Answer:

Paula paid for jacket = $82

since price is $8 less than half of original price, we add $8 to the price that Paula paid,

$82 + $8 = 90$

since we have already added $8 to what Paula paid, now to determine the original cost we will just multiply the whole cost  by 2

original price = $90 *$2

= $180

How much does a sleeping bag cost? Let's say you want a sleeping bag that should keep you warm in temperatures from 20°F to 45°F
Ira Lisetskai [31]

Answer:

a) x = 80.40

s = 29.54

b) lower limit = 69.53

upper limit = 91.27

Step-by-step explanation:

The mean price is:

\bar X=\frac{1}{n}\sum x_i=\frac{1}{20}(50+80+...+70)=\frac{1608}{20} =80.40

The standard deviation is

s=\sqrt{\frac{1}{n-1}\sum(x_i-\bar X)^2}=\sqrt{\frac{1}{19}[(50-80.4)^2+...+(70-80.4)^2]} \\\\s=\sqrt{\frac{15,471}{19} }=\sqrt{814.25} =29.54

We have to calculate a 90% CI for the mean.

The z-value for a 90% confidence interval is z=1.645.

The margin of error is:

E=z\cdot \sigma / \sqrt{n}=1.645*29.54/\sqrt{20}=48.59/4.47=10.87

The 90% CI is

\bar X-z\sigma/\sqrt{n} \leq \mu \leq \bar X-z\sigma/\sqrt{n}\\\\80.40-10.87 \leq \mu \leq 80.40+10.87\\\\69.53\leq \mu \leq 91.27

Mr. Meadows has a 6 1⁄2 gallon bucket. His dipping can holds 1 1⁄2 gallons. How many times does he have to dip into the pond wit
Novay_Z [31]

If you were to divide 6 1/2 by 1/12 you would get 4.3 (repeating) but since you cant take .3 of a trip to fill an entire bucket and 4 turns wouldn't fill it completely,

Mr meadows would have to take 5 trips
