15(.20)= 3 marbles are blue.

15(1/3)= 5 are green

15(.20)= 3 are yellow

3+5+3=11 marbles

15-11= 4 that means the rest of them are red.

The rates of change, true or false​
GenaCL600 [577]

Answer:

Step-by-step explanation:

1 is true because y values are increasing as x increases for both

2 is true because b's rate of change is 2 and a's rate of change is 0.25, so 2/0.25=8.

3 is false because a's y intercept is at 1

tensa zangetsu [6.8K]

Answer:

0.6710

Step-by-step explanation:

The diameters of ball bearings are distributed normally. The mean diameter is 107 millimeters and the population standard deviation is 5 millimeters.

Find the probability that the diameter of a selected bearing is between 104 and 115 millimeters. Round your answer to four decimal places.

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean = 107 mm

σ is the population standard deviation = 5 mm

For x = 104 mm

z = 104 - 107/5

z = -0.6

Probability value from Z-Table:

P(x = 104) = 0.27425

For x = 115 mm

z = 115 - 107/5

z = 1.6

Probability value from Z-Table:

P(x = 115) = 0.9452

The probability that the diameter of a selected bearing is between 104 and 115 millimeters is calculated as:

P(x = 115) - P(x = 104)

0.9452 - 0.27425

= 0.67095

Approximately = 0.6710

I think it is option A. Order matters; if the order is interchanged, the position of the figure will most likely change. You can try it out yourself too! Hope I helped! Happy Holidays!
