Help!!!!!!!!!!!!!!!!!!!!
lapo4ka [179]
Well...   the segment FG = 4x + 3, the segment GH = 7x - 12, now, the
 
segment FH = FG + GH, those two fellows added up, and we know that FG and GH are both equal halves because G is the midpoint.

thus, FG = GH
or

\bf 4x+3=7x-12\implies 3+12=7x-4x\implies 15=3x&#10;\\\\\\&#10;\cfrac{15}{3}=x\implies \boxed{5=x}\\\\&#10;-------------------------------\\\\&#10;thus\qquad &#10;\begin{cases}&#10;\overline{FG}=4x+3\\&#10;4(5)+3\\&#10;23\\&#10;------\\&#10;\overline{GH}=7x-12\\&#10;7(5)-12\\&#10;23&#10;\end{cases}\impliedby equal\ halves&#10;\\\\\\&#10;\overline{FH}=23+23\implies \overline{FH}=46\implies 6y-2=46&#10;\\\\\\&#10;6y=46+2\implies y=\cfrac{48}{6}

and fairly sure, you know how much that is.

The length of a rectangular park is four timesfour times its width. The park is surrounded by a 33​-foot-wide path. Let x denote
tiny-mole [99]

Answer:

A(x) = 4x^2 + 330x + 4356

Step-by-step explanation:

width of park: x

length of park: 4x

width + path width = x + 66

length + path width = 4x + 66

area = (x + 66)(4x + 66)

area = 4x^2 + 66x + 264x + 4356

area = 4x^2 + 330x + 4356

A(x) = 4x^2 + 330x + 4356

f a sampling distribution is created using samples of the amounts of weight lost by 51 people on this diet, what would be the st
galina1969 [7]

This question is incomplete, the complete question is;

A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 24.6 pounds and a standard deviation of 8.0 pounds.

Step 2 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 51 people on this diet, what would be the standard deviation of the sampling distribution of sample means? Round to two decimal places, if necessary.

Answer:

the standard deviation of the sampling distribution of sample means is 1.12

Step-by-step explanation:

Given the data in the question,

population mean; μ = 24.6  pounds

Population standard deviation; σ = 8.0 pounds

sample size; n = 51

Now determine the standard deviation of the sampling distribution of sample means.

standard deviation of the sampling distribution of sample means is simply

⇒ population standard deviation / √sample size

= 8.0 / √51

= 8.0 / 7.141428

= 1.120224 ≈ 1.12

Therefore, the standard deviation of the sampling distribution of sample means is 1.12
