Which equation represents a proportional relationship?

iren2701 [21]

The equation that represents a proportional relationship is:

y = 32x

Because:

y/x = 32

So that implies that y is directly proportional to x.

Note that other equations represent a proportional relationship in some form, only that the relationship y = 32x is the only direct proportional relationship.

The number of times per minute that a hummingbird's wings flap is normally distributed with a mean of 145 and a standard deviati

klemol [59]

Answer:

a) 0.0013

b) 0.9544

c) 84.13 percentile.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 145

Standard Deviation, σ = 2

We are given that the distribution of wings flap is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P( flaps its wings more than 151 times a minute)

$P( x > 151) = P( z > \displaystyle\frac{151 - 145}{2}) = P(z > 3)$

$= 1 - P(z \leq 3)$

Calculation the value from standard normal z table, we have,

$P(x > 151) = 1 - 0.9987 = 0.0013$

b) P( flap their wings between 141 and 149 times per minute)

$P(141 \leq x \leq 149)\\\\ = P(\displaystyle\frac{141 - 145}{2} \leq z \leq \displaystyle\frac{149-145}{2})\\\\ = P(-2 \leq z \leq 2)\\\\= P(z \leq 2) - P(z < -2)\\= 0.9772 - 0.0228 = 0.9544$

c) Percentile of hummingbird that flaps its wings 147 times a minute

$P( x < 147) = P( z < \displaystyle\frac{147 - 145}{2}) = P(z < 1)$

Calculation the value from standard normal z table, we have,

$P(x < 147) = 0.8413$

Thus, A hummingbird that flaps its wings 147 times a minute is in the 84.13 percentile.

A train travels with a constant speed of 88 km/h. How far can it travel in 3 hours??? PLEASE HELPP

blagie [28]

Since it is traveling at a constant rate of 88 km per hour, if we were to find out what it could travel in 3 hours we would multiply 88 by 3. If done correctly you should get 264. Hopefully this helps you!
