11=3x-4
x=....
thanks all
Answer:
the value of x is 5 .
Step-by-step explanation:
In order to find the value of x, you have to move the unrelated terms to the other side by adding 4 to both sides :
[tex]11 = 3x - 4[/tex]
[tex]11 + 4 = 3x - 4 + 4[/tex]
[tex]15 = 3x[/tex]
Next, you have to divide it by 3 :
[tex]3x = 15[/tex]
[tex]x = 15 \div 3[/tex]
[tex]x = 5[/tex]

Find the area of a triangle with a =4, b =6, and c =8.
a. 10.2 units 2
b. 8.4 units 2
C.12.4 units
d. 11.6 units 2
Answer:
d
Step-by-step explanation:
Given 3 sides of the triangle the area (A) can be calculated using Hero's formula.
A = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
where s is the semi perimeter of the triangle
s = [tex]\frac{a+b+c}{2}[/tex] = [tex]\frac{4+6+8}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9 , thus
A = [tex]\sqrt{9(9-4)(9-6)(9-8)}[/tex]
= [tex]\sqrt{9(5)(3)(1)}[/tex]
= [tex]\sqrt{135}[/tex]
≈ 11.6 units² → d

The center is at (0,2). So (h,k) = (0,2) leads to h = 0 and k = 2.
The radius is 2 units, meaning r = 2.
Plug h = 0, k = 2, r = 2 into the formula below and simplify

Hey, can anyone help me? My math question is: "What sort of information can you get from conditional frequencies that you couldn't get by just looking at the relative frequencies?"
Thanks :)
Answer: Conditional frequencies enables users to get more specific information when analyzing a dataset.
Step-by-step explanation: Frequency refers to the count of occurrence of a particular variable.
Relative frequency is obtained by taking the ratio of the counts a particular variable and the total counts and of all available variables in the experiment or data.
Conditional Frequency allows us to input additional constraints to our frequency counts, especially in a two-way table. Enabling us to get more specific information by using conditional statements.

Which of the following statements is true, given
Answer:
ALL of themStep-by-step explanation:
Hope this helps!The correct answer by using divisibility rules is:
a) Exactly one of these statements is false.
Statement 1: If two numbers are co-primes, at least one of them must be prime.
This statement is true. Two numbers are considered co-prime if their greatest common divisor (GCD) is 1. If both numbers are not prime, it means they have factors other than 1 and themselves. In that case, their GCD would be greater than 1, contradicting the definition of co-prime numbers. Therefore, at least one of the two co-prime numbers must be prime.
Statement 2: If a number exactly divides two numbers, then it must also divide their sum.
This statement is false. Just because a number divides two other numbers, it does not necessarily mean that it will divide their sum. For example, consider the numbers 6, 8, and 14. 6 and 8 are both divisible by 2, but their sum, 14, is not divisible by 2.
Based on the analysis above, exactly one of these statements is false.
Therefore, the correct answer by using divisibility rules is:
a) Exactly one of these statements is false.

Answer:
Third side is 9m.
Step-by-step explanation:
In a right triangle the square on the hypotenuse is equal to the sum of the squares on the other two sides.
15 x 15= 225m2
12 x 12 = 144m2
225 - 144 = 81m2 and the length of the third side is square root of 81, which would be 9m as your final answer.
Answer:
Follow the Pythagoreas theorm. You typically need to find [tex]C^2[/tex], which is the hypotonuse, but because we already know this, we can rearrange the equation to make sense.
Personally, I like to substitute with non-related numbers, such as 1 and 2. In the following example, the sides are 1 unit, 2 units, and 5 units. First, I like to figure out the sum of [tex]a^2[/tex] and [tex]b^2[/tex] .
EX: [tex]1^2+2^2= 5[/tex]
[tex]25^2=5[/tex]
I can rearrange this so that one leg and the hypotenuse are on the same side:
[tex]25^2-1^2=2^2[/tex]
Now I can take out the example numbers, and substiture in the variables.
[tex]c^2-a^2=b^2[/tex]
Now all I have to do is fill in the known variables!
[tex]15^2-12^2=b^2[/tex]
Solve!
[tex]225-144=80[/tex]
We're not done- we have to find the square root of 81!
It's 9m!
Finally, we can check our work by plugging [tex]A^2[/tex] and [tex]B^2[/tex] into the normal equation. It checks out!
[tex]12^{2} +9^{2} = 15^{2} \\=225 =225\\225=225[/tex]

