Ten cards numbered 1 through 10 are mixed together and then one card is drawn. Find the probability of each event. Write each answer as a fraction, percent, and decimal. P(less than 5) P(greater than 3) P(odd) P(even) P(not a multiple of 4) P(not 5, 6, 7, or 8) P(divisible by 3)

Answers

Answer:

2/5, 0.4, 40%

7/10, 0.7, 70%

1/2, 0.5, 50%

1/2, 0.5, 50%

4/5, 0.8, 80%

3/5, 0.6, 60%

3/10, 0.3 ; 30%

Step-by-step explanation:

Sample space = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

P(less Than 5) :

Required = (1, 2, 3, 4) = 4 observations

P(less than 5) = 4 / 10 = 2 / 5 = 0.4 = 40%

Greater than 3) = (4, 5,6,7,8,9,10) = 7 observations

P greater Than 3) = 7/10 = 0.7 = 70%

Odd = (1,3,5,7,9) = 5

P(odd) = 5 / 10 = 1/2 = 0.5 = 50%

(even) = (2,4,6,8,10) = 5

P(even) = 5 / 10 = 1/2 = 0.5 = 50%

Not a multiple of 4 = (1,2, 3,5,6,7,9,10) = 8

P(not A multiple of 4) = 8/10 = 4/5 = 0.8 = 80%

not 5, 6, 7, or 8 = (1,2,2,4,9,10).= 6

P(not 5, 6, 7, or 8) = 6 / 10 = 3/5 = 0.6 = 60%

Divisible by 3 = (3, 6, 9) = 3

P(divisible by 3). = 3/10 = 0.3 = 30%

Kahlid wants to buy a board game that costs Rs 501. He has Rs 479. How much more money does he need?

Required

The amount needed

The saved amount when added to amount needed (x) must equal to the price of the game

i.e.

S ≈ 19.0

Step-by-step explanation:

The angles of the triangle are 90, 43, and 47. Given these we can apply the law of sines.

26/sin(90) = s/sin(43), giving you 17.73195, rounding to 17.7.

26/sin90 = r/sin(47), giving you 19.01519, rounding to 19.0.

Answer:

x=8 and QNR= 63°

Step-by-step explanation:

90+8x-1+27=180

116+8x=180

8x=64

x=8

Answer:

8, m<QNR=63 degrees

Step-by-step explanation:

So, lets go over what we know:

The angle that makes up (8x-1) and 27 degrees is a right angle.

A right angle is 90 degrees.

So, to solve for angle m<QNR and for x, we must subtract and solve using 27 degrees, and (8x-1).

Lets put this into equation form:

(8x-1)+27=90

Lets subtract 27 from both sides to get the (8x-1) alone:

(8x-1)=63.

So lets stop here real quick.

We need to find angle M<QNR. This is (8x-1)

So looking at what we have solved so far, angle M<QNR must be 63 degrees.

Now, lets solve further to find out what x is:

(8x-1)=63

Lets add x to both sides to get 8x alone:

(8x)=64

We dont need the parethese, for they do not have a function, so:

8x=64

Finally, lets divide 8 from both sides so we can make 8x into just x:

x=8

So x is equal to 8.

Overall:

x = 8

Angle m<QNR = 63

the surface area of earth is about 196.9 million square miles. The land area is about 57.5 million square miles, and the rest is water. What is the probability that a meteorite that reaches the surface of earth will hit land

Answers

Answer: 29.2%

Step-by-step explanation:

The total surface area is 196.9 million square miles and out of this, land occupies 57.5 million square miles.

The probability that a meteorite would hit land is the percentage of and out of the entire planet area:

= Land area/ Total earth surface area

= 57.5/ 196.9

= 29.2%

Write the equation in slope intercept form?

Answers

Answer:

A

Step-by-step explanation:

The linear equation in two variables is given to us is

→ y = 3( x -4) +6x

Slope Intercept Form :-

The slope intercept form of the equation is y = mx + c .

→ y = 3x - 12 + 6x

→ y = 6x + 3x -12

→ y = 9x - 12

Hence the correct option is A .

5x = 150

x = 30

3(30) + 2(30) = 150

                      90/60=1.5

PLEASE HELP ME W A MATH PROBLEM!!!

Answers

Answer:

A) 296

Step-by-step explanation:

we have to find the angle of angle 5 since we know angle 6. Angle 6 is 32 so we will subtract 32 from 180 since straight lines are 180 degree angles (even though it doesn't look like one). This will give us 148. Since angle 5 and 4 are alternate interior angles, they have the same angle measurements. 148 + 148 = 296. Thus, angle 5 + angle 4 = 296 degrees.

It would be 148. I believe so because I already did this!
