<em>Answer:</em>
n²+3
<em>Explanation:</em>
The differences between the terms are not the same, so this is not "linear". Knowing that the sequence may have started with a 1, you can try subtracting the first number with a number to get 1, and use that number to subtract the rest.
4 - 3 = 1
7 - 3 = 4
12 - 3 = 9
19 - 3 = 16
28 - 3 = 25
In this case, subtracting 3 to all the numbers gave us perfect squares! So this means the nth term has to do with squaring the number and adding three afterward! This can be checked.
√1 = 1
√4 = 2
√9 = 3
√16 = 4
√25 = 5
As we found the values of these terms by subtracting three first and then finding its square root, the nth term will be the opposite; squaring and then adding three! Again, this can be checked!
1² + 3 = 4
2² + 3 = 7
3² + 3 = 12
4² + 3 = 19
5² + 3 = 28
Hope this helps !! :D
Answer:
Explanation has been given below
Step-by-step explanation:
hope fully it may concern with 70% adults then
p = 0.77
randomly select = 6
then mean will be
mean = n * p = 6*0.77=4.62
To get variance np (1-p)
then putting values we get
np (1-p) = 4.62 *0.23 = 1.0626
taking square root we get
sd = 1.03
Most samples of 6 adults would differ from the mean by no more than 1 sd
mean is differ by no more than 2 sds .
In a real-life situation, it is expected that 4 or 5 of 6 to think it is a problem.
I would not expect 0, 1, or 2.
Answer:
la respuesta es la primera ( a )
Step-by-step explanation:
x=43
you subtract 47-90. 90 because 47 is part of a right angel.
x is the same as the missing part of the right angle including 47
