Step-by-step explanation:

If the vector CD is a multiple of the vector BC

(CD = kBC, where k is a real constant

and k =/= 0),

Then BCD is a straight line.

Vector BC = Vector BA - Vector CA

= (5a - 2b) - (3a + b) = (2a - 3b).

Vector CD = Vector CA + Vector AD

= (3a + b) + (3a - 10b) = (6a - 9b)

Since 3(2a - 3b) = (6a - 9b), => k = 3,

The points B, C and D are collinear.

Hence we conclude BCD is a straight line.

B) y = -2x

when x = a

y = -2a

when x= 2a

y = -2(2a) = -4a

Joni earned $0.625 per day for two days as interest on her $1,000.00 investment. What percent interest did she earn in total? Gi

Kitty [74]

Joni’s total interest earned is 0.125% of her investment.

<u>Solution:</u>

Given that

Interest earned by Joni per day = $0.625

Investment done by Joni = $1000

Duration of earning interest = 2 days

Total interest earned = interest earned by Joni $\times$ duration of interest earned.

= 0.625 $\times$ 2 = $1.25

$\text { Percentage of interest earned }=\frac{\text {total interest earned}}{\text {investment done}} \times 100$

$=\frac{125}{1000} \times 100=0.125 \%$

So Joni’s total interest earned is 0.125% of her investment.

Si yo tengo una canasta llena de mangos y piñas, de las cuales hay 30

skelet666 [1.2K]

Respuesta: Es más probable sacar un mango.

Explicación:

La probabilidad se refiere a la posibilidad de que un evento occura y no otro. En el caso que se describe, la probabilidad de sacar cada fruta puede ser calculada dividiendo el total de cada fruta en el número de frutas totales:

Probabilidad de sacar un mango:

$\frac{cantidad de mangos}{cantidad de frutas en la canasta}$ = $\frac{30}{50}$ = $0.6$

Probabilidad de sacar una piña:

$\frac{cantidad de pinas}{cantidad de frutas en la canasta} = \frac{20}{50}$ $= 0.4$

De acuerdo a lo anterior la probabilidad de sacar un mango es de 0.6 o de 60% (multiplica la probabilidad por 100 para saber su equivalente en porcentaje), mientras que la probabilidad de sacar un mango es de 0.4 o 40% lo cual es mucho más bajo. Es decir que es más probable sacar un mango.
