masya89 [10]

Answer:

96 bars = 10cent each (dime/pence etc) 10.2604166667 each

Step-by-step explanation:

if the cereal bars are accounted for 24inch x 4inch and 4inch lengths seem appropriate length, Then we can account for 1inch x 16 inch widths being 1'' wide each. 6 x 16 = 96 and 96/388 = 4 being the length.

Extended: Area of pan 24 x 16 = 240+148= area of 388in^2

96 bars costing ($9.85) 985/96

Joan conducted a study to see how common binge drinking is on her college campus. She defined "frequent binge drinking" as havin

jenyasd209 [6]

Answer:

z = -1.66

Step-by-step explanation:

Z-statistic:

$z = \frac{X - p}{s}$

In which X is the found proportion.

p is the mean proportion.

$s = \sqrt{\frac{p(1-p)}{n}}$ is the standard error for the data.

Out of 593 students who replied to her survey, 64 fit this criterion.

This means that $X = \frac{64}{593} = 0.108$

She finds that the proportion of binge drinkers nationally is 13.1%.

This means that $p = 0.131$

Also

$s = \sqrt{\frac{0.131*0.869}{593}} = 0.014$

The z statistic for this data is

$z = \frac{X - p}{s}$

$z = \frac{0.108 - 0.131}{0.014}$

$z = -1.66$

Joan is filling a 2-liter soda bottle with different colors of sand to make an art project for her class. She has 1,000 millilit

Marrrta [24]

Answer:

0.4 l of purple sand

Step-by-step explanation:

Volume to be filled in:

2 liter = 2000 ml

Red sand

1000 ml

Blue sand

35 centiliters = 35*10 ml = 350 ml

Yellow sand

2.5 deciliters = 2.5*100 ml = 250 ml

Total volume filled:

1000 + 350 + 250 = 1600 ml

Purple sand needed:

2000 - 1600 = 400 ml = 0.4 l

Answer is 0.4 l of purple sand required

Maggie is considering two investments. Investment A Investment B Principal $10,000 $8,000 Interest rate 3% 2.8% Time in years 5

lana [24]

To solve this we are going to use the simple interest formula: $A=P(a+rt)$
where
$A$ is the final amount.
$P$ is the initial investment.
$r$ is the interest rate in decimal form.
$t$ is the time in years.

Investment A. We know that the initial investment is $10,000, so $P=10000$ . We also know that the number of years is 5, so $t=5$ . To convert the interest rate to decimal form, we are going to divide the rate by 100%
$r= \frac{3}{100} =0.03$
Lets replace those values in our formula to find $A$ :
$A=P(a+rt)$
$A=10000(1+0.03*5)$
$A=11500$

Investment B. $P=8000$ , $t=15$ , and $r= \frac{2.8}{100} =0.028$ .
$A=P(a+rt)$
$A=8000(1+0.028*15)$
$A=11360$

We can conclude that investment A will be worth than investment B at the end of the investment period.
