Answer:
To find the y-intercept, graph the points, and draw a line that passes through them. the place that it passes the y-axis is the y-intercept. To find the slope, find two points on the line. Take the increase in the y-coordinate and divide it by the increase in the x-coordinate.

There are 300 students in the middle school, 4 seventh graders are running for class president. Which type of survey below would give biased results?
A) Survey 30 middle school students
B) Survey 30 7th graders
C) Survey 70 middle school students
D) Survey all middle school students
Answer:
B
Step-by-step explanation:
Surveying 30 7th graders would give biased results, because 4 seventh graders are running for class president, meaning that 7th graders would be more likely to vote for their fellow classmates who are running

Answer: 16 units squared
If there is units for the grid, use those as your measurements, but if not, use each box to equal 1.
You can solve this by finding the area of a rectangle bigger than the original shape (straighten out diagonal lines)
Once you do this, count the units (boxes) of the length and width of the rectangle (5 X 4)
You would then multiply the length and width to find the area of the rectangle
5 * 4 = 20
..... But you still need to find the parallelogram so you have to subtract the space you filled in
Since the shape is a parallelogram, you can tell that the area filled in is equal on both sides, and when put together, they form a smaller rectangle
This rectangle would be 1 X 4
1 * 4 = 4
Then you have to subtract the smaller rectangle from the larger rectangle
20 - 4 = 16

Answer:
[tex]\boxed{\sf \ 48 \ }[/tex]
Step-by-step explanation:
Hello,
the sum of all angles of the triangle at the left must be 180
so the last one is 180 - 80 - 60 = 40
and then the angle at the bottom left of the second triangle is 180 - 40 -72 = 180 - 112 = 68
and then the angle that we have to find is 180 - 64 - 68 = 48

A trapezium has two parallel sides of length 12.5 cm and 4.5 cm. It has a height of 7 cm.
What is the area?
Answer:
59.5cm^2
Step-by-step explanation:
Area of a trapezoid is calculated by dividing the sum of parallel sides and that's multiplied by height
(12.5 + 4.5) ÷ 2 × 7 = 59.5cm^2

Is this a fact or opinion? Explain your answer.
If two sets of data have the same mean, they must be the same set of data.
Answer:
opinion
Step-by-step explanation:
2 different sets of data can have the same mean:
for example
4, 5, 6 ---> has a mean of 5
2,6,7 ---> also has a mean of 5
hence it is NOT a fact that if the means are the same, that it must be the same data set
f(x) = x ^ 2 + 6x - 4 in vertex form
Answer:y=(x-6)^2-4
Step-by-step explanation:
Answer:
f(x) = (x + 3)² - 13
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
Given
f(x) = x² + 6x - 4
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² + 6x
f(x) = x² + 2(3)x + 9 - 9 - 4
f(x) = (x + 3)² - 13 ← in vertex form

Answer:
Answer is A
Step-by-step explanation:
(14x^4y^6)/(7x^8y^2)
because everything is one term, you can split into three terms
14/7, x^4 / x^8 , and y^6/y^2
multiplying these three terms will get us the starting term
14/7 = 2
x^4 / x^8
with division of exponents, you subtract the smaller exponent (4), from the big exponent (8), and leave it on the same side (bottom) as the big exponent
1/x^4
same thing with our y's
y^6/y^2
this time, the term stays on the top
y^4
take the simplified terms and multiply them together
(2) * (1/x^4) * (y^4) =
A: (2y^4) / (x^4)
Gracie has 1/2 of a cantaloupe that she wants to divide. How many 's 1/8 of a cantaloupe are there in 1/2 of a cantaloupe?
Answer:
4/8
Step-by-step explanation:
Dividing a whole cantaloupe into eighths will give you 8/8 or 1. When it is cut in half then divided there is one half of 8/8 or there are 4/8 in one half. This is true because 1/2 and 4/8 are equal terms.

What is equivalent to log2(7)
A.7^2
B.2^7
C.7log(2)
D.log(7)/log(2)
E. Log(2)/log(7)
Answer:
D
Step-by-step explanation:
Using the changing base formula, log base 2 raised to 7 can be written as log7/log2
The correct answer is D. log(7) / log(2).
To find the equivalent of log2(7), you can use the change of base formula for logarithms.
The change of base formula states that log base a of b is equal to log base c of b divided by log base c of a.
In this case, we want to find the equivalent of log2(7), so we can use the change of base formula with base 10 as follows:
log2(7) = log(7) / log(2)
Therefore, the correct answer is D. log(7) / log(2).

Answer:
y + 2 = -2(x - 3)^2
Step-by-step explanation:
We can see immediately that the vertex is at (3, -2).
The vertex form of the equation of a parabola is
y - k = a(x - h)^2.
If the parabola opened upward, the equation would be y + 2 = 2(x - 3)^2. But seeing that this particular parabola opens downward, the equation is
y + 2 = -2(x - 3)^2.
Check: Does the point (2, -4) satisfy this equation?
-4 + 2 = -2(2 - 3)^2 becomes -2 = -2(-1)^2, which is true.
