The number of views in the four weeks round to the whole number is 48.
Here it is given that the initial number of views for a reader board was 25 and it gets increased at the rate of 18% per week.
We have to find the number of views in the fourth week.
On the first week the increase = 25 + 25× 18%
= 25 + 25 × 18/100
= 25 + 4.5
= 29.5
The second week increase = 29.5 + 29.5 × 18%
= 29.5 + 5.31
= 34.81
The third week increase = 34.81 + 34.81 × 18%
= 34.81 + 6.2658
= 41.0758
The fourth week increase = 41.0758 + 41.0758 × 18%
= 41.0758 + 7.393644
= 48.469444
Therefore the number of views in the four weeks is 48.

Ada lives 12 4/5 miles from her aunt's house. she lives 17 3/8 miles from her grandmother's house. how many more miles does jada live from her grandmother's house than her aunt's house?
Answer:
[tex]4 \frac{23}{40}\; \rm miles[/tex]
Step-by-step explanation:
To find how many more miles Ada lives from her grandmother's house than her aunt's house, we need to subtract the distance to her aunt's house from the distance to her grandmother's house.
Ada lives 17 3/8 miles from her grandmother's house.
Ada lives 12 4/5 miles from her aunt's house.
Convert both mixed numbers into improper fractions by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, and placing the answer over the denominator:
[tex]17 \frac{3}{8}=\dfrac{17 \cdot 8+3}{8}=\dfrac{139}{8}[/tex]
[tex]12 \frac{4}{5}=\dfrac{12 \cdot 5+4}{5}=\dfrac{64}{5}[/tex]
As both improper fractions have a different denominator, we need to change both fractions into equivalent fractions with the same denominator. To do this, find the least common multiple (LCM) of the denominators, 8 and 5.
The LCM of 8 and 5 is 40. Therefore, convert the fractions into their equivalent fractions (with 40 as their denominator) by multiplying the numerator and denominator by the same number:
[tex]\dfrac{139}{8}=\dfrac{139 \cdot 5}{8 \cdot 5}=\dfrac{695}{40}[/tex]
[tex]\dfrac{64}{5}=\dfrac{64 \cdot 8}{5 \cdot 8}=\dfrac{512}{40}[/tex]
Now the fractions have the same denominator, we can carry out the subtraction by simply subtracting the numerators:
[tex]\dfrac{695}{40}-\dfrac{512}{40}=\dfrac{695-512}{40}=\dfrac{183}{40}[/tex]
Finally, convert the improper fraction into a mixed number by dividing the numerator by the denominator:
[tex]183 \div 40=4\;\rm remainder \;23[/tex]
The mixed number answer is the whole number and the remainder divided by the denominator:
[tex]4 \frac{23}{40}[/tex]
Therefore, Ada lives 4 23/40 miles more from her grandmother's house than her aunt's house.
suppose that when a transistor of a certain type is subjected to an accelerated life test, the lifetime x (in weeks) has a gamma distribution with mean 24 weeks and standard deviation 12 weeks. (a) what is the probability that a transistor will last between 12 and 24 weeks? (b) what is the probability that a transistor will last at most 24 weeks? (c) is the median of the lifetime distribution less than 24? why or why not?
The probability that the transistor will last between 12 and 24 weeks is 0.424
the probability that a transistor will last at most 24 weeks is 0.567
The median of the lifetime distribution is less than 24
X= lifetime of the transistor in weeks E(X)= 24 weeks
O,= 12 weeks
The anticipated value, variance, and distribution of the random variable X were all provided to us. Finding the parameters alpha and beta is necessary before we can discover the solutions to the difficulties.
a) X~gamma([tex]\alpha , \beta[/tex])
E(X)= [tex]\alpha \beta[/tex] [tex]\beta[/tex] =[tex]12^{2}/24[/tex] =6 weeks
V(x)=[tex]\alpha \beta ^{2}[/tex] [tex]\alpha[/tex]=24/6= 4
Now we can find the solutions:
The excel formula used to create Figure one is as follows:
=gammadist(X,[tex]\alpha[/tex] ,[tex]\beta[/tex] , False)
P([tex]12\leq X\leq 24[/tex])
P([tex]12/6 \leq X\leq 24/6[/tex])
P([tex]2\leq X\leq 4[/tex])
P= 0.424
Therefore, the probability that the transistor will last between 12 and 24 weeks is 0.424
b) For this case we want this probability:
[tex]P(X\geq 24)=1-P(X\leq 24)[/tex]
In order to find this probability we can use excel with the following code:
=1-GAMMA.DIST(24,4,6,TRUE)
And we got:
[tex]P(X\geq 24)=P(1-X\leq 24)= 0.567[/tex]
c) For this case the median of the lifetime distribution is less than 24
[tex]P(X\leq \alpha )[/tex] = 0.5 (by definition) So [tex]\alpha[/tex]< 24 because P([tex]X\leq 24[/tex])=0.567 which is greater than 0.5

