Find a formula for the nth term of the geometric sequence. Assume the n begins with 1. a1=18, a2=9​
LUCKY_DIMON [66]

Answer:

Option E

Step-by-step explanation:

Explicit formula of a geometric sequence is,

T_n=a_1(r)^{n-1}

Here, a_1= First term

r= common ratio

n= number of terms

If, a_1=18 and a_2=9

Common ratio of the sequence r=\frac{a_2}{a_1}

r=\frac{9}{18}

r=\frac{1}{2}

By substituting these values in the formula,

T_n=18(\frac{1}{2} )^{n-1}

Therefore, Option E is the answer.

What’s 40 41 42 43 44 45 46 47 48 49 50 IQR pls fast!!!!!
aliina [53]

Answer:

IQR = 6

Step-by-step explanation:

Given:

The given set of data is:

40 41 42 43 44 45 46 47 48 49 50

Number of terms, n=11

Therefore, the median is given as (\frac{n+1}{2})^{th} term which is the sixth term. Median = 45

(40 41 42 43 44) <u>45</u> (46 47 48 49 50 )

Now, we find the median of the lower half (Q_1) and upper half (Q_3)of the data that are before and after the median.

The lower half of the data has the values 40 41 <u>42</u> 43 44.

Number of terms are 5. So, median is the third term which is, Q_1=42

The upper half of the data has the values 46 47 <u>48</u> 49 50.

Number of terms are 5. So, median is the third term which is, Q_3=48

Now, IQR is given as the difference of upper half median and lower half median.

IQR=Q_3-Q_1\\IQR=48-42=6

74/360 in simplest form​
Umnica [9.8K]

Answer:

37/180

Step-by-step explanation:

Reduce this fraction by dividing both sides by 2.  We get 37/180, which cannot be reduced further; 37 and 180 have no common factor.
