Step-by-step explanation:

First, let's find out how many tiles Mike needs.

Mike's kitchen is 75sqft, each tile covers 2.25sqft, so 75sqft/2.25sqft=33.3333...,

multiply that number by the cost per tile and round to the nearest hundredth.

75 is the total area of the floor, so divide that by how much square feet one tile covers.
75/2.25=33.3
You want to round up to the nearest whole number because you need that extra little 1/3 of tile to cover the whole floor. Make sure you NEVER round down. So now you would need 34 tiles after rounding up.

Next, multiply how many tiles you need by the cost of one tile.
34x1.79=$60.86

What is the Domain of the function indicated by the points on the plane?
kondor19780726 [428]
<h2>Answer:</h2>

A.) {-6, -2, 5}

<h2>Step-by-step explanation:</h2>

A function f from a set A to a set B is a relation that assigns to each element x in the set A exactly one element y in the set B. The set A is the domain (also called the set of inputs) of the function. From the figure, we can see that this set is the x-coordinate of each red point. So this set is {-6, -2, 5}

A spinner is broken into section labeled 1 to 38. What is the probability that.On your next spin, that you will spin a 1?
VashaNatasha [74]

Answer:

1/38

Step-by-step explanation:

Given :

Probability = required outcome / Total possible outcomes

Total possible outcomes = total Numbe rod sections = 38

Required outcome = number of 1's on the entire section = 1

Hence, the probability of spinning a one equals :

P(spinning a 1) = 1 / 38

Suppose you want to decrease your margin of error by a factor of 3. by what factor, do you need to increase your sample size? in
elena55 [62]
The sample size, n required to produce a margin of error, M, in a probability proportion distribution is given by:

n= \frac{p(1-p)z_{\alpha/2}^2}{M^2}

The above formular shows that the sample size is inversely proportional to the Margin of error.

Then we have:

n= \frac{k}{M^2}

where k is some constant.

Now suppose we decrease M by a factor of 3,

\left(i.e.\  \frac{M_1}{M_2} =3\right)

n_1= \frac{k}{M_1^2}  \\  \\ n_2= \frac{k}{M_2^2}  \\  \\  \frac{n_2}{n_1} = \frac{k}{M_2^2} / \frac{k}{M_1^2} = \frac{k}{M_2^2} \times \frac{M_1^2}{k} = \frac{M_1^2}{M^2_2} =\left( \frac{M_1}{M_2} \right)^2=3^2=9 \\  \\ n_2=9n_1

Therefore, if we decrease the Margin of error by a factor of 3, we need to increase the sample size by a factor of 9.
