Answer:
The equation of the parallel line will be y = -2.5x - 8.
Step-by-step explanation:
First things first, let's rearrange the line equation provided into a more standard form:
[tex]5x + 2y = 14[/tex]
[tex]5x - 14 = -2y[/tex]
[tex]\frac{5x - 14}{-2} = y[/tex]
[tex]y = -2.5x + 7[/tex]
Therefore, we can see that this line has a slope (the coefficient preceding x) of -2.5. The parallel line must therefore also have a slope of -2.5.
Now, let us set the y-intercept of the parallel line to be (0, a) (since it must be on the y-axis).
If we factor in all of this, we get the equation:
[tex]\frac{a-(-3)}{0-(-2)} = -2.5[/tex]
Remember, the slope is found by dividing the vertical difference with the horizontal difference.
[tex]a - (-3) = -2.5(0+2)[/tex]
[tex]a + 3 = -5[/tex]
[tex]a = -8[/tex]
Hence, the equation of the parallel line will be y = -2.5x - 8.

Suppose a 90% confidence interval for the mean salary of college graduates in a town in Mississippi is given by [$38,737, $50,463]. The population standard deviation used for the analysis is known to be $14,300.
a. What is the point estimate of the mean salary for all college graduates in this town?
Point estimate
b. Determine the sample size used for the analysis.
Sample size
Answer:
a. The point estimate was of $44,600.
b. The sample size was of 16.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
The margin of error is the difference between the two bounds, divided by 2.
a. What is the point estimate of the mean salary for all college graduates in this town?
Mean of the bounds, so:
(38737+50463)/2 = 44600.
The point estimate was of $44,600.
b. Determine the sample size used for the analysis.
First we need to find the margin of error, so:
[tex]M = \frac{50463-38737}{2} = 5863[/tex]
Relating the margin of error with the sample size:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.9}{2} = 0.05[/tex]
Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.64.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
For this problem, we have that [tex]\sigma = 14300, M = 5863[/tex]. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]5863 = 1.645\frac{14300}{\sqrt{n}}[/tex]
[tex]5863\sqrt{n} = 1.645*14300[/tex]
[tex]\sqrt{n} = \frac{1.645*14300}{5863}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.645*14300}{5863})^2[/tex]
[tex]n = 16[/tex]
The sample size was of 16.

3. A bicycle has wheels with a diameter of 622 mm. The
bicycle rolls forward and the wheel turns 5 radians.
How many millimeters forward did the bicycle move?
Distance = ( ) (622) = (15.708) ()
= (2.618)
וחתן
Answer:
1553.6mm
Step-by-step explanation:
Given data
Diameter = 622mm
Radius= 622/2= 311mm
Circumference= 2πr
Circumference= 2*3.142*311
Circumference= 1954.32
Each revolution the wheels will turn 1954.32mm
Now let us convert radian to turns
1 radian= 0.159155 turns
5 radians= x turns
cross multiply
x= 5*0.159155
x=0.795 turns
If 1 turn will give 1954.32mm
0.795 turn will give x
cross multiply
x= 0.795*1954.32
x=1553.6mm
Find the value of angle x to the nearest degree:
COS X = 0.5505
Answer:

x = Cos⁻¹(0.5505)
x = 56.59
Rounding to the nearest degree;
x = 57°

Find the center and radius of x^2 + y^2 +6x - 7=0

The center (-3, 0)

Answer:
center: (-3, 0)radius: 4Step-by-step explanation:
The desired parameters can be found by putting the equation into the standard form for the equation of a circle:
(x -h)^2 +(y -k)^2 = r^2 . . . . . circle centered at (h, k) with radius r
The values of h and k will be half the coefficients of the linear x- and y-terms, respectively.
x^2 +6x +9 +y^2 -7 = 9 . . . . . add 9 to complete the square
(x +3)^2 +y^2 = 16 . . . . . . . . . add 7 to get the desired form
This equation shows us (h, k) = (-3, 0) and r = 4.
The center is (-3, 0), and the radius is 4.
A basketball player scored 14 times during one game. She scored a total of 15 points, two for each two-point shot and one for each free throw. How many two-point shots did she make? How many free throws?
She made ____ two-point shots
Answer:
The player made one two-point shot and 13 free throws.
Step-by-step explanation:
We can write a system of equations to model the situation.
Let t represent the number of two-point shots and let f represent the number of free throws made.
Since she scored a total of 14 times, the sum of two-pointers and free throws must equal 14. Hence:
[tex]t+f=14[/tex]
And since she scored a total of 15 points and each two-pointers is worth two points and every free throw is worth one:
[tex]2t+f=15[/tex]
Solve the system. We can use elimination. From the first equation, multiply both sides by negative one:
[tex]-t-f=-14[/tex]
We can add this to the second equation:
[tex](2t+f)+(-t-f)=(15)+(-14)[/tex]
Simplify:
[tex]t=1[/tex]
So, the player made only one two-point shot.
Using the first equation again, substitute one for t and solve for f:
[tex](1)+f=14\Rightarrow f=13[/tex]
Therefore, the player made one two-point shot and 13 free throws.

Mary has three baking pans. Each pan is 8" × 8" × 3". Which expression will give her the total volume of the pans?
Answer: An expression [tex]3 \times (8 \times 8 \times 3)[/tex] will give her the total volume of the pans.
Step-by-step explanation:
Given: Length = 8 inch
Width = 8 inch
Height = 8 inch
Formula to calculate the volume of rectangular pans is as follows.
[tex]Volume = length \times width \times height\\[/tex]
Substitute the values into above formula as follows.
[tex]Volume = length \times width \times height\\= 8 \times 8 \times 3 in^{3}\\= 192 in^{3}[/tex]
Therefore, volume of each pan is 192 cubic inch. As there are three baking pans so total volume of the pans is as follows.
[tex]3 \times 192 in^{3}\\= 576 in^{3}[/tex]
Thus, we can conclude that an expression [tex]3 \times (8 \times 8 \times 3)[/tex] will give her the total volume of the pans.
This circle is centered at the origin, and the length of its radius is 8. What is the circle's equation? 5 A. X+ y = 8 B. x2 + y2 = 64 O c. x2 + y2 = 8 D. X8+ y = 64
Answer:
Step-by-step explanation:
A circle centered in [tex]P(x_o,y_o)[/tex] an radius [tex]r[/tex] has a equation:
[tex](x-x_o)^2+(y-y_o)^2=r^2[/tex]
So, your equation wold be:
[tex](x-0)^2+(y-0)^2=8^2\Rightarrow x^2+y^2=64[/tex]
The correct circle's equation with radius 8 is,
⇒ x² + y² = 64
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
This circle is centered at the origin, and the length of its radius is 8.
Since, The general equation of circle with center (h, k) and radius r is,
⇒ (x - h)² + (y - k)² = r²
Here, Center = (0, 0)
Radius = 8
Hence, The correct circle's equation with radius 8 is,
⇒ (x - h)² + (y - k)² = r²
⇒ (x - 0)² + (y - 0)² = 8²
⇒ x² + y² = 64
Thus, The correct circle's equation with radius 8 is,
⇒ x² + y² = 64
