Answer:
A = B + 15
Step-by-step explanation:
Let Diane sold B books in one hour,
Additional earning by selling 1 book = 1$
Additional earning by selling B books = Number of books sold × Additional earning by selling one book
= B × ($1.00)
= $B
Fixed earning of Diane in one hour of part time = $15
Total earnings = B + 15
A = B + 15
Table to find the input-output values for the graph,
A 15 16 17 18
B 0 1 2 3
Now we can plot the points on the graph.
Answer:
65°
Step-by-step explanation:
The consecutive interior angles theorem states that if two parallel lines are cut by a transversal line then the resulting pair of consecutive angles formed are supplementary (that is they add up to 180°).
Given that the painting rows are parallel to each other and a painted line (transversal) cut the parallel lines forming consecutive interior angles m∠1 and m∠2. Therefore:
m∠1 + m∠2 = 180°
m∠1 + 115 = 180
m∠1 = 180 - 115
m∠1 = 65°
The experimental probability of a certain event is the proability for that event to happen, "suggested" by some empiric experiments, instead of pure theory.
For example, we know that a fair coin has a 50% chance of landing on heads or tails. But if you throw a coin 100 times, with 60 heads and 40 tails, you would say that the probability for heads to show is 60%.
In your exercise, Jenny tried the experiment 50 times, and got a pink tile 18 times. So, according to her results, the probability of pulling a pink tile is
