Find the value of x. (7x - 1)º (6x - 1)º

Mathematics
1 answer:
dangina [55]3 years ago
6 0

Answer:

Step-by-step explanation:

7x - 1 + 6x - 1 = 180

13x - 2 = 180

13x = 182

x = 14

7(14) - 1 = 98 - 1= 97

6(14) - 1 = 84 - 1 = 83

Answer:

13.04 cm^2

Step-by-step explanation:

Larger Circle diameter is 12.5 cm and the smaller is 3.5 cm

The Area of a circle is A = πr^2 = πd^2/4

Larger Circle divide the diameter by 2 = 6.25 cm

Smaller Circle dive the diameter by 2 = 1.75 cm

Using above formula  A =  122.71846303085 cm^2 &  

Finally we deduct the smaller Area from the larger Area

A = 9.6211275016187 cm^2 - 9.6211275016187 cm^2

122.71846303085 cm^2 - 9.6211275016187 cm^2 =

113.0973355292 cm^2 thus 13.04 is your answer since I used the

π = 3.1415926535898

A = area

π = pi = 3.1415926535898

A fair six-sided die, with sides numbered 1 through 6, will be rolled a total of 15 times. Let x¯1 represent the average of the
Anna35 [415]

Answer:

option B

Step-by-step explanation:

P(x =x) [{\frac{1}{6} ;x =1,2,3...6]

E (x) = \frac{6+1}{2} =\frac{7}{2} =3.5\\\\E(x)=3.5

Given random experiment of tossing of 6 sided dice is follow above distribution

Therefore, suppose x₁, x₂ ...x₁₀ are 10 independent and indentical random variable which represent first 10 rolls

Average of first 10 rows equals

\bar x_1 =\frac{ \sum ^{10}_{i=1}xi}{10}

E(\bar x_1)=\frac{ \sum ^{10}_{i=1}E(x_1)}{10} \\\\=\frac{10(3.5)}{10} \\\\=3.5\\\\E(\bar x_1) = 3.5----(1)

now suppose ,

x₁₁,x₁₂, ...x₁₅ are 5 independent and identical random variable which represent last 5 roll

average of last 5 roll is

E(\bar x_2)= \frac{ \sum ^{5}_{i=1}xi}{5} \\\\= \frac{5 \times(3.5)}{5} \\\\=3.5

Therefore,\bar x_1 - \bar x_2

3.5 - 3.5 = 0
