Answer:
75 is between 64 and 81.
Step-by-step explanation:
The number 75 falls between 64 and 81, which are both perfect squares.
To find out whether a number is a perfect square, we can take the square root of said number. If the answer is a whole number, then the number is a perfect square.
The square root of 64 is 8 and the square root of 81 is 9, so they are both perfect squares. We know that 75 is between the numbers 64 and 81, therefore our answer is correct.
Hope this helps!

When is at a significance level of 0.0001, the concentration of lead is above in water from Minnesota.
Step-by-step explanation:
The Significance level is the calculation or estimation of the strength of proof that must be seen in a sample, before the hypothesis will be rejected and concluded that the result is statistically true or correct.
In this case, when a data is calculated to be significant at 0.0001 from a recent duty, what the significance level implies in this case is that, at a level of 0.001, the concentration of lead is above or higher in water from Minnesota.
The expression is not factorable with rational numbers
Answer:
The probability that she chooses 3 spades and 2 cards that are not spades is
0.08154
Step-by-step explanation:
52 deck cards have 13 spades , 13 clubs , 13 diamond, 13 hearts
spades = 13
Non spades = 39
Selecting 3 spades = 13C3 (Using combination)
selecting 2 spades = 39C2
in total 5 cards are drawn = 52C5
Probability of drawing 5 cards (3spades+2 non spades)
=
= 0.08154
