Every now and then even a good diamond cutter has a problem and the diamond breaks. For one cutter, the rate of breaks is .2%. Suppose now that you want to find the probability that at least 1 is broken when twelve diamond cutters are selected at random. Choose the option below that best answers how to do this question. Let X be the discrete random variable that represents the number of breaks. Assume a binomial distribution.
a. do (.998)^12 Ob)
b. do 1 – [(-998)^12] c)
c. calculate P(X=1) + P(X=2) +...+ P(X=12) using the binomial formula or an individual table in excel d)
d. calculate the P(X31) using the binomial formula or a cumulative table in excel e)

This answer is correct I got it right on khan.

Step-by-step explanation:

We plot the given vertices (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5) on the graph we get pentagon as shown below.

The given vertices are (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5).

We need to plot the given vertices on the graph.

A point in a plane contains two components where order matters! It comes in the form (x, y) where x comes first, and y comes second.

We plot the given vertices (−7.5, 0), (0,6.5), (5.5, 5.5), (6.5,0), (0, -4.5) on the graph we get pentagon as shown below.

Answer:

[tex]Range= \{1,-4,-19\}[/tex]

Step-by-step explanation:

Given

[tex]f(n) = -4n - 3[/tex]

[tex]n = \{-1,1/4,4\}[/tex] --- domain

Required

Determine the range

To do this, we simply substitute the values of n in the given expression

So, we have:

[tex]n = -1[/tex]

[tex]f(-1) = -4 * -1 - 3 =4 - 3 = 1[/tex]

[tex]n = 1/4[/tex]

[tex]f(-1) = -4 * 1/4 - 3 =-1 - 3 = -4[/tex]

[tex]n=4[/tex]

[tex]f(-1) = -4 * 4 - 3 =-16 - 3 = -19[/tex]

Hence, the range is:

[tex]Range= \{1,-4,-19\}[/tex]

Option (3)

Step-by-step explanation:

Steven has created a box plot to record the number of students who attended the science club meeting.

In a box plot, initial dot represents the minimum number and extreme point represents the maximum number.

From the graph attached,

Maximum number of students who attended the meeting are 32.

Therefore, Option (3) will be the correct option.

Answer:

x = 99°

Step-by-step explanation:

first: find the supplement to 123°:

180 - 123 = 57°

second: since all triangle interior angles total a80°:

180 - 42 - 57 = 81°

third: x = the supplement to 81°, so, x = 180 - 81 = 99°

Answer:

Cos 68

Step-by-step explanation:

Given the expression 2cos² 34° - 1, we are to expression as a single trig ratio.

Let the angle be theta

Recall that sin²theta + cos²theta = 1

sin²theta  = 1 - cos²theta ... 1

also Cos 2theta = Cos²theta - sin²theta  ... 2

Substitute 1 into 2

Cos 2theta = Cos²theta - (1-cos²theta)

Cos 2theta = Cos²theta - 1 + cos²theta

Cos 2theta = 2Cos²theta - 1

Replace theta with 34

Cos 2(34)= 2Cos²(34)- 1

Cos 68 = 2Cos²(34)- 1

Hence the single trig expression is Cos 68
