Which of the following graphs represents the equation y=2x−3?

Answer:

sup

Step-by-step explanation:

Answer:

The decision rule is  

   Fail to reject the null hypothesis

The conclusion is  

   There is no sufficient evidence to accept  the manufacturing company claims

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  35

   The sample standard deviation is  [tex]s =  2.12[/tex]

   The level of significance is [tex]\alpha = 0.01[/tex]

The null hypothesis is  [tex]H_o  :  \sigma ^2  = 9.0[/tex]

The alternative hypothesis is  [tex]H_a  :  \sigma ^2  <  9.0[/tex]

Gnerally the test statistics is mathematically represented as

    [tex]X^2 _{stat} =  \frac{(n -1) * s^2 }{\sigma^2 }[/tex]

    [tex]X^2 _{stat} =  \frac{(35  -1) * 2.12^2 }{9 }[/tex]

=> [tex]X^2 _{stat} =  16.98[/tex]

Generally the degree of freedom is mathematically represented as

   [tex]df =  n - 1[/tex]

=>    [tex]df =  35 - 1[/tex]

=>    [tex]df =  34[/tex]

From the chi - distribution table the  critical value of [tex]\alpha[/tex] at a degree of freedom of  [tex]df =  34[/tex] is  

     [tex]X^2_{\alpha, 34 } =56.060[/tex]

From the value obtained we see that the test statistics does not lie within the region of rejection (1.e 56.060 , [tex]\infty [/tex]   )

Then

The decision rule is  

   Fail to reject the null hypothesis

The conclusion is  

   There is no sufficient evidence to accept  the manufacturing company claims

Answer: Cost of  a giant cookies = $1.39

Cost of a cake= $6.95

Cost of a pie= $4.95

Step-by-step explanation:

Let price of a giant cookie = x

Then,

price of a cake = 5x

Price of a pie = 5x-2

Cost of  30 cakes, 40 pies, and 200 giant cookies = 30 (5x)+40(5x-2)+200x

= 150x+200x-80+200x   [By distributive property a(b+c)=ab+ac]

= 550x-80

Given cost = $684.50

[tex]\Rightarrow\ 550x-80=684.50\\\\\Rightarrow\ 550x= 684.50+80[/tex]

[tex]\Rightarrow\ 550x=764.50\\\\\Rightarrow\ x=\dfrac{764.50}{550}\\\\\Rightarrow\ x=1.39[/tex]

Cost of  a giant cookies = $1.39

Cost of a cake = 5 x $1.39  = $6.95

Cost of a pie = $6.95 -  $2 = $4.95

Answer:

Step-by-step explanation:

To identify the y-intercept represented by the given equation, we need to get the equation into slope-intercept from:

[tex]y=mx+b[/tex]

[tex]m=slope[/tex]

[tex]b=y-intercept[/tex]

Start with:

[tex]3x+2y=6[/tex]

Subtract [tex]3x[/tex] from both sides of the equation:

[tex]2y=-3x+6[/tex]

Divide both sides of the equation by the coefficient of [tex]y[/tex], which is [tex]2[/tex]:

[tex]y=-1.5x+3[/tex]

Identify the y-intercept:

Answer:

awts gege masakit walangya 123456880

Step-by-step explanation:

The answer should be A.

We can start with the fact that x = cos t, y = sin t traces the unit circle counterclockwise once every 2π radians, starting at (1, 0).

By starting at t = π instead of t = 0, we move the starting point to (-1, 0) without changing the direction.

All 5 options have the correct starting point (except D) and number of rotations, but only option A is counterclockwise.

Answer:

$4.90

Step-by-step explanation:

17.15 / 7= 2.45

2.45*2=4.9

the cost of another two pains of glass is $4.90

Answer:

$14.25

Step-by-step explanation:

First write 25% as a decimal by dividing by 100.

[tex]\frac{25}{100}[/tex] = .25

Now multiply the cost of the purse by the discount.

$19 x .25 = $4.75

That is the discount, now subtract the discount from the original price of the purse.

$19 - $4.75 = $14.25

Answer:

1(8/8) - 5/8 = 3/8

Answer:

All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

10−4v=−2−4(−3+v)

Step 1: Simplify both sides of the equation.

10−4v=−2−4(−3+v)

10+−4v=−2+(−4)(−3)+(−4)(v)(Distribute)

10+−4v=−2+12+−4v

−4v+10=(−4v)+(−2+12)(Combine Like Terms)

−4v+10=−4v+10

−4v+10=−4v+10

Step 2: Add 4v to both sides.

−4v+10+4v=−4v+10+4v

10=10

Step 3: Subtract 10 from both sides.

