Distributive Property:
The distributive property tells us how to solve expressions in the form of a(b + c).
In this question we have to find two numbers that add up to give 105,
Now replacing 105 by 100 + 5, rewriting the expression as :
distributing 327 over 100 and 5
here a=327, b =100 and c=5
Answer:
You can state the qurstion in an other way
how many integers between 1-100 has 3 in their prime compostion or how many many numbers can be written as 3*a where a is any number
the multiplication table of 3 shows that 3*33=99
which means that highest product below 100 is 3*33
so there are 33 numbers that are divisible by three
Answer:
Step-by-step explanation:
n = 400
Proportion p = 229/400= 0.5725
For 95% confidence interval we use Z value as 1.96
Std error = 0.025
margin of error = 1.96*0.025
Confidence interval 95% = 0.5725±Margin of error
= (0.524, 0.621)
b) When smiled x becomes 277
p = 0.6925
Std error = 0.023
Margin of error= 1.96*0.023
Confidence interval = (0.647, 0.738)
Smiling increases the chances of stopping since mean and conidence interval bounds are showing increasing trend.
Just multiply the number out of the parentheses with the ones inside. So -8 times 9=-72 and 3q times -8=-24q. Now keep the same operation, which is subtraction in this case.So, -72--24q or -72+24q will be the correct answer.
Answer:
500cm2
Step-by-step explanation:
2(9×20)+(7×20)
=360+140=500cm2
