A customer buys bouquets of tulips and bouquets of roses for $.. What is the price of a bouquet of roses?
Question:
A customer buys bouquets of tulips and bouquets of roses for $40.25. The bouquet contained 17 tulips and cost $18.25. What is the price of a bouquet of roses?
Answer:
[tex]Rose =\$22.00[/tex]
Step-by-step explanation:
Given
[tex]Total = \$40.25[/tex]
[tex]Tulips = \$18.25[/tex]
Required
The cost of a bouquet of roses
Since the customer bought a bouquet each, the formula to use is:
[tex]Total = Tulip + Rose[/tex]
Make Rose the subject
[tex]Rose =Total - Tulip[/tex]
[tex]Rose =\$40.25 - \$18.25[/tex]
[tex]Rose =\$22.00[/tex]
A bouquet of rose costs $22.00
helpppppppppppppppppp
Answer and Step-by-step explanation:
The independent variable is m, and the dependent variable is h.
This is because you can plug in any value for m, making m NOT have to depend on any other value to become m.
With h, it needs the result of m and its other values to become the result of h. H relies/depends on the values in the equation to become a value.

) At a certain college, students are allowed to choose between online and in-person learning. 70% of the students choose online learning and 30% choose to come to campus for in-person instruction. Assume that the probability that a person studying online will contract the coronavirus is .02 and the probability that a person attending class in-person contracts the virus is .35 . (a) What is the probability that a person attending this college (either online or in-person) will contract the virus
Answer:
Probability = 0.119
Step-by-step explanation:
P (Coronavirus) = P(Person online & corona) or P(Person offline & corona)
(0.70 x 0.02) + (0.30 x 0.35)
0.014 + 0.105

Explain why inequalities of the form x > cor
x
Step-by-step explanation:
Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.
Laguna del carbon, a salt lake located in. Argentina, lies 344 feet below sea level. El alto, Bolivia, is located approximately 13,000 feet above sea level. What is the difference in elevation Laguna del Carbon and El Alto?
Answer:
The difference in elevation between Laguna del Carbon and El Alto is 12,656 feet.
Step-by-step explanation:
Given that Laguna del carbon, a salt lake located in Argentina, lies 344 feet below sea level, while El Alto, Bolivia, is located approximately 13,000 feet above sea level, to determine what is the difference in elevation between Laguna del Carbon and El Alto, the following calculation must be performed:
13,000 - 344 = X
12.656 = X
Thus, the difference in elevation between Laguna del Carbon and El Alto is 12,656 feet.
Answer:
The Lowest place above sea level in the Americans.

The creators of a new organic drain cleaner claim that it is more effective at reducing clogs over the long term than a general soap solution. An
Independent group recently tested the cleaner to determine whether the claims are true. Three hundred households participated and were
divided into three equal-sized groups. Half of each group was randomly chosen to use the new cleaner, and half was assigned the soap solution
The households in each group used their given method for a year. This table shows the number of households that reported a reduction in clogs
in each group

the development of clogs is true.
There is not enough information to validate or

The organic drain cleaner's claim to be more
effective than the soap solution in reducing
the development of clogs is false.
Answer: group A: The organic drain cleaners claim to be more effective than the soap solution is reducing the development of clogs is false.
group B: The organic drain cleaners claim to

An electronic device factory is studying the length of life of the electronic components they produced. The manager selects two assembly lines and takes all samples on those two lines. He got a sample of 500 electronic components and records the length of life in the life test. A histogram indicates that the lifespans have moderate right skew. From the sample he found the average length of life was 200,000 hours and that the standard deviation was 1,000 hours. He wants to find the confidence interval for the average length of life of the electronic components they produced. Based on the information, what advice will you give to him
Answer:
The confidence interval will be given by:
[tex]200000 \pm 44.72z[/tex], in which z is related to the confidence level.
For a confidence level of x%, z is the value in the z-table that has a pvalue of [tex]1 - \frac{1 - z}{2}[/tex]
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In the context of this problems:
It means that the sampling distributions of the sample mean of 500 components will be approximated normal, with mean 200,000 and standard deviation [tex]s = \frac{1000}{\sqrt{500}} = 44.72[/tex]
To build the confidence interval:
The confidence interval for the average length of life of the electronic components they produced will be given by:
[tex]200000 \pm 44.72z[/tex], in which z is related to the confidence level.
For a confidence level of x%, z is the value in the z-table that has a pvalue of [tex]1 - \frac{1 - z}{2}[/tex]

Factor the algebraic expression below in terms of a single trigonometric function.
sin 2x + sin x - 2 (2 points)
We know that sin (2x) = 2 sinxcosx.
So, sin (2x) + sin (x) - 2 becomes
2sin xcosx + sinx- 2.
Factor out sinx.
sinx(2cosx + 1 - 2)
sinx(2cosx - 1)

The Hu family goes out for lunch, and the price of the meal is $54. The sales tax on the meal is 7%, and the
family also leaves a 15% tip on the pre-tax amount. What is the total cost of the meal?
Answer:
The total cost of meal is $65.34
Step-by-step explanation:
Price of the meal = $54
Sales tax on meal = 6%
Tip given= 15% on pre-tax amount
We need to find total cost of meal.
First finding sales tax amount:
We need to calculate 6% of 54

So, the sales tax would be $3.24
Now, we need to find tip amount
We will find 15% of 54

So, the tip given would be $8.1
The total cost of meal = Price of meal + Sales Tax + Tip
= 54+3.24+8.1
= 65.34
So, the total cost of meal is $65.34
