Answer:

  D)  Happy snakes are not purple

Step-by-step explanation:

The first statement tells us all happy snakes can add.

The second statement tells us that all purple snakes can't subtract, and the third statement tells us that purple snakes also cannot add.

Therefore, we must conclude that happy snakes are not purple.

Answer:

  7x +8y = 32

Step-by-step explanation:

Clear fractions and add the opposite of the x-term.

  y = -7x/8 +4

  8y = -7x +32 . . . . . multiply by 8

  7x +8y = 32 . . . . . .add 7x

Answer:

0.036

Step-by-step explanation:

Answer:

0.24 x 0.15 = 0.036

Step-by-step explanation:

First ignore the decimal points so you have 24*15 = 360.

You have to start at the right, and move the decimal point 4 places. So, you get 0.036. Pls give brainliest.

Answer:

The average number of skiers in Lavilla are 1,600 skiers

Step-by-step explanation:

The number of skiers that come to Lavilla on average each week = 2,800 skiers

The number of days each skier stays in Lavilla = 4 days

The amount each skier spends in local restaurants daily = $40

According to Little's Law, we have;

L = λ·W

Where;

L = The average number of skiers in Lavilla

λ = The effective arrival rate of the skiers = 2,800 skiers per week arrive

W = The number of days each skier stays at Lavilla = 4 days = 4/7 week

The average number of skiers in Lavilla, 'L', is therefore, given as follows;

L = 2,800 skiers/weel × (4/7) week = 1,600 skiers

The average number of skiers in Lavilla, L = 1,600 skiers

Answer:

just divide 18 by 1920 duh

Step-by-step explanation:

Answer:

a) The percentage that the student does not read any paper is  10%  

b) The percentage that the student reads the local paper is 40%

c) the percentage that the student reads exactly two papers is 23%

d) the percentage that the student reads at least two papers is 25%

Step-by-step explanation:

Given the data in the question;

as illustrated in the Venn diagram below,

a)The student does not read any paper;

The percentage that the student does not read any paper will be;

100% - 90% = 10%

Therefore, The percentage that the student does not read any paper is  10%  

b) The percentage that the student reads the local paper;

from the Venn diagram below;

⇒ ( 20 + 15 + 3 + 2 )%    

= 40%

Therefore, The percentage that the student reads the local paper is 40%

c) The percentage that the student reads exactly two papers

⇒ ( 15 + 5 + 3 )%

= 23%

Therefore, the percentage that the student reads exactly two papers is 23%

d) The percentage that the student reads at least two papers;

⇒( 15 + 5 + 3 + 2 )%      

= 25%

Therefore, the percentage that the student reads at least two papers is 25%

Answer:

40%

Answer:

  x = 10°; angles are 50°, 46°, 84° (CW from left)

Step-by-step explanation:

The sum of the three angles is 180°, so ...

  (6x +10°) +(4x +6°) +(7x +14°) = 180°

  17x +10° = 180°

  17x = 170°

  x = 10°

__

Then the angles are ...

  6x -10° = 6·10° -10° = 50°

  4x +6° - 4·10° +6° = 46°

  7x +14° = 7·10° +14° = 84°

Answer:

You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

Answer:

We have strong evidence that on average, students study less than 150 minutes per night during the school week

Step-by-step explanation:

Normal distribution:

mean     μ₀ = 150

Sample:

Sample size    n = 272

Sample mean   x = 141

Sample standard deviation  s  = 66

The standard error of the sample mean  SE = σ /√n

SE = 66/√272

SE = 66 / 16,49

SE = 4

Test Hypothesis:

Null hypothesis                            H₀             x  =   μ₀

Alternative hypothesis                Hₐ            x <    μ₀

z(s)  test statistics is:

z(s)  =  ( x  -  μ₀ ) / s/√n

z(s) = - 9 /4

z(s) =  -  2,25

p-value  for that z(s)      p-value  = 0,0122

Then for α =  0,05 p-value < 0,05

We are in the rejection region we need to reject H₀

Answer: 10/20 or 1/2

Step-by-step explanation:

