4) The mass of a chest is 498 kg when it is 1/2 filled with treasure.
The mass of the same chest is 712 kg when it is 3/4 filled with treasure.
What is the mass of the empty chest?
Answer:
926kg
Step-by-step explanation:
712kg-498kg=214kg+712kg=926kg
3/4. 2/4. 1/4. 3/4. 4/4
Answer:
70kg
Step-by-step explanation:
Firstly, because nothing else changed about the treasure chest apart from the amount of treasure when the mass increased, the difference in mass must be the mass of the 1/4 chest of treasure which was added.
712 - 498 = 214kg
Now that we know that 1/4 chest's worth of treasure has a mass of 214kg, we can multiply this by 2 to find the mass of 1/2 a chest of treasure (without the chest):
214 x 2 = 428 kg
We now know that since 1/2 a chest of treasure has a mass of 428kg, the difference between the mass of the chest AND treasure when it is half full must be the mass of the box:
498 (mass of chest and 1/2 chest worth of treasure) - 428 (mass of just 1/2 chest worth of treasure only) = 70kg (mass of chest only)
We can check this by using the other given mass as well. 214 x 3 = 642kg
This means 3/4 of a chest's worth of treasure only, has a mass of 642kg, meaning the extra mass in the 712kg must be the mass of the chest:
712 - 642 = 70kg
The chest has a mass of 70kg.
Hope this helped!
A recent estimate by a large distributor of gasoline claims that 60% of all cars stopping at their service stations chose unleaded gas and that super unleaded and regular were each selected 20% of the time. In order to check the validity of these proportions, a study was conducted of cars stopping at the distributor's service stations in a large city. The results were as follows:
Gasoline Selected
Regular Unleaded Super Unleaded
51 261 88
Carry out a significance test of the distributors claim
Answer:
We reject the null hypothesis and conclude that at least 2 proportions differ from the stated value.
Step-by-step explanation:
There are 3 types of gas listed in the question.
Thus;
n = 3
DF = n - 1
DF = 3 - 1
DF = 2
Let's state the hypotheses;
Null hypothesis; H0: P_regular = P_super unleaded = 20%; P_i leaded = 60%
Alternative hypothesis; Ha: At least 2 proportions differ from the stated value.
Observed values are;
Regular gas; O = 51
Unleaded gas; O = 261
Super Unleaded; O = 88
Total observed values = 51 + 261 + 88 = 400
We are told that super unleaded and regular were each selected 20% of the time and that unleaded gas was chosen 60% of the time.
Thus, expected values are;
Regular gas; E = 20% × 400 = 80
Unleaded gas; E = 60% × 400 = 240
Super Unleaded; E = 20% × 400 = 80
Formula for chi Square goodness of fit is;
X² = Σ[(O - E)²/E]
X² = (51 - 80)²/80) + (261 - 240)²/240) + (88 - 80)²/80)
X² = 13.15
From the chi Square distribution table attached and using; DF = 2 and X² = 13.15, we can trace the p-value to be approximately 0.001
Also from online p-value from chi Square calculator attached, we have p to be approximately 0.001 which is similar to what we got from the table.
Now, if we take the significance level to be 0.05, it means the p-value is less than it and thus we reject the null hypothesis and conclude that at least 2 proportions differ from the stated value.

A basketball player has a 0.654 probability of making a free throw. If the player shoots 13 free throws, what is the probability that she makes less than 6 of them?
Insert the correct symbol to represent this probability.
Provide your answer below:
P(X
5)
Using the binomial distribution, it is found that there is a 0.0432 = 4.32% probability that she makes less than 6 of them.
-----------------------
For each throw, there are only two possible outcomes. Either she makes it, or she misses it. The probability of making a throw is independent of any other throw, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
x is the number of successes. n is the number of trials.p is the probability of a success on a single trial.The probability of making less than 6 is:
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{13,0}.(0.654)^{0}.(0.346)^{13} \approx 0[/tex]
[tex]P(X = 1) = C_{13,1}.(0.654)^{1}.(0.346)^{12} \approx 0[/tex]
[tex]P(X = 2) = C_{13,2}.(0.654)^{2}.(0.346)^{11} = 0.0003[/tex]
[tex]P(X = 3) = C_{13,3}.(0.654)^{3}.(0.346)^{10} = 0.0020[/tex]
[tex]P(X = 4) = C_{13,4}.(0.654)^{4}.(0.346)^{9} = 0.0093[/tex]
[tex]P(X = 5) = C_{13,5}.(0.654)^{5}.(0.346)^{8} = 0.0316[/tex]
Then
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0 + 0 + 0.0003 + 0.0020 + 0.0093 + 0.0316 = 0.0432[/tex]
0.0432 = 4.32% probability that she makes less than 6 of them.

