A stemplot titled Minutes to Complete Homework. The values are 0, 5, 10, 10, 15, 15, 18, 20, 25, 26, 32, 35, 37, 38, 40, 43, 45, 45, 45, 48, 49, 51, 53, 53, 53, 53, 55, 60, 60, 60.
How many students took more than 45 minutes to complete their homework?
There are
students who took more than 45 minutes to complete their homework.
Answer:
11 students :)
Step-by-step explanation:
That should be correct if I'm wrong just ignore this.
The number of students who took more than 45 minutes to complete their homework is 11.
What is a stemplot?A stem-and-leaf display, also known as a stem-and-leaf plot, is a technique used to visualize the shape of distribution by displaying quantitative data in a graphical fashion, similar to a histogram.
For the given stemplot the number of students who took more than 45 minutes to complete their homework can be calculated by counting the number of observations that are more than 45.
Therefore, the observations that are more than 45 are 48, 49, 51, 53, 53, 53, 53, 55, 60, 60, and 60.
Hence, the number of students who took more than 45 minutes to complete their homework is 11.

P(-5, 2), Q(4, 5), R(6, – 1), S(-3, -4)
this is a rectangle right and why is it and not rhombus or square?
Answer:
It's a rectangle, but not a rhombus (or square).
Step-by-step explanation:
Let's see the vectors of each next vertex:
[tex]Q - P = (4, 5) - (-5, 2) = (9, 3)\\R - Q = (6, -1) - (4, 5) = (2, -6)\\S - R = (-3, -4) - (6, -1) = (-9, -3)\\P - S = (-5, 2) - (-3, -4) = (-2, 6)\\[/tex]
Firstly, we can notice that it's a parallelogram - because the Q-P side is parallel to the S - R side (if the x:y ratios are the same, the sides are parallel).
A rhombus needs the sides to be of the same length. But the length of a (x, y) vector is [tex]\sqrt{x^2 + y^2}[/tex] and [tex]\sqrt{9^2 + 3^2} > \sqrt{2^2 + (-6)^2}[/tex], we don't even have to compute it exactly. If it's not a rhombus, it's also not a square (every square is a rhombus).
The last thing left is to know if it's a rectangle - for it to be a rectangle, we need to check if the vectors are perpendicular.
We can compute the dot product of the vectors - perpendicular vectors always have a dot product equal to zero. The dot product of two vectors [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is equal to [tex]x_1x_2 + y_1y_2[/tex].
[tex](9, 3) \cdot (2, -6) = 9\cdot 2 + 3\cdot(-6) = 18 - 18 = 0[/tex]
So the sides are perpendicular, and as such - the figure is a rectangle.

Answer:
18.38Explanation:
since this triangle is a right-angled triangle and one its angles equals 45° then it's an isosceles right triangle which means that the side opposite 45° (the side to the left) is equal to 13 too.
so according to pythagoras theorem c = √(a²+b²)
x =√(13²+13²)
x = √(169+169)
x = √338
x ≈ 18.38
note: in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!

Activity 2 Compute for the following: Speed; Distance, Time
1. A car travels 300 kom in 6 hours. What is the average speed of the car in km/h?
Given
Solution
Car travels in 300 kom ( distance) in
6 hours (time)
2. What is the speed of a jet plane that flies 8100 kon in 9 hours? (in km/h)
Given:
Solution
Jet travels 8100 km (distance)in
9 hours (time)
3. A storm is moving toward your house at a speed of 20 kmh.it is now 60 km away from your house. In what time will the storm reach your house?
Given:
Solution:
Storm moving at 20 km/h (speed) at
60 kun (distance)
Speed and direction
In describing the motion of an object, we do not just describe
Answer:
1. 50 km/h
2. 900 km/h
3. 3 hours
Step-by-step explanation:
1. The distance the car travels, Δd = 300 km
For how long it takes the car to travel the 300 km, Δt = 6 hours
Average speed, [tex]\overline v[/tex], is given as follows;
[tex]\overline v = \dfrac{The \ total \ distance }{The \ total \ time \ it \ takes } = \dfrac{\Delta d}{\Delta t}[/tex],
[tex]\therefore \overline v = \dfrac{300 \ km}{6 \ hours} = 50 \ \dfrac{km}{hour}[/tex]
The average speed of the car, [tex]\overline v[/tex] = 50 km/h
2. The distance the jet plane flies, d = 8,100 km
For how long it takes the the jet plane to fly the 8,100 km, t = 9 hours
The speed, v, of the jet plane is given as follows;
[tex]Speed, \ v = \dfrac{Distance}{Time} = \dfrac{d}{t}[/tex]
[tex]v = \dfrac{The\ distance \ the \ jet plane \ flies}{The \ time \ it \ takes \ to \ fly \ thart \ distance } = \dfrac{d}{t }[/tex],
[tex]\therefore v = \dfrac{8,100 \ km}{9 \ hours} = 900 \ \dfrac{km}{hour}[/tex]
The speed of the jet plane, v = 900 km/h
3. The speed of the storm, v = 20 km/h
The distance of the storm from the house, d = 60 km
The time 't' it takes the storm to reach the house is given as follows;
[tex]Speed, \ v = \dfrac{d}{t}[/tex]
Therefore, by cross multiplying and dividing by 'v', we get;
[tex]Time, \ t = \dfrac{d}{v}[/tex]
Plugging in the known values of 'd' and 'v' gives;
[tex]Time, \ t = \dfrac{60 \ km}{20 \ \dfrac{km}{hour} } = 3 \ km \times \dfrac{hour}{km} = 3 \ hours[/tex]
The time it takes the storm to reach the house, t = 3 hours.

