The probability that a four is obtained on at least one of the rolls 51.71 %.
We need to use this formula in order to find out the probability of getting 4
1 – 54/64
=1 - 625/1296
= 671/1296
= 51.71%
Hence , the probability that a four is obtained is 51.71 %.
A traditional die is a cube with each of its six faces marked with a different number of dots from 1 to 6. Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that proportion is true. The probability of an event is a number between 0 and 1 , where roughly speaking , 0 indicated impossibility of the event and 1 indicates certainty.

Point Q is the midpoint of segment PR. QR = 18 and PR = 5x+6.
we get the value of x as 2.4 units when QR is 18 units.
We are given a segment PR.
We are also given that Q is the mid point of the segment.
So, we get that
PQ = QR
Now, we have that
QR = 18 units
PR = 5 x + 6
We have to sind the value of x.
Substituting the values of PR and QR in the equation, we get that:
5 x + 6 = 18
5 x = 18 - 6
5 x = 12
x = 12 / 5
x = 2.4 units
Therefore, we get the value of x as 2.4 units when QR is 18 units.

Using a system of equations, it is found that you should mix 7 pounds of dried fruit and 3 pounds of nut.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable x: Number of pounds of dried fruit mix.Variable y: Number of pounds of nut mix.The mixture has a total of 10 pounds, hence:
x + y = 10 -> y = 10 - x -> x = 10 - y.
Considering the cost per pound of each, and the total cost of 10 x 5.34 = $53.4, we have that:
4.5x + 7.3y = 53.4.
Replacing x = 10 - y, we have that:
4.5(10 - y) + 7.3y = 53.4.
2.8y = 8.4.
y = 8.4/2.8
y = 3.
x = 10 - 3 = 7.
You should mix 7 pounds of dried fruit and 3 pounds of nut.

A cannonball is fired in the air at an angle of 45∘. How far does it travel before it is
1,700 feet above ground? (Assume the cannonball travels in a straight line. Ignore the force of gravity and wind resistance. Give your answer to the nearest foot.)
It travels 2404 feet before it is 1,700 feet above ground;
The given question can be represented in the form of equation;
y = tan(45°)x + c;
Since it is launched from ground; c = 0;
thus; y = x is the equation of motion of cannonball;
According to question; y = 1700 feet
x = 1700 feet;
The distance travelled by cannonball will be
√(x² + y² = √(1700² + 1700²) (∵ it is a right angled triangle;
using Pythagoras theorem)
= 2404.16 feet
≅ 2404 feet

as far as I can tell after reading this multiple times, this is again looking for the GCF : the greatest common factor.
so, again, prime factor analysis :
168 :
168 ÷ 2 = 84
84 ÷ 2 = 42
42 ÷ 2 = 21
21 ÷ 2 no
21 ÷ 3 = 7
7 ÷ 3 no
7 ÷ 5 no
7 ÷ 7 = 1 finished
168 = 2³×3×7
120 :
120 ÷ 2 = 60
60 ÷ 2 = 30
30 ÷ 2 = 15
15 ÷ 2 no
15 ÷ 3 = 5
5 ÷ 3 no
5 ÷ 5 = 1 finished
120 = 2³×3×5
the GCF is the part of the prime factors both numbers share :
2³×3 = 8×3 = 24
so, they can make 24 fruit cups with identical content and using all the fruits.
these pieces of information were missing in the text.
based on the text without the answer options I was already going for the maximum that each fruit cup has one piece of fruit, and that gives us 168 + 120 = 288 fruit cups max.

Mr. Lee is retiling his pantry floor. His pantry measures 4½ feet by 6½ feet. Each tile he plans to use measures ½ foot by ½ foot.
Answer:
117 tiles
Step-by-step explanation:
Area of rectangle = length * width
To find the number of tiles divide the area of pantry floor by the area of a tile.
Convert mixed fraction to improper fraction.
[tex]\sf 4\dfrac{1}{2}=\dfrac{9}{2}\\\\\\6\dfrac{1}{2}=\dfrac{13}{2}[/tex]
[tex]\sf \boxed{\text{\bf Number of tiles = $\dfrac{Area \ of \ floor}{area \ of \ a \ tile}$}}[/tex]

Use KCF method.
Keep the first fraction.Change division to multiplication.Flip the second fraction.[tex]\sf =\dfrac{117}{4}*\dfrac{4}{1}\\\\= 117[/tex]

What is the value of x in the equation 1/5x - 2/3y =30, when y = 15
Answer:
x = 200
Step-by-step explanation:
1/5x - 2/3y = 30 when y = 15

1/5x - 10 = 30
1/5x = 40
x = 200
Answer:
x = 200
Step-by-step explanation:

A school club consists of 26 male students and 11 female students. If 4 students are selected to represent the club in the student government, what is the probability 2 will be male and 2 will be female?
The probability of selecting two male students is 0.47
The probability of selecting two female students is 0.08
Given,
Number of male students in a school club = 26
Number of female students in a school club = 11
Total number of students in the club = 26 + 11 = 37
Number of students selected to represent the club in the student government = 4
We have to find the probability of selecting 2 male and 2 female students:
Then,
The probability of selecting two male students = (26 / 37) × (25 / 37) = 0.47
The probability of selecting two female students = (11 / 37) × (10 / 37) = 0.08

was the maximum number of people that could be helped with one plane of supplies?
Using a system of equations, it is found that the maximum number of people that could be helped with one plane of supplies is: 40,000.
What is a system of equations?A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.
For this problem, the variables are given as follows, considering the situation described:
Variable x: number of food kits sent.Variable y: number of medicine kits sent.Each food kit helped 8 people and each medicine kit helped 6 people, hence the total number of people helped is given by:
T = 8x + 6y.
This is because we consider that people were helped by only one of them, never both.
Each plane could carry no more than 80,000 pounds. Each food kit weighed 20 pounds and each medicine kit weighed 10 pounds, hence:
20x + 10y = 80000
2x + y = 8000
y = 8000 - 2x.
The maximum volume is of 6000 cubic feet, hence:
x + y = 6000.
y = 6000 - x.
Equaling both equations:
8000 - 2x = 6000 - x
x = 2000.
y = 6000 - x = 4000.
Then the maximum number of people helped is:
T = 8x + 6y = 8 x 2000 + 6 x 4000 = 40,000.

Which expression can be used to convert 100 USD to Japanese yen?
Answer:
The expression that would be most useful in converting $100 to Japanese Yen is 100 ( 99.30487 Yen / 1)
You can use direct proportion to solve this:
If $1 is to Y99.30487 then what will $100 be equal to:
1 : 99.30487 Yen
100 : x
Cross multiply to get:
1x = 99.30487 Yen x 100
x = (99.30487 Yen x 100) / 1
Which can be written as:
= 100 ( 99.30487 Yen / 1)
In conclusion, the most useful expression to convert $100 to Yen is 100 (99.30487 Yen / 1)
