Answer:

Total price = $112.70

Step-by-step explanation:

Total price of all three items without tax = 4 + 94 + 6.35

= $104.35

Total price of all three items with tax = (100% + tax) * Price

= (100% + 8%) * 104.35 = 108% * 104.35

= 1.08 * 104.35 = 112.698

≅ $112.70

(2) Explain how to use estimation to check whether your answer is reasonable:

We can use estimation to check if a result is reasonable by plugging in the answer in the original equation.

E.g. x + 4 = 10; x = 10 - 4

We get that x = 6

Plug in x = 6 in x + 4 = 10.

6 + 4 = 10. Indeed the answer was a reasonable one.

Find the length of the side
MrRa [10]

Answer:

So AC = 25

Step-by-step explanation:

ABC = LMN

That means AB = LM

                    BC = MN

                    AC = LN

We know AB = 41  MN = 38  and LN  = 25

AB = LM = 41

BC = MN=38

AC = LN=25

So AC = 25

Answer: 0.9746

Step-by-step explanation:

Given : A normally distributed population has a mean of 250 pounds and a standard deviation of 10 pounds.

i.e. \mu=250 \sigma=10

Sample size : n= 20

Let \overline{x} sample mean values.

Then, the probability that this sample will have a mean value between 245  and 255 be

P(245
