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.
So the correct answer is D.

Answer:
g(x) = 10(x +1)² +5
Step-by-step explanation:
When a point is translated 3 units down, its y-value is 3 less than it was. The graph of f(x) is translated 3 units down by subtracting 3 from the value of f(x).
g(x) = f(x) -3 . . . . . translates f(x) 3 units down
__
For f(x) = 10(x +1)² +8, we want ...
g(x) = f(x) -3 = (10(x +1)² +8) -3
g(x) = 10(x +1)² +5
Translation of 3units down means change in y axis
y is decreased by 3
Hence new equation

Find the solutions of the quadratic equation –9x2 + 49 = 0.
Answer:
x = 7/3
Step-by-step explanation:
Given equation:
–9x² + 49 = 0To 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 = -49We 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 = 49Clearly, we can see that 9x² and 49 are perfect squares. Therefore,
⇒ 9x² = 49⇒ (3x)² = (7)²Take square root both sides of the equation:
⇒ √(3x)² = √(7)²⇒ 3x = 7To 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 = 7/3Therefore, 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.

Which statement best describes the streams on either side of the Great Divide?
They feed different water sheds.
They channel rain to the Pacific Ocean.
They flow into the same drainage basin.
They have some of the same large rivers.
Explanation:
The Great Divide commonly refers to the continental divide of North America. The watersheds of the Pacific Ocean are separated from the Atlantic Ocean by the Great Divide. Green River watershed is located to the west of the endorheic basin, and it is drained to the Gulf of California/Pacific Ocean.
The water flowing to the Pacific Ocean is separated from the water flowing to the Southern and Indian Oceans. Various
water sheds can be efficiently fed through Great Divide.
The water is gathered and depleted into water bodies like waterway, lake or stream correct answer is option C i.e. They flow into the same drainage basin.
What is the purpose of drainage i the Great Divide??The land region which gathers water is likewise called a drainage bowl or catchment region. It monitors water, advances the proceeded with stream of the waterway. It helps in the amassing of groundwater, empowers solid soil and furthermore gives territory to untamed life and plants.
Here, we have,
A drainage bowl addresses the land region which is contributing water to a stream. The water commitment can be straightforwardly toward a solitary stream, or toward a few streams that stream into a bigger, focal stream.

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.

Traci will be 360 miles in 12 hours if the linear equation y = 30x describes how far from home Traci is as she drives from Dallas to Anchorage and the equation of the graph is linear.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have a linear equation:
y = 30x
Here, x represent the number of hours and y represent the number of miles.
When x = 12 hours then
y = 30(12) = 360 miles
If draw the graph the equation y = 30x, it will be a linear equation.

Estimate the length of the concession stand to determine if the school banner can fit across the length of the concession stand. Show your work and explain your reasoning. (2 points)
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 ftWe 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
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
