Solve for x. 25 - 3x = -5(1 - x) - 2x
grandymaker [24]

Answer:

x = 5

Step-by-step explanation:

25 - 3x = -5(1 - x) - 2x

<u></u>

<u>We have to first get rid of the parenthesis:</u>

-5 * 1  ==>  -5

-5 * -x  ==>  5x

<u>So now you should have:</u>

25 - 3x = -5 + 5x - 2x

<u>Combine like terms:</u>

25 - 3x = -5 + 5x - 2x

25 - 3x = -5 + 3x

<u>Add 3x to both sides:</u>

25 - 3x  =  -5 + 3x

    + 3x  =      + 3x

<u>And you should have:</u>

25 = -5 + 6x

<u></u>

<u>Add 5 to both sides:</u>

25 = -5 + 6x

+5 = +5

30 = 6x

<u>Divide 6 to both sides:</u>

\frac{30}{6}     =      \frac{6x}{6}

5 = x

Assume that body masses of Goldfinch birds follow a normal distribution with standard deviation equal to 0.04 oz. An ornithologi
il63 [147K]

Answer:

The formula to generate 70% confidence interval is: [\overline{x} - 0.013, \overline{x} + 0.013], in which \overline{x}  is the sample mean.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.7}{2} = 0.15

Now, we have to find z in the Z-table as such z has a p-value of 1 - \alpha.

That is z with a pvalue of 1 - 0.15 = 0.85, so Z = 1.037.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

Assume that body masses of Goldfinch birds follow a normal distribution with standard deviation equal to 0.04 oz.

This means that \sigma = 0.04.

Sample of 10 birds:

This means that n = 10.

The margin of error is of:

M = z\frac{\sigma}{\sqrt{n}}

M = 1.037\frac{0.04}{\sqrt{10}}

M = 0.013

The lower end of the interval is the sample mean of \overline{x} subtracted by M.

The upper end of the interval is the sample mean of \overline{x} added to M.

Then, the formula to generate 70% confidence interval is: [\overline{x} - 0.013, \overline{x} + 0.013], in which \overline{x}  is the sample mean.

Hi! Does any one know how to do proportions? If so can you please help me out with these 2 problems? please show work on how you
Nataly [62]
Answers:

1.) 18 lemons
2.) 80 minutes

Explanation:

Porportions are a lot like fractions. For the first question, you can make the fraction 6/8, or 3/4 simplified. This means that for every 8 cups of water, you need 6 lemons.

Then, to find the amount of lemons you need if you have 24 cups of water, you need to think about what×8= 24. If we divide 24 by 8, we get 3, so if we multiply our fraction by 3/3, we should get the answer.

If we do 6/8 × 3/3, we get 18/24. This means that we need 18 lemons if we were to use 24 cups of water.

For the next question, our fraction 15/60, for 15 cakes baked in 60 minutes. Now we need to divide 20 cakes by 15.

This question is a little different from the first one because there will be a decimal involved. If we do 20/15, we get 1⅓. This means that this time, we will multiply 15/60 by (1⅓)/(1⅓).

If we multiply 60 by 1⅓, we get 80, which is the number of minutes needed to bake 20 cakes.

Hope this helps :)
