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 have a shuffled deck of 52 playing cards. A deck of cards has four different suits, with an even number of cards in each. I pi
zzz [600]

Answer:

The probability is 0.25

Step-by-step explanation:

Here is a probability question.

We want to know the probability of picking a card which is in the spades suit.

Now, what we know is that there are a total of 52 cards and we have 4 suites.

Each suite have equal number of cards. So definitely the number of cards in the spades suit will be 52/4 = 13 cards

Thus, the probability of picking any card in the spades suit = number of cards in the spades suit/ Total number of cards in the deck

Mathematically that would be 13/52 = 1/4 = 0.25

Write the equation of the line passing through points (2, - 2) and (1, 0) in slope intercept form
Arte-miy333 [17]
First find the slope
(0+2)/(1-2) = 2/-1 = -2
Y = mx + b
Y = -2x + b
Plot in any point
-2 = -2(2) + b, b = 2
Solution: y = -2x + 2

HELP PLEASE 3. Simplify the expression (5 points)<br> [(7 + 3) • 5 - 4] = 2 + 2
krok68 [10]

Answer: 46 or 46=4

Step-by-step explanation:

Do what's in the Parenthesis first so 7+2=10 which now give you the equation

[10x 5-4]=2+2

Now we Multiply so we do 10x5 which is 50 so that now gives us the equation[50-4]=2+2

Now we add the 2+2 which is 4 giving us the equation [50-4]=4

Now we subtract 50-4 giving 46

46=4
