Step-by-step explanation:
1) [tex]\frac{1}{3}-(\frac{1}{3}*\frac{1}{3}) + (\frac{1}{3}[/tex] ÷[tex]\frac{1}{3}) =[/tex] [tex]\frac{1}{3}-\frac{1}{9} +(\frac{1}{3}*\frac{3}{1})[/tex]
[tex]=\frac{1}{3}-\frac{1}{9}+1\\\\=\frac{1*3}{3*3}-\frac{1}{9}+\frac{1*9}{1*9}\\\\=\frac{3}{9}-\frac{1}{9}+\frac{9}{9}\\\\=\frac{3-1+9}{9}\\\\=\frac{11}{9}\\\\=1\frac{2}{9}\\[/tex]
2)
[tex](3\frac{3}{4}-2\frac{2}{3})*1\frac{1}{2}=(\frac{15}{4}-\frac{8}{3})*\frac{3}{2}\\\\=(\frac{15*3}{4*3}-\frac{8*4}{3*4})*\frac{3}{2}\\\\=(\frac{45}{12}-\frac{24}{12})*\frac{3}{2}\\\\=(\frac{45-24}{12})*\frac{3}{2}\\\\=\frac{21}{12}*\frac{3}{2}\\\\=\frac{21}{4}*\frac{1}{2}\\\\=\frac{21}{8}\\\\=2\frac{5}{8}[/tex]
3) When finding equivalent fractions both numerator and denominator should be multiplied with the same number. But Lethna didn't multiply with the numerator.
[tex]\frac{2}{5}+\frac{1}{2}=\frac{2*2}{5*2}+\frac{1*5}{2*5}\\\\=\frac{4}{10}+\frac{5}{10}\\\\=\frac{9}{10}[/tex]
4) In fraction multiplication convert mixed fraction to improper fraction and reduce to smallest term
[tex]1\frac{1}{2}*5\frac{1}{3}=\frac{3}{2}*\frac{16}{3}\\\\=8[/tex]
5)
[tex]8\frac{2}{3}*5\frac{4}{9}=\frac{26}{3}*\frac{49}{9}\\\\=\frac{1274}{27}\\\\= 47\frac{5}{27}\\\\[/tex]
6) Use Keep Change Flip (KCF) method for fraction division
[tex]4\frac{2}{5}[/tex] ÷ [tex]6\frac{5}{8}[/tex] = [tex]\frac{22}{5}[/tex] ÷ [tex]\frac{53}{8}[/tex]
[tex]= \frac{22}{5}*\frac{8}{53}\\\\=\frac{176}{265}[/tex]

A population of values has a normal distribution with μ=152.8 and σ=26.2 . You intend to draw a random sample of size n=94 . Find the probability that a single randomly selected value is less than 149.6. P(X < 149.6) =
Answer:
P(x < 149.6) = 0.11821
Step-by-step explanation:
We start by calculating the z-score of the parameter given
Mathematically,
z-score = (x-mean)/SD/√n
z-score = (149.6-152.8)/26.2/√94
z-score = -3.2/2.70
z-score = -1.18
So the probability we want to calculate is;
P( x < -1.18)
we can use the standard normal distribution table to get this
From the standard normal distribution table, this value is 0.11821
A student cycles a distance of 63 km in less
than 3 hours. What is the average speed?
Answer:
About About 21 km/h
Step-by-step explanation: If they travel 63 km in 3 hours then all it is is just 63 divided by 3 or 63/3.
The average speed for the cycle will be 21 km per hour.
What is an average speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.
The average speed is defined as the ratio of the total distance traveled and the total time taken by the object.
Given that A student cycles a distance of 63 km in less than 3 hours. The average speed is calculated as:-
Average speed = Distance / time
Average speed = 63 / 3
Average speed = 21 km / hr

What is the equation of the graphed line written in standard form?
Answer:
The last one 5x-3y=15 This is the same as y= (5/3)x -5
Step-by-step explanation:
5x-3y=15
Move 5x to the right (becoming negative)
-3y = -5x +15
Divide everything by - 3
y= (5/3)x -5
y intersect= -5 ( line crosses y coordinate at -5)
Slope = 5/3 From -5 you start counting (5 up,3 right,5 up,3 right.... OR 5 down,3 left,5 down,3 left........)

