kolezko [41]

Answer:

4 /15

Step-by-step explanation:

From the number cube :

Count of Numbers greater than 4 = 16

Sample space of number cube = 20

P(number greater than 4) = 16 / 20 = 4/5

Word : ATTENTION

Count of letters in attention = 9

Count of T's in attention = 3

P(choosing T) = 3 / 9 = 1/3

P(greater than 4, then T) = 4/5 * 1/3 = 4 /15

Alja [10]

Answer:

y = 0.87x + 0.02

Step-by-step explanation:

Euros as a function of dollars means that euros is y and dollars are x.

We are given 2 points: (4, 3.5) and (10, 8.72)

slope = (8.72 - 3.5)/(10 - 4)

slope = 5.22/6 = 0.87

y = 0.87x + b

3.5 = 0.87(4) + b

b = 0.02

y = 0.87x + 0.02
