The probability that fewer than 4 of them are successful are 0.9527
<u>Explanation:</u>
Given:
number of trials, n = 6
p(successful) = 0.85
P(x >= 4) = ?
The problem can be solved using binomial probability formula.
P(x >= 4) = 1 - binomcdf(6,0.85,4) = 1 - 0.0473
= 0.9527
Therefore, the probability that fewer than 4 of them are successful are 0.9527
Answer:
500
Step-by-step explanation:
A = the unknown number that we need to find
A x 13/100 = 65
=> A x 13 = 6500
=> A = 6500 / 13
=> A = 500
13% of 500 is 65.
Let's check whether the answer is correct or not.
=> 500 x 13/100
=> 5 x 13
=> 65.
So, the number whose 13% is 65 is 500
Answer:
In addition, from the response shown, using a graphical calculator brings the following benefits:
1) You can write the system of linear equations as big as you want. This is: systems 3 * 3, 4 * 4, 5 * 5.
2) The response to systems of equations greater than 2 * 2 can be complicated when you graph the solution, therefore, the graphing calculator can be much more efficient in these cases.
3) You can write the linear equations in any way. Resolving by hand you should probably rewrite the system of equations to find the solution.

Answer:
The sale price will be 143.20
Step-by-step explanation:
20% of 179 is 35.80
179 - 35.80 = 143.20
Answer:

Step-by-step explanation:

Subtract 10 from both sides:

Divide both sides by

For example, if the total charge is $27.50 and the distance ridden is 250 mi, we can calculate the additional cost per mile, as such:
