Answer:
+1.12 and -1.12
Step-by-step explanation:
Let the two z scores be 
.
Since the two Z-scores that separate the middle 73.72% on the Standard Normal Curve, this can be represented by the equation:
From the z table of the normal distribution, z₁ = 1.12. That is a z score of 1.12 gives 0.8686.
The two z scores are +1.12 and -1.12 = ± 1.12
Hello there! Ashton needs 48 more dollars.
Well, to start, you want to find 60% of 120. To do this, you first have to convert 60% into a decimal by dividing it by 100.
60/100 = 0.6
Next, multiply 0.6 by your total needed, 120, to finish finding 60% of 120.
120 x 0.6 = 72.
So he already has 72 dollars, but how many more does he need? You can find this by subtracting 72 from 120.
120 - 72 = 48.
So, this means he needs 48 more dollars. I hope this helps and have a great rest of your day! Please let me know if you need further help with this question. :)
Answer:
x = 5; y = 138, z= 42
Step-by-step explanation:
4x- 17 = 3 [ opposite sides of a parallelogram are equal]
4x = 3+ 17 = 20; X= 20/4 = 5
138 + Z = 180( angle on a straight line)
Z is an alternate angles to the remaining angle off 138 forming the straight line.
z= 180-138 = 42 degrees
Y = 138 [ opposite angles of a regular quadilareral been equal]
The slope is 3/2(
0,4) and (2,7) the distance is 3 rising and 2 to the side. Remember rise over run so I would be 3/2
