Since M and N are independent events, [tex]P(M)=P(M|N)=0.71[/tex]
Step-by-step explanation:
Two events A and B are said to be independent when the probability of A happening does not depend on whether B has happened or not.
In other word, this condition can be rewrite as follows:
[tex]P(A|B)=P(A)[/tex]
where
[tex]P(A|B)[/tex] is the probability of A happening given that B has happened
[tex]P(A)[/tex] is the probability of A happening
In this problem, we have:
- M and N are independent events: so M does not depend on whether N occurs or not
Therefore,
[tex]P(M)=P(M|N)[/tex]
- Also, we know that
[tex]P(M|N)=0.71[/tex]
Therefore, it follows that
[tex]P(M)=0.71[/tex]

1. Ms. Morton likes to make weird tasting cookies. She decides to make cookies for friends and her
students. Each friend will get 3 more cookies than each student. She has a total of 112 students
and 12 friends and made of total of 408 cookies for everyone. The system of equations
represents this scenario:
s y=x+3
(112x +12y = 408
Ms. Morton predicts that she will give each friend 4 cookies and each student 7 cookies. Is she correct?
if not, how many cookies will each friend get and each student get?
Morton will give 3 cookies to each student and 6 cookies to each friend
Solution:
Let "x" be the cookies given to each student
Let "y" be the cookies given to each friend
Each friend will get 3 more cookies than each student
Therefore,
cookies given to each friend = 3 + cookies given to each student
y = x + 3 -------- eqn 1
She has a total of 112 students and 12 friends and made of total of 408 cookies for everyone
Therefore, we frame a equation as:
112x + 12y = 408 ---------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 1 in eqn 2
112x + 12(x + 3) = 408
112x + 12x + 36 = 408
124x = 372
x = 3
Substitute x = 3 in eqn 1
y = 3 + 3
y = 6
Thus Morton will give 3 cookies to each student and 6 cookies to each friend
Ms. Morton predicts that she will give each friend 4 cookies and each student 7 cookies. So this is incorrect

a: y=1/2x+2
b: y=-2x+1/2
c: x-2y=-4
d: y-1=1/2(x+2)
Answer:
The Correct option is c. x-2y=-4
Therefore the correct equation for the line passing through the point (-2,1) and having slope m= 1/2 is
[tex]x-2y=-4[/tex]
Step-by-step explanation:
Given:
[tex]Slope = m =\dfrac{1}{2}[/tex]

