Answer:
✅On average Albany gets 20.967 inches rain pee year and Zachary gets 25.153 inches rain per year.
✅On average, it rains more in Zachary in a year.
Step-by-step explanation:
Mean annual rainfall on average = total amount of rainfall for the period of years ÷ 10
✔️Mean Annual rainfall for Albany (in.):
= (22.82 + 19.83 + 28.40 + 23.35 + 30.78 + 21.34 + 11.20 + 17.04 + 18.63 + 16.28) ÷ 10
= 20.967
✔️Mean Annual rainfall for Zachary (in.):
= (26.41 + 23.54 + 30.02 + 26.35 + 34.24 + 25.74 + 18.98 + 21.26 + 23.61 + 21.38) ÷ 10
= 25.153
✅Therefore, on average Albany gets 20.967 inches rain pee year and Zachary gets 25.153 inches rain per year.
✅On average, it rains more in Zachary in a year.
Answer:
y = -1/2x + 13/2
Step-by-step explanation:
The slope of a line that is perpendicular to a line will be a negative reciprocal. When you rewrite 2x-7=8 into slope-intercept form, you get y=2x-8. The negative reciprocal of the slope 2x is -1/2x. There is only one option with this slope. If you're still not sure then you can use a graphing calculator to check this. An online one would be desmos
Answer:
C, between 3 and four hours.
Step-by-step explanation:
The y-axis is where we will find the number of chairs he makes, so we look there for 30. It isn't there, BUT, there is 32 and 24. Between 32 and 24 chairs, it lands between 3 and 4 hours. Hope this helps!
So we know that x+y+<1(the one that is not labeled or doesn't have a number)=180 degrees.
We also know that x+y= 98 degrees.
<1 and 98 degrees are supplementary. so <1=82 degrees.
We know that the triangle is isosceles so y=82 degrees as well.
We also know that a traingle =180 degrees so x=16 degrees
