Answer:

x=15√2

Step-by-step explanation:

15²+15²=c²

225+225=c²

450=c²

√450=c

√9x25x2=c

√9x√25x√2=c

3x5x√2=c

15√2=c

(Or you could use the 45-45-90 rule for triangles to get the same thing).

Answer:

x = 9

Step-by-step explanation:

I think you wrote the question wrong (I am assuming that there is a x next to the -3).

Subtract 7

-27 = -3x

divide by -3

A student solves a problem correctly 40 times out of 72 tries. Based on this data, what is the probability that the student inco

suter [353]

Answer:

The probability of the student incorrectly solves the next problem is 44%.

Step-by-step explanation:

Let E be the event of solving a problem correctly.

Then E' is the event that the problem is solved incorrectly.

Now, recall the definition of probability.

probability of an event = $\frac{number of favorable events}{total number of events}$

So,

p(E) = $\frac{40}{72}$

Also,

p(E) + p(E') = 1 and

p(E') = 1 - p(E)

= 1 - $\frac{40}{72}$

= $\frac{72-40}{72}$

= $\frac{32}{72}$

= $\frac{4}{9}$

= $\frac{4}{9} (100)$

= 44% rounded.

Hence, the probability of the student incorrectly solves the next problem is 44%.

Figure 2 was constructed using figure 1. For the transformation to be defined as a rotation, which statements must be true? Sele

Thepotemich [5.8K]

Answer:

The segment connecting the center of rotation, C, to a point on the pre-image (figure 1) is equal in length to the segment that connects the center of rotation to its corresponding point on the image (figure 2).

The transformation is rigid.

Every point on figure 1 moves through the same angle of rotation about the center of rotation, C, to create figure 2.

If figure 1 is located 360° about point C, it will be mapped onto itself.
