What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The data of mathematics students is,
60 study French, 30 study French and German
55 study German, 25 study French and Russian
75 study Russian, 35 study German and Russian
12 students study all the three languages.
Now,
Let F, G, R denote the set of students studying French, German and Russian respectively.
And, The data of mathematics students is,
n (F) = 60, n (F ∩ G) = 30
n (G) = 55, n (F ∩ R) = 25
n (R) = 75 , n (G ∩ R) = 35
n (F ∩ G ∩ R) = 12
Since, We know that;
⇒ n (FUGUR) = n (F) + n (G) + n (R) - n (F ∩ G) - n (F ∩ R) - n (G ∩ R)
+ n (F ∩ G ∩ R)
Substitute all the values, we get;
⇒ n (FUGUR) = n (F) + n (G) + n (R) - n (F ∩ G) - n (F ∩ R) - n (G ∩ R)
+ n (F ∩ G ∩ R)
⇒ n (FUGUR) = 60 + 55 + 75 - 30 - 25 - 35 + 12
⇒ n (FUGUR) = 112
Thus, The value of n (FUGUR) will be;
⇒ n (FUGUR) = 112

Answer:
Step-by-step explanation:
10-4=6
9-(x)=6
9-6=(x)
(x) = 3
The answer is 3
Answer:
Missing number = 3
Step-by-step explanation:
Forming the equation,
→ 10 - 4 = 9 - x
→ x = missing number
Now the value of x will be,
→ 10 - 4 = 9 - x
→ 6 = 9 - x
→ -x = 6 - 9
→ -x = -3

The length and width of a rectangle are 36 and 30 yard respectively.
What is perimeter?Its the sum of length of the sides used to made the given figure.
We are given that width of a rectangle is 6 yards less than the length. The perimeter is 132 yards.
Therefore, the perimeter = (2 x length)+(2 x width)
The length = 6 + w
Hence, we have;
132 = (2(6 + w))+(2w)
132 = 12 + 2w + 2w
132 = 12 + 4w
120 = 4w
w = 30
Length = 36 yard.

If a person travels at a speed of 28 m/s for 10 seconds, how far have they traveled?
It is a uniform rectilinear movement which is one in which an object moves in a straight line, in one only direction, with a constant speed.

DIG DEEPER A group of friends visits a movie theater.
A menu of Royal Cinemas shows cost of tickets and refreshments. The cost of daytime and evening tickets are 5 dollars and 7.50 dollars respectively. The cost of small, medium, and large drinks are 1.75 dollars, 2.75 dollars, and 3.50 dollars respectively. The cost of small and large popcorns are 3 dollars and 4 dollars respectively.
Each person buys a daytime ticket and a small drink. The group shares 2 large popcorn. What is the average cost per person when there are 4 people in the group?
The average cost per person when there are 4 people in the group is of:
$8.75.
How to obtain the average cost per person?The average cost per person represents the mean cost per person in the data-set.
The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
Hence, the average cost per person in this problem is obtained as the division of the total spending by four, as there are four people.
The total spending is obtained as follows:
Four daytime tickets -> 4 tickets of 5 dollars.Four small drinks -> 4 drinks of 1.75 dollars.Two large popcorns -> 2 popcorns of 4 dollars.Hence the numeric value of the total spending is of:
4 x (5 + 1.75) + 2 x 4 = $35.
Thus the average spending per person is of:
$35/4 = $8.75.

The final interval notation is F ∩ H = [7, 4] & F ∪ H = [-∞, ∞].
What is the interval notation?

We have,
F and H are sets of real numbers defined as follows.
F = { v l v < 4}
H = { v l v ≥ 7}
F is the set of all real numbers that are less than or equal to 4. H is the set of real numbers greater than 7.
F U H is the union (or combination) of the two sets, so it is the set of all real numbers that are less than equal to 3 or greater than 6:
F ∩ H is the set of real numbers that are in both sets; but since F is less than or equal to 4 and H is greater than 7, there are no numbers that are in both sets. Hence the answer is the empty set, Ø:

What is a expression? What is a mathematical equation? What is Probability?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. The formula to calculate the probability of occurrence of an event 'A' can be written as -
P(A) = n(A)/n(S)
where -
n(A) = Number of outcomes favorable to event A.
n(S) = Total number of outcomes
Given are two dices rolled.
The total number of favorable outcomes can be calculated as -
[a] = (1,1) to (1,6) = 6
[b] = (2,1) to (2,6) = 6
[c] = (3,1) to (3,6) = 6
[d] = (4,1) to (4,5) = 5
[e] = (5,1) to (5,4) = 4
[f] = (6,1) to (6,3) = 3
n(A) = [a] + [b] + [c] + [d] + [e] + [f] = 6+6+6+5+4+3 = 30
n(S) = 36
So, the probability of occurrence of an event 'A' -
P(A) = n(A)/n(S)
P(A) = 30/36
P(A) = 5/6
Therefore, the probability that the total showing is less than 10 is 5/6.

Malcolm should place the decimal point immediately after one (1) or before three (3) as follows: 8.25/6 = 1.375.
What is a quotient?In Mathematics, a quotient can be defined as a mathematical expression that is simply used to represent the division of a number by another number.
As a general rule, the smaller the divisor (denominator) of a mathematical expression, the larger would be the quotient. This ultimately implies that, a quotient would be large when the divisor (denominator) of a mathematical expression is small.
On the other hand (conversely), a quotient would be small when the divisor (denominator) of a mathematical expression is large.
Based on Malcom's calculations, he forgot to place the decimal point in the following expression;
8.25/6 = 1375
Next, we would determine the maximum value of this quotient;
8.25/6 = 12/6
8.25/6 = 2
Therefore, the whole number part for this decimal number would be one (1) and as such, the decimal point must be placed immediately after 1 as follows;
