Answer:

1 and 2/3 hours (One hour and 40 minutes.)

Step-by-step explanation:

Karen has 3 and 1/3 hours.

She spends 1 and 2/3 hours at the store.

3 and 1/3 - 1 and 2/3 = 1 and 2/3 or 5/3 is the time she had left after being at the grocery store.

Because the rest of the time was spent at the library, that is your answer.

Answer:

where are the awnsers??

The value of the initial deposit is $2,960, so a1=2960. A total of 26 six-month deposits are made in the 13 years, so n=26. To find r, divide the annual interest rate by 2 to find the biannual interest rate and add 1 to represent the new biannual deposit.

r=1+0.072=1.035

Substitute a1=2960, n=26, and r=1.035 into the formula for the sum of the first n terms of a geometric series and simplify to find the value of the annuity.

S26=2960(1−1.03526)1−1.035≈122286.78

Therefore, the account has $122,286.78 after the last deposit is made.

The solution to the equation is x = 2 , x = 1/2

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 equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

( 2x - 4 ) ( 2x - 1 ) = 0

So , the two values of x are

when ( 2x - 4 ) = 0

Adding 4 on both sides , we get

2x = 4

Divide by 2 on both sides , we get

x = 2

And , when ( 2x - 1 ) = 0

Adding 1 on both sides , we get

2x = 1

Divide by 2 on both sides , we get

x = 1/2

Hence , the solution is x = 2 , 1/2

Answer: Cosec 2 A + Cot 4 A = Cosec 4 A - Cot 2 A

Step-by-step explanation:

Taking LHS  :

⇒Cosec 2 A + Cot 4 A

⇒Cosec 2 A + ( Cot 2 A )2

⇒Cosec 2 A + ( Cosec 2 A - 1 )2  (  we know : 1 + Cot 2 θ =  Cosec 2 θ )

⇒Cosec 2 A +  Cosec 4 A  + 1  - 2 Cosec 2 A

⇒ Cosec 4 A  + 1  - Cosec 2 A

The correct order which shows the standard deviations of the data sets A,B and C in order from greatest to least is C, B, A.

Suppose that

[tex]x_i; \: \: i = 1,2, ... ,n[/tex] are n data values for the given data set.

Then we have: Variance as,

[tex]\sigma^2 = \dfrac{\sum_{\forall x_i} (x_i - \overline{x})^2}{n}[/tex]

As standard deviation is the positive root of variance, thus,

[tex]\sigma = \sqrt {\dfrac{\sum_{\forall x_i} (x_i - \overline{x})^2}{n}}[/tex]

If its sample, we divide by n-1 instead of n

Use data sets A, B, and C to answer the question that follows.

The mean of the set A is,

[tex]\overline{x}_A=\dfrac{25+24+ 25+ 22+ 21+23+ 1}{7}=20.143[/tex]

Similarly, the mean of set B and C is,

[tex]\overline{x}_B=\dfrac{20+ 23+ 25+ 21+ 24+ 22+ 60}{7}=27.857\\\overline{x}_C=\dfrac{20+21+ 20+ 22+ 20+ 24+ 99}{7}=32.286[/tex]

The standard deviation of the set A is,

[tex]\sigma_A = \sqrt {\dfrac{(25-20.143)^2+(24-20.143)^2......+(1-20.143)^2}{7}}\\\sigma_A = 7.936[/tex]

Similarly, the standard deviation of set B and C is,

[tex]\sigma_B = \sqrt {\dfrac{(20-27.857)^2+(23-27.857)^2......+(60-27.857)^2}{7}}= 13.217\\\sigma_C = \sqrt {\dfrac{(20-32.286)^2+(21-32.286)^2......+(99-32.286)^2}{7}}= 27.27[/tex]

The value of standard deviation of set C is the highest while set A is lowest.

Thus, the correct order which shows the standard deviations of the data sets A,B and C in order from greatest to least is C, B, A.

Step-by-step explanation:

Answer:

Step-by-step explanation:

GIVEN:

In order to solve this, you need to isolate the term x on one side of the equation.

First, combine like terms.

[tex]\Longrightarrow: \sf{8x+16x+21=25x+19}[/tex]

Solve.

8x+16x=24x

[tex]\Longrightarrow: \sf{24x+21=25x+19}[/tex]

You have to subtract by 21 from both sides.

[tex]\Longrightarrow: \sf{24x+21-21=25x+19-21}[/tex]

Solve.

[tex]\Longrightarrow: \sf{24x=25x-2}[/tex]

Subtract by 25x from both sides.

