Answer:

A is the truth

One trick that helps me memorize the placement of the atoms in each state is how the state acts. For example)

Solid, looks tough rigid. A group of Knight made a strong SOLID barrier by grouping together. So you assume that Solid has atoms that are close together

so knight (atoms) together = solid

Liquid, look at how wobbly it is, the knights are running together so their shield is NO LONGER SOLID. You assume that it is liquid cause they are all around, yet they are still together.

so knight (atoms) all around the place together = liquid

Now gases, they are crazy, they go everywhere. The knights are running their own separate way.

So knights (atoms) running everywhere = gases

Hope that answers your question.

Wish the examples were written better tho.

I believe it’s A — atoms in solids are closest together, atoms in liquids are close, but not as compact as in solids, and atoms in gasses aren’t close are all, and they’re constantly moving.

Answer:

We conclude that the proportion of Americans who prefer to drink DD coffee is actually more than what was advertised.

Step-by-step explanation:

We are given that in a recent Dunkin Donuts (DD) commercial, it states that 58% of Americans prefer to drink their coffee.

Of the five hundred randomly selected people who were asked if they preferred DD coffees, 325 said they did.

Let p = proportion of Americans who prefer to drink DD coffee

SO, Null Hypothesis, $H_0$ : p $\leq$ 58% {means that the proportion of Americans who prefer to drink DD coffee is actually less than or equal to what was advertised}

Alternate Hypothesis, $H_A$ : p > 58% {means that the proportion of Americans who prefer to drink DD coffee is actually more than what was advertised}

The test statistics that will be used here is One-sample z proportion statistics;

T.S. = $\frac{\hat p-p}{{\sqrt{\frac{\hat p(1-\hat p)}{n} } } } }$ ~ N(0,1)

where, $\hat p$ = sample proportion of people who prefer to drink DD coffee in a sample of 500 people = $\frac{325}{500}$ = 65% or 0.65

n = sample of people = 500

So, test statistics = $\frac{0.65-0.58}{{\sqrt{\frac{0.65(1-0.65)}{500} } } } }$

= 3.282

Now at 0.05 significance level, the z table gives critical value of 1.6449 for right-tailed test. Since our test statistics is more than the critical value of z so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region.

Therefore, we conclude that the proportion of Americans who prefer to drink DD coffee is actually more than what was advertised.

2/3x+7=5/6 Rewrite the equation below so that it doesn’t have fractions please.

kipiarov [429]

To eliminate all of the fractions in an equation, we can multiply the equation by the least common denominator of all of the fractions in the equation. To find the LCD, we need to find a number that has at least all of the factors of each of the denominators.

To find the LCD of the fractions in this equation, let's look at our denominators, 3 and 6. We can say 3 = 3 and 6 = 2 * 3. By examining this, we can see that our LCD has to have a 3 and 2, since those numbers are found in at least one of the fractions. Thus, our LCD is 3 * 2 = 6.

Now we know to multiply our entire equation by 6. This is solved as shown:

$6(\dfrac{2}{3}x + 7) = 6(\dfrac{5}{6}) \Rightarrow \boxed{4x + 42 = 5}$

Our answer is 4x + 42 = 5.
