(CO 3) On average, the parts from a supplier have a mean of 97.5 inches and a standard deviation of 6.1 inches. Find the probabi
ololo11 [35]

Answer:

C. Probability is 0.90, which is inconsistent with the Empirical Rule.

Step-by-step explanation:

We have been given that on average, the parts from a supplier have a mean of 97.5 inches and a standard deviation of 6.1 inches.

First of all, we will find z-score corresponding to 87.5 and 107.5 respectively as:

z=\frac{x-\mu}{\sigma}

z=\frac{87.5-97.5}{6.1}

z=\frac{-10}{6.1}

z=-1.6393

z\approx-1.64

z=\frac{x-\mu}{\sigma}

z=\frac{107.5-97.5}{6.1}

z=\frac{10}{6.1}

z=1.6393

z\approx 1.64

Now, we need to find the probability P(-1.64.

Using property P(a, we will get:

P(-1.64

From normal distribution table, we will get:

P(-1.64

P(-1.64

P(-1.64

Since the probability is 0.90, which is inconsistent with the Empirical Rule, therefore, option C is the correct choice.

What is the factored form of 3x + 21x-24?
anastassius [24]

Answer:

factorize form of the equation is  24(x-1)=0  , where  x=1

Step-by-step explanation:

Given Equation:

                        3x + 21x-24=0    

  Adding the terms of 'x' and taking constants on the other side.                        

                    24x-24=0

The sign of the constant will change on changing the side of it.                

                         24x=24

                           x=\frac{24}{24}

                            x=1

So, the value of  'x' is 1

The factorized form of the equation can be made by taking the common value from the equation i.e  

                      24x-24=0\\

                   24(x-1)=0

Please help:
Fudgin [204]

Answer:

\angle 1 =47^o\\\angle 2 = 133^o\\\angle 4 = 133^o

Step-by-step explanation:

Notice that angles <1 and <3  are opposed by the vertex, which makes them of equal measure, therefore, <1 = 47 degrees.

Notice as well that angles <1 and <2 combine into a straight line, therefore, they are supplementary angles whose addition gives 180 degrees then we can find the value of angle <2 via:

\angle 1 + \angle 2 = 180^o\\47^o + \angle 2=180^o\\\angle 2 = 180^o-47^o\\\angle 2 =133^o

And finally, angle <4 is opposite through the vertex to angle <2, and therefore they must have the same measure. So, <4 = 133 degrees.
