Based on the data in this two-way table, which statement is true? Type of Flower/Color Red Pink Yellow Total Rose 40 20 45 105 H
2 answers:
Answer:
A. a flower being pink and a flower being a rose are independent of each other.
Step-by-step explanation:
Type of Flower/Color Red Pink Yellow Total
Rose 40 20 45 105
Hibiscus 80 40 90 210
Total 120 60 135 315
Now the probability, if the flower is pink =
The probability that the flower is rose =
Te probability that flower is pink and rose = =
Also we can see,
Therefore, we can state that events are independent.
Hence, option A is correct.

Step-by-step explanation:
<h3> The missing question is: "What is the Functions formula A(t)=?"</h3><h2 />The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
According to the data given in the exercise, you know that:
- represents the area to paint the Hiros' romm as a function of time.
- The rate he painted the room was 8 square meters per hour.
- The area left to paint after 3 hours was 28 m².
Therefore, based on this, you can idenfity that:
1. The slope of the line is:
2. One of the point on the line is:
So you must substitute the slope and the coordinates of that point into and then solve for "b" in order to find its value:
Therefore, you can determine that the function is:
Answer:
Step-by-step explanation:
The slope of the line is
Using the point (-2, 0) to substitute into point-slope form, we get the equation to be
