-6
Step-by-step explanation:
You can solve all math problems via Photo math application, you can download it from the store for free, it is easy to write the question via the camera and quickly display the final result with the solution steps.
Can you make the answer clearer. I would be glad to help you. I just don't understand where it says "the sum of three numbers is 16 the sum of twice the first number"
Answer:
The probability that the number of correct answers is 4 is 0.2461.
Step-by-step explanation:
Let <em>X</em> = number of correct answers.
The probability that an answer is correct is,P (X) = <em>p</em> = 0.50.
The total number of questions is, <em>n</em> = 9.
The event of an answer being correct is independent of the other answers.
The success of each trial is defined as a correct answer with equal probability of success for each trial, i.e. 0.50.
The random variable <em>X</em> follows a Binomial distribution with parameter <em>n</em> = 9 and <em>p </em>= 0.50.
The probability mass function of <em>X</em> is:
Compute the value of P (X = 4) as follows:
Thus, the probability that the number of correct answers is 4 is 0.2461.
Answer:
The answer is option B.
Step-by-step explanation:
The prime number is 2
Since 1 + 1 = 2
And 1 is an odd number

Answer:
Step-by-step explanation:
Diameter of cone=14 cm
so, Radius of cone= 7cm
Height of cone= 8cm
∴ Volume of cone= 1/3*pi*r^2*h
=1/3*pi*49*8 cm^3
In Sphere, External Radius R=5cm
Let, Internal Radius = r
Volume of Sphere = External Volume- Internal Volume
= 4/3*pi*R^3-4/3*pi*r^3
=4/3*pi[R^3-r^3]
=4/3*pi[5^3-r^3]
But During Conversion Volume Remains Same
So, Volume of Sphere=Volume of Cone
4/3*pi[125-r^3]= 1/3*pi*49*8
4[125-r^3]=49*8
[125-r^3]=49*2
r^3=125-98
r^3=27
so, r =3 cm
Internal Radius= 3cm
So, Internal Diameter=3*2= 6cm
