Compare and contrast the methods you can use to multiply a whole number and a decimal

Troyanec [42]

Answer:

Answer with explanation

When you look at whole numbers , it begin from Zero and has no end , and decimal ,which is the set of rational numbers and irrational numbers, which came into consideration after whole numbers.

Whole number =0,1,2,3,4,5,6......

Decimal number = 0.1,0.25,0.325, 0.002000200002000002,..........

→0 × Any Decimal number =0

→ Any other whole number × A decimal number, gives

Convert that decimal into equivalent fraction,or if irrational number,write it up to three decimal places, and then multiply numerator with Numerator as denominator will remain unchanged to get the required result or multiply the decimal number with the whole number.

For example

→ Whole number × Terminating Decimal

5 × 0.25

$=5 \times \frac{25}{100}\\\\=\frac{125}{100}\\\\=0.25$

→Whole number × A non terminating repeating Decimal

2×0.22222222.......

$=2 \times \frac{2}{9}\\\\=\frac{4}{9}$

= An rational number, that is non terminating repeating decimal.

→→Whole number × An irrational number (A non terminating non repeating Decimal)

5 × √2=5 ×1.414(written to three decimal places)

=7.07(approx)

So, when there is an irrational number , write that decimal up to three decimal places, and then multiply that whole number by that irrational or decimal number to get the result.

a particular test correctly identifies those with a certain serious disease 94% of the time and correctly diagnoses those withou

Elodia [21]

This item can be solved by the probability theorem called Bayes' theorem which states that the probability of event A occurring given event B is equal to,
P(A/B) = P(A)P(B/A) / P(B)
where P(B/A) is the probability that the test will yield positive if the person has the disease. P(A) is the probability will be present in any particular person which is equal to 0.04.

P(B) is the probability of positive result irrespective of whether the disease is present of not is calculated below.
P(B) = (0.94)x (0.04) + (0.06)(0.96) = 0.0952

Now, solving for P(A/B)
P(A/B) = (0.94)(0.04) / 0.0952 = 0.039
Thus, the answer is approximately 4%.

A hiker leaves camp at 6 A.M. to begin his descent from an elevation of 3,200 feet. He descends at the rate of 800 feet per hour

Pavel [41]

B will be 3,200 since it is the starting elevation.
Always, b is the number when x is 0. Here, x is the number of hours he descends from. So, at 0 hours, meaning when he starts descending, his elevation is b..