The height of a parallelogram is one-third its base. If the area of the parallelogram is 363 square inches, find its base and height. (Draw a diagram.)
Answer:
Height = 11 inches
Base = 33 inches
Step-by-step explanation:
In this question, we are asked to find the height and base of a parallelogram given the area of the parallelogram.
From the question, we are told that height is 1/3 of base. This means that base is 3 times the height
So if we represent the height with variable h, then the base is 3h
Mathematically the area of a parallelogram can be calculated by the formula
A = bh
Thus ,
363 = h * 3h
3h^2 = 363
divide through by 3
h^2 = 121
h = √121
h = 11 inches
since b = 3h , then b = 3 * 11 = 33 inches

Today, Isaac needs to walk his dog, water the garden, and feed his fish. DDD is the number of minutes it takes to walk his dog, GGG is the number of minutes it takes to water the garden, and FFF is the number of minutes it takes to feed his fish. The expression G+(D+F)G+(D+F)G, plus, (, D, plus, F, )describes the total number of minutes it takes Isaac to do all three tasks. We can also use the expression (G+D)+F(G+D)+F(, G, plus, D, ), plus, F to represent the same quantity. Match each amount in the situation with the expression that represents it. For reference: The dog is an animal, and he needs to go outside to walk. The garden is a bunch of plants (not an animal), and it is outside. The fish is an animal, and she lives in a water tank inside.

2.5 kg of potatoes cost £1.40
Work out the cost of 4.25 kg of potatoes.
Step-by-step explanation:
if 2.5kg=£1.40
then 4.25kg=!
then cross multiply
4.25×1.40=2.5
5.95÷2.5kg=£2.38
Answer:
4.25 kg = £2.38
Step-by-step explanation:
The formula for working out the price per quantity is : [tex]\frac{Price}{Amount}[/tex]
To work this out you would first need to convert the mass of 2.5 kilograms into grams. You can do this by multiplying 2.5 by 1000, this gives you 2500 grams. This is because 1 Kg is equivalent to 1000 g and so by multiplying it by 1000 we are converting the kilograms into grams.
Then the next step is to divide the price of £1.40 by the quantity of 2500, this gives you 0.00056. This is because we are working out how much it costs for 1 g of potatoes.
Now that we know the price per gram we can now start working out the price of 4.25 kg. You can do this by first multiplying the mass of 4.25 kg by 1000, this gives you 4250. This is because we are converting the kilograms into grams.
The final step is to multiply the price per gram which is 0.00056 by 4250, this gives you £2.38.
1) Multiply 2.5 by 1000.
[tex]2.5*1000=2500[/tex]
2) Divide 1.40 by 2500.
[tex]1.40/2500=0.00056[/tex]
3) Multiply 4.25 by 1000.
[tex]4.25*1000=4250[/tex]
4) Multiply 0.00056 by 4250.
[tex]0.00056*4250=2.38[/tex]
If P(A)=35, P(B)=13, and P(A∩B)=18, are A and B independent?
Select the option that provides both the correct answer and the correct reason.
No, because 35(13)≠18.
Yes, because 35(13)=18.
Yes, because 35+13=18.
No, because 35÷13≠18.
No, because 35+13≠18.
Answer:
P(A) x P(B) = 35 x 13 = 455
P(A∩B) = 18
=> P(A) x P(B) ≠ P(A∩B).
=> A and B are not independent.
=> Option A (No, because 35(13)≠18) is correct.
Hope this helps!
:)
A and B are not independent because 35(13)≠18), the correct option is A
What is the independent probability?Independent events and probability can be defined as those occurrences that are not dependent on any specific event.
P(A)=35, P(B)=13, and P(A∩B)=18, are A and B independent.
It is to note here that A and B are the odd number outcome and multiples of 3 respectively. So, P (A ∩ B) = 18
P(D│E) = P (D ∩ E)/ P(B)
P(D│E) = 18/13
Here P(D) = P(D│E) = 18/13, which entails that the occurrence of event E will not be affected by the probability of event D’s occurrence.
Taking A and B as independent events, then P(D│E) = P(D).
Here, A and B are not independent because 35(13)≠18), the correct option is A.

Tristan and Anthony go to the movie theater and purchase refreshments for their friends. Tristan spends a total of $132.00 on 10 drinks and 7 bags of popcorn. Anthony spends a total of $102.00 on 2 drinks and 14 bags of popcorn. Write a system of equations that can be used to find the price of one drink and the price of one bag of popcorn. Using these equations, determine and state the price of a bag of popcorn, to the nearest cent.
Answer:
Popcorn=$6
Step-by-step explanation:
1) Setting variables
d= price of drinks
p= price of popcorn
2) Writing the system of equations
10d+7p=132
2d+14p=102
3) Simplifying one equation
2d=102-14p
d=51-7p
4) Solving the other equation by plugging the first equation in
d=51-7p
10d+7p=132
10(51-7p)+7p=132
510-70p+7p=132
510-63p=132
63p=378
p=6
5) Substituting p=6 into the first equation
d=51-7p
d=51-42
d=9
