The following table provides a probability distribution for the random variable y. Y f(y) 1 0. 20 5 0. 30 6 0. 40 9 0. 10 (a) co
Vitek1552 [10]

The probability distribution table is used to represent individual probabilities

The value of E(y) is 5.0

<h3>How to compute e(y)?</h3>

The value of e(y) is calculated using the following expected value formula

E(y) = \sum y * P(y)

So, we have:

E(y) = 1 * 0.20 + 5 * 0.30 + 6 * 0.40 + 9 * 0.10

Evaluate

E(y) = 5.0

Hence, the value of E(y) is 5.0

A trapezoid has base lengths of 5 meters and 3.5 meters. If the height of the trapezoid is 4 meters, what is the area of the tra
aev [14]

Answer:

17 m² or 17 square meters

Step-by-step explanation:

A trapezoid has base lengths of 5 meters and 3.5 meters. If the height of the trapezoid is 4 meters, what is the area of the trapezoid?

Area of a trapezoid =1/2(b1 + b2)h

Where

b1 = First base length = 5m

b2 = Second base length = 3.5 m

Height = 4m

= 1/2(5m + 3.5m) × 4m

= 1/2(8.5m) × 4m

= 1/2 × 8.5m × 4m

= 17 m²

Therefore, the area of the trapezoid is 17 m² or 17 square meters

(Squreroot x+2)(squreoot x-2)=0
yuradex [85]

Answer:

\boxed{ \ x = 2  \ or \  x = -2 \ }

Step-by-step explanation:

I understand that you want to solve this equation

\sqrt{x+2}\sqrt{x-2}=0

<=>

\sqrt{(x+2)(x-2)}=0

<=>

(x+2)(x-2)=0

<=>

x = 2 or x = -2

hope this helps

if your question is (\sqrt{x}+2)(\sqrt{x}-2) = 0

then this is (\sqrt{x})^2-4 = 0\\ x = 4

Which of the following equations has only one solution? x2 + 4x + 4 = 0 x2 + x = 0 x2 - 1 = 0
Nady [450]
<span>you can solve all quadratic equations using this method:
---
x^2 + 4x + 4 = 0
---
the above quadratic equation is in standard form, with a=1, b=4, and c=4
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 4 4
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
this quadratic has ONE real root (the x-intercept), which is:
x = -2
x = -2
---
---
---
---
x^2 + x = 0
---
the above quadratic equation is in standard form, with a=1, b=1, and c=0</span>
