No, the bat won't fit because 30 divided by 17 equals 1.765
The mean is found by summing all data values and dividing that total by the number of values.
The mean fitness score equals 3.2 points. If every student had the identical score, each student's fitness score would be 3.2 points.
Therefore, the correct choice is D. 3.2 points.
To determine the slope, subtract the y coordinates from each other and the x coordinates as well. That gives us: 10000 - 4000 over 0 - 15, which simplifies to 6000 over -15. When divided, it results in -400. So, the slope amounts to -400. I hope this aids you!:D
The formula for the sum of an arithmetic series is expressed as:
Sn=n/2(a1+an)
where:
n=total terms
a1=the initial term
an=the final term
given
n=18, an=275, Sn=4185
substituting these values into the equation results in:
4185=18/2(a1+275)
after simplification, we obtain:
4185=9(a1+275)
dividing by 9 yields:
465=a1+275
therefore
a1=465-275
a1=190
Conclusion: the first term is 190
Detailed explanation: If the class has 15 boys and 10 girls, this totals 25 students. The likelihood of selecting a girl first would be

. After that selection, there would be one fewer girl and overall student, resulting in the probability for choosing another girl being

. The final probability is obtained by multiplying these two results to yield

.
