A C B, X Z YIs there enough information to prove that the triangles are congruent?
If yes, provide the correct Triangle Congruence Postulate or Theorem and a
congruence statement.
If no, justify your answer.

Answer:

The answer will be 0=0. This means that the equation will always be true.

Final answer:

The question is a quadratic equation that can be solved by first simplifying, setting to equal zero, and finally using a method like factoring, completing the square, or the quadratic formula.

Explanation:

To solve the equation 3 (2d-1) 2d= 4(d-2) + 5, firstly, you'll need to distribute the expressions inside the brackets on both sides: 6d² - 3d = 4d - 8 + 5. Simplify to get 6d² - 3d = 4d - 3.

Next, set the equation to equal zero: 6d² - 3d - 4d +3 = 0, which simplifies further to 6d² - 7d + 3 = 0.

Now, you can solve this quadratic equation either by factoring, completing the square or using the quadratic formula (if it's difficult to factor).

Answer:

80% confidence interval for the average age of people who attend U of O football games is [42.795 , 44.604].

Step-by-step explanation:

We are given that a sample of 100 attendees and find the average age to be 43.7 years old with a standard deviation of 7 years.

So, the pivotal quantity for 80% confidence interval for the population average start up cost is given by;

          P.Q. = ~

where, = sample average age = 43.7 years old

             = sample standard deviation = 7 years

            n = sample of attendees = 100

             = population average age of people

So, 80% confidence interval for the average age of people, is ;

P(-1.2915 < < 1.2915) = 0.80

P(-1.2915 < < 1.2915) = 0.80

P( < < ) = 0.80

P( < < ) = 0.80

80% confidence interval for = [ ,  ]

                                                 = [ , ]

                                                 = [42.795 , 44.604]

Therefore, 80% confidence interval for the population average age of people who attend U of O football games is [42.795 , 44.604].

Answer:

49 days

Step-by-step explanation:

The spread of the disease is modeled as

where n = number of infected people

t = time (in days)

When the number of infected people is 1400, the number of days t will be:

It will take 49 days for the number of infected people to reach 1400.

Final answer:

Given the function n=200 Square root t where n is the number of infected, and t is time, it will take 49 days for the number of infected people to reach 1400.

Explanation:

To find out how long it will take until the number of infected people reaches 1400, we are going to set n = 1400 (number of infected people) in the given equation, and then solve for t (time in days).

So, 1400 = 200 √t. Dividing both sides by 200, we get √t = 7. Then, squaring both sides give us t = 49 days. So, it will take 49 days for the number of infected people to reach 1400.

Given the function n=200 Square root t where n is the number of infected, and t is time, it will take 49 days for the number of infected people to reach 1400.

Answer:

D

Step-by-step explanation:

if AB is congruent to AC that means both are 76 degrees so subtract that from the total degrees of a whole triangle which is 180 that gives you A which is 28.
