Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is 
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.
The probability of matching three out of five numbers is 153/33649
<h3>How to determine the probability?</h3>
The numbers are given as:
1 to 23
There are five matching numbers
The probability of getting a match is:
p = 5-k/n where k = 0, 1, 2
While the complement probability is
q = (n - 2)/n
Using the above formulas, the probability of getting from 5 is:
P = 5/23 * 4/22 * 3/21 * 18/20 * 17/19
Evaluate the product
P = 153/33649
Hence, the probability of matching three out of five numbers is 153/33649

Answer:
0.6 + 15b + 4 = 25.6 all equivelant
0.6 + 15b + 4 = 25.6 all equivelant
0.6 + 15b + 4 = 25.6 all equivelant
0.6 + 15b + 4 = 25.6 all equivelant
0.6 + 15b + 4 = 25.6 all equivelant
0.6 + 15b + 4 = 25.6 all equivelant
Step-by-step explanation:
0.6 + 15b + 4 = 25.6 all equivelant
0.6 + 15b + 4 = 25.6 all equivelant
0.6 + 15b + 4 = 25.6 all equivelant
0.6 + 15b + 4 = 25.6 all equivelant
0.6 + 15b + 4 = 25.6 all equivelant
If a graph fails the vertical line test it's not a function; you can't have a single x map to two ys.
Vice versa, if the graph passes the verticle line test, it's a function.
The horizontal line test tests for injectivity aka one-to-one-ness; it has no bearing on whether something's a function.
