Need help solving the puzzle
1 answer:
Let gift box be x and the Christmas tree be y.
<u>Then:</u>
The equation formed by plugging x in place of gift box and christmas tree will be:
(1) 2x + y + 3 = 16
➛ 2x + y = 13
(2) 3x + y + 1 = 14
➛ 3x + y = 13
Subtracting (2) from (1), And we get:
➛ 3x + y - 2x - y = 0
➛ x = 0
Then, y = 13
<u>We </u><u>need </u><u>to </u><u>find:</u>
• yx + x
= 13 × 0 + 0
= 0
<u>Hence</u><u>:</u><u>-</u>
- The cost of all the items will be 0. Congrats for Christmas Bingo!!!

Answer:
option f is right
Step-by-step explanation:
Given that data is collected to perform the following hypothesis test.
(right tailed test)
Sample mean = 5.4
p value = 0.1034
when p value = 0.1034 we normally accept null hypothesis. i.e chances of null hypothesis true is the probability of obtaining test results at least as extreme as the results actually observed during the test, assuming that the null hypothesis is correct
f) If the mean µ does not differ significantly from 5.5 (that is, if the null hypothesis is true), then the probability of obtaining a sample mean y as far or farther from 5.5 than 5.4 is .1034.
.
