Could you please rephrase the question? I'm having trouble understanding it.
Answer:
The correct response is: b)
Step-by-step explanation:
a4b=24, where a × 4 × b = 24 implies a × b = 6
The pairs of numbers with a product of 6 include: {1,6} and {2,3}
In base 10, a4b translates to 100a + 40 + b
Calculating gives us:
100×1+40+6=146
100×6+40+1=641
100×2+40+3=243
100×3+40+2=342
Summing these results yields: 146 + 641 + 243 + 342 = 1372
The correct answer is: b)
Answer:
Step-by-step explanation:
Characteristics of a bar graph include:
1). There must be uniform spacing between the bars or columns.
2). Each bar or column should have a consistent width.
3). All bars must share the same baseline.
4). The height of each bar corresponds to the data value.
Based on these criteria,
- Spacing between London-Paris and Rome-Oslo isn’t uniform.
- Width of the Munich bar differs from the others.
For one day:
= £9.20 × 7
= £64.40
For six days:
£64.40 × 6 = £386.40
After sharing with his mom:
£386.40/7 × 5
= £55.20 × 5
= £276
To purchase a car worth £1932:
£1932/£276 = 7
Thus, he needs 7 weeks to save enough for the car priced at £1932.
Answer:
Step-by-step explanation:
Player A has a red marble and a blue marble, while Player B also has a red marble and a blue marble.
Therefore, the probability of selecting one marble is equal, at 0.5.
Due to the independence of A and B's choices, the joint event is calculated by multiplying the probabilities.
Let A represent the amount that player A wins.
If both players select one marble, the sample space can be considered as
(R,R) (R,B) (B,R) (B,B)
Probability 0.25 0.25 0.25 0.25
A's winnings 3 -2 -2 1
E(A) 0.75 -0.5 -0.5 0.25 = 0
Thus, the game is even, offering equal expected values for both A and B.
It does not influence the outcome whether you are A or B.
