What are the values of a and b?
a=
b=
Answers
Answer:
The values of a and b are:
a = 2[tex]b=4[/tex]Step-by-step explanation:
Given the exponential model
[tex]y=a\cdot \:b^x[/tex]
Given the points
(0, 2) and (3, 128)
We know that the y-intercept of [tex]y=a\cdot \:b^x[/tex] is (0, a).
so
a = 2
putting x = 3, y = 128 and a = 2
[tex]y=a\cdot \:b^x[/tex]
[tex]128=2\cdot \:b^3[/tex]
Switching sides
[tex]2b^3=128[/tex]
[tex]\frac{2b^3}{2}=\frac{128}{2}[/tex]
[tex]b^3=64[/tex]
Taking the real value such as:
[tex]\mathrm{For\:}x^3=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt[3]{f\left(a\right)}[/tex]
so
[tex]b=\sqrt[3]{64}[/tex]
[tex]b=\sqrt[3]{4^3}[/tex]
[tex]b=4[/tex]
Therefore,

Kaylee is a high school basketball player. In a particular game, she made some two point shots and some three point shots. Kaylee scored a total of 24 points and made 3 more three point shots than two point shots. Graphically solve a system of equations in order to determine the number of two point shots made, x,x, and the number of three point shots made, yy. How would you graph this?
Answers
Answer:
Kaylee made [tex]6[/tex] two point shots and [tex]3[/tex] three point shots.
Explanation:
You know that a two point shot would be worth [tex]2[/tex] points. You also know that a three point shot would be worth [tex]3[/tex] points, and that she scored a total of [tex]24[/tex] points. Using this information you can create the first equation:
[tex]3x+2y=24[/tex]
For the second equation, you know that Kaylee scored [tex]3[/tex] more three point shots than two point shots.
[tex]y+3=x[/tex]
You would then graph it as a system of equations. Using the graph, you can figure out the solution of the system of equations, [tex](6,3)[/tex]. For the two equations above, we made two point shots [tex]x[/tex], and we made three point shots [tex]y[/tex], so Kaylee made [tex]6[/tex] two point shots and [tex]3[/tex] three point shots.

The following are prices of selected digital cameras. $158, $95 ,$175, $180 ,$95,$129, $228, $300 Find the standard deviation.
Answers
Answer: 69.23
Step-by-step explanation:
Given data:
N = 8.
μ = 170.
Solution:
First we calculate for the mean.
= 158 + 95 + 175 + 180 + 95 + 129 + 228 + 300/8
= 1360/8
= 170.
Next we calculate for (xi - μ)
(158 - 170) = (-20)^2 = 400
(95 - 170) = (-75)^2 = 5625.
(175 -170 ) = (5)^2 = 25.
(180 -170) = (10)^2 = 100
(95 - 170) = (-75)^2 = 5625.
(129-170) = (-41)^2 = 1681
(228 -170) = (58)^2 = 3364.
(300-170) = (130)^2 = 16900.
Summation of (xi - μ)
= 400 + 5625 +25 + 100 + 5625 + 1681 + 3364 + 16900
= 33720.
S = Σ√(xi - μ) /n-1
= √( 33720 - 170 ) / 8-1
= √ (33550/7)
= √4792.86
= 69.23
Standard deviation is 69.3

