A sample of 75 concrete blocks had a mean mass of 38.3 kg with a standard deviation of 0.6 kg.

Response:

x² + -6x = -13

Detailed breakdown:

8x² - 48x = -104

Rearranging gives us x² - 6x = -13

Isabella can pour a maximum of 8 full glasses. With 1.75 liters converted to milliliters being 1750, dividing that by 200 gives 8.75 cups.

4.2x - 1.4y = 2.1
-1.4y = 2.1 - 4.2x
y = \frac{2.1 - 4.2x}{-1.4}
y = 3x - 1.5 <==

Response:

12.

Step-by-step explanation:

We have been given a format for various numbers. Our task is to discover the missing value for our specified format.

Taking the square root of 9 and 16 results in

Moreover, it can be observed that by computing the square root of all figures on the left side of the equation and summing them, we arrive at the right side.

Upon extracting the square roots of 25 and 49 we deduce,[TAG_48]]

Therefore, the missing number in our sequence is 12.

The answer to the problem is 36,300 cm.
