Answer:

The confidence interval = (7.8 , 8.0)

Step-by-step explanation:

Confidence Interval formula =

Mean ± z × Standard deviation/√n

Mean = 7.9

Standard deviation = 0.9

n = number of samples = 164

z = z score of an 80% confidence interval = 1.282

Confidence Interval = 7.9 ± 1.282 × 0.9/√164

= 7.9 ± 0.0900966432

Confidence Interval

= 7.9 - 0.0900966432

= 7.8099033568

Approximately to 1 decimal place = 7.8

7.9 + 0.0900966432

= 7.9900966432

Approximately to 1 decimal place = 8.0

Therefore, the confidence interval = (7.8 , 8.0)

Actually, -13 can be classified as any and all of these.

Answer:-13 would be considered a rational number :)

Step-by-step explanation:

Only positive numbers are considered as whole numbers, so we know that that is not a correct option, and an integer is any number that is not either a decimal or a fraction. Hope this helps :)

Answer:

Option C : P = $1040

Step-by-step explanation:

Using formula for continuous compounding, we have;

FV = Pe^(rt)

Where;

FV is the future value

P is the starting principal

r is the interest rate

t is time period

Now, from the question;

After 9 years, value is 1,866.79

Hence;

Pe^(9r) = 1,866.79 - - - eq1

Also, after 18 years;

Pe^(18r) = $3,350.87

Now, from exponential functions,

e^(4) can be written as (e^(2))²

Thus,in our case, e^(18r) can simply be written as (e^(9r))²

Thus, we can write Pe^(18r) = $3,350.87 as;

P(e^(9r))² = 3,350.87 - - - eq3

Thus, dividing eq 1 by eq 3 gives;

P(e^(9r))²/Pe^(9r) = 3350.87/1866.79

e^(9r) = 1.794990331

So;

In 1.794990331 = 9r

r = 0.585/9

r = 0.065

Putting this for r in equation 1 gives;

Pe^(9 × 0.065) = 1,866.79

1.795P = 1,866.79

P = 1866.79/1.795

P = $1040

Making the value of 'a' smaller, but still positive, will make the graph be compressed vertically.

Let's say a = 1 is the initial value. If we update it to a = 0.5, then the graph will be half as tall as it used to be, so it's compressed by a factor of 1/0.5 = 2.

The value of b determines the period of the sinusoidal function.

Factor to this equation out, the easiest way is to solve for the two x values that add up to -1 but when multiplied is equal to -6. It should look like this: (x +- ?)(x +- ?).

The factored out form is then (x - 3)(x +2), because -3 + 2 = -1 and when multiplied together gives -6.

x - 3 = 0

x = 3

x + 2 = 0

x = -2

The two solutions are therefore, x = 3 and x = -2.

Answer:

B.  2x² + x² + x = 30

D.  9x + 3x² = 14 + x - 1

Step-by-step explanation:

2x² + x² + x = 30

simplify

3x² + x - 30 = 0

x can be solve using quadratic equations

x = 3    and x = -10/3

so the answer is B

9x + 3x² = 14 + x - 1

simplify

3x² + 8x - 13 =0

x can be solve using quadratic equations

so the answer is D

Note: options A and C do not qualify for quadratic equation

The solution is Option B , Option D.

The set of quadratic equations are 2x² + x² + x = 30 and 9x + 3x² = 14 + x -1

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

a)

2x² + x² + x = 30   be equation (1)

On simplifying the equation , we get

3x² + x = 30

Subtracting 30 on both sides of the equation , we get

3x² + x - 30 = 0

Now , on factorizing the equation , we get

x = 3 and x = -10/3

b)

9x + 3x² = 14 + x -1   be equation (1)

On simplifying the equation , we get

Subtracting x on both sides of the equation , we get

3x² + 8x = 13

Subtracting 13 on both sides of the equation , we get

3x² + 8x - 13 = 0

Now , on factorizing the equation , we get

x = ( -4/3 ) ± ( √55/3 )

Hence ,

The quadratic equations are 2x² + x² + x = 30 and 9x + 3x² = 14 + x -1

Answer:

1,249 cm or 12.49

Whichever one it asks for

Step-by-step explanation:

First, we need to convert all of the m to cm.

4.04 m = 404 cm

1.6 m = 160 cm

2.87 m = 287 cm

Next, add them all up.

325 + 404 + 73 + 160 + 287 =

If it asks to convert to m again, then the answer would be 12.49 m

Hope this helps!!!

Answer:

1,249 cm (or) 12.49 m

Step-by-step explanation:

1m = 100cm

The amount of gas left with Jess is given by the equation A = 1/6 of the total gas

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount of the gas be represented as A

Now , the equation will be

The amount of gas utilized by Jess on Friday = 1/2 of the initial gas

So , The amount of gas left on Friday = A - ( 1/2 ) A

On simplifying the equation , we get

The amount of gas left on Friday = ( 1/2 )A

Now ,

Amount of gas utilized by Jess on Saturday = ( 1/3 ) of the remaining gas

On simplifying the equation , we get

The remaining gas = ( 1/2 ) A - ( 1/3 ) A

Answer:

1) [tex]50=2(x+5)+2(x)[/tex]

2) [tex]x=10[/tex]

3) [tex]15\text{ units}[/tex]

Step-by-step explanation:

So we know that the perimeter of the rectangle is 50.

The formula for the perimeter of a rectangle is given by:

[tex]P=2l+2w[/tex]

Where l is the length and w is the width.

The length is (x+5) and the width is (x).

Thus, substitute (x+5) for l and (x) for w. Also substitute 50 for P. Therefore:

[tex]50=2(x+5)+2(x)[/tex]

And that's our equation.

To solve, first distribute:

[tex]50=2x+10+2x[/tex]

Combine like terms:

[tex]50=4x+10[/tex]

Subtract 10 from both sides:

[tex]40=4x[/tex]

Divide everything by 4:

[tex]x=10[/tex]

So, the value of x is 10.

The length is the longer side. Thus, it is (x+5).

We now know that x is 10, substitute:

[tex]x+5\\=(10)+5\\=15[/tex]

So, the length is 15 units.

Answer:

Below

Step-by-step explanation:

The perimeter of a rectangle is the sum of its 4 sides.

Let P be the perimeter

● P = x + (x+5) + x + (x+5)

● P = x+x+x+x+5+5

The perimeter is 50 units

● 50 = 4x +10

So this the equation that would model how to find x.

Let's solve it

● 4x + 10 = 50

Substract 10 from both sides

● 4x + 10 - 10 = 50-10

● 4x = 40

Divide both sides by 4

● 4x/4 = 40/4

● x = 10

■■■■■■■■■■■■■■■■■■■■■■■■■■

Let's find the length.

The length is x+5

Replace x by 10 to find the value of the length.

● 10 + 5 = 15

So the length is 15 units
