Answer:
1. 45
2. 9
3. 11
4. 17
Step-by-step explanation:
The computation is shown below:
Given that
28 checked H
26 checked C
14 checked D
8 checked H and C
4 checked H and D
3 checked C and D
2 checked all.
Based on the above information
N(H)=28
N(C) 26
N(D) 14
N(H∪C) = 8
N(H∪D) = 4
[tex]N(C\cup D)=3[/tex]
[tex]N(H\cup C\cup D)=2[/tex]
We know that
[tex]Total=N(H)+N(C)+N(D)-N(H\cup C)-N(H\cup D)-N(C\cup D)+N(H\cup C\cup D)[/tex]
= 28 + 26 + 14 - 8 - 4 - 3 + 2
= 55
1. The students who didnt check any kind of the box is
= 100 - 55
= 45
2) Students who checked exactly two boxes is
[tex]= N(H\cup C)+N(H\cup D)+N(C\cup D)-3N(H\cup C\cup D)[/tex]
= 8 + 4 + 3 - 6
= 9
3) Students who checked a minimum of two boxes
[tex]= N(H\cup C)+N(H\cup D)+N(C\cup D)-2N(H\cup C\cup D)[/tex]
= 8 + 4 + 3 - 4
= 11
4) Given N(C) = 26
Now we have to deduct N(C∪D) and N(H∪C) as it could be checked aside from the club
= 26 - 8 - 3
= 15
Here the [tex]N(H\cup C\cup D)[/tex] could be deducted twice under both categories so it would be added one time to neutralize
= 15 + 2
= 17

What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
An expression,
48/8 = 42/x
Applying cross multiplication,
x = 42(8)/48
x = 7
Therefore, the value of x is 7.

Four ninths plus one ninth
Answer:
5/9
Step-by-step explanation:
Answer:
5/9
Step-by-step explanation:
4/9 + 1/9
To add fractions, you need a common denominator. You already have a common denominator of 9, so just add the numerators.
4/9 + 1/9 = 5/9
Since there is no common factor of 5 and 9 other than 1, the fraction is already reduced.

If the toss of a coin comes down heads, you win two dollars. If it comes down tails, you lose fifty cents. How much would you expect to gain after 25 tosses (in $ dollars)
Answer:
$30.00
Step-by-step explanation:
Because if you think about it, about half of them are going to be heads and the other half are going to be tails.
hope this helped
We could expect $30.00 to gain after 25 tosses.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
It is given that If the toss of a coin comes down heads, you win two dollars. If it comes down tails, you lose fifty cents.
We need to find How much would you expect to gain after 25 tosses (in $ dollars).
Because if you think about it, you will see that about half of them are going to be heads and the other half are going to be tails.
Therefore, We could expect $30.00 to gain after 25 tosses.

Triangle X Y Z has centroid S. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments X W, Y V, and Z T. The length of line segment T S is 3 m minus 1, the length of line segment S Z is 4 m + 8, and the length of line segment X S is 2 m + 12.
S is the centroid of triangle XYZ.
What is the length of SW?
Answer:
it is indeed B
Step-by-step explanation:
a few years late but its fine right
The length of SW will be 9.5. Each median will be divided into segments by the centroid at a ratio of 2:1.
What is the triangle?A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.
The ratio of the centroid divides each median into segments will be 2:1.
[tex]\rm \frac{SZ}{TS} = \frac{2}{1} \\\\ \frac{4m+8}{3m-1} = \frac{2}{1}\\\\ 4m+8 = 2 (3m-1) \\\\ 4m+8 = 6m -2 \\\\ 2 m = 10 \\\\ m = 5[/tex]

What is the relationship between the length of one leg and the length of the hypotenuse of an isosceles right triangles?
A) Leg = Hypotenuse ∙ √2
B) Hypotenuse = Leg ∙ √2
C) Leg ∙ Hypotenuse = √2
Answer:
B) Hypotenuse = Leg ∙ √2
Step-by-step explanation:
This is a well-known ratio in the 45-45-90 right triangle, but we can derive it.
An isosceles right triangle has two congruent legs forming the right angle and the hypotenuse opposite the right angle. The Pythagorean theorem works since it is a right angle.
Normally, the legs are a and b, and the hypotenuse is c, and we have
a^2 + b^2 = c^2
Here the legs are congruent, so we have a = b.
Substituting a for b, we have
a^2 + a^2 = c^2
2a^2 = c^2
c^2 = 2a^2
c = a√2
Answer: B) Hypotenuse = Leg ∙ √2
Answer:
progably B) Hypotenuse = Leg ∙ √2

Which is an equation for the line that contains (-2,5) and has a slope of -7 ?
7x + y = 33
y=-7x+9
y=-7x-33
7y+y=-9
Answer:
y = -7x - 9Step-by-step explanation:
The standard from of equation of a line is expressed as;
y = mx+c
m is teh slope = -7
c is the intercept
Get the intercept by substituting m = -7 and the point (-2, 5) into the equation;
y = mx+c
5 = -7(-2) + c
5 = 14 + c
c = 5-14
c = -9
Substitute m = -7 and c = -9 into the expression y = mx+c
y = -7x - 9
Hence the required equation of the line is y = -7x - 9
