Answer: 0.0256 which converts to 2.56%
Explanation:
Assuming each event is independent of one another, the probability of having four people in a row order a salad is 0.40^4 = 0.0256 = 2.56%
If for instance you only wanted to know the probability that the next three people would order salad, then you would compute 0.40^3 = 0.064 = 6.4%

V = lwhV = 16*9*6 + 2*6*9 = 972 m³A student fit the line shown below to the data in the scatter plot. Which statement about the student's line is true?
A. It is a good fit because there are the same number of points above the line as below it.
B. It is a good fit because all of the points are on or below the line.
C. It is not a good fit because there are no points on the line.
D. It is not a good fit because only one point is on the line.
Answer:
C. It is not a good fit because there are no points on the line.
Step-by-step explanation:
In order for a line to be a good fit for a data set represented as a scatterplot, the line must follow the general trend of the data in the scatterplot. This line does not follow the general trend of the data on the scatterplot, thus option (C) is the best statement to describe the situation.
C. It is not a good fit because there are no points on the line.

A 8/15
B 8/17
C 15/8
D 15/17
Answer:
[tex]\text{D) }\frac{15}{17}[/tex]
Step-by-step explanation:
In any right triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse of the triangle (o/h).
Therefore, we have:
[tex]\sin 62^{\circ}=\boxed{\text{D) }\frac{15}{17}}[/tex]

Tim has already earned $30 mowing lawns. He earns $10 per lawn. Write and solve an inequality to determine how many more lawns he will have to mow to have at least $75 for a new lawnmower. Interpret the solution.
Answer:
Tim needs to mow 5 more lawns in order to buy his new lawnmower
Step-by-step explanation:
1) Tim has already mowed $30 worth of lawns
2) Tim makes $10 per mow
4) Tim needs to make $75 total for his new mower
5) $75 - $30 = $45
6) Tim needs to make $45 in order to get his new mower
7) 5 x 10 = 50
8) Tim needs to mow 5 lawns in order to make over $45
9) If Tim only mowed 4 lawns he would make $40 and still be $5 short

Solve -7g - 2 = - 30. Show your steps.
Please show your work in the box provided
Answer:
g=4
Step-by-step explanation:
Move all terms not containing g to the right side of the equation.
-7g-2=-30
-7g=-28
g=-28/-7
g=4
hi ^^
---------
Here's your answer: g=4
-----------------------------------
Now the steps: Equation: −7g−2=−30
· Add 2 to both sides.
−7g=−30+2
· Add −30 and 2 to get −28.
−7g=−28
· Divide both sides by −7.
g= −7 /−28
· Divide −28 by −7 to get 4.
g=4

Elena has written 3 sports books for kids. One book is about soccer, one is about baseball, and one is about basketball. Elena has sold a total of 3,017 of the books in local bookstores. She sold 3 times as many copies of the soccer book as the baseball book. She sold the same number of copies of the basketball book as the soccer book. How many copies of the soccer book has she sold?
Answer:
1293 soccer books
Step-by-step explanation:
The tricky part about questions like this is: how do I assign variables to the three types of book?
You get a clue from the sentence, "She sold 3 times as many copies of the soccer book as the baseball book." The number of soccer books is being described by referring TO the number of baseball books. Pick a variable and assign it to the item being REFERRED TO!
x = number of baseball books
Then 3x = number of soccer books. The number of basketball books is the same, so 3x = number of basketball books. Here's the list...
x = number of baseball books
3x = number of soccer books
3x = number of basketball books
The total of these is 3017, so
x + 3x + 3x = 3017
7x = 3017
x = 431
Ah! But don't forget to look back at the question: it asks for the number of SOCCER books! That's 3x, so 3(431) = 1293.

