Answer:
-0.3
Step-by-step explanation:
9 ÷ 3[(18 − 6) − 22]
= 9 ÷ 3[(12) − 22]
= 9 ÷ 3[-10]
= 9 ÷ (-30)
= -0.3
Answer:
Step-by-step explanation:
Given the data:
Individual Method 1 Method 2 1 7 5 2 5 9 3 6 8 4 7 7 5 5 6
The point estimate for the difference between the means is the difference between the mean of method one and the mean of method 2
Roots at x=-10 and x=-8
if a function has roots at x=r1 and x=r2, then the factored form is
f(x)=a(x-r1)(x-r2) where a is a constant
so
roots -10 and -8
f(x)=a(x-(-10))(x-(-8))
f(x)=a(x+10)(x+8)
now
use (-9,-3)
-3=a(-9+10)(-9+8)
-3=a(1)(-1)
-3=-a
3=a
the equation is
y=3(x+10)(x+8)
or expanded
y=3x²+54x+240
Answer: You need more information to solve this.
Step-by-step explanation:
a= how many cards you have overall
B= how many blue cards there are
C= how many blue cards you have after you took one out
D= how many cards you have overall after you took one out
B/a*C/D= your answer

----------------------------------------------
y = 2x + 3 - it's a linear function. We only need two points to plot the graph. Select two any x values and calculate the y values:
for x = 0 → y = 2(0) + 3 = 0 + 3 = 3 → (0, 3)
for x = -2 → y = 2(-2) + 3 = -4 + 3 = -1 → (-2, -1)
y > 2x + 3
Dot line an shading above the line (look at the picture).
