Answer:
True , null
Step-by-step explanation:
Mostly the true hypothesis is the null hypothesis .
We test the true hypothesis , the null hypothesis against the claim provided which is named as alternate hypothesis.
When the false hypothesis is the null hypothesis , type II error is made.
Confounded in statistics means when the alternative explanations cannot be eliminated.But we have the alternate hypothesis in hypothesis testing.
So option 1 is correct
The formula to find the area of this circle is:
A = pi(r^2)
A = 3.14(3.5^2)
A = 3.14(12.25)
A= 38.465 cm
Answer:
24
Step-by-step explanation:
the negatives cancel each other out
The value of the given functions as listed are 30.09 degrees, 86.16 degrees, 38.12 degrees, and 83.83degrees
Given the following expression
sin x = 0.5015
Taking the inverse of both sides
sin⁻¹(sinx) = sin⁻¹0.5015
x = sin⁻¹0.5015
x = 30.09 degrees
For the cos function
cos⁻¹(cosx) = cos⁻¹0.5015
x = cos⁻¹0.0670
x = 86.16 degrees
For the tan function
tan⁻¹(tanx) = tan⁻¹0.5015
x = tan⁻¹0.5015
x =38.12 degrees
For the tan function
tan⁻¹(tanx) = tan⁻¹9.254
x = tan⁻¹9.254
x = 83.83degrees
Hence the value of the given functions as listed are 30.09 degrees, 86.16 degrees, 38.12 degrees, and 83.83degrees
