When dragons on planet Pern lay eggs, the eggs are either green or yellow. The biologists have observed over the years that 19%

sineoko [7]

Answer:

Step-by-step explanation:

Since 19% of the eggs are yellow,

then 19% of 63 = 11.97

Since eggs have no fractions, then the mean number of expected yellow eggs is 12.

Answer:

(~1.6,~-8.6)/(1.599,-8.597)

Step-by-step explanation:

This uses the system of equations, if you'd like to find more examples. First, let's mess with the first equation and solve for the easiest findable variable.

1. 3x+8y = -13 -> x = (-13-8y)/3 & y = (-13-3x)/8

2. Using the x equation because it's easier to use when entering into the second equation, we can get 14(-13-8y/3)

(-182-112y)/3 = -10 = 3y/5 is then our new eqn,

Then, we can make the fractions on the right and left equal and find y

9y/15 = -910-560y/15 ->

9y = -910-560y

569y = -910

y = 1.599

3. Now, insert 1.599 into the first x equation we made, x = (-13-8y)/3

to get x = -8.597

4. Your solution is 1.599, -8.597 or ~1.6,~-8.6

Solving Exponential and Logarithmic Equation In exercise,solve for x or t.See example 5 and 6.

Aloiza [94]

Answer:

0.70275

Step-by-step explanation:

Data provided in the question:

4e²ˣ⁻¹ -1 = 5

now solving for 'x'

⇒ 4e²ˣ⁻¹ = 5 + 1

⇒ 4e²ˣ⁻¹ = 6

⇒ $e^{(2x-1)} =\frac{6}{4}$

⇒ $e^{(2x-1)} =\frac{3}{2}$

now,

taking natural log both sides, we get

⇒ 2x - 1 = $\ln(\frac{3}{2})$

also,

we know

⇒ $\log(\frac{A}{B}) = \log(A)+\log(B)$

thus,

⇒ 2x - 1 = ln(3) - ln(2)

⇒ 2x - 1 = 1.0986 - 0.6931

⇒ 2x - 1 = 0.4055

⇒ 2x = 0.4055 + 1

⇒ 2x = 1.4055

⇒ x = 0.70275
