Total children = 6
1) Probability of 4 girls =4/6=0.66
Probability of at least 4 girls >_ 0.66
That is greater or equal to 0.66
2) probability of 5 girls = 5/ total children
=5/6=0.83
Probability of at most 5 girls <_ 0.83
That is less than equal to 0.83
A real number is any number that is rational, including integers and natural numbers. A rational number is any number that can be written as a ratio or isn't a square root of a number. An integer is any whole number (not including fractions) that exists, negative or positive. A whole number is the same as an integer except it only includes positive numbers.
Since a set of whole numbers wouldn't be able to include any negative numbers, your answer would be your fourth option.
Hope this helped you out! :-)
Answer:
b. -x + y = 0
Step-by-step explanation:
<u />
<u>Direct variation</u>:
Direct variation means "y varies directly as x”:

where k is the (non-zero) constant of variation.
To determine which of the given equations represents a direct variation, isolate y for each and compare with the <u>direct variation equation</u>.
<u>Equation a</u>

This is not a direct variation equation as there is an addition of -2.
<u>Equation b</u>


This is a direct variation equation where the constant of variation is 1.
<u>Equation c</u>


This is not a direct variation equation as y is <u>inversely proportional</u> to x.
<u>Equation d</u>

This equation does not include the variable x, and so is therefore not a direct variation equation.
Rebecca was 2 at first, but 2 years later she is 4. Leslie was 10 at first, but 2 years later she is 12. 12 is 3 times greater than 4.
