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.

[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

+ 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

Answer:

a) x + y

b) m x 7 or 7m

c) m x 3 or 3m

d) [tex]\frac{n - 3}{4}[/tex]

Step-by-step explanation:

a) the sum of x and y

- the sum most likely always means addition

b) the product of m and 7

- the product usually means multiplucation

c) the cost of 3 movie tickets at m dollars each

- so your getting 3 movie tickets at $m

the total would be m + m + m which is the same as mutiplying m by 3

d) 3 less than n, all divided by 4

- 3 less than n

less than usually means subtraction

than divided by 4

c) the cost of 3 movie tickets at m dollars each d) 3 less than n, all divided by 4

[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]

First, "the sum of" indicates that we add.

Since we're asked to find the sum of x and y, we need to add them:-

Now, the "product of" indicates that we multiply.

So we multiply m times 7, which can be written as follows:-

If we have 3 movie tickets, and each of them costs m dollars, then in order to find the cost of all 3 movie tickets, we need to find the product of the total number of tickets times the cost of one ticket:-

So we multiply 3 times m, or

Now, "3 less than n" indicates that we subtract 3 from n; this expression is divided by 4, or:-

Answer: x = -15

Step-by-step explanation:

Think PEMDAS

First, we factor the parenthesis:

-4 (x-4) = -4(x) + -4(-4)

now we are left with -4x + 16 = -44

Next is to isolate the "x":

to do this, we must subtract 16 from -44

-44 - 16 = 60

now we have -4x = 60

Now we divide both sides by -4 in order to isolate "x"

dividing -4x/-4 = x

diving 60/-4 = -15

the answer is x= -15

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.

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.
