Use the unit fractions 36in./1yd and 2.54 cm/1in. Convert 11 yd to cm.
madam [21]

Answer:

1,005.84 cm

Step-by-step explanation:

Given the unit fractions, 36 in/1 yd (i.e. 36 inches = 1 yard), and 2.54 cm/1 in (i.e. 2.54 cm = 1 inches), to convert 11 yd to cm, first convert to inches, then convert what you have in inches to cm.

Thus:

Converting 11 yd to inches:

36 in = 1 yd

11 yd = 36*11 = 396 in

Converting 396 in to cm:

2.54 cm = 1 in

396 in = 2.54*396 = 1,005.84 cm

The scores on a standardized exam are normally distributed with a mean of 400 and a standard deviation of 50.
S_A_V [24]

Using the normal distribution, it is found that approximately 40% of the scores are greater than 413.

<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.

In this problem, we have that the mean and the standard deviation of the scores are given by:

\mu = 400, \sigma = 50

Approximately 40% of the scores are greater than the 60th percentile, which is <u>X when Z = 0.253</u>.

Then:

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

0.253 = \frac{X - 400}{50}

X - 400 = 50(0.253)

X = 412.65.

Rounding up, approximately 40% of the scores are greater than 413.

We can find a system of congruences where x≡a (mod 4) x≡b (mod 5) where the solution is x≡7 (mod 20).
Nonamiya [84]

If x ≡ 7 (mod 20), then

x ≡ 7 ≡ 27 ≡ 47 ≡ 67 ≡ 87 ≡ … (mod 20)

or equivalently, x = 7 + 20k for some integer k.

Taken mod 4, we have

x ≡ 7 + 20k ≡ 3 (mod 4)

and mod 5,

x ≡ 7 + 20k ≡ 2 (mod 5)

so that a = 3 and b = 2.
