50^2 = 50 to the power of 2 = 2.5 × 10^3

Explanation:

(50) to the 2nd power or simply '50 to the 2nd' is obtained by multiplying 2 times the base 50 by itself. So,

50^2 = 50 × 50 = 2.5 × 10^3

Note: We say that 50 is the base, 2 is the exponent, and the whole thing or the result is a power of 50.

Answer:

$\large\boxed{x=-\dfrac{44,475}{64}}$

Step-by-step explanation:

$-4\sqrt[3]{x+25}=35\\\\\left(-4\sqrt[3]{x+25}\right)^3=35^3\\\\-4^3(x+25)=42,875\\\\-64(x+25)=42,875\qquad\text{use distributive property}\\\\-64x-1,600=42,875\qquad\text{add 1,600 to both sides}\\\\-64x=44,475\qquad\text{divide both sides by (-64)}\\\\x=-\dfrac{44,475}{64}$

The day of the 52-mile double marathon is finally here! Pepe has set the ambitious goal of averaging an 8-minute mile. Pepe fini

balandron [24]

Answer:

221 minutes

Step-by-step explanation:

His goal is 8 minutes or less for every mile during the marathon.

8 x 52 = 416

That gives him 416 total minutes to complete the marathon goal.

He already ran the first half in 195 minutes, so we do this to find the time for the other half:

416 - 195 = 221

He has 221 minutes in the second half of the marathon to meet his goal.

A family goes grocery shopping every week. in a month the costs of the groceries are $72.42, $91.50, $58.99, and $69.02. 5. what

frozen [14]

1) Mean
The mean is given by the sum of the data divided by the number of data (4, in this case):
$\mu = \frac{1}{N} \sum x_i = \frac{1}{4}(72.42+91.50+58.99+69.02) = \frac{291.93}{4}=72.98 $$

2) Standard deviation
The standard deviation is given by:
$\sigma = \sqrt{ \frac{1}{N} \sum (x_i-\mu)^2 }$
where $\mu$ is the mean, that we already found at point 1), and N=4. Substituting data, we have:
$\sigma = \sqrt{ \frac{1}{4} ((-0.56)^2+(18.52)^2+(-13.99)^2+(-3.96)^2) } =$
$= \sqrt{ \frac{1}{4} (554.71)} = \sqrt{138.68} =11.78 $$
