**Math**

Find the mean (∑x/n) for your sample and multiply by 150.

**Psychology (statistics)**

Don't know about Q 25, but I would use the median and quartiles.

I don't understand your notation. However, to answer your question, convert the raw scores to standard scores, like the Z score. Z = (score-mean)/SD Which Z score, if any, is higher?

**Psychology**

If you cannot put the symbols in clearly, spell out the names for the concepts.

**PSY (?)**

Same problem.

**PSY (?)**

Population mean = 100 and the standard deviation (SD) = 16, and N = 64? Do you know where the = sign is? Even so, we do not have data on the sample.

Tutors are online at different times. You may have to wait for a response to the problems you post.

**science**

We need to have the specific problems along with your answers before anyone can check them you.

**Spanish**

My Spanish is rusty, but you don't want an infinitive. If in the future, Yo te presentaré a mis amigos. If in the present, Yo te presento a mis amigos. Except for a command, the direct object pronoun comes before the verb. Don't you want the third person plural ...

**add maths (?)**

We need an "equals" (=) designation somewhere to get an equation.

**algebra**

It would help if you proofread your questions before you posted them. I assume the top equation is -4x+3y = 3. Multiply that equation by 3. I assume the second equation is 7x + 9y = 6. -12x + 9y = 9 7x - 9y = 6 Add the two equations. -5x = 15 Take it from there.

**MATH**

m = .4h 15m + 7h = $45.50 Substitute .4h for m in second equation and solve for h. Insert that value into the first equation and solve for m. Check by inserting both values into the second equation.

What is I.T.? Don't use acronyms unless you are sure that your audience knows their meaning. What is being processed?

**Anatomy & Physiology**

Don't agree. Check with your text or Google each term.

**Statistics**

If by "out of control" you mean deviant, I would agree. Baseline is not the same as average. It is the cutting point at which you will reject the product. It would depend on the quality standards you have for your product. An an analogy, let's use academic grades...

**Math**

As far as I know, unless you can transform the figure into a series of right triangles, you can't.

**statistics**

I don't know what you mean by a "running number." If you want a measure of central tendency for a relatively normal distribution, calculate the mean. It functions as a fulcrum (balance point) for the distribution.

**Genetics**
