Hey the probability of getting head all four time is 2/4
Answer:
12
Step-by-step explanation:
Let x be the number of chocolates in the first jar, then
x ← number of chocolates in second jar and
x + 90 ← number of chocolates in the third jar
The second jar also contains one half the chocolates in the third jar, thus
Equating chocolates in second jar
x = (x + 90) = x + 45
Multiply both sides by 10 to clear the fractions
8x = 5x + 450 ( subtract 5x from both sides )
3x = 450 ( divide both sides by 3 )
x = 150
and × 150 = 120
Number of chocolates in second jar = 120

Áp dụng định lý Pitago trong tam giác vuông:
Tính các cạnh cộng lại sẽ ra chu vi
AB=5
AD=7.211102551
BC=2.828427125
CD=7.280109889
S= AB+BC+CD+AD
What we have been given here are two points.
f(3) = -4 is the same as (3, -4)
f(2) = 6 is the same as (2, 6)
We can then use these two points to find the equation of a line.
Step 1: Find the slope
Slope Formula: (y2 - y1) / (x2 - x1)
Slope = (6 - - 4) / (2 - 3) = (10) / (-1) = -10
Step 2: Find the y-intercept
To find the y-intercept, we'll take our slope and one of our points and plug them into slope-intercept form, then solve for b.
Slope-Intercept Form: y = mx + b
Point = (2, 6)
6 = 2(-10) + b
6 = -20 + b
b = 26
Step 3: Create the equation of the line
Now that we have the slope and y-intercept, all that's left to do is plug both of those values into slope-intercept form.
y = -10x + 26
Answer: y = -10x + 26
Hope this helps!
