The scenarios matched up are as summarized:
1 is matched with E
2 is matched with D
3 is matched with F
4 is matched with A
5 is matched with C
and lastly 6 is matched with B
X=Juliana's age
r=Rich's age
(x+2)+(x*3)+5=R
You can solve it from there
Answer:
(−14.850850 ; 0.565135)
Step-by-step explanation:
Confidence interval :
Xd ± Tcritical * Sd/√n
Population 1 :30 35 23 22 28 39 21
Population 2 : 45 49 15 34 20 49 36
d = -15,-14,8,-12,8,-10,-15
The mean of d, Xd = Σx / n = - 7.14285714
The standard deviation of the difference, Sd = 10.4948967 (using calculator)
Sample size, n = 7
Tcritical at 90%, df = 7 - 1 = 6
Tcritical = 1.943176
Confidence interval :
- 7.14285714 ± 1.943176 * 10.4948967/√7
Confidence interval :
- 7.14285714 ± 7.7079925
(−14.850850 ; 0.565135)
Answer:
39
Step-by-step explanation:
We notice this is an arithmetic sequence.
14, 9, 4.
common difference = d = 14 - 9 = 5
first term a_1 = 14
Find 6th term a_6
a_n = (n -1)*d + a_1
a_6 = (6 -1)*5 + 14
a_6 = 5*5 + 14 = 25 + 14 = 39
Step-by-step explanation:
The result is 12 cm³ because to get the volume of a figure you have to multiply all the characters
