We should first find the gas mileage
that will be 535/21 equals to 25.5
The car's gas mileage is 25.5
To find how much the car can drive on 51 gallons of gas
25.5×51
Equals to 1300.5
the car can drive 1300.5 miles on 51 gallons of gas
Answer:
It's blurry and can you please just write what it says?
The slope would be - 1/2 !!
you would number the x and y values of the coordinates.
( -2 , 5 ) ( -6 , 7 )
x1. y1. x2. y2
then do the formula that gives you the slope y2 - y1 / x2 - x1
this gives you:
7 - 5 / -6 - (-2) = 2/ -4 (simplify) -1/2
so this would give you m= -1/2
Answer:
Step-by-step explanation:
Given that in a rural area, only about 30% of the wells that are drilled find adequate water at a depth of 100 feet or less.
The sample size n = 80
no of wells less than 100 feet deep=27
Sample proportion = 
a) Create hypotheses as
(Right tailed test)
p difference 
Std error of p = 
b) Assumptions: Each trial is independent and np and nq >5
c) Z test can be used.
Z= p diff/std error = 
p value = 0.233
d) p value is the probability for which null hypothesis is false.
e) Conclusion: Since p >0.05 we accept null hypothesis
there is no statistical evidence which support the claim that more than 30% are drilled.
If you would like to find the solution of the system of equations, you can do this using the following steps:
x - 8y = 21 /*(-3)
3x - 8y = 15
______________
-3x + 24y = -63
<span>3x - 8y = 15
</span>______________
-3x + 24y + 3x - 8y = -63 + 15
16y = -48 /16
y = -48/16
y = -3
<span>x - 8y = 21
</span>x = 21 + 8y
x = 21 + 8 * (-3)
x = 21 - 24
x = -3
(x, y) = (-3, -3)
The correct result would be (-3, -3).
