Erik and Kelsey are 240 feet apart when they start walking toward one another. Kelsey walks twice as fast as Erik so whenever Erik travels z feet, Kelsey travels 2x feet. Let z represent the number of feet Erik has traveled since he started
walking toward Kelsey.
a. Write an expression in terms of x to represent the total number of feet Erik and Kelsey have walked toward one
another.
2x+x

b. Write an expression in terms of x to represent the distance (in feet) between Erik and Kelsey.
240/x

c. Let d represent the distance (in feet) between Erik and Kelsey. Write a formula that expresses d in terms of z.
240=d-3x

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
