Because ACT is so specific about the types of questions it expects you to answer, you can easily prepare to tackle them.

Not all standardized tests allow calculators. Fortunately, ACT does. Your calculator can help to save a ton of time on operations that are easy to mess up like multiplying decimals or working with big numbers.

The place where you have to be really careful with your calculator, though, is on the easy ones. Be careful with negative numbers! You are permitted to use a calculator for these questions. You may use your calculator for any problems you choose, but some of the problems may best be done without using a calculator.

Answer: C This might look like a traditional plug-and-chug problem, but the problem is asking for a specific value, and the answer choices are all real numbers. A great indication that you can plug in the answer. The problem is asking for the largest, so start with choice E. Eliminate choice E. If you selected choice Abe careful; this is the smallest value of x that solves the equation.

Answer: G If you have one piece of information about a circle, you can find everything else you need. If the radius of circle B is half that of circle Athen the radius of circle B must be 2. In the word HAWKS, how many ways is it possible to rearrange the letters if none repeat and the letter W must go last?

Answer: C This is problem is asking for arrangements, so start by creating the number of slots you will need: 1 2 3 4 5. Your first impulse here may be to solve for the unknown side, but take a close look at where the marked angle is. Its adjacent side is 5, meaning the tangent of that angle must have a denominator of 5. Only D has it, so it's the only answer that can work. If you do solve for the unknown side, remember your Pythagorean triples: this is a triangle, so the unknown side must be Our private tutors will help you build a prep plan that's customized to your score goals, study habits, and schedule.

I'd like to thank Fred J. I've tried to proof read these pages and catch as many typos as I could, however it just isn't possible to catch all of them when you are also the person who wrote the material. Fred, Mike and David have caught quite a few typos that I'd missed and been nice enough to send them my way.

Thanks again Fred, Mike and David! If you are one of my current students and are here looking for homework assignments I've got a set of links that will get you to the right pages listed here. I've made most of the pages on this site available for download as well. These downloadable versions are in pdf format.

Each subject on this site is available as a complete download and in the case of very large documents I've also split them up into smaller portions that mostly correspond to each of the individual topics.

To get the downloadable version of any topic navigate to that topic and then under the Download menu you will be presented an option to download the topic. Here is a complete listing of all the subjects that are currently available on this site as well as brief descriptions of each. In particular it is assumed that the exponents and factoring sections will be more of a review for you.

Also, it is assumed that you've seen the basics of graphing equations. Graphing particular types of equations is covered extensively in the notes, however, it is assumed that you understand the basic coordinate system and how to plot points. There is some review of a couple of Algebra and Trig topics, but for the most part it is assumed that you do have a decent background in Algebra and Trig.

These notes assume no prior knowledge of Calculus. It is also assumed that you have a fairly good knowledge of Trig. Several topics rely heavily on trig and knowledge of trig functions. It also assumes that the reader has a good knowledge of several Calculus II topics including some integration techniques, parametric equations, vectors, and knowledge of three dimensional space.

These notes assume no prior knowledge of differential equations. A good grasp of Calculus is required however. This includes a working knowledge of differentiation and integration.Comparing Numbers. Daily Math Review. Division Basic.

Ryan Goldberg Deadspin Jun 2016 40min Permalink. By Peter Hayter Updated: 00:47 GMT, 14 September 2010 A senior betting industry expert and adviser to world cricket's Anti-Corruption Unit last night urged them to add the first ball wide from Pakistan fast bowler Mohammed Aamer to the three no-balls under investigation from the tarnished Lord's Test.

Mark Davies was one of the founders of Betfair, the world's largest internet betting exchange, and has advised the Unit on all aspects of the sport's links with the gaming industry. He believes the International Cricket Council inquiry into allegations of bowling no-balls to order - against suspended Pakistan trio Mohammad Aamer, Mohammad Asif and Test captain Salman Butt - should also focus on the opening delivery of the match by Amir, a wide that cost five runs.

The ICC inquiry is running parallel to Scotland Yard's criminal investigation which has led to Aamer, Asif and Butt being interviewed under caution, with a fourth tourist, Wahib Riaz due for interview on Thursday. The delivery in question was bowled by the left-arm paceman Aamer, 18, over the wicket from the Pavilion End to England captain Andrew Strauss.

It landed a foot outside leg stump and carried on, with the angle, passing the stumps by at least a yard on its way to the boundary. Wicketkeeper Kamran Akmal, along with Butt currently under ICC investigation over possible spot-fixing at the Asia Cup and the World Twenty20, made no attempt to reach the ball as it sailed to the fine leg boundary.

