Answer:
The total number of samples that contain at least 3 red balls is 115.
Step-by-step explanation:
Total number of balls = 11
Total number of red balls = 6
Total number of white balls = 5
A sample of 4 balls is to be selected that contain at least 3 red. It means either 3 out of 4 balls are red or 4 out of 4 ball are red.
Combination formula:
Using this formula we get
Therefore the total number of samples that contain at least 3 red balls is 115.
Answer:
-19
Step-by-step explanation:
Rewrite the equation from highest exponent to lowest:
-19x^7-18x^6+15x^4-26x^3
Coefficients are the numbers in front of the exponent, so the leading coefficient is what is attached to the highest exponent value.
-19x^7 is the highest exponent, so -19 is the highest coefficient.
Answer:
about 7.14 feet
Step-by-step explanation:
a^2+b^2=c^2
100=7^2+a^2
100=49+a^2
51=a^2
7.14=a

Answer:
440 I believe is the answer
Step-by-step explanation:
307.8 divided by( 7/10), which gets you 439.714285714. But you round up because if you round down, it would not be enough steps :)
First, we find 3% of $10.51.
Then, we add this increase to $10.51.
<h2>Hence, the new wage per hour is $10.83.</h2>
