Answer:

(x ÷ 2) + 7

Step-by-step explanation:

A quotient is the answer to a division problem...

So.... Let's say "a number" is x

(x ÷ 2) + 7 = Seven more than the quotient of a number and 2

That should be the answer!

Using the binomial distribution, the expected number of distinct toy types that you will have after you have collected t toys is:

E(X) = t/n.

The binomial probability distribution gives the probability of exactly x successes on n repeated independent trials, with p probability of a success on each trial.

The expected value of the binomial distribution is calculated as follows:

E(X) = np.

In the context of this problem, the symbolic values of the parameters are given as follows:

Hence the expected number of distinct toy types that you will have after you have collected t toys is calculated as follows:

E(X) = t x 1/n = t/n.

Answer:

(-3, -3)

Step-by-step explanation:

1.) Rewrite the second equation so 3y is on one side of the equation:

3y=6+5x

2.) Substitute the given value of 3y (replacing 3y with 6+5x, since we know they equal each other) into the equation 17x=-60-3y

Should end up with this:

17x=-60-(6+5x)

3.) Solve 17x=-60-(6+5x)

Calculate Difference: 17x=-66-5x

Combine Like Terms: 22x = -66

Divided both sides by 22 to isolate and solve for x: -3

So We know x=-3, now we got to find the y value. We can use either the first or second equation to find y value, so lets use the second.

3y=6+5x

1.) We know that x=-3, so we can simply substitute x in the equation

3y=6+5x with -3

3y=6+5(-3)

2.) Solve 3y=6+5(-3)

Combine Like Term: 3y=6+-15

Combine Like Term Even More: 3y= -9

Divide by 3 on both sides to isolate and solve for y: y=-3

So now we know y=-3 and once again we know x=-3, so if we format that

(-3,-3)

Step-by-step explanation:

Based on the historical data provided by Glassboro Associates regarding the sales of electric cars, a forecast can be developed using the time-series analysis method, specifically, the moving average method.

The moving average method is a time-series analysis method that involves taking the average of the most recent n data values in a time series to forecast future values. This method assumes that future values are based on past behavior.

The formula for the moving average method is:

Forecast = (n1 + n2 + n3 + ... + nn) / n

Where n = the number of periods to be averaged, and n1, n2, n3, ... nn = the most recent n data values in the time series.

The historical data is shown in the table below:

Quarter Year 1 Year 2 Year 3 1 125 151 159 2 118 130 168 3 208 227 221 4 198 200 273

To develop a forecast, we will use the moving average method with n = 4. We will use the most recent four data values in each year to calculate the moving average forecast.

The forecast for each quarter of Year 1, Year 2, and Year 3 is shown in the table below:

Quarter Year 1 Year 2 Year 3 1 - - - 2 - - - 3 - - - 4 175.25 187.0 205.5

Therefore, the forecasted sales for Year 1, Year 2, and Year 3 are as follows:

Year 1 = 175.25 + 187.0 + 205.5 + 159 = 727.75

Year 2 = 187.0 + 205.5 + 159 + 168 = 719.5

Year 3 = 205.5 + 159 + 168 + 273 = 805.5

The forecast for Glassboro Associates' sales of electric cars over the next three years using the moving average method with n = 4 are 727.75, 719.5, and 805.5 for Year 1, Year 2, and Year 3, respectively.

Step-by-step explanation:

Remark

What you don't know and what makes the problem confusing, is that where to the given arcs start and end. So I am going to say that both arcs start from E and 119 ends at D, and 174 ends at F which means that the arc FD is not known, but it is not hard to find.

The total number of degrees from beginning to end is 360 degrees. The formula for finding FD is

Formula

FD = 360 - (174 - 119)

The formula for x is (ED - FD)/2

Solution

Arc FD = 360 - (174 - 119)

Arc FD = 67

So x = (119 - 67) / 2

x = 52 /2

x = 26

Answer:

the circle's radius is approximately 13.00 feet.

