Let us assume that the given speed is in miles per hour.
A race car is driven by a professional driver at 99 mph.
We have to find the speed in kilometer per hour and kilometer per minutes
As 1 mile = 1.61 km
So, 99 miles = 
kmph
1 km per hour = 0.0166 km per minute
So, 159.39 kmph = 
km per minute
Hence, The speed is equivalent to 159.39 kilometers /hour, or 2.645 kilometers/minutes .
The number 2*2*2*4*5 is not in its prime factorization because not all the factors are prime numbers. A prime number is a number that has no other factors except for 1 and itself.
4 is not a prime number, since it can be divided by 2. The number can be broken down into its prime factors by dividing by 2, and it becomes 2*2.
Therefore, the factorization of the number 2*2*2*4*5 can be broken down to 2*2*2*2*2*5.
Answer:
D) a chi square test for independence.
Step-by-step explanation:
Given that we suspect that automobile insurance premiums (in dollars) may be steadily decreasing with the driver's driving experience (in years), so we choose a random sample of drivers who have similar automobile insurance coverage and collect data about their ages and insurance premiums.
We are to check whether two variables insurance premiums and driving experience are associated.
Two categorical variables are compared for different ages and insurance premiums.
Hence a proper test would be
D) a chi square test for independence.

Answer:
4a + 4b = 10
6a + 6b = 12
Step-by-step explanation:
Putting the equation in a system of linear equation :
We donate, apples and oranges using any preffered letter or alphabet
Let :
Apples = a ; oranges = b
4 apples and 4 oranges equals $10
4a + 4b = 10
6 Apples and 6 oranges equals $12
6a + 6b = 12
Hence, the system of linear equation :
4a + 4b = 10
6a + 6b = 12
