I am pretty sure the answer is A because the graph is a cubic function
As it is only 5, it is 5/1 so you do 5 x 3 = 15 then 1 x 4 = 4. So 15/4
Answer: A.) For these data, as the number of at bats increases, the number of hits tend to increase.
This is because the points seem to trend upward as we move from left to right. This makes sense because the more attempts you get, the more hits you're expected to get.
Assume that someone has a batting average of 0.300; this means that if they got 1000 attempts, then we expect about 0.300*1000 = 300 hits. Now if they got 2000 at bats this time, then we expect about 0.300*2000 = 600 hits.
Of course things won't fit this perfectly since everything in life has random statistical error, but this gives a good idea of the upward trending data. The two variables (at bats and hits) are strongly related. We can say the variables have strong positive correlation.
Y = 0 so
x^2 + 6x - 40 = 0
(x +10)(x - 4) = 0
x+10 = 0; x = -10
x - 4 = 0; x = 4
answer is C. x = -10 and x = 4
√19 belongs to a set of irrational number
<h3>Irrational numbers</h3>
Numbers are irrational if they cannot be written as ratios or fractions of two numbers.
Examples of irrational numbers are √2, √3, √5, √11, √21, π, etc.
Since 19 is a prime number that can only be factored by 1 and itself, it is pairless and not in a power of 2.
Therefore, √19 belongs to the set of irrational numbers.
