Answer:
9 teenagers
Step-by-step explanation:
12/20 = x/15
180/20 = x
9 = x
-----------------------
9 teenagers would take to finish the large pizza in 15 mins
Total number of marbles:
75 + 50 + 100 + 25 =
250
Probability of selecting a red marble:
25/250 (since 25 out of 250 marbles are red)
Since the top and bottom of this fraction are both divisible by 25, we can go ahead and divide them both by 25, simplifying to
1/10.
Probability of selecting a green marble:
50/250
Simplifies to 2/10
Simplifies to
1/5.
Probability of selecting a blue or orange marble
(75+100)/250
175/250
Simplifies to
7/10.
To find the probability that each event occurs in order, simply multiply them all together.
2x-1 < x+3
5x-1 > 6-2x
x-5 < 0
solve the inequality for x.
x < 4
x > 1
X < 5
find the intersection
X ∑ {1,4}
Alternative form: {x I 1 < x < 4}
∑ indicates summation and is used as a shorthand notation for the sum of terms that follow a pattern. For example, the sum of the first 4 squared integers, 12+22+32+42, follows a simple pattern: each term is of the form i2, and we add up values from i=1 to i=4.
Answer:
the percentage of men over 50 who wear watches are 61.82%
Step-by-no step explanation:
first just multiply 275 the number of people over 5o then divide it by .6 to get 165 is the answer
i hope this is correct
