1. What would the polynomial x + 7 – 4x^3 be written as in standard form?
yarga [219]
Hello there!

The only thing we need to do to get this polynomial in standard form is rearrange the terms!

x+7-4x^3
-4x^3+x+7 is the polynomial written in standard form. Remember to keep track of the negatives!

The GCF of the polynomial
24x^5+18x^9 is...
6x^5
Because it is the greatest term that goes into both 24x^5 AND 18x^9!
This will end up helping you factor later on.
6x^5(4+3x^4)

I really hope this helps!
Best wishes :)

What is the AREA of this figure?
elena-14-01-66 [18.8K]

Answer:

532m squared is the answer

Step-by-step explanation:

Split the shape into two shapes

one will be a square and the other one a triangle

1) since the length and the width of the square is 18m just Multiply

18x18=324m squared

2) look carefully the width of the square you split is equal to the base of the triangle, so you connect the 18 and the 8 together.

18+8=26m squared

3) Now solve the triangle since you know the height which is 16m squared.

A=lw/2

26x16=416

416 divided by 2 is 208

4) finally just Add

208+324=532m squared

Hopes this helps!

It is known that 10% of the calculators shipped from a particular factory are defective. In a random sample of ten calculators,
umka2103 [35]

Answer:

0.7361

Step-by-step explanation:

In this question we have

number to be 10

Then we have a probability of 10% = 0.10

We have q = 1-p

= 1-0.10 = 0.90

Then the probability of not more than 1 being defective:

P(x=0) + p(x= 1)

(10C0 x 0.1⁰ x 0.9^10-0)+(10C1 x 0.1¹ x 0.9^10-1)

= 1 x1 x0.3487 + 10 x 0.1 x 0.3874

= 0.3487 + 0.3874

= 0.7361

This is the the required probability and this answers the question.

probability = 10 percent = 0.1

q= 1- 10percent = 90% = 0.9

n = 4

To get the required probabiltiy for this question is

P(not greater than one is defective )=P(x=0)+P(x=1)

= 4C0x(0.1)⁰x(0.9)⁴+4C1x(0.1)¹x(0.9)³

= 0.9477

The required probability is 0.9477

How do I find the value of x
Kaylis [27]

Answer:

The angles inside a hexagon add up to 720.

105 + 88 + 142 + 140 + 124 + x = 720

720 - (105 + 88 + 142 + 140 + 124)  = x

720 - 599 = x

<h2>x = 121</h2>
