Answer: A line is the undefined term which best defines the arrow pictured

Step-by-step explanation:

There are three undefined terms in geometry are as follows

1) point → has no dimensions

2) line → has one dimension

3) plane. → has two dimensions

In the given picture, a line is the only undefined term which best fits to define the arrow pictured since arrow has only length, thus it has one dimension as a line.

The answer is B. A point is a location, and a plane is represented by a rectangle or a parallelogram.

The weight for crates of eggs is normally distributed with a mean weight of 34.6 pounds and a standard deviation of 2.8 pounds.

Bingel [31]

Answer:

0.5532

Step-by-step explanation:

P( 31<X<35.7)

P(X>31)= P(Z>(31-μ)/σ)

= P(Z>(31-34.6)/2.8)

= P(Z> -1.2857)

P(X<35.7)= P(Z<(35.7-μ)/σ)

= P(Z<(35.7-34.6)/2.8)

=P(Z< 0.392857)

From z-distribution table

P(Z< -1.29)= 0.09853

p(Z< 0.39) = 0.65173

P( 31<X<35.7)= P(Z<0.39)- P(Z<-1.29)

= 0.65173- 0.09853

=0.5532

The pregnancy length in days for a population of new mothers can be approximated by a normal distribution with a mean of 270 day

dusya [7]

Answer:

a) 281 days.

b) 255 days

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 270, \sigma = 8$