Which is a correct first step in solving the inequality –4(2x – 1) > 5 – 3x?
The first step in solving the inequality is to distribute –4 to get -8x + 4 > 5 - 3x
Solution:
Given inequality is:
[tex]-4(2x - 1) > 5 - 3x[/tex]
The first step in solving the inequality is to distribute -4 to terms inside the bracket in left side of equation
This is done according to BODMAS rule
According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right
Thus in given inequality, brackets has to solved first
This is done by using distributive property
a(b + c) = ab + bc
Therefore,
[tex]-4(2x - 1) = (-4 \times 2x) +(-4 \times -1) = -8x + 4[/tex]
Thus, the inequality becomes,
[tex]-4(2x - 1) > 5 - 3x\\\\-8x + 4>5-3x\\\\-5x>1\\\\x<\frac{1}{5}[/tex]
Thus solution to given inequality is found
How do you solve this step by step?
Answer:
x = 41
Step-by-step explanation:
To solve this problem, we want to find the value of 'x' by isolating it (separating 'x' from all other numbers).
First, simplify the expression by using the distributive property, where you multiply the number outside the brackets with each term inside the brackets.
Then isolate 'x' by doing reverse operations (on both sides) for every number that is on the same side as 'x'. Reverse operations are opposites (addition and subtraction, multiplication and division) and "cancel out" a number, which "moves" it to the other side.
7(x - 5) = 252 Use the distributive property
7x - 35 = 252 Result of 7 times x and 7 times -5
7x - 35 + 35 = 252 + 35 Add 35 to both sides
7x = 252 + 35 -35+35 on the left side cancelled out. Simplify right side
7x = 287 Continue to isolate 'x'
7x/7 = 287/7 Divide both sides by 7
x = 287/7 Left side cancelled out to be 'x'. Simplify the right side
x = 41 Answer
Check your answer:
Substitute 'x' for 41 in the original equation. Then, make sure that the equation is still balanced. Keep in mind BEDMAS order (brackets, exponents, division, multiplication, addition, subtraction).
7(x - 5) = 252
7(41 - 5) = 252 Simplify inside the brackets first
7(36) = 252 Multiply
252 = 252 Same answer
LS = RS
Since left side (LS) equals (=) right side (RS), the equation is still balanced and we got the correct value for 'x'.
Express 40 as a percentage of 200
Answer:
20 %.
Step-by-step explanation:
(40/200) * 100
= (2/ 10) * 100
= 2 * 10
= 20.
Final answer:
To express 40 as a percentage of 200, you set up a proportion and solve for x, finding that 40 is 20% of 200.
Explanation:
To express 40 as a percentage of 200, we can set up a proportion where 40 is to 200 as x is to 100 (since percentages are out of 100). This gives us the proportion 40/200 = x/100. Solving for x, we multiply both sides by 100 to isolate x on one side of the equation. This gives us x = (40 × 100) / 200.
Next, we perform the multiplication and division: x = 4000 / 200. Simplifying that, we get x = 20. Therefore, 40 is 20% of 200.

Answer:
1. Using the Pythagorean theorem.
2. Using the ratio 1 : 1 : √2.
Step-by-step explanation:
There are two options to find the value of x:
1. Using the Pythagorean theorem:
Hypotenuse = 5√2 inches and legs are equal in a 90 - 45 - 45 triangle like this.
Hypotenuse² = Leg² + Leg²
(5√2)² = 2Leg²
50 = 2Leg²
50/2 = Leg²
Leg² = 25
√Leg² = √25
Leg = 5 inches ⇒ x = 5
2. Using the ratio 1 : 1 : √2, this way:
1 : 1 : √2
x : x : 5√2
x = 5√2/√2
x = 5 and let's recall that in a 90 - 45 - 45 triangle legs are equal, therefore. ratio is:
5 : 5 : 5√2
Last night, 4 friends went out to dinner at a restaurant. They split the bill evenly. Each friend paid $12.75 for his or her meal and each left the same amount for a tip, t. The total dinner bill including the tip was $61. What equation could you use to describe the situation?
Final answer:
To create the equation representing the situation, calculate the total meal cost by multiplying each friend's share by four and then add four times the tip to equal the final bill of $61. The equation is 4 times $12.75 + 4 imes t = $61.
Explanation:
To solve the problem using an equation, we need to consider the cost of each meal and the tip each friend left. Four friends each paid $12.75 for their meal, which gives us the cost of the meals alone: 4 times $12.75 = $51. The tip, t, needs to be added four times (once for each friend) to the total cost of the meals to reach the final bill of $61.
Therefore, the equation to represent the situation would be: 4 times $12.75 + 4 times t = $61.
Once we have the equation, we can solve for the tip, t, to find out how much each friend left for the tip.

The sum of the first and third of three consecutive integers is 136. Find the three even integers
The three even integers are 66, 68 and 70
Solution:
Let the three consecutive even integers be x, x + 2, x + 4
Let the first integer be x
Let the second integer be x + 2
Let the third integer be x + 4
Given that, sum of the first and third of three consecutive integers is 136
Sum of first and third integer = 136
x + x + 4 = 136
2x + 4 = 136
2x = 136 - 4
2x = 132
x = 66
Thus the consecutive integers are:
first even integer = x = 66
second even integer = x + 2 = 66 + 2 = 68
third even integer = x + 4 = 66 + 4 = 70
Thus the three even integers are 66, 68 and 70
