King, a golden retriever, can find a tennis ball hidden in his yard 89% of the time, while Tessa, a Labrador mix, can find a tennis ball hidden in her yard 94% of the time. Suppose King’s owner hides a tennis ball in his yard 100 times and Tessa’s owner hides a tennis ball in her yard 150 times. Let K = the proportion of times King finds the tennis ball and T = the proportion of times Tessa finds the tennis ball. What is the probability that the proportion of tennis balls King finds is greater than the proportion Tessa finds?

A) 0.050
B) 0.088
C) 0.476
D) 0.912

Answer:

9/35.............,..........

Answer:

1/5

Step-by-step explanation:

2/5 - 1/7 = ???

find the least common denominator!

45 would be the least common demoninator!

so...

2 (7) / 5(7) - 1 (5) / 7 (5) = ?

14/ 45 - 5 /45 = ?

14 - 5 = 9

9/45. Simplify!

9/45 divide 9 from both sides

9/9 /  45/9

= 1/5, one fifths is your answer!

Answer:

1. m∠1 = 48°

2. m∠1 = 129°

3. m∠1 = 37°

4. m∠1 = 88°

m∠2 = 42°

m∠3 = 113°

5. m∠1 = 72°

m∠2 = 35°

m∠3 = 24°

6. m∠1 = 128°

m∠2 = 52°

m∠3 = 47°

m∠4 = 133°

m∠5 = 81°

7. m∠1 = 41°

m∠2 = 85°

m∠3 = 95°

m∠4 = 85°

m∠5 = 36°

m∠6 = 49°

m∠7 = 106°

8. x = 12°

9. x = 9°

10. x = 5°

11. x = 7°

Step-by-step explanation:

1. 76° + 56° + m∠1 = 180°

∴ m∠1 = 180° - (76° + 56°) = 48°

m∠1 = 48°

2. m∠1 = 67° + 62° = 129°

m∠1 = 129°

3. m∠1 = 152° - 115° = 37°

m∠1 = 37°

4. m∠1 = 180° - (52° + 42°) = 88°

m∠1 = 88°

m∠2 = 42°

m∠3 = 180 - (42° + 25°) = 113°

m∠3 = 113°

5. m∠1 = 180° - 118° = 72°

m∠1 = 72°

m∠2 = 180° - 72° - 73° = 35°

m∠2 = 35°

m∠3 = 73° - 49° = 24°

m∠3 = 24°

6. m∠5 = 180° - m∠52° - m∠47° = 81°

m∠5 = 81°

m∠1 = 81° + 47° = 128°

m∠1 = 128°

m∠2 = 52°

m∠3 = 47°

m∠4 = 180° - 47° = 133°

m∠4 = 133°

7. m∠3 = 95°

m∠5 = 180° - 144° = 36°

m∠5 = 36°

m∠6 = 180° - 95° - 36° = 49°

m∠6 = 49°

m∠4 = 180° - 95° = 85°

m∠4 = 85°

m∠2 = 85°

m∠7 = 360° - (38° + 85° + (180° - 49°)) = 106°

m∠7 = 106°

m∠1 = 360° - (85° + 90° + 144°) = 41°

m∠1 = 41°

8. (10·x - 11)° + (3·x - 2)° + (3·x + 1)° = 16·x° - 12° = 180°

16·x = 180°+ 12° = 192°

x° = 192°/16 = 12°

x = 12°

9. (3·x - 5)° + (7·x + 5)° + 90 = 180°

10·x + 90° = 180°

10·x  = 180°- 90° = 90°

10·x = 90°

x = 90°/10 = 9°

x = 9°

10. 180 - 151 = 29°

(11·x - 1)° + (20·x - 3)° + 29° = 180°

31·x° + 25° = 180°

31·x°  = 180° - 25° = 155°

31·x°  = 155°

x = 155/31 = 5°

x = 5°

12. (4·x + 13) + (6·x + 2) + 180 - (14·x - 13)

208° - 4·x° = 180°

208° -  180° = 4·x°

28° = 4·x°

4·x° = 28°

x = 28°/4 = 7°

x = 7°.

Step-by-step explanation:

Amount of milk = 1/ 3 l

No: of mugs = 4

Amount in each mug =  1/3 ÷ 4 = 1/3 x 1/4 = 1/12 l  

(Hope its right!)

Answer:

They will have 1/12 of a liter of milk on each mug because you are dividing 1/3 into 4 so the denominator is multiplied by 4

Actually Welcome to the Concept of the Functions.

Since, the above function is a square root function, we must always keep it's domain as Positive Real numbers, such that it will not went to the imaginary axis, hence

D: R+

Range, for range we equate it to 0 ,

hence we get as,

R: x belong from 0 to positive Infinite

As, x---> infinite, f(x) ---> - infinite

As, x----> 0 , f(x) -----> 0

increasing interval, we have to differentiate it, we get as

-4 to 0

Decreasing interval is 0 to infinite

Hey there!

The answer is [tex]9[/tex]

We will start by forming an equation to solve this.

So we are starting with a number, [tex]x[/tex], then doubling it and adding [tex]7[/tex], which gives us 25.

So:

[tex]2x+7=25[/tex]

Now we solve this equation:

[tex]2x+7=25[/tex]

[tex]2x=18[/tex]

[tex]x=9[/tex]

Have a super awesome day!

Answer:

X = 9

Step-by-step explanation:

If you take 9, then double it, you get 18. 9+9 = 18. Then, you would add 7. 18 plus 7 is 25.

Hence, the answer to this problem is 9.

Answer:

Step-by-step explanation:

Alright so the step that comes first is adding two to both sides.

Let me show you,

Step 1

-b-2<8  Add 2 to both sides

-b<10

Then you divide the sides by -1

-b<10

b>-10

[tex]m= 14 \sqrt 2, \: n = 14[/tex]

Step-by-step explanation:

Hope it helps you in your learning process.

Given is a 45°-45°-90° triangle.

Measure of sides n and 14 are opposite to 45° degree angles.

Therefore, they are equal.

So, n = 14

[tex] 14 = \frac{1}{\sqrt 2}\times m[/tex]

[tex] 14 \sqrt 2=m[/tex]

Answer:

x = 18

Step-by-step explanation:

5x/9 = x/6 + 7

multiply both sides by 9

5x = 9x/6 + 63

multiply both sides by 6

30x = 9x + 378

subtract 9x from each side

21x = 378

divide both sides by 21

x = 18

check by substituting 18 for x:

5(18)/9 = 18/6 + 7

5(2) = 3 + 7

10 = 10
