1. A fast food outlet claims that the mean waiting time in line is less than 3.8 minutes. A random sample of 60 customers has a mean of 3.7 minutes with a population standard deviation of 0.6 minute. If α = 0.01, test the fast food outlet's claim.

Answers

Answer 1

Answer:

There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes

Step-by-step explanation:

H0 : μ = 3.8

H1 : μ < 3.8

Test statistic :

(x - μ) ÷ s/sqrt(n)

(3.7 - 3.8) ÷ 0.6/sqrt(60)

Test statistic = - 1.29

The Pvalue from test statistic :

P(z < -1.29) = 0.0985

Reject Null if

Pvalue < α

0.0986 > 0.01 ; Hence, we fail to reject the null ;

There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes

Find measure FGH circles unit

Answers

Answer:

[tex] \huge \orange{m\widehat {FGH} =238\degree} [/tex]

Step-by-step explanation:

Quadrilateral AFGH is inscribed in a circle. So, it is a cyclic quadrilateral. Opposite angles of a cyclic quadrilateral are supplementary.

[tex] \therefore m\angle FGH + m\angle FAH = 180\degree [/tex]

[tex] \therefore (21x-2)\degree + (38x +5)\degree = 180\degree [/tex]

[tex] \therefore (21x-2+38x +5)\degree = 180\degree [/tex]

[tex] \therefore 59x+3= 180[/tex]

[tex] \therefore 59x= 180-3 [/tex]

[tex] \therefore 59x= 177 [/tex]

[tex] \therefore x= \frac{177}{59}[/tex]

[tex] \therefore x=3[/tex]

Now, by inscribed angle theorem:

[tex] m\angle FAH = \frac{1}{2} m\widehat {FGH} [/tex]

[tex] (38x +5)\degree = \frac{1}{2} m\widehat {FGH} [/tex]

[tex] 2(38\times 3+5)\degree = m\widehat {FGH} [/tex]

[tex] 2(119)\degree = m\widehat {FGH} [/tex]

[tex] 238\degree = m\widehat {FGH} [/tex]

[tex] \huge \purple {\boxed {m\widehat {FGH} =238\degree}} [/tex]

Barrett is comparing the membership fees for two museums.The art museum charges a one-time fee of $8.25 plus $2.25 per month. The science museum charges a one-time fee of $10.75 plus $3.50 per month. How much does Barrett save after m months by joining the art museum instead of the science museum?

Answers

Answer:

$2.50+$1.25 times M

Step-by-step explanation:

$10.75-$8.25=$2.50

$3.50-$2.25=$1.25

$2.50+$1.25=$3.75

As only one-time fee, we cancel out it, then only add on the per-month fee, which is $1.25 every month.

Answers

Answer:

2248+2224.91= 4472.91

Step-by-step explanation:

A = $2,248.00

I = A - P = $248.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3.1%/100 = 0.031 per year.

Solving our equation:

A = 2000(1 + (0.031 × 4)) = 2248

A = $2,248.00

The total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 3.1% per year for 4 years is $2,248.00.

A = $2,224.91

A = P + I where

P (principal) = $2,000.00

I (interest) = $224.91

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.7/100

r = 0.027 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 2,000.00(1 + 0.027/1)(1)(4)

A = 2,000.00(1 + 0.027)(4)

A = $2,224.91

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $2,000.00 at a rate of 2.7% per year compounded 1 times per year over 4 years is $2,224.91.

I will appreciate thank you so much!

Answers

Answer:

x = -1

y = 1

Step-by-step explanation:

x + 2y = 1     (Multiply this by -2)

2x + 5y = 3

-2x - 4y = -2

2x + 5y = 3

y = 1

x + 2y = 1

x + 2(1) = 1

x + 2 = 1

x = 1 - 2

x = -1

Answer:

x = -1

y = 1

Step By Step Explanation:

x + 2y = 1

2x + 5y = 3

let x become the subject. use one of the equation.

x = 1 - 2y

substitute into another equation

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

expend the bracket

2 - 4y + 5y = 3

collect like terms

- 4y + 5y = 3 - 2

y = 1

substitute into one of the equation to find x

x + 2y = 1

x + 2 (1) = 1

x + 2 = 1

collect like terms

x = 1 - 2

x = - 1

Rate of change per year____
Initial value____

Help me please :))) <3 ~

Answers

Answer:

7

8

Step-by-step explanation:

The rate of change per year is the number of books she gets each year.

The problem states "She will buy 7 new puzzle of books each year."

The rate of change per year is 7.

The initial value is the beginning value.

She gets 7 book each year. In 5 years, she gets 5 * 7 = 35 books.

She will have 35 additional books in 5 years. She will have a total of 43 books in 5 years.

43 - 35 = 8

She started with 8 books.

The initial value is 8.

What is the relationship between factoring and distribution?

Answers

Answer:

UwU

Step-by-step explanation:

Use the distributive property to factor a monomial out of a polynomial. Factors are numbers that multiply together to produce another number. For example, 2 and 10 are factors of 20, as are 4 and 5 and 1 and 20. Factoring is the process of breaking a number down into its multiplicative factors.

Answer: Factoring is the opposite of using the distributive property to multiply. If you had: 7(3x + 8), you would distribute the 7 and multiply it both both terms. Factoring reverses that process.

To stich a shirt, 2m 15cm cloth is needed. Out of 40m cloth,how many shirts can be stiched and how many will remain?

Answers

Answer:

18 shirts can be made and 130 cm of clothes will remain unstitched.

Step-by-step explanation:

Given that,

Total length of the cloth = 40 m = 4000 cm

Amount needed to stitch a shirt = 2m 15cm = 215 cm

Now dividing 4000 by 215 to get the number of shirts that can be stitched and no. of shirts remain. After dividing, we get quotient as 18 and remainder as 130.

So, 18 shirts can be made and 130 cm of clothes will remain unstitched.