Step-by-step explanation:

The t times u is approximately equal to -139.7.

To find t times u, we use the formula for the dot product: t · u = |t||u|cosθ, where θ is the angle between the vectors. Since we are only given the vectors t and u, we need to find their magnitudes and the angle between them.

The magnitude of t is |t| = √(7^2 + (-3)^2) = √58, and the magnitude of u is |u| = √((-10)^2 + (-8)^2) = √164.

To find the angle between t and u, we use the formula cosθ = (t · u)/(|t||u|). Substituting the values we know, we get cosθ = ((7)(-10) + (-3)(-8))/((√58)(√164)) = -74/(2√1017). Using a calculator, we find that θ ≈ 131.5 degrees.

Now we can find t · u: t · u = |t||u|cosθ = (√58)(√164)(cos(131.5)) ≈ -139.7.

Step-by-step explanation:

For dilated figures, the ratio of volumes is the cube of the ratio of corresponding linear dimensions.

  Vn/Vm = (Hn/Hm)³

  Vn = Vm(Hn/Hm)³ = (68 2/5 ft³)((2 3/8 ft)/(4 3/4 ft))³

  Vn = (342/5 ft³)((19/8)/(19/4))³ = (342/5 ft³)(1/2)³ = 342/40 ft³

  Vn = 8 11/20 ft³

The volume of Prism N is 8 11/20 ft³.

What are you asking of us? To work out the value of X and Y?

Since the given zeros are i and -13+i, their conjugates must also be zeros of the polynomial. The conjugate of i is -i and the conjugate of -13+i is -13-i.

Therefore, the four zeros of the polynomial are i, -i, -13+i, and -13-i.

Since the degree of the polynomial is 4, and we have already accounted for all four zeros, there are no remaining zeros.

To determine the remaining zeros of the polynomial, we need to consider that complex zeros always appear in conjugate pairs. Given the zeros i and -13 + i, the remaining zeros are -i (conjugate of i) and -13 - i (conjugate of -13 + i).

Answer:

d = 47°

Step-by-step explanation:

Image is attached

Sum of angles drawn along a straight line = 180°:

The angle drawn in pink : 180° - 112° = 68°

The angle drawn in green: 180° - 66° = 114°

The angle drawn in yellowish orange: 180° - 23° = 157°

The angle marked in purple: 180° - 102° = 78°

The figure drawn in the center is a 5-sided irregular pentagon

∴ Sum of interior angles in a 5-sided polygon = (n - 2) ×180°

                                                                            = (5 - 2) × 180°

                                                                            = 540°

The four angles calculated above will assist in calculating the fifth remaining angle of the pentagon (which is marked in light blue):

   68° + 114° + 78° + 157° + angle in light blue = 540°

Angle in light blue = 540° - 68° - 114° - 78° - 157°

                               = 123°

Sum of angles drawn along a straight line = 180°:

Angle marked in dark blue = 180° - 123°

                                                = 57°

Now focus on the angles present inside the triangle

Sum of interior angles of a triangle = 180°

= d + 76° + 57° = 180°

d has to be isolated and made the subject of the equation:

d = 180° - 76° - 57°

d = 47°

Answer: Trinomial

Answer:

Step-by-step explanation:

With an eight team round robin, 28 games will be played in total (The total edges in K8). Since each game will produce two points regardless of outcome, 56 total points will be shared among the eight teams. In the absence of a well-defined tie breaking system, we assume that ties do not qualify as a guarantee. We define a team's point total as "ensuring" fourth place when the fifth place team could not possibly have that many points.

Ten points are not enough and eleven points must be enough. In one extreme case, teams A,B,C,D and E all draw each other and win against F,G, and H (who also draw each other), giving a fifth place team with ten points. If we have a fifth place team with eleven points then teams A,B,C,D, and E share at least 55 points, meaning teams F,G, and H share at most one point. However, F,G, and H play each other and must share at least six points, a contradiction. Therefore, 11 points guarantees fourth place at a minimum.
