Answer:
Step-by-step explanation:
DE :
If y is a solution of given DE then it satisfied the DE.
Differentiate w.r.t t
Using the formula
LHS:
RHS
By using the formula
LHS=RHs
Hence, y is a solution of given DE
The manager at a golf course found that the population mean length of the holes at the golf courses is 415.9 yd. In this context, is the number 415.9 a parameter or a statistic?
Answer: The number 415.9 is a parameter because it represents the population characteristic.
<u>Explanation:</u>
Parameter: Parameters are numbers that summarize the entire population. For example the population mean summarizes the entire population, similarly population standard deviation describes the characteristic of entire population.
Statistic: Statistic are numbers that describes the sample. For example, the sample mean summarizes the sample which is drawn from the population, similarly the sample standard deviation describes the characteristic of sample.
Therefore, the population mean length of the holes at the golf courses (415.9 yd) is parameter.
She needs 8 more dollars.
if you multiply 3 times 5 equals 15
and 4 times 3 equals 12
then add that which is 27
35 minus 27 is 8.

Answer:
The area of the rectangular deck is 36 sq feet.
Step-by-step explanation:
Let the width of the deck = k ft
So, the length of the deck = (4k) ft
Now, perimeter = 30 ft
PERIMETER OF A RECTANGLE = 2(LENGTH + WIDTH)
⇒2( k + 4k) = 30
or, 2 x 5k = 30 ⇒ 10k = 30
⇒ k = 30/10 = 3
So, the width of the deck = k = 3 ft
Length of the deck = 4k = 3 x 4 = 12 ft
Now, AREA OF A RECTANGLE = LENGTH X WIDTH
So, the area of the rectangular deck = 3 ft x 12 ft
= 36 sq feet
Hence, the area of the rectangular deck is 36 sq feet.
