Answer:

.037 feet

Step-by-step explanation:

perimeter = the sum of all four sides so

perimeter = (4x-9.5) + (9.5x + 10) + (4x - 9.5) + (9.5x + 10) = 27x = 1

therefore x = 1/27 = .037 feet

Answer:

0.037 ft

Step-by-step explanation:

Perimeter is the distance around a two-dimensional shape. We add the side lengths to find the perimeter of regular polygons.

P = (4x - 9.5) + (9.5x + 10) + (4x - 9.5) + (9.5x + 10) = 27x = 1

x = 1/27 = 0.037 ft

The Wanting Recognition (WR) Scale provides a quantitative measure of a person's level of need for approval and sensitivity to s

levacccp [35]

Answer:

99% of the confidence level of the mean WR score for all convicted drug dealers

(37.4544, 40.5456)

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 100

Given that the mean of the sample(x⁻) = 39

Given a standard deviation of the sample (σ) = 6

Level of significance = 0.01 or 99%

Step(ii):-

99% of the confidence level of the mean WR score for all convicted drug dealers

$(x^{-} - Z_{0.01} \frac{S.D}{\sqrt{n} } ,x^{-} + Z_{0.01} \frac{S.D}{\sqrt{n} })$

$(39 -2.576 \frac{6}{\sqrt{100} } ,39 + 2.576 \frac{6}{\sqrt{100} })$

(39 - 1.5456 , 39+1.5456)

(37.4544, 40.5456)

Final answer:-

99% of the confidence level of the mean WR score for all convicted drug dealers

(37.4544, 40.5456)

A circle has a central angle of 6 radians that intersects an arc of length 14 in. Which equation finds the length of the radius,

xz_007 [3.2K]

C=2pir

arclength/circumference=centralangle/2piradians

14/2pir=6/2pi
7/pir=3/pi
times pir both sides
7=3r
divide by 3 both sides
7/3=r

well,
um
the answer is B
