Answer:

49

Step-by-step explanation:

∆ABC~ ∆XYZ

AB= 11 that is half of XY = 22

therefore XZ/2 = AC (base) = 32/2 = 16

and YZ /2 = BC(hypotenuse) = 44/2 = 22

(a= 11, b= 16, c= 22)

perimeter of a triangle

P = a+b+c

P= 11+16+22= 49

Explain why you cannot factor the trinomial x(to the power of 2)−12x+6
Vladimir [108]

Answer:

See below

Step-by-step explanation:

You cannot find two whole number integers that give a sum of -12 and a product of 6.

-1 + -11 = -12, but (-1)(-11) = 11, which isn't 6

-2 + -10 = -12, but (-2)(-10) = 20, which isn't 6

...and so on...

WILL GIVE BRAINIEST ANSWER!!!Which lines are parallel to the graph of 4x – y = 6? Check all that apply.
kondaur [170]
If it is parallel, it means the slope is the same. We can convert 4x-y=6 into 4x-6=y after we isolate the x. We can also convert these other equations into slope intercept form. The answers are C, D, and F.

Determine the point estimate of the population proportion and the margin of error for the following confidence interval.Lower bo
Kamila [148]

Answer: The point estimate of the population proportion is . 485.​

The margin of error is 0.273.​

Step-by-step explanation:

Confidence interval for population proportion(p):

sample proportion ± Margin of error

Given:  Lower bound of confidence interval  = 0.212

Upper bound = 0.758

⇒sample proportion - Margin of error=0.212  (i)

sample proportion + Margin of error= 0.758  (ii)

Adding (i) and (ii) , we get

2(sample proportion) =0.970

⇒ sample proportion = 0.970÷2= 0.485

Since sample proportion is the point estimate of the population proportion.

So, the point estimate of the population proportion=  0.485

Now put sample proportion =0.485 in (ii), we get

0.485+ Margin of error= 0.758

⇒  Margin of error= 0.758 - 0.485 =0.273

i.e. The margin of error is 0.273.​

Whats going on in this attachment help thanks xD
rodikova [14]

Ratio remains same

\\ \rm\Rrightarrow \dfrac{4}{6x-3}=\dfrac{3}{2}

\\ \rm\Rrightarrow 8=3(6x-3)

\\ \rm\Rrightarrow 8=18x-9

\\ \rm\Rrightarrow 18x=17

\\ \rm\Rrightarrow x=17/18
