Step-by-step explanation:
H0 : μ = 840
H1 : μ < 840
Sample size, n = 49
Standard deviation, s = 14
Test statistic = (xbar - μ) ÷ (s/√(n))
Test statistic = (830 - 840) ÷ (14/7)
Test statistic = - 10 / 2
Test statistic = - 5

Bridgette has drawn a representation of a sphere with a
radius of 3 units, using the graphs of a circle and an ellipse,
as shown in the picture below on the left.
She needs to determine the equations of the graphs that
will generate the representation of the 3D sphere, as
shown in the picture below on the right.
What are possible equations of the circle and ellipse that
Bridgette can use to create her 3D drawing?
Answer:
C
Step-by-step explanation:
You want the equations of the circle and ellipse in the given figure.
EquationsThe standard form equation for an ellipse is ...
[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1[/tex]
where 'a' and 'b' are the semi-axes in the x-direction and y-direction, respectively.
You will notice that when a=b=r, the ellipse becomes a circle and the equation can be rewritten as ...
[tex]\dfrac{x^2}{r^2}+\dfrac{y^2}{r^2}=1\ \Longleftrightarrow\ x^2+y^2=r^2[/tex]
ApplicationHere, the radius is 3, the same as the semi-major axis in the x-direction (a=3). The ellipse axis in the y-direction appears to be about 1/3 that value, so b=1, and the equations of the circle and ellipse are ...
[tex]x^2+y^2=9\qquad\text{circle}\\\\\dfrac{x^2}{9}+\dfrac{y^2}{1}=1\qquad\text{ellipse}[/tex]

What is graphs?Graphs are visual representations or charts used in mathematics to methodically express data or values. A relationship between two or more objects is frequently represented by a point on a graph. A non-linear data structure called a graph is made up of nodes, or vertices, and edges. Connect the nodes, also known as vertices. This graph comprises a set of vertices V= 1, 2, 3, 5, and a set of edges E= 1, 2, 1, 3, 2, 4, and (2.5), (3.5), (4.5).

Tell whether the angles are complementary or supplementary. Then find the value of x.
The angles add up to 180° so the angles are supplementary.
The value of x is 31.
What are corresponding angles?The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.
Corresponding angles are equal.
We have,
From the figure,
Two angles:
3x + 25 and 2x
These two angles form a straight angle.
Now,
3x + 25 + 2x = 180
5x = 180 - 25
5x = 155
x = 31
When the sum of two angles is 90°, then the angles are known as complementary angles.
When the sum of two angles is 180°, then the angles are known as supplementary angles.
Now,
3x + 25
= 3 x 31 + 25
= 93 + 25
= 118
2x
=2 x 31
= 62
Now,
118 + 62 = 180
Thus,
The angles are supplementary.
The value of x is 31.

{y|y > -0.1}
while this includes all positive numbers, it also includes all numbers between -0.1 and 0. e.g. -0.001
so, NO
{x|x in N}
N is the set of all natural numbers. that is the set of all positive integers.
so, YES
{y : 0 < y < 1}
that is all numbers between 0 and 1. that's are only positive numbers between 0 and 1.
so, YES
{x|x in Z}
Z is the set of all integer numbers (including the negative ones). so, NO
{y : 3 <= y < 22}

Therefore , the solution of the given problem of linear equation comes out to be (2,2).
A linear equation is defined.A linear equation is one that has the form y=mx+b in algebra. B is the slope, and m is the y-intercept. It's usual to refer to the previous clause as a "linear equation with two variables" because y and x are variables. The two-variable linear equations known as bivariate linear equations. There are several instances of linear equations: 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. It is referred to as being linear when an equation has the form y=mx+b, where m stands for the slope and b for the y-intercept.
Here,
=> y+ x = 3
=> y= 3-x
=> x= y = 1
=>3-x =1
=> x = 2
=> y = 2
(2,2)
Therefore , the solution of the given problem of linear equation comes out to be (2,2).

If a house has decreased 35% since it was purchased and it currently values 117,000 what was purchase value
Step-by-step explanation:
that means the current value of $117,000 is 100 - 35 = 65% of the original price.
65% = $117,000
1% = 65%/65 = 117000/65 = $1,800
100% = 1%×100 = 1800×100 = $180,000
the original (100%) purchase value was $180,000.

Part A
g(x) = 9.25x
g(8) = 9.25*8
g(8) = 74
He would make $74 before taxes if he worked 8 hours.
------------------------------------------------------
Part B
g(x) = 9.25x
g(14) = 9.25*14
g(14) = 129.50
He would make $129.50 before taxes if he worked 14 hours.
------------------------------------------------------
Part C
g(x) = 9.25x
g(27.5) = 9.25*27.5
g(27.5) = 254.375
g(27.5) = 254.38
He would make $254.38 before taxes if he worked 27.5 hours.
Answer:
Solution below.
Step-by-step explanation:
SolutionThis question is basically asking you to substitute corresponding x values to find g(x).
Given the function from the question:
g(x) = 9.25x where x is the work hours and g(x) is the wages.
Given x = 8,
g(8) = 9.25 * 8 = $74.00
Given x = 14,
g(14) = 9.25 * 14 = $129.50
Given x = 27.5,
g(27.5) = 9.25 * 27.5 = $254.38 (rounded off to nearest cent)
