Toni rents bowling shoes for $6. She bowls 2 games and spends a total of $22. Write and solve an algebraic equation to find the cost of each game.
Answer:
22=2x+6
Step-by-step explanation:
you subtract 6 from both sides
that leaves u with 16=2x
then divide 2 by 16 and that equals
8
so 8=x
each game costs $8
you put the 2 in front of the x in the beginning due to Toni playing 2 games while the shoes are a one time fee.
A health worker is interested in determining if omega-3 fish oil can help reduce cholesterol in adults. She obtains permission to examine the health records of 200 people in a large medical clinic and classifies them according to whether or not they take omega-3 fish oil. She also obtains their latest cholesterol readings and finds that the mean cholesterol reading for those who are taking omega-3 fish oil is 18 points lower than the mean for the group not taking omega-3 fish oil. This is an example of

This is an example of a;
T-test
Step-by-step explanation:
A t-test is a statistic test from which inferences can be drawn based on weather the difference in the means of two sample groups that could have particular common characteristics. The t-test is used for data sets that are normally distributed and the variance may be unknown
The t-test is used to test a proposed hypothesis (assumption) about a population
Therefore, based on the interest of the health worker to determine if omega-3 fish oil can help reduce cholesterol in adults by finding the difference in the means for the group taking omega-3 fish oil and the group not taking omega-3 fish oil, from which it can be determined if the difference in mean is statistically significant, is an example of a t-test

Answer:
b=5 a=6
Step-by-step explanation:
x^5/6=x^b/a
5/6=b/a
b=5, a=6.
Answer:
a = 6
b = 5
Step-by-step explanation:
[tex] \large \boxed{ {a}^{ \frac{m}{n} } = \sqrt[n]{ {a}^{m} } }[/tex]
Plug those values in.
[tex] \large{ {x}^{ \frac{5}{6} } = \sqrt[6]{ {x}^{5} } }[/tex]
From the question, our a is 6 and b is 5.

Una familia buscá una vivienda valorizado en 200000 mil soles. Para lo cual buscan su financiamiento atravesó de 3 bancos, las cuales proponen las condiciones que se muestran en la tabla
Answer:
Banco A o banco B
Step-by-step explanation:
Question:
La tabla obtenida de una pregunta similar en el sitio se presenta a continuación;
[tex]\left |\begin{array}{ccccc}Entidad \ bancaria&Cuota \ inicial&Tasa \ de \ interes \ anual &\mid &Tiempo \ anos \\Banco \ "A"&10\%&15\%&\mid&20\\Banco \ "B"&20\%&13\%&\mid &25\\Banco \ "C"&0\%&10\%&\mid&30\end{array}\right |[/tex]
¿Qué banco es el más conveniente para financiar la vivienda familiar?
Para el banco A, tenemos;
El pago inicial = 10/100 × 200,000 = 20,000
El interés = 180.000 × 15 × 20/100 = 540.000
Importe total, A = 540.000 + 20.000 = 560.000
Para el banco B, tenemos;
El pago inicial = 20/100 × 200,000 = 40,000
El interés = 160.000 × 13 × 25/100 = 520.000
Importe total, B = 520.000 + 40.000 = 560.000
Para el banco C, tenemos;
El pago inicial = 0/100 × 200,000 = 0
El interés = 200.000 × 10 × 30/100 = 600.000
Monto total, C = 600,000 + 00 = 600,000
Por lo tanto, la familia debe seleccionar el banco A o el banco B que tenga el monto total de reembolso más bajo

Find M
Answer:
Step-by-step explanation:
Let angle ABZ be angle 1 and angle ZBC be angle 2.
Angle 1 = 85 degree
Angle 2 = 6x + 9
measure of angle ABC = 24x+4
Angle 2 = ABC - 85
6x + 9 = 24x + 4 - 85
6x - 24x = 4 - 85 - 9
-18x = -90
x = -90/-18 = 90/18 =
x = 5
Therefore the measure of angle 2 = 6*5 + 9 = 30+9 = 39 degree
Therefore the measure of angle ZBC = 39 degree

Enter the patriot equivalent to Tan (A)
And
Enter the ratio equivalent to cos (B)
Answer:
[tex](a)\ \tan A = \frac{5}{12}[/tex]
[tex](b)\ \cos B = \frac{5}{13}[/tex]
Step-by-step explanation:
Given
See attachment for triangles
Solving (a)
[tex]\tan(A)[/tex]
The tan of an angle is:
[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
From the given triangle.
[tex]Opposite = 5[/tex]
[tex]Adjacent = 12[/tex]
So, we have:
[tex]\tan A = \frac{5}{12}[/tex]
Solving (b)
[tex]\cos(B)[/tex]
The cos of an angle is:
[tex]\cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]
From the given triangle.
[tex]Adjacent = 5[/tex]
[tex]Hypotenuse = 13[/tex]
So, we have:
[tex]\cos B = \frac{5}{13}[/tex]
Please HELP I will make you brainlist !!! Need surface area
Answer:
22969.39 yd^2
Step-by-step explanation:
Alright to start, lets do the easier part of it, the sides of it. Since it is an octagonal prism, there are 8 rectangular sides to it. Each of these sides can be found with L*W, so use the given length of 15 and width of 6 to do this.
15 * 6 = 90
Since there's 8 of these:
90 * 8 = 720
Now, with the tricky part with the bases of the octagonal prism. Let's find the perimeter of the octagon, so use the top width of each of the rectangles.
6 * 8 = 48 = Perimeter
Now, here's the magic equation to avoid making this more complicated:
2(1+√2)p^2
Then plug in p
2(1+√2)48^2
(2+2√2) * 2304
(2+2.8284)*2304
4.8284*2304
11124.69...
But there's two bases so: 22249.39
Lastly, add this to the 720 from the rectangular prisms.
22249.39+720 = 22969.39
Hope that helps.
