The probability the next customer pays using a debit card based on the last three weeks is 30% or 0.3.

<h3>What is a probability?</h3>

This is the chance or likelood for an event to occur. For example, if in a city it has snowed every year on December 25th, there is a high probability it will snow this year and in the next years.

<h3>How to calcuate the probability?</h3>

Total of a specific outcome/ total of outcomes

Based on this, let's calculate the probability the next customer pays using the debit card:

  • Total that pay with debit card: 21 customers
  • Total of customers: 70 customers
  • 21/ 70 =0.3 or 30%

If x^2=20 what is the value of x will give brainliest for answer
Schach [20]

Answer:

x² - 20 = 0

Using the quadratic formula

x =  \frac{ - b± \sqrt{( {b})^{2} - 4ac } }{2a}

a = 1 b = 0 c = -20

So we have

x =  \frac{ - 0 ±  \sqrt{ {0}^{2}  - 4(1)( -20)} }{2(1)}  \\  \\ x =  \frac{± \sqrt{80} }{2}  \\  \\ x =  \frac{±4 \sqrt{5} }{2}  \\  \\  \\ x = ±2 \sqrt{5}  \\  \\  \\ x = 2 \sqrt{5}  \:  \:  \: or \:  \:  \: x =  - 2 \sqrt{5}

Hope this helps you.

Help me PLease<br><br><br><br> also explain how to do it

❥\Large\pmb{ \underline {\tt Answer}}

So we can only find x if other two angles of triangle is given.

In angle B as u can see boxed shape angle is there then it probably means it's a 90° angle.

We know sum of angles of triangle = 180°

{Reson :-

There's a formula to fund sum of angles of figure

  • (n-2) × 180
  • (3 -2) × 180
  • 1 × 180
  • 180°

}

Now Let's proceed

\boxed{ \rm Side_1+Side_2+Side_3 = 180\degree}

Fill all the given values

\dashrightarrow \tt 90 \degree + 55 \degree + c = 180 \degree

\\  \\

\dashrightarrow \tt 145\degree + c = 180 \degree

\\  \\

\dashrightarrow \tt  c = 180  \degree - 145\degree

\\  \\

\dashrightarrow \tt  c = 35\degree

\\  \\

Value of x = 35°

What is the surface area of a cylinder that has the following measurements? area of each base: 50.24 ft2 area of lateral surface
irinina [24]

Answer:

TSA = 175.84 ft²

Step-by-step explanation:

We are given;

Lateral surface area; A_L = 75.36 ft²

Area of base; A_b = 50.24 ft²

Height of cylinder; h = 3ft

Formula for total surface area of Cylinder is;

TSA = 2πr² + 2πrh

Now, lateral surface area is given by the formula; A_L = 2πrh

Area of base is given by the formula;

A_b = πr²

Thus, let's apply these 2 formulas to the formula for total surface area;

TSA = 2(Area of base) + Lateral surface area

TSA = (2 * 50.24) + 75.36

TSA = 175.84 ft²
