Answer:

Step-by-step explanation:

The solution space is all the points to the right of the dotted line. Points ON the dotted line are not part of the solution (because dotted means excluding points on the line).

Example of points could be (0, 6), (3,0), (4,4), there is no limit to the number of solution points.

How do you factor the sum of 2 squares?

Kazeer [188]

<span>If two terms in a binomial are perfect squares separated by subtraction, then you canfactor them. To factor the difference of two perfect squares, remember this rule: if subtraction separates two squared terms, then the sum and the difference of the twosquare roots factor the binomial.</span>

Jonah invests $400in a bank account that pays 3.5% simple interst per year. At the end of each year Jonah spends 3/5 of the inte

Paraphin [41]

Answer:

$5.60

Step-by-step explanation:

interest = 3.5% = 3.5 ÷ 100 = 0.035

So 3.5% of $400 = 0.035 x 400 = $14

If Jonah spend 3/5 of the interest, then he gives his brother 2/5 of the interest each year.

2/5 of $14 = 2/5 x 14 = $5.60

Law Incorporation [45]

Answer:

Check the explanation

Step-by-step explanation:

The null and alternative hypotheses in symbols and words are as follows:

: p ≤ 0.06 (There has been no change in the contribution rate due to addition of the mailing labels)

: p > 0.06 (The addition of the mailing labels has increased the contribution rate)

Test Statistics

The following information is provided: The sample size is N = 75000, the number of favorable cases is X = 5625, and the sample

The z-statistic is computed as follows:

- $P_0$ (1 -

Test statistic z = 17.297

P-value

P-value corresponding to z = 17.297 for a two tailed test is obtained using standard normal table.

p-value = 0.0000

90% Confidence Interval Calculation

Kindly check the attached image below.

Conclusion

Since p-value = 0.0000 < α = 0.05, we reject null hypothesis .

At 0.05 significance level, there is enough evidence to conclude that the addition of the mailing labels has increased the contribution rate.

Since the 90% confidence interval (0.073, 0.077) does not contain the hypothesized value 0.06, the result is significant and we reject null hypothesis.

In other words, at 0.10 significance level, there is enough evidence to conclude that the addition of the mailing labels has increased the contribution rate.
