At the beginning of the week, Josh had 323232 computer games, 133\33, percent as many computer games as Peter had. By the end of the week, Josh gave 25\%%, percent of his computer games to Peter. How many computer games did Josh and Peter each have by the end of the week
Answer:
[tex]Josh =24[/tex]
[tex]Peter = 32[/tex]
Step-by-step explanation:
Given
Beginning of Week
[tex]Josh = 32[/tex]
[tex]Josh = 133\% * Peter[/tex]
First, we calculate the amount Peter has at the beginning of the week
[tex]Josh = 133\% * Peter[/tex]
Make Peter the subject
[tex]Peter = \frac{Josh}{133\%}[/tex]
[tex]Peter = \frac{32}{133\%}[/tex]
[tex]Peter = \frac{32}{1.33}[/tex]
[tex]Peter = 24[/tex]
When Josh gave out 25%.
The number (n) of computers is:
[tex]n = Josh * 25\%[/tex]
[tex]n = 32 * 25\%[/tex]
[tex]n = 8[/tex]
This means that Josh gave out 8 computers.
So, the amount they both have is:
[tex]Josh =32 - 8[/tex]
[tex]Josh =24[/tex]
[tex]Peter = 24+8[/tex]
[tex]Peter = 32[/tex]

A project to build a new bridge seems to be going very well since the project is well ahead of schedule and costs seem to be running very low. A major milestone has been reached where the first two activities have been totally completed and the third activity is 60 percent complete. The planners were expecting to be only 50 percent through the third activity at this time. The first activity involves prepping the site for the bridge. It was expected that this would cost $1,420,000 and it was done for only $1,300,000. The second activity was the pouring of concrete for the bridge. This was expected to cost $10,500,000 but was actually done for $9,000,000. The third and final activity is the actual construction of the bridge superstructure. This was expected to cost a total of $8,500,000. To date they have spent $5,000,000 on the superstructure. Calculate the schedule variance, schedule performance index, and cost performance index for the project to date.
Answer:
Scheduled Variance = $850,000.00
Schedule Performance Index = 1.05
Cost Performance Index = 1.11
Step-by-step explanation:
Note: See the attached excel file for the calculations of Total Actual Cost to Date, Budgeted Cost of Work Scheduled (BCWS), and Budgeted Cost of Work Performed (BCWP).
From the attached excel file, we have:
Total Actual Cost to Date = $15,300,000
Total BCWS = $16,170,000
Total BCWP = $17,020,000
Therefore, we have:
Scheduled Variance = Total BCWP - Total BCWS = $17,020,000 - $16,170,000 = $850,000.00
Schedule Performance Index = Total BCWP / Total BCWS = $17,020,000 / $16,170,000 = 1.05
Cost Variance = Total BCWP - Total actual cost to date = $17,020,000 - $15,300,000 = $1,720,000
Cost Performance Index = Total BCWP / Total actual cost to date = $17,020,000 / $15,300,000 = 1.11

A public health organization reports that 30% of baby boys 6 - 8 months old in the United States weigh more than 20 pounds. A sample of 15 babies is studied. Round the answers to three decimal places. Part 1 of 4 (a) What is the probability that exactly 5 of them weigh more than 20 pounds
Answer:
0.206 = 20.6% probability that exactly 5 of them weigh more than 20 pounds.
Step-by-step explanation:
For each baby, there are only two possible outcomes. Either they weigh more than 20 pounds, or they do not. The probability of a baby weighing more than 20 pounds is independent of any other baby, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
A public health organization reports that 30% of baby boys 6 - 8 months old in the United States weigh more than 20 pounds.
This means that [tex]p = 0.3[/tex]
A sample of 15 babies is studied.
This means that [tex]n = 15[/tex]
What is the probability that exactly 5 of them weigh more than 20 pounds
This is P(X = 5). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 5) = C_{15,5}.(0.3)^{5}.(0.7)^{10} = 0.206[/tex]
0.206 = 20.6% probability that exactly 5 of them weigh more than 20 pounds.
Determine whether the triangles are similar. If so, write a similarity
statement.
Answer:
[tex]\triangle FED\sim \triangle JEH[/tex]
Step-by-step explanation:
Both pairs of vertical angles formed at point E are equal. Therefore, the two triangles share two angles. If two triangles share two angles, they must also share the third angle, since the sum of the interior angles of a triangle add up to 180 degrees. Therefore, all three angles of the two triangles are equal, which is a proof of similarity. [tex]\implies \boxed{\triangle FED\sim \triangle JEH}[/tex]

Alexandra plays poker with seven friends. Each of the eight players starts with 60 chips, but players take chips from one another as play progresses. The goal of the game is to win all of the chips. A player drops out of the game if she loses all her chips to other players in the game. After five players have dropped out of the game, what is the average number of chips each of the remaining players has
Answer:
160 chips
Step-by-step explanation:
Given
[tex]n = 8[/tex] --- players
[tex]c = 60[/tex] --- chips per player
First, calculate the total chips
[tex]Total = n * c[/tex]
[tex]Total = 8 * 60[/tex]
[tex]Total = 480[/tex]
After 5 players are out; there are 3 players remaining in the game
So, the average number of chip with each of the remaining player is:
[tex]Average = \frac{Total}{n-5}[/tex]
[tex]Average = \frac{480}{8-5}[/tex]
[tex]Average = \frac{480}{3}[/tex]
[tex]Average = 160[/tex]

In order to safely land, the angle that a plane approaches the runway should be no more than 15°. A plane is approaching Ottawa Macdonald–Cartier International Airport to land. It is at an altitude of 500 m and a horizontal distance of 3 km from the start of the runway. At what angle is the plane approaching and is it safe for the plane to land?
9514 1404 393
Answer:
9.5°, yes
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
The distance opposite the angle of elevation is the plane's height, 500 m. The distance adjacent to the angle of elevation is the horizontal distance to the plane, 3 km = 3000 m. Then the angle is found from ...
tan(α) = 500/3000 = 1/6
α = arctan(1/6) ≈ 9.46°
The plane is approaching at an angle of 9.46°. It is safe to land, since that angle is less than 15°.

What is a area?
Area is nothing but the surface bounded by the object in 2D.
What is a segment?
A part of a line or curve between two points In circle we can say segment is nothing but a region or area cutoff from the circle by chord.
What is a segment area?
Area bounded by a segment. Area of segment has a formula (θ/360°)πr²
According to the question
θ=120°
radius =10cm
area of segment = (120°/360°)π(10²)
120°/360° =0.333
10²=100
0.333×π×100
33.3π or (100/3)π
Thus area of the shaded segment is 33.3π or (100/3)π square centimeters

I don’t get this one but the question was something about finding the equation.
9514 1404 393
Answer:
y = -(x -3)^2 +2
Step-by-step explanation:
The vertex form of the equation for a parabola is ...
y = a(x -h)^2 +k
where the vertex is (h, k) and the value 'a' is a vertical scale factor.
The value of 'a' can be found by looking at the y-value of points ±1 either side of the vertex relative to the vertex. Here, the vertex y-value is +2 at x=3, and either side goes down 1 unit (to y=1) for 1 unit to the right or left. So, a = -1.
Using the values we've read from the graph for the vertex (h, k) = (3, 2) and the scale factor a = -1, we can write the equation as ...
y = -(x -3)^2 +2
