Ab + 3c = 2x

Subtract 3c from both sides.

ab = 2x - 3c

Divide a from both sides.

b = 2x - 3c / a

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 $\frac{35}{38}$ .

The expression represents the cost of Janelle’s cell phone bill, where m represents the number of minutes of use. 0.05m + 12 Wha

inn [45]

Answer:

The constant in the expression is 12

Step-by-step explanation:

The constant of the expression is the value that is independent of the number of minutes Janelle uses. The expression can be written as :

f(m)=0.05m +12

Example if m is 1 or 2

f(1) = 0.05(1) +12 = 12.05

f(2= = 0.05*2 +12 =0.1 +12 = 12.1

The value 12 is the minimum price of the bill indepent of the consumption of minutes of Janelle. She will always be charged this value.

What is the missing length? 10.2 cm a area=51 cm2

AleksAgata [21]

Answer:

a = 10 cm

Step-by-step explanation:

Area of triangle, A = 51 cm²

base, b = 10.2 cm

Let height of triangle be a cm

Formula:-

$A=\dfrac{1}{2}\times a\times b$

$51=\dfrac{1}{2}\times a\times 10.2$

$a=\dfrac{51\times 2}{10.2}$

$a=10$

hence, the missing length is 10 cm
