7 video games were in each case.
Step-by-step explanation:
-So, Ricardo has 2 cases of video games with the same amount of games per case.
-He gives 4 games to his brother and is left off with 10 games.
Add 10+4 to get the total amount of games.
Since there are 2 cases, divide the total amount of games (14) by the total amount of video game cases.
This gets us 7, which is the starting amount of video games in each case.
Answer:
y=2.50+175*(x-1)
$4727.50
Step-by-step explanation:
y=2.50+175*(x-1)
The first km costs 2.50 which is why you add it. You do x-1 because the 175 is charged for each additional km. So, if you traveled one km it would cost 2.50.
y=2.5+175*(28-1)
y=2.5+175*27
y=2.5+4725
y=$4727.50
Answer:
D. 65 degrees
Step-by-step explanation:
If two sides are congruent the corresponding angles are also congruent
Answer:
(x - 5)² + (y + 7)² = 81
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (5, - 7) and r = 9, thus
(x - 5)² + (y - (- 7))² = 9², that is
(x - 5)² + (y + 7)² = 81 ← equation of circle
Answer:
0.0656
Step-by-step explanation:
For each message, we have these following probabilities:
90% probability it is spam.
10% probability it is legitimate.
Compute the probability that the first legitimate e-mail she finds is the fifth message she checks:
The first four all spam, each with a 90% probability.
The fifth legitimate, with a 10% probability.