An independent study commissioned by the stadium showed that running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets. How long should the stadium run the cable ad in order to reach this target?
Answer
I think 55 times
Step-by-step explanation:
13,200/1,200 = 11
5/1200 = x/13,200
so if 1,200*11=13, 200 then 5*11= 55.
btw , could u give me the brainliest if i am right?
The total time the stadium runs the cable ad in order to reach this target is 11 days and this can be determined by using the unitary method.
Given :
Running a cable TV ad 5 times daily for a week generated 1,200 ticket sales. The stadium wants to sell out an upcoming show, which requires the sale of 13,200 tickets.The following steps can be used in order to determine the total times the stadium run the cable ad in order to reach this target:
Step 1 - The unitary method can be used in order to determine the total times the stadium runs the cable ad in order to reach this target.
Step 2 - According to the given data, running a cable TV ad 5 times daily for a week generated 1,200 ticket sales.
Step 3 - If running TV ad 5 times daily sales 1200 tickets then to sell 13200 tickets the total times the ad is running is:
[tex]=\dfrac{13200}{1200}\times 5[/tex]
= 55 times
Step 4 - Now, if 5 times ad running in one day then 55 times ad running in:
[tex]=\dfrac{55}{5}\times 1[/tex]
= 11 days

Identify the property on this equation 5(a + 3b) = 5a + 15b
Answer:
??????????????????????
Step-by-step explanation:
Answer: Distributive Property
The term "distribution" is also used in place of "distributive"
This property says
x*(y+z) = x*y + x*z
We multiply the outer term x with each inner term (y and z). Then we add the results.
In this case,
x = 5
y = a
z = 3b
So,
5(a+3b) = 5*a + 5*3b = 5a+15b

In the last quarter of a high school football game, your team i s behind by 21 points. A field goal is worth 3 points and a touchdown (after the extra point is worth 7 points. Let x represent the number of field goals scored and y represent the number of touchdowns scored. Write an inequality that models the different number of field goals and touchdowns your team could score to win the game. (Assume the other team doesn't score any more points.)
Answer:
3x + 7y > 21
Step-by-step explanation:
3x + 7y > 21
where:
x = number of field goals needed to win
y = number of touchdowns (plus extra point) needed to win
Since your team is 21 points behind and you want to win the game, not tie it, the number of field goals and touchdowns must result in a number higher than 21, not equal to or higher than.
Answer:
3x + 7y > 21

D) 81
Step-by-step explanation:
I think cause you would do 3 by the second power so that would be 9 then 9 the the second power would be 81 so yeah good luck
Answer:
D is your correct answer
Step-by-step explanation:
Well first things first if we want to simplify with a base and an exponent we can use product of two powers with like bases.
-------------------------
Example/model of product of two powers with like bases:
x^m + n (adding the exponents)
-------------------------
If we add those two exponents you get 3^4. Then if you do 3 x 3 x 3 x 3 = ?

A line with a positive slope is parallel to one of the lines shown. What is its slope? Use the graph shown below.
Answer:
2/5
Step-by-step explanation:
first select the line that is positive which is the purple one
slope = change in y / change in x
two clear points are (0,2) and (5,4)
so you do y2-y1 / x2-x1
=(4-2)/(5-0)
=2/5
so the slope is 2/5
How far from the door must a ramp begin in order to rise 3 feet with an 8 degree angle of elevation
Answer:
Step-by-step explanation:
We know that the angle of elevation is 8 degrees.
We know that the height of the opposite side of the angle is 3 feet.
We want to know the adjacent side (the side from the start of the ramp to the bottom of the opposite side)
We can do this with tangent
[tex]tan(8) = \frac{3}{adj} \\adj = \frac{3}{tan(8)} \\adj = 21.34611 feet[/tex]
The distance between the ramp and the door can be calculated using the principle of Pythagoras, Hence, the distance should be 21.34 feets
Angle of elevation = 8°Rise = opposite = 3 feets Distance, d = adjacentUsing SOHCAHTOA :
Tanθ = Opposite / Adjacent
Tan(8°) = 3 / d
0.1405408 = 3 / d
0.1405408d = 3
Divide both sides by 0.1405408 to isolate d
0.1405408d / 0.1405408 = 3 / 0.1405408
d = 21.34 feets
Therefore, the distance of the ramp from the door should be 21.34 feets
