Answer: 0.28

Step-by-step explanation:

Binomial probability formula :

P(X=x)=\ ^nC_xp^x(1-p)^x , where  x = Number of success , n= sample size , p= probability of success for each trial.

Let x = Number of hens lay eggs.

then, p=  0.80

n= 12

For x=10

P(x=10)=\ ^{12}C_{10}(0.80)^{10}(0.20)^{2}\\\\=\dfrac{12!}{10!2!}\times 0.1073741824\times 0.04\\\\\approx0.28

Hence, the required probability = 0.28

A triangle with which angle types could be constructed?
kifflom [539]

Answer:

B is the answer.

Step-by-step explanation:

*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^

Triangles cannot have two 90 degrees because that would add up to 180 and triangles need 3 angles to add to 180

You can't have an obtuse angle and a right angle. say the obtuse angle was 110, and a right angle is 90. 110 + 90 is more than 180.

Two obtuse angles would be more than 180.

This leaves us with B being correct, because you can have an obtuse angle and an acute angle, and it can be less than 180 degrees.

Tju [1.3M]

Answer:

6 at tens place is 10 times 6 at unit place.

Step-by-step explanation:

We are given that  a number

50,866

Underlined digits are 66.

We  have to find the relationship between underlined digits.

Unit place =6

Tens place=

Tens place value=6\times 10=60

Unit pace value=6

6 at tens place is 10 times 6 at unit place.

This is required relation relation between underlined digits 66.

xz_007 [3.2K]
B) Ana is correct because 2 + 10 is greater than 10

if it were less than 10 then the last length would not be long enough to reach to the other side
