Answer:
Mean deviation of 80, 88, 93, 95 is 5
Step-by-step explanation:
Step 1: find the mean
Mean = Sum of items/ Number of items
Mean = 80+88+93+95 = 356
Mean = 356 / 4 = 89
Step 2: find the mean deviation
Mean Deviation = ∑i = 0n |xi − μ| / N
Mean Deviation = | (89-80) + (89-88) + (89-93) + (89-95) | /4
Mean Deviation = 5
1.5x+4y=784
x+y=306
1.5x+4(306-x)=784
1.5x+1224-4x=784
1224-2.5x=784
-2.5x=-440
x=176
now do y=306-176
your answer is 130.
Domain is how far it travels in the x axis. for this, it would be [0, infinity) usually you’d use an infinity sign, but i can’t find that on my phone. range is same as domain but for y axis. so here it’ll be (-infinity, infinity). you use these [] when you can be on the number. you use there () when you can’t be on the number (or it’s infinity). you use {} when you want to list them.
Answer:
Area of the triangle =(height x base ) /2
A=(17x12)/2
A=102
the area of the triangle is 102
