Answer:
The number of test required is: 55
Explanation:
Using combination formula:
n!/x!(n-x)!
= 11!/2!(9)!
= 55
Answer:
y = -4x + 10
Step-by-step explanation:
I am going to assume you are trying to write the equation of a line.
4x + y = 10
4x - 4x + y = 10 - 4x
y = -4x + 10
As they are both on the same y axis, (-2), that means you just need to find the difference between 5 and - 6 which is 11. Therefore the answer is 11 units. Hope this helps! :)
Answer:
20
Step-by-step explanation:
To find the mean, add up all the numbers in the data set, and then divide by the number of terms in the data set
<em>Add </em>
Add up the numbers in the data set
17+24+26+13
80
<em>Divide </em>
Divide by the number of terms in the data set
In this case, there are 4 terms (17, 24, 26, 13)
80/4=20
The mean of the data set is 20
Answer:
p = 11.2
Step-by-step explanation:
The computation is shown below:
Data provided in the question
2.6(5.5p – 12.4) = 127.92
Now
Distributive Propertyis
14.3p - 32.24 = 127.92
Addition Property is
14.3p = 127.92 + 32.24
Division Property is
14.3p ÷ 14.3 = 160.16 ÷ 14.3
p = 11.2
We simply find the value of p by applying the distributive property, addition property, and the division property and the same is to be considered
