Terrence is folding paper cranes at a constant rate. Write an equation to describe the relationship between c, the number of cra
Vanyuwa [196]

Answer:

It is c = kt.

Step-by-step explanation:

This is direct variation . As the time increases the number of cranes increases.

The equation is c = kt  where k is the constant  of variation.  In this case it will be a positive value because c is increasing with time.

If they make 20 cranes in 10 minutes then we can find the value of k by plugging in these values;

20 = k * 10

g = 20/10

k = 2.

So they make 2 cranes per minute.

If the pointer in the figure is spun twice, find the probability that the pointer lands on red (R) both spins.
r-ruslan [8.4K]

The probability of the pointer lands on red(R) both spin = \frac{1}{36}

Step-by-step explanation:

Given,

The number of parts = 6

The pointer is spun twice.

To find the probability of the pointer lands on red(R) both spin.

Formula

Probability of an event = number of required outcomes ÷ the total number of outcomes.

P(A and B) = P(A)×P(B)

Now,

For one spin,

A = RED comes.

For second spin,

B = RED comes

So,

P(A) = \frac{1}{6} and P(B) =  \frac{1}{6}

Then,

P(A and B) =  \frac{1}{6} × \frac{1}{6}  = \frac{1}{36}

Hence, the probability of the pointer lands on red(R) both spin = \frac{1}{36}

Paladinen [302]

Each star has a 20% difference.

A four star rating would be above the bottom 60% ( 1, 2 and 3 stars) but be below the top 20%. (5 stars).
