Answer:

Step-by-step explanation:

the probability is 1/48 because

to get a number 6 is a 1/8 percent chance.

the get the letter C is a 1/6 percent chance

you multiply 1/6 and 1/8 to get the probability of 1/48

Answer:

1/48

Step-by-step explanation:

For the left spinner, there are 8 equal slots and one of which is 6. The probabililty of landing on just six would be 1/8.

For the right spinner, there are 6 equal slots and one of which is C. The probability of landing on just C would be 1/6.

Now when we try to get to spin both of them at the same time we need to multiply the probabilities of both:

1/8*1/6=1/48

Hope this helps!

When pricing out a menu, we know it is important to use the Edible a portion Price. What would the effect on your profit margin

Colt1911 [192]

The effect of Edible a portion Price on your profit margin , if we only use the as purchased price to determine our cost and selling price is that it will maximize the profit because it will account for every part of the production.

<h3>What is edible portion cost?</h3>

The portion cost can be calculated by multiplying the cost of a usable kg with the portion size.

This can be represented as : portion cost = (portion size x cost of usable kg)

It should be noted that Edible portion (EP) serves as the portion of food which will be given top the customer after the preparation.

The amount that households pay service providers for access to the Internet varies quite a bit, but the mean monthly fee is $50

Natali5045456 [20]

Answer:

(a) See Explanation

(b) $\bar x =50$ and $\sigma_x = 0.8944$

(d) $P(\bar x > 55) = 0$

Step-by-step explanation:

Given

$\mu = \$50$ -- mean

$\sigma = \$20$ --- standard deviation

$n=500$ --- sample size

Solving (a): The reason we can't determine the probability that an amount to access internet by a household will exceed $55.

The question says that a lot of households pay low rates, but the percentage of the households in this category is not given. This means that it is impossible to determine the shape of the distribution.

Hence, the probability cannot be calculated.

Solving (b): Sample mean and Sample standard deviation

The sample mean estimates the population mean

So:

$\bar x =\mu$
