Answer:
383 students
Step-by-step explanation:
Average IQ = 115
So for IQ of 145 it's not average again.
So , 145 IQ should be 1/4 of the total number because it's no longer average .
So 1/4 of 1531 = 382.75 students approximately = 383 students
This answer is based on the assumption that average IQ is around 115.
So any one with IQ of 145 is not longer an average person concerning IQ.
Answer:
The probability of getting an odd number when the spinner is spun, is p(even number) = 1/2
Step-by-step explanation:
Given that the spinner has 12 equal sections labelled 1-12
Let S be the sample space
Then
S = {1,2,3,4,5,6,7,8,9,10,11,12}
Let A be the event that the outcome is an even number
Then
A = {2,4,6,8,10,12}
The probability of A will be given as:
Hence,
The probability of getting an odd number when the spinner is spun, is p(even number) = 1/2
Answer:
x+6 ≥ 25
Step-by-step explanation:
The product means the sum of <em>x</em> + 6. In this question, <em>x</em> + 6, is greater than or equal to the number 25 which is what ≥ means. Meaning, <em>x</em> can be replaced by a number that when added to <em>6</em>, <u>will equal to </u><u><em>25</em></u><u> or more</u>. For example, <em>x </em>can equal <em>19, 20, 21 </em>and so on.
