elena55 [62]

The total cost of the lease would be $17,200. This is because $300 payment for 24 months is equal to $7,200 + $1,000 (down payment) and + the residual value of $9,000 = $17,200.

postnew [5]

Answer:

The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level

Step-by-step explanation:

Given that in a study of the accuracy of fast food drive-through orders, one restaurant had 34 orders that were not accurate among 371 orders observed.

Sample proportion $p=0.092\\q=1-p = 0.908\\n = 371$

$H_0: p =0.10\\H_a: p \neq 0.10$

(Two tailed test at 5% significance level)

p difference = $0.092-0.100\\=-0.0084$

Std error if H0 is true = $\sqrt{\frac{0.1(0.9)}{371} } \\=0.016$

Test statistic Z = p diff/std error

=0.539

p value = 0.5899

Since p > 0.05 accept null hypothesis

The claim that he rate of inaccurate orders is equal to 10% is supported by statistical evidnece at 5% level

Please answer question 10

sveta [45]

Answer:

Step-by-step explanation:

1) First, we figure out the number of blue and green marbles (27 each)

2) Subtract the 6 blue and 3 green marbles. We now have 21 blue marbles and 24 green marbles.

3) Since we want to have more blue marbles while taking out the <em>minimum</em> number of green, we're going to take out green marbles out until there's one less than blue. Because there's 21 blue, we want 20 green. We've taken out 4/13 marbles so far.

4) Now, we're going to take 1 marble out of both the greens and blues until we have 17 blue and 16 green. We've now taken out 12/13 marbles. We can't make the 13th marble a blue one, otherwise we even them out, so we'll take another green. Now we have 17 blue and 15 green.

5) Count the number of greens you've taken out, and voila!

You launch a water balloon. The function h=-0.08t^2+1.6t+2 models the height h (in feet) of the water balloon after t seconds. W

stellarik [79]

Answer:

The initial height of the balloon is 2 feet.

Step-by-step explanation:

The height of the balloon in feet after t seconds is given by the following equation:

$h(t) = -0.08t^{2} + 1.6t + 2$

What is the initial height of the balloon?

This is h when t = 0, that is, h(0). So

$h(0) = -0.08*0^{2} + 1.6*0 + 2 = 2$

The initial height of the balloon is 2 feet.
