Answer:36

Step-by-step explanation:

Three people get into an empty elevator at the first floor of a building that has floors. Therefore the probability that the buttons for consecutive floors are pressed is 1/2 x 1 = 1/2 or 0.5.

To simplify the problem we can see that there are three persons and all of them have their desired floors. Each one of them has pressed the button for their floor.

We can construct a number line to represent the floors. Let us suppose that the number line represents the floors of a 10 story building.

Number line: ... 7 8 9 10 [first person] [second person] [third person]

Let us see the scenario where the buttons for consecutive floors are pressed. Let the first person press the button for the 3rd floor. Then the second person could press the button for either the 2nd floor or the 4th floor.

We can only have the buttons for consecutive floors pressed if the second person presses the button for the 2nd floor

The probability of this happening. There are only 2 possibilities for the second person to press the button:

Press the button for the 2nd floor.

Press the button for the 4th floor.

Both of these possibilities are equally likely.

Therefore the probability that the second person will press the button for the 2nd floor is 1/2.The third person has only one choice. They can only press the button for the 4th floor.

Therefore the probability that the buttons for consecutive floors are pressed is 1/2 x 1 = 1/2 or 0.5.

The solution:

Given:

cosine function has an amplitude of 4, a vertical shift of 1, and a period of 3.

Required:

To write out the equation of the graph in terms of cosine.

So, the required equation is:

Therefore, the correct answer is:

The slope and y-intercept of 3x - 2y = 5 is 3/2 and -5/2 respectively.

In the given question, we have to find the slope and y-intercept of 3x-2y=5.

The general equation of line is y = mx + c, where m is the slope of line and c is the y-intercept of line.

The given equation of line is 3x - 2y = 5.

To find the slope and y-intercept we first isolate the y.

Subtract 5 on both side, we get

3x - 2y - 5 = 0

Add 2y on both side, we get

2y = 3x - 5

Divide by 2 on both side, we get

y = \(\frac{3}{2}x-\frac{5}{2}\)

On comparing the equation by y = mx + c, we get

m = 3/2 and c = -5/2

Hence, the slope and y-intercept of 3x - 2y = 5 is 3/2 and -5/2 respectively.

A 95% confidence interval for the fraction of fortune 500 ceos who believe Indiana university(IU) deserves its ranking is ( 0.279, 0.361)

According to the question,

Total number of sample taken for questionnaire = 500

Number of people responded = 160

Sample Proportion : p = 160/500

=> p = 0.32

Proportion of people who has not responded : q = 1 - p

=> q = 0.68

We have to create a 95% confidence interval for the fraction of fortune 500 ceos who believe Indiana university(IU) deserves its ranking.

Formula of C.I = p ± z√pq/n

Where p and q is sample proportion , z is value of CI at given α level of significance and n is sample size

C.I at 95% = 0.32 ± 1.96√0.32×0.68/500

=> 0.32 ± 1.96 √0.0004352

=> 0.32 ± 1.96 × 0.0208

=> 0.32 ± 0.0408

C.I = ( 0.32 - 0.0408,  0.32 + 0.0408)

=> C.I = ( 0.279, 0.361)

Answer:

The maximum volume the cube could have is 729 cubic inches

Step-by-step explanation:

The total surface area of the cube equals the total area of material used.

Let A = total surface area of cube = 6L² where L = length of side of cube

Since A = total area of material used, A = 486 in²

So 486 in² = 6L²

L = √(486 in²/6)

= √81 in²

= 9 in

The volume of the cube V = L³ where L = length of side of cube

So, V = (9 in)³

= 729 in³

So the maximum volume the cube could have is 729 cubic inches.

The maximum volume that the box could have will be 729inches³.

Based on the information given, the first thing to do is to find the length of the shape. This will be:

Length = ✓(486/6)

Length = ✓81

Length = 9

Therefore, the volume of the cube will be:

= 9³

= 9 × 9 × 9

= 729 in³.

Step-by-step explanation:

Sorry if it’s wrong

In a time series design, a researcher collects data on a dependent variable (DV) at multiple time points before and after the implementation of a treatment. If the researcher notes that every time sampled individuals are observed on the DV, the average score increases, it may be tempting to attribute this variation to the treatment.

