How are the values of the eights related in 880?

1 answer:

7 0

In the number 880, the first eight is ten times that of the second eight. This is the first way in which the 8’s are related to one another. The second way that the two 8’s are related is that is that if the both 8’s change their respective places, then also the number will remain the same. Since in this case the number in the tens place and the hundreds place are same, so interchanging them will not have any effect on the overall number.

Answer:

0.04

Step-by-step explanation:

In this case we must use the following formula to be able to find the standard error, which would be the square root, of the probability for its complement divided by the population:

SE= $\sqrt{\frac{p *(1-p)}{n} } \\$

Now, knowing that p = 0.552 and n = 160 we replace and we are left with:

SE = $\sqrt{\frac{0.552 *(1-0.552)}{160} } \\$

SE = $\sqrt{0.00154}$

SE = 0.039

Which means that the standard error of the proportion is 0.04

Successive discounts of 20% and 10% are taken on an item priced at $16. Describe how to find the sale price of the item and give

icang [17]

<span>Successive discounts of 20% and 10% are taken on an item priced at $16.
=> Let's find out how much is the discount in all.
=> 16 dollars * .20 = 3.2 dollars
=> 16 - 3.2 = 12.8 dollars.
then another 10% discount,
=> 12.8 * .10 = 1.28 dollars
=> 12.8 - 1.28 = 11.52 dollars is not the price minus the discounts,</span>

Given that a rectangle with length $3x$ inches and width $x + 5$ inches has the property that its area and perimeter have equal

scoray [572]

Answer:

First, we need to know how to calculate the area and the permiter of a rectangle.

To calculate the area, we multiply base by height and to calculate the perimeter, we sum all sides.

Knowing this, we can say that the area is 3x * (x+5) and the perimiter is 3x + 3x + x + 5 + x + 5, as we know both are the same, we write it as an equation:

$3x * (x+5) = 3x + 3x + x + 5 + x + 5$
