Lashonda is saving money to buy a game. So far she has saved $6, which is two-thirds of the total cost of the game. How much does the game cost?
Answer:
The game costs $9
Step-by-step explanation:
I wrote an equation using the variable "t" for the total cost of the game.
6=2/3t
t=6/2/3
t=(6/1)(3/2)
t=18/2
t=9
An operations analyst counted the number of arrivals per minute at an ATM in each of 30 randomly chosen minutes. The results were: 0, 3, 3, 2, 1, 0, 1, 0, 0, 1, 1, 1, 2, 1, 0, 1, 0, 1, 2, 1, 1, 2, 1, 0, 1, 2, 0, 1, 0, 1. For the Poisson goodness-of-fit test, what is the expected frequency of the data value X
Step-by-step explanation:
since Poisson distribution parameter is not given so we have to estimate it from the sample data. The average number of of arrivals per minute at an ATM is
[tex]\hat{\lambda}=\bar{x}=\frac{\sum x}{n}=\frac{30}{30}=1[/tex]
So probabaility for [tex]\mathrm{X}=1[/tex] is
[tex]P(X=1)=\frac{e^{-\lambda} \lambda^{x}}{x !}=\frac{e^{-1} \cdot 1^{1}}{1 !}=0.3679[/tex]
So expected frequency for [tex]X=1[/tex] is [tex]0.3679^{*} 30=11.037[/tex] (or [tex]\left.11.04\right)[/tex] .

Which factor is least likely to affect the results and interpretation of a functional MRI?
A. cancerous growth
B. prescription medication
C. a sinus infection
D. caffeinated soda
Answer:
Cancerous growth
Step-by-step explanation:
For example, a tumor would be found in MRIs and will have a significant impact on the results and interpretation of a functional MRI. A tumor that is cancerously growing is very crucial to the function of an MRI

The functional MRI also known as fMRI monitors brain anatomy activity
The factor that is least likely to affect the results and interpretation of a
functional MRI is; C. A sinus infection.
Reasons:
MRI stands for magnetic resonance imaging, and it is used to generate
images of the interior of items, such as the human body, without opening
the body, by producing strong magnetic fields, from the built in powerful
magnets.
The parts of the body that are examined by an MRI scan includes, the
internal organs, blood vessels, brain, and spinal cord.
The MRI scan works by tracking radio signals sent by protons in the body
which vary based on the type of tissue.
Due to the requirement for the patient to remain stationary during the
scan, medication may be given. It is also important to not take caffeinated
drinks prior to the examination.
A functional MRI is used to monitor the functioning of the brain's anatomy,
by blood flow change detection.
Therefore, the factor that is least likely to affect the result and
interpretation of a functional MRI is a sinus infection which is the
inflammation of the sinus lining and mucus presence, that rarely cause
neurologic complications.

The inequality equation is x > 3 and the graph is plotted
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
3(8 - 4x) < 6(x - 5)
24 - 12x < 6x - 30 (Distributive property)
Adding 30 and 12x on both sides , we get
24 + 30 < 6x + 12x
On further simplification , we get
54 < 18x
Divide by 18 on both sides , we get
x > 3
Hence , the inequality is x > 3

Find cos(a) in the triangle.
Answer:
cos(α) = 24/25.
Step-by-step explanation:
First of all, we'll find the answer just using the fact that ABC is a right triangle in C. So, by the definition of cosine:
[tex]\cos(\alpha) = \dfrac{AC}{AB}\\\\\boxed{\cos(\alpha) = \dfrac{24}{25}}[/tex]
Now, we'll solve the question with another approach. By the Law of Cosines in the triangle ABC:
[tex]BC^2 = AB^2+AC^2-2\cdot AB\cdot AC\cos(\alpha)\\\\7^2 = 25^2+24^2-2\cdot 25\cdot 24\cos(\alpha)\\\\49 = 625+576-1200\cos(\alpha)\\\\1200\cos(\alpha)=1152\\\\\boxed{\cos(\alpha) = \dfrac{24}{25}}[/tex]

write an equation for the line passing through the points (3,-6) and (-9,-6) y=mx+b format.
Answer:
y=-6
Step-by-step explanation:
First, find the slope of the two coordinates using the slope formula:
Slope formula: y2-y1/x2-x1
Plug the numbers into the formula and solve:
-6--6/-9-3 = 0
Now,use the slope and one of the coordinates to put the line in point-slope form
Point slope: y-y1=m(x-x1)
y+6=0(x-3)
Simplify
y+6=0-0
y=-6

Simplify this expression: -2.15m + 6 + 10.3m
Answer:
8.15m + 6
Step-by-step explanation:
To simplify, combine like terms. The only like terms here are the -2.15m and 10.3m because they both have a variable next to them.
Add the numbers together and leave the variable the same.
-2.15m+10.3m = 8.15m
Answer:
8.15m + 6
Step-by-step explanation:
-2.15m + 6 + 10.3m
combine like terms: -2.15 + 10.3 = 8.15

Answer:
32 and 5n + 2
Step-by-step explanation:
(a)
The pattern of the number of sticks is
7, 12, 17
There is a common difference of 5 between consecutive terms.
Thus to obtain the number of sticks in number 6 , add 5 to previous terms, that is
a₄ = 17 + 5 = 22
a₅ = 22 + 5 = 27
a₆ = 27 + 5 = 32
There are 32 sticks in pattern number 6
(b)
The sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
Where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 5 , then
[tex]a_{n}[/tex] = 7 + 5(n - 1) = 7 + 5n - 5 = 5n + 2
number of sticks in pattern number n is 5n + 2

1. What is the goal of factoring a quadractic?
2. What is the discriminant?
3. What is meant by completing a square?
Answer:
Completing the square on a quadratic equation in standard form results in the quadratic formula, which expresses the solutions in terms of a, b, and c. Solutions to problems that can be expressed in terms of quadratic equations were known as early as 2000 BC. Because the quadratic equation involves only one unknown, it is called " univariate "
