Using the combination formula, it is found that Julia can take 15 combinations.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:

For this problem, 4 students are taken from a set of 6, hence the number of combinations is given as follows:

The answer to your question is 7.375
The answer is 4.5, since 1 & 8 are in the middle you add those two numbers and divide by two so 1+8=9 and 9/2=4.5
I think for the question above, instead of 2 · 3^2 · 7 it is <span>2 · 3^2 · 5.

Two numbers have prime factorizations of 2^2 • 3 • 5 and 2 • 3^2 • 5 (note 2 squared & 3 squared).
Now, to choose the GCF, you choose, for each base factor in either number, the least exponent-ed one; so the GCF needs a factor 2, a factor 3, and a factor 5. Thus the GCF is 30 (their product). [i.e,2 squared is not a common factor]
<span>To create the LCM, you choose, for each base factor in either number, the greatest exponented one. Thus, LCM needs a factor 2 squared, 3 squared, and 5, giving LCM = 4(9)(5) = 180.</span><span />
Answer:
If angle B measures 25°, the approximate perimeter of the triangle is 10.48 units. A right triangle is shown. Angle A is 90 degrees and angle B is 25 degrees.
