Answer:
The chance that there will be exactly 2 heads among the first five tosses and exactly 4 heads among the last 5 tosses is P=0.0488.
Step-by-step explanation:
To solve this problem we divide the tossing in two: the first 5 tosses and the last 5 tosses.
Both heads and tails have an individual probability p=0.5.
Then, both group of five tosses have the same binomial distribution: n=5, p=0.5.
The probability that k heads are in the sample is:

Then, the probability that exactly 2 heads are among the first five tosses can be calculated as:

For the last five tosses, the probability that are exactly 4 heads is:

Then, the probability that there will be exactly 2 heads among the first five tosses and exactly 4 heads among the last 5 tosses can be calculated multypling the probabilities of these two independent events:

I assume that if we write the equation in its mathematical form it will appear like this:
T = 50 + (N - 40)/4
Substituting the value of T given,
58 = 50 + (N-40)/4
The value of N from the generated equation above is equal to 72. Therefore, the Snowy Tree Crickets chirp 72 times per minute at a temperature of 58°F.

Answer:
B: 54 square feet
Step-by-step explanation:
There are 3 feet in 1 yard. The scale model is 6 square yards.
Multiply 6 by 3 to get the amount of square yards.
There are 18 square yards in the actual playground.
Since there are 3 feet in a yard, multiply 18 by 3.
This gives you your answer:
54 square feet
