69 people got the free admission and that after that 154 more people came, so 20 people more and after than someone goes in for free!
Answer: <em>$3.83 per package</em>
Step-by-step explanation:
<em>Simply you need to use division</em>
<em>Divide 11.49 by 3</em>
<em>11.49/3</em>
<em>To which you will get</em>
<em>$3.83</em>
Step-by-step explanation:
<u>Y2 - Y1</u>
X2 - X1
<u>3 - 1</u>
2 - 1
= 2
y - Y1 = m (x - X1)
y - 1 = 2(x - 1) --- IN POINT SLOPE FORM
y - 1 = 2x - 2
+ 1 + 1
y = 2x - 1 --- IN SLOPE INTERCEPT FORM
QUESTION 12:
Slope intercept form -
- y = mx + b
- m represents the slope
- b represents the y - intercept AKA the starting point
- When the slope is negative, you go down
- When the slope is positive, you go up
ABOUT PROBLEM:
- Since the slope is negative, you go down 4, right 3, but start from the 2 then start doing the slope
- You have to put 2 on the y - line because it's the y - intercept AKA starting point
y = -4/3x + 2
Answer:
C
−3.5×10×(−7)×(−18.5)
Step-by-step explanation:
There are three negative signs in this expression. An odd number of negative signs will result in a Negative product.
Remember: "a negative times a negative is a positive!"
This is true whenever there is an EVEN number of negative signs.
The height of the softball when it travels 12 feet using the quadratic regression model is 5.53 foot.
<h3>What is the correlation coefficient?</h3>
Correlation coefficient is used to calculate how strong the relationship is between the two variables.
When there is a statistical relationship between two or more variables, then they are said to be in correlation.
The table represents the distance and height for softball travels after being hit by the batter.
- Distance x (ft) Height y (ft)
- 0 5
- 2 25
- 4 37
- 6 42
- 8 34
- 10 26
- Mean 5 28.167
The mean of the data of distance is 5 and the mean of the data of height is 28.167. The correlation coefficient is 0.9938.
The quadratic regression model for this model is given as,
At the 12 feet, the value of height y is,
Hence, the height of the softball when it travels 12 feet using the quadratic regression model is 5.53 foot.
