Answer:
These two samples are independent samples.
Step-by-step explanation:
Each object would then have two weight values (one from scale 1 and one from scale 2). Based on the nature of the differences in the two weight measurements for the 30 objects, the two scales may be compared.
These two samples are independent samples.
Though the objects are same but the scales are different.
Percent means parts out of 100
15%=15/100
'of' means mutily
15% of 60=15/100 times 60=900/100=90/10=9/1=9
easy way is
15%=10%+5%
10% of 60=6
5%=1/2 of 10%
10%=6, 1/2 of 6=3
10%+5%=6+3=9
answer is still 9
To find volume you use the formula
Volume=base× height
the base is 6×5
he height is 11
Volume=(5×6)×11
Volume=30×11
Volume=330 cubic centimeters
Answer:
16 cm
Step-by-step explanation:
Circumference of a circle
We are told that the string is wound symmetrically around a circular rod.
Now, the circumference of the rod is 4 cm and length is 12 cm.
Now, circumference is also the length of a circle. Thus, one wound of the string will be equal to the circumference of the rod.
Thus, one wound = 4 cm
Since the string makes 4 turns about the rod, then;
Length of string = 4 × 4 = 16 cm
