For the past 40 days, Naomi has been recording the number of customers at her restaurant between 10:00 a.m. and 11:00 a.m. Durin

g that hour, there have been fewer than 20 customers on 25 out of the 40 days.
What is the experimental probability there will be **20 or more customers** on the forty-first day? Include it as fraction, decimal and percent.

Answer:

the experimental probability for 20 or more customersis 37.5%

Step-by-step explanation:

Given that

The recording of the customers would be in between 10:00 AM to 11:00 PM

In this, they have been fewer than 20 customers on 20 out of the 40 days

We need to find out the experimental probability for 20 or more customers

So,

= (40 - 25) ÷ (40)

= 15 ÷ 40

= 37.5%

Hence, the experimental probability for 20 or more customers is 37.5%

Answer:

a difference of squares

Step-by-step explanation:

Let's write down the expression:

$(a^2)^2 -(b^2)^2$

we can see that this expression is one of the form $x^2 -y^2$ which is the general expression of a difference of squares.

To be more specific and to see why we say this, let's make $x=a^2$ and $y=b^2$

Now, if we substitute this in the general formula, we get:

$x^2 -y^2 =(a^2)^2 -(b^2)^2$

Thus, this expression is a difference of squares.

Graph a triangle on the coordinate plane. Choose 1 transformation (reflection, rotation,

BlackZzzverrR [31]

Answer:

The answer in the procedure

Step-by-step explanation:

we have the right triangle ABC

The pre-image coordinates are

$A(0,0),B(0,3),C(4,0)$

The transformation to use is the translation

The rule of the translation is

$(x,y)-----> (x+10,y)$

That means----> The translation is 10 units to the right

The image coordinates are

Applying the rule of the translation

$A'(0+10,0)=A'(10,0)$

$B'(0+10,3)=B'(10,3)$

$C'(4+10,0)=C'(14,0)$

using a graphing tool

What is the equation of the line that passes through the point (4.11) and is perpendicular to the line with the following equati

Klio2033 [76]

Answer:

$y = x +7$

Step-by-step explanation:

Given

$Point\ (x_1,y_1) = (4,11)$

Perpendicular to $y = -x + 14$

Required

Determine the line equation

An equation has the form

$y = mx + b$

Where

$m = slope$

By comparison with $y = -x + 14$

$m = -1$

Because the line is perpendicular to $y = -x + 14$ , the following relationship exists

$m_1 = \frac{-1}{m}$ i.e. the condition for perpendicularity

Where m1 is the slope of the equation that passes through $Point\ (x_1,y_1) = (4,11)$

So, we have:

$m_1 = \frac{-1}{-1}$

$m_1 = 1$

The line equation is then calculated using:

$y - y_1 = m_1(x - x_1)$

Where

$m_1 = 1$

$Point\ (x_1,y_1) = (4,11)$

So, we have:

$y - 11 = 1(x - 4)$

$y - 11 = x - 4$

Add 11 to both sides

$y - 11+11 = x - 4+11$

$y = x - 4+11$

$y = x +7$
