Answer:3/20
Step-by-step explanation:
Fraction of total area mowed = (3/5) + (1/4) = 17/20
Therefore fraction of total area left = 1 - (17/20) = (20/20) - (17/20) = 3/20
The probability of it happening once is 1/5, since 10/50 simplifies to 1/5. Because the ticket goes back in the bag, the probability stays constant at 1/5.
For it to happen twice, you multiply the probability of it happening once, twice.
1/5 • 1/5 = 1/25 probability of it being Gary's name twice in a row.
Answer:
D. y = 4x - 6
Step-by-step explanation:
The equation that is perpendicular to the line MN should have a slope that when multiplied by the slope of line MN will result to negative one. Therefore,
Therefore,
m₁ × m₂ = -1
Using the 2 coordinates of MN let's find the slope,
(-7, 6)(5, 3)
Therefore,
m₁ = 3 - 6 / 5 - (-7) = -3 / 12 = - 1 / 4
The equation that represent a line perpendicular to the line MN is
y = 4x - 6 because the slope slope(m₂) is 4.
From our formula,
4 × - 1 / 4 = - 1
So, option D meets the requirement.
Answer:
28BS
Step-by-step explanation:
Compré 30 libros a 40 bs cada uno;
Precio de costo = 30 × 40BS
= 1200 BS
Vendí unos pocos a 360 Bs, a 36 Bs cada uno.
Número de libros vendidos = 360 BS / 36 BS
= 10 libros
Número de libros restantes = 40 BS - 10 BS
= 30 BS
¿Cuánto debo vender cada uno de los libros restantes para no perder ni ganar nada?
Para no ganar ni perder nada, la cantidad total que queda para vender los libros =
1200BS - 360 BS = 840 BS
La cantidad para vender cada uno de los libros restantes sin ganar ni perder nada se calcula como:
840BS / Número de libros restantes
= 840BS / 30BS
= 28BS
