Answer:
0.6
Step-by-step explanation:
La fórmula para calcular la probabilidad de dos eventos se da como:
P (A⋃B) = P (A) + P (B) - P (A ⋂ B)
De la pregunta, sabemos que:
Probabilidad de que Carlos haya comido pollo frito: P (C) = 0.4.
Probabilidad de que Carlos coma una hamburguesa para el almuerzo: P (H) = 0.3.
Probabilidad de que Carlos almorce pollo frito y hamburguesa el mismo día: P (C ⋂ H) = 0.1.
Probabilidad de que Carlos coma pollo frito o hamburguesa para el almuerzo:
P (C ⋃ H) =?
Por lo tanto, aplicando nuestra fórmula:
P (C ⋃ H) = P (C) + P (H) - P (C ⋂ H)
P (C ⋃ H) = 0.4 + 0.3 - 0.1
P (C ⋃ H) = 0.6
Answer:
yx
Step-by-step explanation:
put 2 variables next to each other and it means multiply.
Answer:
weeks.
Step-by-step explanation:
We have been given that a 
km stretch of road needs repairs. Workers can repair 
kilometer of road per week.
To find the number of weeks it will take to repair the stretch we will divide by
Upon converting our mixed fractions into improper fractions we will get,
Dividing a fraction with another fraction is same as multiplying the 1st fraction with the reciprocal of second fraction.
Therefore, it will take weeks to repair the stretch of the road.
Answer:
y=x-3 (assuming your graph is counting by ones)
Step-by-step explanation:
Slope is 1, I chose two points.
0,-3 and 4,1
Then found the slope with those two points, which was 1.
Then I find the y-intercept, which is where the line and point crosses the y axis, which was -3.
So, I made my equation.
