The probability that an adult resident in this city regularly uses public transportation, given that he or she has the ability to drive will be 93%.

For two subsets A and B of the universal set U, we have:

[tex]\rm n(A \cup B) = n(A) + n(B) - n(A \cap B)[/tex]

A survey was given to adult residents in a particular city.

It found that 22% of the residents regularly use public transportation, and 85% of the residents have the ability to drive.

14% of the residents regularly use public transportation AND have the ability to drive.

Let P(A) be the probability of the adults that uses public transportation regularly and P(B) be the probability of the adults that has the ability to derive.

Then the probability that an adult resident in this city regularly uses public transportation, given that he or she has the ability to drive will be

n(A) = 0.22

n(B) = 0.80

n(A∪B) = 0.14

Then we have

[tex]n(A \cap B) = 0.22 + 0.85 - 0.14\\\\n(A \cap B) = 0.93\\\\n(A \cap B) = 93\%[/tex]

Answer:

Step-by-step explanation:

Usando un sistema de ecuaciones, hay que Roberto tiene $250 y Monica tiene $100.

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, las variables són:

Roberto y Mónica tienen, entre los dos, $ 350, por eso:

x + y = 350 -> y = 350 - x

La media de lo que tiene Roberto más lo de Mónica es $ 225, por eso.

0.5x + y = 225

0.5x + 350 - x = 225

0.5x = 125

x = 250

y = 350 - x = 100

Roberto tiene $250 y Monica tiene $100.

Call the pencils x, the crayons y.

4x + 3y = 20.7 inches -> 16x + 12y = 82.8 inches.

5x + 4y = 26.4 inches -> 15x + 12y = 79.2 inches.

We minus the top one from the bottom -> x = 82.8 - 79.2 = 3.6 inches

Replace back : 4 x 3.6 + 3y = 20.7
14.4 + 3y = 20.7
3y = 6.3
y = 2.1

So, the length of 1 pencil is 3.6 inches, the length of 1 crayon is 2.1 inches
Recheck : 4 pencils and 3 crayons = 3.6 x 4 + 2.1 x 3 = 14.4 + 6.3 = 20.7
5 pencils and 4 crayons = 3.6 x 5 + 2.1 x 4 = 18 + 8.4 = 26.4

The amount of money more in the account of Charlotte after 19 years than the money in account of Alyssa is, $13035.13

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

[tex]A=P\times\left(1+\dfrac{r}{n\times100}\right)^{nt}\\[/tex]

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

Charlotte invested $33,000 in an account paying an interest rate of 7 3/4% compounded continuously for 19 years. The rate of interest is,

[tex]r=7\dfrac{3}{4}\\r=\dfrac{31}{4}\\r=7.75[/tex]

Thus, the final amount in his account after 19 years is,

[tex]A=33000\times\left(1+\dfrac{7.75}{360\times100}\right)^{360(19)}\\A=143861.22[/tex]

Alyssa invested $33,000 in an account paying an interest rate of 7 1/4% compounded daily. The rate of interest is,

[tex]r=7\dfrac{1}{4}\\r=\dfrac{29}{4}\\r=7.25[/tex]

Thus, the final amount in her account after 19 years is,

[tex]A=33000\times\left(1+\dfrac{7.75}{360\times100}\right)^{360(19)}\\A=130826.09[/tex]

The more money would Charlotte have in her account than Alyssa is,

[tex]D=143861.22-130826.09\\D=13035.13[/tex]

The data of brand C suggests that brand C has the fastest clean time because it has the least average time

To do this, we simply calculate the average time of each brand.

From the complete question, we have:

Brand A: 20, 40, 60

Brand B: 30, 60, 90

Brand C: 15, 30, 45

The average is calculated using:

Average = Sum/Count

So, we have:

Brand A = (20 + 40 + 60)/3 = 40

Brand B = (30 + 60 + 90)/3 = 60

Brand C = (15 +30+ 45)/3 = 30

The least clean time is 30 (brand C).

Hence, the data of brand C suggests that brand C has the fastest clean time

Answer:

You can create geometric shapes on a coordinate plane by graphing points because when you place two points it creates a line segment and you can use the line segments to create geometric figures.

Step-by-step explanation:

I explained in the answer. I am just putting something here so my answer doesn't get deleted.

A figure can be graphed on a coordinate plane as a set of points located on specific places, specified by  their coordinates.

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Now, It is the perpendicular distance of that point from the horizontal axis and vertical axis, usually named x-axis and y-axis.

The location is then written as:

⇒ (a, b),

where 'a' is that point's shortest distance from the y-axis and called x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis, and called y-coordinate of that point.

On an infinite 2d plane, any 2-dimensional figure can be drawn.

Any figure, when drawn, the points constituting that figure can be specified using coordinates.

Thus, that figure can be graphed on a coordinate plane as a set of points located on specific places, specified by  their coordinates.

Step-by-step explanation:

Given:

Clara is stacking cups; she put 45 plastic cups in the first stack, 38 plastic cups in the second stack, 31 plastic cups in the third stack, and 24 plastic cups in the fourth stack.

To Find:

What kind of sequence is this?

Solve:

Let's make a table:

[1 stack]  45

[2 stack] 38

[3 stack] 31

[4 stack] 24

Now all we have to do is subtract to see what each is:

45 - 38 = 7

38 - 31 = 7

31 - 24 = 7

Thus,

[1 stack]  45 ⇒ 7

[2 stack] 38 ⇒ 7

[3 stack] 31 ⇒ 7

[4 stack] 24 ⇒ 7

Hence, each stack is going down by 7.

Answer:

.

Step-by-step explanation:

If the number of trials is 50. Then the probability that he will not roll a 3 on his next roll will be 0.20 or 20 %.

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as

The probability that out of n trials, there'd be x successes is given by

P(X = x) = ⁿCₓ pˣ (1 - p)ⁿ ⁻ ˣ

Sawyer conducted an experiment in which he rolled a number cube 50 times. He rolled the number 3 a total of seven times.

Then the probability that he will not roll a 3 on his next roll will be

p = 1/6 = 0.1667

q = 1 - p = 1 - 1/6 = 0.8333

Then the probability will be

P = ⁵⁰C₇ (0.8333)⁴¹ (0.1667)⁷

P = 0.20

Option D). Quadrant V is the correct answer.

Step-by-step explanation:

Your answer is correct.

Hope this helps!

Quadrant V is not the name of any of the quadrants on the coordinate plane option (D) is correct.

It is defined as a representation of coordinates in a two-dimensional

coordinate plane. It has a list of two elements in it, such as (x, y).

[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]

As we know the ordered double can be represented on the coordinate plane.

The coordinate plane has four quadrants

The name of the quadrants are:

Let (x, y), x > 0, y > 0 the point (x,y) will be on the Quadrant I

Let (x, y), x < 0, y > 0 the point (x,y) will be on the Quadrant II

Let (x, y), x < 0, y < 0 the point (x,y) will be on the Quadrant III

Let (x, y), x > 0, y < 0 the point (x,y) will be on the Quadrant IV
