I'm doing theoretical probobility. Can you help me with this problem. It says to write it is a fraction, decimal, and a percent.

Alchen [17]

So probability is (disred outcomes) divided by (total possible outomces

so
hearts and clubs are 2 out of 4 total suits and since there are the same number of cards per suit, it simplifies
2=desrired oucomes
4=total possible
2/4=1/2=0.5=50%

answer is 1/2 or 0.5 or 50%

Find each measurement indicated. Round your answers to the nearest tenth. Please show your work. Part 2

uysha [10]

Answer:

4. 14.03 miles

5. 15.02 kilometers

6. 19.95 meters

Step-by-step explanation:

4. We need to use the law of sines, which states that for a triangle with angles A, B, and C and sides a, b, and c, respectively, then:

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Here, a = 30, <A = 130, and <B = 21. So, let's plug these in:

$\frac{30}{sin130} =\frac{b}{sin21}$

b = AC = $\frac{30}{sin130}*{sin21}$ ≈ 14.03 miles

5. Here, c = 7, <C = 23, and <A = 123. We want to find BC, which is just a:

$\frac{7}{sin23} =\frac{a}{sin123}$

a = BC = $\frac{7}{sin23} *{sin123}$ ≈ 15.02 kilometers

6. Here, c = 22, <C = 88, and <B = 65. We want to find AC, which is just b:

$\frac{22}{sin88} =\frac{b}{sin65}$

b = AC = $\frac{22}{sin88} *{sin65}$ ≈ 19.95 meters

Hope this helps!

A survey asked participants whether or not they were vegetarian and how important they thought saving energy was. The two-way ta

blondinia [14]

Answer:

We choose D.

Step-by-step explanation:

The question is which statement is true?

A. 33% of the people surveyed were vegetarian and though saving energy was not important

=> It is wrong because we do not know the total number of people who were surveyed.

B. This statement is wrong, because we also have 26% non - vegetarian though saving energy was not important

C. This statement is wrong, because there are 38% non - vegetarian though saving energy was not important and only 26% non - vegetarian though saving energy was very important

D. True because there are 36% non - vegetarian though saving energy was somewhat important while there are 17% vegetarian think so. Hence, a person who was not a vegetarian was morel likely than a vegetarian to think that saving energy is somewhat important

=> We choose D.

Rus_ich [418]

slope is just "how much up or down" for one step to the right.

its clearly negative here

only -3 seems to be remotely plausible looking at the graph in your screenshot
