Answer:

Step-by-step explanation:

Proportionality concerns the ratio between two values, so C and D can be knocked off since they talk about difference. So that leaves us A and B. To find out if m and k are proportional, let's find the ratio between them (which means dividing them) for each set of speeds:

11.0/17.699 = 0.6215040398

26.0/41.834 = 0.6215040398

34.0/54.706 = 0.6215040398

We can see that all of the ratios return the same number, which means that the ratio of m to k is constant, so therefore the relationship is proportional, and the answer is A.

A rock is dropped off a 500-foot cliff. After 1 second the rock is traveling 32 feet per second then after 4 seconds the rock st

professor190 [17]

Answer:

Part A:

The equation describing the relationship between speed and time is:

s = 32t

Ordered pairs of the form (speed, time) are:

(32, 1)

(64, 2)

(96, 3)

(128, 4)

Part B:

s = 32t

s = 32 * 5 = 160 feet per second

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Height of the cliff = 500 feet

Speed after one second = 32 feet per second

Speed after four seconds = 128 feet per second

2. Assume the relationship between time, t, and speed, s, is linear and write an equation describing the relationship. Use ordered pairs of the form (speed, time)

The equation describing the relationship between speed and time is:

s = 32t

Ordered pairs of the form (speed, time) are:

(32, 1)

(64, 2)

(96, 3)

(128, 4)

3. Use the equation to determine the speed of the rock 5 seconds after is dropped.

s = 32t

s = 32 * 5 = 160 feet per second

mihalych1998 [28]

Answer:

Step-by-step explanation:

Given that a convenience store regularly buys mangoes from a wholesale dealer. For every shipment, the manager randomly inspects five mangoes from a box containing 20 mangoes for damages due to transportation. Suppose the chosen box contains exactly 2 damaged mangoes.

In the selected box 18 good mangoes and 2 damaged mangoes are there

a) Find the probability that the first mango is not damaged.

= prob of selecting 1 from any one of 18 good mangoes = $\frac{18}{20} =0.90$

b. Find the probability that neither of the mangoes is damaged. =

Prob of selecting 2 from 18 good mangoes

= $\frac{18C2}{20C2} =0.5276$

c. Find the probability that both mangoes are damaged.

= Prob of selecting 2 from 2 bad mangoes

= $\frac{2C2}{20C2} =0.005263$
