Answer:
Same here !
My guess is when you reach Genius on Brainly, you MAY be able to chat.
That's is my guess.
I have had many many different accounts on Brainly and, no chat.

Answer:
Since he earned one third as many as Jose
it's 8
Step-by-step explanation:
Answer:
Explanation: start by adding 34 to both sides to make the variable stand alone giving you
7y is greater than or equal to 42
Then divide 7 into both sides to give you the answer of
Y=6
Answer:
E(x)=0.15
V(x)=0.3075
S(x)=0.5545
Step-by-step explanation:
The mean of a discrete variable is calculated as:

where
are the values that the variable can take and
are their respective probabilities.
So, if we call x the number of defective transistors in cartons, we can calculate the mean E(x) as:

Because there are 0 defective transistor with a probability of 0.92, 1 defective transistor with a probability of 0.03, 2 defective transistors with a probability of 0.03 and 3 defective transistors with a probability of 0.01.
At the same way, the variance V(x) is calculated as:

Where 
So, the variance V(x) is equal to:

Finally, the standard deviation is calculated as:

The answer will basically be 11^3, because 11^3÷11^3=1, and 1 times 11^3 equals 11^3, which, if you want to put down the integer answer, would be 1,331.
