Answer:
Null hypothesis: ∪ = No possible child abuse or neglect
Alternative hypothesis: Uₐ = Possible child abuse or neglect
Step-by-step explanation:
Null hypothesis: ∪ = No possible child abuse or neglect
Alternative hypothesis: Uₐ = Possible child abuse or neglect
A type I error occurs when you reject the null hypothesis when it is true. In this situation, a type I error occurs when you conclude on possible child neglect or abuse and place the child in protective custody
A type II error occurs when you accept the null hypothesis when it is false. In this instance, a type II error occurs when you conclude on no possible child abuse or neglect when there is and fail to remove the child from the home.
In this case, the type II error is the more serious error. Failure to remove the child when there is possible child abuse or neglect will lead to more detrimental effect. Although, the type I error is also serious, it is not so detrimental as the type II error.
Area of square
= 7x7
=49
Area of triangle
=0.5x 7x12
=42
Total area of figure
=49+42
=91
Hence, answer is D
Answer:
2
Step-by-step explanation:
the y-intercept is where the line meets the y-axis
Step-by-step explanation:
you did not show us the picture or described what the shaded area is.
I assume it is the area of the circle without the inner square (as the "rectangke" is actually a square, because its sides are equally long).
so, we need to calculate the area of the circle and subtract the area of the square.
the area of the square is 3×3 = 9 cm².
the area of the circle is
pi×r²
with r being the radius.
so,
pi×4² = pi×16 = 16pi
the shaded area is then
16pi - 9 = 41.26548246... cm² ≈ 41.27 cm²
nothing of the answer options seems to be in that area, so maybe my assumption about the shaded area is wrong. or the specified answer options are mistyped. or both.
anyway, without additional information that is the best I can do.