HELP !!!! what is the coordinate of the vertex of the following parabola: -8(x-5)=(y+1)^2
a. (-5, 1)
b. (5, -1)
c. (5, 1)
d. (-8, 1)
what is the coordinate of the vertex for the following parabola:
-8 ( x - 5 ) = ( y + 1 ) ² (5, -1)
what is the coordinate of the focus for the following parabola:
-8 ( x - 5 ) = ( y + 1 ) ² (3, -1)
The vertex of the equation of a parabola [tex]- 8 (x - 5) = (y + 1)^2[/tex] by compared with the standard form of the equation of a parabola [tex]x = a (y - k)^2 + h[/tex] is,
⇒ (h, k) = (5, - 1)
Where, [tex](h, k)[/tex] is the vertex of the parabola.
We have to give that,
The equation of a parabola is,
[tex]- 8 (x - 5) = (y + 1)^2[/tex]
The standard form of the equation of a parabola is,
[tex]x = a (y - k)^2 + h[/tex]
Where, [tex](h, k)[/tex] is the vertex of the parabola.
Here, The equation of a parabola is,
[tex]- 8 (x - 5) = (y + 1)^2[/tex]
It can be written as,
[tex](x - 5) = \frac{(y + 1)^2}{-8}[/tex]
Add 5 on both sides,
[tex]x = \frac{(y + 1)^2}{-8} + 5[/tex]
Now, compare with the standard form of the equation of a parabola,
h = 5
k = - 1
Therefore, the vertex of the parabola is, (5, - 1).

Margo wants new carpet and a new wallpaper border for her bedroom. The room is 5.7 yards long and 6 7 8 yards wide. About how many square yards of carpet will she need? About how many yards of wallpaper border will she need?
Answer:
39.19 yards^2
25.15 yards
Step-by-step explanation:
To determine the squares square yards of carpet needed, we have to determine the area of the room
The room is shaped like a rectangle
area of a rectangle = length x breadth
5.7 x 6 7/8
To multiply, convert 6 7/8 to a decimal
to do this, divide 7 by 8. Add the value gotten to 6
5.7 x 6.875 =39.19 yards^2
To determine the yards needed for the border, calculate the perimeter of the room
Perimeter = 2 x (length + breadth)
2 x(5.7 + 6.875) = 25.15 yards
Classify the triangle with the given side lengths: 5, 9, 10

Answer:
[tex]\boxed {\boxed {\sf D. \ x=20}}[/tex]
Step-by-step explanation:
If line m and line r are parallel, the two angles must be congruent, because they are alternate interior angles. Notice how the 2 lines and the transversal form a backwards "Z" and the angles are in the inner corners.
So, if the angles are congruent, we can set them equal to each other.
3x-357x-115[tex]7x-115=3x-35[/tex]
Now, solve for x by isolating the variable. First, move all the constants to one side and the terms with variables to another.
115 is being subtracted and the inverse of subtraction is addition. Add 115 to both sides.
[tex]7x-115+115=3x-35+115\\7x= 3x+(-35+115) \\7x=3x+80[/tex]
3x is being added and the inverse of addition is subtraction. Subtract 3x from both sides.
[tex]7x-3x=3x-3x+80 \\4x=80[/tex]
x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.
[tex]4x/4=80/4\\x=20[/tex]
If the lines are parallel, then x=20 so the angles are congruent.

i need the mean, median, mode, and range
Answer:
the median is 5 the mode is 5 and 2 the mean is 6.25 and the range is 15
Step-by-step explanation:
the mode is 5 and 2 because they both occur the most often
The median is 5 because even though the amount of numbers is even and there is no exact middle the two middle numbers are both 5 and 5+5 equals 10 divided by 2 equals 5
the mean is 6.25 because all numbers added together 75 divided by the amount of numbers 12 equals 6.25
the range is 15 because the range is the diff between the highest and lowest value
