The probability that exactly 1 doesn't grow will be 0.07
<h3> What is Probability?</h3>
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We can use Bernoulli estimation to solve this. P(g) = 0.85, probability of not growing into healthy plant P(n) = 1-P(g) = 1 - 0.85 = 0.15
Using the Bernoulli approximation:
P(n=1)=⁹C₁xP(n)¹.⁵xP(g)⁸.⁵
P(n=1)=9x0.15¹.⁵x0.8⁸.⁵
P(n=1)=0.07
Hence the probability that exactly 1 doesn't grow will be 0.07

#SPJ1
4/15 = 50/x...4 ft to 15 min = 50 ft to x minutes
this is a proportion, so we cross multiply
(4)(x) = (15)(50)
4x = 750
x = 750/4
x = 187.5 minutes or 3 hrs and 7.5 minutes
or u can do it this way..
15/4 = 3.75 ft per minute......50 * 3.75 = 187.5 minutes
Answer:
Step-by-step explanation:
we will remove the parenthesis
2.75x+0.25x+1-x+3.8=
=2 x+4.8
choice A
A cube is a 3d object bounded by 6 square faces.
Each side of the display case is 3 times longer than the width of the artifact.
width of the artifact = w
side of the cube = 3w
<span>a. Write an expression for the volume of the case.
volume of a cube is the measure of its side raised to the power of 3.
Volume = (3w)</span>³
<span>Volume = 27w</span>³<span>
