3x-5=-15 2x-7=-14 there you go
Answer:
31
Step-by-step explanation:
In order to guarantee that you get 3 colors, you much choose a number that exceeds the number of marbles of the most prevalent 2 colors.
That is, you could choose 30 marbles and only end up with 16 green and 14 blue. To guarantee that you also choose a red, you must choose 31 marbles.
Answer:
Number 1 is 50 and Number 2 is 40
Step-by-step explanation:
25 X 2 = 50
2 X 20 = 40
The question is asking to states the value of the z-score of a value that is 2.08 standard deviations greater than the mean and base on my research, the possible answer would be z-score is the number of standard deviations above the mean. <span>If you are 5 standard deviations above the mean, that is defined as z = 5. </span><span>If you are 1.1 standard deviations above the mean, that is defined as z = 1.1. </span>
<span>And so if you are 2.08 standard deviations above the mean</span>
An apothem of a square is a perpendicular from a center of a square to one of its side.
<span>
</span><span>1. Put a dot at the center of the
square. (You can find the center by drawing diagonals from corner to
corner. The center is where they intersect).</span>
2. <span>Draw a perpendicular line in any of the four directions to one side of the square.</span><span />
3. <span>Two apothems of a square (drawn to opposite sides) make a line that is parallel
to both (left) sides of the square, a line that is of equal length. If two
apothems added together are equal to the length of one side, then one apothem is half of the length.</span>
<span /><span>
</span><span>4. The square perimeter is 40 and it consists of 4 equal parts, then the length of square's side is 10.
</span><span>
</span><span>5. Then the apothem has length 5.
