3. Write an equation of the line that passes through (2, 3) and is perpendicular to y=-1/2x - 5
Answer:
y=2x-1
Step-by-step explanation:
A line that is perpendicular has a slope that is a negative reciprocal of the given equation. The slope of the given equation is -1/2, so the negative reciprocal would be 2.
Then, using slope-intercept form, plug in the point values (2,3) into the equation and solve for b.
y=mx+b
y=2x+b
3=2(2)+b
-1=b
Therefore the equation is y=2x-1

Find the Area of the figure below, composed of a rectangle with a semicircle
removed from it. Round to the nearest tenths place.
Answer:
Area of the figure = 25.7 units²
Step-by-step explanation:
Area of the given figure = Area of rectangle ABCD - Area of the semicircle with diameter CD
Area of the rectangle ABCD = Length × Width
= BC × AB
= 8 × 4
= 32 units²
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
Here, r = radius of the semicircle
r = [tex]\frac{\text{Diameter}}{2}[/tex]
r = [tex]\frac{1}{2}(CD)[/tex]
r = [tex]\frac{4}{2}[/tex]
r = 2 units
Therefore, area of the semicircle = [tex]\frac{1}{2}\pi (2)^2[/tex]
= 2π
= 6.28 units²
Area of the given figure = 32 - 6.28
= 25.72 units²
≈ 25.7 units²

Not Supported
Answer:
Over 300 students did not support start time after 8:00am
Step-by-step explanation:
Given
[tex]N = 600[/tex] --- population
[tex]n = 40[/tex] --- sample
See attachment for dataset
Required [True/False]
Over 300 wants start time after 8:00am
First, we calculate the number of samples that wants start time after 8:00am
[tex]x = 8:30am\ start + 9:00am\ start[/tex]
For sample 1
[tex]x_1 = 18[/tex]
The corresponding value of x1 in the overall population is:
[tex]X_1 = \frac{x_1}{n} * N[/tex]
[tex]X_1 = \frac{18}{40} * 600[/tex]
[tex]X_1 = \frac{18 * 600}{40}[/tex]
[tex]X_1 = \frac{10800}{40}[/tex]
[tex]X_1 = 270[/tex]
For sample 2
[tex]x_2 = 19[/tex]
The corresponding value of x2 in the overall population is:
[tex]X_2 = \frac{x_2}{n} * N[/tex]
[tex]X_2 = \frac{19}{40} * 600[/tex]
[tex]X_2 = \frac{19* 600}{40}[/tex]
[tex]X_2 = \frac{11400}{40}[/tex]
[tex]X_2 = 285[/tex]
None of X1 and X2 is greater than 300.
Hence, over 300 students did not support start time after 8:00am
None of X1 and X2 is greater than 300. so, over 300 students did not support start time after 8:00 am.
The population is 600 and the sample is 40.
What are Population Inferences?The population of inference refers to the population (or universe) to which the results from a sample survey are meant to generalize.
Over 300 students did not support start time after 8:00 am
For sample 1
[tex]\rm x_{1} =18\\[/tex]
The corresponding value of x1 in the overall population is:
[tex]\rm X_{1} =\frac{x_{1} }{n} \times N\\\rm X_{1} =\frac{18}{40} \times 600\\\rm X_{1} =\frac{10800}{40}\\ \rm X_{1} =270\\[/tex]
For sample 2
[tex]\rm x_{2} =19[/tex]
The corresponding value of x2 in the overall population is:
[tex]\rm X_{2} =\frac{x_{2} }{n} \times N\\\rm X_{2} =\frac{19}{40} \times 600\\\rm X_{2} =\frac{11400}{40}\\ \rm X_{2} =285\\[/tex]
None of X1 and X2 is greater than 300.
Hence, over 300 students did not support start time after 8:00 am.

