Step-by-step explanation:

To find the expected waiting time for a random call from the sampie given by using the formula:

$\sum (f(X)) = \dfrac{\sum f (x) \times x}{\sum x}$

number of calls (x) waiting time f(x) in minutes f(x) *(x)

0 0 0

2 3 6

4 10 40

6 15 90

8 10 80

10 6 60

$\sum x = 30$ $\sum f(x) *x = 276$

Therefore:

$\sum (f(X)) = \dfrac{276}{30}$

$\sum (f(X)) = 9.2$

The mass of Mars is 6.42x10-23 kilograms. The mass of mercury is 3.3x10-23 kilograms. What is the combined mass in scientific no

Paraphin [41]

<em>combined mass in scientific notation can be written as</em> 97.2× $10^{-24}$ kg

Scientific notation can be regarded as a way of writing very large as well as very small numbers.

Mars of mass= (6.42x $10^{-23}$ kg )

Mercury= (3.3x $10^{-23}$ kilograms)

Then we add together

(6.42x $10^{-23}$ )+ (3.3x $10^{-23}$ ) kilograms.

= 9.45 × $10^{-24}$ kilograms

Therefore, combined mass in scientific notation can be written as 97.2× $10^{-24}$ kg

SIZIF [17.4K]

Answer:

Step-by-step explanation:

i believe you just have to add the fractions together since the denominator are the same :)

$\frac{6}{8} + \frac{5}{8} = \frac{6 + 5}{8} = \frac{11}{8}$

So in total Hazel can produce $\frac{11}{8}$ Liters of juice
