Find the value of x . 12.5,-10,-7.5,x ; The mean is 11.5

Tems11 [23]

Answer:

51

Step-by-step explanation:

The mean is obtained by adding up the values in the data set and then divide by the number of values that you added:

$\bar X=\sum{X_i}\\$

Given our mean as 11.5 and n=4:

$\bar X=\frac{1}{n}\sum{X_i}\\\\\\\\\therefore\sum{X_i}\\=11.5\times 4=46$

#Knowing our sum as 65, we can obtain x by subtracting sum of known values from 65:

$x=46-(12.5+-10+-7.5)\\=51$

Hence, the value of x is 51

Please Help ASAP Evaluate (64^1/2)^-2/3

Naya [18.7K]

Answer:

Option A.

Step-by-step explanation:

The given expression is,

$[(64)^{-\frac{1}{2}}]^{-\frac{2}{3}}$

By solving the given expression,

$(64)^{-\frac{1}{2}}=\frac{1}{(64)^{\frac{1}{2}}}$ [Since $a^{-1}=\frac{1}{a}$ ]

$=\frac{1}{\sqrt{64}}$

$=\frac{1}{8}$

Now the expression will be,

$[(64)^{-\frac{1}{2}}]^{-\frac{2}{3}}=(\frac{1}{8})^{-\frac{2}{3}}$

$=8^{\frac{2}{3}}$

$={(\sqrt[3]{8})^2}$

= 2²

= 4

Therefore, value of the given expression will be 4.

Option (A) will be the answer.

Tennis balls are sealed in a pressurized container to maintain the rebound percentage

Darina [25.2K]

Answer:

Rounding the results to the next hundredth, we have:

Bounce 1: 2 * 0.55 = 1.10 meters

Bounce 2: 1.10 * 0.55 = 0.61 meters

Bounce 3: 0.61 * 0.55 = 0.34 meters

Bounce 4: 0.34 * 0.55 = 0.19 meters

Bounce 5: 0.19 * 0.55 = 0.10 meters

Bounce 6: 0.10 * 0.55 = 0.06 meters

Bounce 7: 0.06 * 0.55 = 0.03 meters

Step-by-step explanation:

Rebound percentage = 55% = 0.55

Bounce 1: 2 * 0.55 = 1.10 meters

Bounce 2: 1.10 * 0.55 = 0.605 meters

Bounce 3: 0.605 * 0.55 = 0.33275 meters

Bounce 4: 0.33275 * 0.55 = 0.1830125 meters

Bounce 5: 0.1830125 * 0.55 = 0.10065688 meters

Bounce 6: 0.10065688 * 0.55 = 0.05536128 meters

Bounce 7: 0.05536128 * 0.55 = 0.0304487 meters

Rounding the results to the next hundredth, we have:

Bounce 1: 2 * 0.55 = 1.10 meters

Bounce 2: 1.10 * 0.55 = 0.61 meters

Bounce 3: 0.61 * 0.55 = 0.34 meters

Bounce 4: 0.34 * 0.55 = 0.19 meters

Bounce 5: 0.19 * 0.55 = 0.10 meters

Bounce 6: 0.10 * 0.55 = 0.06 meters

Bounce 7: 0.06 * 0.55 = 0.03 meters
