At the standard 0.05 value, this is not significant, however at a 0.01 level, it would be significant
I think it might be C but please wait for someone else to comment to confirm my answer :) have a beautiful day you are loved
Answer:
456.2 units²
Step-by-step explanation:
The area of the square base is ...
base area = w² = (10 units)² = 100 units²
The lateral area is 4 times the area of one rectangular face:
lateral area = 4wx = 4(10 units)(5 units) = 200 units²
The area of one triangular face is half the product of its base length (w) and its slant height (h). The latter is found using the Pythagorean theorem:
h² = y² +(w/2)² = (6 units)² +((10 units)/2)² = 61 units²
h = √61 units
So, the area of 4 triangles is ...
area of triangular faces = 4(1/2)wh = 2(10 units)(√61 units) ≈ 156.2 units²
__
Now we have the areas of the parts, so we can add them together to get the total surface area:
surface area = base area + lateral area + area of triangular faces
= 100 units² + 200 units² + 156.2 units²
surface area = 456.2 units²
Given:
The values of a linear function are
and
.
To find:
The linear function.
Solution:
If a linear function passes through two points, then the equation of the linear function is:

The values of a linear function are
and
. It means the function passes through the points (-9,8) and (0,1). So, the equation of the linear function is:




Adding 8 on both sides, we get


Putting
, we get

Therefore, the required linear function is
.
The answer is 7, 3 plus 1 equals 4 minus four equals zero plus 7= 7
