Answer:
the answer is in the explanation
Step-by-step explanation:
we are given
sample size
= 10 for each formulation
mean
(formulation 1) = 121
mean
(formulation 2) = 112
s (standard deviation ) = 8 mins for each case
null hypothesis
μ2 = μ1 (both have average same time)
alternative hypothesis
μ2 < μ1
under
the test statistics is

t = -2.5
ItI = 2.5
The P-value at ItI = 2.5 at
= 0.05 μ = 0.010699

Answer:
£39.20
Step-by-step explanation:
2+1+5=8
£78.40/8 = 9.8
9.8*5= 49
49-9.8= 39.2
Answer:
Erin ran 12.5 miles
Luis ran 7.5
In all they ran 20 miles.
Step-by-step explanation:
Erin: 5 x 3.5 = ?
Luis: 3 x 2.5 = ?
----------------------------
5 x 2.5 = 12.5 . Erin ran 12.5 miles
3 x 2.5 = 7.5 . Luis ran 7.5 miles
7.5 + 12.5 = 20 miles
They ran 20 miles all together.
Hope this helps!
Answer:
We conclude that the area of the right triangle is:

Hence, option A is correct.
Step-by-step explanation:
From the given right-angled triangle,
Using the formula to determine the area of the right-angled triangle
Area of the right triangle A = 1/2 × Base × Perpendicular

Factor 2p-6: 2(p-3)
Divide the number: 2/2 = 1





Therefore, we conclude that the area of the right triangle is:

Hence, option A is correct.
Yes the graph will show a proportional relationship
