The student scored 425 on the first test and 65 on the second test. Use z-scores to determine on which exam the student performed better relative to the other test takers. first exam

Answer:

y=-5/2x+1

Step-by-step explanation:

-1-4 ( -5 )

0- (-2 ) = 0+2 ( 2 )

-5/2

y=-5/2x+b

4=-5/2( -2 ) +b

4= 5+b

Subtract 4 from 5 ( 1 )

b=1

y=-5/2x+1

The equation of the line passing from the given points is y = -5x/2-1

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, a line is passing through two points (-2, 4) and (0 -1)

We know that, the equation of a line passing through two points is given by,

y-y₁ = (y₂-y₁/x₂-x₁)(x-x₁)

Therefore,

y-4 = (-1-4)/(0+2)(x+2)

y-4 = -5/2(x+2)

y = -5x/2-5+4

y = -5x/2-1

Hence, The equation of the line passing from the given points is y = -5x/2-1

Answer:

y = (5/3)x + 4

Step-by-step explanation:

-5x + 3y = 12 (What you start with)

3y = 12 + 5x (Adding 5x to both sides)

y = (5/3)x + 4 (Dividing the equation by 3)

[tex]x=21[/tex]

Step-by-step explanation:

See attachment for triangle

The relationship between length x, length 24 and angle 30 is as follows:

[tex]\cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]

In this question;

[tex]Adjacent = x[/tex]

[tex]Hypotenuse= 24[/tex]

[tex]\theta = 30[/tex]

Substitute these values in the above expression,

[tex]\cos(30) = \frac{x}{24}[/tex]

Multiply through by 24

[tex]24 * \cos(30) = \frac{x}{24} * 24[/tex]

[tex]24 * \cos(30) = x[/tex]

Reorder:

[tex]x = 24 * \cos(30)[/tex]

[tex]x = 24 * 0.8660[/tex]

[tex]x = 20.784[/tex]

Answer:

1 apple: 24 people

2 apples: 12 people

3 apples: 8 people

4 apples: 6 people

6 apples: 4 people

8 apples: 3 people

12 apples: 2 people

24 apples: 1 person

Step-by-step explanation:

The number of 6 people can have 4 apples each.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Priya is sharing 24 apples equally with some friends.

She uses division to determine how many people can have a share if each person gets a particular number of apples.

For example, 24 ÷ 4 = 6 means that if each person gets 4 apples,

then 6 people can have apples,

= 24 ÷ 6

= 4

Therefore, 6 people can have 4 apples.

Step-by-step explanation:

Given

Dogs : Cats = 2 : 3

Required

Determine the possible number of dogs and cats at the store

The question requires options; since there are none, I'll answer on a general terms.

We have the dog to cat ratio to be:

Dogs : Cats = 2 : 3

Multiply ratio by any number (say 7)

Dogs : Cats = 2 * 7 : 3 * 7

Dogs : Cats = 14 : 21

This means that if there are 14 dogs, then there are 21 cats.

Multiply the ratio by another number (say 4)

Dogs : Cats = 2 * 4 : 3 * 4

Dogs : Cats = 8 : 12

This implies:

8 dogs and 12 cats

In conclusion, the number of dogs, when divided by the number of cats must equal ⅔.

Answer:

So the first term is two so you start on the second term. 15,28,41

An arithmetic sequence having first term 2 and a common difference of 13 then the next terms are 15, 28 and 41.

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same constant ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, An arithmetic sequence having first term 2 and a common difference of 13.

Therefore the next terms are (2+13), (2 + 2×13), (2 + 3×13).

= 15, 28, and 41.
