Answer: (3.5,-2)
Step-by-step explanation:
To solve this problem, all we have to do is plug in y=-2 into either equations from step one to find the coordinate. To make sure we have the right x-coordinate, let's plug in y for both equations.
4x-7y=28 [plug in y=-2]
4x-7(-2)=28 [multiply]
4x+14=28 [subtract both sides by 14]
4x=14 [divide both sides by 4]
x=3.5
------------------------------------------------------------------------------------------------------------
6x-5y=31 [plug in y=-2]
6x-5(-2)=31 [multiply]
6x+10=31 [subtract both sides by 10]
6x=21 [divide both sides by 6]
x=3.5
Now, we know the solution to the system is (3.5,-2).
Answer:
The one tailed P-value for the test statistic for df = n-1 = 33-1 = 32 is
Step-by-step explanation:
We are given:
Claim: 
°F
Now we can use the technology like excel to find the P-value. The excel function is given below:
Where:
1.021 is the test statistic
32 is the degrees of freedom
1 stands for one tailed alternative hypothesis.
Therefore, the P-value is 0.1575
Answer:
So,
And,
But, given g(a) = 7
So, from 2nd and 3rd step,
3a-1=7
3a=6
Therefore, a = 2

Here we're dividing a fraction (5/8) by another fraction. We could obtain the same result by inverting the divisor (2/5) and then multiplying (5/8) by (5/2).
The product is 25/16.
Thus, 2/5 divides into 5/8 25/16 times, or 1 9/16 times.
