Using the vertex of the quadratic equation, it is found that the value of b is of -9.

A quadratic equation is modeled by:

[tex]y = ax^2 + bx + c[/tex]

The vertex is given by:

[tex](x_v, y_v)[/tex]

In which:

[tex]x_v = -\frac{b}{2a}[/tex]

[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]

The axis of symmetry is [tex]x = x_v = -\frac{b}{2a}[/tex].

Considering the coefficient a, we have that:

In this problem, we have that the function is defined as follows:

[tex]f(x) = 3x^2 + bx + 4[/tex]

We have that [tex]a = 3, x_v = \frac{3}{2}[/tex], hence the value of b is found as follows:

[tex]x = -\frac{b}{2a}[/tex]

[tex]\frac{3}{2} = -\frac{b}{6}[/tex]

b = -6 x 3/2

b = -9.

Answer:

[tex]\boxed{\sf \bold{x = -8}}[/tex]

Explanation:

3(2x+2)= 4x -10

apply distributive method: a(b+c) = ab + ac

3(2x) + 3(2) = 4x - 10

multiply

6x + 6 = 4x - 10

subtract both sides by 4x

6x + 6 - 4x = 4x - 10 -4x

simplify

2x + 6 = -10

subtract both sides by 6

2x + 6 -6 = -10 -6

simplify

2x = -16

divide both sides by 2

x = -8

Step-by-step explanation:

6 x 16.98 = 101.88

+ 6 x 13.79 = 184.62

300 - 184.62 = 115.38

Answer:

$115.38

Step-by-step explanation:

6×$16.98=$101.88=cost of basketballs

6×$13.79=$82.74=cost of soccer balls

cost of basketballs + cost of soccer balls = total cost

$101.88+$82.74=$184.62

money to purchase - total cost = leftover money

$300.00 - $184.62 = $115.38

Answer: [tex]128ft^2[/tex]

Step-by-step explanation:

If the 16ft is the sum for both sides already means the first length is 8ft and also the second length is 8ft. then since there are 32 ft more left, you divide it by two since there were two widths left, the values of the two widths are 16ft each. so the sum of the two widths is 32ft. and that's the final answer.

[tex]Length=16[/tex]

[tex]Perimeter=48[/tex]

[tex]Using ~the ~formulas:[/tex]

Step-by-step explanation: as the second one is bigger than the first one .

Using the binomial distribution, it is found that there is a 0.864 = 86.4% probability that at most 5 seniors will attend the prom.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem, we have that:

The probability that at most 5 seniors will attend the prom is given by:

[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]

In which:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{20,0}.(0.18)^{0}.(0.82)^{20} = 0.0189[/tex]

[tex]P(X = 1) = C_{20,1}.(0.18)^{1}.(0.82)^{19} = 0.0829[/tex]

[tex]P(X = 2) = C_{20,2}.(0.18)^{2}.(0.82)^{18} = 0.1730[/tex]

[tex]P(X = 3) = C_{20,3}.(0.18)^{3}.(0.82)^{17} = 0.2278[/tex]

[tex]P(X = 4) = C_{20,4}.(0.18)^{4}.(0.82)^{16} = 0.2125[/tex]

[tex]P(X = 5) = C_{20,5}.(0.18)^{5}.(0.82)^{15} = 0.1493[/tex]

[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.0189 + 0.0829 + 0.1730 + 0.2278 + 0.2125 + 0.1493 = 0.864[/tex]

0.864 = 86.4% probability that at most 5 seniors will attend the prom.
