The owners of an eyeglass store claim that they fill customers' orders, on average, in 60 minutes with a standard deviation of 15. 9 minutes. Based on a random sample of 40 orders, a reporter determines a mean order time of 63 minutes. Let µ represent the average number of minutes to fill an order. Z = StartFraction x overbar minus mu Over (StartFraction sigma Over StartRoot n EndRoot EndFraction) EndFraction To the nearest hundredth, the z-statistic is z =.

Answers

Answer 1

By applying z-score formula we got that if a reporter determines a mean order time of 63 minutes then value o Z is 1.19

What is standard deviation?

Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value

Here given that

The owners of an eyeglass store claim that they fill customers' orders, on average, in 60 minutes with a standard deviation of 15. 9 minutes. Based on a random sample of 40 orders, a reporter determines a mean order time of 63 minutes

mean=μ=60

standard deviation=σ=15.9

number of sample=n=40

[tex]\bar{x}=63 \\[/tex]

Now we can calculate z by z-score formula as

[tex]z=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}} \\\\&=\frac{63-60}{\frac{15 \cdot 9}{40}} \\ \\=\frac{3}{2.5140} \\ \\=1.19\end{aligned}[/tex]

Answer:

1090 yd squared

Step-by-step explanation:

First, let's find the area of the base

16 x 17 = 272

Now let's find the triangular face

1/2 x 16 x 15

8 x 15 = 120

Since there are 2, we multiply 120 by 2

240

Now the rectangular face

17 x 17 = 289

Since there are 2, we multiply 289 by 2

289 x 2 = 578

Now we add them all together

578 + 240 + 272 = 1090

1090 yd squared

Alice, Andrew, and six other students are to be divided into two teams of four people. How many ways are there to form the teams so that Alice and Andrew are on opposite teams

Answers

The number of ways there are to form the teams so that Alice and Andrew are on opposite teams is 2 ways.

Combination

Since Alice, Andrew, and six other students are to be divided into two teams of four people, and we require the number of ways to form the teams so that Alice and Andrew are on opposite teams, this is a combination question since order doesn't matter.

Number of ways of combining the first team

For the first team of 4, if Alice takes the first position, then there are 3 positions left to be occupied by the remaining 3 persons.

So, the number of ways of combining this team is n = 1 × ³C₃

= 1 × 1

= 1 way

Number of ways of combining the second team

Also, for the second team of 4, if Andrew takes the first position, then there are 3 positions left to be occupied by the remaining 3 persons.

So, the number of ways of combining this team is N = 1 × ³C₃

= 1 × 1

= 1 way

Number of ways of combining both teams

So, the number of ways teams can be formed so that Alice and Andrew are on opposite teams is N' = n + N

= 1 + 1

= 2 ways

So, the number of ways there are to form the teams so that Alice and Andrew are on opposite teams is 2 ways.

Aaliyah and Phildres are joining a gym that offers two different payment plans. Aaliyah
chooses Plan A, and Phildres chooses Plan B.
Which equation can be used to solve for the number of classes, c, for which the cost
of Plan A equals Plan B?

Answers

Answer:

50c=10c+200

Step-by-step explanation:

Two different payment plans, the equation which can solve for the number of classes that equates to both plans is 200 + 10c = 50c.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

To solve for the number of classes, c, for which the cost of Plan A equals Plan B, you can use the equation: 200 + 10c = 50c.

In this equation, the left-hand side represents the cost of Plan B, and the right-hand side represents the cost of Plan A. The variable, c, represents the number of classes that Aaliyah and Phildres attend.

To solve for c, you can use algebraic techniques to isolate the variable on one side of the equation. For example, you could subtract 10c from both sides of the equation to obtain: 200 = 40c. Then, you could divide both sides of the equation by 40 to obtain: 5 = c.

Therefore, the number of classes, c, for which the cost of Plan A equals Plan B is 5.
