Answer:
Captain Marvel
Step-by-step explanation:
Answer:
6x^2 + 8x + 28
Step-by-step explanation:
2 times the length plus 2 times the width gives the perimeter
2(3x^2 + 3x + 6) + 2(x + 8)
6x^2 + 6x + 12 + 2x + 16
6x^2 + 8x + 28
Whatever the exponent is on ten is the amount of spaces the decimal moves.
8. 91.2
9. 6200
10. 6250
11. 8240
12. 304.32
13. 51.234
<span> Percents as decimals are that number divided by 100. The rule is to move the decimal 2 places to the left.
.9
.3
1.159
.09
.07
.65
.003
4.45
edit:
None need to be rounded so do you mean given to the thousandth place? In that case the thousandth is 3 decimal slots places to the left so like this:
.900
.300
1.159
.090
.070
.650
.003
4.450</span>
Answer:
There are 220 ways by which the medals can be awarded to three of the 15 gymnast, if exactly one of the Americans wins a medal
Step-by-step explanation:
From the question, we have;
The number of gymnast in the Olympic women's competition = 15
The number of the gymnast who are Americans = 4
The number of medals awarded = 3 medals
The number of ways hat the medals can be awarded to the three of the gymnast if exactly one of the Americans wins a medal is given as follows;
The number of ways one of the medals can be won by one of the four Americans = ₄C₁ = 4 ways
The number of ways the other two medals can be won by the remaining 11 gymnast = ₁₁C₂ = 55 ways
Therefore, the total number of ways, 'N', the medals can be awarded to three of the 15 gymnast, if exactly one of the Americans wins a medal is given as follows;
N = ₄C₁ × ₁₁C₂
∴ N = 4 × 55 = 220
