Answer:
$385
Step-by-step explanation:
This would be 50x7=350
And 60 is 10 over 50, we half his salary($3.50), and multiply $3.50 by that extra 10. coming to $35. Add 35 to 350 to get his $385 60 day salary
Answer:
45 square meters
Step-by-step explanation:
we know that
The area of trapezoid is equal to

where
b1 and b2 are the parallel bases
h is the height of trapezoid (perpendicular distance between the parallel bases)
we have

substitute


Answer:
The maximum is -3
Step-by-step explanation:
A parabola that opens down (- in front), the vertex represents the highest point on the graph, or the maximum value.
The vertex of the equation is (-7,-3)
So, the maximum y value is -3
Answer: 26
Step-by-step explanation: The order of operations says to divided 8 and 2 first, which gives you 4. 18+4=22. Plus 4 again is 26
Answer:

Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
For this case we want this probability:

And we can use the complement rule like this:
And we can find the individual probabilities like this:


And in order to do the operations we can use the following excel code:
"=1-BINOM.DIST(8,25,0.3089,TRUE)"
And we got:
