Jamaal using whole interval type of data recording to collect the data on Freddie’s on-task behavior.
What do you mean by whole interval data collection?One form of interval recording technique is whole interval recording. An interval recording approach involves watching to see if a behavior happens or not within predetermined intervals of time. After determining the duration of an observation session, the time is divided into shorter segments that are all of the same length. To record the incidence of behavior, ten boxes may be utilized to divide a 10-minute observational session into 1-minute intervals. A whole interval recorder uses a X for occurrence and a O for no non-occurrence to indicate if a behavior occurred during the entire interval.

Gabriel started training with the track team five weeks ago. During the first week, he ran 0.5 mile at each practice. The next three weeks he ran 0.75 mile, 1 mile, and 1.25 miles at each practice. If he continues this pattern, how many miles will he be running at each practice during the 7 th week?
If Gabriel continues the pattern of running that he has done on the past four weeks, the miles he will run on the 7th week is 2 miles.
How many miles will Gabriel run?Gabriel's pattern of running is such that he increases the number of miles by 0.25 miles every week.
This is why he ran 0.5 miles, and then 0.75 miles and then 1 mile.
If he keeps going like this, one the 7th week, he will run:
5th week = 1.5 miles
6th week = 1.75 miles

Emma has $12.60 worth of nickels and quarters. She has 4 times as many quarters as
nickels. How many quarters does she have?
On solving linear equation 1.05x=12.60, we get that Emma has 48 quarters.
What is linear equation in one variable?Let x be any variable then ax + b = c b is an linear equation in one variable.
where a, b, c are constants then we get solution for x as
x=(b-c)/a
Given as Emma has 4 times as many as quarters as nickels
Let the no of nickels be x
Then as there are 4 times as many as quarters as nickels
then no quarters be = 4x
Value of one nickel = 5 cents= $0.05
Value of one quarter = 25 cents = $0.25
Therefore x nickels and 4x quarters worth is = x(.05)+4x(.25)
Total worth of given nickels and quarters = $12.60
Then 0.05x+x = 12.60
This is an linear equation in one variable
1.05x=12.60
x= 12.60/1.05
x=12
Therefore ,Emma has 12 nickels
and 4(12)= 48 quarters

What is an integer?The collection of positive and negative integers is known as an integer. Integers, like whole numbers, do not include the fractional portion. Integers can therefore be defined as numbers that can be positive, negative, or zero but not as fractions. On integers, we can carry out all arithmetic operations, including addition, subtraction, multiplication, and division. Integer examples include 1, 2, 5, 8, -9, -12, etc. "Z" stands for an integer. The Latin term "Integer," which implies entire or intact, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.
Integer examples include: -1, -12, 6, and 15.
Zero is not an integer that can be positive or negative. There is no (+ or -) sign on zero, making it a neutral number.

the distribution of iq (intelligence quotient) is approximately normal in shape with a mean of 100 and a standard deviation of 15.according to the standard deviation rule, % of people have an iq between 55 and 145. do not round.
According to the standard deviation rule, 99.7% of people have an IQ between 55 and 145.
How to use the Empirical Rule in statistics?The standard deviation rule which is the empirical rule in statistics tells us that for distributions that have the normal shape, approximately 99.7% of the observations will fall within 3 standard deviations of the mean.
Now, In this question the mean is 100, and the standard deviation is 15. Thus, we can say that approximately 99.7% of the observations (IQ scores) fall between 100 − (3 * 15) and 100 + (3 * 15) or between 55 and 145.
Now, approximately 100% − 99.7% = 0.3% of the observations fall outside this interval. Since the normal shape is symmetric, approximately 0.15% of the observations fall above 145.

thirty automobiles were tested for fuel efficiency in miles per gallon. the following frequency distribution was obtained. construct a histogram
For the given data, x1 = (8 + 12)/2 = 10;
Mean = Sum of frequencies*components/Sum of frequencies = 590 / 30 = 19.6667
What is a Histogram?A histogram roughly depicts the distribution of numerical data. Karl Pearson is credited with coining the phrase. To create a histogram, you must first "bin" (or "bucket") the data range, divide it into a series of intervals, and then count how many values fall into each interval. The bins are often defined as discrete intervals that don't overlap. The bins (intervals) must be next to each other and are frequently (but not necessarily) of the same size.
When the bins are the same size, a rectangle is constructed across each bin, with the height being proportional to the frequency—that is, the number of cases in each bin.

Namely, { |x|=x}{ |x|=x} if x is a positive number, and {|x|=-x}{ |x|=-x} if { x}x is negative (in which case negating { x}x makes { -x}-x positive), and { |0|=0}{ |0|=0}.The absolute value of a number may be thought of as its distance from zero.
For example, an absolute value is also defined for the complex numbers, the ordered rings, fields and vector spaces.
