Agency leadership is very interested in trend analysis. Using the 750 randomly selected vehicles as their sample, data was collected to determine which vehicles currently meet or exceed fuel economy standards and which vehicles currently do not meet fuel economy standards. This information is found in the Meet or Not Meet Current Standards column. Agency leadership asks your team to construct a 95% One-Sample proportion confidence interval for the population proportion of all vehicles that meet current fuel economy standards. Assume that all necessary Central Limit Theorem conditions for a One-Proportion confidence interval have been met. What is the 95% lower limit?
Answers
Using the z-distribution, as we are working with a proportion, considering that the estimate is of 90%, the 95% lower limit is of 0.8785.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have that:
There is a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex]. We suppose an estimate of [tex]\pi = 0.9[/tex].The sample size is of n = 750.Hence, the lower bound of the interval will be given by:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.9 - 1.96\sqrt{\frac{0.9(0.1)}{750}} = 0.8785[/tex]

Determine the area of the composite figure.
Answers
Answer:
Area = 142.5 square inches
Step-by-step explanation:
So your shape is kind of a little house. The bottom part is a rectangle 9 × 9.5. The area of the rectangle is
Area = length×width
= 9 × 9.5
= 85.5
The "roof" of the little house is a triangle. The area of a triangle is 1/2×base×height
Now, the base of the "roof" is the same as the floor of the house, 9.5 inches.
The height of the whole thing is 21 inches. If we take away the rectangle's wall-height, we'll get the height of the "roof".
Roof height= 21 - 9
= 12 inches
Area_roof
=1/2 × base × height
=1/2 × 9.5 × 12
= 57 square inches
Total area is bottom plus roof (the rectangle and the triangle)
Total Area
= 85.5 + 57
= 142.5 sq in

Answer:
4. m<3 = 120
5. m<4 = 13
6. m<2 = 70
7. m<1 = 115
Step-by-step explanation:
4. m<3 = 120, this is because it is the same as m<1 due to vertical (congruent) angles
5. m<4 = 13, this is because it is the same as m<2 due to vertical (congruent) angles
6. m<2 = 70, this is because m<2 and m<3 are supplementary (adding up to 180) so we would subtract 180 - 110 (aka m<3) = 70 (aka m<2)
7. m<1 = 115, this is because m<1 and m<4 are supplementary (adding up to 180) so we would subtract 180 - 65 (aka m<4) = 115 (aka m<1)

[tex]4D + 6 + 2D = 6D + 6 = 2(3D + 3)[/tex] <--- A is correct
[tex]4D + 6 + 2D = 6D + 6 = 6(D +1)[/tex] < --- B is NOT correct
[tex]4D + 6 + 2D = 6D + 6 = 3d + 3d + 3 + 3 = (3d + 3)+(3d +3)[/tex] by associative and commutative properties
so C is correct
A and C are both correct.
Answer:
Choices A and C
Step-by-step explanation:
Start by simplifying the original expression.
4d+6+2d
Combine like terms
6d+6
Now, we can check each expression to see if it is equivalent to 6d+6
Choice A:
2(3d+3)
Distribute the 2
2(3d)+2(3)
6d+6 --> It is equivalent!
Choice B:
6(d+6)
Distribute the 6
6(d)+6(6)
6d+36 --> No, it is not equivalent
Choice C
(3d+3)+(3d+3)
The parentheses aren't necessary so we can take them out.
3d+3+3d+3
Combine like terms
6d+6 --> It is equivalent!

What is area of a geometric shape?The area of a two dimensional shape is the space enclosed by the boundary of the shape. The area of a rectangle is the product of its length and breadth, the area of a circle is π×(radius)².
Given that, the shorter side of a rectangle is 4cm.
Let the length of the longer side of the rectangle is x.
Then, the area of rectangle is 4x
Also, the sum of area of rectangle and a quarter circle is 33.4cm²
And the radius of quarter circle = shorter side of rectangle
Therefore, area of quarter circle = (1/4)×π(4)²
According to question,
4x + (1/4)π(4)² = 33.4
4x + 4π = 33.4
4x = 33.4 - 4×3.14
4x=20.84
x=5.21
Hence, the longer side of rectangle is 5.21 cm when the shorter side is 4cm and a quarter circle is drawn onto the shorter side of the rectangle.
