Answer:
first, make a dot on (0,-1)
Then, you draw a line that is -1/2
The way you draw a line explaination:
for every x, you go down and left by half a box.
for example, the next dot is (-1, -1.5)or (-1, -1/2)
and the next point after that is (-2, -1) and so on...
reminder: it goes on forever on both sides!
Answer:
A. n = 5
Step-by-step explanation:
S = n² + n
When S = 30:
n² + n = 30
Subtract 30 from both sides: n² + n - 30 = 0
Factorize: (n - 5)(n + 6) = 0
Therefore n = 5 or -6
As n > 2, then n = 5 only
We can use the number line as a model to help us visualize adding and subtracting of signed integers. Just think of addition and subtraction as directions on the number line. There are also several rules and properties that define how to perform these basic operations.
To add integers having the same sign, keep the same sign and add the absolute value of each number.
To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.
Subtract an integer by adding its opposite.
Answer:
a.0.0078125
b. 0.1640625
c. 0.0078125
d. 0.0078125
Step-by-step explanation:
To solve this question we can use the binomial probability function:
where
- n is the number of trials in this case the number of children
- k is the number of successes, we can think it as the number of boys
- p is the probability that is a boy
- q is the probability that is a girl,
In this case case p=q
Then
(a) 
(b) 
(c)
(d) 
(a), (c) and (d) are equal as a result of equal probability of giving birth to a boy or a girl. (b) is different because it takes into account the different orders that births can occur
