Where is the blue dot on the number line?
In a large school, it was found that 77% of students are taking a math class, 74% of student are taking an English class, and 70% of students are taking both. Find the probability that a randomly selected student is taking a math class or an English class. Write your answer as a decimal, and round to 2 decimal places if necessary. Find the probability that a randomly selected student is taking neither a math class nor an English class. Write your answer as a decimal, and round to 2 decimal places if necessary.
Answer:
0.81 = 81% probability that a randomly selected student is taking a math class or an English class.
0.19 = 19% probability that a randomly selected student is taking neither a math class nor an English class
Step-by-step explanation:
We solve this question working with the probabilities as Venn sets.
I am going to say that:
Event A: Taking a math class.
Event B: Taking an English class.
77% of students are taking a math class
This means that [tex]P(A) = 0.77[/tex]
74% of student are taking an English class
This means that [tex]P(B) = 0.74[/tex]
70% of students are taking both
This means that [tex]P(A \cap B) = 0.7[/tex]
Find the probability that a randomly selected student is taking a math class or an English class.
This is [tex]P(A \cup B)[/tex], which is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
So
[tex]P(A \cup B) = 0.77 + 0.74 - 0.7 = 0.81[/tex]
0.81 = 81% probability that a randomly selected student is taking a math class or an English class.
Find the probability that a randomly selected student is taking neither a math class nor an English class.
This is
[tex]1 - P(A \cup B) = 1 - 0.81 = 0.19[/tex]
0.19 = 19% probability that a randomly selected student is taking neither a math class nor an English class

Answer:
160
Step-by-step explanation:
you replace x with 8 and replace y with 10
Whenever the numbers are close together such as "xy2" it mean you're multiplying
so whwn you multiply 8 * 10 * 2 you would get 160

The simplified expression in the form 5^n is 5^−1×6.
What is a fraction?A fraction represents a part of a number or any number of equal parts.
A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.
We are given that;
Form=5 ^ n
Now,
To simplify the expression, we need to first rewrite the fractions with a common denominator of 60: (5/10)/(5/12)=(5×6)/(10×6)÷(5×5)/(12×5)=(30/60)/(25/60)
Then we need to invert the second fraction and multiply: (30/60)/(25/60)=(30/60)×(60/25)=30/25
Then we need to simplify the fraction by dividing both numerator and denominator by 5: 30/25=(30÷5)/(25÷5)=6/5
Finally, we need to rewrite the fraction in the form of 5n
by using the property that a/b=a×b−1
So we have: 6/5=6×5−1=50×6×5−1=50−1×6=5−1×6
Therefore, by the fraction the answer will be 5^−1×6.

Answer:
The length of the missing side is 8.5 ft
Step-by-step explanation:
To find the length of the missing side, we can use the Pythagorean theorem which states [tex]a^2 + b^2 = c^2[/tex] where c is the length of the longest side of a right-angle triangle while a and b are the other two sides. Note that the Pythagorean theorem ONLY applies to right-angle triangles.
[tex]a^2+b^2=c^2\\(6)^2+(6)^2=36+36=72=c^2\\\\c=\sqrt{72}= 8.48[/tex]
Rounding to the first decimal place, we get c = 8.5ft
Find total surface area of the pyramid.
Answer choices
A.144 inches squared
B.1150 inches squared
C.170 inches squared
D.180 inches squared
Answer:
D) 180 inches²
SEE NOTE*
Step-by-step explanation:
Base = 10x10=100
Each triangle = 1/2x10x4=20
20x4=80
100+80=180
* This may be a trick question. This pyramid CANNOT exist. If the base is 10 inches, the height of the triangles cannot be 4 inches. They must be more than 5.
Jorge walked 25 steps north. Then he walked 75 steps south. What’s Jorge final position
Well if Jorge's motion can be described by vectors then he first went +25 steps then -75 steps which means he did -50 steps in total. His position is thus 50 steps to the south of the original position.

the two forces 132-lb and 88 lbs are applied to opposite ends of a 15 foot lever. How far from the greater force must the fulcrum be placed so that the lever is balanced?
The fulcrum should be. feet from the greater force.
ignore the weights of the lever
Answer:
6 feet from the greater force
Step-by-step explanation:
X = length from greater weight to fulcrum
132X = 88(15-X)
132X = 1320-88X
220X = 1320
X = 6

A survey of 285 adults found that during the last year, 75 traveled by plane but not by train, 55 traveled by train but not by plane, 30 traveled by bus but not by plane or by train, 70 traveled by bus and plane, 35 traveled by all three, and 215 traveled by plane or train. How many did not travel by any of these modes of transportation
Answer:
40
Step-by-step explanation:
Given that
Total number of adults, U = 285
Number of plane travellers, P = 75
Number of train travellers, T = 55
To find the number of people that didn't travel by any means of transportation listed in the question, then we say
Total number of adults minus number people who traveled by plane or train minus number of people who traveled by bus but not by plane or train.
This means that number of people who didn't travel by any of the three means of transportation, N =
N = U - pt - b
N = 285 - 215 - 30
N = 40
Therefore, the total number needed is 40
