Answer:

  2.2, 2.20, 2.2000, 2.20000, ...

Step-by-step explanation:

Any decimal number with more or fewer trailing zeros will be equivalent. Some are ...

  2.2, 2.20, 2.2000, 2.20000

__

These "equivalents" have the same value, but differing numbers of significant digits. If significant digits are important, the given form is the one you want.

[tex]\tt Step-by-step~explanation:[/tex]

Let’s go through several different solutions.

[tex]\tt Simplified:[/tex]

You can just take away two zeros at the end. You will get 2.2.

[tex]\tt Fractions:[/tex]

0.2 is equal to 2/10 or 1/5, so another solution would be 2 1/5.

You can also multiply 5 by 2 and add 1 to get another solution: 11/5.

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:

3/100

0.03

Answer:

So If it is a decimal it is .03 and if it is a fraction 3/100

Step-by-step explanation:

So when it's asking you to find the hundredths you place your decimal point to the left 2 places and when you have a fraction you place the hundred over the number.

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

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%

Answer: 43

Step-by-step explanation:

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.

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:

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