The brgy. Ginebra kings have won 3 title in the last 11 years. At this rate, how long it will take to win 20 pba titles?
Answer:
It will take 74 years for the Gimebra Kings to win 20 titles.
Step-by-step explanation:
Given that the Ginebra Kings have won 3 titles in the last 11 years, to determine, at this rate, how long it will take to win 20 titles, the following calculation must be performed:
(11/3) x 20 = X
3.666 x 20 = X
73,333 = X
Thus, it will take 74 years for the Ginebra Kings to win 20 titles.
In a class of students, the following data table summarizes how many students play
an instrument or a sport. What is the probability that a student chosen randomly
from the class plays a sport or an instrument?
Answer:
19/28
Step-by-step explanation:
People who count: 4 + 2 + 13 = 19
Total amount of pplz: 19 + 9 = 28
Answer:
15/28
Step-by-step explanation:
The total amount of students in the class is 28. This will be useful for later.
From this table, we can see that 2 people play sports alone and 13 play an instrument alone. Since it says the number of students that play a sport or an instrument, this means that the top left box is not counted. This leaves you with an answer of 15/28.
The radius of a sphere is increasing at a rate of 5 mm/s. How fast is the volume increasing (in mm3/s) when the diameter is 60 mm
Answer:
The volume of the sphere is increasing at a rate of 56,549 cubic millimeters per second.
Step-by-step explanation:
Volume of a sphere:
The volume of a sphere is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In which r is the radius.
Solving this question:
The first step do solve this question is derivating V implictly in function of t. So
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
The radius of a sphere is increasing at a rate of 5 mm/s.
This means that [tex]\frac{dr}{dt} = 5[/tex]
Diameter is 60 mm
This means that [tex]r = \frac{60}{2} = 30[/tex]
How fast is the volume increasing (in mm3/s) when the diameter is 60 mm?
This is [tex]\frac{dV}{dt}[/tex]. So
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
[tex]\frac{dV}{dt} = 4\pi*30^2*5 = 900*20\pi = 56549[/tex]
The volume of the sphere is increasing at a rate of 56,549 cubic millimeters per second.

it takes electricians 36 days to wire a new housing subdivision. how many days would 32 electricians take to do the same job?
Answer:
The 32 electricians will take 1 day and 3 hours to complete the wiring.
Step-by-step explanation:
Since it takes electricians 36 days to wire a new housing subdivision, to determine how many days would 32 electricians take to do the same job the following calculation must be performed:
36/32 = X
1.125 = X
1 = 24
0.125 = X
0.125 x 24 = X
3 = X
Therefore, the 32 electricians will take 1 day and 3 hours to complete the wiring.

Solve 2Q + 5s=r for s and show ALL your steps.
Answer:
2q-r= 5s
divide both sides by 5
2q-r/s =5s/5
therefore S= 2q-r/s
Answer:
Step-by-step explanation:
Subtract 2Q from both sides
2Q + 5s − 2Q = r − 2Q
Simplify
5s = r − 2Q
Divide both sides by 5

Ms. Mason is picking a movie theater to take her family to when they come to visit.
Cinemark is offering a package of 8 tickets for $82.00
Alamo Drafthouse is selling 5 tickets for $47.50
Which movie theater is the better deal? How do you know?
Answer:
Alamo Drafthouse
Step-by-step explanation:
Divide 82 by 8 to get the cost per ticket of Cinemark.
82 / 8 = 10.25
Divide 47.5 by 5 to get the cost per ticket of Alamo Drafthouse.
47.5 / 5 = 9.5
Alamo Drafthouse has the better deal.
