165 square feet, approximately.
wlad13 [49]3 years ago

165 square feet is the correct answer. Each half square is equal to 25, so if you add 50 for each full tile and 25 for each half tile, you should reach the answer of 165 square feet.

The length of time a person takes to decide which shoes to purchase is normally distributed with a mean of 8.21 minutes and a st
MaRussiya [10]

Correct answer is: P(x<6) is 0.123 and it is usual.

Solution:-

Given that the time a person takes to decide which shoes to purchase follows normal distribution. Which has mean = 8.21 minutes and standard deviation 1.90

Then probability of individual takes less than 6 minutes is

P(X<6) = P(z

           = P(z

           = 0.1230

Typically we say an event with a probability less than 5% is unusual.

But here P(X<6) = 0.123 is greater than 5% hence this is usual.

Fourth degree and a single zero of -3
Darya [45]

The degree of a polynomial is the highest power of the polynomial.

The polynomial is \mathbf{P(x) = (x + 3)^4}

The degree is given as:

\mathbf{n = 4}

The zero is given as:

\mathbf{x = -3}

Add 3 to both sides

\mathbf{x  + 3= 0}

From the question, we understand that the polynomial has a single zero.

So, the polynomial is:

\mathbf{P(x) = (x + 3)^n}

Substitute 4 for n

\mathbf{P(x) = (x + 3)^4}

Hence, the polynomial is \mathbf{P(x) = (x + 3)^4}

Keelah's clothing store bicycles for $50 and then sells them for $80 what is the percent of markup on the price of the coat
kondaur [170]

Answer:

62.5%

Step-by-step explanation:

We can write a proportion. We know that $50 is the original value and $80 is the marked up price. We don't know the marked up percentage. Let's call it x. We write equal ratios of \frac{x}{100} comparing percent and \frac{50}{80} comparing the 50 to the marked up price. We then set them equal.

\frac{x}{100} =\frac{50}{80}

We then cross multiply across the equal sign from numerator to the opposite numerator.

80(x)=50(100)

80x=5000

We divide to find x.

x=62.5

This means the bicycles are marked up 62.5% and the original value is 37.5%.
