A survey found that the American family generates an average of 17.2 pounds of glass garbage trash each year. Assume the standar
SIZIF [17.4K]

Answer: 0.8137

Step-by-step explanation:

As per given , we have

\mu= 17.2\ ,\ \sigma=2.5

Sample size : n= 47

Let \overline{X} be the sample mean o.

Then, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds will be :

P(16.6

=P(-1.645

[∵ z= \dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]

=P(z

=0.8636793-(1- 0.9500151)  [By using p-value calculator]

=0.8636793-0.0499849=0.8136944\approx0.8137

Hence, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds= 0.8137

Geometry help please explain no graph
katrin2010 [14]

Answer:

d. 24

Step-by-step explanation:

m∠10 ≅ m∠12 cause they're alternate exterior angles and im taking geometry rn:)

m∠10 = 3x - 2

m∠12 = 70

3x - 2 = 70

3x = 72

x = 24

What are the solutions to the following system of equations? x + y = 3 y = x2 − 9 (3, 0) and (1, 2) (−3, 0) and (1, 2) (3, 0) an
OLga [1]

The solutions for the given system of equations are:

(3, 0), (-4, 7).

<h3>How to solve the given system of equations:</h3>

Here we have the system:

x + y = 3

y = x² - 9

To solve this, we can replace the second equation into the first one, so we get:

x + (x² - 9) = 3

Now we can solve this quadratic equation for x, we need to solve:

x² + x - 12 = 0.

The solutions are given by Bhaskara's formula:

x = \frac{-1 \pm \sqrt{1^2 - 4*1*(-12)} }{2*1} \\\\x = \frac{-1 \pm 7 }{2}

Then the two solutions are:

x = (-1 + 7)/2 = 3

x = (-1 - 7)/2 = -4

To get the y-values correspondent, we can evaluate the linear equation in these two values:

y = 3 - x.

For x = 3:

y = 3 - 3 = 0

For x = -4:

y = 3 + 4 = 7

Then the two solutions are: (3, 0), (-4, 7).
