5y and 155 create a straight line so:
5y + 155 = 180
5y = 25
y = 5
5y and 13x create a 90 angle so:
5y = 5(5) = 25
25 + 13x = 90
13x = 65
x = 5
Hope this helps :)
Recall that for

, i.e. a random variable

following a binomial distribution over

trials and with probability parameter

,

So you have




The expected value of

is simply

, while the standard deviation is

. In this case, they are

and

, respectively.
Answer:
False.
Step-by-step explanation:
It is false because when dividing an odd number by an odd number, it usually isn't divisible. In this case, 690,26<u>9</u>. Is an odd number, because the last number, 9, is odd, which makes the whole thing odd. So, odd divided by odd never turns out well. (By the way the answer is 76,696.5555556).
Answer:
55 ≤ x ≤100
Step-by-step explanation:
Given the battery life equation: y = -10x +100 where x is hours driving
As we know that the maximum value of y = 100% when x= 0
<=> y ≤100
They are driving from Dallas to San Antonio which is a 4.5-hour drive.
=> x = 4.5 so we substitute x into the equation, we have:
y = -10*4.5 +100
<=> y = -45 + 100 = 55
Hence, the range of this situation is:
55 ≤ x ≤100
Hope it will find you well.
