When a fair die with faces numbered 1 to 6, the probability that the number landing face up is less than 3 is 1/3.

The probability measures how likely an event to occur. The probability of an event A is defined as:

P(A) = number of ways that event A can occur / all possible outcomes

In the given problem, let x be any number of die's face, then

number of ways x will show up = 1

all possible outcomes = 6

Hence,

P(x) = 1/6

Numbers that are less than 3 is 1 and 3. Therefore,

P (x<3) = P(1) + P(2)

P (x<3) = 1/6 + 1/6 = 2/6 = 1/3

Therefore, we can conclude that the probability that the number landing face up is less than 3 is 1/3

z >1 for the given inequality for x.

To solve the following inequality for x.

-26 + 13z + 2 > 2 132

Since there is no x in this I'm assuming we are looking for z

Step 1: Simplify both sides

15r - 26 > -13z + 2

Step 2: Add 13z to both sides

15r - 26 + 13z > -13z + 2 + 13z

28 - 26 > 2

Step 3: Add 26 on both sides

28 - 26 + 26 > 2 + 26

28z > 28

Step 4: Divide both sides by 28z / 28 > 28 / 28

z > 1

Hence the answer is z >1 for the given inequality for x.

What is simple random sampling?

Every person in the population has an equal probability of getting chosen in a simple random sampling. The entire population should be included in your sampling frame.

You might utilize instruments like random number generators or other methods that just rely on chance to carry out this kind of sampling.

Main Body:

It is uncommonly attainable to collect knowledge from each member of a gaggle of people once conducting analysis on them. In its place, you choose a sample. The population that may really participate within the study is that the sample.

The t test statistic for the bank's claim that wait times are not longer than five minutes is 4.29.

T - test statistic

T test statistic refer an inferential statistic used to determine if there is a significant difference between the means of two groups and how they are related.

Given,

Wait times for customers once they enter the bank. wait time is defined as the time between when a customer enters the bank until they reach a teller. a random sample of customers are recorded and their wait times in minutes are as follows: (4.21, 5.55, 3.02, 5.13, 4.77, 2.34, 3.54, 3.20, 4.50, 6.10, 0.38, 5.12, 6.46, 6.19, 3.79).

Here we need to determine the t test statistic for the bank's claim that wait times are not longer than five minutes.

In order to find the t test statistic, we have to calculated the average for the given waiting time,

Here the given wait times are:

(4.21, 5.55, 3.02, 5.13, 4.77, 2.34, 3.54, 3.20, 4.50, 6.10, 0.38, 5.12, 6.46, 6.19, 3.79).

In this list there are 15 members timings are presented.

Therefore, the average is calculated as,

=> (4.21 + 5.55 + 3.02 + 5.13 + 4.77 + 2.34 + 3.54 + 3.20 + 4.50 + 6.10 + 0.38 + 5.12 +  6.46 + 6.1 + 3.79) /15

Answer:

Step-by-step explanation:

Answer:

5+5=10

Step-by-step explanation:

Applying the centroid theorem, the missing measures are:

FM = 22

A.F = 66

CM = 36

ME = 18

MB = 46

DB = 69

The centroid theorem states that the distance from the centroid of the triangle to the opposite vertex is equal to one-third of the length of the segment that connects the midpoint of a side of a triangle to the opposite vertex.

Given:

AM = 44, CE = 54, and DM = 23, where M is the centroid of the triangle, thus:

FM = 1/3(FA) = 1/3(AM + FM)

Substitute

FM = 1/3(44 + FM)

3FM = 44 + FM

3FM - FM = 44

2FM = 44

FM = 44/2

FM = 22

A.F = AM + FM = 44 + 22

A.F = 66

CM = 2/3(CE)

CM = 2/3(54)

CM = 36

ME = CE - CM = 54 - 36

ME = 18

MB = 2/3(DB) = 2/3(DM + MB)

MB = 2/3(23 + MB)

3MB = 2(23 + MB)

3MB = 46 + 2MB

3MB - 2MB = 46

MB = 46

DB = DM + MB = 23 + 46

DB = 69

The option that must be true of triangle RST include:

m∠R > 90°

m∠S + m∠T < 90°

m∠R > m∠T

m∠R > m∠S

From the information illustrated in the triangle, R > S + T. It should be noted that based on the information, one angle is more than the sum of the other two angles.

