Answer:
(a) not proportional
(b) k = 7/8
Step-by-step explanation:
When a linear equation is of the form ...
y = mx + b
with b ≠ 0, the relation is NOT PROPORTIONAL.
__
If b=0, so the equation is of the form ...
y = kx
then the relation IS PROPORTIONAL. The constant of proportionality is k.
__
(a) Not proportional
(b) Proportional with k = 7/8
An Item is regularly priced at $60. It is now priced at a discount of 65% off the regular price. What is the price now?
Answer:
$21
Step-by-step explanation:
There are two ways to do this question:
1. Multiply 60 by .65 and minus the product from the original price ($60)
2. Multiply 60 by .35 (This is because the discounted price maintains 35% of the regular price)
Let's do it both ways:
1. (60)(.65) = 39
60 - 39 = 21
2. (60)(.35) = 21
Therefore, the price now is $21.
I hope this helps!!
- Kay :)
Answer:
$21.00
Step-by-step explanation:
$60.00*(1.00-.65)
$60.00*(35)

Lindsay is at the movies.
Emily does not like caramel apples.
Janelle is afraid of heights and won't go on rides over 15 feet high.
.
.
Who is the third person riding the Ferris Wheel?
third person =
Answer:
Emily because Lindsay is at the movies so she can't ride the Ferris Wheel. Janelle is too afraid to go that high. Emily only doesn't like caramel apples so she can still go on the Ferris Wheel.
Answer:
Emily
Step-by-step explanation:
The third person riding on the ferris wheel is Emily. why? well Lindsey is at the movies so she can't be at the carnival riding the ferris weel, Janelle is afraid of heights so their is no way she would ride the ferris wheel, but Emily just doesn't like Carmel apples which would not stop her from riding the ferris wheel.

Ford and GM pick up trucks are being tested for fuel efficiency, which is commonly measured in miles per gallon (mpg). The fuel efficiency of Ford trucks is found to follow a normal distribution with mean 20 mpg and a standard deviation of 3 mpg. The fuel efficiency of GM trucks is found to follow a normal distribution with mean 24 mpg and standard deviation of 4 mpg. Compute the probability that a randomly chosen Ford truck outperforms a randomly chosen GM truck in terms of fuel efficiency
Answer:
0.7881 = 78.81% probability that a randomly chosen Ford truck outperforms a randomly chosen GM truck in terms of fuel efficiency
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Subtraction of normal variables:
When we subtract normal variables, the mean is the subtraction of the means, and the standard deviation is the square root of the sum of the variances.
The fuel efficiency of Ford trucks is found to follow a normal distribution with mean 20 mpg and a standard deviation of 3 mpg.
This means that [tex]\mu_{F} = 20, \sigma_{F} = 3[/tex]
The fuel efficiency of GM trucks is found to follow a normal distribution with mean 24 mpg and standard deviation of 4 mpg.
This means that [tex]\mu_{G} = 24, \sigma_{G} = 4[/tex]
Compute the probability that a randomly chosen Ford truck outperforms a randomly chosen GM truck in terms of fuel efficiency
This is the probability that the subtraction of ford by gm is less than 0. First, we find the mean and the standard deviation.
[tex]\mu = \mu_{F} - \mu_{G} = 20 - 24 = -4[/tex]
[tex]\sigma = \sqrt{\sigma_{F}^2+\sigma_{G}^2} = \sqrt{3^2+4^2} = 5[/tex]
This probability is the pvalue of Z when X = 0. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - (-4)}{5}[/tex]
[tex]Z = 0.8[/tex]
[tex]Z = 0.8[/tex] has a pvalue of 0.7881
0.7881 = 78.81% probability that a randomly chosen Ford truck outperforms a randomly chosen GM truck in terms of fuel efficiency

