What is the product of −2 2/5 and −3 5/6 ?

The mean age and median age of 6 people in a room is 40 years. a person whose age is 60 years leaves the room. question 1. if po

FromTheMoon [43]

Mean = (total of contributors) / (number of contributors)

For the 6 people in the room, you have
40 = (total of contributors) / 6
(total of contributors) = 6*40 = 240

A 60-year-old left the room, decreasing the total of contributors by 60.
(new total of contributors) = (total of contributors) - 60
(new total of contributors) = 240 - 60 = 180

Then the new mean is
(new mean) = (new total of contributors) / (new number of contributors)
(new mean) = 180 / 6 = 36

The mean age of the remaining 5 people is 36.

Convert from Decimal Notation to Scientific Notation

oee [108]

Answer:

Hence, 3,40,000 can be expressed as $3.4\times10^5$

Step-by-step explanation:

Step 1 of 1

Consider 3,40,000

3.4

So, 3.4 lies between 1 & 10

Now, Decimal has moved 5 places to left.

$3.4=10^{5}$

So, 3,40,000= $3.4 \times 10^{5}$$

List three ways o express 3 to the 5 power as a product of powers

tia_tia [17]

3 ways to express 3 to the 5th power as the product of powers First expression => 3 x 3 x 3 x 3 x 3 - In this expression, we multiplied 3 5 times and the product is 243 Second expression => 3 ^ 5, in where ^ read as raised to the power, the product is also 243 Third expression => 3^2 x 3^3 => (3 x 3) x (3 x 3 x 3) => 9 x 27, the product also equals to 243.

Using the z-distribution, the p-value would be given as follows:

b) 0.0086.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis we test if the means are equal, hence:

$H_0: \mu_D - \mu_C = 0$
