Answer:
three thousand three hundred and fifty.3,350
Step-by-step explanation:
the question given was:1/4 take a speech, so how many?: one fourth, if you divide 13,400 by 4 its 3,350. that is one fourth of 13,400. So, if you add 3,350 four times, it would be 13,400.
Hope this helped!<3
Answer: i think you are supposed to subb in the x and h for something i just dont know what it is im not that smrt sorry i would thing it is 4 for x then the one would turn negative because in the equation it is subtraction so just do 4(4)^2+4-1 for the first one
the second one just do the same thing sub in the same numbers so it would be 4(4+1)-4(4)/1 i think it will get your answer brainliest plz

Answer:
Slope
Step-by-step explanation:
In the regression equation y=a+bx, y is dependent variable and x is independent variable. It means that due to change in x the y changes respectively. The "a" is intercept of the model and it shows the value of y when x is zero. The "b" is the slope of the model and it depicts the change in y due to unit change in x. The positive value of b means that as the x increases y also increases and as the x decreases y also decreases. The negative value of b means that as the x decreases y increases and as the x increases the y decreases.The sign of b shows the type of relationship between independent and dependent variable.
Answer:
0.9999
Step-by-step explanation:
Let X be the random variable that measures the time that a switch will survive.
If X has an exponential distribution with an average life β=44, then the probability that a switch will survive less than n years is given by
So, the probability that a switch fails in the first year is
Now we have 100 of these switches installed in different systems, and let Y be the random variable that measures the the probability that exactly k switches will fail in the first year.
Y can be modeled with a binomial distribution where the probability of “success” (failure of a switch) equals 0.0225 and
where
equals combinations of 100 taken k at a time.
The probability that at most 15 fail during the first year is
