Answer:
The range of the given data set is 6.
Step-by-step explanation:
Range of the data set provides us with some basic information regarding spread of the data.
It is commonly used and quite easy to find.
First step is to arrange the values from the lowest to the highest.
It is already given arranged, so that will savd us some time.
Next step is simply subtracting the two values on the extremes, or, simply put, subtract the lowest from the highest value.
So, the range in this case would be 7-1=6.
Answer:
△ VUW = △ KJI
Step-by-step explanation:
In △ VUW, △ KJI,
UW = JI ( Sides are equal )
∠ VUW = ∠ KJI ( From the diagram )
∠ UWV = ∠ KIJ ( From the diagram )
By ASA rule of congruency,
△ VUW is congruent to △ KJI.
Answer:
77,936
Step-by-step explanation:
To find the mean, add up all the numbers, then divide by that amount of numbers. So, 12,274 + 12,368 + 12,544 + 12760 + 12,911 + 13,162 + 13,419 = 89,438/ 7 = 77,936.
Because this is a triangle, all three angles put together equals 180 degrees.
We can add the angles together and set them equal to 180 to solve for the value of y.
y + y - 12 + 56 = 180
Combine like terms.
2y + 44 = 180
Subtract 44 from both sides.
2y = 136
Divide both sides by 2.
y = 68
<u>The value of y is equal to 68 degrees.</u>
Answer:
We know that the angle of elevation is
