Answer:

The two numbers are 36 and 9

Step-by-step explanation:

Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48

We know that: n <44, 48

Let's try some values:

45 - 40 = 4

45- 36 = 9

45- 28 = 17

45- 24 = 21

Pattern: The lesser a natural numer's absolute value, the greater [larger number] it produces. (Bold = "larger numbers")

We recognize something: 36 + 9 = 45 and 36 is exactly 4 times greater than 9.

The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of at the freezing poin

tatyana61 [14]

Answer:

The $96^{th}$ percentile is 1.751

Step-by-step explanation:

The following information is missing in the question:

Mean,

$\mu = 0^\circ C$

Standard Deviation,

$\sigma = 1^\circ C$

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

Formula:

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

We have to find the value of x such that the probability is 0.96

$P( X < x) = P( z < \displaystyle\frac{x - 0}{1})=0.96$

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

$\displaystyle\frac{x}{1} = 1.751\\\\x = 1.751$

$P_{96} = 1.751$

1.751 degree Celsius is the thermometer reading corresponding to $96^{th}$ percentile.
