Answer:

x^3 + x^2 + 4x - 20.

Step-by-step explanation:

I have assumed there is a + between the 3x and the 10.

f(x) * g(x)

= (x^2 + 3x + 10)(x - 2)

= x^3 + 3x^2 + 10x - 2x^2 - 6x - 20

= x^3 + x^2 + 4x - 20.

Every confidence interval has associated z value. As confidence interval increases so do the z value associated with it.
The confidence interval can be calculated using following formula:
$\overline{x} \pm \frac{zs}{\sqrt n}$
Where $\overline{x}$ is the mean value, z is the associated z value, s is the standard deviation and n is the number of samples.
We know that standard deviation is simply a square root of variance:
$s=\sqrt{315900.20}=\$562.05$
The confidence interval of 95% has associated z value of 1.960.
Now we can calculate the confidence interval for our income:
$3472.00\pm \frac{1.960\cdot 562.05}{\sqrt{60}}\\ \$3472.00\pm142.22$

What's

Iteru [2.4K]

Answer:

374/105.

Step-by-step explanation:

1/3 of 8 * 2/7

= 1/3 * 8 * 2/7

= 8/3 * 2/7

= 16/21.

2/5 of 7

= 2/5 * 7

= 14/5.

Adding 16/21 + 14/5

= 80 / 105 + (14*21) / 105

= 80/105 + 294/105

= 374/105.

Anastaziya [24]

Answer 
=3,075.36 ml

Explanation
We must first convert pounds to kilograms. 1Lbs = 0.453592Kg.
So, 226 Lbs=226×0.453592
=102.512Kg
Now calculate how many ml Mr. Rogers would take.
30ml→1 Kg
What about 102.512 Kg?
102.512Kg→102.512×30
=3,075.36 ml
Since this figure is above the threshold ml per day, then we take the answer as 3,075.36 ml per day.

Oh this is a great question. For future reference, the formula for this would be called an exponential growth or decay function, here it Is;
Y = a( 1+r )ˣ or Y = a( 1 - r )ˣ
the answer could be found by plugging your numbers into these equations
For example:
Y = 15,250 ( 1 - .075)⁶
A value = starting value of object
R value= decimal equivalent of percent increase or decrease
x value = number of years it has been
