Answer:
175
Step-by-step explanation:
Since the mean is 158
(121+189+147+x)/4=158
121+189+147+x=632
x=175
Answer:
[tex]175[/tex] (thousand dollars) - written in [tex]2/22/2021[/tex]
Step-by-step explanation
In order to know the answer in the question, we should need to solve for the [tex]x[/tex] (Granton). It is other way around in solving for the mean because in here the mean is given. After using this formula, [tex]\frac{121+189+147+x}{4}=158[/tex] we derived at our answer that Granton has a revenue of [tex]175[/tex] (thousand dollars).
To find the value of y using the value of x, use ___ equation of the system.
A. Either
B. Neither
C. The First
D. The Second

There are many variables that affect the calculation of a patient’s total blood volume. For the purposes of this question, weight and age will be the only variables considered. The Australian Red Cross states that “Blood volume can be estimated as approximately 70mL/kg for adults, 80mL/kg in children…”. Work on the assumption that an adult is a person aged 16 years or over and a child is a person aged 2 to 16 years.
Let:
W = Weight (kg)
P = Plasma volume (mL) and
T = Total blood volume (mL)
Write 2 equations for calculating Total blood volume (T) given Weight (W), expressing T in terms of W, one for adults and one for children:
Answer:
The two equations are;
For adults, T = W kg × 70 mL/kg ............Equation (1)
For children, T = W kg × 80 mL/kg.............Equation (2)
Step-by-step explanation:
We are told that
Blood volume = 70 mL/kg for adults
Blood volume = 80 mL/kg in children
Therefore, the total blood volume,T of an adult of weight, W is given by the following relation;
T = W kg × 70 mL/kg ............Equation (1)
The total blood volume,T of a child of weight, W is given by the following relation;
T = W kg × 80 mL/kg.............Equation (2).

As the triangle is a right angle triangle we see complimentary to the other angles and as all angles in a triangle equal 180, we see the other two which compliment this.
Step-by-step explanation:
Answer:
53 degrees
Step-by-step explanation:
A circle with radius 9 has a sector with a central angle of 120°.
What is the area of the sector?
120º is 1/3 of a complete revolution of 360º. So the area of this sector should be 1/3 the area of the complete circle.
A circle with radius 9 has area 9^2 π = 81π.
So the sector has area 81π/3.
Put another way: The area A of a circular sector and its central angle θ (in degrees) occur in the same ratio as the area of the entire circle with radius r according to
A / θ º = (π r ^2) / 360º
==> A = π/360 θ r ^2
In this case, r = 9 and θ = 120º, so
A = π/360 * 120 * 81 = 81π/3
4(x+2)=2(3x+5)
I need the answer
Your answer would be x = -1.
We can find this by first expanding the brackets on both sides of the equation:
4x + 8 = 6x + 10
Now we can rearrange and solve for x:
4x + 8 = 6x + 10
- 4x
8 = 2x + 10
- 10
-2 = 2x
÷ 2
-1 = x
I hope this helps!
Answer:
x = - 1
Step-by-step explanation:
Given
4(x + 2) = 2(3x + 5) ← distribute parenthesis on both sides
4x + 8 = 6x + 10 ( subtract 6x from both sides )
- 2x + 8 = 10 ( subtract 8 from both sides )
- 2x = 2 ( divide both sides by - 2 )
x = - 1

Tarzan is swimming east at 2.4 m/s across a river that is 1660 meters wide and
flows north at 5.2 m/s
What is tarzan’s final rate of swimming?
Tarzan’s final rate of swimming is 4.83 minutes.
What is velocity?Velocity is the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference.
Now it is given that,
Tarzan is swimming east at Velocity, Vt = 2.4 m/s
River's Velocity flowing north, Vr = 5.2 m/s
Width of river = 1660 meters
So, resultant speed of Tarzan, V = √(Vt² + Vr²)
⇒ V = √(2.4² + 5.2²)
⇒ V = √(5.76 + 27.04²)
⇒ V = √32.8 m/s
⇒ V = 5.73 m/s
Thus, rate of swimming = Width / V
⇒ rate of swimming = 1660 / 5.73 s
⇒ rate of swimming = 289.70 s
or, rate of swimming = 4.83 minutes
Thus, Tarzan’s final rate of swimming is 4.83 minutes.

When Nick checked his work it did not match the standard form function. Analyze Nick’s work. What was his mistake?
In step 1, he did not put the function in standard form correctly.
In step 2, he should have also factored –7 from the constant term, 17.
In step 3, he did not subtract –7(9) to keep the function equivalent.
In step 4, he did not write the perfect square trinomial correctly as a binomial squared.
In step 3, he did not subtract –7(9) to keep the function equivalent. Therefore, the correct option is option C among all the given options.
What is mathematical function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a predictor variables (the dependent variable).
In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences. German mathematician Paul Dirichlet initially offered the standard concept of function in 1837. When Nick checked his work it did not match the standard form function. In step 3, he did not subtract –7(9) to keep the function equivalent.
Therefore, the correct option is option C.

Your question is incomplete but most probably your full question was,
Nick wrote the function p(x) = 17 + 42x – 7x2 in vertex form. His work is below.
p(x) = –7x2 + 42x + 17
p(x) = –7(x2 – 6x) + 17
= 9;
p(x) = –7(x2 – 6x + 9) + 17
p(x) = –7(x – 3)2 + 17
When Nick checked his work it did not match the standard form function. Analyze Nick’s work. What was his mistake?
In step 1, he did not put the function in standard form correctly.
In step 2, he should have also factored –7 from the constant term, 17.
In step 3, he did not subtract –7(9) to keep the function equivalent.
In step 4, he did not write the perfect square trinomial correctly as a binomial squared.
Nick made mistakes in converting to standard form, factoring constants correctly, maintaining equivalence, and writing perfect square trinomials. Correcting these steps will yield an accurate transformation of the equation.
Let's break down the steps Nick likely took and identify where he went wrong in putting the quadratic equation into its standard form.
Step 1: Initially converting the equation to standard form. For the equation x² + 4x + 21 = 0, the equation was already in standard form, so no changes were necessary here. It’s possible that Nick incorrectly adjusted coefficients, which led to errors.Step 2: Factoring out terms. If Nick had an equation like -7x² + 17 = 0, he should have factored out -7 from both the x² term and the constant term, resulting in -7(x² - 17/7) = 0. Missing this step would lead to misrepresentation of the equation.Step 3: Ensuring equivalence. Nick should have subtracted -7(9) correctly to maintain the function's equivalence throughout the transformation.Step 4: Writing the perfect square trinomial correctly. To complete the square, for example, (x + 2)² should be correctly represented as a binomial squared. Not doing so indicates an error in the transformation process.In summary, Nick’s mistakes include incorrect standard form conversion, improper factoring of constant terms, failing to maintain equivalence, and incorrect representation of perfect square trinomials.
