What is the value of the expression below when x=3<br> 10x²- 7x + 10

Andreas93 [3]

Answer: 79

Concept:

Here, we need to understand the idea of evaluation.

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

<u>Given information</u>

10x² - 7x + 10

x = 3

<u>Substitute the value into the expression</u>

= 10 (3)² - 7 (3) + 10

<u>Simplify by multiplication</u>

= 10 (9) - 21 + 10

= 90 - 21 + 10

<u>Simplify by subtraction</u>

= 69 + 10

<u>Simplify by addition</u>

= 79

Hope this helps!! :)

(-r-5)-(-2r-4) help me solve pls lol

vaieri [72.5K]

<h3>answer:</h3>

$r - 1$

<h3>Step by step explanation:</h3>

<h3> Step 1: Distribute</h3>

$( - r - 5) - ( - 2r - 4) \\ ( - r - 5) + 2r + 4$

<h3>Step 2: Eliminate redundant parenthesis</h3>

$( - r - 5) + 2r + 4 \\ - r - 5 + 2r + 4$

<h3>Step 3: Add numbers</h3>

$- 3 \purple{ - 5} + 2r + \purple{4} \\ - r \purple{ - 1} + 2r$

<h3>Step 4:Combine like terms </h3>

$\purple{ - r } - 1 + \purple{2r} \\ \purple{1r} - 1$

<h3>Step 5:Multiply by 1</h3>

$1r - 1 \\ r - 1$

Hopefully it's help

Suppose that the probabilities of a customer purchasing 0, 1, or 2 books at a book store are 0.20.2, 0.30.3, and 0.50.5, res

PIT_PIT [208]

Answer:

0.78

Step-by-step explanation:

We have the next probability distribution:

X P(X)

0 0.2

1 0.3

2 0.5

As we can see when we add all the probabilites the result is 1. Now calculating the mean we have:

$mean=\mu=(0\times0.2)+(1\times 0.3)+(2\times 0.5)=0+0.3+1=1.3$

The standard deviation is:

$\sigma=\sqrt{\sum(x-\mu)^{2}(P(x))}$

Then using the data that we have:

$\sigma=\sqrt{\sum(x-\mu)^{2}(P(x))}\\\sigma=\sqrt{(0-1.3)^{2}(0.2)+(1-1.3)^{2}(0.3)+(2-1.3)^{2}(0.5)}\\\\\sigma=\sqrt{(-1.3)^{2}(0.2)+(-0.3)^{2}(0.3)+(0.7)^{2}(0.5)}\\\\\sigma=\sqrt{(1.69)(0.2)+(0.09)(0.3)+(0.49)(0.5)}\\\\\sigma=\sqrt{0.338+0.027+0.245}\\\\\sigma=\sqrt{0.61}\\\\\sigma=0.78\\$

Then the standard deviation is 0.78
