Answer:

Step-by-step explanation:

We are given an equation , so we first need to simplify the equation

lets distribute the x on parenthesis first

$2x^2 -x- 15 = x^2 + x.$

Now bring all terms to the left so we get

$2x^2-x-15-x^2-x=x^2+x-x^2-x$

$x^2-2x-15=0$

Now since all terms are in one side , so we now factor the equation

$(x-5)(x+3)=0$

Now apply the zero product property to get

x-5=0 or x+3=0

x=5 or x=-3

solution x=-3 or x=5

Ksju [112]

If you know the base and area of the triangle, you can divide the base by 2, then divide that by the area to find the height. To find the height of an equilateral triangle, use the Pythagorean Theorem, a^2 + b^2 = c^2.

The Bureau of Labor Statistics1 in the US tells us that, in 2010, the unemployment rate for high school graduates with no colleg

mars1129 [50]

Answer:

$p_1 -p_2 = 0.097-0.052 = 0.045$

So then the difference between the two proportions is 0.045 and if we convert this into % we got

$0.045*100= 4.5%$

Step-by-step explanation:

For this case we can define the following notation:

$p_1$ represent the unemployment rate for high school graduates with no college degree

$p_2$ represent the unemployment rate for college graduates with a bachelor's degree

And for this case we need to find the difference in proportions of those unemployed between these two groups, we want to find:

$p_1 -p_2$

From the info given we have $p_1 = \frac{9.7}{100}=0.097$

$p_2 = \frac{5.2}{100}=0.052$

And the difference:

$p_1 -p_2 = 0.097-0.052 = 0.045$

So then the difference between the two proportions is 0.045 and if we convert this into % we got

$0.045*100= 4.5%$

Leviafan [203]

Answer:

3.428571429 or approximately 3.43

Step-by-step explanation:

3/2

= 1.5

7/8

= 0.875

1.5/0.875

= 1.714285714

1.714285714/0.5

= 3.428571429

or approximately 3.43
