<h3>
Answer:</h3>
3) likely
4) 1/2; equally likely
<h3>
Step-by-step explanation:</h3>
3) You are being asked to translate a numerical value to a subjective statement. There are no hard-and-fast rules for this. Generally, the meanings of the terms you're asked to choose from are ...
- impossible: probability is zero. The outcome cannot occur.
- unlikely: chances are less than even; often, "unlikely" means a probability of 10%, 5%, 1% or lower, depending on the context.
- equally likely: probability is near 50%
- likely: more likely than not. Again, this depends on the context.
- certain: probability is 1. There is no chance the outcome will not occur.
An 80% probability is greater than 50%, so might reasonably be called "likely."
___
4) a. Four of the eight numbers are even, so the probability of obtaining an even number at random is 4/8 = 1/2.
b. A probability of 50% might reasonably be called "equally likely", as the probability the event will occur is equal to the probability it won't.
Answer:
f(x)=(2x-7)^7(x+3)^4
When y=0, (2x-7)^7=0 and x=3.5 OR
(x+3)^4=0, and x=-3
Look at x=h or f(2)
That is 96-56-44+2 and it is not equal to 0. (x-2) is not a factor.
x^3-5x^2+6x-30
after trying 1,2, and 3, I tried 5
5/1===-5===6===-30
==1===0====6====30
(x^2-6) with no remainder
the factors are (x-5)(x^2+6)
the zeroes are 5, +/- i sqrt (6). Only one real 0.
hope this helps let me know in the comments if i'm wrong
A triangle is a three-sided polygon. The sum of angles in a triangle is 180 degrees.
<em><u>Types of triangles </u></em>
- An equilateral triangle : the three sides are equal in length.
- An isosceles triangle : two sides are equal in length
- A right angled triangle : an angle measures 90 degrees
The perimeter of a triangle is (8t -7 + u) centimeters
The perimeter of a triangle is the sum of the three lengths of the triangle
2t +2 + 6t - 7 + u -2
Combine similar terms
(2t + 6t) + (2 - 7 - 2) + u
Add combined similar terms
8t -7 + u

Answer:
y = - 4
Step-by-step explanation:
x = - 2
3x - 2y = 2
substitute x = - 2 into 3x - 2y = 2
3(- 2) - 2y = 2 ← step 1
- 6 - 2y = 2 ( add 6 to both sides ) ← step 2
- 2y = 8 ( divide both sides by - 2 )
y = - 4
