Answer:

8.38 rounded to nearest hundredth

Step-by-step explanation:

2.14x-12.18=5.76

        +12.18=+12.18

use the inverse of subtraction which is adding .the 12.18 cancels out on the left side.

2.14x =17.94

now to get x by itself you divide 2.14 on both sides

x=8.38

Add 12.18 to 5.76
which leaves 2.14x = 17.94
divide both sides by 2.14
which leaves
X = 8.38318

Please help me w the equation and please don’t take advantage of the points.
svetoff [14.1K]

Answer:

y = 6x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 6 and given point (0, 4 ) ⇒ c = 4

y = 6x + 4 ← equation of line

Suppose a certain type of fertilizer has an expected yield per acre of mu 1 with variance sigma 2, whereas the expected yield fo
mart [117]

Answer:

See the proof below.

Step-by-step explanation:

For this case we just need to apply properties of expected value. We know that the estimator is given by:

S^2_p= \frac{(n_1 -1) S^2_1 +(n_2 -1) S^2_2}{n_1 +n_2 -2}

And we want to proof that E(S^2_p)= \sigma^2

So we can begin with this:

E(S^2_p)= E(\frac{(n_1 -1) S^2_1 +(n_2 -1) S^2_2}{n_1 +n_2 -2})

And we can distribute the expected value into the temrs like this:

E(S^2_p)= \frac{(n_1 -1) E(S^2_1) +(n_2 -1) E(S^2_2)}{n_1 +n_2 -2}

And we know that the expected value for the estimator of the variance s is \sigma, or in other way E(s) = \sigma so if we apply this property here we have:

E(S^2_p)= \frac{(n_1 -1 )\sigma^2_1 +(n_2 -1) \sigma^2_2}{n_1 +n_2 -2}

And we know that \sigma^2_1 = \sigma^2_2 = \sigma^2 so using this we can take common factor like this:

E(S^2_p)= \frac{(n_1 -1) +(n_2 -1)}{n_1 +n_2 -2} \sigma^2 =\sigma^2

And then we see that the pooled variance is an unbiased estimator for the population variance when we have two population with the same variance.

Damien has 30 coins, all nickels and dimes. The total value of all these coins is $2.05. How many nickels does he have?
Damm [24]

Hi there!

nickels:19

We know that there is only nickels and dimes in his coin collection..

<u><em>1.Multiply two terms:</em></u>

<u><em /></u>10<u><em>·</em></u>10=1.00<u><em /></u>

<u><em>Then there would be 20 nickels but 1+1=2 not 2.05.</em></u>

<u><em>2.Multiply the terms:</em></u>

<u><em /></u>11<u><em>·</em></u>10=1.10<u><em /></u>

<u><em /></u>19<u><em>·</em></u>5=0.95<u><em /></u>

<u><em>3.Combine the two terms:</em></u>

<u><em /></u>1.10+0.95=2.05<u><em /></u>

Therefore, there would be 19 nickels...

<u><em /></u>
