. It is essential to recognise the independent and dependent variables.A "complex hypothesis" is one that describes a relationship between two or more variables. This equation, as its name implies, has a minimum of two independent variables and a minimum of two dependent variables. These illustrations can aid in your understanding of a challenging theory.