Sum of angles in a triangle = 180°

If an angle is 90°, the sum of the other two angles will be 90°.

Therefore, if R = 120°, it so greater than 90°. The correct options are illustrated above.

The third degree polynomial function with zeros of −3, −1, and 4, and a y-intercept of −13 is y = -13/12 (x³ - 13x + 12)

Polynomial function:

polynomial function refers a functions of single independent variables, in which variables can occur more than once, raised to an integer power.

Given,

Third-degree, with zeros of −3, −1, and 4, and a y-intercept of −13.

Here we need to construct  a polynomial function with the stated properties and reduce all fractions to lowest terms.

The standard form for the third degree polynomial function is written as,

y = K (x + zero1) (x + zero2) (x + zero3)

Here we know the values of zeros as -3, -1 and -4.

Apply it on the general form,

y = K (x -3) (x - 1) (x + 4) ----------------------(1)

And the value of y intercept is -13 then the value of x is 0.

So, it can be written as,

-13 = K(0 - 3) (0 - 1) (0 + 4)

-13 = K (-3)(-1)(4)

-13 = K (12)

K = -13/12

Now, we have to apply these value on the equation (1), then we get,

y = -13/12 (x -3) (x - 1) (x + 4)

When we expand these, then we get the polynomial function as,

y = -13/12 (x³ - 13x + 12)

The number of red candies in the bag is 100 when the ratio of red candies to the other colors of the candies is 2:5 and the bag has 350 candies in it.

The dividend or number being divided is referred to as the antecedent, and the divisor or number that is dividing is referred to as the consequent.

A ratio compares two numbers by division. A survey of 20 respondents revealed that 13 of them preferred cake to ice cream and 7 preferred ice cream to cake.

It is given that bag of candies has several colored candies. Further, the ratio of red candies to the other colors is 2:5.

Total number of candies in the bag = 350

Number of red candies = [tex]\frac{2}{7}[/tex] × 350 = 2×50 = 100

Number of other colored candies = 350 - 100 = 250

Hence, the number of red candies in the bag is 100.

A function ix transformed when the graph of the function is translated, resized or reflected.

The formula for the transformation of a function, f(x) is y = a·f(b·(x + c)) + d

Where;

a indicates the graph of the function is dilated vertically

b  indicates a dilation horizontally

c indicates a translation horizontally

d indicates a vertical translation

The transformation applied to the parent function is the f(x) is an addition of a term, d = 3, which is a vertical translation

In a vertical translation of the form f(x) ± d

When d > 0, the graph of f(x) is moved up d units to get the graph of f(x) + d

When d < 0, the graph of f(x) is moved down d units to get f(x) - d

The graph of y = |x| + 3, obtained from the parent function, y = |x|, by a transformation of d = +3, therefore, the graph of y = |x| is moved up 3 units to get the graph of y = |x| + 3

Step-by-Step Explanation:

1, 3, 5 and 15 are the factors of 15.

After finding the ratio for each person, Ben will get $72

A ratio  shows the relative sizes of two or more values. Ratios can be shown in different ways:

It was given that Alice, Ben and Charlie are to share $213.

Ratio of Alice's share to Ben = 4 : 3

Ratio of Ben's share to Charlie = 8 : 5

Combining these ratios, their shared item (Ben's share) must be the same in each ratio.

Taking Alice's share to Ben, 4 : 3 and multiplying both parts by 8 to get an equivalent ratio, we have:

Alice : Ben = 4(8) : 3(8) = 32 : 24

Likewise, taking Ben's share to Charlie, 8 : 5 and multiplying both parts by 3, we have:

Ben : Charlie = 8(3) : 5(3) = 24 : 15

Combining these ratios, we have:

Alice : Ben : Charlie = 32 : 24 : 15

Adding the ratios together, we have: 32 + 24 + 15 = 71

If the money to be shared is $213, Ben's share will be:

[tex]\frac{24}{71}[/tex] × [tex]$213[/tex] = 72

Therefore, Ben will get $72 from the total amount of $213
