A streaming music site changed its format to focus on previously unreleased music from rising artists. The site manager now want

nika2105 [10]

Answer:

D) The manager should fail to reject the null hypothesis; there is not enough evidence to conclude that the number of unique daily listeners has changed.

Step-by-step explanation:

The scenario indicates the null hypotheses and alternative hypotheses are

Null hypotheses: The number of unique daily listeners hasn't changed.

Alternative hypotheses: The number of unique daily listeners has changed.

The null hypothesis is rejected if the calculated p-value is less significance level.

We are given that p-value is 0.0743 and confidence level=0.95.

Significance level =α=1-0.95=0.05.

As we can see the p-value is greater than significance level, so, we fail to reject the null hypotheses at 5% significance level.

Thus, we conclude at the 95% confidence level that the manager should fail to reject the null hypothesis; there is not enough evidence to conclude that the number of unique daily listeners has changed

(5a^2+6a+2)-(7a^2-7a-5)

krok68 [10]

For this case we must simplify the following expression: $(5a^ 2 + 6a + 2) - (7a^ 2-7a-5) =$

We eliminate the parentheses taking into account that:

$- * + = -\\- * - = +$

So:

$5a ^ 2 + 6a + 2-7a ^ 2 + 7a + 5 =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

$5a ^ 2-7a^2 + 6a + 7a +2 +5 =\\-2a ^ 2 + 13a + 7$

Answer:

$-2a ^ 2 + 13a + 7$
