A radar measures the speed of a car at 45 miles per hour. The actual speed of the car is 40 miles per hour what is the percent error in the reading of the radar.
Answers
Answer:45
Step-by-step explanation:
step-by-step explanation:
the radar was off by 5 miles per hour, so we need to find what percent 5 is out of 45. percent of (times) if you don’t know how to find that out.
make the assumption that 45 is 100% because it is the output.
next we represent the value we seek with x. so 100% = 45 and x% = 5.
this gives us the simple pair of equations 100% = 45(1) and x% = 5(2).
then multiplying the equations together like 100%/x% = 45/5.
make it into its reciprocal so x%/100% = 5/45. that comes out to be x= 11.11%
5 is 11.11% of 45 so the radar is off by 11.11%

Answer: There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
Two independent variables that could result in a change in the monthly electricity bill are: Physical size of products and Skill level of operators of machines.
Independent VariablesIndependent variables are the determining factors that influence how a dependent variable changes.
For example, monthly electricity bill is a dependent variable which is dependent on the following:
Physical size of productsSkill level of operators of machines.Non-production machines utilizing electricity among others.Therefore, two independent variables that could result in a change in the monthly electricity bill are: Physical size of products and Skill level of operators of machines.

Tina is packing for a five-day trip. She has one blue, one red, one white, one green, and one grey t-shirt. Tina will not wear each t-shirt more than once. What is the probability that Tina will wear blue on the first day of her trip and then wear grey on the second day of her trip?
2/5
1/5
1/20
1/25
Answers
The probability of Tina wearing blue on the first day of her trip and then wearing grey on the second day of her trip is 1/20.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The probability of Tina wearing blue on the first day of her trip is 1/5, since she has 5 t-shirts to choose from and only one of them is blue.
After wearing the blue t-shirt on the first day, Tina will have 4 t-shirts left to choose from for the second day. Only one of those t-shirts is grey, so the probability of Tina wearing grey on the second day given that she wore blue on the first day is 1/4.
The probability of both events happening (Tina wearing blue on the first day and then grey on the second day) is the product of the individual probabilities:
P(blue on first day and grey on second day) = P(blue on first day) x P(grey on second day | blue on first day)
P(blue on first day and grey on second day) = (1/5) x (1/4)
P(blue on first day and grey on second day) = 1/20
Therefore, the probability of Tina wearing blue on the first day of her trip and then wearing grey on the second day of her trip is 1/20. So, the correct option is 1/20.
