The probability that you flip 'heads' and roll a number less than 5 is 1/3.

The probability of flipping heads is 1/2, and the probability of rolling a number less than 5 is 4/6.

The probability of both occurring is the product of the two probabilities, or 1/2 multiplied by 4/6, which is equal to 1/3.

This means that the probability of flipping heads and rolling a number less than 5 is 1/3.

A sampling technique that is based on the cumulative effect of information that every additional item in the sample adds as it is inspected is called: sequential sampling.

What is sequential sampling?

Sequential sampling is a non-probability sampling strategy where the researcher selects one or more populations within a time frame, conducts his research, evaluates the findings, and then selects further populations as necessary.

An auditor develops a set of three groups of sampling units, where each successive group contains the same number of units to be sampled. The sampling plan is to continue to the next group of sampling units if the preceding group contains at least one deviation

Simple random sampling, systematic sampling, stratified sampling, and cluster sampling are examples of probability sampling techniques.

Answer:

y-intercept: (0,4)

y-intercept in the coordinate form: (0,4)

The equation in slope-intercept form: y=7x+4

Step-by-step explanation:

The slope is rise/run

We see that the y increase by 28 and the x increase by 4, so the slope is 28/4 = 7

m = 7

We know that the y-intercept is at (0,4)

So the slope-intercept equation will be

y = 7x + 4

Answer:

y- intercept = 0.4

y- intercept in the coordinate = 0.4

so the equation is : y=7x+4

Answer:

d: 7, 38/6, -1.2, -3 1/4, -19/2.

Step-by-step explanation:

First, divide the fractions to get decimals, this is an easier approach to compare all the numbers.

-19/2 = -9.5

-3 1/4 = 4 x -3 = -12 + 1 = -3.25

38/6= 6.3333 (terminal 3)

The greatest numbers for this list is 6.33, -3.25, and -9.5. The rest of the numbers include -1.2 and 7.

With the entire order, we observe which lists are descending, starting with a positive or a negative number.

1. order can be: 7, 6.33, -1.2, -3.25, and -9.5 or 7, 38/6, -1.2, -3 1/4, -19/2.

2. order commonly confused can be: -9.5, -3.25, -1.2, 6.33, and 7 or -19/2, -3 1/4, -1.2, 38/6, 7.

The only order showing this is d: 7, 38/6, -1.2, -3 1/4, -19/2.

The reason why its not the second order starting with -19/2 is because descending typically refers to a positive number going down to a negative number. However, both orders can be right. For the sake of this problem, the best option is d.

The information required for ΔTUX to be congruent with ΔDEO by Hl is the corresponding legs of the right triangle. i.e. option a. TX ≅ DO

Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal.

Congruent triangles are triangles that have the same size and shape.

Therefore, ΔTUX is congruent to ΔDEO.

Triangle can be congruent base of HL(hypotenuse and leg).

Two right triangles are congruent if the hypotenuse and one corresponding leg are equal in both triangles.

Therefore, the additional information needed to prove ΔTUX ≅ ΔDEO by HL is TX ≅ DO.

Step-by-step explanation:

First distribute the first x into the first parenthesis:  x (2x - 4) = (2x + 1) (x - 2)

x times 2x is [tex]2x^{2}[/tex] and x times -4 is -4x

This changes the equation to: [tex]2x^{2}[/tex]-4x = (2x + 1) (x - 2)

Now multiply the other parentheses: [tex]2x^{2}[/tex]-4x = (2x + 1) (x - 2)

Do this by using the Foil method (I attached a picture of the method if you don't know it)

First: (2x + 1) (x - 2)

Do 2x times x which = [tex]2x^{2}[/tex]

Then 2x times -2 which = -4x

Then 1 times x which = x

Lastly, 1 times -2 which = -2

The order you do this is the order that the foil method says.

Now the equation is:

[tex]2x^{2}[/tex]-4x =[tex]2x^{2}[/tex]-4x+x-2 (I just added all the numbers we just got)
Next cancel out the equal terms. To combine like terms you'd usually move the right [tex]2x^{2}[/tex]  over to the left one and subtract it. But since they are the same number, subtracting it would leave you with 0. So you can just get rid of both.

