Answer:
x ≈ - 1.83
Step-by-step explanation:
to solve for x in the question 1.1x + 1.2x - 5.4 = -10
we have
2.3x - 5.4 = -10
collect the like terms
2.3x = -10 + 5.4
2.3x = -4.2
divide both sides by the coefficient of x
2.3x/2.3 = -4.2/2.3
x = -1.826
x ≈ - 1.83
Answer:
slope = - 
Step-by-step explanation:
Parallel lines have equal slopes thus the slope of a parallel line will be equal to the slope of PQ
To calculate slope m use the slope formula
m = 
with (x₁, y₁ ) = P(- 2, 4) and (x₂, y₂ ) = Q(6, - 2)
m =
=
= - 
Answer:
0.3339 = 33.39% probability that both Dave and Mike will show up
Step-by-step explanation:
Probability of independent events:
If A and B are independent events, the probability of both happening at the same time is given by:

In this question:
Event A: Dave shows up.
Event B: Mike shows up.
Christine knows that there is a 47% chance that Dave will not show up and a 37% chance that Mike will not show up.
This means that
.
a. What is the probability that both Dave and Mike will show up

0.3339 = 33.39% probability that both Dave and Mike will show up
She can expect 70 to be ads since there is 10 times more emails so 7 times 10 is 70 so 70 ads
Y2-y1/x2-x1= -47-(-7)/-19-(-9)= 4
