Answer:

I think option 3rd is correct the vertices.

Step-by-step explanation:

B is joining the D and C together.  

The expression that is equal to 3B - C in standard form is 2.0 × 10¹

From the question, we are to determine the value of the expression

The given expression is

3B - C

From the given information,

B = p + 6

and

C = 3p - 2

Putting the the values of  B and C into the expression, we get

3B - C = 3(p + 6) - (3p -2)

= 3p + 18 -3p + 2

= 3p - 3p + 18 + 2

= 20

= 2.0 × 10¹

Hence, the expression that is equal to 3B - C in standard form is 2.0 × 10¹

Answer:

[tex]T_n =-\frac{8}{3} (-3)^{n}[/tex]

Step-by-step explanation:

Given

[tex]Sequence: 8, -24, 72[/tex]

Required

Determine the n term

The above sequence is geometric. So, we calculate the common ratio first:

[tex]r = \frac{T_2}{T_1}[/tex]

[tex]r = \frac{-24}{8}[/tex]

[tex]r = -3[/tex]

The equation is then calculated using:

[tex]T_n = ar^{n-1}[/tex]

Where

[tex]a = T_1 = 8[/tex]

and

[tex]r = -3[/tex]

The equation becomes:

[tex]T_n =8 * (-3)^{n-1}[/tex]

Apply law of indices:

[tex]T_n =8 * (-3)^{n} * (-3)^{-1}[/tex]

[tex]T_n =8 * (-3)^{n} * \frac{1}{-3}[/tex]

[tex]T_n =-8 * (-3)^{n} * \frac{1}{3}[/tex]

[tex]T_n =-\frac{8}{3} * (-3)^{n}[/tex]

[tex]T_n =-\frac{8}{3} (-3)^{n}[/tex]

Answer:

0.4198 = 41.98% probability that he or she has a basic model

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Extended warranty

Event B: Basic model

Probability of extended warranty:

34% of 50%(basic model)

47% of 100 - 50 = 50%(deluxe model). So

[tex]P(A) = 0.34*0.5 + 0.47*0.5 = 0.405[/tex]

Intersection of events A and B:

34% of 50%(basic model with extended warranty). So

[tex]P(A \cap B) = 0.34*0.5 = 0.17[/tex]

How likely is it that he or she has a basic model

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.17}{0.405} = 0.4198[/tex]

0.4198 = 41.98% probability that he or she has a basic model

Answer:

c.

Step-by-step explanation:

The pattern is supposed to be -4.

Gianna has 76 stamps left after 6 packages and pattern of decreasing stamps can be calculated as 100, 96, 92, 88, 84, 80, 76. Hence option c is correct

Gianna uses 100 stamps each day for her business. If she begins each day with 100 stamps, and after each package that is shipped has 4 less stamps,

In mathematics it deals with numbers of operations according to the statements.

As per question, after each package that is shipped has 4 less stamps.
Now,  for nth term of an arithmetic progression.
nth term = a + nd
Here, we have a = 100, d = -4 and  n = 6
So after 6th package shipped the number of stamps left.
= 100 - 6 x 4
= 76
And pattern of decreasing stamps can be calculated as 100, 96,92,88,84,80,76.

Thus, Gianna has 76 stamps left after 6 packages and pattern of decreasing stamps can be calculated as 100, 96,92,88,84,80,76.

3x4 is 12 and then you subtract them from each 9ther

number 4 is the slope

Answer:

the Y intercept of the line would be -12

Step-by-step explanation:

in a linear equation like that for example, any equation that is formed as: y=mx+b would always have B as it's y intercept, and since your equation is y=-3x-12 than your y intercept would be -12!
