Step-by-step explanation:
y = 6x-11
substitute y into 2x+3y=7
2x+3(6x-11)=7
2x + 18x-33 = 7
20 x = 7+33
x = 2
y?
y= 6(2)-11
y = 12-11 = 1
so, x = 2 and y = 1
Answer:
Step-by-step explanation:
if there are 14 students you can say 5+5=10 so then you have 4 kids remaining which means you can make 2 teams of 5 with 14 students
Answer:
y=-4/5x+2
Step-by-step explanation:
SORRY FOR THE LATE RESPONSE
slope-intercept form is y=mx+b
b is the y-intercept -> 2
m is the slope, which would be the rise/run -> -4/5
to identify the slope all you need to do is pick two points on the line, and find the direction of the line from left to right. rise/run basically means you find the distance going up and down first, and then the distance from left to right next.
now just put the equation together-> y=-4/5x+b
let me know if this helped, or was even right lol
Answer:
3. It is likely.
Step-by-step explanation:
Let's assume the dartboards circles have radius of r, 2r, 3r and 4r from inner side
<u>Then the areas covered will be as:</u>
- point 20 = πr² = S
- point 15 = π(2r)² - πr² = 3πr² = 3S
- point 1 0 = π(3r)² - π(2r)² = 5πr² = 5S
- point 5 = π(4r)² - π(3r)² = 7πr² = 7S
Total area of the dartboard is S+3S+5S+7S = 16S
The area of point 5 is 7S. And the area of non- 5 point is 16S - 7S = 9S
The probability of scoring at least 10 points is:
As it is between 1/2 and 1, the probability is in 'likely' region
<u>So the correct answer choice is:</u> 3. It is likely
