Answer:
10 : 3
Step-by-step explanation:
4km = 4000 m
4000 : 1200 = 4000/1200 = 40/12 = 10/3 = 10 : 3
Answer:
convert 4km into meter.

96 = l x w x 8
divide both sides by 8

10 + (8 × 7)
Answers
(8 x 10) + (8 x 7)
Why?
Because when using the distributive property, you distribute the number outside of the parentheses to the numbers inside the parentheses, and in this case, we are multiplying so you will multiply 8 by both 10, and 7.

Answer:
A. 1.49
D. √2
E. five thirds
G. - 0.59
Step-by-step explanation:
In order to be a probability, a value must be at least zero, or at most 1:
Evaluating each of the given values:
A. 1.49
1.49 is at least zero but it is greater than one, therefore 1.49 cannot be a probability.
B. 1
1 represents a probability of 100%, therefore this value can be a probability
C. three fifths
Can be a probability
D. √2
Cannot be a probability
E. five thirds
Cannot be a probability
F. 0
0 represents a probability of 0%, therefore this value can be a probability
G. - 0.59
Negative values cannot be probabilities.
H. 0.04
Can be a probability
Final answer:
Probabilities are values ranging from 0 to 1, inclusive. With this in mind, values 5/3, √2, -0.59, and 1.49 cannot be probabilities as they're either below 0 or above 1.
Explanation:
In the field of mathematics, specifically in statistics, a probability represents the likelihood of an event occurring and is always a value between 0 and 1, inclusively. The value 0 means that an event will not happen, whilst 1 means the event is certain to happen. Therefore, any value less than 0 or greater than 1 cannot be a probability.
Given the values: 0.04, 5 divided by 3, 1, 0, 3 divided by 5, √2, negative 0.59, and 1.49, the values that cannot be probabilities are:
- Value 5 divided by 3 (which equals approximately 1.67)
- Value √2 (which equals approximately 1.41)
- Negative 0.59
- 1.49
These numbers do not lie within the range of 0 to 1, and hence, cannot represent probabilities.
