Answer: delete “because” I’m assuming that was the underlined portion. If so, the answer choice D would be the correct one.
Answer: 0.99
Explanation:
Chance she will use red roses: 98%
Chance she will use orchids: 87%
Chance she will use Gerber daisies: 94%
probability she has both roses and orchids: 0.82
Probability she has both Gerber daisies and roses: 0.97
What is the probability she has Gerber daisies as she has already chosen red roses =?
Probability of having daisies and choosing red roses= Probability of Daisies and roses/ Probability of red roses)
0.97/0.98 = 0.99
The zebra mussel is an invasive species that decrease the carrying capacity of native species by competing for limited food resources. Invasive species are harmful to the homeostasis of an ecosystem.
The carrying capacity refers to the maximum population size of a species sustained by specific environmental conditions.
The factors that affect the carrying capacity include the availability of both biotic (e.g., food, presence of invasive species, etc) and abiotic (e.g., water, habitat) resources.
For example, Zebra mussels, and Quagga mussels are invasive species that can decrease the carrying capacity of native mussels by taking away limited food and attaching themselves to the native mussels.

The sum of the two numbers is equal to 70.
- Let the first number be x.
- Let the second number be y.
In this exercise, you're required to find two numbers by translating the word problem into an algebraic expression and then solving for the unknown variables (x and y).
Translating the word problem into an algebraic expression, we have;
Two numbers differ by 8:
....equation 1.
The product of the two numbers is 713:
....equation 2.
To calculate the sum of the two numbers:
First of all, we would solve for each of the unknown variables (x and y).
From eqn. 1, we have:
....equation 3.
Substituting eqn. 3 into eqn. 2, we have:
Solving the quadratic equation by factorization, we have:
y = -23 or 31.
For the value of x, when y = 31:
x = 39
Now, we can calculate the sum of the two numbers:
