Answer:

49 or 1

Step-by-step explanation:

answer 1 14+10+13+12=49 answer 2 (14+10)-(13+12)=1

Answer:

Consider one of eight positions separately from all others. There are 10 possible ways to choose

a digit to place on this position since there are ten digits from 0 to 9, and this choice is

independent of all other positions since each digit can be repeated and there is no restriction on

how to choose digits.

So, we have 8 positions and each one is filled by a digit in 10 ways independently from each other,

therefore the total number of possible codes equals to ways it can be done for each independent

position multiplied altogether. This is 10 × 10 × … × 10 = 108

(100 million).

Answer: 108 different codes.

a. Amount of time spent shopping for clothing in the past week = CONTINUOUS NUMERICAL

b. Preferred brand of shoes = CATEGORICAL

c. Number of deliveries received at the household per week = DISCRETE NUMERICAL

d. Most likely time period during which shopping for clothing takes place (weekday, weeknight, or weekend) = CATEGORICAL

Step-by-step explanation:

Determine whether variable is Categorical or Numerical (Discrete or continuous) :

Categorical variables are used in grouping data values into a defined set of classes or distinct groups. Numerical variables are those usually represented with numbers and this posses numerical meaning. Numerical variables can either be discrete when the values in the dataset are finite or continuous, when values aren't finite and usually uncountable.

a. Amount of time spent shopping for clothing in the past week = CONTINUOUS NUMERICAL

b. Preferred brand of shoes = CATEGORICAL

c. Number of deliveries received at the household per week = DISCRETE NUMERICAL

d. Most likely time period during which shopping for clothing takes place (weekday, weeknight, or weekend) = CATEGORICAL

Categorical Variables : b) Preferred shoe brand; & d) Likely period of shopping

Numerical Continuous Variable : a) Amount of shopping time ; & Numerical Discrete Variable : c) Number of deliveries

Numerical Variables, as the name denotes - can be expressed in numbers. Like : Number of variable x.

Categorical Variables, as the name denotes - cant be expressed n numbers but rather in categories. Like : A person being man, woman or other gender.

A] Amount of time spent shopping for clothing in the past week : Numerical & Continuous, can be in decimal values like 2.8 , 4.5 hours etc

B] Preferred brand of shoes : Categorical Variable, will be amongst the brand names like Pima, Nuke etc

C] Number of deliveries received at the household per week : Numerical & Discrete , can be only in non decimal whole values - like 4 , 5 , 10 etc

D] Most likely time period during which shopping for clothing takes place : Categorical Variable, will be amongst the mentioned period of weeks or days - like weekday, weeknight, or weekend

Step-by-step explanation:

Kahn Academy

The given lines are intersecting but not perpendicular.

In Euclidean geometry, the empty set, a point, or another line can intersect another line. For instance, computer graphics, motion planning, and collision detection can all benefit from differentiating these cases and locating the intersection.

Given:

        y = 6x - 2

2x - 12y = 24

⇒  6x - y = 2         ..(1)

2x - 12y = 24       ..(2)

Multiply second equation by 3,

6x - 36y = 72           ..(3)

Subtract equation (1) from equation (3).

    6x - 12y = 24

-    6x -    y  = 2

_______________

         -11y = 22

   y = -2

Plug y = -2 in equation (1)

6x - (-2) = 2

6x + 2 = 2

      6x = 2 - 2

      6x = 0

        x = 0

The solution of the given system is (0, -2).

Hence, the given lines are intersecting but not perpendicular.

Step-by-step explanation:

There are a total of N = 25 aluminum castings.

Of these 25 aluminum castings, n₁ = 4 castings are defective (D) and n₂ = 21 are good (G).

It is provided that a quality control inspector randomly selects three of the twenty-five castings without replacement to test.

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

[tex]{n\choose k}=\frac{n!}{k!(n-k)!}[/tex]

Compute the number of samples that are possible as follows:

[tex]{25\choose 3}=\frac{25!}{3!\times (25-3)!}[/tex]

      [tex]=\frac{25\times 24\times 23\times 22!}{3!\times 22!}\\\\=\frac{25\times 24\times 23}{3\times 2\times 1}\\\\=2300[/tex]

Step-by-step explanation:

The equation of the perpendicular line is y = -1/2x + 3. The correct option is (B).

