Answer:

y = (C -0.99n)/48

Step-by-step explanation:

Undo what is done to y, in the reverse order. We have y multiplied by 48 then added to 0.99n. So, we must add the opposite of 0.99n and multiply that result by the reciprocal of 48.

C = 48y + 0.99n . . . . . . given

C - 0.99n = 48y . . . . . . add -0.99n

(C -0.99n)/48 = y . . . . . multiply by 1/48

Anon25 [30]

Answer:

The margin of error (E) $=0.49$

Step-by-step explanation:

Given,

mean $\bar{x}=6.88$

standard deviation $\sigma=1.90$

sample size $n=41$

$90\% \quad \text{confidence interval}$

Critical value $=\frac{z_\alpha}{2}\quad \quad\quad[\because\;\alpha=1-\text{confidence interval}]$

$=1-0.90$

$\Rightarrow \alpha=0.1$

Critical value $=\frac{z_{0.1}}{2}$

$=z_{0.05}$

$=1.645$

The margin of error (E) $=\frac{z_\alpha}{2} \times\frac{\sigma}{\sqrt{n} }$

$=1.645\times\frac{1.90}{\sqrt{41} }$

$=0.49$

Hence, The margin of error (E) $=0.49$

What is the sum of the polynomials?

Nadya [2.5K]

For this case we have the following polynomials:

$-x ^ 2 + 9\\-3x ^ 2 - 11x + 4$

Adding the polynomials we have:

$(-x ^ 2 + 9) + (-3x ^ 2 - 11x + 4)$

Rewriting we have:

$x ^ 2 (-1-3) - 11x + (9 + 4)$

Therefore, the result of the sum is:

$-4x ^ 2 - 11x + 13$

Answer:

the sum of the polynomials is:

$-4x ^ 2 - 11x + 13$

out of a group of zebras 6/5 times the square root of the number of zebras are playing on the shore of the tank remaining six ar

MatroZZZ [7]

Answer:

Step-by-step explanation:

(6/5)√x = x - 6

(36/25)x = x² - 12x + 36

0 = x² - 13.44x + 36

x = (13.44 ± √(13.44² - 4(1)(36))) / (2(1))

x = (13.44 ± 6.052569702...) / 2

x = 3.69371... zebras

x = 9.74628... zebras

In either case we have some odd fractions of zebras hanging around. This makes me highly suspect that the question is misreported

Find the sticker price and dealer's cost for the Tarop Series car. The base price given is $24,990.00. The options for the Tarop

podryga [215]

Alright, lets get started.

The base price is given : $ 24990

The dealer pays 76% of the base price means

he pays for base price : $24990 * \frac{76}{100}$

he pays for base price : $ 18992.4

For options, total : $868 + 452 + 1260 = 2580$

He pays 88% for options, means

he pays for options : $2580 * \frac{88}{100}$

he pays for options : $ 2270.4

So, total dealer pays : $18992.4 + 2270.4 +$ destination charges

So, total dealer pays : $18992.4 + 2270.4 + 630 =$ $ 21892.8

Hence dealer's cost : $ 21892.8

Price of sticker will be : $24990 + 868 + 452 + 1260 + 630$

Price of sticker will be : $ 28200

dealer's cost : $ 21892.8

Hope it will help :)
