Answer:

<MTE =90°

the inscribed angle from the diameter is 90°

in triangle MTE

MT=8 unit

TE=6unit

by using Pythagoras law

D=ME=√(8²+6²)=10 unit

radius =D/2=10/2=5unit

circumference of circle D=2πr=2π×5=10π or31.4unit

Answer:

10π

Step-by-step explanation:

Since ME is the diameter of the circle,

angle MTE = 90° (∠ in semicircle)

By pyth. theorem we can obtain,

ME = √8² + 6²

ME = 10

The diameter of the circle is 10

The circumference of circle D is 10π

Jai Narayan sells two radio sets for 2288 each.

san4es73 [151]

Answer:

Step-by-step explanation:

S.P of each radio=$ 2288

Total S.P= $2\times 2288=$ $4576

Gain=10%

Lose=10%

C.P= $\frac{S.P\times 100}{100+gain(in\;percent)}$

C.P= $\frac{S.P\times 100}{100-loss(in\;percent)}$

By using the formula

C.P of one radio= $\frac{2288\times 100}{110}=$ $2080

C.P of another radio= $\frac{2288\times 100}{100-10}$ =$2542.2

Total C.P of two radios=2080+2542.2=$4622.2

Total C.P >Total S.P

Loss=S.P-C.P

Loss=4622.2-4576=$46.2

Loss%= $\frac{Loss}{C.P}\times 100$

Loss %= $\frac{46.2}{4622.2}\times 100=$ 1%

Hence, his loss 1%

Answer:

REQUIRED TEST STATICS IS 35.19

Step-by-step explanation:

total size of sample = 10,000

men women

voted 2777 3466

did not vote 1444 2313

By chi square test we can find the relationship between gender and participation in the election

$X^2 = \frac{ N(ad-bc)^2}{(a+c)(b+d)+(a+b)(c+d)}$

where

a represent = 2777, b = 3466, c= 1444, d = 2313, N = 10000

Putting values to get chis square statics

$X^2 = \frac{ 10000(2777*2313-3466*1444)^2}{(2777+1444)(3466+2313)+(2777+3466)(1444+2313)}$

$X^2 = = 35.159$
