If a truck weighs % more than a car, then the truck's weight is %(100 + x) of the car's weight.
If a truck weighs x% more than a car, then the truck's weight is (100 + x)% of the car's weight.
For example, if the car weighs 100 pounds and the truck weighs 20% more, then the truck's weight is 120% of the car's weight, which is 120 pounds.
To calculate the truck's weight as a percentage of the car's weight, you can use the formula: (100 + x)%.

Step-by-step explanation:
p(x≤20)=p(x=-10) +p(x=-5)+p(X=0) +p(x=5) +p(x=10)+ p(X=15)+p(X=20)
This, p(X≤20)=0.20+0.15+0.05+0.1+0.25+0.1+0.15
=1
Step-by-step explanation:
sec(90-A) . Sin A = cot (90-A) . tan(90-A)
cosec X sinA = tanA X cotA
1/sinA X sinA = tanA X 1/tanA
1=1
Hence proved
L.H.S=sec(90-A)·sinA
=cosecA·sinA ;[sec(90-A)= cosecA]
=1/sinA·sinA ;[cosecA=1/sinA]
=1
R.H.S=cot(90-A)·tan(90-A)
=tanA·cotA ;[cot(90-A)=tanA, tan(90-A)=cotA]
=tanA·1/tanA ;[cotA=1/tanA]
=1
thus, L.H.S=R.H.S

Step-by-step explanation:
Answer:
The 95% confidence interval for the true mean speed of thunderstorms is [10.712, 13.688].
Step-by-step explanation:
Given information:
Sample size = 10
Sample mean = 12.2 mph
Standard deviation = 2.4
Confidence interval = 95%
At confidence interval 95% then z-score is 1.96.
The 95% confidence interval for the true mean speed of thunderstorms is
Where, is sample mean, z* is z score at 95% confidence interval, s is standard deviation of sample and n is sample size.
Therefore the 95% confidence interval for the true mean speed of thunderstorms is [10.712, 13.688].
