The probabilities add up to 1 because probabilities are measured in percentages. 1 = 100%, 0.5 = 50%, etc. If the probability of an outcome was 1, there would be no other possible outcomes because that outcome would have a 100% chance of occurring each time.
Answer:
c
Step-by-step explanation:
From the order of operations, we do parens, then multiply/divide, then add/subtract, rewriting each step to keep everything clear:
(14) - 2 - (50 ⋅ 2) <span>⋅ 1 - 1
14 - 2 - 100 </span><span>⋅ 1 - 1 [parens are finished]
14 - 2 - 100 - 1 [multiplication is finished]
-- we do the subtraction left to right, but here are the steps:
12 - 100 - 1
-88 - 1
-89</span>
Answer:
y=x+3
Step-by-step explanation:
the line crosses the x axis at -3, this means you would do y=x-(-3) for the equation, therefore y=x+3
Answer:
B. f(x) =-150+1500
Step-by-step explanation:
Let x represents the number of months and y represents the savings account balance ( in dollars )
Thus, table would be,
x 0 2 4 6
y 1,500 1,200 900 600,
Let the linear function that represents the above table is,
y = mx + c
By the table,
1500 = m(0) + c ⇒ c = 1500,
Again by the table,
1200 = m(2) + c
1200 = 2m + 1500
-300 = 2m ⇒ m = -150
The function would be,
y = -150x +1500
Since, 900 = -150(4) + 1500
600 = -150(6) + 1500
The whole table satisfy the equation y = -150x +1500,
Hence, the linear function that models the given table is,
y = -150x +1500
Option 'B' is correct.
