Answer:
1. and III.
Step-by-step explanation:
Option 1 and 3 are correct.
The probability of landing on heads would be 1/2, so 50 times in 100. This is the expected outcome, so option 1 is correct.
However, that is just the most probable outcome, probability is almost never 100% accurate. Therefore, the number of heads will most likely be 50, give or take 5 or so. Therefore, option 3 is also correct.
Answer:
$285.12
Step-by-step explanation:
first, we'll solve for the 45% sale.
45/100
0.45 x 480
= 216
subtract from the original price
480 - 216
= 264
now we'll solve for the 8%
8/100
0.08 x 264
= 21.12
add the 45% and 8%
264 + 21.12 = 285.12
Answer: It’s the third answer.
Step-by-step explanation:
There are 2.54 cm in one inch and 12 inches in one foot, so 2.54x12 = 1 foot. Multiply this by 2 to get 2 feet.
To divide complex numbers in polar form, divide the r parts and subtract the angle parts. Or
<span><span><span><span>r2</span><span>(<span>cos<span>θ2 </span>+ i</span> sin<span>θ2</span>) / </span></span><span><span>r1</span><span>(<span>cos<span>θ1 </span>+ i</span> sin<span>θ1</span>)</span></span></span></span> <span>= <span><span><span>r2/</span><span>r1</span></span></span><span>(cos(<span><span>θ2</span>−<span>θ1) </span></span>+ i sin(<span><span>θ2</span>−θ1)</span><span>)
</span></span></span>
z1/z2
= 3/7 (cos(π/8-π/9) + i sin(π/8 - π/9))
= 3/7 (cos(π/72) + i sin(π/72))
Answer:
<h3><u>Let's</u><u> </u><u>understand the concept</u><u>:</u><u>-</u></h3>
- Here 12 is 90% of a number.
- So we can say that 90% of That number is 12 .
- In this way we can get the the number
<h3><u>Solution</u><u>:</u><u>-</u></h3>
Let,
the number=x
<h3>According to the question ,</h3>
- We know 90%=90/100
- so add it
- Now use cross multiplication method
- Answer will come in decimals so we take approximate value.
The number is 13.
