Answer:
(1,5)
Step-by-step explanation:
2x-3(x+4)=-13 y=1+4
2x-3x-12=-13 y=5
-x-12=-13
+12
-x=-1/-1
x=1
To get from 3 to 4 it’s 4/3
so 5.2 x 4/3 = 6.9 (1 d.p.)
6.9 - 5.2 = 1.7
X= 1.7
sorry If this is wrong :/
Answer:
10 square meters
Step-by-step explanation:
You can find the volume of a cylinder by multiplying the area of its base by its height. This can be shown by the equation: v = (pi(r^2))h, or 140 = 14x
If you divide 140 by 14, you can get the area of its base.
Answer:
t = 34.548
Step-by-step explanation:
Here X₁ = Solid values / n
= 26.3 +25.3+26.1+25.6+26.7+25.9/6
=155.9 / 6
=25.984
X₂ = Liquid values/n
= 16.9 +16.6+16.5+17.4+17.4+17.2 / 6
=102/6 = 17
Formula for the sample standard deviation is

we get
s₁ = 0.49967
s₂ = 0.3949
Construction of hypothesis
H₀ :μ₁ = μ₂
H₁ : μ₁ ≠ μ₂
Apply test statistic formula we get the value

putting all these values
t = 25.984 - 17 / √ (o.49967)²/6 + (0.39497)²/6
t = 34.548
Answer:
I'm not to sure, but I'll say 10.5
If you multiply 3.50 x 3 you'll get 10.5
If you add you'll get 13.5.
If it's an addition I'll recommend to go with 13.5
If it's a multiplication I'll recommend to go with 10.5
