The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
Canadians
Sample size = 50Mean = 4.6Standard deviation = 2.9Americans
Sample size = 60Mean = 5.2Standard deviation = 1.3The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:
[tex]SE = \frac{\sigma}{\sqrt n}[/tex]
The standard error of the Canadian sample is:
[tex]SE_1 = \frac{2.9}{\sqrt{50}}[/tex]
So, we have:
[tex]SE_1 = 0.41[/tex]
The standard error of the American sample is:
[tex]SE_2 = \frac{1.3}{\sqrt{60}}[/tex]
So, we have:
[tex]SE_2 = 0.17[/tex]
The standard error of the difference of sample means is then calculated as:
[tex]SE= \sqrt{SE_1^2 + SE_2^2}[/tex]
This gives
[tex]SE= \sqrt{0.41^2 + 0.17^2}[/tex]
[tex]SE= \sqrt{0.197}[/tex]
Take square roots
[tex]SE= 0.444[/tex]
Hence, the standard error of the difference of sample means is 0.444

How are the nervous systems of a flatworm and a fish different?
A flatworm has a simple nervous system with two nerve cords running down both of its sides. It also has two simple brains, and two eyespots that help sense light. While a fish's nervous system is comprised of a central brain and a spinal cord along with many branching nerves, which allows them to sense things around them.
Explanation:
A flatworm has a very mild nervous system with pair nerve cords moving down each side. It has two single brains called ganglia, which are pure packages of nerves. It has two eyespots that support it sense light. A flatworm has a gastrovascular hole with one opening.
Fish have extremely advanced nervous systems organized around a brain. Fish brains have rare clearly visible parts. Back to the brain is the spinal cord, which is the deep dorsal nerve cord that identifies chordates.

Layla has a coin that has a 60\%60%60, percent chance of showing heads each time it is flipped. She is going to flip the coin 555 times. Let xxx represent the number of heads she gets. What is the probability that she gets more than 333 heads?.
The probability that she gets more than 3 heads is 0.3456.
There are only two possible outcomes for a fliped coin, either it is head, or it is tail. Since the result is independent of each other coins, the binomial distribution will be used.
Given the following parameters:
x is the number of successes = 5 (coin flipped 5 times) n is the number of trials p is the probability of success on a single trial = 0.6Using the binomial distribution formula:
[tex]P(X =x)=nC_x p^x (1-p)^{n-x}\\P(X =3) = 5C_3 \ (0.6)^3 (1-0.6)^{5-3}\\P(X =3) = 5C_3 \ (0.6)^3 (0.4)^{2}\\P(X=3)=0.3456[/tex]

A student combines a solution of nacl(aq) with a solution of agno3(aq), and a precipitate forms. Which of the following is the balanced net ionic equation for the formation of the precipitate?.
Taking into account the definition of net ionic equation, the net ionic equation is Na⁺(aq) + Cl⁻(aq) → AgCl(s) and a precipitate of AgCl is formed when a solution of NaCl(aq) with a solution of AgNO₃(aq) are mixed.
The net ionic equation is a chemical equation for a reaction that lists only the species that participate in the reaction.
In other words, an ionic equation is a chemical equation where electrolytes in aqueous solution are written as dissociated ions. Usually this is a salt dissolved in water, where the ionic species are followed by (aq) in the equation, to indicate that they are in aqueous solution.
The balanced equation will be:
NaCl(aq) + AgNO₃(aq) → AgNO₃(aq) + AgCl(s)
where (aq) means aqueous and (s) solid.
Taking into account that:
All Cl⁻, Br⁻ and I⁻ salts are soluble. Except for the salts that these anions form with Ag⁺, Pb²⁺ and Hg²⁺ cations. All salts of NO₃⁻, C₂H₃O₂⁻, ClO₃⁻ and ClO₄⁻ are soluble.The total ionic equation in separated aqueous solution will be:
Na⁺(aq) + Cl⁻(aq) + Ag⁺(aq) + NO₃⁻(aq) → Ag⁺ + NO₃⁻(aq) + AgCl(s)
A spectator ion is an ion that appears both as a reactant and as a product in an ionic equation.
Spectator ions can be either cations (positively charged ions) or anions (negatively charged ions).
When writing a net ionic equation, spectator ions found in the original equation are ignored. Thus, the total ionic reaction is different from the net chemical reaction.
In this case, Ag⁺ and NO₃⁻ are the spectator ions because they appear unchanged in both the product and the reagent. So these ions cancel out by writing the net ionic equation and you get:
Na⁺(aq) + Cl⁻(aq) → AgCl(s)
Since AgCl is an insoluble salt, it will precipitate.
Finally, the net ionic equation is Na⁺(aq) + Cl⁻(aq) → AgCl(s) and a precipitate of AgCl is formed when a solution of NaCl(aq) with a solution of AgNO₃(aq) are mixed.

A puck is sitting motionless on the ice. Why does it continue to stay in one place.
Answer:
Newton’s first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. It continues to stay in one place because no force is exerted upon the puck, which means that it will continue in a line of rest.

What is Theory of Evolution?Those who are more physically capable of surviving, maturing, and reproducing. On the other hand, those who lack this fitness either do not live long enough to reproduce or have fewer children than their counterparts.
Because the "fittest" organisms—those most adapted to their environment—are the ones that reproduce most successfully and are most likely to pass on their qualities to the next generation, natural selection is sometimes summed up as "survival of the fittest."
This means that if an environment changes, qualities that help people survive in it will eventually adapt, or develop. Natural selection was a potent force.
