Answer:

3x + 2 = 50

Step-by-step explanation:

The reason for this equation is that each friend gets 3 chocolates or 3x, x being the number of friends.

The 2 is the 2 chocolates that are left which can be subtracted from 50 on the other side to have the equation 3x = 48.

X would then equal to 16 people.

A local health clinic surveys its patients about their waterdrinking habits. It found the data is normally distributed,the mean
satela [25.4K]

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

water drinking habits:

mean = 62 ounces

standard deviation = 5.2 ounces

Step 02:

normally distribution:

95% ===> 2 SD

(62 + 5.2 + 5.2) ounces = 72.4 ounces ==> + 2 SD

(62 - 5.2 - 5.2) ounces = 51.6 ounces ==> - 2 SD

The answer is:

51.6 ounces - 72.4 ounces

Lemur [1.5K]

The <em><u>correct answer</u></em> is:

7.8 × 10⁷

Explanation:

To write a number in scientific notation, we want the decimal behind the first non-zero digit in the number. The first non-zero digit in 78 is 7; this means we want 7.8. In order to have the decimal point behind the 7, we need to move the decimal 7 places. This is the exponent of 10 in our scientific notation, which gives us