Which statement is true if a is the fourth root of 16, Show your work
a x a x a x a = 16
a = 164
4a = 16
a = 16/4
Given:
The statement is " a is the fourth root of 16".
To find:
The true statement for the given statement.
Solution:
The given statement is
a is the fourth root of 16.
Mathematically, it can be written as
[tex]a=\sqrt[4]{16}[/tex]
Taking power 4 on both sides.
[tex]a^4=(\sqrt[4]{16})^4[/tex]
[tex]a\times a\times a\times a=16[/tex]
Therefore, the correct option is A.
A true statement , if a is the fourth root of 16 is
a x a x a x a = 16
Important Information :
'a' is the fourth root of 16'a' is the fourth root of 16 can be written as
[tex]a=\sqrt[4]{16}[/tex]
To remove fourth root, we take exponent 4 on both sides
[tex]a=\sqrt[4]{16}\\(a)^4=(\sqrt[4]{16})^4[/tex]
Exponent 4 and fourth root will get cancelled
[tex]a^4=16\\a \cdot a\cdot a \cdot a=16[/tex]
a x a x a x a = 16
A true statement , if a is the fourth root of 16 is
a x a x a x a = 16

mean of four numbers a ,b, c, and d is 8 and mean of seven
numbers x , y ,z ,a, b, c and d is 12 . Find the mean of x, y and z.
Answer:
17 1/3 or 17.33Step-by-step explanation:
Mean of four numbers a, b, c, and d is 8:
(a + b + c + d)/4 = 8 ⇒ a + b + c + d = 32Mean of seven numbers x, y, z, a, b, c and d is 12:
(x + y + z + a + b + c + d)/7 = 12Substitute the sum of 4 numbers:
x + y + z + 32 = 7*12x + y + z = 84 - 32x + y + z = 52Mean of x, y and z is:
52/3 = 17 1/3 or 17.33Find a quadratic polynomial verifying f(-3) = – 18, f'(-3) = 16, f''(-3) = - 6.
Let f(x) = ax ² + bx + c. Then
f '(x) = 2ax + b
f ''(x) = 2a
f (-3) = -18, so
9a - 3b + c = -18
f ' (-3) = 16, so
-6a + b = 16
f '' (-3) = -6, so
2a = -6
Then a = -3, b = -2, and c = 3, so that
f(x) = -3x ² - 2x + 3
Mario tiene un comercial tecnológico, vende una cámara web HD con una ganancia del 18% sobre el precio de costo. El compró la cámara en $15,00. ¿Cuál es el precio de venta de la cámara?
Answer:
El precio de venta de la cámara es de $17.70.
Step-by-step explanation:
Dado que Mario vende una cámara web HD con una tasa de ganancia del 18%, y compró dicho elemento a $15.00, para determinar el precio de venta del producto se debe realizar el siguiente cálculo:
15 + (15 x 18 / 100) = X
15 + (15 x 0.18) = X
15 + 2.70 = X
17.70 = X
Por lo tanto, el precio de venta de la cámara es de $17.70.

can someone give me the slope and y-intercept for this problem
Answer:
Slope: 2
Y-intercept: -4
Step-by-step explanation:
Slope = y2 - y1 / x2 - x1
Slope = -2 - -4 / 1 - 0
Slope = 2 / 1
Slope = 2
Y-intercept is when x = 0
This is shown on the first row
When x = 0, y = -4, which is our y-intercept

Step-by-step explanation:
A car's position is given by s(t) = {3 – 5t? + 7t hundreds of meters with t in minutes.
a. Find the time when the car has velocity zero.
b. Find the acceleration of the car when the velocity is zero.
Separate your answers with commas; round all values to 1 decimal(s).
Time(s) at which the velocity is zero:
Acceleration(s) when the velocity is zero:
Answer:
A) (1 s, 2.3 s)
B) (-4 m/s², 3.8 m/s²)
Step-by-step explanation:
The car's position which is the distance is given by the equation;
s(t) = t³ - 5t² + 7t
A) Velocity is the first derivative of the distance. Thus;
v(t) = ds/dt = 3t² - 10t + 7
At v = 0, we have;
3t² - 10t + 7 = 0
Using quadratic formula, we have;
t = 1 and t = 2.3
Thus, time at velocity of 0 is t = (1 s, 2.3 s)
B) acceleration is the derivative of the velocity. Thus;
a(t) = dV/dt = 6t - 10
At velocity of 0, we got t = 1 and t = 2.3
Thus;
a(1) = 6(1) - 10 = -4 m/s²
a(2.3) = 6(2.3) - 10 = 3.8 m/s
Thus, a(t) at v = 0 gives; (-4 m/s², 3.8 m/s²)
