Answer:
The value of x = 11/10 or 1.1
Step-by-step explanation:
5x+3/-2 =4
=> 5x -3/2 = 4
=> 5x = 4 + 3/2
=> 5x = (8+3)/2
=> 5x = 11/2
=> x = 11/10 or 1.1

What is the spheres valume.
Answer: 972π in³
Step-by-step explanation:
We will use the proper formula to solve for the volume of the sphere.
-> The radius (r) is half the diameter. 18 in / 2 = 9 in
V = [tex]\frac{4}{3}[/tex]πr³
V = [tex]\frac{4}{3}[/tex]π(9)³

what is the interquartille range of the given data set
11, 12, 14, 15. 18. 19. 21, 23. 25, 55
A. 25
B. 9
C. 44
Answer: B. 9
Step-by-step explanation:
First, find the median of the data set. This set has an even number of points, so find the average between the two middle points: 18 and 19. 18+19 = 37. 37/2 = 18.5. The median is 18.5.
Now, to find the lower quartile, find the median of the lower half of the data set {11, 12, 14, 15, 18}. The number in the middle is 14. The lower quartile is 14.
To find the upper quartile, find the median of the upper half of the data set {19, 21, 23, 25, 55}. The number in the middle is 23. The upper quartile is 23.
To find the interquartile range, subtract the lower quartile from the upper quartile. 23-14 = 9. The interquartile range is 9.

what is the formula of quadratic using factoring. And explain the formula?
Answer:
Steps to factorize quadratic equation ax2 + bx + c = 0 using completeing the squares method are: Step 1: Divide both the sides of quadratic equation ax2 + bx + c = 0 by a. Now, the obtained equation is x2 + (b/a) x + c/a = 0. Step 2: Subtract c/a from both the sides of quadratic equation x2 + (b/a) x + c/a = 0.

Step-by-step explanation:
2 times 4 is 8
Step-by-step explanation:
remember, when multiplying the same base with different exponents, we add the exponents.
when putting exponents to the power of exponents, we multiply the exponents (as simplified shortcut of all the additions we would actually have to do).

What is the volume of the enclosure to the nearest whole number? the volume is approximately ft3. how can the density of birds in the enclosure be found? divide the . what is the number of birds per cubic foot to the nearest hundredth? the density is approximately birds per cubic foot.
The volume of the conical enclosure is approximately 871 ft³.
The density of the birds in the enclosure is number of birds / volume
The number of bird per cubic ft is 0.04822043628 birds per cubic foot
Volume of a conevolume of a cone = 1 / 3 πr²h
where
r = radiush = heightTherefore,
v = 1 / 3 × 3.14 × 8² × 13
v = 1 / 3 × 3.14 × 64 × 13
v = 2612.48 / 3
v = 870.826666667
v = 870.83 ft³
The density of the birds in the enclosure is the mass of the birds divided by the volume of the enclosure.

What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.
What is the formula of combination?[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]
For given question,
We have been given five number cards.
Two of the five cards are picked at random.
Using combination formula the possible number of outcomes would be,
[tex]^5C_2\\\\=\frac{5!}{2!(5-2)!} \\\\=10[/tex]
So, n(S) = 10
Let event A : the total of the two numbers is more than 32
A = {(19, 14), (19, 22), (13, 22), (14, 22)}
So, n(A) = 4
Using the formula for probability,
[tex]\Rightarrow P(A)=\frac{n(A)}{n(S)} \\\\\Rightarrow P(A)=\frac{4}{10}\\\\\Rightarrow P(A)=\frac{2}{5}[/tex]
Therefore, the probability that the total of the two numbers is more than 32 = [tex]\frac{2}{5}[/tex]

Which is an example of the commutative property of addition?
3+5m=5m+3
3+5m=(3+5)m
3+ 5m= 3 + (1 + 4)m 3+5m=3m+5
Answer:
3 + 5m = 5m + 3What is the communitive property of addition?The commutative property of addition means that it does not matter what order in which you add numbers. You will get the same answer either way. It is represented as a + b = b + a, in which a and b are real numbers. However, the property is not limited to two numbers.
How would the communitive property of addition be applied to the expression 3 + 5m = 5m + 3?1) Rearrange terms
3 + 5m = 5m + 3
5m + 3 = 5m + 3
2) Subtract 3 from both sides
5m + 3 = 5m + 3
5m + 3 - 3 = 5m + 3 - 3
3) Simplify
- Subtract the numbers
5m + 3 - 3 = 5m + 3 - 3
5m = 5m + 3 - 3
- Subtract the numbers
5m = 5m + 3 - 3
5m = 5m
4) Subtract 5m from both sides
5m = 5m
5m - 5m = 5m - 5m
5) Simplify
- Combine like terms
5m - 5m = 5m - 5m
0 = 5m - 5m
- Combine like terms
0 = 5m - 5m
0 = 0
This means it has infinite solutions.
