Answer:
63
Step-by-step explanation:
Total groups: 21
number of students in each group: 3
total = 21 *3 =63
12 boys and 27 girls
1) Add 4 to 9. 13
2) 39 divided by 13 is 3
3)Multiple 3 to 4 boys and 9 girls. 3x4 is 12 boys, 3x9 is 27 girls
Hope this helps!
Answer:
±6
Step-by-step explanation:
Given the mathematical expression;
√36 < √42 < √49
But, √36 = 6 * 6 = 6²
√49 = 7 * 7 = 7²
Simplifying further, we would substitute the new values respectively;
±[6] < √42 < ±[7]
Therefore, evaluating √36 is equal to ±6.
5/6 is not the definite ratio, when you take a larger sample size it could be off by a bit like 499/600 or 501/600
Answer:
The slope intercept form would be y = 3x - 9
Step-by-step explanation:
To find this slone in slope intercept form, all we need to do is solve for y.
6x - 2y = 18 ---> Subtract 6x from both sides
-2y = -6x + 18 ----> Divide both sides by -2
y = 3x - 9
