Mathematics
1 answer:
Mekhanik [1.2K]3 years ago
6 0

<u>Answer:</u>

The solution of divide and lowest form of 2/ 1/4/13 is 6.5

<u>Solution:</u>

Given, expression is 2 / 1 / 4 / 13

We have to evaluate the given expression and reduce it to the lowest form.

Now, take the given expression

\begin{array}{ll}{\rightarrow} & {2 / 1 / 4 / 13} \\\\ {\rightarrow} & {(2 / 1) /(4 / 13)} \\\\ {\rightarrow} & {\frac{2}{1} / \frac{4}{13}}\end{array}

\Rightarrow \quad \frac{\frac{2}{1}}{\frac{4}{13}}

\begin{array}{cc}{\rightarrow} & {\frac{2}{1} \times \frac{13}{4}} \\\\ {\rightarrow} & {\frac{1}{1} \times \frac{13}{2}} \\\\ {\rightarrow} & {1 \times \frac{13}{2}}\end{array}

\Rightarrow \quad \frac{13}{2}

= 6.5

The result is already reduced to the lowest form.

Hence, the value of given expression is 6.5

Solve the logarithmic equation. Be sure to reject any value of log (X + 8) = log x + log 8​
swat32

Answer:

x = 8/7

Step-by-step explanation:

log (X + 8) = log x + log 8​

We know that log a + log b = log ab

log (X + 8) = log 8x

Raise each side to base 10

10^log (X + 8) = 10^log 8x

x+8 = 8x

Subtract x from each side​

x+8-x = 8x-x

8 = 7x

Divide by 7

8/7 = 7x/7

8/7 =x

What is the probability that the first card is a kingking and the second card is a kingking if the sampling is done with​ replac
IRINA_888 [86]
You want to draw 2 kings from a 52 card deck. And you do it with replacement.
There are 4 kings in a standard deck. The probability of getting one of them is 
4/52 on the first draw.

For the second draw the probability is the same.
4/52

The probability for both happening is 
(4/52)*(4/52) = (1/13)*(1/13) = 1/169 = 0.001597

Assume that adults have IQ scores that are normally distributed with a mean of 100 and a standard deviation of 20. Find the prob
Ipatiy [6.2K]

Answer:

Randomly selected adult has an IQ less than 136 is 0.9641

Step-by-step explanation:

It is given that, it is normal distribution with mean 100 and SD as 20.

So, let's use the formula of z-score

z=\frac{x-mean}{SD}

For this problem,

x= 136

Plug in this value into the formula

z-score=\frac{136-100}{20}

       =1.8

Now, use z-score table to find the probability

Find the corresponding value for the row 1.8 and the column 0.00, we do get 0.9641

So, Randomly selected adult has an IQ less than 136 is 0.9641