Answer:
22.75
Step-by-step explanation:
i used a caculator
Answer:
22.75
Step-by-step explanation:
First, our equation is : Y = P% * X
Input your numbers
Y = 35% * 65
Now we must convert our percent to a decimal:
p = 35%/100 = 0.35
Now you can multiply them
Y = 0.35 * 65
Y = 22.75

sammy is eleven less than five times Jaime's age. if the sum of their ages is 55, how old is each girl? please help me if i dont get this done soon moms gonna be super mad
Answer:
Jaime = 11
Sammy = 44
Step-by-step explanation:
It is given that Sammy is eleven less than five times Jaime's age. Use parameter (S) to represent Sammy's age, and parameter (J) to represent Jaime's age. Form an equation based on this given information:
S = 5J - 11
It is given that the sum of the two girl's ages is (55), use an equation to represent this.
S + J = 55
Substitute in the expression for the value of (S) in terms of (J),
(5J - 11) + J = 55
Simplify,
6J - 11 = 55
Inverse operations,
6J - 11 = 55
6J = 66
J = 11
Backsolve for the value of (S), substitute in the value of (J) into the equation for (S) and solve,
S = 5(J) - 11
S = 5(11) -11
S = 55 - 11
S = 44
x = -3y+6
2x+8y= -12
i cannot solve this equation but it needs to be solved by substitution.
Answer:
x + 3y = 6
2x + 8y = -12
substracting first equation from the second will give us
x - 5y = -18
subtracting the first one from this will give us
-8y = -24
y = 3
x = -3
By substitution method, the values of x and y are 42 and -12 respectively.
What is Linear Equations?Linear equations are types of equations which have a left and a right hand side connecting with an '=' sign consisting of one or more variables which have the highest degree of 1.
We have linear equations,
x = -3y + 6
2x + 8y = -12
We have to solve this by substitution.
Substitute the value of x = -3y + 6 in the equation 2x + 8y = -12.
2(-3y + 6) + 8y = -12
By distributive property, a(b + c) = a b + a c
(2 × -3y) + (2 × 6) + 8y = -12
-6y + 12 + 8y = -12
2y + 12 = -12
2y = -12 - 12
2y = -24
y = -24/2
y = -12
x = -3y + 6 = (-3 × -12) + 6 = 36 + 6 = 42
Hence the values of x and y are 42 and -12.

Mike is training for a cross country bike ride. He rides his bike 60 miles, 66 miles, 70 miles, 60 miles, and 51 miles on the first five days of his training. How many miles does he need to ride on day 6 to average(mean) of 59 miles per day?
Answer:
47 miles
Step-by-step explanation:
The formula for Mean = Sum of values/Number of values
Number of values is 6
From the above question, we are only given 5 values,
The 6th value is represent as= x
Hence,
60 miles + 66 miles+ 70 miles+ 60 miles+ 51 miles + x miles/6 = 59 miles
Cross Multiply
60 miles + 66 miles+ 70 miles+ 60 miles+ 51 miles + x miles = 6 × 59 miles
307 miles + x miles = 354 miles
x miles = 354 miles - 307 miles
x miles = 47 miles
Therefore, the number of miles he need to run on day 6 is 47 miles

The probability that roger wins a tennis tournament (event a) is 0.45, and the probability that Stephan wins the tournament (event B) is 0.40. The probability of Roger winning the tournament, given that Stephan wins, is 0. The probability of Stephan winning the tournament given that Roger wins, is 0. Given this information, which statement s true?
Answer:
3.Events A and B are not independent because P(A|B) ≠ P(A).
Step-by-step explanation:
Given this information, which statement is true?
1.Events A and B are independent because P(A|B) = P(A).
2.Events A and B are independent because P(A|B) ≠ P(A).
3.Events A and B are not independent because P(A|B) ≠ P(A).
4.Events A and B are not independent because P(A|B) = P(A).
Solution:
Two events A and B are independent if A occurring does not change the probability of B. For independent events:
P(A ∩ B) = P(A) * P(B)
Hence: P(A/B) = P(A ∩ B) / P(B) = P(A) * P(B) / P(B) = P(A)
Let event A represent the probability that roger wins a tennis tournament and event B represent the probability that Stephan wins a tennis tournament.
Therefore:
P(A) = 0.45, P(B) = 0.4
The probability of Roger winning the tournament, given that Stephan wins, is 0. Hence, P(A/B) = 0
P(A/B) = P(A∩B) / P(B)
0 = P(A∩B) / 0.4
P(A∩B) = 0
The probability of Stephan winning the tournament given that Roger wins, is 0. Hence P(B/A) = 0
P(B/A) = P(B∩A) / P(A)
0 = P(B∩A) / 0.4
P(B∩A) = 0
Therefore since P(A∩B) = P(B∩A) =0, this means that event A and event B are mutually exclusive. That is both events cannot occur at the same time.
Events A and B are not independent because P(A|B) ≠ P(A).
