Answer:
She must buy 90 tiles for the cost to be the same at both stores
Step-by-step explanation:
Let x be the no. of tiles bought for the cost to be the same at both stores
Margo can purchase tile at a store for $0.89 per tile at shop 1
Cost of x tiles =0.89x
She rent a tile saw for $45.
So, total cost at Store 1 = 0.89x+45
At another store she can borrow the tile saw for free if she buys tiles there for $1.39 per tile.
So, cost of 1 tile = 1.39
Cost of x tiles = 1.39x
ATQ
0.89x+45=1.39x
45=1.39x-0.89x
45=0.5x
90=x
Hence She must buy 90 tiles for the cost to be the same at both stores
Making predictions about your data requires the usage of a hypothesis. They aid data analysts in determining what they want to verify or dispute.
Given,
A senior data analyst requests that a junior data analyst offer two hypotheses for a project involving data analytics.
The rationale for a hypothesis must be explained;
This is,
Hypothesis testing is a sort of statistical reasoning that uses information from a sample to draw conclusions about a population parameter or population probability distribution. The parameter or distribution is initially best guessed.
Here,
A hypothesis seeks to infer something from your data. Data analysts use them to show or refute what they want to prove.
