Answer:

x = 6

Step-by-step explanation:

In similar triangles,  corresponding sides are in same ratio

\frac{x+3}{3}= \frac{6}{2}\\\\ \frac{x+3}{3}=3\\\\x+3 = 3*3\\\\x+3 = 9\\\\x = 9-3\\\\x = 6

Slope of (-2,-3) and (6,2)
alexira [117]
\frac{5}{8} is the slope between these two points. 

To figure out the slope between two points, we need to find the rise over run, which is the change in the <em>y value over the change in the x value</em>. This becomes:

\frac{2 - (-3)}{6 - (-2)}

And simplifies to:
\frac{5}{8}, meaning that the slope between these two points is \frac{5}{8}.

If the critical z-value for a hypothesis test... If the critical z-value for a hypothesis test equals 2.45, what value of the te
schepotkina [342]

Answer: z score = 0.00714

Step-by-step explanation: the value of test statistics is gotten using the standard normal distribution table.

Z= 2.45 has area to the left (z<2.45) and area to the right (z>2.45).

Level of significance α is the probability of committing a type 1 error. The area under the distribution is known as the rejection region and it is the area towards the right of the distribution.

The table I'm using is towards the left of the distribution.

But z>2.45 + z<2.45 = 1

z> 2.45 = 1 - z<2.45

But z < 2.45 = 0.99286

z > 2.45 = 1 - 0.99286

z >2.45 = 0.00714

Hence the test statistics that would produce the least type 1 error is 0.00714

Someone please help me to find the answer to this geography problem please explain
Kisachek [45]
First, we must know what the two variables in the equation y=mx+b really means.

The M represents slope while the B represents the Y-intercept.

With that out of the way, take a look at your top equation, y = 3/2x + ?. If you noticed the question mark is in the spot of the B (Y-intercept), we can simply find this by finding where on the graph does the line intercept the Y-axis.

Triangle B shows the Y-intercept to be -7, this means that the hypotenuse intercepts the Y-axis at (0 , -7).

If we were to find the (what I like to call) the interception point of triangle A's hypotenuse and the Y-axis, we find our missing variable.

Just looking at the graph, we can count and visually determine that the Y-intercept of the hypotenuse is (0 , 1).

Therefore, we can say: The equation of A's hypotenuse is:
y = 3/2x + 1

Hope I could help you out!
