The answer
y=−x^2−2x-24 is like the form of y=ax² +bx +c, to find the vertex we use the formula:
the x intercept according to the vertex is x=-b/2a, and the vertex V is a point such that V [-b/2a, f(-b/2a)]
the x intercept is x= -(-2) / 2(-1) =-1, and f(-1)= -1 +2 -24= -23
the vertex is V(-1, -23)
Answer:
5/52
Step-by-step explanation:
There are 52 cards in a deck, with 26 red and 26 black cards. There are 2 red ones, 2 black threes, and 1 six of hearts. The # of favorable outcomes is 2 + 2 + 1 = 5, so the answer is 5/52.
Answer:
50 for part 1. 1/2 for part 2. Part 3 As likely as not.
Step-by-step explanation:
For part 1, To write the decimal as a percent, write the decimal as a fraction with denominator 100. The numerator of the fraction is the percent.
For part 3, The probability of an event is a number from 0 to 1 that measures the likelihood the event will occur. If the probability is between 0 and 0.5, the event is unlikely to occur. If the probability is between 0.5 and 1, the event is likely to occur. If the probability is 0.5, the occurrence of the event is as likely as not.
