If warming trends continue, which of the following could happen to the glacial ecosystem? Choose ALL that apply.
A
Glacial runoff will begin earlier in the year, and as a result, streams will also warm earlier. Warmer streams will affect native fish populations.
B
Glacial melt and warmer temperatures will increase humidity levels in the ecosystem. This will decrease fish populations that thrive in colder climates.
C
Glacial loss will cool parts of the ecosystem, but because overall temperatures are warmer, precipitation will increase. Increased rain will raise stream and lake levels and increase fish populations.
D
Glaciers will melt into nearby bodies of water. The water levels will rise and create an overall cooling effect on the ecosystem, resulting in a net zero temperature change. The fish population will be unaffected.
E
Glaciers will melt into nearby oceans, causing the salt levels of the ocean to go down. This will increase the available habitat for fish and cause an increase in the nearby population.
If global warming trends continues, the options that could happen to the glacial ecosystem are;
"Glacial melt and warmer temperatures will increase humidity levels in the ecosystem. This will decrease fish populations that thrive in colder climates." (Option B)What is global warming?
Global warming is the name given to the occurrence of the continual melting of the ice cap and the negative effects that this can have on the earth.
Thus, it is right to state that glacial melt will decrease fish populations that thrive in the colder climates.

How many liters each of a 50% acid solution and a 75% acid solution must be used to produce 90 liters of a 60% acid solution? (Round to two decimal places if necessary.)
The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
What is the litters about?Note that:
We take x = volume of 25% solution.
We take y = volume of 65% solution.
So, Equation of total volume:
x + y = 80
Hence the equation of amount of acid:
0.25x + 0.65y = 0.45(80)
0.25x + 0.65y = 36
Solve x + y = 80 for x.
x = 80 - y
Then Substitute into the second equation.
0.25(80 - y) + 0.65y = 36
20 - 0.25y + 0.65y = 36
0.4y = 16
y = 40
x + y = 80
x + 40 = 80
x = 40
Therefore, The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.

Answer:
Answer of #1
5 Cows and 16 Ducks
Explanation:
4x + 2(21-x) = 52
4x + 42 - 2x = 52
2x + 42 = 52
- 42 - 42
2x = 10
x = 5 Number of cows
21 - 5 = 16 ducks.
Checking: The 5 cows have 5 x 4 = 20 legs. The 16 ducks have 16 x 2 = 32 legs.
32 + 20 = 52

A store clerk is paid $10.75/ hour and a store assistant manager is paid $16.25/ hour. How long would it take the store managerto make $500 or more than the store clerk? Round to the nearest hour. Show all work.
It will take approximately 91 hours for the store manager to make $500 or more than the store clerk.
If the store clerk is paid $10.75/ hour and the store assistant manager is paid $16.25/ hour, the difference in their pay per hour will be expressed as:
The difference in the amount earned per hour = 16.25 - 10.75
The difference in the amount earned per hour = $5.5
This means that the store assistant manager will collect $5.5 more than the store clerk in one hour. This can be expressed as:
$5.5 = 1 hour
To determine how long it will take the store manager to make $500 or more than the store clerk, we can write:
$500 = x
Divide both expressions:
[tex]\dfrac{5.5}{500} =\dfrac{1}{x} \\Cross \ multiply\\5.5x = 500 \times 1\\5.5x = 500\\x=\frac{500}{5.5}\\x= 90.9 \ hours[/tex]
This means that it will take approximately 91 hours for the store manager to make $500 or more than the store clerk.

What is probability?Probability deals with the likelihood of an event or phenomena occurring and is quantified as a number between 0 and 1 inclusive, where 0 indicates an impossible chance of occurrence and 1 denotes the certain outcome of an event. Joint probability refers to a statistical measure that determines the probability of two events occurring together and at the same point in time.
Joint probability is the probability of event Y occurring at the same time that event X occurs. Hence, joint probability is a measure of two events happening at the same time and can only be applied to situations where more than one observation can occur at the same time. Mathematically, it is given by P (A and B) = P(A) * P(B) As in the given situation, the probability estimated is the probability to two events that iPhone is defective and it is manufactured by company A occurring at the same time, it is a joint probability.

The length of CE is 3.6 and the radius of the circle is 2
The length of CEStart by calculating the length of AD using:
AD^2 = AC^2 - CD^2
This gives
AD^2 = 10^2 - 6^2
AD^2 = 64
Take the square roots
AD = 8
Represent CE with x.
So:
AE = 10 - x
Calculate ED using:
ED^2 = CD^2 - CE^2
ED^2 = AD^2 - AE^2
So, we have:
AD^2 - AE^2 = CD^2 - CE^2
This gives
8^2 - (10 - x)^2 = 6^2 - x^2
Expand
64 - 100 + 20x - x^2 = 36 - x^2
Add x^2 to both sides
64 - 100 + 20x = 36
Evaluate the like terms
20x = 72
Divide by 20
x = 3.6
Hence, the length of CE is 3.6
The radius of the circleThe equation is given as:
x^2 + y^2 + 6x + 5y = -45/4
Rewrite as:
x^2 + 6x + y^2 + 5y = -45/4
Take the coefficients of x and y
Divide them by 2, square the result and add the result to both sides.
So, we have:
x^2 + 6x + (6/2)^2 + y^2 + 5y + (5/2)^2= -45/4+ (6/2)^2 + (5/2)^2
This gives
x^2 + 6x + (6/2)^2 + y^2 + 5y + (5/2)^2= 4
Express as perfect squares
(x + 3)^2 + (y + 5/2)^2 = 4
The circle equation is represented as:
(x - a)^2 + (y - b)^2 = r^2
Where r represents the radius
By comparison, we have:
r^2 = 4
This gives
r = 2
Hence, the radius of the circle is 2

In a poll, 1002 adults in a certain country were asked whether they favor or oppose the use of "federal tax dollars to fund medical research using stem cells obtained from human embryos." Based on the poll results, it is estimated that 46% of adults are in favor, with a margin of error of 3 percentage points. Use the given statistic and margin of error to identify the range of values (confidence interval) likely to contain the true value of the population parameter
The range of values likely to contain the true value of the population parameter is from 43% to 49%.
What is Population parameter?This is referred to a statistical measurement for a particular population and is usually fixed.
We were told that the margin of error is 3 percentage points. This therefore means:
