Answer:

Step-by-step explanation:

In geometry (or math in general), when you do a reflection, rotation, or translation the size or length of the lines don't change. Think about it this way: if I have a log and I bring it into the bathroom with me (don't ask why idk) and hold it up in from of the mirror, what will happen? It will look the same length (and people will think I'm crazy for bringing a log into the restroom with me... but I digress).

Answer:

The answer is "A"

Step-by-step explanation:

A reflection across a line is a rigid transformation. Therefore the shape of the original object will not change. Because of this, you know that it would have the same length as the original line segment.

I hope this helps!!!!

Answer:

340 ways

Step-by-step explanation:

Given:

Total number of oranges = 60

Number of rotten oranges = 4

Number of oranges picked = 3

Now, number of good oranges = Total number - Rotten oranges

= 60 - 4 = 56

Now, we need to pick at least two rotten oranges.

So, the possible outcomes can be as follows:

2 rotten oranges + 1 good orange = 3 oranges
3 rotten oranges + 0 good orange = 3 oranges

Now, number of ways of picking 'r' distinct objects from a total of 'n' objects is given as:

$^nCr=\frac{n!}{r!(n-r)!}$

Now, picking 2 rotten oranges from a total of 4 rotten oranges is:

$^4C_2=\frac{4!}{2!2!}=\frac{4\times 3\times 2}{4}=6$

Similarly, picking 3 rotten oranges from a total of 4 rotten oranges is:

$^4C_3 =\frac{4!}{3!\times1!}=\frac{4\times 3!}{3!}=4$

Now, picking 1 good orange from a total of 56 good oranges is:

$^{56}C_1=56$

Picking 0 good oranges means picking no good oranges.

Therefore, the total number of ways of picking at least 2 rotten oranges is the sum of the above two possibilities and is given as:

At least 2 rotten out of 3 picked = (2 rotten and 1 good) or 3 rotten

= 6 × 56 + 4

= 336 + 4 = 340 ways

Therefore, there are 340 ways of picking at least 2 rotten oranges when 3 oranges are picked from a total of 60 oranges.

Answer:

21 of multiple choice and 17 of short answer questions

Step-by-step explanation:

Multiple choice = m
Short answer = s

Equations:

m + s = 38
2m + 3s = 93

Solve for s by eliminating m. Subtract the double of the first equation from the second one:

2m + 3s - 2(m + s) = 93 - 2(38)
3s - 2s = 93 - 76
s = 17

Find the value of m:

m = 38 - 17 = 21
