To understand these questions, first look at the way the answers are written out.

Alia questions three students from her class, that might be an answer, but she didn't randomly pick them.

Miles randomly surveys a group of customers at a coffee shop, that might be one, but he might have surveyed a 25 year old instead of a 24 year old, so thats not one.  

Carson interviews students working part-time to gather data, he didn't select random students, he interviewed all of them, so that is not a valid option.

 Lea speaks with the managers at half of the town's 10 supermarkets, which stock similar items, to find out which breakfast cereal is most popular among the town's residents, that one is not stating that she interviewed, but she interviewed half of the 10, which is five, which can be selected randomly.

The fourth term of an arithmetic sequence is 20, and the 13th term is 65. Find the sum of the first 13 terms

Answers

Answer:

S₁₃ = 455

Step-by-step explanation:

the sum to n terms of an arithmetic is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

We require to find both a₁ and d

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

given a₄ = 20 and a₁₃ = 65 , then

a₁ + 3d = 20 → (1)

a₁ + 12d = 65 → (2)

subtract (1) from (2) term by term to eliminate a₁

9d = 45 ( divide both sides by 9 )

d = 5

substitute d = 5 into (1) and solve for a₁

a₁ + 3(5) = 20

a₁ + 15 = 20 ( subtract 15 from both sides )

a₁ = 5

Then

S₁₃ = [tex]\frac{13}{2}[/tex] [ (2 × 5 ) + (12 × 5 ) }

     = 6.5 (10 + 60)

Solutions of a quadratic function

From the question, we are to determine the number of real solutions the quadratic function has.

NOTE:

If the graph of the quadratic function crosses the x-axis at two points then we have two solutions. If the graph touches the x-axis at one point then we have one solution.If the graph does not intersect with the x-axis then the equation has no real solution.

From the given diagram, the graph of the quadratic function crosses the x-axis at two distinct points.

∴ The quadratic function has two real solutions

The solutions of a quadratic function are the points where the graph intersects with the x-axis.

In the given graph, the solutions to the function are x = -2 and x = 0

Hence, the quadratic function has two real solutions. The solutions to the function are x= -2 and x= 0.

Answer:

The given quadratic has two solutions.

Step-by-step explanation:

The discriminant of a quadratic equation is [(b^2) - (4 * a * c)]

We're given the quadratic x^2 - 8x - 84 = 0

We can find a, b, and c by analyzing the quadratic.

So,

a = 1 because x^2 has no coeffiecient

b = -8 ( coefficient of 8 * the - )

c = -84 the raw y-intercept value of this function

Now we can plug these numbers into the discriminant expression:

(-8)^2 - ( 4 * 1 * -84 ) =

64 - ( - 336 ) =

64 + 336 =

400

Now that we know the value of the discriminant, we have to anazlyze it.

If the discriminant of a quadratic is positive, the quadratic has 2 solutions.

If the discriminant is negative, the quadratic has no solutions.

If the discriminant is equal to zero, the quadratic only has 1 solution.

In conclusion, because the discriminant = 400, and 400 > 0, the given quadratic equation has two solutions.

Find pairs of the above factors, which, when multiplied equal 84.
{1*84,2*42,3*28,4*21,6*14,7*12}

Which pairs of these factors have a difference of B = -8?

Find the solutions of the quadratic equation –9x2 + 49 = 0.

Answers

Answer:

x = 7/3

Step-by-step explanation:

Given equation:

–9x² + 49 = 0

To determine the value of "x", we need to isolate the x-variable and it's coefficient on one side of the equation. This can be done by subtracting 49 to both sides of the equation.

⇒ –9x² + 49 - 49 = 0 - 49⇒ –9x² = -49

We can see that the negative sign in on both sides of the equation. Remove it by dividing -1 to both sides of the equation.

⇒ –9x² = -49⇒ -9x²/-1 = -49/-1⇒ 9x² = 49

Clearly, we can see that 9x² and 49 are perfect squares. Therefore,

⇒ 9x² = 49⇒ (3x)² = (7)²

Take square root both sides of the equation:

⇒ √(3x)² = √(7)²⇒ 3x = 7

To determine the value of "x", we need to isolate it "completely". This can be done by dividing 3 to both sides of the equation

⇒ 3x/3 = 7/3⇒ x = 7/3

Therefore, the value of "x" must be 7/3.

Answer:

x = 7∕3, –7∕3

Step-by-step explanation:

To find the solutions of the quadratic equation -9x^2 + 49 = 0, we can solve for x by isolating x^2 first:

-9x^2 + 49 = 0

-9x^2 = -49

Dividing both sides by -9, we get:

x^2 = 49/9

Taking the square root of both sides, we get:

x = ± 7/3

Therefore, the solutions of the quadratic equation -9x^2 + 49 = 0 are x = 7/3 and x = -7/3.

Answers

Answer:

ΔABC is a right triangle

length of the concession stand = 42.4 ft (nearest tenth)

Step-by-step explanation:

Given:

Side length of square A = 30 ftSide length of square B = 40 ftSide length of square C = 50 ft

We can use Pythagoras' Theorem to prove if ΔABC is a right triangle.

Pythagoras' Theorem: a² + b² = c²  (where a and b are the legs, and c is the hypotenuse of a right triangle)

Given:

a = side length of square A = 30b = side length of square B = 40c = side length of square C = 50

⇒ a² + b² = c²

⇒ 30² + 40² = 50²

⇒ 900 + 1600 = 2500

⇒ 2500 = 2500

Therefore, ΔABC is a right triangle

To find the diagonal of square A, use Pythagoras' Theorem:

Given:

a = side length of square A = 30b = side length of square A = 30c = diagonal of square A

⇒ a² + b² = c²

⇒ 30² + 30² = c²

⇒ 900 + 900 = c²

⇒ c² = 1800

⇒ c = √(1800)

⇒ c = 42.42640687

Therefore, the length of the concession stand (diagonal of square A) is 42.4 ft (nearest tenth)

The average of the test scores of a
group of x students is 76 and the average of the test scores of a group of y students is 90. When the scores of the two groups of students are combined, the average test score is 85. What is the value of x/y

Answers

Answer:

x/y = 5/9

Step-by-step explanation:

sum = count * mean

for the group of x students:

sum = x * 76

let's say this sum is a

a = 76x

for the group of y students:

sum = y * 90

let's say this sum is b

b = 90y

total sum = total count * total mean

total sum = total sum from both groups = a + b

total count = total count from both groups = x + y

a + b = (x+y) * 85

expand

a + b = 85x + 85y

a = 76x

b = 90y

replace a with 76x and b with 90y in the first equation. this limits the equation to x and y, which we want because we want to find x/y

76x + 90y = 85x + 85y

subtract 76x and 85y from both sides to limit the amount of numbers

5y = 9x

divide both sides by 9 to isolate the x

(5/9)y = x

divide both sides by y to get x/y

x/y = 5/9
