If you draw a random card from a standard deck of 52 cards, what are the odds of drawing the jack, queen, king, or ace of clubs? Write your answer in the form a:b as a fully reduced ratio. Note: In a standard deck of cards, each of the four suites has three face cards.

As per binomial distribution the probability of the following conditions are as follow:

a. probability for out of 5 none is concerned is 0.09924.

b. probability for out of 5 all are concerned is 0.02825

c. probability for out of 5 three are concerned is 0.4669.

As given in the question,

Percent of adults are concerned = 37%

p = 0.37

Percent of adults are not concerned = (100 -37)%

                                                         = 63%

1 - p = 0.63

Total number of adults 'n' = 5

Probability using binomial distribution

= ⁿCₓ pˣ ( 1- p)ⁿ⁻ˣ

a. Out of 5 none is concerned

here x = 0

⁵C₀( 0.37)⁰(0.63)⁵⁻⁰

= 0.09924

b. Out of 5 all are concerned

here x = 5

⁵C₅( 0.37)⁵(0.63)⁵⁻⁵

= 0.02825

c.  Out of 5 three are concerned

here x = 3

⁵C₃( 0.37)³(0.63)⁵⁻³

= 0.4669

Therefore , using binomial distribution the probability of the given percent of adult data is equal to as follow:

a. probability for out of 5 none is concerned is 0.09924.

b. probability for out of 5 all are concerned is 0.02825

c. probability for out of 5 three are concerned is 0.4669.

Step-by-step explanation:

Solving for y, the linear equation is: y = -4/5x - 2/5.

The table showing the corresponding y-value for each x-value is:

x |  -8  -3   2   7

y |   6   2  -2  -6

The graph is in the attachment.

To graph the linear equation of 4x + 5y = -2, rewrite in slope-intercept form by solving for y.

4x + 5y = -2

5y = -4x - 2

y = -4/5x - 2/5

Complete the table given by plugging each value of x into the linear equation, y = -4/5x - 2/5.

For x = -8:

y = -4/5(-8) - 2/5

y = 6

For x = -3:

y = -4/5(-3) - 2/5

y = 2

For x = 2:

y = -4/5(2) - 2/5

y = -2

For x = 7:

y = -4/5(7) - 2/5

y = -6

The complete table is:

x |  -8  -3   2   7

y |   6   2  -2  -6

If  hose fills a hot tub at a rate of 3.49 gallons per minute. Then 1.64 hours will it take to fill a 343​-gallon hot​ tub

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

A hose fills a hot tub at a rate of 3.49 gallons per minute.

We need to find how many  hours will it take to fill a 343​-gallon hot​ tub

3.49/1=343/x

Apply cross multiplication

x=343/3.49

x=98.28 minutes

1 hr=60 minutes

So divide 98.28/60

1.64

Hence, it takes 1.64 hours to fill the hot tub.

Step-by-step explanation:

the system of equations used to solve it is

m=4a

m-8=2a

Martie have 48 stamps and Arnav have 12 stamps.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Let Matie has x stamps and Arnav has y stamps.

Given that,

Matie has 4 times as stamps as Arnav

Implies that,

x = 4y            (1)

Also, If Matie gives 8 stamps to Arnav will have twice stamps to Arnav.

Implies that,

The equation of the line that passes through the point ((0, 3) & (3, 0) is y = -1x - 3.

What is the system of linear equations?

A system of linear equations is a group of one or more linear equations that can be solved by using a simultaneous equation or elimination method. Therefore, by using the substitution method and writing the solution of the system in terms of coordinate point (x, y) = (-1, 1).

To write the equation of a line in slope-intercept form (y = mx + b), we need to find the slope of the line (m) and the y-intercept (b).

To find the slope of the line, we can use the slope formula:

m = (y2 - y1)/(x2 - x1)

We have given the line passes through the points(0, 3) & (3, 0),

so, m = (0-3)/(3-0)

= -3/3

m = -1

The y-intercept is the point where the line intersects the y-axis. This point is (0, b), where b is the y-intercept.

Since the given line passes through the point (3, 0), we can substitute these values into the slope-intercept form of the equation to find the y-intercept:

y = mx + b

0 = -1 * 3 + b

b = -3

Solving for b gives us:

b = -3

Therefore, the equation of the line that passes through the point ((0, 3) & (3, 0) is y = -1x - 3.

The area of the paper that remains is 375.04cm².

What is an area?

The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Here,

We take it that the semicircles cover the full width of the paper.

So the radius is 16/2 = 8 cm

Since there are two of them, the area is full circle.

First, we find the area of the rectangle before the cuts were made.

Area = L * W

L = 36

W = 16

Area = 36×16 = 576 cm²

Now, we find the area of the circle cutouts.

r = 8

Area = pi * r²

Area = 3.14 * 8²

Area = 3.14 * 64

Area = 200.96cm²

Now, we find the total area left

Total Area Left = rectangle - circle

Total Area Left = 576 - 200.96

Total Area left = 375.04cm².

The equivalent form of the compound inequality is -9>-x≥-10.

A sentence having two inequality statements connected by the words "or" or "and" is referred to as a compound inequality. The conjunction "and" denotes the simultaneous truth of both statements in the compound sentence. It is when the solution sets for the various statements cross over or intersect. The conjunction "or" means that the entire compound sentence is true as long as either of the two statements is true. It consists of the union or combination of the solution sets for the various statements. A conjunction is a compound inequality that contains the word "and." Even though "and" and "or" are considered to be conjunctions of speech, their meanings in mathematics are distinct from their grammatical counterparts. The conjunction (part of speech) "or"—when used to demonstrate this point—is whenever used in a compound inequality, it creates a disjunction, as the name suggests. Simply keep in mind that "con" stands for "with another" and "dis" for "one OR the other."
