Answer:

x = 7 units

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

   5 cm                 3 cm

------------------ = ------------------------

(40 + 5) cm      (3 + 2x + 10) cm

This simplifies to:

  5             3

-------- = -----------

  45       2x + 13

Solve for x.  Cross-multiplying, we get:

10x + 65 = 135, or x = 7

So x = 7 units.

Mice and Pain Can you tell if a mouse is in pain by looking at its facial expression? A new study believes you can. The study1 c
kotykmax [81]

<u>Explanation:</u>

1. a) Null hypothesis: There is <em>no</em> statistically significant relationship between the mouse grimace scale and the amount of pain felt by mouse.

b) Alternate hypothesis: There is a statistically-significant relationship between the mouse grimace scale and the amount of pain felt by mouse.

2. Yes, because a statistically significant data implies that there is sufficient evidence to believe the study, based on the results of the findings.

3. No, since the variables are different in this case. Here we are dealing with a non-painful solution so there may be no sample correlation as extreme as that found in the original study.

4. Possibly, because every hypothesis is an assumption until it is proven. Thus, in every statistical research, there may be different findings.

Which of the following represents the graph of f(x) = one−half to the power of x?
puteri [66]

f(x) = \frac{1}{2}^x

In this exponential function , the base is \frac{1}{2}

if base is less than 1 then it a decreasing function

We can verify it using a table

We plug in some x and values and find out f(x) to get point for the graph

x -----> f(x)

-1 -----> 2

0 ------> 1

1 -------> 0.5

The table is same as the points in first graph.

So first graph represents the graph of f(x) = \frac{1}{2}^x
