37 students get at most 67 scores.
The numbers 60-67 represent the lower quartile (lowest 25%). 25% of 60 is 15 not 30. Therefore it is incorrect.
Answer:
Dear user,
Answer to your query is provided below
82300000 in scientific notation = 8.23 × 10^7.
Step-by-step explanation:
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
1 1/7 = 8/7
The lowest common denominator of 8/7 and 1/9 is 63
72/63 : 7/63
72:7
Answer:
Height equation for first student is correct while that of second student is incorrect.
Step-by-step explanation:
Given that the function of height should be quadratic function.
Standard form of Quadratic function is given as,
.
Degree of quadratic function is 2.
Equation of height for first student is given as 
Since, above equation has degree 2 and equation is in quadratic form with value of b and c as 0.
Therefore, height equation for first student is correct.
Equation of height for second student is given as
.
Since the degree of above equation is 1, hence it cannot be the quadratic function. Hence second equation is not an quadratic function.
Therefore, height equation for second student is incorrect.
