What is the value of the expression when a = 6, b = 4,and c = 8? 2a/3b-c A.1 B. 3 C.8 D.12

Need help with this problem

Arisa [49]

Answer:

1/4

Step-by-step explanation:

take the negative reciprocal when finding the slope of a perpendicular line.

So, -4 can be written as -4/1

flip it to make -1/4

and remove the negative to make 1/4

Help please!!!!!...........................

Answer:

See solution :)

Step-by-step explanation:

Let us first analyse our information given. The question tells us that each person, (i.e. Jamie and Stella) should pay $600 upfront. Thus, our first constraint (lets call it $T$ ) is that any total amount of money must be equal or more than $600, which in maths notation reads:

$T\geq 600$

where $\geq$ means More or Equal to.

We also know that Jamie washes care for $25 dollars and if represented in math notation, we can say that for every car (denoted by) $x$ , Jamie makes $25, thus for Jamie we have:

J: $25x$

Similarly we know that Stella makes pecan pies and for each pie she sells she makes $15, so we can say that for every pecan pie (denoted by) $y$ , Stella makes $15, thus for Stella we have:

S: $15y$

However, we also know that Stella does not have enough supplies for more than 40 pies, which puts a constraint on the amount of money she can make by selling pecan pies. Therefore we can now say that

$15y$ is true, for $y\leq 40$

where $y\leq 40$ is the constraint on Stellas possible profits and $\leq$ means Less or Equal to.

Now lets start answering the questions:

Part 1: Write a constraint (an inequality) to represent how much money Jamie needs for his trip.

Answer: $25x$

*provided that $25x\geq 600$ (in order to make the neccesary profit)

Part 2: Write a constraint (an inequality) to represent how much money Stella needs for her trip.

Answer: $15y\geq600$ and $y\leq40$

Part 3: Write a constraint (an inequality) to represent the relationship between Jamie's earnings and Stella's earnings.

Answer: Since Stella can not make more than 40 pies, the solution intersection between Jamie and Stella is $y\geq 40$ (Jamie) ∩ $y\leq40$ (Stella), thus y=40.

Part 4: Can Stella afford to sign up for the trip with the money she earns? Explain your answer and show any work that might support your answer.

Answer: We know that Stella's pie making is denoted by $15y$ , and the total amount needed for the trip upfront is denoted by $T\geq 600$ therefore to find if Stella can afford to sign up, we need to find the amount of pies Stella needs to produce, in order to make a profit of at least $600. Thus we write:

$15y\geq 600\\y\geq \frac{600}{15}\\ y\geq 40$

Since the number of pies Stella needs to make, to gain a profit of $600 is 40 pies, and we know that Stella can make a maximum of 40 pies with the supplies she already has, we can conclude that Stella can make the necessary money to make her trip to Washington!

Based on historical data, your team knows what proportion of the company's number of orders come from Indiana residents. However

marusya05 [52]

This question is incomplete, the complete question is;

Based on historical data, your team knows what proportion of the company's number of orders come from Indiana residents. However, your team would like to expand its orders beyond the state of Indiana. By the end of this year, you think you would like your total proportion of orders from Indiana to be between 0.66 and 0.73. If you took a simple random sample of 99 current orders, what is the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73

Note: You should carefully round any intermediate calculations to 4 decimal places to match wamap's approach and calculations. After you round to 4 places, use THAT rounded value in later steps. You may need an appropriate population proportion (which you actually found in a previous problem).

Some data:

Total population: 2327

Indiana residents: 1845

Other: 482

Frequency table results for Total Sales:

Count = 2327

Total Sales Frequency

0 to 200 1960

200 to 400 303

400 to 600 53

600 to 800 9

800 to 1000 2

Answer:

The probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73 is 0.0612

Step-by-step explanation:

Given the data in the question;

p" = Indiana residents / Total population

p" = 1845 / 2327

p" = 0.7929

Now, the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73 will be;

P( 0.66 < p < 0.73 ) = P{ [x1 - p" / √( p"(1-p")/n )] < p < [x2 - p" / √( p"(1-p")/n )] }

we substitute

= P{ [0.66 - 0.7929 / √( 0.7929(1-0.7929)/99 )] < p < [0.73 - 0.7929 / √( 0.7929(1-0.7929)/99 )] }

= P{ [-0.1329 / 0.0407] < p < [-0.0629 / 0.0407] }

= P{ -3.2654 < z < -1.5455 }

= ⊕( -1.5455) - ⊕(-3.2654)

from the standard normal table;

= 0.0618 - 0.0006

P( 0.66 < p < 0.73 ) = 0.0612

Therefore, the probability that the sample proportion of sales to Indiana residents is between 0.66 and 0.73 is 0.0612
