-14°C
Step-by-step explanation:
Given that,
The mean temperature for the first 4 days in January was -4°C.
The mean temperature for the first 5 days in January was -6°C.
Mean = sum of observations/no. of observations
For first 4 days,
For first 5 days,
Let the temperature on 5th day is T. So,
Put S₄ = -16 in equation (2).
-16 + T = -30
T = -30+16
T = -14°C
So, the temperature on the 5th day is -14°C.
-12 degrees.
Step-by-step explanation:
We remember that to calculate the average, we must add all values, then divide by the amount of values.
This means the first 4 days sum to -8 while the first 5 days sum to -20. Therefore, on the fifth day, the temperature was -12 degrees.
SI=(P*R*T)/100
P=2000
R=1.5
T=6
SI=(2000*1.5*6)/100
=(2000*9)/100
=180

The answer is in the image
The total nom of code that can be used is equal to 5+3 = 8
For every 8 cars there are 7 trucks
Therefore,
Cars:Truck=8:7
Answer is B)8:7
The solution is in the following image
y=2x+15
where y=Value of coin
x=Age in years
Value of coin after 19 years=2*19+15
=$53
Therefore, Value after 19 years=$53
F=ma
where F=force
m=mass
a=acceleration
Here,
F=4300
a=3.3m/s2
m=F/a
=4300/3.3
=1303.03kg
