Answer:
p value =0.544
Step-by-step explanation:
Given that in a survey, 33% of the respondents stated that they talk to their pets on the telephone.
(left tailed test at 1% level)
Sample proportion p =
Assuming H0 to be true, std error of proportion
=
p difference = -0.0233
Test statistic Z = p difference/std error
= -0.6067
p value = 0.544
Since p > alpha, we accept H0
Im gona assume you mean
f(x) = 3x + 2 + 8x + 4. Add like-terms
Y = 11x + 6
0= 11x + 6
-6 = 11x
X= -6/11
Answer:
624
Step-by-step explanation:
The sequence is 49, 47, 45,...., 7, 5, 3. This is an arithmetic sequence, because the difference between terms is the same.
The sum of the first n terms of an arithmetic sequence is:
S = n/2 (a₁ + an)
where a₁ is the first term and an is the nth term.
Here, we know that a₁ = 49 and an = 3. But we need to find what n is. To do that, we use definition of an arithmetic sequence:
an = a₁ + (n-1) d
where d is the common difference (in this case, -2)
3 = 49 + (n-1) (-2)
2(n-1) = 46
n - 1 = 23
n = 24
So there are 24 terms in the sequence.
The sum is:
S = 24/2 (49 + 3)
S = 12 (52)
S = 624
