Answer: 98%
Step-by-step explanation:
In statistics , the P-value gives the significance level of the population parameter in the population.
The significance level is denoted by 
Level of confidence is given by :-
Given : The P-value is 0.02, then the significance level is 
which can be written as 2%.
Then, the confidence interval : 
i.e. 98%
Answer:
Step-by-step explanation:
What we're looking for here is the volume of this ball, which is the volume of a sphere:
If our diameter is 3, then the radius is 1.5:
In terms of π, the solution is
which can also be expressed as 
Or if you have to multiply in the pi, the solution is
V = 14.14 cubic inches
<span> -vp + 30 < 45 for v.
</span> -vp < 15
v > -15/p

Let:
Larger number = x
Smaller number = y
-------------------------------------------------------------------------------------------------------------------
x + y = 49
x - y = 21
-------------------------------------------------------------------------------------------------------------------
Isolate the x in the first equation. Subtract y from both sides
x + y (-y) = 49 (-y)
x = 49 - y
-------------------------------------------------------------------------------------------------------------------
Now that we know what x is, plug in 49 - y (which = x) into x in the other equation.
x - y = 21
(49 - y) -y = 21
Simplify.
49 -2y = 21
Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First subtract 49 from both sides
-2y +49 (-49) = 21 (-49)
-2y = 21 - 49
-2y = -28
Next, divide -2 from both sides to isolate the y
-2y/-2 = -28/-2
y = -28/-2
y = 14
-------------------------------------------------------------------------------------------------------------------
Now that we know what y is, plug into one of the equations.
x + y = 49
x + (14) = 49
Isolate the x. Subtract 14 from both sides
x + 14 (-14) = 49 (-14)
x = 49 (-14)
Simplify
x = 35
-------------------------------------------------------------------------------------------------------------------
Answer:
Larger number: 35
Smaller number: 14

Answer:
B
Step-by-step explanation:
We have to find which trinomial has:
1) two terms that are the perfect square of two numbers
2) a terms that is the double product of the two numbers
the first condition is satisfied by A and B, but only B satisfied the second., in fact the trinomial can be rewrite as: (2a-5)^2
Options C and D are traps because the square of a number can’t be negative
