A soccer team played 160 games and won 65 percent of them. How many games did it win ? Please show work
Answers
Hope this helps! :D Feel free to ask more questions, or ask me questions about my explanation.
The number of games won is 104.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of games = 160
Percentage of games won = 65%
Now,
The number of games won.
= 65% of 160
= 65/100 x 160
= 104
Thus,
The number of games won is 104.

During one day on the stock market, an investor lost $2500 on one stock, but gained $1700 on another. At the end of trading that day, the investor's holdings were worth $52500. What were they worth when the market closed that day?
Answers
Before trading day:
The holdings were worth x + y.
At the end of the trading day:
Holding x changes to x - 2500 because of loss.
Holding y changes to y + 1700 because of gain.
The holdings are worth $52500 at the end of trading, therefore
(x - 2500) + (y + 1700) = 52500
x + y - 800 = 52500
x + y = 53300
Answer:
Before the trading day, the holdings were worth $53,300.
At the end of the trading day, the holdings were worth $52,500.
45/100 in simplest form
Answers
First, let's take a look at our numbers.
45 / 100
Both of these numbers have a 0 and a 5, which means it is divisible by 5.
Let's divide both of them by 5.
45 / 5 = 9
100 / 5 = 20
We are now left with 9/20.
This is your simplified fraction since 9 and 20 do not have any common factors.

Every day, the number of network blackouts has a distribution (probability mass function)
x | 0 | 1 | 2
P(x)| 0.7| 0.2| 0.1
A small internet trading company estimates that each network blackout results in a $500
loss. Compute expectation and variance of this company’s daily loss due to blackouts.
I computed this E(x)= .4 , varX= .44, but I don't know how i can find the answer?
The answer is
E(Y ) = 200 dollars,
Var(Y ) = 110, 000 squared dollars.
Answers
The expected daily loss of the company due to blackouts, E(Y), can be calculated by multiplying each possible loss (which is the number of blackouts times 500) by the probability of that loss occurring, and summing these products. The variance, Var(Y), is found by first finding the expected value of the square of the loss, E(Y^2), which is done in a similar way to finding E(Y), but by squaring each loss before multiplying by its probability. The variance is then given by E(Y^2) - [E(Y)]^2, resulting in a variance of $110,000.
Explanation:The expectation (or mean) of a random variable Y can be computed by multiplying each outcome by its probability and summing all these products. The random variable Y here is the daily loss corresponding to x blackouts, which is given by 500*x, where x is the number of blackouts. Hence to find the expected daily loss, E(Y), you need to calculate:
E(Y) = 0*0.7 + 1*500*0.2 + 2*500*0.1 = $200
The variance of a random variable is found by taking the expected value of the squared variation of that variable from its mean. In this case, you'll calculate:
Var(Y) = E(Y^2) - [E(Y)]^2.
To find E(Y^2), you'll calculate:
E(Y^2) = 0*0.7 + (1*500)^2*0.2 + (2*500)^2*0.1
Substitute E(Y) and E(Y^2) into the variance formulas to get Var(Y) = 110,000.
So, the expectation and variance of the company's daily loss due to blackouts are $200 and $110,000 respectively.

If the directrix of a parabola is the horizontal line y = 3, what is true of the parabola?
a)The focus is at (0, 3), and the equation for the parabola is y2 = 12x.
b)The focus is at (0, –3), and the equation for the parabola is x2 = –12y.
c)The focus is at (3, 0), and the equation for the parabola is x2 = 12y.
d)The focus is at (–3, 0), and the equation for the parabola is y2 = –12x.
Answers
Explanation:
This equation may be written in standard form as
[tex]y=- \frac{1}{12} x^{2} [/tex]
The coefficient in front of x² is negative so the curve is downward.
The vertex has coordinates (0,0).
The vertex is equidistant from the directrix and the focus, so the focus is (0, -3).

Estimate the circumference of the circle to the nearest hundredth. Use 3.14 the diameter is 11
Answers
[tex]c= \pi D[/tex]
Now, plug in pi as 3.14 and D as 11:
[tex]3.14 * 11 = 34.54[/tex]
Your answer is 34.54.
The circumference of a circle with a diameter of 11 using 3.14 for pi is estimated to be 34.54 to the nearest hundredth.
Explanation:To estimate the circumference of a circle to the nearest hundredth, we use the formula C = πd, where C is the circumference and d is the diameter of the circle. Given that the diameter is 11 and we should use 3.14 for π, the calculation is C = 3.14 × 11. Performing the multiplication gives us a result of 34.54, which is the estimated circumference of the circle to the nearest hundredth.

To satisfy his grandmother's request, Dave needs to mix [tex]\( \frac{1}{5} \)[/tex] cup of fruit for every [tex]\( \frac{1}{3} \)[/tex] cup of nuts.
To find out how many cups of fruit Dave needs to mix for a single cup of nuts, we need to find a common denominator for [tex]\( \frac{1}{5} \)[/tex] and [tex]\( \frac{1}{3} \)[/tex], which is 15.
[tex]\[ \frac{1}{5} \times \frac{3}{3} = \frac{3}{15} \][/tex]

If f(x) = 3x + 10x and g(x) = 2x – 4, find (f – g)(x).
Answers
Final answer:
To find (f - g)(x), subtract the function g(x) from f(x) by expanding and combining like terms.
Explanation:
To find (f - g)(x), we need to subtract the function g(x) from f(x). The given functions are f(x) = 3x + 10x and g(x) = 2x - 4. Let's subtract g(x) from f(x):
(f - g)(x) = (3x + 10x) - (2x - 4)
Expanding the expression, we get:
(f - g)(x) = 3x + 10x - 2x + 4
Combining like terms, we simplify it to:
(f - g)(x) = 11x + 4
