For this problem, we use the repeated trials equation:
P = n!/r!(n-r)!*p^(n-r)*q^r
where
P is the total probability of having r successful trials out of the total n trials. p is equal to 13/58, while q is equal to 1 - 13/58.
P = 4!/4!(4-4)!*(13/58)^(4-4)*(1 - 13/58)^4
P = 0.362 or 36.2%
These two angles are supplementary, meaning that there sum is 180 degrees. To solve this make a formula:
97 + x = 180
Subtract 97 to both sides to isolate x
97 - 97 + x = 180 - 97
x = 83

Answer:
3K+1
Step-by-step explanation:
If this is a Khan academy question for the question 5k+(-2k)-(-1) the correct answer is 3K+1
The answer is 9 you have to multiply 1/4 three times which gives you 1/64 then you take 576 and multiply it by 1/64 which gives you 9. Hope this helps.
Answer:
x = + 14.88 km
Step-by-step explanation:
Let's solve for x using the Pythagorean Theorem.
The length of the hypotenuse is 15.8 km; that of the shorter leg is 5.3 km.
Since a² + b² = c², we get:
(5.3 km)² + x² = (15.8 km)²
Solving for x², we obtain (15.8 km)² - (5.3 km)² = 249.64 km² - 28.09 km²
The last expression returns the value 221.55 km² for x²
Taking the square root of both sides, we get x = + 14.88 km
