Answer:
The 53rd term of this arithmetic sequence is -805.
Step-by-step explanation:
The general rule of an arithmetic sequence is the following:
In which d is the common diference between each term, that is, 
.
To find the nth term of the sequence, this equation can be written as:
27,11, -5
So ![a_{1} = 27, a_{2} - a_{1} = 11 - 27 = -16[/tex[tex]a_{n} = a_{1} + (n-1)d](https://tex.z-dn.net/?f=a_%7B1%7D%20%3D%2027%2C%20a_%7B2%7D%20-%20a_%7B1%7D%20%3D%2011%20-%2027%20%3D%20-16%5B%2Ftex%3C%2Fp%3E%3Cp%3E%5Btex%5Da_%7Bn%7D%20%3D%20a_%7B1%7D%20%2B%20%28n-1%29d)
The 53rd term of this arithmetic sequence is -805.
Answer:
For f(x) = 2x + 3 and g(x) = -x 2 + 1, find the composite function defined by (f o g)(x)
(f o g)(x) = f(g(x))
= 2 (g(x)) + 3
= 2( -x 2 + 1 ) + 3
= - 2 x 2 + 5 Given f(2) = 3, g(3) = 2, f(3) = 4 and g(2) = 5, evaluate (f o g)(3)

Answer:
Two-tailed test.
Step-by-step explanation:
There are two types of tests:
One-tailed tests and two-tailed tests.
When we only test if the mean is less or more than a value, we have a one-tailed test.
When we test if the mean is different from a value, we have a two-tailed test.
If you were to conduct a test to determine whether there is evidence that the proportion is different from 0.30, which test would you use?
Test if it is different, so a two-tailed test.
Answer:
Step-by-step explanation:
Deal #1: One pizza= $8.99
Deal #2: One pizza= $6.00
Deal #1: Two pizzas= $13.99
Deal #2: Two pizzas= $12.00
Deal #1: Three pizzas= $18.99
Deal #2: Three pizzas= $18.00
Deal #1: Four pizzas= $23.99
Deal #2: Four pizzas= $24.00
Therefore, after FOUR pizzas, deal #1 becomes a better deal.
Tip: Practice some math. You should be able to answer something like this within two minutes MAXIMUM.
Answer:
0,252
Step-by-step explanation:
De la pregunta,
1 minuto = 0.08
3,15 minutos = x
Cruz multiplicar
x = 3,15 × 0,08
x = 0,252
Por tanto, por su última llamada que duró 3,15 minutos, Laura estaría pagando 0,252
