Answer:

x=-1.625  Decimal form  

x= -13/8    Fraction form

Step-by-step explanation:

3(-2x-1)=2(x+5)

Use distributive property to solve-

-6x-3=2x+10

Now add like terms

-6x-3=2x+10

    +3       +3

   -6x=2x+13  (get the x by itself)

  -2x    -2x

-8x=13     Divide

x= -1.625   Decimal form

x=-13/8   Fraction form

Answer:

[tex]20[/tex]

Step-by-step explanation:

The area of the front side of the toy model is [tex]1\ \text{ft}^2[/tex]

The area of the real building's front side is [tex]400\ \text{ft}^2[/tex]

So

[tex]1\ \text{ft}^2[/tex] of the toy model is equivalent to [tex]400\ \text{ft}^2[/tex] of the real building.

Area scale factor is given by [tex]k^2[/tex], where [tex]k[/tex] is the scale factor of the sides.

So,

[tex]\dfrac{400}{1}=k^2\\\Rightarrow k=\sqrt{400}\\\Rightarrow k=20[/tex]

Hence, the scale factor is [tex]20[/tex].

The scale factor should be 20.

The area of the front side of the toy building is 1 square foot. The real building's front side has an area of 400 square feet.

Since 1 square foot should be equal to 400 square feet

So,

[tex]400\div 1 = k^2[/tex]

[tex]K = \sqrt{400}[/tex]

k = 20

Answer:

Step-by-step explanation:

Given that:

population mean = 150

Sample size  = 10

Sample mean = 136

Standard deviation = 28

Significance level = 0.05

The null hypothesis:

[tex]H_o : \mu \ge 150[/tex]

The alternative hypothesis

[tex]H_a : \mu < 150[/tex]

This is a left-tailed test.

The t-test statistics can be computed as:

[tex]t = \dfrac{\overline x - \mu}{ \dfrac {s} {\sqrt{n}} }[/tex]

[tex]t = \dfrac{136 - 150}{ \dfrac {28} {\sqrt{150}} }[/tex]

t = -1.58

The P-value = P(t < -1.58)

Using the t tables

P-value = 0.0743

Decision rule: To reject the null hypothesis if the P-value is lesser than the level of significance.

Conclusion: We fail to reject the null hypothesis; since P-value is greater than (∝). Thus, there is sufficient evidence to support Fred's Claim.

No, we can not reject Fred's claim.

Answer:

$416.00

Step-by-step explanation:

Leslie's 10% and her employer's 3% total 13% of her salary:

0.13 · $3200 = $416

The maximum monthly deposit to Leslie’s 401(k) account, including her employer’s matching contribution, is $416.

A matching contribution is a type of contribution that Leslie's employer decides to contribute to Leslie's 401(k) plan, which is an employer-sponsored retirement plan.

Monthly salary = $3,200

Leslie's maximum contribution = 10% of salary

Employer's matching contribution = 3% of salary

Total contributions to the 401(k) plan = 13% of salary

= $416 ($3,200 x 13%)

Thus, the maximum monthly deposit to Leslie’s 401(k) account, including her employer’s matching contribution, is $416.

Answer:

$62.50

Step-by-step explanation:

The amount of private mortgage insurance required in this case per annum is 0.75% of the entire loan which is $100,000.

Annual insurance=0.75%*loan amount

Annual insurance=0.75%*$100,000

Annual insurance=$750

Since the annual cost of mortgage insurance per year is established, monthly cost would be annual cost divided by 12 months is which is number of months in a year that payments are to be made

monthly payment=$750/12

monthly payment=$62.50

Answer:

[tex]\int\limits {e^{2s} cos\frac{s}{4} ds[/tex]    =[tex]\frac{4 e^{2s} }{65 } ({8 cos (\frac{1}{4} ) s + sin \frac{1}{4} s} ))[/tex]

Step-by-step explanation:

Step(i):-

Given that  [tex]f(s) = e^{2s} cos\frac{s}{4}[/tex]

Now integrating

            [tex]\int\limits {f(s)} \, ds = \int\limits {e^{2s} cos\frac{s}{4} ds[/tex]

By using integration formula

   [tex]\int\limits { e^{ax} cos b x dx = \frac{e^{ax} }{a^{2}+b^{2} } ( a cos b x + b sin b x )[/tex]

Step(ii):-

 [tex]\int\limits {e^{2s} cos\frac{s}{4} ds[/tex]    =   [tex]\frac{e^{2s} }{(2)^{2}+(\frac{1}{4}) ^{2} } ( 2 cos (\frac{1}{4} ) s + \frac{1}{4} sin \frac{1}{4} s ))[/tex]  

                    = [tex]\frac{e^{2s} }{(4+\frac{1}{16})} ( 2 cos (\frac{1}{4} ) s + \frac{1}{4} sin \frac{1}{4} s ))[/tex]

                   = [tex]\frac{e^{2s} }{(\frac{65}{16} } ( \frac{8 cos (\frac{1}{4} ) s + sin \frac{1}{4} s}{4} ))[/tex]

                 = [tex]16 X\frac{e^{2s} }{65 } ( \frac{8 cos (\frac{1}{4} ) s + sin \frac{1}{4} s}{4} ))[/tex]

                 =[tex]\frac{4 e^{2s} }{65 } ({8 cos (\frac{1}{4} ) s + sin \frac{1}{4} s} ))[/tex]

Final answer:-

[tex]\int\limits {e^{2s} cos\frac{s}{4} ds[/tex]    =[tex]\frac{4 e^{2s} }{65 } ({8 cos (\frac{1}{4} ) s + sin \frac{1}{4} s} ))[/tex]
