Answer:

Figure: Amount of tiles:

1 5

2 8

3 11

4 14

5 17

6 20

7 23

8 26

9 29

10 32

11 35

12 38

13 41

The sequence/pattern is +3 tiles.

So Figure 13 will have 41 tiles.

I hope this helps!

Three randomly selected households are surveyed. /The numbers of people in the households are 1, 3, and 8. Assume that samples o

inn [45]

The question is asking to find the variance for the said samples in the problem ans use the sample data to determine each variance, and base on my further computation and further calculation, I would say that the answer would be the following:
#1. 3.3 -> 1 and 3 -> 2/9
#2. 1-> 0->3/9
#3. 6.3 - > 8 and 3-> 2/9
#4 49-> 1 and 8-> 2/9

3(x + 4) = 27 what is x

Alla [95]

Answer:

x = 5

Step-by-step explanation:

This is a simple equation if you look at it right and don't get scared by the "x."

All we need to do is figure out what times 3 = 27. We can do this easily by diving 27 by 3.

27 ÷ 3 = 9

Since our "equation" is 3(x + 4) = 27 we know whatever is in the parenthesis () has to equal to 9. We already get 4 so:

5 + 4 = 9.

3 times 9 = 27.

5 is your answer.

<u>Hope this helps and have a nice day!</u>

PS if you could mark brainliest that'd be great! I'm very close the "expert" rank. Haha, sorry I usually don't ask.

Answer: OPTION B.

Step-by-step explanation:

We have the following functions f(x) and g(x):

$f(x)=x^2-2x-8\\\\g(x)=\frac{1}{4}x-1$

In order to find for which values of "x" $f(x)=g(x)$ , we can check each option given:

<u>OPTION A</u>

Substitute $x=-1.75$ into the function f(x) and evaluate:

$f(-1.75)=(-1.75)^2-2(-1.75)-8=-1.4375$

Substitute $x=-1.75$ into the function g(x) and evaluate:

$g(-1.75)=\frac{1}{4}(-1.75)-1=-1.4375$

Substitute $x=-1.438$ into the function f(x) and evaluate:

$f(-1.438)=(-1.438)^2-2(-1.438)-8=-3.0561$

Substitute $x=-1.438$ into the function g(x) and evaluate:

$g(-1.438)=\frac{1}{4}(-1.438)-1=-1.3595$

This is not the correct option.

<u>OPTION B</u>

We already know that:

$f(-1.75)=-1.4375$

$g(-1.75)=-1.4375$

Substitute $x=4$ into the function f(x) and evaluate:

$f(4)=(4)^2-2(4)-8=0$

Substitute $x=4$ into the function g(x) and evaluate:

$g(4)=\frac{1}{4}(4)-1=0$

<em> This is the correct option.</em>

<u>OPTION C</u>

We already know that:

$f(-1.438)=-3.0561$

$g(-1.438)=-1.3595$

Therefore, this is not the correct option.

<u>OPTION D</u>

We already know that:

$f(4)=0$

$g(4)=0$

Substitute $x=0$ into the function f(x) and evaluate:

$f(0)=(0)^2-2(0)-8=-8$

Substitute $x=0$ into the function g(x) and evaluate:

$g(0)=\frac{1}{4}(0)-1=-1$

This is not the correct option.
