Answer:3 & 4
Step-by-step explanation: those are the two with multiplication/division
Celine has already knitted 0.8 meters. Her final result should be 1.2 meters.
To calculate how many meters Celine has to knit we should subtract the alreadu knitted length of scarf from the entire length. This give the equation:\
X=1.2m-0.8m
X is the unknown
X=0.4 meters
It only falls inside the trapezoid bc the circle goes through the point (0,2) so it isnt on 1.5
Answer:
H0 : μ1 = μ2
H0 : μ1 < μ2
Step-by-step explanation:
Given :
Early studiers, group 1, mean μ1
Late studiers, group 2 ; mean, μ2
To test the claim that students who study earlier have an average score that is less than the average score for students
The null hypothesis ; there is no difference in average score
H0 : μ1 = μ2
Alternative hypothesis is early studiers means is less than average score of late studiers
H0 : μ1 < μ2
The circumference of a circle:
2丌r
In this case, the radius:
10.4÷2
=5.2cm
The circumference
=2兀(5.2)
=2(5.2)兀
=10.4兀
Therefore the answer is 10.4兀.
Hope it helps!
