Answer:

  x = 3 1/2

Step-by-step explanation:

You could simplify the given equation first, then solve the resulting 2-step linear equation. It might work better to undo the operations done to the variable.

<h3>Solution</h3>

  (5 1/6 -x)(2.7) -5 3/4 = -1 1/4 . . . . . given

  (5 1/6) -x)(2.7) = 4 1/2 . . . . . . . add 5 3/4 to both sides

  (5 1/6 -x) = 4.5/2.7 = 5/3 . . . divide by 2.7

  31/6 -10/6 = x . . . . . . . . . . add x-5/3, use common denominators

  21/6 = x = 7/2

  x = 3 1/2

In a busy coffee shop, which is a member of an international chain of coffee shops, 40% of customers order a pastry in addition
trasher [3.6K]

Answer:

0.7553

Step-by-step explanation:

Given that in a busy coffee shop, which is a member of an international chain of coffee shops, 40% of customers order a pastry in addition to their drink.

Hence for 20 customers  selected at random during one business day,  x the no of customers who did not order a pastry with their drink is binomial since each customer is independent and there are only two outcomes.

X is binomial with n =20 and p = 1-0.4 = 0.60

q = 0.4

the probability that at least 11 of them did not order a pastry with their drink

=P(x\geq 11) =1-0.2447\\= 0.7553

Note that binomial prob

P(X=x) = 20Cx (0.6)^x (0.4)^{20-x}

Line g is shown on the graph.
alisha [4.7K]

The linear equation that defines the line G can be written as:

y = -(1/3)*x + 5

<h3>How to get the equation of the line G?</h3>

A general linear equation written in the slope-intercept form is:

y = a*x + b

Where a and b are real numbers, a is the slope and b is the y-intercept.

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

In this case we know that the line passes through (-3, 6) and (0, 5), then the slope is:

a = (5 - 6)/(0 - (-3)) = -1/3

The linear equation is something like:

y = (-1/3)*x + b

We know that it passes through (0, 5), then:

5 = (-1/3)*0 + b

5 = b

We conclude that the linear equation can be written as:

y = -(1/3)*x + 5
