What is 1 and 2 10ths written as a decimal?

1 answer:

8 0

1 is the whole number which means it goes before the decimal point. 2/10 is the fractional piece making it go after the decimal point in the tenths place.

1 2/10 = 1.2

When you divide by a fraction, flip the fraction over and change divide to multiply:

3/2 / 1/8 would become:

3/2 x 8/1

8/1 simplifies to 8

You get:

3/2 x 8 = 12

The answer is:

Three-halves times 8 = 12

We roll a fair die repeatedly until we see the number four appear and then we stop. The outcome of the experiment is the number

muminat

Answer:

Step-by-step explanation:

given that we roll a fair die repeatedly until we see the number four appear and then we stop.

the number 4 can appear either in I throw, or II throw or .... indefinitely

So X = the no of throws can be from 1 to infinity

This is a discrete distribution countable.

Sample space= {1,2,.....}

b) Prob ( 4 never appears) = Prob (any other number appears in all throws)

= $\frac{5}{6} *\frac{5}{6} *\frac{5}{6} *\frac{5}{6} *...\\=(\frac{5}{6} )^n$

where n is the number of throws

As n tends to infinity, this becomes 0 because 5/6 is less than 1.

Hence this probability is approximately 0

Or definitely 4 will appear atleast once.

find 2 consecutive integers such that three times the square of the first is equal to seven more than five times the second

melamori03 [73]

Answer:

Step-by-step explanation:

We are looking for two numbers, $N$ and $N + 1$ . From the problem statement, we can setup the following equation:

$3N^{2} = 5(N + 1) + 7$

$3N^{2} = 5N + 5 + 7$

$3N^{2} - 5N - 12 = 0$

$(3N + 4)(N - 3)$

$N = \frac{-4}{3}, 3$

Because 3 is the only integer solution, the answer is 3 and 4.
