Answer:
D. 2.33.
Step-by-step explanation:
Given;
the weight distribution of the bottles = 4, 2, 5, 4, 5, 2, and 6
sum of the weights = 28
the mean (x) = 28/7
x = 4
the sum of square of the mean deviation is calculated as:
= (4 - 4)² + (2 - 4)² + (5 - 4)² + (4 - 4)² + (5 - 4)² + (2 - 4)² + (6 - 4)²
= 0 + 4 + 1 + 0 + 1 + 4 + 4
= 14
Therefore, the correct answer is D
Answer:
The value of x would be -3.
Step-by-step explanation:
Consider the complete question is,
'Which represents all the values of x that make the rational expression undefined?'
Since, the rational expression is defined for all real values except those for which denominator is equal to zero,
If 3x + 9 = 0,
3x = -9
Hence the values of x that make the rational expression undefined would be -3.
Answer:
x = 16
Step-by-step explanation:
From the first statement, we can say that:
Angle A is equal to angle D,
Angle B is equal to and E.
Since measure of Angle B and E are given and they are equal, we equate them and solve for x.
Hence x = 16
Answer:
<h2>The last costumers got 2.25 kilograms of chocolate candies.</h2>Step-by-step explanation:
The question is
<em> There is 11.73 kg of chocolate candies in the grocery store. The first customer bought 48 dag of candies. A second customer bought 4/5 of the remaining quantity. The last three customers bought the same amount of candy. How much chocolate did the last customers get?</em>
<em />
Givens
Let's transform 48 dag to kilograms.
Therefore, the first costumer bought 0.48 kilograms of candies.
The remaining amount is:
Now, we need to multiply the remaining amount of candies with 4/5
Therefore, the second costumer bought 9 kilograms of chocolate candies.
At last, we need to find the new remaining part of candies, which is
Therefore, the last costumers got 2.25 kilograms of chocolate candies.
Step-by-step explanation:
if that's what you mean
