Answer: 3 Y=3
Step-by-step explanation:
Y×3=9
3×3=9
You can also check this by rearranging it and dividing 9 by 3.
9÷3=3.
This works for any similar problem.
Example:
Y×4=12 Y=? Y=3
Rearrange it and divide 12 by 4.
12÷4=Y
12÷4=3
So Y×4=12 because 3×4=12
Hope this helps!
Answer:
c). Two tailed test
Step-by-step explanation:
The given hypothesis are
Null hypothesis: H0:μ= 1.7
Alternative hypothesis: H1:μ≠ 1.7
The alternative hypothesis demonstrates that mean number of children are not 1.7 in 2000. This means that mean number of children can be greater than 1.7 or mean number of children can be less than 1.7. Thus, the given alternative hypothesis indicates the two tailed test.
A) Ang 1 + Ang 2 = 90
B) Ang 1 = Ang 2 + 20
B) Ang 1 -Ang 2 = 20 then adding this to equation A produces
2 Ang1= 110
Ang 1 = 55 degrees
Ang 2 =35 degrees
Answer:
Domain= x∉Real numbers
Step-by-step explanation:
F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4
