Express the polynomial −4p + 3p + 2p2 in standard form and then classify it.

1 answer:

6 0

The standard form of the polynomial function will be found as follows:
-4p+3p+2p2
simplifying the above we get:
-p+2p^2
this can be written as:
2p^2-p+0

this is a quadratic equation, which has a form of ax^2+bx+c
from our polynomial
a=2, b=-1, c=0

Estimates show that there are 1.4x10^8 pet fish and 9.4x10^6 pet reptiles in the United States. How many pet fish and reptile pe

azamat

Answer:

There are total number of pet fish and reptile pets are $1.49\times 10^8$ .

Step-by-step explanation:

Number of pet fish are $1.4\times 10^8$ and the number of pet reptiles are $9.4\times 10^6$ .

It is required to find the total number of pet fish and reptile pets in the United States. It can be done by simply adding the above numbers such that total numbers are given by :

$T=1.4\times10^{8}+9.4\times10^{6}\\\\T=149400000\\\\T=1.49\times 10^8$

So, there are total number of pet fish and reptile pets are $1.49\times 10^8$ .

The average watermelon weighs 8 lbs with a standard deviation of 1.5. Find the probability that a watermelon will weigh between

Andrew [12]

Answer:

The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.

P(6.8 ≤X≤9.3) = 0.5932

Step-by-step explanation:

Step 1:-

by using normal distribution find the areas of given x₁ and x₂

Given The average watermelon weighs 8 lbs

μ = 8

standard deviation σ = 1.5

I) when x₁ = 6.8lbs and μ = 8 and σ = 1.5

$z_{1} = \frac{x_{1} -mean}{S.D} = \frac{6.8-8}{1.5} = - 0.8$

ii) when x₂ = 9.3 lbs and μ = 8 and σ = 1.5

$z_{2} = \frac{x_{2} -mean}{S.D} = \frac{9.3-8}{1.5} = 0.866>0$

<u>Step2</u>:-

The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.

P(6.8 ≤X≤9.3) = A(z₂) - A(-z₁)

= A(0.866) - A(-0.8)

= A(0.866)+ A(0.8)

check below normal table

= 0.3051 + 0.2881

= 0.5932

<u>Conclusion</u>:-

The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.

P(6.8 ≤X≤9.3) = 0.5932

Help please I beg of the

Anika [276]

Answer:

1 would be on 1.4 so before 1.5 on the line

2 would be on around 4.1 so after 4.0 by a little

3 would be on 3.3 so kind of in the middle of 3.0 and 3.5

4 would be on 2.8 so before 3.0

5 is on 2.2 so a little after 2.0

6 would be just a little more than 5 around 5.09

11 is E

12 is A

13 is D

14 is C

15 is B

16 is B

17 is A

18 is D

19 is C

20 is E

All you have to do is find the square root through a calculator then round your answer and estimate where it would go on the line. Hope this helped
