Answer:

Given sequence is 2,5,8,11,.....

Here t

1

=2,t

=5,t

=8,t

=11

2

=2+1×3=5

=2+2×3=8

4

=2+3×3=11

Clearly it is an AP with first term a=2 and common difference d=3

t

n

=a+(n−1)d

∴t

5

=2+4×3=14

Hence, the answer is 14.

Solve for x: −2x − 4 &gt; 8
Pavlova-9 [17]
To solve for x in an inequality is very similar to solving for x in an equation since for both you would need to isolate x. 

step 1) -2x-4>8               add the 4 over to move any constants over to the                         +4 +4              other side.
             -2x> 12

step 2) x< -6                 Divide out the -2 to isolate x, however, keep in mind,                                      when you divide or multiply over any negative                                                   number, you must also remember to flip the inquality                                      sign.

Classify the following data. Indicate whether the data is qualitative or quantitative, indicate whether the data is discrete, co
ruslelena [56]

Answer:

  1. <u>Quantitative.</u>
  2. <u>Discrete.</u>
  3. <u>Interval Scale.</u>

Step-by-step explanation:

  1. The IQ scores are measured numerically. This makes it quantitative data. Quantitative data provide numerical measures which can be used to perform arithmetric operations such as addition, subtraction, multiplication and division. Results from these kind of data can be used to provide meaningful and explanatory results to certain phenomena.
  2. IQ scores are discrete because they are always expressed as integers. that is in whole numbers and not in fractions e.g 100, 120, 60.
  3. The level of measurement is on an interval scale because the difference between values have meanings. Larger values mean higher IQ. for example, the difference in IQ numbers between two people for represents something real.
