Answer:

Fair dice mean that each of the faces has the same probability of landing facing up. A standard 6-sided die, for example, can be considered “fair” when each of the faces has the same probability of ⅙.

Step-by-step explanation:

As per the unitary method, the linear equation represents the number of minutes Denzel still has to practice is N(x) = 210 - 30x

The term unitary method refers a process of finding the value of a single unit, and based on this value.

Here we have given that Denzel must practice the piano for 210 min each week. he practices for 30 min each day

And we need to find linear equation represent the number of minutes Denzel still has to practice after x days

As from the given question we know that Denzel must practice piano for 210 minutes each week.

Therefore, the total practice needed = 210 minutes

And the total minutes practicing per day = 30 minutes

Here let us consider x be the number of days practiced

Then the total minutes practices after n days = 30x

So, the total remaining minutes is calculated as,

=> 210 - 30x

Therefore, the number of minutes Denzel still has to practice after x days is written as, N(x) = 210 - 30x

If the incomes in a certain larger population of college teachers have a normal distribution with mean of $60,000 and standard deviation of $5,000.the probability that their average salary exceeds $65,000 is 0.0228.

Probability is the tendency or likelihood that an event will happen.

First step is to find the standard deviation

Standard deviation= $5,000/√4

Standard deviation= $5,000/2

Standard deviation= $2,500

Second step is to find the z -score

Z= 65,000 - 60,000/2500

Z= 5,000/2500

Z= 2

Now let find the  pvalue of 2

pvalue of 2 = 0.0228

The probability that Sid takes one counter of each color is 0.5.

To find the probability that Sid takes one counter of each color, we need to know the total number of possible outcomes when Sid takes two counters from the bag. Since the order in which Sid takes the counters does not matter, there are two cases to consider:

Sid takes a green counter first and a blue counter second. There are 8 green counters and 3 blue counters, so there are a total of 8 * 3 = <<8*3=24>>24 outcomes in this case.

Sid takes a blue counter first and a green counter second. There are 3 blue counters and 8 green counters, so there are a total of 3 * 8 = <<3*8=24>>24 outcomes in this case.

In total, there are 24 + 24 = <<24+24=48>>48 outcomes when Sid takes two counters from the bag.

To find the probability that Sid takes one counter of each color, we divide the number of successful outcomes (24 in each case) by the total number of outcomes (48). This gives us a probability of 24/48 = 1/2 = 0.5.

The exact surface area of the cylinder in terms of π is = 10 π

What is the answer for surface area?

As a refresher, the surface area of an object is the sum of the areas of all of its faces, or the exterior surfaces of its three dimensions. It is calculated in square units.

Where can I find the surface area?

A three-dimensional shape's surface area is the total area on its surface. Add the areas of each of the six rectangular sides of a cuboid to determine its surface area. The cuboid's length, width, and height can also be labeled, and the surface area (SA) can be calculated using the formula SA=2lw+2lh+2hw.

Given that :

Radius = 1 1/4 cm

Height = 2 3/4 cm

Surface area is 2π r h + 2π r² = 2π ( 1 1/4 cm*2 3/4 cm) + 2π (1 1/4)²

= 2π (55/16) + 2π (25/16)

To graph a function with two variables, you need to plot the points that satisfy the function in a coordinate system.

For example, suppose you have a function f(x,y) = x^2 + y^2. To graph this function, you can choose a set of values for x and y that satisfy the function, and plot these points in the coordinate system.

For example, if you choose x = 1 and y = 2, then the point (1,2) satisfies the function because f(1,2) = 1^2 + 2^2 = 1 + 4 = 5. Similarly, if you choose x = -2 and y = 3, then the point (-2,3) satisfies the function because f(-2,3) = (-2)^2 + 3^2 = 4 + 9 = 13.

You can repeat this process for a range of values for x and y to plot more points in the coordinate system. As you plot more points, you will start to see a pattern emerge, which is the graph of the function.

Note that the graph of a function with two independent variables will be a surface in three-dimensional space, rather than a curve in two-dimensional space like the graph of a function with only one variable.