You can also do this with both -4x

This leaves you with:

0=x-2

Now you move the variable to the left

you also make it negative since it is going to the other side of the =

this leaves: -x=-2

You can't have a negative x so now you have to change the signs for both. Make them both positive.

Now you have x=2

so your answer is 2

The probability that detector B goes off is 0.75

In this question we have been given the security system in a house has two units that set off an alarm when motion is detected.

Here, the probability that detector A will not go off is 0.35

And the probability that A will go off and B will not go off is 0.25

We need to find the probability that B goes off

The probability that detector A will go off would be,

1 - P( detector A will not go off )

= 1 - 0.35

= 0.65

And the probability that both A and B will go off would be,

= P(A will go off) - P( A will go off and B will not go)

= 0.65 - 0.25

= 0.40

Now we find the required probability.

P(B goes off) = P(both A and B will go off) + P(detector A will not go off)

                     = 0.40 + 0.35

                     = 0.75

Viktor is in the 60th percentile, which is 85, while the percentile for 71 is 26.666.

Percentile is defined as the value below which a given percentage falls under. Ben, for instance, is the fourth tallest child in a group of 20, and eighty percent of the kids are shorter than you. As a result, Ben is in the 80th percentile.

We have the data

Sort the data as follows: 58, 64, 66, 70, 71, 75, 77, 80, 84, 85, 87, 90, 93, 95, 96

employing the percentile formula,

Percentile is calculated as follows: 71 Percentile

(4 / 15)*100 Percentile

26.666 Percentile = (Number of Values Below "x" / Total Number of Values) 100

Consequently, 71's percentile is equal to 26.666.

Identifying the rank

Thus, the ranking is 0.6.

To find the rank for viktor

Find the percentile using the formula,

Percentile = Rank × Total number of the data set

Percentile = 0.6 × 15

Percentile = 9

Now, counting 9 values from left to right we reach 85, and we can say that all the values below 85 will come under the 60th percentile. In other words, 60% of the values are below 85.

The 60th percentile is 85

Step-by-step explanation:

12c + 9a = 189

3c + 4a = 70

4c + 3a = 63

3c = 70 - 4a

c = 70/3 - 4/3 a

4(70/3 - 4/3 a) + 3a = 63

280/3 - 16/3 a + 3a = 63

(-16a + 9a)/3 = 63 - 280/3

The largest number of logically independent values—that is, values with the freedom to change—in the data sample is referred to as the degree of freedom. When calculating degrees of freedom, one is subtracted from the total number of items in the data sample.

A straightforward statistical method may be used to calculate degrees of freedom. It reads as follows: df = N-1 and indicates that degrees of freedom are equal to the number of values in a data collection minus 1. N is the number of values in the data collection, in this case (sample size).

Answer:

croissants: 10        pain au chocolat: 12

Step-by-step explanation:

85c + 95p = 2000

c + p = 22

85c + 95p = 2000    

                               -

85c + 85p = 1870

         10p = 120

           p = 12

c + p = 22

c + 12 = 22

c = 10

Answer:

Step-by-step explanation: Let C be the number of croissants and P be the number of pain au chocolat that Didier buys. We know that C + P = 22 and 0.85C + 0.95P = 20.

We can solve this system of equations using substitution. First, we solve the first equation for P: P = 22 - C. Then, we substitute this expression for P into the second equation: 0.85C + 0.95(22 - C) = 20. Expanding the expression inside the parentheses and combining like terms, we get: 0.85C + 21.1 - 0.95C = 20.

Then, we can solve for C by moving all the terms to one side of the equation: -0.1C = -1.1. Dividing both sides by -0.1, we get: C = 11.

Substituting this value for C back into the equation P = 22 - C, we get: P = 22 - 11 = 11.

Therefore, Didier buys 11 croissants and 11 pain au chocolat.
