What is the approximate distance from one corner of the soccer field to the opposite corner?
mario62 [17]

Answer:

117 yards

Step-by-step explanation:

From the diagram here, we can see that we are to calculate the diagonal of the rectangular football field

we can calculate this by the use of Pythagoras’ theorem which posits that the square of the hypotenuse = the sum of the squares of the two other sides

From the diagram, the diagonal is the hypotenuse while the other two sides complete the right triangle

let’s say the diagonal is length d

Mathematically;

d^2 = 100^2 + 60^2

d^2 = 10,000 + 3,600

d^2 = 13,600

d = √13,600

d = 116.62 yards which is approximately 117 yards

A marketing firm claims that its ad campaign will increase sales for a fast-food chain by 15%. In a random sample of 49 stores,
enyata [817]

Answer:

4.20

Step-by-step explanation:

Given data:

the average increase in sales 'x' = 18

ad campaign will increase sales for a fast-food chain 'μ'= 15

standard deviation 'σ'= 5

random sample of stores 'n'=49

In order to determine z-value, we use the formula i.e

z=( x-μ ) / (σ/\sqrt{n} )

z=( 18-15) / (5/\sqrt{49 )

z= 3/ 0.714

z= 4.20
