I need options but so you know which one it is: it is the one with a number followed by an x (or it could just be x)
Hope this helps :)
<span>Given Equation: 2a − 5d = 30
Solution:
2a - 5d = 30
-5d = 30 -2a
d = ( 30 - 2a )/ (-5)
= -6 + (2a/5)
= (2a/5) - 6
I hope this helps</span>
Answer:
1. 8.576%
2. Yes
Step-by-step explanation:
1. Use the calculator
Enter: normalcdf(8, E99, 0, 5.9)
This is equal to .08756.
Convert this number into a percent = 8.756%
2.
First, calculate the residual
Residual = Observed - Predicted = 165 - 2.599(20) + 105.08 = 7.94
Use the calculator
Enter: normalcdf(7.94, E99, 0, 5.9)
This is equal to .0892.
Convert this number into a percent = 8.92%
This would be surprising, because the chance of this happening is very low.
Answer:
29°
Step-by-step explanation:
151° + a=180°
We know the sum of angles in a straight line is 180°
a= 180°-151°
The sign changed as it changed sides
a= 29°
Find the difference in gallons and the difference in the weights
46 - 12 = 34 gallons
2399 - 2176 = 223 pounds
so 34 gallons of gas weighs 223 pounds
find weight per pound: 223 pounds / 34 gallons = 6.5588 pounds per gallon
round to 6.6 pounds per gallon
54 gallons - 46 gallons = 8 gallons
8 gallons x 6.6 pounds per gallon = 52.8 pounds, round to 53 pounds
2399 + 53 = 2452 weight of plane with 54 gallons
