Factorize the following expressions

ValentinkaMS [17]

Answer:

6) b(3a^4-5c³)

7) 3x³yz(2x+5y)

8) 4a²b²c³(2bc-3a)

9) 4xy(2y+7z-1)

10) 2mn(5n²+2m-3n)

Step-by-step explanation:

6) Factor out the b and you get b(3a^4-5c³)

7) Factor out the 3x³yz and you get 3x³yz(2x+5y)

8) Factor out the 4a²b³c³ and you get 4a²b²c³(2bc-3a)

9) Factor out the 4xy and you get 4xy(2y+7z-1)

10) Factor out the 2mn and you get 2mn(5n²+2m-3n)

A researcher conducts a repeated-measures study to evaluate a treatment with a sample of n = 16 participants and obtains a t sta

Sedaia [141]

Answer:

Option 3) We reject the null hypothesis with one tail test and accept the null hypothesis with two tail test.

Step-by-step explanation:

We are given the following information:

n = 16

$t_{statistic} = 1.94$

$\alpha = 0.05$

Now,

Right One-tail Test

$t_{critical} \text{ at 0.05 level of significance, 15 degree of freedom } = 1.753$

$t_{stat} > t_{critical}$

We reject the null hypothesis in this case.

Two-tail Test

Now, $t_{critical} \text{ at 0.05 level of significance, 9 degree of freedom } = \pm 2.131$

$-2.131 < t_{stat} < 2.131$

We accept the null hypothesis in this case.

Option 3) We reject the null hypothesis with one tail test and accept the null hypothesis with two tail test.
