Answer:
5
Step-by-step explanation:
The 32 that have blue and green ribbons include the 16 that have all three, so there are only 32 -16 = 16 that have only blue and green ribbons.
The 31 that have green and white ribbons likewise include the 16 with all three, so there are only 31 -16 = 15 that have only green and white ribbons.
The 38 that have blue and white ribbons include the 16 with all three, so there are only 38 -16 = 22 that have only green and white ribbons.
__
If we add the numbers of blue, green, and white ribbons, we are counting twice the numbers that have 2 ribbons, and 3 times the numbers that have 3 ribbons. We want to count each kind of ribbon-holder only once. Hence the number of individual dogs with any number of ribbons is only ...
62 +55 +63 -(16 +15 +22) -2(16) = 95
Of the 100 dogs, 95 have ribbons, so 5 dogs have not learned any tricks.
- It is linear as the equation performs ax+by +c
- y = 90.2x - 177670
- number of student to enroll 2011 is 3722
Step-by-step explanation:
- Linear is a straight line.
- Quadratic is a square which generates parabola.
- Quadratic formula is (ax)^2 + bx + c = 0.
- Linear formula is ax+bx + c = 0
- To forecast time series data modelling can be used.
- To form a linear equation y = mx + c.
- After finding x is the required value , m is the intercept and C constant.
- X axis have years and Y axis has the value.
- to find number of students x is 90.2 * 2011 - 177670.
- The result comes to 3722.
- In Data analysis predictive modeling is the second phase.
- It is important because it helps in associating to variables.
Answer:
If 550 toys are made in a day, and 6% of them are defective, about 33 of them will be defective.
Step-by-step explanation:
To calculate the number of toys that will be defective, move the decimal of the percentage 2 place to the left. So the 6% will turn into 0.06, then you would multiply 550 by 0.06. Resulting in about 33 toys being defective.
6% = 0.06
-
550 x 0.06 = 33
Answer:
B. equivalent
Step-by-step explanation:
Our two equations are:
Let's use substitution and plug in the expression 
for y in the second equation. That way, we're getting rid of a variable so we can solve for the other:
This means that there are an infinite number of solutions possible for this system - any x value will work. So, the answer is equivalent, because these two equations are essentially the same.
