1) idk I got none of your options
2)p=42,000÷(1+0.0225÷12)^(12×5)
P=37,535.04
3)PVAO=4900*12[(1/0.029)-(1/0.029*(1+0.029)^10]=504145.41..compare with 500000
So the answer is D
4)lucas
90×87.92=7,912.8
((8,476.20−7,912.8)
÷7,912.8)×100=7.1%

55×72.03=3,961.65
((4,192.10−3,961.65)
÷3,961.65)×100=5.8%
So the answer is D

Pavlova-9 [17]

Answer:

74.71%

Step-by-step explanation:

To calculate the experimental probability of the next scoop that they sell being vanilla, we need to divide the amount of scoops of ice cream that were vanilla (65 scoops) by the total amount of scoops of ice cream sold (87 scoops):

Probability of next scoop being vanilla = 65 / 87 = 0.7471 = 74.71%

The experimental probability of the next scoop they sell being vanilla is 74.71%.

-6 = x/8 + 4 1.8 16 -80 -16

kumpel [21]

Answer:

x = - 80

Step-by-step explanation:

Given

- 6 = $\frac{x}{8}$ + 4 ( subtract 4 from both sides )

- 10 = $\frac{x}{8}$ ( multiply both sides by 8 )

- 80 = x

$\frac{-6xy^{3}z^5}{-36x^{2}y^{2}z^4}$

First cross out the -6 and -36. Six will go into 6 one time and 6 will go into -36 six times so we have the following after crossing out.

$\frac{-6xy^{3}z^5}{-36x^{2}y^{2}z^4}$
$\frac{xy^{3}z^5}{6x^{2}y^{2}z^4}$ <---After crossing out

Next cross out the x / x^2 which will give us the following:
$\frac{xy^{3}z^5}{6x^{2}y^{2}z^4}$
$\frac{y^{3}z^5}{6xy^{2}z^4}$ <---After crossing out

Now cross out the y^2 / y^3
$\frac{y^{3}z^5}{6xy^{2}z^4}$
$\frac{yz^5}{6xz^4}$ <----After crossing out

All that is left is to cross out the z^5 / z^4 and we are done.
$\frac{yz^5}{6xz^4}$
$\frac{yz}{6x}$ <----After crossing out and we are done.

$\frac{-6xy^{3}z^5}{-36x^{2}y^{2}z^4} = \frac{yz}{6x}$
