Which of the following is true?

Mathematics
1 answer:
VARVARA [1.3K]3 years ago
8 0

Answer:

The correct option is c which is if this test was one-tailed instead of two-tailed, you would reject the null.

Step-by-step explanation:

a: This statement cannot be true as the p-value for a 1 tailed test is dependent on the level of significance and other features.

b: This statement cannot be true as there is no valid mathematical correlation between the p-value of the one-tailed test and the current p-value.

c: This statement is true because due to the enhanced level of significance, the null hypothesis will not be rejected.

d: This statement is inverse of statement c which cannot be true.

e: The statement cannot be true as there is no correlation between the current p-value and the p-value of 1 tailed test. The correlation exists between the values of one-tailed and two-tailed p-values.

Answer:

Graph C

Step-by-step explanation:

y = .7x

For a direct variation, we know that the line has to go through the origin (0,0)

This eliminates graphs b and d.   We also know that the slope is .7

When x = 1, y = .7.  This eliminates graph a, because when x=1 y =1.  This leaves us graph c

In the parallelogram ABCD, M angle A =2x +50 and m angle C= 3x + 40. The measure of ZA is
ipn [44]

Answer:

∠A = 70°

Step-by-step explanation:

I'm... guessing this is what you mean? It would've been helpful if you'd provided pictures.

Since all parallelograms consist of two pairs of vertically opposite angles, ∠A and ∠C are equivalent.

Which means that 2x + 50 = 3x + 40.

In which you solve the equation.

2x + 50 = 3x + 40

-2x           -2x

50 = x + 40

-40  -40

x = 10

Now, to find ∠A, substitute x into the equation:

∠A = 2x + 50

x = 10

∠A = 20 + 50

∠A = 70

Hence, ∠A = 70°

The perimeter of a rectangle is 90 feet. The width is 15 feet. What is the perimeter?
lions [1.4K]
Length of the rectangle
=
15
feet
Breadth of the rectangle
=
30
feet.
Explanation:
Let the breadth of the rectangle
=
x
So, the length of the rectangle
=
2
×
x
The perimeter given
=
90
feet
As per the formula for perimeter of a rectangle
Perimeter
=
2
×
(length + breadth )
90
=
2
×
(
x
+
2
x
)
90
=
2
×
(
3
x
)
90
=
6
x
x
=
90
6
x
=
15
So the length of the rectangle
=
15
feet, breadth of the rectangle
=
30
feet.
