Determine if triangle OPQ and triangle RST are or are not similar, and, if they are, state which triangle similarity shortcut (A
murzikaleks [220]

Answer:

SAS Similarity

Step-by-step explanation:

ΔOPQ similar to ΔRST

∠Q  = ∠T

OQ : RT = 28 : 84 = 1 : 3

QP : TS  = 16 : 48 = 1 : 3

The measures of two sides of ΔOPQ are proportional to the measure of two side of ΔRST and their included angles are congruent.  The triangles are similar by SAS Similarity.

A meteorologist in denver recorded y = the number of days of rain during a 30-day period. does y have a binomial distribution? i
olga_2 [115]

Solution: Yes, the random variable y will have a binomial distribution. Because there are two possible outcomes 1. number of days of rain and 2. number of days of no rain.

The parameters of binomial distribution are n and p

The parameter n is given as the number of day's under consideration.

\therefore n=30

The parameter p is not given, but it can be estimated by number of days it rained divided by the total number of days under consideration.

\therefore p=\frac{y}{n} =\frac{y}{30}

I picked random so please help me
Anna [14]

9514 1404 393

Answer:

  A.  6, 24, 96, 384

Step-by-step explanation:

The recursive formula tells you that the next number in sequence is 4 times the previous one.

For first term 6, the second term is 4·6 = 24.

For 2nd term 24, the third term is 4·24 = 96.

For 3rd term 96, the fourth term is 4·96 = 384.

The first four terms of the sequence are ...

  6, 24, 96, 384

__

You don't even need to figure all four terms. You know immediately which sequence is correct once you have found ...

  G_2=4*G_1=4*6=24
