Which is the better deal?
aliina [53]

Answer:

36 oz

Step-by-step explanation:

Get the other options down to 12oz units for their price and then you can compare which one is the cheapest for 12oz.

12oz = $1.99

36oz/3 = 12oz   so $2.59/3   = $ .86

48oz/4= 12oz   so $3.99/4  = $1.00

60oz/5= 12oz   so $4.59/5 = $ .92

So looking at the breakdown, the 36oz one is the cheapest because for that price for a third of it comes out to .86 cents.

A salesman who makes $32,500 a year gets promoted to sales manager, earning a new salary of $43,250. What was the rate of increa
OLEGan [10]

Answer:

33.1%

Step-by-step explanation:

First, calculate the dollar amount of the increase.  Subtract $32,500 from $43,250.  We get $10,750.

Next, divide this $10,750 by the original salary, $32,500, to determine what fraction of $32,500 is represented by $10,750:

fraction = $10,750/$32.500 = 0.331

Convert this to a percentage by multiplication by 100%:  33.1%

The rate of increase of the saleperson's salary was 33.1%.

A study was being conducted about birth weights of babies at a local hospital and found the average to be 7.6 pounds with a stan
dangina [55]

Answer:

The birth weight associated with the lowest 1% is 4.6 pounds.

Step-by-step explanation:

Let <em>X</em> represent the birth weights of babies.

It is provided that X\sim N(7.6,1.3^{2})

It is also provided that many pre-mature births weights are in the lowest 1% of births.

Let <em>x</em> represent the births weights that are in the lowest 1% of births.

That is, P (X < x) = 0.01.

⇒ P (Z < z) = 0.01

The corresponding <em>z</em>-score is, <em>z</em> = -2.33.

Compute the value of <em>x</em> as follows:

z=\frac{s-\mu}{\sigma}\\\\-2.33=\frac{x-7.6}{1.3}\\\\x=7.6-(1.3\times 2.33)\\\\x=4.571\\\\x\approx 4.6

Thus, the birth weight associated with the lowest 1% is 4.6 pounds.
