Answer:

B. The final balance is wrong; she did not add everything correctly.

Step-by-step explanation:

When you spend something fmor an account should go on the debit column and that is the left one, while when you have income or profit that goes on the credit column that is the one in the right, so she has everything on spot, the problem is that she didn´t withdrew correctly the $30 that she paid to the saloon, from the 935.54 that she had in her account to that point, and that eventually messed up her balance.

Answer: B
Look at the line where it says 935 54
Leslie goes to the salon and pays $30
$935.54 - $30 = $905.54

However, the line after the $30 says $900.59, which is incorrect.

Hope this helps!

A waterbed filled with water has the dimensions 8ft by 7 ft by .75 ft taking the density of water to be 1.00/gm cubed how many k
monitta

By definition, the density is given by:

D = \frac{m}{V}

Where,

m: mass

V: volume

Clearing the mass we have:

m = DV

The volume is given by:

V = (8) * (7) * (0.75)

V = 42ft ^ 3

Then, we have the following conversion:

1foot = 0.3048m

Applying the conversion we have:

V = 42 * (0.3048) ^ 3

V = 1.19m ^ 3

On the other hand we have the following conversions:

1m = 100cm

1Kg = 1000g

Applying the conversions for the density we have:

D = (1\frac{g}{cm^3})((\frac{100}{1})^3\frac{cm^3}{1m^3})(\frac{1}{1000}\frac{Kg}{g})=1000\frac{Kg}{m^3}

Then, the mass of the water is:

m = (1000) * (1.19)

m = 1190

Answer:

1190 kilgrams of water are required to fill the waterbed

When a scatter chart of data shows a nonlinear relationship, the nonlinear model can be expressed as:______.
jasenka [17]

Answer:

A

Step-by-step explanation:

The linear model can be assessed by the checking the independent variables having power 1 which shows the linear relationship between x and y. For example, as in the option B, C and D, the power of Xi's is one. Whereas the non linear model has the power for independent variables greater than 1. For example, as in option  A the model is a quadratic model because X associated with β2 has a power of a 2.

Thus the nonlinear model can be expressed as

Y = β0 + β1X + (β2X)2 + ε.

Suppose we have a group of 10 light users and 10 heavy users. what is the probability that exactly 3 of the 20 users are hiv pos
dmitriy555 [2]

Answer: The answer is 30%.


Step-by-step explanation:  Given that there is a group of 10 light users and 10 heavy users. We are to find the probability that exactly 3 of the 20 users are HIV positive.

We have the following four possible cases -

(i) All 3 are light users.

(ii) 1 is a light user and 2 are heavy users.

(iii) 2 are light users and 1 is a heavy user.

(iv) All 3 are heavy user.

Since there is a 45% chance of a light user to be HIV positive and 55% chance of a heavy user to be HIV positive, so the required probability is given by

p\\\\=\dfrac{3\times 0.45+1\times 0.45+2\times 0.55+2\times 0.45+1\times 0.55+3\times 0.55}{20}\\\\=\dfrac{6}{20}\\\\=0.3\\\\=30\%.

Thus, the probability is 30.
