Tia Veronica Pam and Lily are sisters. Tia is eight years old and she’s two years older than Pam. Pam is five years younger than

Nastasia [14]

Answer:

Pam (6 years), Tia(8 years), Veronica(11 years) , Lily (15 years)

Step-by-step explanation:

Age of Tia = 8 years

______________________________________________

Given Tia is 2 years older than Pam

mathematically

age of Pam + 2 years = age of Tia

age of Pam + 2 years = 8 years

age of Pam = 8 years- 2 years = 6 years

______________________________________________

Given Pam is five years younger than Veronica

we can infer that age of veronica is age of Pam + 5 more years

mathematically

age of Pam + 5 years = age of Veronica

6 years + 5 years = age of Veronica

age of Veronica = 11 years

______________________________________________

Given Veronica is four years younger than Lily

we can infer that age of Veronica is (age of Lily - 4 years)

mathematically

age of Veronica = age of lily - 4 years

11 years = age of lily - 4 years

age of lily = 11 years + 4 years = 15 years

age of lily = 15 years

______________________________________________

Arranging the list from youngest to oldest we have

age of Pam = 6 years

Age of Tia = 8 years

age of Veronica = 11 years

age of lily = 15 years

Arranging sisters in order of youngest to oldest

Pam, Tia, Veronica , Lily

In the diagram, transversal t cuts across the parallel lines a and b. Match the pairs of angles with the relationship that shows

charle [14.2K]

we know that

case a) alternate exterior angles

m∠2=m∠7 --------> by alternate exterior angles

m∠1=m∠8 --------> by alternate exterior angles

case b) alternate interior angles

m∠3=m∠6 --------> by alternate interior angles

m∠5=m∠4 --------> by alternate interior angles

case c) corresponding angles

m∠1=m∠5 --------> by corresponding angles

m∠3=m∠7 --------> by corresponding angles

m∠2=m∠6 --------> by corresponding angles

m∠4=m∠8 --------> by corresponding angles

case d) vertical angles

m∠1=m∠4 --------> by vertical angles

m∠2=m∠3 --------> by vertical angles

m∠5=m∠8 --------> by vertical angles

m∠6=m∠7 --------> by vertical angles

therefore

A shipment of ball bearings with a mean diameter of 25 mm and a standard deviation of 0.2 mm is normally distributed. By how man

Svetach [21]

You need to calculate how many times the required difference is of the standard deviation, i.e. the ratio difference / standard deviation.

These are the calculations:

Standard deviation = 0.2 mm

Difference between 25.6mm and the mean = 25.6mm - 25mm = 0.6 mm

Ratio difference / standard deviation = 0.6mm / 0.2 mm = 3.

Then, the answer is that a ball with a diameter of 25.6 mm differs 3 standard deviations from the mean.

The multiplication law is potentially helpful when we are interested in computing the probability of a. mutually exclusive event

Korvikt [17]

Answer:

b ) the intersection of two events

Step-by-step explanation:

Gary and Steve are both hosting . There are 50 buttons total, 15 buttons are blue and 27 buttons are red. Gary puts all of the buttons into a bag. Steve and Gary both want to wear red buttons.What is the probability ? To solve this problem, you need to understand the Multiplication Rule of Probability.This probability means to find the probability of the intersection of two events, multiply the two probabilities.

Probability of two events occurring that is called intersection of two events. There are two different set of events , called independent and dependent events.

Independent events event is not affected by a previous event.

A dependent event is when one event influences the outcome of another event . To find the intersection of two events, whether they are independent or dependent, multiply the two probabilities together.
