Answer:

The median is 3

Step-by-step explanation:

Because the median is the middle number of an list of numbers. Sometimes the median can have two numbers but in this case there is only one

Answer:

Step-by-step explain:

when you think of median, think of middle, the middle of those numbers is 3. When you have a even number of values for example i have 6 values and i have to find the median. I would look at the 2 middle numbers and come up with my median.

Write an equation for the nth term of the arithmetic sequence. Then find a50. −29, −12, 5, 22, . . . an = a50 =

DIA [1.3K]

Answer:

$\bold{a_n=17n+46}\\\\\bold{a_{50}=896}$

Step-by-step explanation:

−29, −12, 5, 22, ...

-12-(-29) = 17; 5-(-12) = 17; 22-5 = 17 ⇒ d = 17

first term: a = -29

difference: d = 17

so the formula:

$a_n=a+d(n-1)\\\\a_n=-29+17(n-1)\\\\a_n =-29+17n-17\\\\\underline{a_n=17n+46}$

and:

$a_{50}=17\cdot50+46=850+46 = 896$

If logx (8x-3) -logx 4=2, the value of x is

Vaselesa [24]

Answer:

x = 1/2 and 3/2

Step-by-step explanation:

The given equation is logₓ (8x-3) - logₓ 4 = 2

Then we have to determine the value of x.

logₓ $[\frac{(8x-3)}{4}]$ = 2 [ since log a - log b = log $(\frac{a}{b})$ ]

Now $x^{2}=\frac{(8x-3)}{4}$ [if $log_{a}$ b = c then $a^{c}$ = b]

4x² = 8x -3

4x² - 8x + 3 = 0

(2x)² - 2(4x) + (4-4) + 3 = 0

[(2x)² - 2 (4x) + 4 ] - 1 = 0

(2x - 2)² = 1

(2x - 2)² = ± 1 ⇒

2x - 2 = 1 and 2x - 2 = -1

x = 3/2 2x = 1

x = 1/2

Therefore, x = 1/2 and 3/2 are the answers.
