54; 18; 76; 42; 76; and 46 mean: median: mode:

1 answer:

4 0

To work out the mean, add them all up and divide by however many values there are:

(18+54+42+(76x2)+46) / 6 = 52

To work out the median, order them from largest to smallest or vice versa and find the middlest value.

18, 42, 46, 54, 76 ,76

(46 + 54) / 2 = 50

The mode is the most frequently occurring number, so it would be 76.

In the arithmetic sequence t1, t2, t3, . . . , tn, . . . , t1 = 23 and tn = tn – 1 – 3 for each n > 1. What is the value of n

elena-14-01-66 [18.8K]

An arithmetic sequence is a string of numbers that is produced by repeatedly applying a certain arithmetic operation, in this case the string of numbers $t_{1} , t_{2}, t_{3}, ..., t_{n}, ...$ is thus determined, the first term $t_{1}$ is equivalent to number 23 and each next term, $t_{n}$ with $n>1$ (i.e. $t_{2} , t_{3}, t_{4}, ...$ ) is calculated using the given formula $t_{n}= t_{n-1} -3$ , so the next term in the sequence, $t_{2}$ will be:

$t_{2}= t_{1}-3\\ t_{2}= 23-3 = 20$

in the same way the following terms are calculated

$t_{3} = t_{2}-3\\t_{3} = 20-3 = 17\\t_{4} = t_{3}-3\\t_{4} = 17-3 = 14\\...\\t_{9} = t_{8}-3\\t_{9} = 2-3 = -1\\t_{10} = t_{9}-3\\t_{10} = -1-3 = -4$

Another way to achieve this is to use the formula to calculate the terms $t_{n}$ , note that:

$t_{2} = t_{1}-3\\t_{3} = t_{2}-3 = (t_{1}-3) -3 = t_{1}-6\\t_{4} = t_{3}-3 = (t_{1}-6) -3 = t_{1}-9=t_{1}-3(3)\\t_{5} = t_{4}-3 = (t_{1}-9) -3 = t_{1}-12=t_{1}-3(4)$

So, as you see each tn becomes $t_{1}$ minus a multiple of -3, or what is the same:

$t_{n}= t_{1} -3 (n-1)\\t_{n}= 23-3 (n-1)$

Replacing the desired value

$23-3 (n-1)=-4\\23 + 4 = 3 (n-1)\\27 = 3 (n-1)\\27/3 = (n-1)9 = n-1\\n = 10$

Answer

the value of n when $t_{n} =-4$ is $n=10$ , $t_{10}$

Having some trouble with this question, any help? A wire supporting a radio tower is secured to the ground 14 m from the base of

Lera25 [3.4K]

By using what we know about right triangles, we will see that the height is 11.7 m.

<h3>How to find the height of the tower?</h3>

We can view this as a right triangle, such that the wire is the hypotenuse of said triangle.

We know that the hypotenuse measures 14 m, and the angle between the ground and the wire si 57°. The height would be the opposite cathetus to that angle, so we can use the rule:

Sin(a) = (opposite cathetus)/hypotenuse

Replacing the values we get:

Sin(57°) = H/14m

Sin(57°)*14m = H = 11.7m

The height of the tower is 11.7 meters.
