Answer:

m = 1.8

Step-by-step explanation:

Given data is as follows :

x 1 2 3 4 5 6

f 1 4 7 m 6 3​

We need to find the value of m if the mean of the data is 3.8.

Mean = sum of observations/no. of observations

So,

3.8=\dfrac{1+4+7+m+6+3}{6}\\\\22.8=21+m\\\\22.8-21=m\\\\m=1.8

So, the value of m is equal to 1.8.

The volume of a rectangular prism is given by the formula V=lwh, where I is the length of the prism, w is the width, and h is th
antoniya [11.8K]

Answer:

The answer is 6x^{3} +39x^{2}+54x

Step-by-step explanation:

Volume of the rectangular prism = Length * Width * Height

Length (l) = x+2

Width (w) = 3x

Height (h) = 2x+9

By substituting these values to the equation above,

Volume of the rectangular prism = (x+2)*3x*(2x+9)

                                                      =(3x^{2} +6x)*(2x+9)

                                                      =6x^{3} +27x^{2} +12x^{2} +54x

                                                      =6x^{3} +39x^{2}+54x

Therefore,

The answer is 6x^{3} +39x^{2}+54x

Discuss the validity of the following statement. If the statement is always​ true, explain why. If​ not, give a counterexample.
Zigmanuir [339]

Answer:

P(E \cup F)=P(E)+P(F).

Step-by-step explanation:

Given the statement

If P(E)+P(F)=P(E \cup F)+P(E \cap F), then E and F are mutually exclusive events.

If two events are mutually exclusive, they have no elements in common. Thus, P(E∩F)=0.

Therefore, the statement is always true as P(E∩F)=0

For mutually exclusive events:

P(E \cup F)=P(E)+P(F).
