Question 1

Dima020 [189]

Answer:

87.5% probability that it is NOT number 2.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

Any ball not numbered 2. So 1,3,4,5,6,7,8. So 7 desired outcomes, which means that $D = 7$

Total outcomes:

All balls, which are 8. So $T = 8$

Probability:

$p = \frac{D}{T} = \frac{7}{8} = 0.875$

87.5% probability that it is NOT number 2.

Find the product.<br> a 4(3a2 - 2a + 1)<br><br> (typed answers not selection)

Rus_ich [418]

Answer:

$3a^6-2a^5+a^4$

Step-by-step explanation:

Use the rules of indices to find the product.

One of the rules is that when we multiply indices that have the same base we add the powers. For example:

$x^4 * x^5 = x^9$

So to work out $a^4(3a^2-2a+1)$ we need to follow this rule.

Let's expand the bracket:

$a^4(3a^2-2a+1) = (a^4)(3a^2)+(a^4)(-2a)+(a^4)(1)$

Let's simplify keeping in mind the rule we know.

$(a^4)(3a^2)=3a^6$

$(a^4)(-2a) = -2a^5$ - remember that $a = a^1$

$(a^4)(1) = a^4$

PLEASE HELP IF U CAN!

12345 [234]

Answer:

$x = 8$

Step-by-step explanation:

Given

The attached triangle

Required

Determine the value of x

x represents the height of the triangle.

And the area of a triangle is calculated as:

$Area = \frac{1}{2} * Base * Height$

Where

$Base = 4$

$Area = 16$

$Height = x$

The expression becomes

$16 = \frac{1}{2} * 4* x$

$16 = 2* x$

$16 = 2x$

Divide through by 2

$8 = x$

$x = 8$
