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

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.

Answer:

120

Step-by-step explanation:

Answer:

A = - 0.3 and B = - 0.1.

Step-by-step explanation:

y(x) = A sinx + B cosx

y'(x) = A cosx - B sinx

y"(x) = -A sinx - B cos x

So, substituting we have:

y" + y' - 2y = -A sinx - B cos x + A cosx - B sinx - 2(A  sinx + B cosx)

=    -3A sin x - B sinx + A cosx  - 3B cos x = sinx

sin x (-3A - B) + cos x(A - 3B) = sin x

Since this is an identity then we equate coefficients:

-3A - B =  1

A - 3B = 0

Solving these we get A = - 0.3 and B = - 0.1.

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%

-320 is the answer to your mathematical problem

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

Answer:

15

Step-by-step explanation:

mode is the most occurring

first let's put our data in order

2, 5, 6, 8, 10, 11, 15, 15, 16, 17, 20, 25

each number occurs once except 15

15 occurs twice which means it's the most occurring or mode

x = 28

Step-by-step explanation:

If y = 252, solve for x

y = 9x

252 = 9x

x = 28

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
