Using the coefficient of variation, it is found that the performance of the 5th graders in the district is more variable than that of the norm group in Geography and Science.
What is the coefficient of variation of a distribution?It is given by the division of the standard deviation by it's mean.
Researching this problem on the internet, we have that for geography, the class mean and SD are given, respectively, by 75 and 12, while the norm is of 10 and 85, hence:
[tex]CV_c = \frac{12}{75} = 0.16[/tex]
[tex]CV_n = \frac{10}{85} = 0.12[/tex]
In English, the mean and SD are 100 and 10, respectively, for both, hence:
[tex]CV_c = \frac{10}{100} = 0.11[/tex]
[tex]CV_n = \frac{10}{100} = 0.11[/tex]
In Spelling, they are for the class of 125 and 12, for the norm 15 and 120, hence:
[tex]CV_c = \frac{12}{125} = 0.096[/tex]
[tex]CV_n = \frac{15}{120} = 0.125[/tex]
In Science, they are for the class of 90 and 20, for the norm 15 and 90, hence:
[tex]CV_c = \frac{20}{90} = 0.2222[/tex]
[tex]CV_n = \frac{15}{90} = 0.1667[/tex]
Hence the class is more variable in Geography and Science.

Given the balanced equation representing a reaction: the mole ratio of no to no2 is
Answer:
3:4
Explanation:
In N₂O plus NO mixture (X n2o) equals 1/3. But- the mole fraction of NO in a mixture of NO and NO₂ is (3/4).
Therefore, the mole ratio representing no to no2 is 3:4, representing also the fraction, 3/4, with a numerator of 3 and the denominator of 4.
Here is how I got 3/4, (or to be specific, the RATIO, 3:4.)What is the best analysis of the casual relationship in this scene? this decision will cause caesar to flee from rome.

The ld50 for arsenic in humans is 13mg/kg. Which of the following approaches should be used to calculate the number of grams of arsenic it would take to reach the ld50 in a 140-pound person? [note: 1kg=2. 2pounds]
By performing a change of units, we will see that there are 0.827 g of arsenic needed.
How to calculate the grams of arsenic?
We know that the ld50 for arsenic in humans si 13mg/kg.
Now, if there is a person of 140 lb, to find the number of grams of arsenic it would take to reach the ld50, first we need to rewrite the mass of the person in kilograms.
Remember that:
1kg = 2.2 lb
then:
1 lb = (1/2.2) kg
Then we can rewrite the mass as:
M = 140lb = 140*(1/2.2) kg = 63.64 kg.
The amount of arsenic to reach the ld50 will be:
A = (13mg/kg)*(63.64 kg) = 827.27 mg
And we want this quantity in grams, remember that:
1 mg = 1*10^(-3) g
Then we can rewrite:
A = 827.27*(1*10^(-3)) g = 0.827 g

The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.Researching the problem on the internet, it is found that:
6% of the population is allergic to pollen, hence p = 0.06.Two people are chosen at random, hence n = 2.The probability that both are allergic is P(X = 2), hence:
P(X = 2) = 0.06^2 = 0.0036.
0.0036 = 0.36% probability that both are allergic to pollen.
The probability of at least one is:
P(X >= 1) = 1 - P(X = 0) = 1 - 0.94^2 = 1 - 0.8836 = 0.1164.

Explanation:
they are diffrent cause refraction is solid and diffrection is liquid
Refraction involves the bending of waves through a medium, and diffraction involves the bending of waves around an object. The correct option is 4.
What is refraction?Refraction is the bending of light as it travels through transparent materials. We are able to create lenses, magnifying glasses, prisms, and rainbows because to this bending caused by refraction.
Diffraction and refraction both entail the bending of waves, which makes them comparable. The way this bending happens in them varies, though.
Refraction is the bending of waves as they travel through different media. The wave bends when it passes through various media due to the variations in speed.
Contrarily, diffraction involves the bending of waves as they move through or around an obstruction. As a wave runs into an opening or an object's edges, it stretches out and bends, which causes it to diffract.
Thus, the correct option is 4.
