Answer:
B) 36 girls will choose the zoo
Step-by-step explanation:
The data from sample gathered is
Boys Girls
Zoo 15 8
Museum 10 12
Total 25 20
The question asks about what will the data for 90 girls and 78 boys will look like. We can use the data as proportion and make the expected value for the new data. There are 90 girls in the question and the sample is 20 girls, so it's 90/20= 4.5 times larger than the sample. The expected data will be:
Girls
Zoo 8 x 4.5 = 36
Museum 12 x 4.5 = 54
Total 20x 4.5 = 90
The number of boys is 78 while the sample is 25, the data will be
Boys
Zoo 15 x 78/25 = 46.8
Museum 10 x 78/25 = 31.2
Total 25x 78/25 = 78
The answer will be 36 girls will choose the zoo
Answer:
Possible locker numbers for Selma are: 3, 5 and 29
Step-by-step explanation:
First of all, let us have a look at the definition of a prime number.
A <em>prime number</em> is a number which is divisible either by 1 or the number itself.
No other number divides the prime number other than 1 and the number itself.
Now, let us factorize the given number 435 and let us observe the what all possibilities are there.
Factorizing 145 further:
No further factors are possible.
Therefore 3, 5 and 29 are the prime factors of 435.
So, the answer is:
Possible locker numbers for Selma are: 3, 5 and 29

Answer:
−6634
Step-by-step explanation:
((5)(−3))2−((2)(5)−(3)(−3))3
=(−15)2−((2)(5)−(3)(−3))3
=225−((2)(5)−(3)(−3))3
=225−(10−(3)(−3))3
=225−(10−(−9))3
=225−193
=225−6859
=−6634

Answer:
k = -1/2
Step-by-step explanation:
On the right, we can distribute the 2, so we have ...
|2x +1| = |2k -2x|
We can multiply inside the brackets on the right by -1 with no effect:
|2x +1| = |-2k +2x|
Comparing the expressions now, we see they are equivalent when ...
1 = -2k
k = -1/2
___
In the attached graph, the left-side expression is red; the right-side expression is blue dots (when k = -1/2).
