Answer:
7. Ten days were above 70 degrees
8. Approximately 33% of the days were 69 degrees or lower
9. Approximately 8 days would most likely be above 80 degrees
Step-by-step explanation:
The very first thing I did is I put the values in order, ranging from 66 to 85. Then, I counted the number of days where the high temperature was greater than 70 degrees (which ended up being 10).
Five of the days were 69 degrees or lower, so I divided that by fifteen to get 33.33333% (which you can round down as 33%).
Then, as four of these fifteen days had temperatures greater than 80 degrees, I divided four by fifteen and got approximately 26.7%. Multiplying 30 by 0.267, I get 8.01 (which you can just round down as 8).
Answer:
17/50
Step-by-step explanation:
P(red or purple) = number of red or purple / total
There are 7 red rings and 10 purple rings
= (7+10) / 50
= 17/50
Answer: They can order from 0 to 449 bars, but no more.
Step-by-step explanation:
Given: The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20.00 for shipping regardless of the size of the order. The band must spend less than $200.00 on bars for the fundraiser.
The inequality below relates x, the number of bars that could be ordered, with the shipping costs and their spending requirements.
To solve for x, subtract 20 on both sides, we get
Divide 0.40 on both sides, we get
......... → the number of bars that could be ordered, with the shipping costs and their spending requirements must less than 450.
Thus, they can order from 0 to 449 bars, but no more.
Answer:
-4, -2, 0, 2
Step-by-step explanation:
the expression for the integers are; x, x +2, x + 4, x + 6
4x + 12 = -4
4x = -16
x = - 4
your integers are; -4, -2, 0, 2
if you add those your answer will be -4
Using TOA CAH SOH
You are given an angle and a length, in this case the lenth is adj to the angle.
∴ use TOA
tan(32) = f/18
f = 18tan(32)
f = 11.24764 units
f ≈ 11.25 units (2d.p.)
