Answer:
Integers, Terminating Decimals, Recurring Decimals, Proper and Improper Fractions.
Step-by-step explanation:
The following subset of the real number system can be written in the form , b≠0.
Integers(ℤ): These are positive and negative whole numbers. For example, 5 can be written as
Terminating Decimals: These are fractions that when converted to decimal numbers have an end.
e.g.
Recurring Decimals: These are fractions that when converted to decimal numbers do not have an end.
e.g.
Proper Fractions: These are fractions of the form where a<b. An examples is
Improper Fractions: These are fractions of the form where a>b. An examples is
Answer:
The percentage is
Step-by-step explanation:
From the question we are told that
The random number is
Generally the mean of standard normal distribution is
The standard deviation of a standard normal distribution is
The percentage of the data in a standard normal distribution lies between
is mathematically represented as
The
From the z-table
So
Hence the percentage is
Answer: B
Step-by-step explanation: How do we find the local extrema? Let f be continuous on an open interval (a,b) that contains a critical x-value. 1) If f'(x) > 0 for all x on (a,c) and f'(x)<0 for all x on (c,b), then f(c) is a local maximum value. 2) If f'(x) < 0 for all x on (a,c) and f'(x)>0 for all x on (c,b), then f(c) is a local maximum value.
<span>y = a(x – h)2 + k</span><span>, where </span><span>(h, k)</span><span> is the vertex;
in our case, P(x) = a</span>
Δ/4a ;
a = -36; b = 900; c = -1584;
b/2a = 900/-72 = -12.5;
Δ =
4ac = 810000 - 144*1584 = 581904 => -Δ/4a = 4041;
P(x) = (-36)(x - 12.5)^2 + 4041, where (12.5 , 4041) is the vertex;
Answer: B) 9
Step-by-step explanation:
You are not dumb. You just probably don't know how to solve this.
When you have the same base (3) raised to x exponent, and these bases are dividing each other, you put the same base and subtract exponents.
Another way of looking at this is;
