Answer:

Sammy would have 16 friends.

Step-by-step explanation:

Let total number of friends be x, each friend gets 2 balls, this can be denoted as 2x balls.

The final relation can be expressed as:

40 (total number) =2x+8 , here 8 is the remainder after distribution.

Now we can solve for x

40=2x+8

40−8=2x

32=2x

x=16

Answer:

16 friends

Step-by-step explanation:

40 balls - 8 remaining = 32 balls in total

32 b in total / 2 balls each = 16 friends

hope this helps

Answer:

0.199

Step-by-step explanation:

p = 33% = 0.33

1 - p = 1 - 0.33 = 0.67

Using binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 2) = 10C2 * 0.33^2 * 0.67^8

P(x = 2) = 45 * 0.1089 * 0.0406067677556641

P(x = 2) = 0.19899346538663192205

P(x = 2) = 0.1989

P(x = 2) = 0.1990

Answer: I would say 6 its a function and 7 its not because in number seven the x value repeats so it can't be a function and number 6 the x-value its not the same

Step-by-step explanation: When the x-value repeats its not a function if the y-value repeats it doesn't matter

Answer: [tex]28.3\ hr[/tex]

Step-by-step explanation:

Given

Charge of the site visit [tex]\$45[/tex]

Additional charge per hour is [tex]\$24\ \text{per hour}[/tex]

He eaned [tex]\$810[/tex]

Suppose he worked for x hours

[tex]\therefore 810=45+24x\\\text{On solving}[/tex]

[tex]\Rightarrow 765=24x\\\Rightarrow x=28.3\ hr[/tex]

Answer:

13.7

Step-by-step explanation:

c^2 - b^2 = a^2

16.5^2 - 9.2^2 = a^2

272.25 - 84.64 = square root of a

square root of 187.61

= about 13.66 or 13.7

Answer:

The median

Step-by-step explanation:

If you look at the sample section of the 5 different prices, you can see that $2,000 is very far away from the rest of the prices, which range from $14,000 to $17,000. This $2,000 is an outlier, and is likely not accurate in predicting reasonable prices for Hank's bike, so it should not be a factor in his decision or contribute to the mean value.

Answer:

1 group of 7

Step-by-step explanation:

Answer:

The probability that two of them

die is 0.257

Step-by-step explanation:

From the question, we have that the mortality rate is 0.1

So the probability that they will survive is 1-0.1 = 0.9

Now, we want to check that two will die

We are going you use the Bernoulli approximation of the Binomial theorem as follows

= nCr * p^n * q^(n-r)

where n = 16

r = 2

P = 0.1

q = 0.9

Substituting these values;

14 C 2 * 0.1^2 * 0.9^12

= 0.257

Given:

The set is:

[tex]\{2,3,5,7,11\}[/tex]

To find:

The set builder notation for the given set.

Solution:

Consider the given set:

[tex]S=\{2,3,5,7,11\}[/tex]

The element of given set are 2, 3, 5, 7, 11 and so on. These area the prime numbers.

If x defines each element of the set then x must belongs to P which is the set of prime numbers. So, the given set can be written as

[tex]S=\{x|x\in P\}[/tex]

Therefore, the set builder notation for the given set is [tex]\{x|x\in P\}[/tex].

Answer:

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

Here, we want to get the number of times the graph of the function intersects the x-axis

Mathematically we need to know the number of roots the function has

We can get this by the use of the discriminant

This is:

D = b^2 - 4ac

b is the coefficient of x which is 0 here

a is the coefficient of x^2 which is 1 here

c is the last number which is 2

So;

D = 0^2 -4(1)(2) = 0-8 = -8

the discriminant value is negative

This means there are no real roots

x-y plane is used for real numbers and thus since there are no real roots, the graph of the equation will not intersect any point on the x-axis

Step-by-step explanation:

Technically if it is 10 out of 10 girls that likes pizza then that is 100%.

Answer:

The statement is false.

Step-by-step explanation:

Here we need to remember some things:

Integer numbers are closed under multiplication.

This means that for two integers a and b, the product a*b is also an integer.

A rational number is a number that can be written as the quotient of two integer numbers.

An irrational number is a number that can't be written as the quotient of two rational numbers.

Now let's see the statement:

"The product of two rational numbers is irrational."

The product of two rational numbers is written as:

[tex]\frac{a}{b} *\frac{c}{d}[/tex]

Where a, c, b, and d are integers.

We can rewrite that product as:

[tex]\frac{a*c}{b*d}[/tex]

Because of the first property, we know that a*c is an integer, and b*d is also an integer, so here we have a quotient of two integer numbers, so this is a rational number.

Then the product of two rational numbers is a rational number.

Then the statement is false.
