The probability that a plant is edible is 4/5 and the probability that a plant grows at a constant rate and is edible is 14/19.

miskamm [114]

Answer: Probability that a plant grows at a constant rate, given it is edible is given by $\frac{35}{38}$ .

Step-by-step explanation:

Let B be an event that getting a plant grows at a constant rate.

Since we have given that

The probability that a plant is edible is given by

$P(A)=\frac{4}{5}$

The probability that a plant grows at a constant rate and is edible is given by

$P(A\cap B)=\frac{14}{19}$

We will use "Conditional probability ", i.e.

$P(A\mid B)=\frac{P(A\cap B)}{P(A)}$

$P(A\mid B)=\frac{\frac{14}{19}}{\frac{4}{5}}\\\\P(A\mid B)=\frac{14\times 5}{19\times 4}\\\\P(A\mid B)=\frac{70}{76}\\\\P(A\mid B)=\frac{35}{38}$

Hence, Probability that a plant grows at a constant rate, given it is edible is given by $\frac{35}{38}$ .

Solve for x.<br><br> 3/8(2x+16)−2=13

Goryan [66]

3/8(2x+16)-2 = 13
3(2x+16)/8-2 = 13
6x+48/8-2 = 13
6x+48-16/8 = 13
6x+48-16 = 13×8
6x+48-16 = 104
6x = 104+16-48
6x = 120-48
6x = 72
x = 72/6
x = 12

Shelly has a roll of fabric and decides to make some scarves for her friend the roll contains 6 2/3 yards of fabric she needs 5/

ivann1987 [24]

Answer:

Step-by-step explanation:

Total length of the fabric is $6\dfrac{2}{3}=\dfrac{20}{3}\ \text{yards}$

We need to find the number of scarves can she make if she needs 5/6 of a yard for each scarf.

Let she needs x scarves. So, ATQ

$x\times \dfrac{5}{6}=\dfrac{20}{3}\\\\x=\dfrac{20}{3}\cdot\dfrac{6}{5}\\\\x=8$

Hence, she can make 8 scarves.
