How do I solve x≤100

Mathematics
1 answer:
Molodets [167]3 years ago
8 0

Answer:


Step-by-step explanation:

There's really nothing to solve here.  Rather, you should describe what x≤100 represents.

To draw an appropriate graph, draw an x-axis, mark x=100 with a black dot, and then draw an arrow to the left from this dot.  That's it.  "All x less than or equal to 100."

What is the interquartile range of 45,60,40,90,60,50,75,120,90
puteri [66]
IQR = 40

1) Put the numbers in order: 40, 45, 50, 60, 60, 75, 90, 90, 120
2) Find the median: Median is 60 (the 2nd one)
3) Place parentheses around the numbers above and below the median. For easy identification of Q1 and Q3. (40, 45, 50, 60,) 60, (75, 90, 90, 120)
4) Find the Q1 and Q3. Q1 = median of the lower half of the data; Q3 = median of the higher half of the data. Q1 and Q3 have even sets so its median cannot be defined.
5) Had both sets contain odd sets, the median of Q1 is subtracted from the median of Q3 to get the IQR.

We can then use the Alternative definition of IQR.
IQR is the difference between the largest and smallest values in the middle 50% of a set data.

40, 45, 50, 60, 60, 75, 90, 90, 120

Middle 50% is 50, 60, 60, 75, 90; IQR = Largest value - smallest value;

IQR = 90 - 50 = 40

200+200= + 400

=1000m

1km = 1000m

1. Solve *
Salsk061 [2.6K]

Answer:

x = -8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(3x−2)=8(2x+3)

(4)(3x)+(4)(−2)=(8)(2x)+(8)(3)(Distribute)

12x+−8=16x+24

12x−8=16x+24

Step 2: Subtract 16x from both sides.

12x−8−16x=16x+24−16x

−4x−8=24

Step 3: Add 8 to both sides.

−4x−8+8=24+8

−4x=32

Step 4: Divide both sides by -4.

−4x

−4

=

32

−4

x=−8

Answer:

x=−8

the equation of a parabola is 12y=(x-1)^2-48 identify the vertex , focus, and directrix of the parabola.
amm1812

the equation of a vertically opening parabola is

(x - h)² = 4p(y - k)

where (h, k) are the coordinates of the vertex and p is the distance of the focus and directrix from the vertex. If 4p is positive parabola opens up and if 4p is negative parabola opens down

rearrange 12y = (x - 1)² - 48 into this form

(x - 1)² = 12y + 48

(x - 1)² = 12( y + 4) ← in standard form

Vertex = (1, - 4 )

4p = 12 ⇒ p = 3 ⇒ parabola opens upwards

the focus is above the vertex and the directrix is below the vertex in a vertically opening up parabola

Focus = (1, - 4 + 3 ) = (1, - 1)

Directrix has equation y = - 4 - 3 ⇒ y = - 7
