Answer:
0.205 ; 0.117 ; 0.999
Step-by-step explanation:
Using binomial probability distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability of success, p = 0.5
P(x = 4) = 10C4 * 0.5^4 * 0.5^6
P(X = 4) = 0.205078125
B.) 3 heads and 7 tails
P(X = 7) = 10C7 * 0.5^7 * 0.5^3
P(X = 7) = 120 * 0.0009765625
P(X = 7) = 0.117
P(atleast one head)
P(x greater than equal to 1) = p(x =1) +... P(x = 10)
Using a binomial probability calculator :
P(x greater than equal to 1) = 0.999
Answer:
3x + 7
Step-by-step explanation:
<u>Step 1: Distribute the plus</u>
(x + 4) + (2x + 3)
x + 4 + 2x + 3
<u>Step 2: Combine like terms</u>
x <u>+ 4</u> + 2x <u>+ 3</u>
<em>3x + 7</em>
<em />
Answer: 3x + 7
<u>If needed solve</u>
3x + 7 - 7 = 0 - 7
3x / 3 = -7 / 3
<em>x = -7/3</em>
Answer:
17........ hope its helpful
Step-by-step explanation:
⇒2x+2y=14⇒2x+2y=14 or x+y=17x+y=17
It is understood that 5.4^0 is the number 5.4 raised to the power zero.
There is a rule for this: any number raised to the power zero is 1.
So, 5.4 ^ 0 = 1.
You can show that any number raised to the power of zero is 1 using this:
A^0 = (A)^(m - m) = [A^m] / [A^m]
Given that the numerator and the numerator of that fraction are equals the result is 1.
You multiply 11 and 10 which gives you 110%. So 10% of 110 gives you 11 .Hope i helped:)
