Answer:
this will be step by step so bear with me
Step-by-step explanation:
first you must plug it into the point slope form
y-y1=m(x-x1)
plug in
y-y1=3(x-2)
distribute the three into the ()
y-4=3x-6
now add 4 to both sides
y=3x-2
now standard form
Ax+By=C
y=3x-2
add 2 to both sides
y+2=3x
subtract y from both sides
2=3x-y
flip around the equation
3x-y=2
It depends on the variable.
If it's something like x < 2, your graph would be a vertical line at x = 2, and everything to left of that line shaded in (because of the less than).
Similarly for y, except it would be a horizontal line with either everything above or below shaded.
You can have other equations like 0<x<4 where everything between x = 0 and x = 4 would be shaded
Answer:
a) 4/25, or 0.16, or 16%
b) 1/5, or 0.2, or 20%
c) The first option - the theoretical and experimental values should become closer the more trials that are performed.
Step-by-step explanation:
a) 4 of Tammy's 25 spins landed on black, so the experimental probability is 4/25, or 0.16, or 16%.
b) The spinner is split into 5 equal sections. Assuming it is fair, the chance of landing in any given section for a single spin is 1/5, or 0.2, or 20%.
c) The theoretical and experimental values should get closers the more trials you do.
For example, consider 1 coin flip vs 100. The theoretical probability of landing on a given side of a coin is 1/2, or 0.5, or 50%. With a single flip, your experimental probability will either be 0% or 100%, both off of the theoretical probability by 50%. After 100 flips however, the experimental and theoretical probabilities will be much closer to each other.
Answer:
the answer is 40.1 cm
Step-by-step explanation:
The adjacent in the triangle is 23cm and the Alpha is 55 degrees, so just insert the formula to find the adjacent which is x .
Tq
The total amount that your friend spent is the sum of the cost for 3 bags of wild bird seed and the bird feeder. By letting x be the cost of each bag of wild bird seed, the total cost for purchasing 3 bags of this is 3x. The equation that may be used to determine x is letter "B. 3x + 18 = 45". Each bag costs $9.
