EleoNora [17]

Answer:

The answer is "0.096".

Step-by-step explanation:

In this question, the X is a number of the students who enroll in a psycholog y course, follows a Poisson distribution with mean $= \lambda= 105$

$\therefore P(X=x)=\frac{e^{-105} 105^{x}}{x!},(x=0,1,2,3.....)\\\\\to p(teach\ two \ sections) = P(X \geq 119)\\\\=1-P(X$

I will give you 100 points if you can answer this<br><br> (66×578)÷3368=55÷77=???

erma4kov [3.2K]

(66✖️578) ➗ 3368=55➗77

P parentheses
E exponents
M multiplication
D division
A addition
S subtraction

You would do (66✖️578) first since it is in parentheses
66✖️578=38,148

38,138➗3368=55➗77
Since there are no exponents or multiplication you would do division

38,138➗3368= 11.3236342
55➗77=0.7

11.32 does not equal 0.7
So this equation would be false

Hope this helps! :3

Burka [1]

Answer:

$\sqrt{2}$ or 1.414

Step-by-step explanation:

1) Find the mean. 1+2+3+4+5 = 15. 15/5= 3

2) For each data point, find the square of its distance to the mean. (4, 1, 0, 1, 4)

3) Sum the values from Step 2. 10

4) Divide by the number of data points. 10/5= 2

5) Take the square root. $\sqrt{2}$
