HELP ASAP A drawing class was assigned a final project where students had to choose one art
medium and one subject. The teacher kept track of the types of projects submitted.
The probability that a student used chalk is 0.3, the probability that a student chose to
draw a plant is 0.6, and the probability that a student used chalk and chose to draw a
plant is 0.2.
What is the probability that a randomly chosen student used chalk or chose to draw
a plant?

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
