A small train at an amusement park is carrying passengers. Half of the passengers are 6 years old, 1 over 10 are 7 years old, 1 fifth are 8 years old, and 1 fifth are 9 years old.
What is the expected age for one of the passengers on the train?
6 years
7.1 years
8 years
8.5 years
The expected age for one of the passengers on the train is 7.1 years. This can be explained by following steps:
Following are the calculation for the expected age given
½ = 6 years old
1/10 = 7 years old
1/5 = 8 years old
1/5 = 9 years old
With the help of the above information, expected age can be calculated as follows:
Expected age = ½*6+1/10*7+1/5*8+1/5*9
= 6/2+7/10+8/5+9/5
=3+0.7+1.6+1.8
= 7.1
Therefore, the correct answer is 7.1 years old.

Evaluate the function rule for the given value. f(x) = 3x for x = –5
Final answer:
To evaluate the function f(x) = 3x for x = –5, substitute in the value to get f(–5) = –15. For the second part, none of the options perfectly match the description, but y = x² is closer as it is a quadratic function.
Explanation:
To evaluate the given function rule f(x) = 3x for x = –5, you simply substitute –5 in for x in the function. Here is the calculation:
f(–5) = 3 * (–5) = –15
Now, regarding the second part of the question, at x = 3, the function f(x) has a positive value with a positive slope that is decreasing in magnitude with increasing x. The function y = x² fits this description because it is a quadratic function where the slope (the derivative) is 2x. At x = 3, the slope is positive (2 * 3 = 6), and as x increases, the slope increases, but the rate of increase in slope (the second derivative) is constant, not decreasing. Hence, neither option a nor b perfectly fits the condition of a positive slope that is decreasing in magnitude with increasing x. However, option b, y = x², is closer to the description compared to the linear option a, y = 13x, which has a constant slope.
In two or more complete sentences, explain whether the sequence is finite or infinite. Describe the pattern in the sequence if it exists, and if possible find the sixth term. 2a, 2a2b, 2a3b2, 2a4b3. . .
Answer:
a). it is an Infinite Sequence.
b). This sequence is Geometric Progression.
c). [tex]6th\,term\,of\,this\,GP\,=\,2a^6b^5[/tex]
Step-by-step explanation:
Given: A Sequence 2a , 2a²b , 2a³b² , [tex]2a^4b^3[/tex]
To find: a). Given Sequence is finite or infinite
b). Pattern of the sequence
c). Sixth term
a). Since, there is no detail about no. of terms of the sequence.
Therefore, It implies it is an Infinite Sequence.
b). Given 1st term = 2a , 2nd term = 2a²b , 3rd term = 2a³b²
First we find the difference of 1st and 2nd term
d = 2a²b - 2a ⇒ d = 2a (ab - 1)
Now, Difference of 2nd and 3rd term,
d = 2a³b² - 2a²b = 2a²b (ab - 1)
So, This Sequence is not a Arthematic Progression.
Now, we find the ratio of 2nd term to 1st term,
[tex]r\:=\:\frac{2a^2b}{2a}\,=\,ab[/tex]
Ratio of 3rd term to 2nd term,
[tex]r\:=\:\frac{2a^3b^2}{2a^2b}\,=\,ab[/tex]
Since, the ratio is common.
This sequence is Geometric Progression.
So, Pattern is next term of this sequence has 1 more in power of a and b
⇒ [tex]nth\,term\,of\,this\,GP\,=\,2a^{n}b^{n-1}[/tex]
c). [tex]6th\,term\,of\,this\,GP\,=\,2a^{6}b^{6-1}[/tex]
[tex]6th\,term\,of\,this\,GP\,=\,2a^6b^5[/tex]
Therfore, a). it is an Infinite Sequence.
b). This sequence is Geometric Progression.
c). [tex]6th\,term\,of\,this\,GP\,=\,2a^6b^5[/tex]

The perimeter of a rectangle is 36 yards. The width is 18 yards less than twice the length. Find the length and the width of the rectangle
The length of the rectangle is 12 yards and the width is 6 yards. The problem is solved with algebra using the formulas for the perimeter of a rectangle and given relation between the length and width.
Explanation:This problem involves the use of algebra in solving geometrical problems. The question provides information about the perimeter and the relationship of length to width using algebraic expressions. To find the length and the width, we can use the formulas for the perimeter of a rectangle (P=2L + 2W) and the given width (W=2L-18).
Let L represent the length. Then, 2L+W=18 represents the width. Setting 2L + 2W equal to the given perimeter of 36, we get 2L + 2(2L - 18) = 36.
Solving this equation gives: L = 12, and substituting L=12 into W=2L - 18, we get: W=6. Hence, the length is 12 yards and the width is 6 yards.

identify an equation in point-slope form for the line parallel to y=1/2x-7 that passes through (-3,-2)
To find an equation in point-slope form for a line parallel to y=1/2x-7 that passes through (-3,-2), we can use the fact that parallel lines have the same slope. The equation of the parallel line is y = (1/2)x + 5/2.
Explanation:To find an equation in point-slope form for a line parallel to y = (1/2)x - 7 that passes through the point (-3, -2), we need to use the fact that parallel lines have the same slope.
The given line has a slope of 1/2, so the parallel line will also have a slope of 1/2.
Using the point-slope form y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope, we substitute the values to get the equation y - (-2) = (1/2)(x - (-3)). Simplifying this equation gives us the final answer: y = (1/2)x + 5/2.

A machine cuts a strip of carpet into two pieces. The length of the smaller piece is 5 meters greater than the length of the larger piece. If the length of the smaller piece is 12 meters, the length of the bigger piece is meters and the total length of the carpet is meters.
Answer:
The length of the bigger piece is 17 meters
and the total length of the carpet is 29 meters.
Step-by-step explanation:
The length of the smaller piece is 5 meters greater than the length of the larger piece.
i.e. Length of larger piece=Length of smaller piece+5
The length of the smaller piece is 12 meters.
So, Length of larger piece=12+5
=17 meters
Total Length of carpet=Length of smaller piece + Length of larger piece
= 12+17
= 29 meters
Hence, the length of the bigger piece is 17 meters
and the total length of the carpet is 29 meters.
