Answer:
12
Step-by-step explanation:
4 centimeters for each present and she used 48 centimeters of tape, so u would take 48 divided by 4 and get 12
Answer:
No only variable on both sides have no solution
Step-by-step explanation:
Then you can get,
for example x=x
or,
y=y
Answer:
81
Step-by-step explanation:
The formula for calculating the sum of geometric series varies depending on the value of its common ratio.
Given the common ratio to be 2/3 which is less than 1, the formula to be used is given as;
Sn = a(1-rⁿ)/1-r
n is the number of terms of the series
a is the first term
r is the common ratio.
Sn is the sum of the series
Given n = 3, r = 2/3 and Sn = 171,
a= ?
Substituting this values in the formula we have;
171 = a{1-(2/3)³}/1-2/3
171 = a{1-8/27}/(1/3)
171 = a(19/27)/(1/3)
171 = 19a/27 × 3/1
171 = 57a/27
57a = 171×27
57a = 4,617
a = 4,617/57
a = 81
The first term of the series is 81
1. The data are
<span>75, 38, 43, 120, 65, 48, 52
Adding them and dividing by the number of data gives the mean which is 63.
Arranging them from lowest to highest and taking the middle data gives the median which is 52.
Since no data is repeated, this means that there is no mode.
The answer is
</span><span>D) mean: 63, median: 52, no mode
2.The answer is
A) mean
3. The realistic data to represent the weight of books is
A) mean </span>
