Answer:
Step-by-step explanation:
we are given
We can factor it
we can use grouping method
now, we can take out common terms
we can take 2x+5 from both terms
so, we get factor terms as

Answer:
0.0930
Step-by-step explanation:
Given that one of your friends is testing the effect of drinking coffee on the duration of cold symptoms. The common cold lasts, on average, 6 days.
she tests a one-sided alternative about the population mean cold duration when drinking coffee, H0: μcoffee = 6 Ha: μcoffee < 6 She finds z = −1.68 with one-sided P-value P = 0.0465.
If hypotheses changed to two tailed as:
(Two tailed test)
Since we have mean difference and std error the same, test statistic would remain the same.
p value for two tailed would be = twice the p value for one tail
=
If you can't see the picture the answer is: (y+4)(y+2).
Hope this helps, and May the Force Be With You!
