Answer:

x = - 27/8

$x=-3\frac{3}{8}$

Step-by-step explanation:

¹²⁾x/5 - ¹²⁾1/5 = ²⁰⁾x/3 + ¹⁵⁾1/4

12x - 12 = 20x + 15

- 12 - 15 = 20x - 12x

- 27 = 8x

x = - 27/8

$x=-3\frac{3}{8}$

In one region, the september energy consumption levels for single-family homes are found to be normally distributed with a mean

Mrac [35]

We first calculate the z-score corresponding to x = 1075 kWh. Given the mean of 1050 kWh, SD of 218 kWh, and sample size of n = 50, the formula for z is:
z = (x - mean) / (SD/sqrt(n)) = (1075 - 1050) / (218/sqrt(50)) = 0.81
From a z-table, the probability that z > 0.81 is 0.2090. Therefore, the probability that the mean of the 50 households is > 1075 kWh is 0.2090.

The total cost is $43.5 and it is obtained from the equation c = 6.5n + 25

<u>Solution:</u>

Given that, while your family is visiting Deep creek lake, you and your mother decide to go boating.

The Rangers charge $6.50 per hour in addition to $25.00 deposit to rent a canoe.

If you wish to rent the canoe from 12:30 to 3:30 PM,

We have to write and solve a linear equation to find the total cost to rent the canoe.

Now, we know that,

<em>total cost = charges + rent fee </em>

$\text {Total cost }=\text { number of hours used } \times \$ 6.5 \text { per hour }+\$ 25$

Let total cost be "c" and number of hours rented be "n"

$\begin{array}{l}{c=n \times 6.50+25} \\\\ {c=6.5 n+25 \rightarrow(1)}\end{array}$

Now, they used canoe from 12:30 to 3:30, which means 3 hours of time

So, put n = 3 in (1)

c = 6.5(3) + 25

c = 19.5 + 25

c = 43.5

Hence, the total cost is $43.5 and it is obtained from the equation c = 6.5n + 25

Use the quadratic formula to solve the equation 2x^2+2x-4=0

const2013 [10]

Answer:

Step-by-step explanation:

The quadratic formula for the quadratic equation ax² + bx + c = 0:

$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

$2x^2+2x-4=0\qquad\text{divide both sides by 2}\\\\x^2+x-2=0$

$a=1,\ b=1,\ c=-2$

Substitute:

$x=\dfrac{-1\pm\sqrt{1^2-4(1)(-2)}}{2(1)}=\dfrac{-1\pm\sqrt{9}}{2}=\dfrac{-1\pm3}{2}\\\\x_1=\dfrac{-1-3}{2}=\dfrac{-4}{2}=-2\\\\x_2=\dfrac{-1+3}{2}=\dfrac{2}{2}=1$
