okay I need help please
Step-by-step explanation:
find cos b in the triangle
Following the setps we have that
![\begin{gathered} n\cdot n=64 \\ n^2=64 \\ n=\sqrt[]{64}=8 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20n%5Ccdot%20n%3D64%20%5C%5C%20n%5E2%3D64%20%5C%5C%20n%3D%5Csqrt%5B%5D%7B64%7D%3D8%20%5Cend%7Bgathered%7D)
the lengths of the sides of the original square is 8 inches each one. Now we are going to find the lengths of the sides of the new square following the step 2
the lengths of the sides of new square is 12 inches each one.
Answer:
Yes, Yes, No, Yes.
Step-by-step explanation:
2/5 as a decimal = 0.4
4 ÷ 0.4 = 10
1 is correct.
2 x 10 = 20
2 is correct.
6 x 10 = 60
3 is incorrect.
10 ÷ 2 = 5
4 is correct.
A parallel line has the same slope as the original line. So in this case the slope of the line is also 3/4. Now how do we know if it intersects the point? We need to adjust the y intercept.
Currently, we know the equation of the line is y= 3/4 x + b, where b is the thing we are looking for. We also have a point, which supplies the x and y. Plug that in and solve for b
-2 = (3/4)*(12) + b
You'll get b= -11
So the equation of the parallel line intersecting the point given is y= 3/4x -11.
I am assuming that the slope is 3/4 based on the way you formatted the original equation, but it's the same steps if the slope is different.
Answer:
The correct answer is "664".
Step-by-step explanation:
The given values are:
Margin of error,
E = 5%
i.e.,
= 0.05
Level of confidence,
C = 99%
i.e.,
= 0.99
Level of significance,
α = 0.01
From the z value table,
Critical z = 2.576
As we know,
The required sample size n will be:
= 
On substituting the values, we get
= 
= 
= 
= 
i.e.,
=