Define estimated intercept.The expected mean value of Y when all X=0 is the intercept, also referred to as the constant. Create a regression equation with X as the only predictor to begin. The expected mean value of Y at that value is the intercept in the event that X occasionally equals 0. When x is 0, the projected value for y—the intercept of the regression line—is simply 0. A line's slope and intercept can be expressed in terms of the equation y = slope x x + intercept. The Value of Interception The point where the function crosses the y-axis is known as the intercept and is frequently denoted as a constant. In some analyses, removing the intercept and reducing the regression line to Y = bX + error causes the regression model to only become significant.

Find the quadratic using the graph.
Step-by-step explanation:
the standard form is
f(x) = y = a(x - h)² + k
(h, k) are the vertex coordinates. here (-2, -9).
a is the stretch factor.
since the parabola opens upwards, a is positive.
so, we see already :
y = a(x + 2)² - 9
to get a we need an additional point on the curve. we see e.g. (1, 0) :
0 = a(1 + 2)² - 9 = a×3² - 9 = 9a - 9
9a = 9
a = 1
so, our standard form is

Graph the image of the given triangle after the transformation that has the rule (x, y) −> (x - 1, y+5) .
Answer:
I do not see the original triangle, but you would take the original and move it one unit to the left and 5 units up.
Step-by-step explanation:
For example, if the three vertices (corners) of the triangle were points:
(0,0), (1,5) and (-2,3).
Point (0,0) would move to (-1, 5) 0-1 and 0+5
Point (1,5) would move to (0, 10)
Point (-2,3) would move to (-3, 8)
Answer:
To graph the image of the triangle after the transformation, we first need to have the coordinates of the vertices of the original triangle. Once we have those coordinates, we can apply the transformation to each vertex to obtain the coordinates of the corresponding vertex in the transformed image. Then, we can plot the three transformed vertices to obtain the image of the triangle.
Let's say the original triangle has vertices A, B, and C with coordinates A(x1, y1), B(x2, y2), and C(x3, y3), respectively.
To obtain the transformed coordinates of A, we apply the transformation rule (x, y) → (x - 1, y + 5) to the coordinates of A:
A' = (x1 - 1, y1 + 5)
Similarly, we can obtain the transformed coordinates of B and C:
B' = (x2 - 1, y2 + 5)
C' = (x3 - 1, y3 + 5)
Now that we have the transformed coordinates of the three vertices, we can plot them to obtain the image of the triangle.
Here's an example:
Suppose the original triangle has vertices A(2, 4), B(5, 6), and C(7, 3). Applying the transformation rule (x, y) → (x - 1, y + 5) to each vertex gives us:
A' = (2 - 1, 4 + 5) = (1, 9)
B' = (5 - 1, 6 + 5) = (4, 11)
C' = (7 - 1, 3 + 5) = (6, 8)
Plotting these three points gives us the image of the triangle after the transformation:
Before transformation:
B (5, 6)

/ \
A (2, 4) C (7, 3)
After transformation:
B' (4, 11)

four vehicles are traversing a 1-km segment of a highway and the following observations are made: vehicle a: 1.2 min vehicle b: 1.5 min vehicle c: 1.7 min vehicle d: 1.4 min what is the space-mean speed?
Using the concept of average speed we conclude that the space-mean speed of the vehicles is 0.69 km/min.
What is space-mean speed?The average speed of a vehicle traveling a given segment of a highway in a specific time period is called space-mean speed, i.e.
Average mean speed = total distance traveled / average time travel
Given for vehicles are traversing a 1 km segment of highway. Hence total distance is 4km.
Average time = (1.2 + 1.5 + 1.7 + 1.4)/4
= 5.8/4

passes through A (2, "-5)" parallel to BC with (1, 3) and ( 4, 5) PLS HURRRY!!!!!
The equation for the linear equation parallel to BC is:
y = (2/3)*x - 19/3
How to get the linear equation?
A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through two points (x1, y1) and (x2, y2), then the slope is:
slope = (y2 - y1)/(x2 - x1)
And two lines are parallel if both lines have the same slope and different y-intercept.
So if we want to et a line parallel to BC whose endpoints are (1, 3) and ( 4, 5), the slope should be:
slope = (5 - 3)/(4 - 1) = 2/3
So our line is like:
y = (2/3)*x + b
And this must pass through (2, -5)
Replacing these values we get:
-5 = (2/3)*2 + b
-5 - 4/3 = b
-15/3 - 4/3 = b
-19/3 =b
Then the linear equation is:
y = (2/3)*x - 19/3
