Answer:
A. Yes, the table shows a probability distribution.
Step-by-step explanation:
In a probability distribution, none of the values can be negative or over 1. Additionally, all of the values must sum to 1.
Our probabilities are:
0.087; 0.328; 0.416; and 0.169. None of these are negative and none are over 1.
0.087+0.328+0.416+0.169 = 1.00; this means that this is a probability distribution.
Answer:
length = 4x
width = 3x
perimeter = 56 m
also, perimeter = 2 (length + width) [from formula]
therefore, 2(4x + 3x) = 56m
2(7x) = 56m
14x = 56m
x = 56/14 m
x = 4m
Answer:
Step-by-step explanation:
'll just help with proving whether she is correct.
First of all, a fraction divided by a fraction can be made into multiplication since the division of two fractions is kinda difficult
so remember keep, change, flip
keep the first fractions, change the division symbol into multiplication, then flip the fraction i.e. 1/2 becomes 2/1
so 5/2 divided by 1/4 becomes
5/2 * 4/1
which then solved becomes
20/2 which is simplified to 10
Hope this helps :)
There is 17% error in the guess.
Step-by-step explanation:
Given,
Number of marbles in jar = Exact value = 240
Closest guess = Approx Value = 280
Percent error = 
Percent error = 
Percent error = 
Percent error = 
Rounding off to nearest whole percent
Percent error = 17%
There is 17% error in the guess.
