The new price would be $105. To solve this, you need to figure out what 40% of 75 is. A simple way to do this is to figure out what 1%, or in this case 10%, of 75 is! Take 75 and divide it by 100, and you get .75. Doing this tells you what 1% of 75 is. Now, multiply .75 by 40, and you get 30! Now add 30 and 75, and you get 105. I hope this helped! Could I possible get brainliest?

Answer:

The standard deviation of the age distribution is 6.2899 years.

Step-by-step explanation:

The formula to compute the standard deviation is:

$SD=\sqrt{\frac{1}{n}\sum\limits^{n}_{i=1}{(x_{i}-\bar x)^{2}}}$

The data provided is:

X = {19, 19, 21, 25, 25, 28, 29, 30, 31, 32, 40}

Compute the mean of the data as follows:

$\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}$

$=\frac{1}{11}\times [19+19+21+...+40]\\\\=\frac{299}{11}\\\\=27.182$

Compute the standard deviation as follows:

$SD=\sqrt{\frac{1}{n}\sum\limits^{n}_{i=1}{(x_{i}-\bar x)^{2}}}$

$=\sqrt{\frac{1}{11-1}\times [(19-27.182)^{2}+(19-27.182)^{2}+...+(40-27.182)^{2}]}}\\\\=\sqrt{\frac{395.6364}{10}}\\\\=6.28996\\\\\approx 6.2899$

Thus, the standard deviation of the age distribution is 6.2899 years.

Given the following equation of the hyperbola, what are the x-values of the vertices? x^2/4 - y^2/49 = 1 is it 2 and -2?

Jet001 [13]

Answer:

yes, ±2

Step-by-step explanation:

The x-intercepts are found by setting y=0 and solving for x:

x^2/4 = 1

x^2 = 4

x = ±√4

x = ±2

The x-values of interest are -2 and +2.

Which equation in standard form has a graph that passes through the point (-4 , 2) and has a slope of 9/2?

malfutka [58]

Answer is <span>C. 9x-2y=-40

hope that helps

because y = 9/2x +20 then 2y = 9x + 40 so 9x -2y = -40
