WILL GIVE BRAINLIEST<br><br>solve for x : -4 = (2/3)x <br><br>show steps please

cupoosta [38]

<h2>Answer: x = -6</h2>

<h3>Step-by-step explanation:</h3>

To solve for x, we have to find a way to make x the subject of the equation (get x on one side and everything else on the other side)

since -4 = (2/3)x [mutiply both sides by 3]

⇒ -4 × 3 = 2x [divide both sides by 2]

⇒ (-12/2) = x [simplify by dividing -12 by 2]

∴ x = -6

Which value of b would make 16x²-bx + 25 a perfect square trinomial?

blondinia [14]

Answer:

b = 40 and -40

Step-by-step explanation:

General form of Perfect square trinomial is a 2 + 2 a b + b 2

Therefore from 16 x 2 − b x + 25 a 2 = √ 16 x 2 , b 2 = 25 , then a = ± 4 x , b = ± 5 take consideration a=4x and b=-5 (different sign), then − b x = 2 ( 4 x ) ( − 5 ) − b x = − 40 x b = 40

The perfect square is ( 4 x − 5 ) 2 = 16 x 2 − 40 x + 25 .

if we consider a=4x and b=5 (same sign), then − b x = 2 ( 4 x ) ( 5 ) − b x = 40 x b = − 40

The perfect square is ( 4 x + 5 ) 2 = 16 x 2 + 40 x + 25 .

The first solution ( 4 x − 5 ) 2 is the best solution after comparing the expression given. I hope this helps, xx .

A random sample of a specific brand of snack bar is tested for calorie count, with the following results: Assume the population

LenKa [72]

Answer:

The 95% confidence interval for the population mean (calorie count of the snacks bars) is (130.32, 161.68).

Step-by-step explanation:

<em>The question is incomplete:</em>

<em>"A random sample of a specific brand of snack bar is tested for calorie count, with the following results: </em><em>149, 145,140,160,149,153,131,134,153</em><em>. Assume the population standard deviation is </em><em>σ=24</em><em> and that the population is approximately normal. Construct a 95% confidence interval for the calorie count of the snack bars."</em>

We start by calculating the mean of the sample:

$M=\dfrac{1}{9}\sum_{i=1}^{9}(149+145+140+160+149+153+131+134+153)\\\\\\ M=\dfrac{1314}{9}=146$