10−10=10−10

0=0

Answer:

The after-tax rate for the Corporate Bond when the tax rate is 10% is 9.35%

Step-by-step explanation:

The investor is better of at any rate above 30%, i.e 31% of tax rate would give the investor 7.1691% return ( 10.39  −  ( 10.39  ⋅  31 % ) )

Thus the return from the tax exempt municipal bond would be higher than the return from the taxable corporate bond.

The after-tax rate for the Corporate Bond when the tax rate is 10% is 9.35%( 10.39  −  ( 10.39  ⋅  10 % ) )

Answer:

a) P(A) = 0,4607     or   P(A) = 46,07 %

b) P(B) = 0,7120   or 71,2 %

c) P(C) = 0,2055  or P(C) = 20,55 %

Step-by-step explanation:

We will use two concepts in solving this problem.

1.- The probability of an event (A) is for definition:

P(A) = Number of favorable events/ Total number of events FE/TE

2.- If A and B are complementary events ( the sum of them is equal to 1) then:

P(A) = 1 - P(B)

a) The total number of events is:

C ( 24,4) = 24! / 4! ( 24 - 4 )!    ⇒  C ( 24,4) = 24! / 4! * 20!

C ( 24,4) = 24*23*22*21*20! / 4! * 20!  

C ( 24,4) = 24*23*22*21/4*3*2

C ( 24,4) = 24*23*22*21/4*3*2    ⇒  C ( 24,4) =  10626

TE = 10626

Splitting the group of tanks in two 6 with h-v  and 24-6 (18) without h-v

we get that total number of favorable events is the product of:

FE = 6* C ( 18, 3)  = 6 * 18! / 3!*15!  =  18*17*16*15!/15!

FE =  4896

Then P(A) ( 1 tank in the sample contains h-v material is:

P(A) = 4896/10626

P(A) = 0,4607     or   P(A) = 46,07 %

b) P(B) will be the probability of at least 1 tank contains h-v

P(B) = 1 - P ( no one tank with h-v)

Again Total number of events is 10626

The total number of favorable events for the ocurrence of P is C (18,4)

FE = C (18,4) = 18! / 14!*4! = 18*17*16*15*14!/14!*4!

FE = 18*17*16*15/4*3*2  = 3060

Then P = 3060/10626

P = 0,2879

And the probability we are looking for is

P(B) = 1 - 0,2879

P(B) = 0,7120   or 71,2 %

c) We call P(C) the probability of finding exactly 1 tank with h-v and t-i

having 4 with t-i tanks is:

reasoning the same way but now having 4 with t-i (impurities) number of favorable events is:

FE = 6*4* C(14,2) = 24 * 14!/12!*2!

FE = 24* 14*13*12! / 12!*2

FE = 24*14*13/2    ⇒  FE = 2184

And again as the TE = 10626

P(C) = 2184/ 10626

P(C) = 0,2055  or P(C) = 20,55 %

Answer:

4.66 x 10^9

Step-by-step explanation:

The performance of the computer in one minute is 2.70x10¹⁰ per minute after performing unit conversion.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

It is given that:

A computer can perform 4.66 x 10⁸ calculations per second,

As we know,

1 minute = 60 seconds

1 second = 1/60 minutes

The performance of the computer in one minute = 4.66 x 10⁸(1/(1/60))

The performance of the computer in one minute = 4.66x60x 10⁸

The performance of the computer in one minute = 279.6x10⁸

= 2.70x10¹⁰ per minute

Thus, the performance of the computer in one minute is 2.70x10¹⁰ per minute after performing unit conversion.

His parents cover 9100+ the scholarship for 3300=12400

Answer:

Step-by-step explanation:

You are to make 5 assemblies.

Each assembly requires the use of 1 Type A bolt.

To make the 5 assemblies, you need 5 Type A bolts.

The container of bolts has a total of 60 bolts.

The focus - Type A bolts - is 20 out of this 60.

The probability of obtaining a Type A bolt at all, is 20/60, which is = 1/3

(A) What is the probability of taking the exact number of Type A bolts you need for your 5 assemblies, if you randomly take 10 bolts from the container?

- The exact number of Type A bolts you need for the 5 assemblies is 5

1/3 × 5/10 =  5/30 =  1/6 =  0.167

(B) What is the probability of taking/having less than 5 Type A bolts out of the randomly selected 10 bolts? The solution is to sum up the following:

1/3 × 4/10 = 0.133

1/3 × 3/10 = 0.1

1/3 × 2/10 = 0.067

1/3 × 1/10 = 0.033

1/3 × 0/10 = 0

TOTAL = 0.333
