Answer:

4(x + 12)

Step-by-step explanation:

The sum of a number and 12 indicates addition. Then, it says that this sum will be multiplied by 4. So, we can use x to represent this random number.

Answer:

8 apples to begin with.

Step-by-step explanation:

First, we know that 75% is 3/4 of 100%

If 3/4 = 6 apples then we need to divide each side by three to get 1/4.

So 1/4 = 2

Now, we multiply each side by 4 to get 4/4

So 4/4(100%) = 8

8 apples is the answer

Step-by-step explanation:

Total number of homes in given data is 7+33+56+42+12 = 150

Now out of 150 there is 12 homes who have 4 or more phones

Let's set up proportions

150 / 12 = 100,000 / X

x=100000×12 /150

X=8000

Answer:

4, 16, -4, 2, -1

x = 4±√(16-4(2)(-1)/4

Correct expression:

Step-by-step explanation:

Given the expression

2x² - 8x - 7 = -4x - 6

Rewrite in standard form

2x² - 8x + 4x - 7 + 6 = 0

2x² - 4x  - 1 = 0

Get the coefficients

Given the standard form ax^2 + bx + c = 0

ax^2 = 2x^2

a = 2

bx = -4x

b = -4

c = -1

Use the general formula to find the factors

x = -b±√b²-4ac/2a

Substitute the coefficients

x = -(-4)±√(-4)²-4(2)(-1)/2(2)

x = 4±√(16-4(2)(-1)/4

Hence the values are 4, 16, -4, 2, -1

Answer:

The amount is $1346.86 and the interest is $346.86.

Step-by-step explanation:

To start, use the formula A = P(1+[tex]\frac{r}{n}[/tex])ⁿ°ᵇ [In this case b = time in years]

So, P =  $1000, r = 6$, n = 4 and B = 5 years

After plugging it in you get,

                                                  A = 1000(1+[tex]\frac{.06}{4}[/tex])⁴°⁵

                                                  A = 1000 x 1.015^20

                                                  A = 1000 x 1.346855

                                                  A = 1346.86

To find the interest, use the formula A= P + I; Since A = 1346.86 and P = 1000 you get:

                                                  1346.86 = 1000 + I

                                                  I = 1346.86 - 1000

                                                  I = 346.86

Then you're finished! Hope this helped!

Answer:

a = -5

Step-by-step explanation:

When you're solving a question like this, your aim is to get the unknown (in this case 'a') by itself on one side of the equation. You do this by adding/subtracting/multiplying/dividing, whatever is necessary for the question. Note that if you do something to one side of the equation, you must do the same to the other.

6-3a=21

First let's get rid of the 6: subtract 6 from both sides.

6-6-3a=21-6

-3a=15

Now let's get rid of the -3: divide both sides by -3.

-3a=15

-3a/-3 = 15/-3

a= -5

Complete question :

The Harris Poll conducted a survey in which they asked, "How many tattoos do you currently have on your body?" Of the 1205 males surveyed, 181 responded that they had at least one tattoo. Of the 1097 females surveyed, 143 responded that they had at least one tattoo. Construct a 95% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval.

Answer:

(−0.0085 ; 0.0481)

Step-by-step explanation:

Given that :

n1 = 1205 ; x1 = 181 ; n2 = 1097 ; x2 = 143 ; α = 95%

Zα/2 = 1.96 ( Z table)

Confidence interval : (p1 - p2) ± E

E =Zα/2 * √[(p1q1/n1) + (p2q2/n2)]

p1 = x1 /n1 =181/1205 = 0.1502

q1 = 1 - p1 = 1 -0.1502 = 0.8498

p2 = x2/n2 = 143/1097 = 0.1304

q2 = 1 - p2 = 1 -0.1304 = 0.8696

E = 1.96 * √(0.0001059 + 0.0001033)

E = 0.0283

p1 - p2 = 0.1502 - 0.1304 = 0.0198

Lower boundary = 0.0198 - 0.0283 = −0.0085

Upper boundary = 0.0198 + 0.0283 = 0.0481

(−0.0085 ; 0.0481)
