Answer:
900% or 9 times the size
Step-by-step explanation:
Answer:
4.5cm^2
Step-by-step explanation:
To find area of a triangle the formula is --> 1/2 base times height
so 3cm x 3cm = 9cm and divide by 2 --> 4.5 cm^2
Answer:
H0 : μ2004 - μ2000 = 0
Step-by-step explanation:
Given the data:
Year ________: 2000 ___ 2004
Mean ________ 27.34 ___ 48.12
Std. Dev _______10.11 ____ 19.23
Unweighted n 43 54
The hypothesis is to test if there was a significant difference in the average number of hours worked in a week from 2000 to 2004 ;
Hence, the null hypothesis will negate the hypothesis, that is there is no difference in the average hours worked in a week from 2000 to 2004
Null hypothesis ; H0 : μ2 - μ1 = 0
Alternative hypothesis ; H1 : μ2 - μ1 ≠ 0
First thing to note, QR + RS = QS
#1, RS = 44.6 and SQ = 68.4
Plug in to the equation I wrote above
QR + 44.6 = 68.4
QR = 23.8
#2, RS = 33.5 and RQ = 80
QR + 33.5 = 80
QR = 46.5
