A rectangular container can hold 45 candles, while a cylindrical container holds 41 candles. Each rectangular container costs th

Delvig [45]

Answer: Rectangular container is preferred to minimize the costs and there are 142 rectangular container is needed to pack 6400 candles.

Explanation:

Since we have given that

Number of candles in a rectangular container = 45

Number of candles in a cylindrical container = 41

Cost of each rectangular container = $15

Cost of each cylinder container = $16

That means ,

In case of rectangular container,

Cost of 45 candles = $15

Cost of 1 candle is given by

$\frac{15}{45}=\frac{1}{3}=\$0.33$

Similarly,

In case of cylindrical container,

Cost of 41 candles = $16

Cost of 1 candle is given by

$\frac{16}{41}=\$0.39$

So, if the company needs to package 6,400 candles , it should use <u>rectangular containers </u>to minimize costs.

Number of candle he need to pack = 6400

Number of rectangular container for 6400 candles is given by

$\frac{6400}{45}=142.2=142\ approximately.$

Hence, there are 142 rectangular container is needed to pack 6400 candles.

Marina86 [1]

Answer:

Step-by-step explanation:

Hello!

You need to construct a 95% CI for the population mean of the length of engineering conferences.

The variable has a normal distribution.

The information given is:

n= 84

x[bar]= 3.94

δ= 1.28

The formula for the Confidence interval is:

x[bar]± $Z_{1-\alpha/2}$ *(δ/n)

Lower bound(Lb): 3.698

Upper bound(Ub): 4.182

Error bound: (Ub - Lb)/2 = (4.182-3.698)/2 = 0.242

I hope it helps!

A 22.5 ounce candle burns at the rate of one ounce every 5 hours. write an equation for the amount of candle left

maks197457 [2]

Answer:

y = 22.5 - 0.2t

Step-by-step explanation:

Given;

total number of candle, n = 22.5 ounce

Rate of candle burn, R = 1 ounce per 5 hours $= \frac{1 \ ounce}{5 \ hours} = 0.2 \ \frac{ounce}{hour}$

The amount of candle left = total initial value - amount burnt

let the amount let = y

y = 22.5 - 0.2t

where;

t is the time in which the candle is burnt

Thus, the equation for the amount of candle left is given by;

y = 22.5 - 0.2t

The summer camp Jessica attends is four hundred twenty-three and four tenths miles from her home. A detour adds 10 miles to the

juin [17]

Given that Jessica attends summer camp at a distance of four hundred twenty-three and four tenth mile = $423\frac{4}{10} = 423 + \frac{4}{10} = 423+0.4 = 423.4 miles$

And a detour adds 10 miles to the distance.

That means we need to add 10 miles to the given distance.

So new distance = 423.4 + 10 = 433.4 miles

Hence Jessica needs to travel 433.4 miles for summer camp.
