Answers
Answer:
x = 6, y = -8
Step-by-step explanation:
First we take the equations side by side and put them like this:
6x + 2y = 16
+ 2x - 2y = 32
8x = 48
Then solve for x.
x = 6
Then insert x back into either equation
2(5) - 2y = 32
10 - 2y = 32
solve for y,
y = -10
there are 750 spectator in the stadium of which 420 are women and the rest are men
Answers
Complete Question:
There are 750 spectator in the stadium of which 420 are women and the rest are men. What percent of the spectators are women?
Answer:
Percentage = 56%
Step-by-step explanation:
Given the following data;
Total number of people = 750
Number of women = 420
To find the percentage of women;
First of all, we would determine the number of male spectators (men);
Number of men = Total number of people - Number of women
Number of men = 750 - 420
Number of men = 330
Next, we find the percentage of women;
[tex] Percentage = \frac {420}{750} * 100 [/tex]
[tex] Percentage = \frac {42}{75} * 100 [/tex]
[tex] Percentage = 0.56 * 100 [/tex]
Percentage = 56%
Therefore, the percentage of the spectators that are women is 56%.

Answers
Answer:
452.4 in³
Step-by-step explanation:
Volume half sphere = 1/2 volume sphere
Volume sphere = 4/3πr²
Volume = 4/3*3.14*27 Radius = 1/2(6) . 3³ = 27
Volume ≈ 113.1
Volume Cylinder = Area circle x hieght
Area circle = πr²
Area circle = 3.14 * 9
Area circle = 28.26
Volume cylinder = 28.26 * 12 = 339.12
339.12 + 113.1 = 452.22
Because of rounding it would be ≈ 452.4

find the measure of one interior angle in a regular 23-gon
Answers
Answer: A polygon with 23 sides has a total of 3780 degrees. total interior angles = (n - 2)180°, where n is the number of sides.
The measure of one interior angle of the given regular polygon with 23 sides is 164.3 degrees
How to calculate the sum of the interior angle of a regular polygon?The formula which is used to calculate the sum of the angle of regular polygon is given by
sum of the interior angles = ( n - 2 ) × 180 degrees
Where,
n is the number of sides
According to the given question.
We have a regular polygon with 23 sides.
⇒ n = 23
Therefore,
The sum of the interior angles of the given regular polygon
= (23-2) × 180
= 3,780 degrees
So, the measure of one interior angle = [tex]\frac{3780}{23} = 164.3 degrees[/tex]
Hence, the measure of one interior angle of the given regular polygon with 23 sides is 164.3 degrees.

a) When x = −2 and y = 1, is Q(x, y).
a. true

c) Give values different from those in part (c) for which Q(x, y) has the same truth values as in part.
Answers
Answer:
a) Q(-2,1) is false
b) Q(-5,2) is false
c)Q(3,8) is true
d)Q(9,10) is true
Step-by-step explanation:
Given data is [tex]Q(x,y)[/tex] is predicate that [tex]x<y[/tex] then [tex]x^{2} <y^{2}[/tex]. where [tex]x,y[/tex] are rational numbers.
a)
when [tex]x=-2, y=1[/tex]
Here [tex]-2<1[/tex] that is [tex]x<y[/tex] satisfied. Then
[tex](-2)^{2}<1^{2}[/tex]
[tex]4<1[/tex] this is wrong. since [tex]4>1[/tex]
That is [tex]x^{2}[/tex][tex]>y^{2}[/tex] Thus [tex]Q(x,y)[/tex] [tex]=Q(-2,1)[/tex]is false.
b)
Assume [tex]Q(x,y)=Q(-5,2)[/tex].
That is [tex]x=-5, y=2[/tex]
Here [tex]-5<2[/tex] that is [tex]x<y[/tex] this condition is satisfied.
Then
[tex](-5)^{2}<2^{2}[/tex]
[tex]25<4[/tex] this is not true. since [tex]25>4[/tex].
This is similar to the truth value of part (a).
Since in both [tex]x<y[/tex] satisfied and [tex]x^{2} >y^{2}[/tex] for both the points.
c)
if [tex]Q(x,y)=Q(3,8)[/tex] that is [tex]x=3[/tex] and [tex]y=8[/tex]
Here [tex]3<8[/tex] this satisfies the condition [tex]x<y[/tex].
Then [tex]3^{2} <8^{2}[/tex]
[tex]9<64[/tex] This also satisfies the condition [tex]x^{2} <y^{2}[/tex].
Hence [tex]Q(3,8)[/tex] exists and it is true.
d)
Assume [tex]Q(x,y)=Q(9,10)[/tex]
Here [tex]9<10[/tex] satisfies the condition [tex]x<y[/tex]
Then [tex]9^{2}<10^{2}[/tex]
[tex]81<100[/tex] satisfies the condition [tex]x^{2} <y^{2}[/tex].
Thus, [tex]Q(9,10)[/tex] point exists and it is true. This satisfies the same values as in part (c)

וחתן
Answers
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

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
Answers
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.

Mary has three baking pans. Each pan is 8" × 8" × 3". Which expression will give her the total volume of the pans?
Answers
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.

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
