Airida [17]

If Jeanette take its 40 times in one month she would be on time 39 (39.2) times.

NO, the light-rails claim is not accurate if she is late 6 times.

The light rails claim would be accurate if it stated the service is on time 85% of the time.

Given: line a is parallel to line b.

mina [271]

Answer:

Step-by-step explanation:

To solve this, we need to use the corresponding angles theorem. It states that when a transversal line cuts across 2 parallel lines, then the corresponding angles there-in are congruent or equal.

Now the pair of corresponding angles we have in this question are as follows;

1 and 5

3 and 7

2 and 6

4 and 8

All these pairs are congruent corresponding angles.

Looking at the options, option D is correct

Zarrin [17]

Answer:

x = 16/5

Step-by-step explanation:

2x + 14 -34 = 4x - 11x + 4x - 4

2x - 20 = -3x - 4

The distribution of head circumference for full term newborn female infants is approximately normal with a mean of 33.8 cm and a

enyata [817]

Using the normal distribution, it is found that 95.65% of full term newborn female infants with a head circumference between 31 cm and 36 cm.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

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

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

$\mu = 33.8, \sigma = 1.2$

The proportion of full term newborn female infants with a head circumference between 31 cm and 36 cm is the <u>p-value of Z when X = 36 subtracted by the p-value of Z when X = 31</u>, hence:

X = 36:

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

$Z = \frac{36 - 33.8}{1.2}$

Z = 1.83

Z = 1.83 has a p-value of 0.9664.

X = 31:

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

$Z = \frac{31 - 33.8}{1.2}$

Z = -2.33

Z = -2.33 has a p-value of 0.0099.

0.9664 - 0.0099 = 0.9565.

0.9565 = 95.65% of full term newborn female infants with a head circumference between 31 cm and 36 cm.
