Suppose X∼N(12.5,1.5), and x=11. Find and interpret the z-score of the standardized normal random variable.\

Answer:  D) Van: 8, Bus: 25

Bus can carry 25 students ,  van can carry 8 students.

Explanation:

Let vans be v and buses be b

Equations:

6v + 2b = 98 ..........from Theory 1

10v + 2b = 130 ..........from Theory 2

Making b the subject:

6v + 2b = 98

b = (98 - 6v)/2 ............. equation 1

10v + 2b = 130

b = (130 - 10v)/2  .........equation 2

Solving them simultaneously:

(130 - 10v)/2 = (98 - 6v)/2

130 - 10v = 98 - 6v

-6v + 10v = 130 - 98

4v = 32

v = 8

Therefore each van can carry 8 students.

Then the bus can carry: (98 - 6v)/2

                                    → (98 - 6(8))/2

                                    →  25 people

Hey there, hope you are having a nice day! :)

5 less than 25 simply means we subtract 5 from 25.

Now, let's write it as a numerical expression (let's express it in numbers)

Answer:

sum means addition. meaning that to find this sum of a number we can subtract 12 3/4 from 16 4/9. we get 3 25/36.

we know this is the actual answer bc 12 3/4+ 3 25/36=16 4/9

Step-by-step explanation:

Answer:

Domain: [tex][-2,1)[/tex]

Range: [tex][0,4][/tex]

Step-by-step explanation:

Domain

We can see that the piecewise function starts at x=-2, which is included, and ends at x=1, which isn't included. To represent the x-values that lie in between these two endpoints, you would write [tex][-2,1)[/tex]. Brackets show that one endpoint is included while parentheses show that one endpoint isn't included.

Range

Following this logic, the range has its y-values go from 0 to 4 with both endpoints included if you were to trace the function. Thus, your range would be [tex][0,4][/tex].

The value of the missing angle is [tex]34.1^{o}[/tex]. Option C.

Trigonometric functions are a set of functions which can be used to determine the value of an unknown side or angle of a given right triangle.

To determine the missing angles, we have;

sin x = opposite/ hypotenuse

Answer:

Your answer is 114.

Step-by-step explanation:

Since theres 342, and 6 pounds try to see what each pound equals first. Try to divide 342 in half, which gets you 171 one third of 171 is 57. So your answer is 57. To check your answer 57 x 3 would get 171. 171 x 2 would get you 342 so your answer is 57 + 57 = 114

Answer:

x = -1.4375

Step-by-step explanation:

Multiply the monomials: 40x + 7 = 24x - 16

Rearrange unknown terms to the left side of the equation: 40x-24x=-16-7

Combine like terms: 16x=-16-7

Calculate the sum or difference: 16x = -23

Divide both sides of the equation by the coefficient of variable: x = -23÷16

Calculate the product or quotient: x=-1.4375

Answer:

Option C.

Step-by-step explanation:

Shortest way to solve this question is to find the factors of the given expression.

The given expression is (x² + 13).

Now we have to factorize it.

(x² + 13) = x² + (√13)²

            = x² + [-(i)²√(13)²]  [Since i = √(-1)]

            = x² - (i√13)²

            = (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]

Option C will be the answer.