10 is the half of twenty, if she’s gonna eat the rest, she’s gonna eat the other half

Santa ate 10/20. right?

so you would subtract 10 from 20

which would give you 10

so Mrs. Claus also ate 10/20

-----

Another way to solve:

since 10/20 = 50%

Mrs. Claus ate the same amount

because 50% is half of 100% ( 1 whole )

So, Mrs. Claus ate 10/20

Answer: 21

Step-by-step explanation:

84 divided by 4 = 21 since grabielle is 21, and then mikhail is gonna be 3 times more so it’s gonna be 63

Answer:

Mikhail=21

Gabrielle=63

Step-by-step explanation:

G=3M

G+M=84

G=84-M

3M=84-M

4M=84

M=21

G=63

Answer:

the answer is 1/2 or 0.5

Step-by-step explanation:

So basically you just get on a calculator and divide it after you do that it will give you a decimal and all you have to do is convert that decimal to a fractiom so we know that 0.5 is a half so therefore 0.5=1/4

Answer:

a) 0.0002 = 0.02% probability that all are silver.

b) 0.0033 = 0.33% probability that 5 are red and 2 are black

c) 0.0345 = 3.45% probability that 4 are red and the rest are silver

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order in which the cars were selected is not important, so we use the combinations formula.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

(a) all are silver

Desired outcomes:

7 silver cars, from a set of 9. So

[tex]D = C_{9,7} = \frac{9!}{7!(9-7)!} = 36[/tex]

Total outcomes:

7 cars from a set of 8 + 9 + 5 = 22. So

[tex]T = C_{22,7} = \frac{22!}{7!(22-7)!} = 170544[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{36}{170544} = 0.0002[/tex]

0.0002 = 0.02% probability that all are silver.

(b) 5 are red and 2 are black

Desired outcomes:

5 red, from a set of 8

2 black, from a set of 5

[tex]D = C_{8,5}*C_{5,2} = \frac{8!}{5!(8-5)!}*\frac{5!}{2!(5-2)!} = 56*10 = 560[/tex]

Total outcomes:

7 cars from a set of 8 + 9 + 5 = 22. So

[tex]T = C_{22,7} = \frac{22!}{7!(22-7)!} = 170544[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{560}{170544} = 0.0033[/tex]

0.0033 = 0.33% probability that 5 are red and 2 are black

c) 4 are red and the rest are silver

Desired outcomes:

4 red, from a set of 8

3 silver, from a set of 9

[tex]D = C_{8,4}*C_{9,3} = \frac{8!}{4!(8-4)!}*\frac{9!}{3!(9-3)!} = 70*84 = 5880[/tex]

Total outcomes:

7 cars from a set of 8 + 9 + 5 = 22. So

[tex]T = C_{22,7} = \frac{22!}{7!(22-7)!} = 170544[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{5880}{170544} = 0.0345[/tex]

0.0345 = 3.45% probability that 4 are red and the rest are silver

Answer:

(X)      0        1          2          3         4

P(X)   0.17   0.23    0.27    0.24    0.09

F(x)    0.17    0.04    0.65    0.91      1      

Step-by-step explanation:  

Given that;

(X)      0        1          2          3         4

P(X)   0.17   0.23    0.27    0.24    0.09

cumulative distribution function can be calculated by;  be cumulatively up the value of p(x) with the values before it;

so

x      F(x)

0     P(X = 0) = 0.17

1       P(X = 0) + P(X = 1) = 0.17 + 0.23 = 0.4

2      P(X = 0) + P(X = 1) + P(X = 2) = 0.17 + 0.23 + 0.27 = 0.65

3      P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.17 + 0.23 + 0.27 + 0.24 = 0.91

4      P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.17 + 0.23 + 0.27 + 0.24 + 0.09 = 1

Therefore, cumulative distribution function f(x) is;

(X)      0        1          2          3         4

P(X)   0.17   0.23    0.27    0.24    0.09

F(x)    0.17    0.04    0.65    0.91      1      

Answer:

Events A and B are independent if and only if P(A and B) = P(A)P(B). If you know these probabilities, you can check to see if this holds.
