3<y<7 y is greater than 3 but less than 7

First the data must be ordered:
3, 4, 5, 6, 7.
The range is 7 - 3 = 4.
The LQ is (3 + 4)/2 = 3.5.
The UQ is (6 + 7)/2 = 6.5.
Therefore the IQR is 6.5 - 3.5 = 3.

Consider a sequence given by the formula f(n) = 1 / 3 ^ n−1 starting with n = 1. Generate the first 5 terms of the
denpristay [2]

Answer:

Step-by-step explanation:

According to the formula we need to start from n = 1. So the first 5 terms of the sequence, will have the following values of n: 1,2,3,4,5

Now, we need to replace the values of n into the formula to get all the terms.

f(1) = 1/3 ^ 1-1 = 1/3^0 = 1.

This is because any number elevated to zero is always the unit, in this case, 1.

f(2) = 1/3 ^2-1 = 1/3 ^1 = 1/3

This, because any number elevated to 1, is always the same initial number.

f(3) = 1/3 ^3-1 = 1/3 ^2 = 1/9.

Because when the exponent is elevating a fraction number, the power goes to both numbers (numerator and denominator)

f(4) = 1/3 ^4-1 = 1/3 ^3 = 1/27.

f(5) = 1/3 ^5-1 = 1/3 ^4 = 1/81.

What are the numerical measures of the angles?
vredina [299]
ANSWER

The sum of m∠DEA and m∠AEB is 180°.

Reason: The sum of angles on a straight line is always 180°.

(x + 25)+(9x + 10)=180 \degree

Group like terms to get,

x+9x=180-25-10

Simplify, and get,

10x = 145

Divide both sides by 10 to get,

x = 14.5

We substitute this value to get the required angles.

m \: ∠DEA=x+25

m \: ∠DEA = 14.5 + 25 = 39.5 \degree

m\:∠AEB=9x+ 10

m\:∠AEB = 9(14.5) + 10

m\: ∠AEB=130.5 + 10 = 140.5 \degree
