Step-by-step explanation:
<u>Question 18</u>
- Diameter = Difference in y-coordinates
- Diameter = 12 - 2 = 10
- We know : Radius = Diameter/2
- Radius = 10/2
- Radius = 5 cm
- <u>(1) 5 cm</u>
<u></u>
<u>Question 19</u>
- 3x² - 34x - 24 = 0
- (3x + 2)(x - 12) = 0
- Solution set = {-2/3, 12}
- <u>(3) {-2/3, 12}</u>
Answer:
140
Step-by-step explanation:
=(-4+55+18)+(18+25+28)
=69+71
=140
Answer: 16
Step-by-step explanation:
From the question, we are informed that there are 25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple and that one marker is drawn out of the bag, then put back in.
The probability of picking a blue marker will be: = 5/25 = 1/5
Therefore, the number of times that a blue marker will be expected to be picked in 80 draws would be:
= 1/5 × 80
= 16 times
Let n is the number of marbles.
when marbles are equally shared among 6, 7 or 8 students, each time 4 marbles left over.
To find the least number of marbles, first we find out what is the smallest number that can be divided to 6, 7 and 8.
Now you see that 6 and 8 are divisible by 2 but 7 is non- divisible.
if we take LCM of 6, 7 and 8 and find the smallest number.
2 I6,7,8
-------
3,7,4
Now multiply 2,3,7 and 4
2 x 3 x7 x 4 = 168
each time 4 marbles left so
least possible number of marbles in the box = 168 + 4 = 172
