<em>The range of the data shown in the box plot is 32.</em>
Median: 74
Highest value: 82
Lowest value: 50
Range: 82 - 50 = 32
It’s 45%
Explanation = 31900-22000/22000 • 100 = 45%
Answer:
And for the other case if we use the z score and the complement rule we have:
And we can find the probability of interest like this:
And replacing we got:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
We assume that the distribution is
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we find the individual probabilities we got:
And for the other case if we use the z score and the complement rule we have:
And we can find the probability of interest like this:
And replacing we got:
Answer:
awww well look at that my best friend is on brainly, i need help too <3
Step-by-step explanation:
Answer: The correct answer is: [A]: " x = - 1/2 " .

Step-by-step explanation:
_______________________
Given:
4x − 6 = 10x − 3 ; Solve for "x" ;
Let us add "3" to each side of the equation;
and subtract "4x" from each side of the equation:
______________________
4x − 6 + 3 − 4x = 10x − 3 + 3 − 4x ;
______________________
to get:
______________________
-3 = 6x ;
______________________
↔ 6x = -3 ;
______________________
Now, divide Each Side of the equation by "6" ;
to isolate "x" on one side of the equation;
and to solve for "x" ;
______________________
6x / 6 = - 3 / 6 ;
to get:
x = - 3/ 6 ;
.
______________________
→ which is: Answer choice: [A]: " " .
