If the scale factor is greater than one, it will always create an enlargement, so since 4/3= 1 1/3 it’s 1 1/3 the size of the original figure, AKA an enlargement
The number of students in 5th grade is 60, since 24% of 250 is 60.
Since 90 is 38% if 250, 38 is going to be the percent of all students in sixth grade.
20% of 250 is 50, so the percent of all students in seventh grade is 50.
Finally, 45 is 18% of 250, so 18 percent of all students are in eight grade.
Hope this helped :)
Cos x = 15÷17
because cos is adjacent side over hypotenuse.
Answer:
The probability that the last card dealt is an ace is
.
Step-by-step explanation:
Given : A deck of ordinary cards is shuffled and 13 cards are dealt.
To find : What is the probability that the last card dealt is an ace?
Solution :
There are total 52 cards.
The total arrangement of cards is 52!.
There is 4 ace cards in total.
Arrangement for containing ace as the 13th card is
.
The probability that the last card dealt is an ace is
![P=\frac{4\times 51!}{52!}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B4%5Ctimes%2051%21%7D%7B52%21%7D)
![P=\frac{4\times 51!}{52\times 51!}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B4%5Ctimes%2051%21%7D%7B52%5Ctimes%2051%21%7D)
![P=\frac{4}{52}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B4%7D%7B52%7D)
![P=\frac{1}{13}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B1%7D%7B13%7D)
Therefore, the probability that the last card dealt is an ace is
.