[tex]\Longrightarrow: \sf{24x-25x=25x-2-25x}[/tex]

Solve.

-x=-2

Then, you divide by -1 from both sides.

[tex]\Longrightarrow: \sf{\dfrac{-x}{-1}=\dfrac{-2}{-1}}[/tex]

Solve.

Divide the numbers from left to right.

[tex]\sf{\dfrac{-2}{-1}=2 }[/tex]

SOLUTIONS:

[tex]\Longrightarrow: \boxed{\sf{x=2}}[/tex]

I hope this helps. Let me know if you have any questions.

Answer:

[tex]x = 2[/tex]

Given equation:

Combine like terms on the L.H.S and simplify the expression as needed.

Now, rewrite 25x in such a way such that 24x can be repeated on both sides. Clearly, we can rewrite 25x as 24x + x. Then,

Since 24x is being repeated on both sides, we can cancel it.

Finally, subtract 19 on both sides to isolate x.

Therefore, the value of x is 2.

You can find and write the equations in Slope-Intercept form due to the slope and y-intercept.

Step-by-step explanation:

The Slope-Intercept Form Formula: y=mx+b

The m represents the slope while the b represents the y-intercept

You can also use y2 - y1 / x2 - x1 to find the slope which is the m in your formula.

Lastly, to find a y-intercept, you can plug in your coordinate for the x and y to do two-step linear equations.

Answer:

C

Step-by-step explanation:

Remark

The zeros are found either by using the quadratic equation or by factoring and equating the factors to 0. I think factoring is the best and simplest way.

Solution

x^2 - 5x + 6 factors into

(x - 3)(x - 2)

-3 and - 2 must multiply to 6 (they do) -3 * -2 = 6

-3 and -2 must also add to - 5. They do. -3 - 2 = - 5

So the factors are correct.

x - 3  = 0

x - 3 + 3 = 0 + 3

x = 3

x-2 = 0

x -2 + 2 = 0 + 2

x = 2

Answer

x = 2 and x = 3

The answer is C

We will see that the equation has only one solution, so the correct option is B.

For an equation of the form:

p(x) = C

Where p(x) is an expression that depends on x, and C is a constant.

The solutions are all the values of x that make the equality true.

For our case, we have:

x = -5

Notice that there is only one value of x that makes the equality true, if we replace x by -5 we get:

-5 = -5

So that is the only solution for the equation, then we conclude that the equation has only one solution, and the correct option is B.

See below ~

Step-by-step explanation:

Answer:

Hello! The solution to this linear equation is 0 = 0. To find this solution:

Distribute -

8 - 2(4v+6) = -4 - 8v

8 - 8v - 12 = 14 - 8v

Subtract the numbers -

8 - 8v - 12 = -4 - 8v

-4 - 8v =  -4 - 8v

Rearrange terms -

-4 - 8v = -4 - 8v

-8v - 4 = -4 - 8v

Rearrange terms -

-8v - 4 = -4 - 8v

-8v - 4 = -8v - 4

Add 4 to both sides -

-84v - 4 = -8v - 4

-8v - 4 + 4 = -8v - 4 + 4

Simplify -

-8v - 4 + 4 = -8v - 4 + 4

-8v = -8v - 4 + 4

-8v = -8v

Add 8v to both sides -

-8v = -8v

-8v + 8v = -8v + 8v

Combine like terms and simplify -

-8v + 8v = -8v + 8v

0 = -8v + 8v

0 = 0

The solution is 0 = 0. This is an identity: it is true for all values.

Hope this helps! Have a great day.

Perimeter:-

Answer:

104 inches

Step-by-step explanation:

A kite has two pairs of consecutive, congruent sides.

Therefore, BC = AB  and  AD = DC

We can use this to determine the values of x and y, and then the perimeter of the kite.

If BC = AB

⇒ 5x = 3x + 12

Subtract 3x from both sides:

⇒ 2x = 12

Divide both sides by 2

⇒ x = 6

If AD = DC

⇒ 11y - 22 = 7y - 6

Subtract 7y from both sides:

⇒ 4y - 22 = -6

Add 22 to both sides:

⇒ 4y = 16

Divide both sides by 4:

⇒ y = 4

As BC = AB  and  AD = DC

⇒ perimeter = 2 (BC + AD)

                     = 2 (5x + 11y - 22)

Substituting found values of x and y:

⇒ perimeter = 2 (5(6) + 11(4) - 22)

                     = 2 (30 + 44 - 22)

                     = 2 (52)

                     = 104 inches
