Answer:
25%
Step-by-step explanation:
It has a 50% chance of being in D and A is half the size of D so 50/2=25%
Answer:
The inequality the graph has shown is y < 2x - 3 ⇒ C
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
- m is the slope of the line
From the given figure
∵ The line drawn is a dashed line
→ That means the sign of inequality without the equal sign
∴ The sign of the inequality is without the equal sign
∵ The shaded area is under the line
→ That means the sign of the inequality is smaller than
∴ The sign of the inequality is <
∵ The line intersects the y-axis at point (0, -3)
→ That means the y-intercept is -3
∴ The y-intercept = -3 ⇒ (value of b in the equation of the line)
∵ There is only one answer has sigh < and y-intercept -3
∴ The inequality the graph has shown is y < 2x - 3
Answer:
3
Step-by-step explanation:
Answer:
Log [x^2 / yz^2]
Step-by-step explanation:
2log(x) =log(x^2)
-log(y) = The minus sign means that you can divide it by first log(x^2)
-2log(z) =log(z^2), and the minus sign again means you can divide it by the first log(x^2)
So, the whole thing can be written like this:
Log(x^2) / [log(y)*log(z^2)], OR:
Log [x^2 / yz^2]
Answer:
x = ± 
, x = ± i
Step-by-step explanation:
f(x) = 
- x² - 2
to find the zeros , equate f(x) to zero , that is
- x² - 2 = 0
using the substitution u = x² , then
u² - u - 2 = 0 ← in standard form
(u - 2)(u + 1) = 0 ← in factored form
equate each factor to zero and solve for u
u - 2 = 0 ⇒ u = 2
u + 1 = 0 ⇒ u = - 1
convert u back into terms of x
x² = 2 ( take square root of both sides )
x = ±
x² = - 1 ( take square root of both sides )
x = ± 
= ± i
