Answer:
Team B scored 17 points and team A scored 30 points.
Step-by-step explanation:
17 + 13 = 30
30 + 17 = 47
47 total points
Answer:
The difference quotient is 4.
Step-by-step explanation:
Given that:

To find:
Difference quotient = ?
where 
Solution:
Formula for Difference quotient is given as:

First of all, let us find out 
Replacing
with 

Now,

Putting the above value in:

We are given that, 

So, the difference quotient is 4.
Deacon Middle School
5x = number of boys
4x = number of girls
where x is some unknown number for now
(number of boys)+(number of girls) = 270 students total
5x+4x = 270
9x = 270
x = 270/9
x = 30
Since x = 30, this means
number of girls = 4x
number of girls = 4*30
number of girls = 120
There are 120 girls at Deacon Middle School
-----------------------------------------
Similarly, for Meadow Middle school
number of boys = 4y
number of girls = 5y
for some number y
(number of boys) + (number of girls) = 180 students total
4y+5y = 180
9y = 180
y = 180/9
y = 20
making,
number of girls = 5*y
number of girls = 5*20
number of girls = 100
so there are 100 girls at Meadow Middle School
-----------------------------------------
In summary so far, there are...
120 girls at Deacon Middle School
100 girls at Meadow Middle School
In total 120+100 = 220 girls from both schools
This is out of 270+180 = 450 students total
Divide the two values (220 and 450) to get
220/450 = 22/45
The final answer is 22/45
It cannot be reduced further as there are no common factors (other than 1) between 22 and 45
Answer:linear
Step-by-step explanation:
Answer: Our required probability is 0.304.
Step-by-step explanation:
Since we have given that
N = 21
Number of improperly drilled holes k = 4
Number of properly drilled holes = N-k= 21-4=17
Let X be the number of improperly drilled holes in a sample of 5.
We will use "Binomial distribution":

So, our required probability is 0.304.