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

The coordinates of the given points are (-2, 0) and (0, 4).

The equation of the line for the given points can be written as follows,

(y - 4)/(x - 0) = (4 - 0)/(0 - (-2))

=> y - 4 = 2x

=> y = 2x + 4

Comparing the above equation with the general equation y = mx + c the  slope is given as,

m = 2

Now, the product of the slopes of two perpendicular lines is -1.

Thus, the slope of the perpendicular line is,

m' = -1/2.

In order to find the the correct answer compare all the options with general equation y = mx + c and check if the slope is -1/2 as below,

(a) y = 1/2x - 2

m = 1/2

(b) y = -1/2x + 3

m = -1/2

(c) y = 2x + 1

m = 2

(d) y = -2x + 4

m = -2

Hence, the equation for the line perpendicular to the given line is  y = -1/2x + 3.

Answer:

Please find the correct placement in a tabular format in the attached image. The explanation has been done below.

Step-by-step explanation:

The process of photosynthesis occurs in two stages viz: light-dependent and light-independent reactions.

- In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.

- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.

Answer:

a) 15.866%

b) Middle 95% = 350 ml to 750 ml

c) 0.3829

d) Middle 90% of men’s bladder fall = 385.5ml to 714.5 ml

Step-by-step explanation:

We solve using z score formula

z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

The distribution of bladder volume in men is approximately Normal with mean 550 ml and standard deviation 100 ml.

Required:

a. What percent of men have a bladder volume smaller than 450 ml?

z = 450 - 550/100

= -1

P-value from Z-Table:

P(x<450) = 0.15866

Convert to percentage

0.15866 × 100

= 15.866%

b. Between what volumes do the middle 95% of men’s bladders fall?

Middle 95% falls between 2 standard deviation of the mean

μ ± 2σ

μ - 2σ

550 - 2(100)

= 550 - 200

= 350 ml

μ + 2σ

= 550 + 2(100)

= 550 + 200

= 750 ml

Middle 95% = 350 ml to 750 ml

c. What proportion of male bladders are between 500 and 600 ml?

For 500ml

z = 500 - 550/100

= -0.5

Probability value from Z-Table:

P(x = 500) = 0.30854

For 600ml

z = 600 - 550/100

= 0.5

Probabilty value from Z-Table:

P(x = 600) = 0.69146

Proportion of male bladders are between 500 and 600 ml

P(x = 600) - P(x = 500)

0.69146 - 0.30854

= 0.38292

≈ 0.3829

d. What volumes do the middle 90% of men’s bladder fall?

The z score for middle 90% + / – 1.645

Hence,

1.645 = x - 550/100

1.645 × 100 = x - 550

164.5 + 550 = x

x = 714.5 ml

-1.645 = x - 550/100

-1.645 × 100 = x - 550

- 164.5 + 550 = x

x = 385.5ml

Middle 90% of men’s bladder fall = 385.5ml to 714.5 ml

Answer:

The domain of [tex]f(x)[/tex] is restricted to [tex]x\leq 0[/tex], and the domain of [tex]f^{-1}(x)[/tex] is restricted to [tex]x\geq 4[/tex].

Step-by-step explanation:

From Function Theory we know that domain of a function is the set of values such that an image exist. Let [tex]f(x) = x^{2}+4[/tex] and [tex]f^{-1}(x) = \sqrt{x-4}[/tex] the function and its inverse, respectively.

At first glance we notice that function is a second order polynomial and every polinomial is a continuous function and therefore, there exists an image for every element of domain.

But domain of its inverse is restricted to every value of x so that [tex]x-4 \geq 0[/tex], which means that [tex]x\geq 4[/tex].

Finally, we concluded that following answer offers the best approximation to our result:

The domain of [tex]f(x)[/tex] is restricted to [tex]x\leq 0[/tex], and the domain of [tex]f^{-1}(x)[/tex] is restricted to [tex]x\geq 4[/tex].