However, caution should be exercised when making such conclusions. While the observed trend in the DV may be associated with the treatment, it's essential to consider alternative explanations, such as maturation, history, or regression to the mean. Maturation refers to the natural developmental processes that occur in participants over time, which might contribute to the observed changes. History refers to external events that could impact the DV, unrelated to the treatment. Regression to the mean occurs when extreme scores naturally become closer to the average over time, which might be mistaken as a treatment effect.

To confidently attribute variation in the DV to the treatment, the researcher should consider using a control group and a comparison group design. This allows for the comparison of changes in the DV between those who received the treatment and those who did not, reducing the likelihood of confounding variables.

In summary, although the increasing average scores in a time series design may suggest a relationship between the treatment and the DV, the researcher should be cautious when attributing this variation solely to the treatment. Other factors and potential confounding variables must be considered before making any definitive conclusions.

Answer:

\(\Huge \fbox{72 mph}\)

Step-by-step explanation:

Step 1:

Convert \(\bold{32 m/s}\) to \(\bold{km/h}\) by multiplying by 3.6 (since \(\bold{1 m/s}\) = \(\bold{3.6 km/h}\))

\(\large \text{32 m/s $\times$ 3.6 = 115.2 km/h}\)

Step 2:

Convert \(\bold{115.2 km/h}\) to \(\bold{mph}\) using the given conversion factor of \(\bold{8 km/h = 5 mph}\)

\(\large \text{115.2 km/h $\div$ 8 km/h = 14.4}\\\text{14.4 $\times$ 5 mph = 72 mph}\)

Therefore, \(\bold{32 m/s}\) is equivalent to \(\bold{72 mph}\).

----------------------------------------------------------------------------------------------------------

In the standard conversion unit, 32 m/s equals 72 mph in mph

The conversion equation is given as

\(\sf 8 \ km/h = 5 \ mph\)

Convert 8 km to meters

So, we have the following equation

\(\sf 8 \times 1000 \ m/h = 5 \ mph\)

Evaluate the products

So, we have the following equation

\(\sf 8000 \ m/h = 5 \ mph\)

Convert 1 hour to seconds

So, we have the following equation

\(\sf 8000 \ m/3600 s = 5\ mph\)

Evaluate the quotient

So, we have the following equation

\(\sf \dfrac{20}{9} \ m/s = 5 \ mph\)

Multiply both sides by 9/20

\(\sf 1 \ m/s = \dfrac{9}{20} \times 5 \ mph\)

Multiply both sides by 32

\(\sf 32 \times 1 \ m/s = 32 \times \dfrac{9}{20} \times 5 \ mph\)

Evaluate the products

\(\sf 32 \ m/s = 72 \ mph\)

Hence, the equivalent of 32 m/s in mph is 72 mph

If Tamika adds two separate numbers at random from the collection, the likelihood that her result will be higher than Carlos' result is 4/9. To multiply two random integers from the set, Carlos chooses two more random numbers.

This event has a chance of happening or not happening.

calculation

Tamika might receive any of the following results, all of which are equally likely:

8+9=17 

8+10=18

9+10=19

The various potential values that Carlos could receive—all equally likely—are:

3 * 5=15

3 * 6=18

5 * 6=30

Because 17 is only greater than 15, the likelihood that Tamika's total would be greater than Carlos's set is 1/3.

Because 18 is only greater than 15, the likelihood that Tamika's total would be greater than Carlos's set is 1/3.

Due to the fact that 19 is greater than both 15 and 18, the likelihood that Tamika's total would be greater than Carlos's set is 2/3.

We have 1/3(1/3+1/3+2/3)=1/3(4/3)=4/9 since each sum has a 1/3 chance of being chosen.

the likelihood of the difference between Tamika's performance and Carlos' performance is 4/9.

The distance from the midpoint of AB to the midpoint of AC is equal to: D. √37.

In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and then divide by two (2):

Midpoint = [(x₁ + x₂)/2, (y₁ + y₂)/2]

For line segment AB, we have:

Midpoint of AB = [(-6 - 8)/2, (6 - 2)/2]

Midpoint of AB = [-14/2, 4/2]

Midpoint of AB = [-7, 2].

For line segment AC, we have:

Midpoint of AC = [(-6 + 4)/2, (-4 + 6)/2]

Midpoint of AC = [-2/2, 2/2]

Midpoint of AC = [-1, 1].

In Mathematics and Geometry, the distance between two (2) endpoints that are on a coordinate plane can be calculated by using the following mathematical equation (formula):

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance = √[(-1 + 7)² + (1 - 2)²]