Flo and Carl each must read a 500-page book. Flo reads one page every minute. Carl reads one page every 50 seconds. Flo starts reading at 1:00, and Carl starts reading at 1:30. When will Carl catch up to Flo?
Answers
Answer:
Carl will catch up Flo at 4:00Step-by-step explanation:
Given
Flo reads one page every minuteCarl reads one page every 50 secondsCarl starts 30 minutes lateMax number of pages = 500Let x be the number of pages each reads when Carl catches up Flo
Then we have the time for Flo and Carl
Flo:
x pages after x minutesCarl:
x pages after 30 + x*50/60 minutesThe time is same:
x = 30 + 50/60xx = 30 + 5/6xx - 5/6x = 301/6x = 30x = 6*30x = 180180 minutes = 3 hours
1:00 + 3 hours = 4:00
✭Flo and carl must read a 500 page book.
✭Flo reads one page every 1 minute (60seconds).
✭Carl reads one page every 50 Seconds.
✭Flo starts reading at 1:00.
✭Carl starts reading at 1:30.
[tex]\large\bold{\underline{\underline{To \: Find:-}}}[/tex]When will carl catch up to flo?
[tex]\large\bold{\underline{\underline{Solution:-}}}[/tex]Let Flo read certain pages when carl catches up with him. Then carl also read the same amount pages at that time.
Let the time passed be "x" minutes.
If carl Reads 1 page every 50 seconds, then 50 seconds can be written as 5/6th of a minute.
Carl's rate will be:
[tex]Carl \: \: Rate \: = \frac{Page}{Minutes} = \frac{ \frac{1}{5} }{6} = \frac{6}{5} [/tex]Now, flo got a 30 minute head start. therefore, when carl catches up, he will read certain pages at x + 30 minutes.
And the number of pages that carl read after the time he had started, that is, "x" minutes will be:
[tex] ⇒\frac{6}{5} \times x[/tex]But, the number of pages carl and flo read will be the same at that time!
[tex] ⇒\frac{6x}{5} = x + 30[/tex][tex] ⇒\frac{6x}{5} - x = 30[/tex][tex] ⇒\frac{x}{5} = 30[/tex][tex]⇒x = (30 \times 5) \: \: minutes[/tex][tex]⇒x = (150) \: \: minutes[/tex]So carl catches up after 150 minutes.
Now, 1:30 + 150 minutes = 1.5 hours + 2.5 hours = 4:00.

It is given that:
The school that Mike goes to is selling tickets to a play.
Let x be the price each of senior citizen ticket and y is the price of one student ticket
The equation can be framed as:
11x + 2y = 41
13x + 3y = 51
After solving the linear equation by substitution method:
x = 3
y = 4
Thus, the price of each of one senior citizen ticket and one student ticket is $3 and $4 respectively.

Step-by-step explanation:
We have the two functions:
[tex]g(t)=t^2-t\text{ and } f(x)=1+x[/tex]
And we wish to find:
[tex]g(f(2)+3)[/tex]
First, let’s find f(2) first. So, we will substitute 2 for x for f(x):
[tex]f(2)=1+(2)=3[/tex]
Hence, we can now substitute 3 for f(2):
[tex]g(f(2)+3)=g(3+3)=g(6)[/tex]
Now, we can find g(6). Substitute 6 for t for g(t):
[tex]g(6)=(6)^2-(6)=36-6=30[/tex]

A couple wishes to replace the carpeting in their master bedroom. Their master bedroom measures 24 ft by 16 ft. If carpeting is sold by the square yard, how many square yards of carpeting are needed
Answers
Answer:
128 yards^2
Step-by-step explanation:
So basically you just need to find the area of the room and then con vert it into yards.
24 ft x 16 ft = 384 ft^2
1 yard = 3 feet
384/3 = 128
128 yards^2
Hope this helps and have a good day!
42.7 yard² square yards of carpeting are needed to replace the carpeting in their master bedroom
3 feet = 1 yard
The length of bedroom = 24 ft. = 24 ft. * 1/3 yard per feet
Length of bedroom = 8 yards
Width of bedroom = 16 ft. = 16 ft. * 1/3 yard per feet
Width of bedroom = 16/3 yards
The area of the masters bedroom is:
Area = length * width
Area = 8 yards * 16/3 yards
Area = 42.7 yard²
Hence 42.7 yard² square yards of carpeting are needed to replace the carpeting in their master bedroom

primeros cuatro exámenes de Stephen sus calificaciones son 92, 87, 96 y 77,
¿cuál es la minima calificación que Stephen puede recibir en el quinto examen
para obtener una A en el curso?
Answers
Answer:
La mínima calificación que Stephen puede recibir en el quinto examen para obtener una A en el curso es 98.
Step-by-step explanation:
La media (también llamada promedio o media aritmética) de un conjunto de datos es una medida de posición central. Es el valor obtenido al sumar todos los datos y dividir el resultado entre el número total de datos.
En este caso, el número total de datos es 5 y el valor de los datos de los cuales debes obtener el problema es 92, 87, 96, 77 y un valor desconocido de un quinto examen. Y sabes que este valor debe ser igual o mayor a 90.
Esto se expresa matemáticamente como:
[tex]\frac{92+87+96+77+nota}{5}[/tex]≥90
donde "nota" es la mínima calificación que Stephen puede recibir en el quinto examen para obtener una A en el curso.
Resolviendo:
[tex]\frac{352+nota}{5}[/tex]≥90
352+nota≥90*5
