Answer:
t = -1.862, df = 399, p > 0.05
Step-by-step explanation:
The null hypothesis is the statement which is test for its validity. The decision to accept or reject the null hypothesis is based on the test statistics value. In the given question the null hypothesis is H0 = 34. There is one sample t-test for the testing of null hypothesis. The null hypothesis will be same for each type of one sample t-test. The null hypothesis assumes that the difference between the true mean and comparison value is zero.
The answer is 3.5 to the question
Answer: The tan 130° is expressed as 
Step-by-step explanation:
Since we have given that
As we know that
cos (π - θ ) = -cos θ
so, cos(180-50)=-cos 130° = -a
so, sin 130° would become
So, tan 130° is given by
Hence, the tan 130° is expressed as
Answer:
8a^3
Step-by-step explanation:
Given that;
2^x = a, we want an expression for 8^(x + 1)
we have this as;
8^(x + 1) = 8^x * 8^1
8^x = (2^x)(3)
8^x is thus same as 2^3x
So replace 2^x by a
Thus, we have a^3
Multiply this by the 8 we had initially; that will give;
8 * a^3 = 8a^3
Answer:
x=−1195/236
