Alexxandr [17]

Answer:

Step-by-step explanation:

x + y = 6 and xy =2

Left sides multiplied= right sides multiplied

Multiply (x+y) by xy = 6*2

(x+y) xy = 6*2

Distribute

x^2y + xy^2 = 12

Two urns both contain green balls and red balls. Urn I contains 6 green balls and 4 red balls and Urn II contains 8 green balls

34kurt

Presumably, whatever is drawn from Urn I is independent of what is drawn from Urn II. This means

$P(\text{red from Urn 1 AND red from Urn 2})=P(\text{red from Urn 1})\cdot P(\text{red from Urn 2})$

We have

$P(\text{red from Urn 1})=\dfrac4{10}=\dfrac25$

$P(\text{red from Urn 1})=\dfrac7{15}$

so the probability of drawing red balls from both urns is $\dfrac25\cdot\dfrac7{15}=\dfrac{14}{75}$

Answer:

$9d = 36$

Step-by-step explanation:

See attachment for complete question

$Length = 36ft$

$n = 10$

From the question, we understand that one shrub must be at both ends.

Taking the first as a point of reference, we're left with:

$(n - 1) * distance = 36$

Substitute 10 for n and d for distance

$(10 - 1) * d = 36$

$9 * d = 36$

$9d = 36$

Hence:

$9d = 36$ answers the question
