After each soccer practice Scott Runs 4 sprints of 10 yards each complete exclamation to find how many practices it will take fo
Tpy6a [65]

Answer:

Scott will have to do 44 practices

Step-by-step explanation:

Let X be the number of yards per practice.

Let P = number of practice Scott needs to do.

Multiply 20 yards by 4 sprints

X = 20yards × 4 sprints = 80 yards

Number of yards he had to sprint per practice will be:

1 mile = 1760 yards

Converting from miles to yards

X = 1760 × 2 miles = 3520 yards

Number of practice,P Scott need to do = (3520/80)yards

Number of Practice,P = 44

Suppose 49 percent of the customers at Pizza Palooza order a square pizza, 71 percent order a soft drink, and 38 percent order b
Dmitry [639]

Answer:

b. No

Step-by-step explanation:

Represent

  • Square Pizza with S
  • Soft Drink with D

Such that

P(S) = 49\%

P(D) = 71\%

P(S\ and\ D) = 38\%

Required

Determine if events S and D are independent

Two events S and D are independent if:

P(S\ and\ D) = P(S) * P(D)

Substitute values for P(S) and P(D)

P(S\ and\ D) = 49\% * 71\%

Convert to decimals

P(S\ and\ D) = 0.49 * 0.71

P(S\ and\ D) = 0.3479

Convert to percentage

P(S\ and\ D) = 0.3479 * 100\%

P(S\ and\ D) = 34.79\%

The calculated P(S and D) is not equal to 38%

Hence, the events are not independent.
