point K is between points M and Q. If line segment MK = 7 inches and line segment MQ = 15 inches, whst is the measurement of KQ?

BigorU [14]

The total length of a line segment is the sum of the lengths of its parts.

MQ = MK + KQ . . . . . . express the relationship between the segments

15 in = 7 in + KQ . . . . . fill in the given information

(15 - 7) in = KQ . . . . . . .subtract 7 in

KQ = 8 in . . . . . . . . . . . simplify

The measurement of KQ is 8 inches.

How much difference do a couple of weeks make for birth weight? Late-preterm babies are born with 34 to 36 completed weeks of ge

stiks02 [169]

Answer:

a) 0.3277

b) 0.0128

Step-by-step explanation:

We are given the following information in the question:

N(2750, 560).

Mean, μ = 2750

Standard Deviation, σ = 560

We are given that the distribution of distribution of birth weights is a bell shaped distribution that is a normal distribution.

Formula:

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

a) P (less than 2500 grams)

P(x < 2500)

$P( x < 2500) = P( z < \displaystyle\frac{2500 - 2750}{560}) = P(z < -0.4464)$

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

$P(x < 2500) = P(z < -0.4464) = 0.3277 = 32.77\%$

b) P ((less than 1500 grams)

P(x < 1500)

$P( x < 1500) = P( z < \displaystyle\frac{1500 - 2750}{560}) = P(z < -2.2321)$

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

$P(x < 1500) = P(z < -2.2321) = 0.0128 = 1.28\%$

When calculating the circumference of a circle, sometimes the radius is given instead of the diameter. What is the relationship

marin [14]

Answer:

Option A ( radius is twice the daimeter )

Step-by-step explanation:

The relationship between radius and daimeter is given as

Radius² = Daimeter ⇒ r² = d

And cricumference can be calculated with radius

As circumference is 2πr
