Answer:
z = 1.5
Step-by-step explanation:
x - mean
standard score = -----------------
6
Substituting 74 for x, 65 for mean, we get:
74 - 65
standard score = ----------------- = 9/6 = 1.5
6
The pertinent z-score (standard score) is 1.5.
The answer is 16 and you can find that by counting the squares inside (that’s the easiest way to find the answer) hope that helps
Answer:
-46.3
Step-by-step explanation:
Mean is when you add all the numbers in the set together then divide it by how many numbers are in the set.
-44 + (-48) + (-43) + (-50) = -185
-185/4 = -46.25
When rounded -46.25 would be -46.3
Answer:
25
Step-by-step explanation:
4 : 5. is ratio before two apples were removed.
2 : 3. is ratio after two apples were removed.
combing the two statements will give you the following mathematical statement:
4x-2:5x=2:3 solve for x
3(4x-2)=5x*2
12x - 6=
2x=6
x=3
then 4x + 5x = total ñô fruit
4(3) + 5(3) = total ñô fruit
27= total ñô fruit
remaining fruit=total ñô fruit - 2
remaining fruit=27-2
remaining fruit=25
