Answer:

22.22%

Step-by-step explanation:

A students spent 2 hours studying, 1 hour doing laundry, and 1\frac{1}{2} hours ( \frac{3}{2} hours) watching television.

Total time spent = 2 + 1 + \frac{3}{2}

                            = 3 + 1.5

                            = 4.5 hours

Now percent of time spent in doing laundry = \frac{1}{4.5} × 100

= 22.22%

He spent 22.22% time in doing laundry.

The table shows the results of a poll of 200 randomly selected juniors and seniors who were asked if they attended prom. Find th
Zielflug [23.3K]

Answer:

(a)\frac{7}{25}

(b)\frac{19}{116}

(c)\frac{28}{125}

Step-by-step explanation:

Number of juniors who attended prom,n(J)=28

Number of seniors who attended prom,n(S)=97

  • Total of those who attended prom=125

Number of juniors who did not attend prom,n(J')=56

Number of seniors who did not attend prom,n(S')=19

  • Total of those who attended prom=75
  • Total Number of students=200

(a) P (a junior who did not attend prom)

P(J')=\frac{56}{200}= \frac{7}{25}

(b)

P(Senior)=\frac{116}{200}

P ($did not attend prom$ | senior)=\frac{\text{P(seniors who did not attend prom)}}{P(Senior)} \\=\frac{19/200}{116/200} \\=\frac{19}{116}

(c)P (junior | attended prom)

P(Senior)=\frac{84}{200}

P (Junior|$ attended prom$)=\frac{\text{P(juniors who attended prom)}}{P(\text{those who attended prom)}} \\=\frac{28/200}{125/200} \\=\frac{28}{125}

What is the difference between a copyright and a trademark, and how are they used to protect intellectual property?
kirill [66]

Answer: Copyright protects original work, whereas a trademark protects items that distinguish or identify a particular business from another.

The trademark laws protect the product or service name and any slogans used in the advertising, while the copyright laws protect the additional creative written expression contained in the ad. Hope this helps!

The surface area of the world is about 7/10 water. If a very small, non-dangerous meteoroid lands on the earth, what is the prob
galben [10]

Answer: 3/10 probability

Step-by-step explanation:

We are telling the probability with tenths, so we can say that the probability of the meteoroid landing on Earth is 3/10.

If the surface area of the world is approximately 7/10, or 70 percent, water, there is approximately 3/10, or 30 percent, chance of the meteoroid hitting land.

I'm pretty sure, at least ^_^

Which graph represents the function f(x)=(x-5)^2+3
hammer [34]

Answer:

Parabola

Step-by-step explanation:

We are given that a function

f(x)=(x-5)^2+3

The given function is an equation of parabola along y- axis.

General equation of parabola along y- axis  with vertex (h,k) is given by

(y-k)=(x-h)^2

y=(x-h)^2+k

Compare it with given equation then we get

h=5, k=3

Vertex of given parabola =(5,3)

Substitute x=0 then we get

f(0)=(0-5)^2+3=28

y-intercept of parabola is at (0,28).
