Answer:
Rational Numbers
Step-by-step explanation:
- An integer in its most simplified form cannot be a decimal nor a fraction, meaning -4/3 nor -0.75 would work.
- A whole number is a number that is either positive or negative but cannot be a decimal in simplified form. -4/3 is -1.333.... which is less than one and negative, meaning it cannot be a whole number due to it obviously being a decimal.
- -4/3 is not a natural number as it is both a decimal and negative.
- -4/3 is not irrational because it repeats when in decimal form.
- -4/3 is rational as in decimal form it repeats and to give more information, rational numbers can be both positive and negative numbers. The 3 that repeats in the decimal form of -4/3 works as a rational number due to this.
Therefore, it would apply to the first square.
Thanks!

Answer:
it depends
Step-by-step explanation:
to be honest with you
Length = 13 = (x + 3)
Width = 14 = (x + 4)
x2 + 7x + 12 = area of the rectangle
can be factored into
(x + 3)(x + 4)
Let L = one of the factors (x + 3)
Let W = the other factor (x + 4)
If x = 10 then
(10 + 3) = 13 = L
(10 + 4) = 14 = W
Checking this can be checked a couple of ways
Plug x = 10 into the original equation
x2 + 7x + 12
102 + 7(10) 12 = 100 + 70 + 12 = 182 = Area
Multiplty the factors
L x W = 13 x 14 = 182 = Area

Answer:
a) How many African-Americans would you expect to get promotions?
Since we have been asked to follow the binomial distribution, (B (40,0.2)
To calculate the mean of the BPD = n*p
where n is the number of promotions and p = probability
= 40 x 0.2 = 8
You expect 8 promotions.
b)
The probability that 5 African-Americans = P (X = 5)
P( X = 5 ) = 40 sqr root ( 5 * 0.2^5 * 0.8^35 ) = 0.0854
c) What is the probability that five or fewer African-Americans receive promotions?
P( X <= 5) = P(X=5) + P(X=4) + ... + P(X=1) + P(X=0)
faster way is calculator
binomcdf(40, .2, 5) = 0.1613
