Anser: there would be 5 groups with six penanuts each and a remainder group with only 4 peanuts
Step-by-step explanation:
since 34/5 gives a remainder
calculate 30/5 which gives you 6
then you would be left with 4 since 30 +4 is 34
Solve the simultaneous equations.
xy = 4
x + y = 5
Answer:
1,4
4,1
Step-by-step explanation:
y = 4/x
substitute
x + 4/x = 5
multiply the whole thing by x to make life easier
x^2 +4 = 5x
X^2 -5x +4 = 0
(x-1)(x-4)=0
x-1=0 x =1
x-4 =0. x=4
so there are 2 solutions
x=1. y = 4
x =4. y =1
A bag contains three dice, two of which are somewhat unusual: die A is a regular die whose faces show 1,2,3,4,5 and 6. Die B has a 4 on all 6 sides, and the faces of die C are2,2,4,4,6and 6. Suppose that a die is randomly selected, rolled, and comes up a 4. If the same die is rerolled, what is the probability that it is again a 4?

Answer:
41/54
Step-by-step explanation:
I will provide the approach and work it out. However, I am error prone, so check the arithmetic.
This is a Bayes Theorem problem.
Consider 3 "causes for a 4", Die A, B, or C, and an event, E.
The probability of each cause, given the event 4 is
[tex]P(A|4)=\frac{P(A)P(4|A)}{P(A)P(4|A)+P(B)P(4|B)+P(C)P(4|C)}[/tex]
[tex]P(B|4)=\frac{P(B)P(4|B)}{P(A)P(4|A)+P(B)P(4|B)+P(C)P(4|C)}[/tex]
[tex]P(C|4)=\frac{P(C)P(4|C)}{P(A)P(4|A)+P(B)P(4|B)+P(C)P(4|C)}[/tex]
Since the rolled die is chosen at random,
P(A)=P(B)=P(C)=1/3
Also, from the numbers on the faces of each die,
P(4|A)=1/6
P(4|B)=1
P(4|C)=1/3
Making all the substitutions, we get
P(A|4)=1/9
P(B|4)=6/9
P(C|4)=2/9
That these sum to 1 is promising (maybe I didn't make a mistake).
Next we must roll the die again and the probability of a 4 could be because the die is A, B, or C. Thus, the desired probability is given by
P(A|4)P(4|A)+p(B|4)P(4|B)+P(C|4)P(4|C)
This evaluates to
(1/9)(1/6)+(6/9)(1)+(2/9)(1/3)=41/54
rectangle has dimensions 12 litre into 6 CM if you draw a square on the same perimeter what will be its area
Answer:
[tex]Area = 81cm^2[/tex]
Step-by-step explanation:
Given
[tex]Length = 12[/tex]
[tex]Width = 6cm[/tex]
Required
Determine the area of a square with the same perimeter
First, calculate the perimeter (P) of the rectangle.
[tex]P=2*(Length + Width)[/tex]
[tex]P=2*(12 + 6)[/tex]
[tex]P=2*18[/tex]
[tex]P=36[/tex]
The perimeter of a square is:
[tex]P = 4L[/tex]
Where L is the side length.
Substitute 36 for P
[tex]36 = 4L[/tex]
Make L the subject
[tex]L =\frac{36}{4}[/tex]
[tex]L =9[/tex]
The area of the square is:
[tex]Area = L^2[/tex]
[tex]Area = 9^2[/tex]
[tex]Area = 81cm^2[/tex]

for the following exercises, identify the type of data that would be used to describe a response (quantitative discrete, quantitative continuous, or qualitative), and give an example of the data.
14. distance to the closest movie theater
16. number of competing computer spreadsheet software packages
Answer:
14: quantitative continuous
16: quantitative discrete
Step-by-step explanation:
Distance can be any non-negative real number, hence it is continuous.
The number of packages has to be a positive integer, hence is discrete.

x = 2 is not a solution of 7x+5=21.
In a math class with 26 students, a test was given the same day that an assignment
was due. There were 17 students who passed the test and 18 students who completed
the assignment. There were 15 students who passed the test and also completed the
assignment. What is the probability that a student who failed the test completed the
homework?
Answer:
The propability would be 4/26 students who failed the test but completed the
homework
Step-by-step explanation:
The Probability that a student who failed the test completed the homework is [tex]\frac{3}{26}[/tex]
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur,
Given,
Total number of students = 26 students
Number of students who completed the assignment = 18 students
Number of students who pass the test and also completed the assignment = 15 students
Number of students who completed the assignment and fail the test = 18 -15 = 3 students
Then,
Probability = Number of favorable outcome / Total number of outcome
Probability that a student who failed the test completed the homework = [tex]\frac{3}{26}[/tex]
Hence, The Probability that a student who failed the test completed the homework is [tex]\frac{3}{26}[/tex]

Take four pizzas and split them into thirds, what is the answer?
Please give the right answer and show work if possible
Answer:
14
Step-by-step explanation:
Sin(∅) = Opposite angle ÷ hypotenuse.
Sin (45) = 7[tex]\sqrt{2}[/tex] ÷ hypotenuse
hypotenuse = 7[tex]\sqrt{2}[/tex] ÷ sin(45)
*********************
Keep in mind
sin(45) = √2÷2

so we have: Hypotenuse = 7√2 ÷ (√2÷2)
Hypotenuse= 14.

Answer:
the answer is 59 (I got it on khan academy)
Step-by-step explanation:
59 degrees is the measures of the minor arc YZ if diameter of a circle is XZ
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given that diameter of a circle is XZ
We have to find the measure of arc YZ.
11w+5w+4=180
Add the like terms
16w+4=180
Subtract 4 from both sides
16w=176
Divide both sides by 16
w=176/16
w=11
Now plug in w value of yz
yz=5w+4
=5(11)+4
=55+4
=59 degrees
Hence, 59 degrees is the measures of the minor arc YZ.

model this sine function into a cosine function.
sine function: 67.5sin12(x-7.5)+67.5
Answer:
67.5sin12(x - 7.5) + 67.5

8x – y = 42
-43 - 6 = y
Answer:
x = .875 y = -49
Step-by-step explanation:
(8x - y = 42)
(y = -43 - 6) or (y = -49)
Since we have our y value, we can plug it into our top equation:
8x -(-49) = 42
8x + 49 = 42
-42 -42
8x = 7
/8 /8
x = 0.875
To check the work:
8(0.875) - 49 = 42
7 - 49 = 42

Answer:
A) $287.60.
B) $323.55.
C) David would pay more for the laptop at the store.
Step-by-step explanation:
A) Given that the store's website is offering the laptop at a 60% discount off the regular price of $ 719, ignoring tax and shipping, the sale price is obtained through the following calculation:
100 - 60 = 40
719 x 0.40 = X
287.6 = X
Therefore, in this case the sale price would be $ 287.6.
B) Since the store is having a sale, offering a 50% discount off the regular price of the laptop, and David also has an in-store-only coupon for an additional 10% off the sale price, ignoring tax, the price of sale is obtained through the following calculation:
(719 x 0.5) x 0.9 = X
359.5 x 0.9 = X
323.55 = X
Thus, the sale price in the present case would be $ 323.55.
Ariana swims 3/4 at swim practice. Her coach asks her to give her distance in twelfth of a mile. How many twelfth of a mile did Ariana swim?
Answer:
9/12
Step-by-step explanation:
To get the answer from 3/4 of a mile to twelfths of a mile, you must multiply both sides of the fraction to get the denominator to where you want it to be. In this case, to get from 4 to 12 you have to multiply 4 by 3. Then do the same to the numerator and get the answer 9/12.
