Answer:
Average cost per ball: $22.2
Step-by-step explanation:
Cost per ball: $22
Cost of 300 balls: 300 × 22 = $6600
Total No. of Orders: 3
Delivery fee per order: $20
Total Delievery fee: 20 × 3 =$60
Total cost including delivery cost: $6600 + $60 = $6660
census
random selection
voluntary response
Answer: random selection
Step-by-step explanation:
Given: 74 students were chosen from a local university to participate in a study. Every student attending the university had an equal possibility of being chosen.
Since we know that only in random selection the participants have the equal probability to get selected.
Hence, the sampling method used her is random sampling.
Answer:
there is a 0.8 percent of it landing on yellow
Step-by-step explanation:
The required simplified value of the square of binomial is 25d² - 70d³t + 49t²d^4 .
Given that,
To solve this square of binomial (5d - 7d²t)².
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Using (a - b)² = a² - 2ab + b²
(5d - 7d²t)² = (5d)² - 2 * 5d * 7d²t + (7d²t)²
(5d - 7d²t)² = 25d² - 70d³t + 49t²d^4
Thus, the required simplified value of the square of binomial is 25d² - 70d³t + 49t²d^4 .

The y-intercept is 50 ft. The balloon falls at a rate of 50 ft per minute.
The y-intercept is 1000 ft. The balloon begins to from an initial height of 1000 ft.
The slope is -50 ft per minute. The balloon is falling at 50 ft per minute.
It will take the balloon 20 minutes to reach the ground.
Answer:
The correct options are 3, 4 and 5.
Step-by-step explanation:
It is given that an air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute.
It means the initial height of air balloon is 1000. So, the y-intercept is (0,1000).
The ball falls at a rate of 50 ft per minute. So, the rate of change is
The height of balloon is defined as
Where, x is time in minutes.
The balloon will reach the ground when h(x)=0
Therefore the options 3, 4 and 5 are correct.
