Lubov Fominskaja [6]

Answer:

The answer is "0.6227 and 0.5971".

Step-by-step explanation:

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

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

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

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

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

F(x) = 4x2 – 10x + 2<br> Find f(-7)

eimsori [14]

Answer:

f(-7) = 268

Step-by-step explanation:

f(x) = 4x^2 – 10x + 2

Let x = -7

f(-7) = 4(-7)^2 – 10(-7) + 2

Exponents first

f(-7) = 4(49) – 10(-7) + 2

Multiply

f(-7) = 196 + 70 + 2

f(-7) = 268

Your waiter at a restaurant suggests you leave a tip of $10 on a $50 bill. What percentage is that?

Bezzdna [24]

Answer:

20%

Step-by-step explanation:

To find what percentage is $10 out of $50, we divide 10 by 50:

$\frac{10}{50}=0.2$

If we want to get the result in percentage form, we simply multiply it by 100%:

$0.2\cdot 100\%=20\%$

So a tip of $10 on a $50 bill is a tip of 20%.
