Let x = cost for a night. y = cost to rent car for a day.
Connor = 3 nights and 4 days = 3x + 4y = 675
<span>Jillian = 4 nights and 5 days = 4x + 5y = 875
3x + 4y = 675 Multiply by 5
4x + 5y = 875 Multiply by 4
</span>
5*3x + 5*4y = 5*675 15x + 20y = 3375
4*4x + 4*5y = 4*875 16x + 20y = 3500
<span>15x + 20y = 3375</span>
-
<span>16x + 20y = 3500
</span>________________
-x + 0 = -125
x = 125
The cost per night is x, = $125
Hey there! :)
Answer:
25 pieces.
Step-by-step explanation:
To solve for the amount of pieces that can be cut, we must divide fractions:
15 ÷ 3/5 = x
When dividing fractions, you must multiply by the reciprocal. Therefore:
Therefore, 25 pieces can be cut.
Answer: describe the data: mean=12, interquartile range=7, and range=17. Do not describe the data: range=23, median=10, and interquartile range= 12
Step-by-step explanation:
To work out the probability of both errors occuring, simply multiply the probability of the first error by the probability of the second error. Therefore the probability of both errors occurring is 0.2 * 0.3 = 0.06.
