Answer:
C) z = 1/2
Step-by-step explanation:
4z + 5 = 7
4z = 2
z = 1/2
3s = 72 (Multiply 8 both side).
s = 24 (divide by 3 both side)

Answer:
Step-by-step explanation:
<u>As per the given graph we have:</u>
Function f with dotted line (> or < sign), increasing function (slope is positive), y-intercept of -1 and shaded area A is to the right (so < sign), so this represents the inequality:
Function g with solid line (≥ or ≤ sign), decreasing function (slope is negative), y-intercept is 4 and shaded area B is to the left (so ≤ sign), so this represents the inequality:
<u>Correct system is C:</u>
Answer:
3/20 or 15%
Step-by-step explanation:
Out of 1,2,3,4, and 5, there are 3 prime numbers. This makes the odds of selecting one of those prime numbers 3/5. Then, saying that he does pick a prime number and discards that card, there are now four cards, one of them being the number one. His chances of selecting this card is 1/4.
To find the probability you need to multiply the two probabilities together.
3/5 times 1/4 is 3/20.
So your answer is 3/20 or 15%.
