Answer: 5/7
Step-by-step explanation: 27 and 9 are both irrelevant numbers.
If we see here, it is given that they have a cat. 7 people have a cat! And because those 5 students who have both are listed under both categories, there are 5 students in the 7! Therefore, 5/7 is the desired probability...
Answer:
The factors of given expression are 10+10√2 and 10-10√2.
Step-by-step explanation:
We have given a quadratic expression.
s²-20s-100
We have to find factors of given expression.
We use quadratic formula to find factors.
x = (-b±√b²-4ac) / 2a
From given expression, a = 1 , b = -20 and c = -100
Putting values in above formula, we have
x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)
x = (20±√400+400 ) / 2
x = (20±√800) / 2
x = (20± √400×2) / 2
x = (20±20√2) / 2
x = 10±10√2
Hence, the factors of given expression are 10+10√2 and 10-10√2.
A normal density curve is symmetrical
The correct to the question above would be high. If Sue and Kiana are counting the number of computers that they had repaired every day for 2 weeks and if their manager also made a line plot from these data, it would be a high degree of over of the two data sets' distributions.
Answer:
32.6 - y= 10.2
Step-by-step explanation:
The equation to solve this problem can be written as
32.6 - y= 10.2
Where y is the number that was substracted from 32.6.
If we make y subject of formula we have
y= (32.6-10.2)
y=22.4
Which means the number that was substracted from 32.6 is 22.4 and there difference is 10.2
