What is the correlatio. coefficient with (2.1)(3.2)(6.8)(7.3)(11.2)(12.6)(13.4)(15.9)

Answers

Answer 1

Answer:

we know that

The correlation coefficient is a number between $-1$ and $+1$ that represent the linear dependence of two variables or sets of data

Using a Excel tool (CORREL function)

see the attached table

The answer is

The correlation coefficient is $r=0.56$

Electrons and protons are particles in an atom with equal but opposite charges. Electrons have a negative charge and protons have a positive charge. What is the charge amount of an atom with 2 more electrons than protons?

Answers

Answer:

$-3.2\cdot 10^(-19)C$

Step-by-step explanation:

- Protons are positively charged particles contained in the nucleus of the atom. They have a charge of $q_p=+1.6\cdot 10^(-19)C$

- Electrons are negatively charged particles orbiting around the nucleus of the atom. They have a charge of $q_e = -1.6\cdot 10^(-19)C$

For a neutral atom, the number of protons is equal to the number of electrons, so the total charge of a neutral atom is:

$Q=Nq_p + Nq_e = N(q_p+q_e)=N(+1.6\cdot 10^(-19)-1.6\cdot 10^(-19))=0$

In this problem, we have an atom having an excess of 2 electrons, i.e. it has 2 more electrons than protons.

Therefore, the charge of this atom will be:

$Q=0+2q_e$

and substittuing, we find

$Q=2(-1.6\cdot 10^(-19))=-3.2\cdot 10^(-19)C$

Answers

Answer:

A = 139°

G = 41°

Step-by-step explanation:

Measure of D = 139°

Given that, X|| Y

Then

Alternate angle theorem (Remember that "Z" Theorem?)

< D = < H (By simple theorem above![Alt <s])

<H = 139°

Also <H = <A[Vertically opposite angles]

<A = 139°

We know by co-interior < theorem,[X||Y]

<H +<G = 180°
<G = 180° - <H = 180° - 139°
<G = 41°

A = 139 degrees
G = 41 degrees

javier bought 48 sport cards at a yard sale. of the cards 3/8 were baseball cards. hoe many cards were baseball cards?

Answers

3/8·48=3·6=18

Answer: B

18 cards were baseball cards.

since 6 can go into 48 8 times, you do 6 x3 which is 18

Karen measured an Orange and a tangerine. The orange Weighed 3/4 pounds. The tangerine weighed 4/6 pounds.which was heavier? Write an inequality to show how their weights compare

Answers

Solutions

Karen measured an Orange and a tangerine. The orange Weighed 3/4 pounds. The tangerine weighed 4/6 pounds. To solve the problem we first have to make the denominators common. To make the denominators common you have to multiply by the GCF ( greatest common factor).

4/6 and 3/4's common denominator is 24

$(4)/(6) = (16)/(24)$

$(3)/(4) = (18)/(24)$

18/24>16/24, the orange is heavier

18/24>16/24, the orange is heavier

a prism and a pyramid are side by side. they have the same height and same base are. the volume of the prism would be ? times the volume of the pyramid?

Answers

Answer:

The volume of the prism is 3 times the volume of the cone

Step-by-step explanation:

step 1

we know that

The area of the prism is given by the formula

$V_p=Bh$ ----> equation A

where

B is the area of the circular base

h is the height of the prism

step 2

The area of the cone is given by the formula

$V_c=(1)/(3) Bh$ ----> equation B

where

B is the area of the circular base

h is the height of the cone

In this problem we have that they have the same height and same base area

substitute equation A in equation B

$V_c=(1)/(3) V_p$

solve for V_p

$V_p=3V_c$

therefore

The volume of the prism is 3 times the volume of the cone

Emil bought a camera for $268.26, including tax. He made a down payment of $12.00 and paid the balance in 6 equal monthly payments. What was Emil's monthly payment for this camera?

Answers

Firstly, subtract the cost that Emil has already put down;
268.26-12= 256.26
Then divide by the monthly installments
256.26/ 6= 42.71
Therefore, Emil pays $42.71 per month
Hope this helps :)
