Answer:
B. 252
Step-by-step explanation:
To find the answer, you have to use the formula to calculate the number of combinations as in this case, the order in which the objects are selected doesn't matter:
nCr=n!/r!(n-r)!
n= number of sample points: 10
r= number of sample points in each combination: 5
10C5= 10!/5!(10-5)!
10C5= 10!/5!*5!
10C5= 252
According to this, the answer is that you have 252 different ways to choose your school lunch.

Answer:
A, B, D
Step-by-step explanation:
For appropriate values of 'a', the log function has the following characteristics:
- A: f(1) = 0
- B: f(a) = 1
- D: f(1/a) = -1
Any log function will tend toward negative infinity as x tends to zero (for |a|>1).
Answer:
distance = 50 - (-150) = 50+150 = 200
Therefore, the distance between -150 and 50 is 200 units.
Please check the attached diagram below.
Step-by-step explanation:
Given the numbers
The number 50 is plotted 50 units to the right from position 0 on the number line, which is shown on the number line on the attached diagram below.
The number -150 is plotted 150 units to the left from position 0 on the number line, which is shown on the number line on the attached diagram below.
The distance between 50 and -150 can be calculated by subtracting -150 from 50.
i.e.
distance = 50 - (-150) = 50+150 = 200
Therefore, the distance between -150 and 50 is 200 units.
