What is 39.79949748 rounded to the nearest hundredth?
Rufina [12.5K]

Answer:

Number = 39.80

Step-by-step explanation:

Given

Number = 39.79949748

Required

Approximate (to the nearest 100th)

This means that, we approximate at the second digit after the decimal.

So:

i.e,

Number = 39.79  [Begin  approximation] 949748

The first digit after [Begin approximation] is then approximated using the following rule:

0 - 4 \approx 0

5 - 9 \approx 1\\

Since 9 falls in 5 - 9 \approx 1\\ category, the number becomes:

Number = 39.[79+1]

Number = 39.80

A test of 10 different types of candy are being tested. If a person is given 6 of the candies to taste how many combinations are
ASHA 777 [7]

There are 210 different possible combinations

<h3>How to determine the number of possible combinations?</h3>

The given parameters are:

  • Types of candy, n = 10
  • Candies to taste, r = 6

The number of possible combinations is calculated using:

Combination = nCr

This gives

Combination = 10C6

Apply the combination formula

Combination = (10!)/((10 - 6)!6!)

Evaluate

Combination = 210

Hence, there are 210 different possible combinations
