Answer:
The correct option is A,3875 passengers
Step-by-step explanation:
The curve of best fit for the date y=-5x^2+60x+3715
For April which month 4 which means that x is 4
By substituting 4 for x in the equation we can determine y, the number of passengers that arrived on flights at the airport is determined thus.
y=-5*4^2+(60*4)+3715
y=-5*16+240+3715
y=-80+240+3715=3875
The number of passengers that arrived by flights in April, month 4 is 3875
Factor completely 5x2 - 20.

Use the Triangle Inequality Theorem to determine which set of numbers CANNOT form the side lengths of a triangle.
A. 7, 9, 20
B. 6, 14, 17
C. 8, 24, 30
D. 2, 2, 3
E. 12, 22, 32

Step-by-step explanation:
Side lengths do not adhere to the triangle inequality theorem.
How do I find the perimeter for a square and a triangle?
Answer: 24 inches.
Step-by-step explanation:
You can find the perimeter of the polygon by adding the side lengths.
First, find the missing side lengths.
There is a short space between the right side of the square above the triangle. The triangle is 3 inches tall, and the square is 4 inches tall, so that space is 1 inch long.
We can then add the sides to find the perimeter:
4 + 9 + 5 + 1 + 5 = 24 inches long.
Keep in mind that the three inches of the triangle is not included in the sum because it is not on the outside of the polygon. The perimeter only includes the lengths of the exterior sides.
Find the sum of the interior angles
of a polygon with 35 sides.
Find the mean for each data set. Number of Flowers . . . . . . <-----I-----I-----I-----I-----I-----I-----I-----I-----I-----> 10 11 12 13 14 15 16 17 18
Answer:
Well to find the mean of the above
take £ as sigma
therefore,
mean= £fx/£f
This simply means the sum of all the numbers divided by the number of members
therefore,
10 + 11+12+13+14+15+16+17+18= 126
And the number of figure present on the number line are 9, therefore 126 divided by 9
giving you a result of 14
Therefore the mean of the above numbers is 14.
In the basketball game, the Buffalo made a total of 25 shots. Some of the shots are 2- point shots while others are 3- point shots. If the Buffalo scored a total of 57 points, how many were 2-point shots?
Let's let x be the number of 3-point shots made.
Let's let y be the number of 2-point shots made.
So, then we have:
x+y = 25
And we have
3*x + 2*y = 57
So, we can solve this by substitution. Solving the first equation for x:
x=25-y
Now, plugging into the second equation:
3*(25-y) + 2*y = 57
Simplifying:
75-3y+2y = 26
75-57 = y
y=18
So the player made 18 2-point should and 7 3-point shots for a total of 57 points!

a) The angles should sum to 90 degrees as it is a right angle
Thus x = 90 - 24 - 24
x = 42
b)
(i) It would be j as corresponding angles are equal
(ii) p + q + r = 225

Peter's grandma has a trapezoidal garden, as in the picture.
a) What is the length of the fence of that garden?
b) What is the area of the garden?
The word in the top left corner in the picture is not linked to this task.
Length of fence = perimeter of trapezoid
= 12 + 6 + 5 + 5
= 28 meters
Area of garden = [tex]h (\frac{base 1 + base2}{2} )[/tex]
= 4([tex]\frac{12+6}{2}[/tex])
= 4 x 9
= 36 sq. meters
Find the area of the triangle below.
Be sure to include the correct unit in your answer.
65 yd
13 yd
18 yd
Answer:
The area is
[tex]72yd^{2}[/tex]
(square yards)
Step-by-step explanation:
Explanation:
In the given triangle a base 24 y d and the corresponding height 6 y d
is given, so to calculate the area we can use:
A = 1 2× b × h
If we substitute thegiven numbers we get:
A = 1 2 × 24 × 6 = 12 × 6= 72
The units of base and height are the same (yards), so the calculated area is in y d 2 (square yards)
Answer: The area of the given triangle is 72 square yards.

Write three fractions that are equivalent to 1/2
Use a diagram to show how you know you are right.
Answer:2/4 3/6 4/8
Step-by-step explanation:
A)Greg
B)tony
C)Robert
D)John
Answer:
C
Step-by-step explanation:
Let's compare 3/7 and 3/4 first. These two fractions have the same numerator but not the same denominator, so the fraction with the smaller denominator will be larger. Therefore, 3/4 is larger, so we can eliminate A.
4/9 is less than 1/2, and 3/4 is greater than 1/2, so 3/4 is greater than 4/9 and we can eliminate B. The same goes for D.
Therefore, our answer is C) Robert. Hope this helps!
Angle relationships with parallel lines can someone answer please help

m<x and angle measuring 34° are corresponding angles since two lines are parallel with a third line intersecting them.
Question is in the picture
Answer:
y = 2x - 7
Step-by-step explanation:
When x is equal to 0, then the y value is your y-intercept. So, your y-intercept is -7.
Now, pick two points. Let's pick (-1,-9) and (0,-7). We can add these into the slope formula.
[tex]Slope(m)=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{-7-(-9)}{0-(-1)}[/tex]
[tex]m=\frac{2}{1}[/tex]
[tex]m=2[/tex]
Now, we can use the slope and the y-intercept and put them into a slope-intercept equation.
[tex]y=mx+b[/tex]
[tex]y=2x-7[/tex]

1/4* 1/4= 1/16
Answer:
1/16
Step-by-step explanation:
you have 1/4 chance to get 3 in your case if you pick it two times you gotta multiply the chances 1/4*1/4=1/16
Find a monic quartic polynomial f(x) with rational coefficents whose roots include
x=1-sqrt2, and x=2+sqrt5. Give your answer in expanded form.
Answer:
The polynomial hose roots are :
x = 1 - √2 and
x = 2 + √5
Is
x² - (3 + √5 + √2)x + 2 + √5 - 2√2 -√10 = 0
Step-by-step explanation:
The roots of the equation are
x = 1 - √2 and
x = 2 + √5
(x - 1 + √2)(x - 2 - √5) = 0
x²- 2x - x√5 - x + 2 + √5 + x√2 - 2√2 - √10 = 0
x² - (3 + √5 + √2)x + 2 + √5 - 2√2 -√10 = 0
This is the expanded form

They are independent because the cards are always going to stay the same. If each card that was picked and discarded, that would alter the future which would make it dependent. But... since it doesn't change the cards, it is independent.
Answer: independent
Answer:
Independent
Step-by-step explanation:
Since the second selection is made after replacement, the options are exactly the same as the first selection. Therefore the second selection doesn't depend on the first one. Hence, they are independent
If it was without replacement, they would have been dependent
