7*30=210
+15 (1/2 of 30)=225

The mean score of 8 players is 14.5. If the highest individual score is removed the mean of the score of the remaining 7 players

AfilCa [17]

Answer:

The highest score is 32.

Step-by-step explanation:

We are given the following in the question:

The mean score of 8 players is 14.5.

Let x denote the highest score.

If x is removed, the mean of the score of the remaining 7 players is 12.

Formula for mean:

$\bar{x} = \dfrac{\displaystyle\sum x_i}{n}$

Putting values, we get:

$14.5 = \dfrac{\displaystyle\sum x_i}{8}\\\\\Rightarrow \displaystyle\sum x_i = 116\\\\12 = \dfrac{\displaystyle\sum y_i}{7}\\\\\Rightarrow \displaystyle\sum y_i = 84\\\\\displaystyle\sum y_i = \displaystyle\sum x_i -x \\\\84 = 116 - x\\\Rightarrow x = 32$

Thus, the highest score is 32.

Solve for X<br><br> 4X-(9-3X)=8X-1

Nataliya [291]

4x - (9 - 3x) = 8x - 1

4x - (9) - -(3x) = 8x - 1

4x - 9 + 3x = 8x - 1

7x - 9 = 8x - 1 (-8x from each side)

-x - 9 = -1 (+9 to each)

-x = 8 (divide -1 from each side)

x = -8

Use the pencil,plot the point (3 1/2, 2 3/4)

kipiarov [429]

Answer:

The diagram of the plotting point $\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)$ is attached below.

Step-by-step explanation:

Given the points

$\left(3\frac{1}{2},\:2\frac{3}{4}\right)$

$3\frac{1}{2}=\frac{7}{2}=3.5$

$2\frac{3}{4}=\frac{11}{4}=2.75$

so the point can be visualized as:

$\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)$

Now, we can check the point x = 3.5, and determine the corresponding value y = 2.75 and plot the point at the location (x, y) = (3.5, 2.75)

The diagram of the plotting point $\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)$ is attached below.

a sticker price on a new vehicle is $33985 , but the dealer cost is $27700 and you want to offer 4% over the dealer cost. what w

Alexandra [31]

To find the price of the dealer cost, you should multiply 27700 by 4% and add the amount to 27700.

4%, in decimal form (so we can easily multiply it), is 0.04.

27700 * 0.04 = 1108

27700 + 1108 = 28808

The answer is 28808 dollars.