Work out m and c for the line: y = 7 − x
The line y = 7 − x has a slope(m) of - 1 and y-intercept b is 7.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, an equation of a line y = 7 - x.
We can rearrange this in the form of slope-intercept form which is
y = mx + b.
y = - x + 7.
y = (-1)x + 7.
The slope (m) of this line is - 1 and the y-intercept(b) is 7.

Answer:

Step-by-step explanation:
Mean of x = Σx / n
Mean of x = (14 + 19 + 13 + 6 + 9) / 5 = 12.2
Sum of square (SS) :
(14-12.2)^2 + (19-12.2)^2 + (13-12.2)^2 + (6-12.2)^2 + (9-12.2)^2 = 98.8
Mean of y = Σy / n
Mean of y = (101 + 89 + 48 + 21 + 47) / 5 = 61.2
Σ(y - ybar)² = (101-61.2)^2 + (89-61.2)^2 + (48-61.2)^2 + (21-61.2)^2 + (47-61.2)^2 = 4348.8
df = n - 2 = 5 - 2 = 3
Σ(y - ybar)² / df = 4348.8 / 3 = 1449.6
√(Σ(y - ybar)² / df) = √1449.6 = 38.074
Standard Error = √(Σ(y - ybar)² / df) / √SS
Standard Error = 38.074 / √98.8
Standard Error = 3.83

The mirror has a frame. The diameter of the mirror with the frame is 17 inches. To the nearest hundredth, what is the area of the mirror with the frame? Use 3.14 for π.
Answer:
the diameter: 17inches
so the radius is: 8.5 inches
the formula for calculating a circle's area:
r×r×π
so:
8.5×8.5×3.14= 226.865
The required to the nearest hundredth, the area of the mirror with the frame is approximately 254.34 square inches.
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
We know that the diameter of the mirror with the frame is 17 inches, which means that the radius of the mirror is half of that or 8.5 inches.
To find the area of the mirror with the frame, we need to subtract the area of the frame from the area of the circle. The area of the circle is:
[tex]A_{circle} = \pi r^2A_{circle} = 3.14 \times (8.5)^2A_{circle} \approx 226.98\ \ \ square inches[/tex]
To find the area of the frame, we need to subtract the area of the inner circle (the mirror) from the area of the outer circle (the frame). The radius of the inner circle is 8.5 inches, and the radius of the outer circle is half of the diameter of the mirror, or 8.5 + (1/2) = 9 inches.
The area of the frame is:
[tex]A_{{frame}} = \pi (9^2) - \pi (8.5^2)A_{frame} = 3.14 \times (81 - 72.25)A_{frame} \approx27.36 \ \ \ square inches[/tex]
Now we can find the area of the mirror with the frame by adding the area of the circle and the area of the frame:
[tex]A_{mirror\ with \ frame} = A_{circle} + A_{frame}A_{mirror\ with \ frame} \approx 226.98 + 27.36A_{mirror\ with \ frame} \aprrox 254.34 \ \ \ square inches[/tex]
Therefore, to the nearest hundredth, the area of the mirror with the frame is approximately 254.34 square inches.

To find:
The measures of FG, EG and angle F.
Solution:
In triangle EFG,
[tex]m\angle E+m\angle F+m\angle G=180^\circ[/tex] [Angle sum property]
[tex]60^\circ+m\angle F+90^\circ=180^\circ[/tex]

[tex]m\angle F=180^\circ-150^\circ[/tex]
[tex]m\angle F=30^\circ[/tex]
In a right angle triangle,
[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]\sin E=\dfrac{FG}{EF}[/tex]
[tex]\sin (60^\circ)=\dfrac{FG}{10\sqrt{2}}[/tex]
[tex]\dfrac{\sqrt{3}}{2}\times 10\sqrt{2}=FG[/tex]
[tex]5\sqrt{6}=FG[/tex]
Similarly,
[tex]\sin F=\dfrac{EG}{EF}[/tex]
[tex]\sin (30^\circ)=\dfrac{EG}{10\sqrt{2}}[/tex]
[tex]\dfrac{1}{2}\times 10\sqrt{2}=EG[/tex]