Umpire Billy Bowden signalled four wides which, with the one-run penalty for the wide itself, added up to five runs from the first ball of the match.Susin, Canada Iceland Complete, July 2014 We wanted to travel around the Ring Road in Iceland for two weeks on our own (parents and one teen) - hate tour buses.

Marketing and strategy considerations for not creating an adapter aside, it seems easier for Dewalt to design the current generation of tools around the current generation of battery packs.

The 20V Max tools were designed, or at least redesigned, solely around Li-ion battery packs. The only reason I mentioned it is if they had an adapter people have been like hey this makes sense I can keep my old tools and move on to the new and better stuff Dewalt is offering. Now having that cut off may make a person think it might make more sense to sell my old kit and see what the other tool brands are offering.

Your are right no other company did make an adapter either during their transition from stem packs either. We might not be having this conversation if Dewalt had done their conversion closer to when the other brands made the switch. It would be easy to play it off as everyone is doing it.

6 Question Types You WILL Face on the ACT Math Test

I guess its like the old saying you either rip the band aid of really quick or really slow. Especially in this economy, a lot of workers are not upgrading to the latest and greatest. But a lot of people are still buying new tools all the time.

Older tools are wearing down, and battery packs are reaching the ends of their lives. Manufacturers are describing some of these new brushless cordless tools as being just as powerful as cordless tools.

This could also be why Dewalt is expanding their selection of specialty 12V and 12V-compatible tools. Rather than minor upgrades, they waited a little longer and pushed forward major upgrades. Chris saysAug 9, 2013 at 9:49 pmI know brushless has turned a lot of these tools into real good tools, but some of these premium cordless tools are expensive compared to the cheaper more powerful corded counterpartsAnd like you said in this economy, money is everything.

Kinda like the big three waiting on the prius to fail. Now they all get to play catch up with the technology. I dont think Dewalt is letting anyone test the market. They are just following their plan of riding on the contractors market that just flat out cant leave dewalt because they have put out cheap tools that lasted for allong time.The second and third columns in the table above report the percentages relative to the number of responses (second column) as well as respondents (third column).

Thus, the entry 8. Suppose in the above example we were only interested in Coke, Pepsi, and Sprite. As pointed out earlier, one way to code the data in that case would be as follows: COKE PEPSI SPRITE. In other words, one variable was created for each soft drink, then a value of 1 was entered into the respective variable whenever the respective drink was mentioned by the respective respondent. In a sense, we "compact" the three variables Coke, Pepsi, and Sprite into a single variable (Soft Drink) consisting of multiple dichotomies.

All of these types of variables can then be used in crosstabulation tables. For example, we could crosstabulate a multiple dichotomy for Soft Drink (coded as described in the previous paragraph) with a multiple response variable Favorite Fast Foods (with many categories such as Hamburgers, Pizza, etc.

As in the frequency table, the percentages and marginal totals in that table can be computed from the total number of respondents as well as the total number of responses. For example, consider the following hypothetical respondent: Gender Coke Pepsi Sprite Food1 Food2 FEMALE 1 1 FISH PIZZA This female respondent mentioned Coke and Pepsi as her favorite drinks, and Fish and Pizza as her favorite fast foods.

In the complete crosstabulation table she will be counted in the following cells of the table: Food. FEMALE MALE COKE PEPSI SPRITE COKE PEPSI SPRITE X X X X 2 2 This female respondent will "contribute" to (i. Paired Crosstabulation of Multiple Response Variables. A unique option for tabulating multiple response variables is to treat the variables in two or more multiple response variables as matched pairs.

Again, this method is best illustrated with a simple example. Suppose we conducted a survey of past and present home ownership. We asked the respondents to describe their last three (including the present) homes that they purchased. For each home we asked our respondents to write down the number of rooms in the respective house, and the number of occupants. Here is how the data for one respondent (say case number 112) may be entered into a data file: Case no. Rooms 1 2 3 No.

Now suppose we wanted to crosstabulate the number of rooms by the number of occupants for all respondents. We can also treat the two factors in this study (Number of Rooms, Number of Occupants) as multiple response variables. However, it would obviously not make any sense to count the example respondent 112 shown above in cell 3 Rooms - 5 Occupants of the crosstabulation table (which we would, if we simply treated the two factors as ordinary multiple response variables).

ATI TEAS Test Study Guide - Math Review

In other words, we want to ignore the combination of occupants in the third home with the number of rooms in the first home. This is exactly what will be accomplished if we asked for a paired crosstabulation of these multiple response variables. The best way to verify that one understands the way in which the respective tables are constructed is to crosstabulate some simple example data, and then to trace how each case is counted.

The example section of the Crosstabulation chapter in the manual employs this method to illustrate how data are counted for tables involving multiple response variables and multiple dichotomies.
