Answer: C. 10-2
3+7 = 10
So you need to find which value is less than ten
A is wrong because 7+3= 10 and 10 is not less than 10
B is wrong because 9+4 = 11 and 11 is not less than 10
D is wrong because 10-2 = 10 and 10 is not less than 10
C is right because 10-2 =8 and 8 is less than 10
Mean = (89 + 90 + 87 + 95 + 86 + 81 + 102 + 105 + 83 + 88 + 91 + 79)/12 = 1,076/12 = 89.67
a.) 95% C.I. = 89.67 + or - 1.96(0.23) = 89.67 + or - 0.4508 = 89.22 to 90.12
b.) 99% C. I = 89.67 + or - 2.575(0.23) = 89.67 + or - 0.5923 = 89.08 to 90.26
Answer:
2
Step-by-step explanation
If you convert 2/7 to an equivalent fraction, you would get 4/14. Add 4/14 to 13/14 to get 17/14 or 1 and 3/14
5 x 4= 20
8 x 2 = 16
36 + 2 + 2 = 40
40 square inches
Tbe question doesn't state the number of days he walked to school out of 20 school days in the
Month of February.
Answer:
Kindly check explanation
Step-by-step explanation:
To. Obtain the fractional representayion for the number of days he walked to school ;
Let the number of days he walked to school = 10 (this is an hypothesized value)
Number of school days in February = 20
Fraction = 10 /20 = 0.5
The percentage of times walked to school : multiply the fraction obtained above by 100%
0.5 * 100% = 50%
Just put the desired value and proceed uSing the steps described above.
