Let x be the number of seventh grade students.
The 20% of the seventh grade students have math class in the morning means mathematically is 20/100.
The 16 2/23% of those students also have science class in the morning means:
16 2/3 & 20/100 = also have class in the morning
83 1/3 * 20/100 = math in the morning but not in science in the morning
30 students have math in the morning but not science in the morning
83 1/3% * 20/100% * x = 30
250/3 * 20/100x = 30
x = 180
There are 180 seventh graders.
Answer:
The x-intercept is (-2,0)
The y-intercept is (0,3)
Step-by-step explanation:
An x-intercept is the point when the graph crosses the x-axis. In other words, the y-coordinate of the x-intercept is 0 (since it lays on the x-axis). In other words, to solve for the x-intercept(s), plug in 0 for y and solve for x:

So, the x-intercept is (-2,0).
Likewise, the y-intercept is the point when the graph crosses the y-axis. Because it's on the y-axis, the x-coordinate value would be 0. Thus, to find the y-intercept, plug in 0 for x and solve for y:

Thus, the y-intercept is (0,3).
Answer:
<h2>The answer is 0.1493.</h2>
Step-by-step explanation:
In a standard deck there are 52 cards in total and there are 4 aces.
Two cards can be drawn from the 52 cards in
ways.
There are (52 - 4) = 48 cards rather than the aces.
From these 48 cards 2 cards can be drawn in
ways.
The probability of choosing 2 cards without aces is
.
The probability of getting at least one of the cards will be an ace is
.
Answer: A: 
Step-by-step explanation:
The square root of 3 is an irrational number. It is also known as Theodorus' constant, after Theodorus of Cyrene, who proved its irrationality.
You would have to divide 37.2 by 10. The answer would be 3.72.
