Answer:

Alright so the answer is B but I'll explain why because im nice ig.

Step-by-step explanation:

So lets do some calcumalations.

We'll use 1 as n and should get an output of 3 to check these formulas. Since 1 is the first term and 3 is the first term value makes sense alright.

So 9^1-1 is 0 and any number to the 0 power is 1 so that wont work.

3(4)^1-1 = 3(1); that's the answer

4^1-1 = 1, + 3 = 4 so that wont work either

I hope this helps ya have a great afternoon

Jeanette obtained 32% for her statistics test, which was out of a total of 300 marks. How much should she score in the computer

Andre45 [30]

Using weighted average, it is found that she should score 67% on the computer science test.

The weighted average is given by <u>each proportion multiplied by it's score</u>.

In this problem, the proportions and scores are given by:

Proportion of 32% = 0.32 for a score of 300.
Proportion of x for a score of 200.
Proportion of 46% = 0.46 for a score of 300 + 200 = 500.

Then

$0.32(300) + 200x = 0.46(500)$

$200x = 0.46(500) - 0.32(300)$

$200x = 134$

$x = \frac{134}{200}$

$x = 0.67$

She should score 67% on the computer science test.

$\qquad \qquad \bf \huge\star \: \: \large{ \underline{Answer} } \huge \: \: \star$

Angle x = 29°

$\textsf{ \underline{\underline{Steps to solve the problem} }:}$

$\sf \: \angle x + 109 + 42 = 180$

( makes co - interior angles, since the two lines are parallel )

$\sf \: \angle \: x + 151 = 180$

$\sf \: \angle x =18 0 - 151$

$\sf \: \angle x = 29 \degree$

$\qquad \large \sf {Conclusion} :$

x = 29°
