A bat and a ball cost one dollar and ten cents in total. The bat costs a dollar more than the ball. How much does the ball cost?

1 answer:

6 0

Set up an algebraic equation: b=cost of ball
1.10=1+b+b
1.10=1+2b
subtract 1 from both sides
.10=2b
divide by 2 on both sides
ball=5 cents

The number of major faults on a randomly chosen 1 km stretch of highway has a Poisson distribution with mean 1.7. The random var

The probability can be modeled using the following formula:
$P(X =3)$
wherein X follows the density
$P(X=k)=\frac{1.7^ke^{-1.7}}{k!}$
Now for k = 3 we get:
$P(X=3)=\frac{1.7^3e^{-1.7}}{3!}=0.15$
The probability we are looking for is 0.15.

In the graph below, line k with equation y = -k makes a 45° angle with the x- and y- axes. Complete the following: Rx Rk : (2,5)

motikmotik

The point with a coordinate of (2,5) will be translated into y=-x line. The transformation for y=-x would be:
1. x'= -y
2. y'= -x

For x=2 and y=5 would be:
x'= -y
x'= -5

y'= -x
y'= -2

The translated coordinate would be: (-5, -2)
