Answer:

k = 3

Step-by-step explanation:

Subtract that one from the right side and then from the left side, so the equation should now look like (6 = 2k). Now you need to make the k be by itself to find what number it represents. So divide 2k by 2 and 6 by 2. So now the equation should look like (3 = k). (k = 3)

Lubov Fominskaja [6]

Answer:

The answer is "0.6227 and 0.5971".

Step-by-step explanation:

$\to p(x\leq 2)=p(0)+p(1)+p(2)$

$=e^{-2.2}(1+2.2^{1}+\frac{2.2^2}{2!})\\\\=0.6227$

$\to x \sim emp(\frac{1}{2.2})\\\\\to f(x)=\frac{1}{2.2} emp1-\frac{x}{2.2}$

$\to p(x \leq 2)=\int^{2}_{0} \frac{1}{2.2} emp1(-\frac{x}{2.2}\ dx$

$=1-emp1-2|2.2\\\\=0.5971$

What would this question look like after we change the mixed number to improper & use KCF to rewrite the question?

iris [78.8K]

Answer:

The question $3\frac{1}{2}\div\frac{1}{3}$ after change the mixed number to improper & using KCF will become : $\mathbf{=\frac{7}{2}\times \frac{3}{1}}$

Option B is correct option.

Step-by-step explanation:

We need to change the mixed number to improper & use KCF to rewrite the question.

The expression is: $3\frac{1}{2}\div\frac{1}{3}$

First converting mixed fraction into improper fraction

Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2

Solving:

$3\frac{1}{2}\div\frac{1}{3}\\=\frac{7}{2}\div\frac{1}{3}$

Using KCF

KCF stands fro Keep it, Change it, Flip it.

It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)

So, our expression will be

$=\frac{7}{2}\times \frac{3}{1}$

So, The question $3\frac{1}{2}\div\frac{1}{3}$ after change the mixed number to improper & using KCF will become : $\mathbf{=\frac{7}{2}\times \frac{3}{1}}$

Option B is correct option.
