Answer:

\dfrac{4X}{3} \:Units

Step-by-step explanation:

Quadrilaterals KMPT is dilated by a scale factor of 3/4 to create a quadrilateral.

Since KMPT is dilated by a scale factor of 3/4

\text{Perimeter of the dilated Quadrilateral=}\dfrac{3}{4} X $ Perimeter of quadrilateral KMPT

Given that the perimeter of the dilated quadrilateral is X units.

Therefore:

X \:Units=\dfrac{3}{4} X $ Perimeter of quadrilateral KMPT\\Perimeter of quadrilateral KMPT =\dfrac{4X}{3} \:Units

Scores of an IQ test have a​ bell-shaped distribution with a mean of 100 and a standard deviation of 13. Use the empirical rule
Yuri [45]

Answer:

(a) 68% of people has an IQ score between 87 and 113​.

(b) 5% of people has an IQ score less than 74 or greater than 126.

(c) 0.15% of people has an IQ score greater than 139​.

Step-by-step explanation:

Given information:Scores of an IQ test have a​ bell-shaped distribution,

mean = 100

standard deviation = 13

According to the empirical rule

68% data lies between \overline{x}-\sigma and \overline{x}+\sigma.

95% data lies between \overline{x}-2\sigma and \overline{x}+2\sigma.

99.7% data lies between \overline{x}-3\sigma and \overline{x}+3\sigma.

(a)

\overline{x}-\sigma=100-13=87

\overline{x}+\sigma=100+13=113

[\overline{x}-\sigma,\overline{x}+\sigma]=[87,113]

Using empirical rule we can say that 68% of people has an IQ score between 87 and 113​.

(b)

\overline{x}-2\sigma=100-2(13)=74

\overline{x}+2\sigma=100+2(13)=126

[\overline{x}-2\sigma,\overline{x}+2\sigma]=[74,126]

Using empirical rule we can say that 95% of people has an IQ score between 74 and 126​.

The percentage of people has an IQ score less than 74 or greater than 126 is

P = 1- percent of people has an IQ score between 74 and 126​.

P = 1- 95%

P = 5%

Therefore 5% of people has an IQ score less than 74 or greater than 126.

(c)

\overline{x}-3\sigma=100-3(13)=61

\overline{x}+3\sigma=100+3(13)=139

[\overline{x}-3\sigma,\overline{x}+3\sigma]=[61,139]

Using empirical rule we can say that 99.7% of people has an IQ score between 61 and 139​.

The percentage of people has an IQ score less than 61 or greater than 139 is

P = 1- percent of people has an IQ score between 61 and 139​.

P = 1- 99.7%

P = 0.3%

The percentage of people has an IQ score greater than 139​ is

P=\frac{1}{2}(0.3\%)=0.15\%

Therefore 0.15% of people has an IQ score greater than 139​.

the length of a rectangle is 2 times in width if the perimeter of the rectangle is 36 in find its length and width​
Basile [38]

Answer:

Length=12 inches Width=6 inches

Step-by-step explanation:

X can stand for the width. 2x can stand for the length since it is twice the width. The perimeter would then equal 6x. 6x is equal to 36. Divide by 6 to isolate x. X equals 6 inches. So twice the width would be 12 inches.

A crane is lowering a concrete block from a height of 270 feet above the ground at a constant rate of 2.5 feet per second. Which
iogann1982 [59]

The function would be h = 270 - 2.5s, where h is the height (in feet) and s it the time (in seconds) that has passed.

The 270 represents the initial value, which is given. We are told that the initial height of the block is 270 feet.

2.5s represents the feet that it has descended. We know the block is lowered at a rate of 2.5 feet per second. Multiplying this by s, the time, will give us how much it has descended.

While preparing his budget sheet richard Smith noticed that his annual expenses were 18800 while his monthly living expenses wer
PIT_PIT [208]

Answer:

Monthly Living Expense = 2375

Monthly Fixed Expense = 1975

Step-by-step explanation:

Let monthly living expense be "x"

and monthly fixed expense be "y"

<u>"monthly living expenses were 400 more than his monthly fixed expenses":</u>

x = 400 + y

<u>"Richard total monthly expenses were 4350":</u>

x + y = 4350

Putting Equation 1 in Equation 2:

(400 + y) + y = 4350

400 + 2y = 4350

2y = 3950

y = 1975

Now, x = 400 + y = 400 + 1975 = 2375
