Answer:
The coach can choose a lineup of 11 players in 6,047,981,701,347 different ways.
Step-by-step explanation:
Since the varsity soccer team has 20 players, and three of the players are trained to be goalies while the remaining 17 can play any position, and only 11 players can be on the field at once, and the coach wants to make sure there is exactly one goalie on the field, to determine how many ways can the coach choose a lineup of 11 players if exactly 1 player must be a goalie the following calculation has to be made:
3 x 17 ^ 10 = X
3 x 2,015,993,900,449 = X
6,047,981,701,347 = X
Therefore, the coach can choose a lineup of 11 players in 6,047,981,701,347 different ways.

If the temperature at which a certain compound melts is a random variable with mean value 135°C and standard deviation 3°C, what are the mean temperature and standard deviation measured in °F? [Hint: °F = 1.8°C + 32.]
Answer:
The mean in ºF is of 275 and the standard deviation is of 37.4.
Step-by-step explanation:
We apply the conversion formula for both measures, the mean and the standard deviation.
Mean value 135°C
In ºF:
[tex]F = 1.8(135) + 32 = 275[/tex]
Standard deviation 3°C:
In ºF:
[tex]F = 1.8(3) + 32 = 37.4[/tex]
The mean in ºF is of 275 and the standard deviation is of 37.4.
Compare the steps to find the distance between two points on the coordinate plane by first using the Pythagorean Theorem and then using the Distance Formula.

The length of each of the legs of an isosceles triangle is represented by the
expression 6x – 2 inches. The length of the base of the isosceles triangle is
represented by the expression 3x + 1 inches. The perimeter of the isosceles
triangle is 42 inches. What is the length of the base?
Answer:
10 inches
Step-by-step explanation:
6x-2+6x-2+3x+1=42
12x-4+3x+1=42
15x-3=42
15x=45
x=3
Plug x=3 into 3x+1
3*3+1

Look at the right-angled triangle ABC.
32°
The square fits exactly inside the triangle.
Work out the sizes of angles x, y and z.
Answer:
∠x = 90°
∠y = 58°
∠z = 32°
Step-by-step explanation:
he dimensions of the angles given are;
∠B = 32°
Whereby ΔABC is a right-angled triangle, and the square fits at angle A, we have;
∠A = 90°
∠B + ∠C = 90° which gives
32° + ∠C = 90°
∠C = 58°
∠x + Interior angle of the square = 180° (Sum of angles on a straight line)
∠x + 90° = 180°
∠x = 90°
∠x + ∠y + 32° = 180° (Sum of angles in a triangle)
90° + ∠y + 32° = 180°
∠y = 180 - 90° - 32° = 58°
∠y + ∠z + Interior angle of the square = 180° (Sum of angles on a straight line)
58° + ∠z +90° = 180°
∴ ∠z = 32°
∠x = 90°
∠y = 58°
∠z = 32°
Paul and Tammy went out to dinner and the total of their meals was $37.85. Paul spent $12.55 less than what Tammy spent. How much did Paul spend?
Answer:
Paul spent $12.65
Step-by-step explanation:
Create a system of equations where p is how much Paul spent and t is how much Tammy spent.
p + t = 37.85
p = t - 12.55
Solve by substitution:
p + t = 37.85
(t - 12.55) + t = 37.85
2t - 12.55 = 37.85
2t = 50.4
t = 25.2
Find how much Paul spent by plugging in 25.5 as t into p = t - 12.55
p = t - 12.55
p = 25.2 - 12.55
p = 12.65
So, Paul spent $12.65

Copy Mark charges $26 + 44 cents per copy to produce promotional brochures a royal linear equation that relates the cost c in dollars of copies to the number x of copies made and b how many brochures can Steve purchase if he had a budget of $76.16
Answer:
[tex](a)\ y = 26 + 0.44x[/tex]
[tex](b)\ 114\ copies[/tex]
Step-by-step explanation:
Given
[tex]Base\ Charge = \$26[/tex]
[tex]Rate = 44c[/tex] per copy
Solving (a): Linear Equation
The total charges (y) is: the base charge + the rate * number of copies (x).
So, we have:
[tex]y = 26 + 0.44 * x[/tex]
The 0.44 is 44 cents converted to dollars
[tex]y = 26 + 0.44x[/tex]
Solving (b): Purchase if he budgets $76.16
This implies that y = 76.16
So, we have:
[tex]y = 26 + 0.44x[/tex]
[tex]76.16 = 26 + 0.44x[/tex]
Collect like terms
[tex]0.44x = 76.16 - 26[/tex]
[tex]0.44x = 50.16[/tex]
Solve for x
[tex]x = \frac{50.16}{0.44}[/tex]
[tex]x = 114[/tex]
Isabella is bouncing a rubber ball that has a density of 1.5 g/cm3 . The rubber ball has a volume of 113 cm³.
What is the mass of the rubber ball?
Answer:
The mass of the rubber ball is 169.5g
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for m
m=D*V
In this problem we have
V=113 cm^3
D=1.5 g/cm^3
substitute
m.1.5*113=169.5g

Find the equation of the line that goes through the point (4, -3) and has a slope of 0.
Answer:
y = - 3
Step-by-step explanation:
A line with a slope of 0 is horizontal and parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (4, - 3 ) with y- coordinate - 3, then
y = - 3 ← equation of line

Answer:
80
Step-by-step explanation:
x + (2x-60) = 180
combine like terms
3x - 60 =180
add 60 to both sides
3x = 240
divide both sides by 3
x = 80
plug it back in to check
80 + (2(80) - 60 = 180
80 + (160 -60) = 180
80 + (100) = 180
180 = 180
The ordered pairs (20, -29.5),(21, -31), and (22, -32.5) are points on the graph of a linear equation. Which
of the following graphs show all of the ordered pairs in the solution set of this linear equation?
The graph that contains the 3 points is the bottom right graph.
Which line contains the 3 points?We want to see which of the graphs contains the 3 ordered pairs:
(20, -29.5),(21, -31), and (22, -32.5)
So we just need to look at the graphs and see which one has these points, notice that as x increases y decreases, so we have a decreasing line.
The slope of the decreasing line is:
a = (-31 + 29.5)/(21 - 20) = -1.5
The graph with this slope is the last one (bottom right, the other decreasing line has a slope of -1). So that is the correct option.
