Answer:
Yes. It needs to be clear that it is on going. So as long as it is evident that it repeats, you're good.
Step-by-step explanation:
A researcher calculates the expected value for the number of girls in three births. He gets a result of 1.5. He then rounds the result to 2, saying that it is not possible to get 1.5 girls when three babies are born. Is this reasoning correct? Explain.
Answer:
3x - 4y = -10
-4y = -3x - 10
y = (3/4)x + (5/2)
The slope of the perpendicular line will be -4/3.
From (3, -4), go up 4 units, then left 3 units. You will be at (0, 0), so the equation of this line is y = (-4/3)x.
(3/4)x + (5/2) = (-4/3)x
9x + 30 = -16x
25x = -30
x = -6/5, so y = (-4/3)(-6/5) = 24/15 = 8/5
d = √((3 - (-6/5))² + (-4 - (8/5))²)
= √((21/5)² + (-28/5)²)
= (1/5)√(21² + (-28)²)
= (1/5)√(441 + 784)
= (1/5)√1,225
= (1/5)(35)
= 7
The solution to the equation is .
To solve the equation log(x) + log(8) = 2, we can use the properties of logarithms.
The equation can be simplified using the logarithmicproperty:
Rewrite the equation in exponential form:
To solve for x, divide both sides of the equation by 8:
Therefore, the solution to the equation is .
