A company makes bicycles in two sizes. The smaller bicycle weighs 18.5 pounds. The larger bicycle weighs 1 1/4 times as much as the smaller bicycle. How many pounds does the larger bicycle weigh?
Answer:
[tex] \displaystyle23.125 \: \text{pounds}[/tex]
Step-by-step explanation:
we are given that,
the weight of a smaller bicycle is 18.5 poundsthe weight of a larger bicycle is 1¼ times as much as the smaller bicyclein order to figure out the weight of the larger bicycle we can consider using equation
let the weight of the larger bicycle be L
according to the second condition
we acquire
[tex] \displaystyle L = 18.5 \times 1\frac{1}{4} [/tex]
to simplify the mixed fraction to improper fraction we can use the formula given by
[tex] \displaystyle \rm c\frac{a}{b} \xrightarrow{ \text{improper fraction}} \frac{b \times c + a}{b} [/tex]
by using the formula we get
[tex] \displaystyle L = 18.5 \times \frac{5}{4} [/tex]
simplify multiplication:
[tex] \displaystyle L =\frac{92.5}{4} [/tex]
simplify division:
[tex] \displaystyle L =23.125[/tex]
hence,
the larger bicycle weighs 23.125 pounds

Answer: Step-by-step explanation:
If 3 balls are drawn at random from a bag containing 3 red and 4 blue balls,
what is the expected number of red balls in the sample?
Answer:
The expected number of red balls in the sample is 1.2857.
Step-by-step explanation:
The balls are chosen without replacement from the sample, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The expected value of the hypergeometric distribution is:
[tex]E(X) = \frac{nk}{N}[/tex]
3 red balls in the sample:
This means that [tex]k = 3[/tex]
3 balls are drawn:
This means that [tex]n = 3[/tex]
Total of 3 + 4 = 7 balls:
This means that [tex]N = 7[/tex]
What is the expected number of red balls in the sample?
[tex]E(X) = \frac{nk}{N} = \frac{3*3}{7} = 1.2857[/tex]
The expected number of red balls in the sample is 1.2857.

A projectile’s height is given by the equation ℎ=−16^2+280+130, where h represents the height, in feet, t seconds after it was launched.
Part A. How high was the projectile when it was launched?
Part B. How do you know?
Part C. Determine algebraically the maximum height of the projectile.
Part D. The point (13.6, 0) represents a key feature for this projectile. What is its significance in the context of this problem?
Answer: Equation; h = -16x² + 280x + 130
Part A.) It was 130 ft high
Part B.) Substitute 0 in for each x given in the equation, then height, (h) would equal to 130.
Part C) Maximum = (8.75, 1355): it could be found using the formula of -b/2a, to find the x-value of the maximum, and then substituting the x-value in the equation in place of x, to find the y-value
Part D) I tried graphing the point (13.6, 0) in the graph and it doesn't show me anything significant, maybe u can ask this one to from teacher? (sorry bout that)
Hope this helps!
Yesterday, Fairlane got 1 1/2 inches of rain. It got 3/4 of that rain before 3:00 P.M. How much rain did Fairlane get before 3:00 P.M.
Answer:
3/4
Step-by-step explanation:
1 1/2
3/2 make this 6/4 so you can have a common denominator
3/4
Then you subtract and boom 3/4 it also says in the problem lol
Michael surveyed a random sample of students in his school about the number of sports they play. There are 300 students in Michael's school. Use the
results of the survey to estimate the number of students in Michael's school who play exactly one sport.
Answer:
75 students
Step-by-step explanation:
From the table, we can calculate the total number of students surveyed by Michael:
Total student surveyed = 13 + 15 + 32 = 60 students
We can see that out of the 60 students, 15 students played exactly one sport. Hence:
Proportion of students playing exactly one sport = 15 / 60 = 0.25
Based on the result of the survey, if they are 300 students, number of students playing exactly one sport is:
Number of students playing exactly one sport = proportion * total students = 0.25 * 300 students = 75 students

Given the definitions of f(x) and g(x)
below, find the value of f(g(-4)). F(x)=4x+6 g(x)=x^ 2+x-9
Answer:
[tex]f(g(-4)) = 18[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 4x + 6[/tex]
[tex]g(x) = x^2 + x - 9[/tex]
Required
Find f(g(-4))
First, calculate f(g(x))
We have:
[tex]f(x) = 4x + 6[/tex]
[tex]f(g(x)) = 4g(x) + 6[/tex]
Substitute: [tex]g(x) = x^2 + x - 9[/tex]
[tex]f(g(x)) = 4[x^2 + x - 9] + 6[/tex]
Open bracket
[tex]f(g(x)) = 4x^2 + 4x - 36 + 6[/tex]
[tex]f(g(x)) = 4x^2 + 4x-30[/tex]
Substitute [tex]-4[/tex] for [tex]x[/tex]
[tex]f(g(-4)) = 4*(-4)^2 + 4*(-4)-30[/tex]
[tex]f(g(-4)) = 64 -16 -30[/tex]
[tex]f(g(-4)) = 18[/tex]

Rajesh gave 1/2 of his provident fund to his wife,1/4 to his son and the remainder was to be divided equally between his two brothers so that each brother got Rs 10000.
What was the amount of provident fund?
Answer:
$ 80 000
Step-by-step explanation:
provident fund -- x
Wife -- 1/2 of x
Son -- 1/4 of x
Two brothers -- x - (x/2 - x/4)
Therefore, x - (x/2 - x/4) / 2 = 10 000
x = 80 000
Therefore, the amount of provident fund is $ 80 000
