The diagram below shows triangles. JKL and JMN drawn within a larger triangle JLN. Namira claims that triangles. JKL and JMN are similar. Select ALL statements that can be used to show that triangles JKL and JMN are similar,
A mZJ+mZJLK = 90
B
mZJLK = mZJNM = 22
С
ZKLNand ZMNL are congruent
D
mZJKL +mZILK = MZIMN + m2INM
E
ZJKL and ZJMN are both right angles

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?

The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. find the number.

One number is 4 less than 3 times a second number. if 3 more than two times the first number is decreased by 2 times the second number, the result is 11. use the substitution method. what is the first number?
