**science**

The sun does not have an atmosphere or crust.

**maths**

Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown. However, the sign is not needed, if a parenthesis is present. 2y(-28)=48 -56y = 48 y = 48/-56 Reduce.

**statistics**

A parameter is data about the whole population, while a statistic deals with a part of the population, a sample. What does that tell you?

**Biology**

It's possible, but what type of genes are going to be inserted? Who will determine who will get what genes? As with medicine, will there be unintended side effects? That should give you a start.

**communicate**

This is asking for your response to an unknown artifact. Our psychic abilities are limited or nonexistent.

Z = (mean1 - mean2)/standard error (SE) of difference between means SEdiff = √(SEmean1^2 + SEmean2^2) SEm = SD/√n If only one SD is provided, you can use just that to determine SEdiff. Find table in the back of your statistics text labeled something like "area...

No information above. Original price of chair missing.

**math (?)**

Data missing. A parameter is a measure on the total population, while a statistic is a measure on a portion of the population.

**statistics**

A normal distribution approximates a bell-shaped curve. Outliers to one side would skew the distribution. If the distribution was flat, having about the same frequencies throughout the distribution, this would be non-normal. Also a bimodal distribution would be non-normal, sug...

I am assuming the Eric is ON the train. 24/3 = 8 ft./sec. 8 + 80 = ?

**Science**

I would assume so. Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.

**algebra 2**

Except for multiplying/dividing by a negative number, treat just like an equation. First get rid of the parentheses by multiplying. 2x - 10 > 6x -18 Subtract 2x from both sides and add 18 to both sides. You should be able to work it from there.

Not sure what this statement means. The light from the sun gets stronger at sunrise and weaker at sunset, but the radiation from the sun is about the same under both conditions.

**Science**

To carry the disease means that it is in the genotype but not the phenotype. That would happen with a recessive gene. It will occur.

**algebra**

Subtract 3x from both sides, then divide both sides by 6.

All correct except 3. Each basket in basketball counts as two points. Also, online “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.

Conclude H1 at the 5% level of significance, since it is a one-tailed test and it is well beyond the 90% confidence limits.

We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.

To get help, you need to post specific questions.

**Statistics**

Proportion = # in category/total number

**Statistics**

When you have specific data, it is descriptive. When you go outside the actual data, it is inferential. 1. a, b and c infer. 2. a describes, b and c infer.
