Answer:
Maya has 3 dollars and Fiona has 13
Step-by-step explanation
The linear equations are x + y = 16 and y = 3x + 4. Then the amount of the money of Maya and Fiona is $3 and $13.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Maya and Fiona have a total of $16.
Fiona has $4 more than triple the amount Maya has.
Let the amount of money Maya has to be x and the amount of money Fiona has to be y.
Then the equations will be
x + y = 16
y = 3x + 4
Then on solving the equations, we have
x = 3 and y = 13
The amount of money each of the girls has plotted on the graph.

If z = -1.3, mu=80, sigma=30 What is the actual data value? Round to 2 decimal places.
Step-by-step explanation: This simple confidence interval calculator uses a Z statistic and sample mean (M) to generate an interval estimate of a population mean (μ).
Note: You should only use this calculator if (a) your sample size is 30 or greater; and/or (b) you know the population standard deviation (σ), and use this instead of your sample's standard deviation (an unusual situation). If your data does not meet these requirements, consider using the t statistic to generate a confidence interval.
where:
M = sample mean
Z = Z statistic determined by confidence level
sM = standard error = √(s2/n)
As you can see, to perform this calculation you need to know your sample mean, the number of items in your sample, and your sample's standard deviation (or population's standard deviation if your sample size is smaller than 30). (If you need to calculate mean and standard deviation from a set of raw scores, you can do so using our descriptive statistics tools.)

Value of x = 15.1 unit (Approx.)
Step-by-step explanation:
Given:
For angle 54°
Base of triangle = 11 unit
Perpendicular of triangle = x unit
Find:
Value of x
Computation:
Using trigonometry function;
Tanθ = Perpendicular / Base
Tan 54 = Perpendicular of triangle / Base of triangle
Tan 54 = x / 11
1.376 = x / 11
Value of x = 1.376 × 11
Value of x = 15.136
Value of x = 15.1 unit (Approx.)

Answer:
∠4, ∠3, and ∠5
In the shown figure, angles ∠3, ∠4, and ∠5 are exterior angles.
What is the exterior angle?The exterior angle is outside of the polygon. It is additional to the polygon's inner angle at the same vertex. The sum of an exterior angle and its internal angle is always 180 degrees.
To identify the exterior angles in a figure, determine the angles that are on the outside side of two parallel lines but on two sides of the transversal.
In the illustration, if a transversal connects two parallel lines, the angles generated outside the parallel lines are referred to as external angles.
As per the question,
In the shown figure, angles ∠3, ∠4, and ∠5 are exterior angles.
Hence, the correct answers are options A, C, and E.

let
(hypotenuse ) c = 10 in
(perpendicular) a = 8 in
(base) b =?
By using Pythagoras theorem
c^2= a^2+b^2
(10)^2 = (8)^2 +(b)^2
100 = 64 +(b)^2
100- 64 = (b)^2
36 = (b)^2
√36 = b
6 = b
hence b= 6 in

In the figure below, AB is a diameter of circle P What is the arc measure of minor arc
Answer:
The measure of minor arc AD in degrees is = 42 degrees.
Step-by-step explanation:
The line AB is the diameter of the circle. This also implies that the line dive=ides the circle into two equal halves.
The angle subtended by the diameter of a circle is 180degrees.
This means that angle APD + DPG + CPB = 180 degrees
Already, we can infer that angle DPC = 90 degrees because of the rectangular symbol drawn around point P
Hence we can have
(7x + 1) + 90 +(9x - 7) = 180
16x = 96
the value of x is = 96/16 = 6
we can now plug the value of x into tha expression for the value of angle APD = (7(6) +1) = 42 degrees
Hence APD = 42 degrees.
The measure of minor arc AD in degrees is = 42 degrees.

Question #6
Show steps
Correct answer is A
We'll first need to determine what the composite function f(g(x)) is equal to.
Start with the outer function f(x). Then replace every copy of x with g(x). Afterward, plug in g(x) = 3x-2
So we get the following:
[tex]f(x) = \sqrt{x^2-4}\\\\f(g(x)) = \sqrt{(g(x))^2-4}\\\\f(g(x)) = \sqrt{(3x-2)^2-4}\\\\f(g(x)) = \sqrt{9x^2-12x+4-4}\\\\f(g(x)) = \sqrt{9x^2-12x}\\\\[/tex]
Next, we apply the derivative
[tex]f(g(x)) = \sqrt{9x^2-12x}\\\\f(g(x)) = (9x^2-12x)^{1/2}\\\\f'(g(x)) = \frac{1}{2}(9x^2-12x)^{-1/2}*\frac{d}{dx}(9x^2-12x)\\\\f'(g(x)) = \frac{1}{2}(9x^2-12x)^{-1/2}*(18x-12)\\\\f'(g(x)) = \frac{9x-6}{\sqrt{9x^2-12x}}\\\\[/tex]
Don't forget about the chain rule. The chain rule is applied in step 3 of that block of steps shown above.
The last thing we do is plug in x = 3 and simplify.
[tex]f'(g(x)) = \frac{9x-6}{\sqrt{9x^2-12x}}\\\\f'(g(3)) = \frac{9*3-6}{\sqrt{9*3^2-12*3}}\\\\f'(g(3)) = \frac{21}{\sqrt{45}}\\\\f'(g(3)) = \frac{21}{\sqrt{9*5}}\\\\f'(g(3)) = \frac{21}{\sqrt{9}*\sqrt{5}}\\\\f'(g(3)) = \frac{21}{3*\sqrt{5}}\\\\f'(g(3)) = \frac{7}{\sqrt{5}}\\\\[/tex]
Side note: if you choose to rationalize the denominator, then you'll multiply both top and bottom by sqrt(5) to end up with [tex]f'(g(3)) = \frac{7\sqrt{5}}{5}\\\\[/tex]; however, your teacher has chosen not to rationalize the denominator.
