What is the length of a spool of ribbon with a z-score of 0.7?

Enter your answer, rounded to the nearest tenth, in the box.

the length of a spool of ribbon with a z-score of 0.7 is 92.3 cm

Step-by-step explanation:

Here we have , The lengths of spools of ribbon are normally distributed with a mean of 91.4 centimeters and a standard deviation of 1.3 centimeters.  What is the length of a spool of ribbon with a z-score of 0.7 . Let's find out:

According to Question we have following parameters as :

X = the length of a spool of ribbon

Mean(x) = 91.4 cm

standard deviation(y) = 1.3 cm

Z = 0.7

We know that Z score is given by :

⇒

⇒

⇒

⇒

Therefore , the length of a spool of ribbon with a z-score of 0.7 is 92.3 cm

the answer is x equals 50, this is because the two angles are the same measurements because they are vertical angles. in corresponding angles, vertical angles are two angles with one diagonally above another. those two angles will be the same measurements.

110 - 10 = 100

100 / 2 = 50

x   = 50

110 = 2(50) + 10 = 110

110 = 110
