Question 13 FUNDRAISER Owen is organizing a fundraiser. The proceeds will be split between a charity and the expenses from the fundraiser. Owen would like the cost of the fundraiser to be 15% of the proceeds. If the fundraiser will cost $500, how much money do they need to raise at the fundraiser?
Answer:
The amount to be raised at the fund raiser is $3,333.33
Step-by-step explanation:
Here, we want to know the amount of money needed to be raised for the fundraiser
Let the amount raised be $x
Thus;
15% of $x = $500
$500 is the cost of the fund raiser
15/100 * x = 500
15x/100 = 500
15x = (100 * 500)
x = (100 * 500)/15
x = 3,333.33

Dan, Eric, and Frank are the leading scorers on their basketball team. Over the course of their high school careers, Dan scored 6/10 of the points that the three boys scored.
If Eric scored 7/10 of the remaining points and Frank scored 120 points, how many points did Dan score?
40 points
280 points
600 points
1,000 points
Answer: 600
Step-by-step explanation:
First, let's define our variables for this problem:
D = # of points that Dan scored.
E = # of points that Eric scored.
F = #of points that Frank scored.
We know that:
"Dan scored 6/10 of the points that the three boys scored."
D = (6/10)*(D + E + F)
"Eric scored 7/10 of the remaining"
In this case, the remaining refers to (1 - (6/10))*(D + E + F) = (4/10)(D + E + F)
Then:
E = (7/10)*(4/10)*(D + E + F)
And we also know that:
F = 120
Then we have a system of 3 equations:
D = (6/10)*(D + E + F)
E = (7/10)*(4/10)*(D + E + F) = (28/100)*(D + E + F)
F = 120
To solve this, the first step is try to reduce the number of variables, then we can just replace the 3rd equation into the other two:
D = (6/10)*(D + E + 120)
E = (28/100)*(D + E + 120)
Now let's try to isolate the variable E in the second equation:
E = (28/100)*D + (28/100)*E + 36.6
E - (28/100)*E = (28/100)*D + 36.6
E( 1 - 28/100) = (28/100)*D + 36.6
E*(72/100) = (28/100)*D + 36.6
E = (100/72)*((28/100)*D + 36.6) = (28/72)*D + 46.666...
Now let's replace this in the other equation:
D = (6/10)*(D + 120 + (28/72)*D + 46.666...)
Let's solve this for D.
D = (6/10)*(D*(100/72) + 166.666) = 100 + D*(47/72)*(6/10)
D - D*(100/72)*(6/10) = 100
D*(1- (100/72)*(6/10) ) = 100
D = 100/((1- (100/72)*(6/10) ) = 600
Dan scored 600 points

-2(x + 3) = -2(x + 1) - 4
A 2
B3
C all real numbers
D no solution
Answer:
Answer is D (no solution)
Step-by-step explanation:
-2(x + 3) = -2(x + 1) - 4 --------multiply what's on the outside with everything on the inside
-2x - 6 = -2x - 2 - 4 -----collect like terms
-2x + 2x = 6 - 2 - 4 --------- add/subtract
0 = 4 - 4
0 = 0
The U.S. Bureau of Labor Statistics released hourly wage figures for various countries for workers in the manufacturing sector. The hourly wage was $30.67 for Switzerland, $20.20 for Japan, and $23.82 for the U.S. Assume that in all three countries, the standard deviation of hourly labor rates is $3.00. Appendix A Statistical Tables a. Suppose 36 manufacturing workers are selected randomly from across Switzerland and asked what their hourly wage is. What is the probability that the sample average will be between $30.00 and $31.00?
Answer:
The probability that the sample average will be between $30.00 and $31.00 is 0.6553.
Step-by-step explanation:
Let X represent the hourly wage for Switzerland.
It is provided that the mean hourly wage for Switzerland was $30.67 and the standard deviation of hourly labor rates is $3.00.
A random sample of 36 manufacturing workers are selected randomly from across Switzerland and asked what their hourly wage.
According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normally.
As n = 36 > 30, Central limit theorem is applicable.
Then, the mean of the sample means is given by,
[tex]\mu_{\bar x}=\mu=30.67[/tex]
And the standard deviation of the sample means is given by,
[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}=\frac{3}{\sqrt{36}}=0.50[/tex]
Compute the probability that the sample average will be between $30.00 and $31.00 as follows:
[tex]P(30<\bar X<31)=P(\frac{30-30.67}{0.50}<\frac{\bar X-\mu_{\bar x}}{\sigma_{\bar x}}<\frac{31-30.67}{0.50})[/tex]
[tex]=P(-1.34<Z<0.66)\\\\=P(Z<0.66)-P(Z<-1.34)\\\\=0.74537-0.09012\\\\=0.65525\\\\\approx 0.6553[/tex]
Thus, the probability that the sample average will be between $30.00 and $31.00 is 0.6553.

The amount of soda in a 16-ounce can is normally distributed with a mean of 16 ounces and a standard deviation of 0.20 ounce. What percentage of these cans will have less than 15.6 ounces
Answer: The percentage of these cans will have less than 15.6 ounces = 2.28%
Step-by-step explanation:
Let x = amount of soda in a 16-ounce can which is normally distributed.
[tex]\mu=16\text{ ounces},\ \ \ \ \sigma=0.20\text{ ounces}[/tex]
The probability that cans will have less than 15.6 ounces:
[tex]P(X<15.6)=P(\dfrac{X-\mu}{\sigma}<\dfrac{15.6-16}{0.20})\\\\=P(z<-2)=1-P(Z<2)\\\\=1-0.9772\ \ \ [\text{By p-value table}]\\\\=0.0228=2.28\%[/tex]
Hence, the percentage of these cans will have less than 15.6 ounces = 2.28%

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The
profit on every sandwich is $2, and the profit on every wrap is $3. Sal made a profit
of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents
Sal's profits last month, where x is the number of sandwich lunch specials sold and
y is the number of wrap lunch specials sold. describe how you would graph this line using the slope-intercept method. be sure to write using complete sentences
Answer:
y=-3/2x+745
Step-by-step explanation:
so u you convert standard form to slope intercept which would be y=-3/2x+745 the y intercept is 745 and the slope (rise over run is the -3/2).
Answer:
1. slope intercept form is y=mx+b, where m is the slope and b is y-intercept. To write this in slope intercept form we must isolate the y.
2x+3y=1470
2x+3y-2x=1470-2x( subtraction will cancel the positive 2x on the left side)
3y=-2x+1470 ( since they are not like terms we can not combine them, we leave them separate)
3y/3=-2/3x+1470/3( cancel the 3 by dividing, EVERYTHING IN THE EQUATION gets divided to keep it equal)
So, y=2/3x+490 in other words the slope of the equation is -2/3 and the y-intercept is 490.
2. To graph this equation plot 490 on the y-axis first, seeing it is the y-intercept. Then count over to the right 3 and down 2, to find your next point and do this for every other point.
.3. In function notation this would look like this : f(x)=-2/3x+490. This function shows how the profit on wrap specials has changed as the number of sandwich specials sold increases
5. The next month Sals profit increased. The function changes because the y-intercept changes. The slope will stay the same.
