Answer:

1. There are a fixed number of trials

2. There are two outcomes: success (getting a 4) and failure (not getting a 4)

3. You know the probability of success and it is the same for each trial

4. You are looking for the probability of getting a 4 exactly 3 out of 10 times. When you're looking for the probability of getting exactly x number of successes in n trials, that is a binomial probability distribution.

Step-by-step explanation:

Rounded to nearest hundredth: 18.85

Answer: x =  8

Step-by-step explanation: So you have 3 sides and 3 numbers. Identify the side that has a number without a variable. (This goes for both triangles) Then you divide the 1st number by the 2nd. In this case it would be 20 or side "B" divided by 5 or side "E", which equals 4. You then take 4 and multiply it by 4 or side "D" (Because it's the only other side that does not have a variable) and you take your answer (16) and 2x or side "A", and make an equation. The equation would be : 2 * x = 16. Now solve the equation. Your answer is : x = 8.

The total value of Matt's large assets, which include his investments, car, and house, adds up to $53,000.

The student is asking about calculating the total value of large assets that Matt owns. To find this, we add up the value of the investment, car, and house as these are considered large assets. The checking account is generally not included in large assets, as it is considered liquid cash rather than an asset of substantial value like property or investments.

We calculate the sum of these amounts to get the total value of Matt's large assets:

$15,000 + $8,000 + $30,000 = $53,000

Therefore, the total value of Matt's large assets is $53,000.

Step-by-step explanation:

(-0.86)

The residual value when x = 5 is -0.86.

Residual value is defined as the difference of the value that we predicts with that of the observed value.

It is given that,

Line of best fit is,

y = –0.7x + 2.36

Predicted value at x = 5 is,

y = -0.7 × 5 + 2.36 = -1.14

Observed value at x = 5 is y = -2

Residual value = Observed value - Predicted value

                         = -2 - -1.14

                         = -0.86

Hence the residual value is -0.86.

Step-by-step explanation:

It is given that, Steve is making a circular shield with a radius of 11 inches for a school play. We need to find the length of cardboard he need to make the outer border of the shield. It means that we need to find the circumference of the circular shield of radius 11 inches.

So,

[tex]C=2\pi r\\\\C=2\times 3.14\times 11\\\\C=69.08\ \text{inches}[/tex]

So, he will need 69.08 inches of cardboard to make the outer border of the shield.

Answer:

C

Step-by-step explanation:

We need to use the distance formula, which says that for two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], the distance between them is:

d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Here, the two points are (-2.5, 4.5) and (4.75, 4.5), so:

d = [tex]\sqrt{(4.75-(-2.5))^2+(4.5-4.5)^2}=\sqrt{(7.25)^2+(0)^2}=7.25[/tex] = 7 1/4

The answer is C.

Answer:

Step-by-step explanation:

Since the y-coordinate is the same, the two points lie on the same horizontal line

No vertical distance

Only horizontal distance of:

A measure of central tendency

Step-by-step explanation:

A measure of central tendency summarizes all of the values in a data set with one number.

A measure of central tendency describes how the values in a data set vary with a single number.

the three main measure of central tendency are the mean, median, and mode, all this three are single values attributed to values of a distribution.

The mean is the average value of a distribution

while the median is the middle value of a distribution and

the mode is the most occurrence value among the distribution.

Answer:

Step-by-step explanation:

let 7 + 3√2 be an rational number where

7+3√2 = a/b [ a and b are coprime and b is not equal to zero]

3√2= a/b-7

3√2 =( a-7b) /b

√2 = (a-7b) /3b .....(i)

Now ,from equation (i) ,we get that √2 is rational but we know that √2 is irrational. so actually 7 + 3√2 is irrational not rational. thus our assumption is wrong. The number is irrational.

Answer:

Prove by contradiction.

See below.

Step-by-step explanation:

Assume it is rational, then:

Let x = 7 + 3√2 = p/q      where p and q are integers and p/q is in simplest form.

x^2 = 49 + 42√2  + 18 = p^2/q^2

67q^2 = p^2  - 42√2q^2

67q^2 - p^2 = -42√2 q^2

67q^2 - p^2 is rational and q^2 is rational so that makes -42√2  rational.

but we know that -42√2  is irrational, so our original assumption is not true.

Answer:

y=7x+65

Step-by-step explanation:

You want to find the equation for a line that passes through the point (-9,2) and has a slope of 7.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was 7. So you can right away fill in the equation for a line somewhat to read:

y=7x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(-9,2). When x of the line is -9, y of the line must be 2.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the 7 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-9,2).

So, why not plug in for x the number -9 and for y the number 2? This will allow us to solve for b for the particular line that passes through the point you gave!.

(-9,2). y=mx+b or 2=7 × -9+b, or solving for b: b=2-(7)(-9). b=65.

The equation of the line that passes through the point (-9,2) with a slope of 7

is

y=7x+65

Step-by-step explanation:

The solution of the given system of equations using the graph is (0.6,2.2) so x is between 0 and 1 and y is between 2 and 3.

A graph is a diametrical representation of any function between the dependent and independent variables.

For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.

As per the given system of equations,

x + 2y = 5, –x + 3y = 6

Both systems of the equation have been plotted below.

The intersection point will be a solution as  (0.6,2.2).

0 < 0.6 < 1 and 0.6 can be rounded to the nearest tenth as 0.6.

2 < 2.2 < 3 and 2.2 can be rounded to the nearest tenth as 2.2.

Hence "The solution of the given system of equations using the graph is (0.6,2.2) so x is between 0 and 1 and y is between 2 and 3".
