Assume that the readings at freezing on a batch of thermometers are Normally distributed with mean 0°C and standard deviation 1.

Answer:

$P_{60} = 0.254$

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 0

Standard Deviation, σ = 1.00

We are given that the distribution of readings at freezing on a batch of thermometers is a bell shaped distribution that is a normal distribution.

Formula:

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

We have to find $P_{60}$

P(X<x) = 0.0600

We have to find the value of x such that the probability is 0.600

P(X < x)

$P( X < x) = P( z < \displaystyle\frac{x - 0}{1})=0.600$

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

$\displaystyle\frac{x - 0}{1} = 0.254\\x = 0.254$

$\bold{P_{60} = 0.254}$

Please answer my question

Ghella [55]

Interval notation uses parenthesis and brackets, while inequality notation uses inequality symbols.

Interval notation: [-4, 8)

Inequality notation: $-4\leq x$

x >= -4, x < 8

---For inequality notation, it can also be written as two separate inequalities. I am not sure what your teacher is looking for, so I will provide both the compound and separate formats.

Interval notation: (-infinity, 7)

Inequality notation: x < 7

Interval notation: (-infinity, -6) U (0, infinity)

Inequality notation: $-6> x \geq 0$

x < -6, x >= 0

Hope this helps!

A function assigns the values. The function for this model can be written as y=-4x+50.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

As it can be seen from the graph that the function is linear, therefore, we can write,

y = mx + c

Given two points of the graph, therefore, we can write for the first point,

30 = m(5) + c

30 = 5m + c

c = 30 - 5m

Also, for the second point,

y = mx + c

26 = 6m + c

Substitute the value of c,

26 - 6m = 30 - 5m

-6m + 5m = 30 - 26

-m = 4

m = -4

Now, substitute the value of m in any one of the equation formed above,

c = 30 - 5m

c = 30 - 5(-4)

c = 50

Hence, the function for this model can be written as y=-4x+50.
