Answer:

119.2

Step-by-step explanation:

Given the following :

Mean (m) = 100 years

Standard deviation (sd) = 15 years

closest to the age of a Galápagos Islands giant tortoise at the 90th percentile of the

distribution?

Obtain the Zscore for 90th percentile (0.90) on the z table = 1.28

Zscore = (X - mean) / standard deviation

1.28 = (X - 100) / 15

1.28 × 15 = X - 100

19.2 = X - 100

19.2 + 100 = X

X = 119.2

Answer:

x = 9.5

Step-by-step explanation:

Given

$\frac{4x-6}{4}$ = $\frac{2x+5}{3}$ ( cross- multiply )

3(4x - 6) = 4(2x + 5) ← distribute parenthesis on both sides

12x - 18 = 8x + 20 ( subtract 8x from both sides )

4x - 18 = 20 ( add 18 to both sides )

4x = 38 ( divide both sides by 4 )

x = $\frac{38}{4}$ = 9.5

A recursive rule for an arithmetic sequence is a₁=4;a_n=a_(n−1)−3 .

steposvetlana [31]

The explicit formula of the arithmetic sequence:

$a_n=a_1+(n-1)d$

d - common difference

We have the recursive formula of an arithmetic sequence:

$\left\{\begin{array}{ccc}a_1=4\\a_n=a_{n-1}-3\end{array}\right$

Therefore we have:

$a_1=4,\ d=-3$

Substitute:

$a_n=4+(n-1)(-3)=4-3n+3=7-3n$

<h3>Answer: aₙ = 7 - 3n</h3>
