Use the given figure to find the length of FG
frutty [35]

Answer:

FG = 19

Step-by-step explanation:

The two sides of the triangle are equal since JG is a perpendicular bisector

FG = HG

5x-6 = 3x+4

Subtract 3x from each side

5x-3x -6 = 3x+4-3x

2x-6 =4

Add 6 to each side

2x-6+6 =4+6

2x = 10

Divide by 2

2x/2 = 10/2

x =5

We want to find FG

FG = 5x-6

FG = 5(5)-6

    = 25-6

    = 19

"A state legislator wishes to survey residents of her district to see what proportion of the registered voters are aware of her
aliya0001 [1]

Answer:

The correct answer to the following question will be "384".

Step-by-step explanation:

We are having,

P(-0.05

On solving, we get

⇒  P(\frac{-0.05}{\sqrt{\frac{pq}{n}}}

⇒  \frac{0.05}{\sqrt{\frac{p(1-p)}{n}}} =1.96

On applying cross-multiplication, we get

⇒  0.05^2=1.96^2\times \frac{P(1-p)}{n}

⇒  0.05^2n=1.96^2-1.96^2p^2

⇒  1.96^2p^2-1.96^2p+0.05^2n=0...(equation 1)

When "p" seems to be the population proportion, (equation 1) approach, which is special

∴ b^2-4ac=0

On putting the values in the above expression, we get

⇒  (1.96)^4-4\times 0.05^2\times 1.96^2n=0

⇒  1.98^2-4\times 0.05^2n=0

⇒  n=\frac{1.96^2}{4\times 0.05^2}

⇒  n=384.16=384

Log3(2x-1)=3 help me out:(
aleksley [76]

Answer:

x = 2.

Step-by-step explanation:

(Brainliest?)

So log3(2x-1)+log3(x+7)=3 = log3(3^3) So (2x- 1)(x+7) = 27..... 2x^2+13x - 34 =0 (2x+17)(x - 2) = 0 ..so x = 2 or - 17/2. The solution x = - 17/2 is rejected since we cannot have log 3(2*- 17/2 - 1),a negative number. So the answer is x = 2.
