Hello! The answer that you are looking for is D: (-1, -1). Hope this helps!
P.S.
Could you mark me brainliest? It will really help me. Thanks!
Answer:
5/21.
Step-by-step explanation:
Total number of balls = 7.
Prob(Blue on first pick) = 3/7
Prob(Blue on second pick) = 2/6 = 1/3
So Prob( 2 Blue's) = 3/7 * 1/3 = 3/21 = 1/7.
Prob(Red on first pick) = 2/7
Prob(Red on second pick) = 1/6
So Prob( 2 Red's) = 2/7 * 1/6 = 1/21.
Now the Probability of getting 2 white balls is the same as for the red balls
= 1/21.
Finally, the probability of 2 balls of the same colour
= 1/7 + 1/21 + 1/21
= 3/21 + 1/21 + 1/21
= 5/21.
Answer:
3600
Step-by-step explanation:
Each PERSON cost:
Travel cost 130 (assume for whole 7 days since per day is not written)
Hotel 60 per day (so 7 days = 60 * 7 = 420)
Money Spend 350 (assume for whole 7 days since per day is not written)
-------------------------------------------------------------------------------------------------------------
Now, that sums to:
130 + 420 + 350 = £900 [each person for whole 7 days]
Now, there are 4 person, so total cost of whole group (4 persons):
900 * 4 = £ 3600
Solution:
<u>We know the following rules:</u>
- Rule: If an exponent is negative, it will be in the fraction 1/nˣ.
- Rule: If an exponent is positive, it will be in whole number form and will multiply itself m times.
- Rule: if a number's exponent is 0, then the number is 1.
Now, let's solve each problem.
<u>Question-7</u>
- 4³ = 4 x 4 x 4 = 64
- 4² = 4 x 4 = 16
- 4¹ = 4
- 4⁰ = 1
<u>Question-8</u>
- (-2)³ = (-2) x (-2) x -(2) = -8
- (-2)² = (-2) x (-2) = 4
- (-2)¹ = -2
- (-2)⁰ = 1

The width : the length
= 48mm : 105mm
=16 : 35
