Which congruence theorem can be used to prove ABR = RCA?

1 answer:

8 0

Answer: The HL Theorem can be used to prove ABR ≅ RCA because both triangles share the same hypotenuse and a leg. The HL theorem states that If the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

galben [10]

To find out how many 3 course meals there are you will multiply all three numbers together. The reason for this is that you can group each item with each of the other options. This is a triple grouping.

4 x 4 x 5 = 80

There are 80 possible combinations.

(a) Suppose one house from the city will be selected at random. Use the histogram to estimate the probability that the selected

Mila [183]

Answer:

a) 0.71

b) 0.9863

Step-by-step explanation:

a. Given the mean prices of a house is $403,000 and the standard deviation is $278,000

-The probability the probability that the selected house is valued at less than $500,000 is obtained by summing the frequencies of prices below $500,000:

$P(X$

Hence, the probability of a house price below $500,000 is 0.71

b. -Let X be the mean price of a randomly selected house.

-Since the sample size 40 is greater than 30, we assume normal distribution.

-The probability can therefore be calculated as follows:

$P(X$

Thus, the probability that the mean value of the 40 houses is less than $500,000 is 0.9863
