Answer:

+6 charge and −6 charge

Step-by-step explanation:

In this problem, we need to find two charges that have a sum of 0.

In option (d), both charges have the same magnitude. But they have opposite charges.

Sum means to add up charges i.e.

+6 charge +(-6) charge = 0 (they have opposite charges)

Hence, the correct option is (d).

Answer:

0.5

Step-by-step explanation:

first you must solve addition and subtraction, to find x you must do the opposite of what it says

you must add 5 from both sides

10x -5 = 0

     +5 = +5

 then you must solve multiplication and division, for example here it says that 10 is being multiplied with x so you must do division  

you must divide 10 to both sides

10x =5

10/10 = 5/10          

after dividing 5 by 10 it will give you 0.5

so the check is

10x . 0.5 - 5 = 0

1) mean:

[tex] \frac{5 + 3 + 2 + 6 + 5 + 2 + 5}{7} = \frac{28}{7} = 4[/tex]

median:

*arrange the numbers in ascending order and choose the number at the centre

2, 2, 3, 5, 5, 5, 6

= 5

mode:

*the number that occurs most often

= 5

range:

*highest value - lowest value

= 6-2

=4

2) mean:

[tex] \frac{10 + 10 + 12 + 12 + 15 + 22 + 24}{7} = \frac{105}{7} = 15[/tex]

median

10, 10, 12, 12, 15, 22, 24

=12

mode = 10 and 12

range = 24-10

= 14

3) mean:

[tex] \frac{14 + 9 + 20 + 5 + 17 + 13}{6} = \frac{78}{6} = 13[/tex]

median:

5, 9, 13, 14, 17, 20

*since there are 2 numbers at the centre, you need to add both numbers and divide it by 2 to get the median

[tex] \frac{13 + 14}{2} = 13.5[/tex]

mode:

no mode as all number occurs once only

range = 20-5

= 15

4) mean:

[tex] \frac{21 + 15 + 16 + 25 + 13 + 18}{6} = \frac{108}{6} = 18[/tex]

median:

13, 15, 16, 18, 21, 25

[tex] \frac{16 + 18}{2} = 17[/tex]

mode:

no mode

range = 25-13

= 12

5) mean:

[tex] \frac{20 + 17 + 10 + 31 + 25 + 18 + 12}{7} = \frac{133}{7} = 19[/tex]

median:

10, 12, 17, 18, 20, 25, 31

= 18

Answer:

Interest = $1897.09               Account Balance = $4397.09

Step-by-step explanation:

2500 x 1.019 = $4397.09 = Account Balance

4397.09 - 2500 = $1897.09  = Interest

The interest will the customer earn in 30 years is $1350, the account balance be after 30 years is $3850 and the customer earn $1350 interest.

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time peroid.

In the given that new bank customer with $2,500 wants to open a money market account. The bank is offering a simple interest rate of 1.8%.

So, the Principal Amout(P)  =$2500

Interest Rate(R) = 1.8%

(a) So we need to find the interest will the customer earn in 30 years.

the time (T)=30 years

Simple Interest; I=PRT/100

I=2500*1.8*30/100

I=1350

thus the interest will the customer earn in 30 years is $1350.

(b) Now we need  to find the account balance be after 30 years.

The account balance = Principal Amount+Interest Amount

The account balance = 2500+1350

The account balance = $3850

(c) Now we have to find the customer will earn $ in interest.

The customer earn $1350 interest.

Answer:

VP = 21

ZP = 7

Step-by-step explanation:

✔️Given that z is the centroid, thus, based on the centroid theorem:

[tex] VZ = \frac{2}{3}(VP) [/tex]

VZ = 14

Plug in the value of VZ into the equation

[tex] 14 = \frac{2}{3}(VP) [/tex]

Multiply both sides by 3

[tex] 14 \times 3 = \frac{2}{3}(VP) \times 3 [/tex]

[tex] 42 = 2(VP) [/tex]

Divide both sides by 2

42/2 = VP

21 = VP

VP = 21

✔️ZP = VP - VZ

ZP = 21 - 14

ZP = 7

Answer:

8%

Step-by-step explanation:

The computation of the coupon rate is as follows

But before that we have to determine the PMT which is shown below

Given that

PV = $134,996

FV = $100,000

NPER = 11 × 2 = 22

RATE = 4.03% ÷ 2 = 2.015%

The formula is shown below

= PMT(RATE;NPER;-PV;FV;TYPE)

The present value comes in negative

After applying the above formula, the PMT is $4,000

Now the coupon rate is

= Coupon payment ÷ Par value  × 2

= $4,000  ÷ 100,000  × 2

= 8%

Answer:

The value of y = 0.6 when x = -1.

Step-by-step explanation:

Given

To determine

Find 'y' when x = -1

As y directly with x, we express it as:

y ∝ x

y = kx

here 'k' is called the constant of variation

substituting y = -3 and x = 5 to determine the 'k'

y = kx

k = y/x = -3/5

As we have to find 'y' when x = -1

y  = kx

so substituting x = -1 and k = -3/5

y = (-3/5) (-1)

y  = 3/5

y = 0.6

Therefore, the value of y = 0.6 when x = -1.

Some of the 50 students should have been assigned to a control group that used the in-person course

Step-by-step explanation:

Some of the 50 students should have been assigned to a control group that used the in-person course is the concerns makes their conclusion inappropriate.

A learning program that is done in a virtual setting and is organized in accordance with a syllabus is known as an online course. Online courses can be informal and focused on learning a specific skill, or formal and leading to a certification or degree.

Because you may arrange the learning materials so that students can deepen their understanding of a particular subject, online courses are the modernized form of traditional courses. The main component of it is a curriculum, or study plan, broken down into modules.

Hence, Some of the 50 students should have been assigned to a control group.

Answer:

I would say f(x)=5x+7 because the y-values are going up by 5 each time, so to find the y-intercept you need to subtract 5 from 12 and you get 7. The third answer is the only one that has 7 as a y-intercept.
