Answer:

$386

Step-by-step explanation:

If Ann has to pay $2316 twice a year

(every 6 months), then, we calculate

$2316/6 = $386 every month.

Hence, Ann's budget for health

insurance each month is $386.

Hello!

[tex]\large\boxed{x = -2}[/tex]

3(x + 4) = 6

Distribute the terms inside of the parenthesis with the coefficient outside:

3(x) + 3(4) = 6

Simplify:

3x + 12 = 6

Subtract 12 from both sides:

3x + 12 - 12 = 6 - 12

3x = -6

Divide both sides by 3:

3x/3 = -6/3

x = -2

Answer:

0.14secs

Step-by-step explanation:

Given the equation that models the height expressed as;

h(t)=-4.9t^2-v_0 t+h_0

Given v0 = 12m/s

h0 = 1.8m

The equation becomes

h(t)=-4.9t^2-12t+1.8

The height of the ball on the ground level is zero

Substituting into the equation

0 = -4.9t^2-12t+1.8

Multiply through by -10

49t²+120t-18 = 0

Factorize and get t:

t = -120±√120²-4(49)(-18)/2(49)

t = -120±√14400+ 3528/98

t = -120±√17928/98

t = -120±133.89/98

t = 13.89/98

t = 0.14secs

Hence it takes 0.14secs until it reaches the ground

Answer:

Step-by-step explanation:

if you mean x^2+x^2+x^2=3x^2

if x=3, we have 3*3^2=3*9=27

4x^2=4*3^2=4*9=36

Median = 37

Due to the number sequence being an odd number (11 numbers) the median is equal to 37, as there is five numbers that lead up to it.

Answer:

Option C. 25%

Step-by-step explanation:

Gain:-

Selling price - Cost price

= $250 - $200

= $50

Gain percent:-

(Gain/Cost price × 100)%

= (50/200 × 100)%

= 25%

Answer:

D. y <-x - 3

Step-by-step explanation:

-3x + 2y > 5y + 9

Subtract 2y from 5y on the other side

5y - 2y = 3y

-3x > 3y + 9

Add 3x and put it the other side

0 > 3x + 3y + 9

Subtract 3y and put it on the other side

0 - 3y = -3y

-3y > 3x + 9

Divide by -3 on both sides

-3y/-3 > 3x + 9/-3

-3y/-3 = y

3x + 9/-3 = -x - 3

y > -x - 3

MOST IMPORTANT STEP OF ALL: Switch the inequality sign around because you divided with a negative number which is -3. That's a rule in inequality.

y < -x - 3

So your final answer is y < -x - 3

Answer:

Mapping A

Step-by-step explanation:

To clarify this, the first box in each mapping has to go to only one number to resemble a function.  Function A works because each number is going to another number once while Function B doesn't work because of the number 2 going into two numbers.

Given:

[tex]x^2+2x-7=(x+a)^2+b[/tex]

To find:

The values of a and b.

Solution:

We have,

[tex]x^2+2x-7=(x+a)^2+b[/tex]

It can be written as

[tex](x^2+2x)-7=(x+a)^2+b[/tex]

Add and subtract square of half of coefficient of x in the parenthesis.

[tex](x^2+2x+(\dfrac{2}{2})^2-(\dfrac{2}{2})^2)-7=(x+a)^2+b[/tex]

[tex](x^2+2x+1^2)-1-7=(x+a)^2+b[/tex]

[tex](x+1)^2-8=(x+a)^2+b[/tex]     [tex][\because (x+y)^2=x^2+2xy+y^2][/tex]

[tex](x+1)^2+(-8)=(x+a)^2+b[/tex]

On comparing both sides, we get

[tex]a=1[/tex]

[tex]b=-8[/tex]

Therefore, the value of a is 1 and the value of b is -8.

Answer:

The answer is D. An observational study

Step-by-step explanation:

The researchers are observing how different diets in the cattle affects their body composition. They are not counting a population or anything so it is not a census. It is not a sample survey because they aren't asking cows and it is not an experiment because they are not changing or testing anything. They are just viewing meaning it is an observational study.

Answer:

  a)  x = 7

  b)  m∠1 = 45°

  c)  m∠2 = 135°

Step-by-step explanation:

a) Same-side interior angles are supplementary, so we have ...

  ∠1 +∠2 = 180

  (7x -4) +(20x -5) = 180

  27x = 189

  x = 7

__

b) The measures of the angles can be found by substituting the value of x into the express for the angle measure.

  m∠1 = 7x -4 = 7(7) -4 = 45

  m∠1 = 45°

__

c) Angle 2 is the supplement of angle 1, so ...

  m∠2 = 180° -45°

  m∠2 = 135°

__

d) We used the relationship of angles at a transversal and the properties of equality.

Answer:

The solution is (2, 1).

All other ordered pairs do not work.

Step-by-step explanation:

-2x + 5y = 1

5x - 3y = 7

-10x + 25y = 5

10x - 6y = 14

19y = 19

y = 1

5x - 3(1) = 7

5x = 10

x = 2

(2, 1)

The solution is (2, 1).

All other ordered pairs do not work.

The relative frequency for males in the age group 60-69 is 1/2. So, option A is the correct one.

Given that,

Total number of residents in the retirement home who are in the age group 60-69 = 10 + 10 = 20

Number of males who are in the age group 60-69 = 10

The formula to find the relative frequency is,

Relative frequency = Number of counts in the subgroup / Total counts

Substituting,

Relative frequency = 10/20 = 1/2
