Answer:

$8.40 Total

Step-by-step explanation:

Frozen yogurt costs $0.50 per ounce so the cost for Alec's is 8.6 ounces * $0.50 per ounce which is $4.30. Kiara is 8.2 ounces * $0.50 per ounce which is $4.10. The total is $4.30+$4.10 which is $8.40.

Answer:

$8.40

Step-by-step explanation:

8.6 plus 8.2 is 16.8 so they had a total of 16.8 ounces.  $0.50 per ounce so you need to multiply 16.8 by 0.50 which is 8.40.  you can also do 8.6(0.5) plus 8.2(0.5)=  4.3 plus 4.1 = 8.4

Liula [17]
The goal is to find the area of a pentagon with side length 8.

We can find the area of a pentagon very easily by splitting it up into 10 congruent right triangles with the apothem as the height. The base of one of these triangles would be 4. The base angle would be 54 degrees, because it's half of the angle of a regular pentagon.

Using trig we find that the height of this triangle/apothem of the pentagon is equal to 4tan(54 degrees), which is about 5.506.

The area of a triangle is bh/2, so...4*5.506/2 = 11.011 in².
Times 10 triangles is 110.11 in².

you own a pet supply store, and the total sales in your trading area equal 27,000. Your market share is 45%. What were your sale
Mazyrski [523]

Answer:

The sales is Rs. 12150.

Step-by-step explanation:

Given : You own a pet supply store, and the total sales in your trading area equal 27,000. Your market share is 45%.

To find : What were your sales ?

Solution :

Total sales = 27,000

Market share = 45%

Sales is given by,

Sales is 45% of total sale.

So, S=27000\times \frac{45}{100}

S=12150

Therefore, the sales is Rs. 12150.

For quality control​ purposes, a company that manufactures sim chips for​ cell/smart phones routinely takes samples from its pro
ololo11 [35]

Answer:

There is a 22.42% probability that a sample in this size has 2 imperfections.

Step-by-step explanation:

For each chip, there are only two possible outcomes. Either they are imperfect, or they are not.

This means that we can solve this problem using binomial distribution probability concepts.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}

In which C_{n,x} is the number of different combinatios of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And \pi is the probability of X happening.

In this problem

A success is a chip being imperfect. Suppose the average number of imperfections per 1000 sim chips is 3. So \pi = \frac{3}{1000} = 0.003.

What is the probability that a sample this size​ (1000 chips) has 2​ imperfections?

The sample has 1000 chips, wo n = 1000

We want P(X = 2).

P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}

P(X = 2) = C_{1000,2}.(0.003)^{2}.(0.997)^{998} = 0.2242

There is a 22.42% probability that a sample in this size has 2 imperfections.
