Travels by 2 so therefore the answer is B
The correct answer is a || move the constant over (5x=-15-5), combine like terms (5x=-20), divide both sides by 5 to get x alone (x=-20/5), solve (x=-4) || please mark brainliest
2.25 + 0.59 + 6.49 + 1.49 = 10.82 dollars
10.82 - 5.25 = $5.57 is his total purchase
A)
10.00 - 3.55 = 6.45 back
a $5 bill and a $1 dollar bill = $6
a quarter and 2 dimes = 0.45
so 2 bills and 3 coins
B) 120 x 4 = 480 minutes
480/60 = 8 hours
Answer: P < 300 = 0.102
Step-by-step explanation:
Suppose the round-trip airfare between Boston and Orlando follows the normal probability distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = the round-trip airfare between Boston and Orlando.
µ = mean
σ = standard deviation
From the information given,
µ = $387.20
σ = $68.50
The probability that a randomly selected airfare between Boston and San Francisco will be less than $300 is expressed as
P < 300
For x = 300,
z = (300 - 387.20)/68.5 = - 1.27
Looking at the normal distribution table, the probability corresponding to the z score is 0.102
