Answer:
y = -2x + 9
Step-by-step explanation:
The general shape of the equation is y = ax + b, you just have to find a and b.
b is simple, it is the y coordinate where the line crosses the y axis, i.e., b=9.
a is the slope of the line. This is the change in y when you take one step to the right. The change is -2.
Hence y = -2x + 9
Answer:
0.057
Step-by-step explanation:
To obtain the p value, we need to obtain the test statistic :
For a one sample test :
Test statistic is given by :
(xbar - μ) ÷ (σ/√(n))
(185 - 175) ÷ (20/√(10))
10 ÷ 6.3245553
Test statistic = 1.581
Qe used the Z distribution because we are working with the population standard deviation.
Using the Pvalue from test statistic calculator :
Pvalue obtained using the Pvalue from Z statistic calculator, we obtain ;
Pvalue = 0.0569
The gross income is $85,463
Here are the deduction before tax is applied:
<span>$896 - income
</span>$2,145 - charitable donations
<span>$3,473 - medical expenses
2 x </span><span>$3,650 - exemptions
Adding all the deductions:
</span>$896 + $2,145 + $3,473 + 2 x $3,650 = $13,814
Subtracting this from the gross income:
$85,463 - $13,814 = $66,129
