Answer:
The freelancer needs to calculate the value of the observed test statistic - average annual pay per click advertising cost - in order to compare with the critical value.
Step-by-step explanation:
His hypothesis test will be:
Null hypothesis: Average Annual Pay per click advertising cost is still less than 3300 dollars
(Note: the null hypothesis is the fact that the experimenter wishes to refute)
Alternative Hypothesis: Average annual pay per click advertising cost is now above 3300 dollars
(Alternative hypothesis is the fact that the experimenter expects to be true)
The Critical Value is a cutoff value for which if the value of the observed test statistic exceeds it, the null hypothesis is refuted and if the value of the observed test statistic is below it, the null hypothesis remains.
That is, either the freelancer accepts that the cost has not risen or he accepts that the cost has risen.
16 ounces = 1 pound
2x16 + 3 = 35
56 - 35 = 21
21 ounces
Answer:
2(x-9)(x+5)
Step-by-step explanation:
To construct a triangle, the sum of any 2 sides of the triangle should be greater than the third side of the triangle.
lets calculate the sums of all the given choices to find out which three lengths given do not form a triangle.
A.
6,10,18
6 + 10 = 16
16 is smaller than the third side-18
Therefore these 3 lengths do not form a triangle
B.10,12,15
10 + 12 = 22 15+12 = 27 15 + 10 = 25
22>15 (3rd side) 27>10 (3rd side) 25>12 (3rd side)
In this triangle, sum of all the possible pairs of sides are greater than the third side therefore these lengths can form a triangle
C.10,15,6
10 + 15 = 25 15 + 6 = 21 10+6 = 16
25 > 6 21>10 16>15
in this too, sum of all the possible pairs of sides are greater than the third side. These lengths can be used to form a triangle
D.10,18 ,12
10 + 18 = 28 18 + 12 = 30 10 +12 = 22
28> 12 30>10 22> 18
Therefore these lengths can also be used to form a triangle
correct answer is 6,10 and 18 these cannot form a triangle
If you do 220-40 then the second digit of the negative number will equal x.
