Answer:
Step-by-step explanation:
-p(d + z) = -2z + 59
-pd - pz = -2z + 59
+pd +pd
-pz = pd - 2z + 59
+2z +2z
pz + 2z = pd + 59
(p + 2)z = pd + 59
÷(p+2) ÷(p+2)
Answer:6.15
Step-by-step explanation:
change 2.5% by dividing by 100. 2.5÷100=0.025. Then multiply 6 by 0.025. 6×0.025=0.15. Then add 0.15 to 6 for the answer. 6+0.15=6.15.
Answer:
1/6, 1/4.
Step-by-step explanation:
The theoretical probability of rolling a 2 on a single roll of a number cube is 1/6, because there are 6 numbers ( 1 to 6) on a cube.
The theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue, 1 red, and 1 orange section is 1/4, because there are 4 different colours on the spinner.
Answer:
D
Step-by-step explanation:
the range is D because the vertex, or maximum value of the graph is at y = -1. The graph then goes downward completely, so the range is numbers including and below -1.
