A because 7 an hour mean that your equation is 7x-6 instead of 6x-7 like the other ones.

Wangari plants trees at a constant rate of 1212 trees every 33 hours. Write an equation that relates pp, the number of trees Wan

igor_vitrenko [27]

Answer:

$p=4h$

Step-by-step explanation:

Let p be the number of trees Wangari plants, and h be the time she spends planting them in hours.

We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.

Let us find number of trees planted in 1 hour by dividing 12 by 3.

$\text{Number of trees planted in 1 hour}=\frac{12\text{ plants}}{3\text{ hour}}$

$\text{Number of trees planted in 1 hour}=4\frac{\text{ plants}}{\text{ hour}}$

We can represent this information as: $p=4h$

Therefore, the equation $p=4h$ relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.

Due to manufacturing error, three cans of regular soda were accidentally filled with diet soda and placed in a 12-pack. Suppose

zzz [600]

Answer:

a) 2/44 = 0.045

b) 9/22 = 0.409

Step-by-step explanation:

a) The probability the first can is diet soda is 3/12.

The probability the second can is diet soda is 2/11.

The probability of both is (3/12) (2/11) = 2/44 ≈ 0.045.

Alternatively, you can use combinations:

₃C₂ × ₉C₀ / (₁₂C₂) = 2/44

b) If the first can is diet soda, and the second can isn't, the probability is (3/12) (9/11) = 9/44.

If the first can isn't diet soda, and the second can is, the probability is (9/12) (3/11) = 9/44.

The total probability is 9/44 + 9/44 = 9/22 ≈ 0.409.

Alternatively, using combinations:

₃C₁ × ₉C₁ / (₁₂C₂) = 9/22

The answer to your question is See the picture below

Step-by-step explanation:

Analysis of the graphs

a) In the first graph, we observe that Natasha is running after 1 h and 1/4, the comeback for to her origin, finally she continues running forward. This option is incorrect.

b) In the second graph, Natasha runs for 1 1/4 hours, after this time, she comes back to her origin, takes a rest and continues running forward. This answer is incorrect.

c) In the third graph, Natasha runs for 1 1/4 hour, takes a rest and comes back to the origin. This option is incorrect.

d) In the forth graph, Natasha runs for 1 1/4 hour, takes a rest and continues running upwards. This is the right option.
