I’m not sure but you can use a calculator I saw a fantasy one at Walmart with A SCREEN ON IT!??? it’s $100 but it would probably help ALOT
Answer:
D x>-3
Step-by-step explanation:
3(-x+2) < 15
-3x + 6< 15 (Subtract 6 from both sides)
-3x < 9 (Divide 3 on both sides)
x>-3 (Flip the inequality because the variable was negative)
Answer:

Step-by-step explanation:
We are given the following in the question:
The organizers estimate that the variation in distance flown by the athletes will be σ = 10 meters.
This will be stated by the null hypothesis.

It was claimed that the organizers are underestimating the variation and the variation in distance is greater than 10.
This will be stated by the alternate hypothesis.

The parameter for the given hypothesis is standard deviation,
.
Answer:
Step-by-step explanation:
Points are said to be collinear if they all lie on a line .
Let points L , M, N be collinear i.e they all lie on a line .
Consider the following figure :
Given :
LN = 54 units
LM = 31 units
To find : MN
Solution :
Clearly we can see LM + MN and LN coincides each other and we know that two things which coincide are equal to each other .
Therefore , LM + MN = LN
31 + MN = 54
On transposing 31 to RHS , we get MN = 54-31 = 23 units
{ Transposition is basically a process of taking one number from side to the other with the opposite operation }
