Answer:

a. 90/ 4.5 = 20 flags per yard

b. 4.5/ 90 = 0.05 = 5 hundredths of a yard

c. 0.75 x 3 colours = 2.25 yards

4.5 = 90 flags so 4.5/2 = 2.25 = 45 flags

Justifies she is correct when saying 45 flags can be made with 3 x 0.75 material as this is equal to 2.25 yards which is half of 4.5 yards equal to 90 flags.

To find 4.5 we have 3 pieces of material to begin with for part a and part b

This shows 1.5 x 3 = 4.5 yards

To find 2.25 we have 3 pieces of material in part c.

This shows 0.75 x 3 = 2.25 yards

Answer:

The first two is x=60

Step-by-step explanation:

1.5/90 = 1/x

1.5x = 90 x 1

1.5x/1.5 = 90/1.5

x = 60

Janine inflated a ball to a radius of 18 cm and another ball to a radius of 12 cm.

Sladkaya [172]

Volume of a ball = (4/3)πr³

When r = 18cm, V = (4/3)×3.14×18³ =24416.64 cm³
When r = 12cm, V = (4/3)×3.14×12³ =7234.56 cm³
Difference = 24416.64 - 7234.56 = 17182.08 cm³

the volume of air in the larger ball is <span>17182.08 cm³ greater than smaller ball </span>

Occasionally an airline will lose a bag. Suppose a small airline has found it can reasonably model the number of bags lost each

julia-pushkina [17]

Answer:

a) The probability that the airline will lose no bags next monday is 0.1108

b) The probability that the airline will lose 0,1, or 2 bags next Monday is 0.6227

c) I would recommend taking a Poisson model with mean 4.4 instead of a Poisson model with mean 2.2

Step-by-step explanation:

The probability mass function of X, for which we denote the amount of bags lost next monday is given by this formula

$P(X=k) = \frac{e^{-2.2} * {2.2}^k }{k!}$

$P(X=0) = \frac{e^{-2.2} * {2.2}^0 }{0!} = 0.1108$

The probability that the airline will lose no bags next monday is 0.1108.

b) Note that $P(X \in \{0,1,2\} = P(X=0) + P(X=1) + P(X=2)$ . And

$P(X=0)+P(X=1)+P(X=2) = e^{-2.2} * (1 + 2.2 + 2.2^2/2) = 0.6227$

Therefore, the probability that the airline will lose 0,1, or 2 bags next Monday is 0.6227.

c) If the double of flights are taken, then you at least should expect to loose a similar proportion in bags, because you will have more chances for a bag to be lost. WIth this in mind, we can correctly think that the average amount of bags that will be lost each day will double. Thus, i would double the mean of the Poisson model, in other words, i would take a Poisson model with mean 4.4, instead of 2.2.

Find the volume of the cylinder.

Aneli [31]

Answer:

144π or 452.16 units³

Step-by-step explanation:

The formula for volume of a cylinder is $\pi r^2 h$ . We can use the given values for radius and height to find the volume of the cylinder.

<h3>Finding the Volume</h3>

$V=\pi r^2 h\\V=\pi6^2(4)\\V=\pi36(4)\\V=144\pi \ OR\ 452.16$

The volume of the cylinder is 144π or 452.16 units³.
