Answer:

AD = 48

Step-by-step explanation:

C is the midpoint of AD. B is the midpoint of AC. BC = 12.

Let's draw the line segment using the given information.

BC = 12

C is the midpoint AD so C divides the line segment AD into two halves.

B is the midpoint of AC so B divided the line segment AC into two halves.

So, AB = BC

AB = 12

Now let's find AC.

AC = AB + BC

AC = 12 + 12

AC = 24

AD = AC + CD

C divides AD into two halves. So AC = CD = 24

Therefore, AD = AC + CD

AD = 24 + 24

AD = 48

If US$1.00 is equivalent JA $75.00, What amount, in US dollars is equivalent JA $3300.00

Answer:

It is US $44.00 Equivalent

Step-by-step explanation:

Using ratios (essentially fractions):

1 US : 75 JA

1 US = 75 JA

Dividing both sides by 75 gives us:

$\frac{1}{75}$ US = 1 JA

So if we have 3300 JA we can multiply both sides to get:

44 US = 3300 JA

Duck #1 lays eggs whose weights are normally distributed with a mean of 70gramsand a standard deviation of 6 grams.Duck #2 lays

Genrish500 [490]

Answer:

26.11% probability that Duck #2’s egg weighs more than Duck #1’s egg

Step-by-step explanation:

When the distribution is normal, we use 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.

If an egg is randomly chosen from each duck, what is the probability that Duck #2’s egg weighs more than Duck #1’s egg?

Duck #2 egg will weigh more if the subtraction of duck's 2 egg by duck's 1 egg is larger than 0.

When we subtract normal distributions, the mean is the subtraction of the means. So

$\mu = 65 - 70 = -5$
