The following sequence is geometric. What is the next term?
Kruka [31]
A geometric sequence is one where you multiply each number in the sequence by the same number. Here, obviously the number which you multiply by is 3, because 12 * 3 = 36, 36 * 3 = 108, 108 * 3 = 324, and in order to finish the sequence, you multiply 324 by 3 and get 972.
The correct answer is 972.

Anton [14]

Answer: (336.49,\ 355.51)

Step-by-step explanation:

The confidence interval for population mean is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n= 314 , which is a large sample , so we apply z-test .

Sample mean : \overline{x}=346

Standard deviation : \sigma= 86

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

Now, a confidence interval at the 95% level of confidence will be :-

346\pm(1.96)\dfrac{86}{\sqrt{314}}\\\\\approx346\pm9.51\\\\=(346-9.51,\ 346+9.51)\\\\=(336.49,\ 355.51)

The manufacturers of cans of salted moxies nuts state that the ratio of peanuts to other is 5 to 3. If 360 peanuts are in a can,
Rina8888 [55]

Answer:216

Step-by-step explanation:

We let x to represent the number of other nuts

Peanut : other

5 : 3

360 : X

Then we cross multiply

5 × x = 360 × 3

5X = 1080

Divide bothside by 5

5X/5 = 1080/5

X = 216

Therefore the number of other nuts in the can is 216.

What expression is equivalent to the area of metal sheet required to make this square-shaped traffic sign?
AveGali [126]

Answer: \text{Area of the square shaped traffic sign }=16x^2+9+24x

Step-by-step explanation:

Given: The side of the square shaped traffic sign = 4x+3

We know that the area of square is given by:-

Area= side^2

Therefore, the area of the side of the square shaped field is given by:-

Area=(4x+3)^2

We know that , (a+b)^2=a^2+b^2+2ab

Therefore,

(4x+3)^2=(4x)^2+(3)^2+2(4x)(3)\\=16x^2+9+24x

Hence, \text{Area of the square shaped traffic sign }=16x^2+9+24x
