Answer:

The correct answer option C.

Step-by-step explanation:

Let x be the number of coupons issued.

Let y be the number of the pizzas sold.

The given equation:

$y=3.4x+43$

This given equation of an straight line.

Number of pizzas when no coupons were issued.

$y=3.4x+43=3.4\times 0+43=43$

43 number of pizzas were sold in one night.

Hence, the correct answer option C.

Answer:

<em>The average number of pizzas sold in one night if no coupons are issued is </em><em>43.</em>

Step-by-step explanation:

In the scatter plot the average number of pizzas sold is represented on x and number of coupons issued is represented on y.

The trend line of this linear model is $y = 3.4x + 43$

So, when no coupons are issued then the value of x becomes 0, then putting the value of x in the equation,

$\Rightarrow y=3.4(0)+43$

$\Rightarrow y=0+43$

$\Rightarrow y=43$

Therefore, the average number of pizzas sold in one night if no coupons are issued is 43.

Consider the problem of finding the line of symmetry and vertex of the quadratic equation f(x) =x^2-8x+15 What is the error in t

Jet001 [13]

We are given the quadratic:

$f(x)=x^2-8x+15$ , with a=1, b=-8, c=15.

We know that the x-coordinate of the vertex, which is the point where the line of symmetry passes through is

$\displaystyle{ -\frac{b}{2a}$ .

Thus, the x-coordinate of the vertex is $-\frac{b}{2a} =-\frac{-8}{2\cdot1}= \frac{8}{2}=4$ .

Thus, the line of symmetry is x=4.

Answer: <span>B. The line of symmetry should have been 4 instead of –4. </span>

for the sequence, describe the pattern, write the next term, and write a rule for the nth term 1.) 2,4,8,16 2.)1,8,27,64 3.)1/1,

Ratling [72]

1. Powers of 2 ( $2^1=2,\,2^2=4,\,2^3=8,\,2^4=16,\ldots$ ).

Next term = $2^5=\boxed{32}$

$\boxed{a_n=2^n}$

2. Cube numbers ( $1^3=1,\,2^3=8,\,3^3=27,\,4^3=64,\ldots$ )

Next term = $5^3=\boxed{125}$

$\boxed{a_n=n^3}$

3. Reciprocals of the square numbers ( $\dfrac{1}{1^2}=\dfrac{1}{1},\,\dfrac{1}{2^2}=\dfrac{1}{4},\,\dfrac{1}{3^2}=\dfrac{1}{9},\,\dfrac{1}{4^2}=\dfrac{1}{16},\ldots$

Next term = $\dfrac{1}{5^2}=\boxed{\dfrac{1}{25}}$

$\boxed{a_n=\frac{1}{n^2}}$

4. Numbers 4, 5, 6, 7,... divided by 3.

Next term = $\dfrac{8}{3}$

$\boxed{a_n=\dfrac{n+3}{3}}$

5. Odd numbers from 3.

Next term = 11

$\boxed{a_n=2n+1}$
