Answer:
0.1611
Step-by-step explanation:
Uaing the binomial probability relation :
p = 0.5 ; q = 1 - p = 0.5
n = 10
Using the relation :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 7) = 10C7 * 0.5^7 * 0.5^3
P(x = 7) = 0.1172
x = 8 ;
P(x = 8) = 10C7 * 0.5^7 * 0.5^3
P(x =8) = 0.0439
P(x = 7 or x = 8) = 0.1172 + 0.0439 = 0.1611
Answer:
46°
Step-by-step explanation:
tan Ф = 21/20

= 46°
Answer:
Distributive property
Step-by-step explanation:
Here, we want to evaluate the property illustrated
From what we can see, we have that each of the inner values are multiplied by the outside value
This is simply a display of distributivity
We can conclude that we have a right distributive property in place here
<span>Prime is the best option describes the number 5.The number 5 is a prime because prime can be divided evenly by 1, or itself. And it must be a whole number greater than 1.But 6 can be divided evenly by 1, 2, 3 and 6 so it is NOT a prime number (it is a composite number).</span>
Answer:
1) The car can travel 623.3 km with 85 liters of petrol.
2) The car owner has to pay $303.8.
Step-by-step explanation:
1) The distance traveled with 85 L of petrol can be found as follows:
Hence, the car can travel around 623 km with 85 liters of petrol.
2) If the liter of petrol costs $2.25, then the amount of petrol that the car owner has to pay to travel a distance of 990 km is:
Therefore, the car owner has to pay $303.8.
I hope it helps you!
