Answer:
Step-by-step explanation:
f ( x ) = 3 x ^ { 3 } - 5 x ^ { 2 } + x - 2 g ( x ) = x + 2
Subtract 3x³ from each sides.
-5x^{2}+x-2gx=x+2-3x^{3}
Add 5x² to both sides.
x-2gx=x+2-3x^{3}+5x^{2}
Subtract x from both sides.
-2gx=x+2-3x^{3}+5x^{2}-x
Combine x and -x to get 0.
-2gx=2-3x^{3}+5x^{2}
The equation is in standard form.
\left(-2x\right)g=2+5x^{2}-3x^{3}
Divide both sides by -2x.
\frac{\left(-2x\right)g}{-2x}=\frac{2+5x^{2}-3x^{3}}{-2x}
Dividing bu -2x undoes the multiplication by -2x.
g=\frac{2+5x^{2}-3x^{3}}{-2x}
Divide 2-3x³ +5x² by -2x.
g=\frac{3x^{2}}{2}-\frac{5x}{2}-\frac{1}{x}
Answer:
(230.21 ; 233.13)
Step-by-step explanation:
Given the data :
230.66, 233.05, 232.58, 229.48, 232.58
To calculate the 90% CI
WE obtain the mean and standard deviation of the sample data :
Mean of sample, ΣX /n = 1158.35/5 = 231.67
The standard deviation of the sample, s = 1.531 (Using calculator).
(The 90% Tcritical value, 2 sided, df = 4) = 2.132
The confidence interval, CI :
Mean ± Tcritical * s/√n
C.I = 231.67 ± (2.132 * (1.531/√5)
C. I = 231.67 ± 1.4597
(231.67 - 1.4597) ; (231.67 + 1.4597)
(230.21 ; 233.13)
Quinn needs to save another $275.
<h3>How much more money does Quinn need to reach her goal for the year?</h3>
The money that she needs will be equal to the difference between the amount that she wants to save, and the amount that she already has.
- She wants to save $300.
- She already has $25
The difference is:
D = $300 - $25 = $275
This means that, to reach her goal this year, Quinn needs to save another $275.
