The length can be 18 and the width can be 2.
18 x 2 = 36
Or the length can be 12 and the width can be 3.
12 x 3 = 36
The length can also be 9 and the width can be 4.
9 x 4 = 36
You can first convert the mixed numbers into fractions and then operate them
if for example you have 3 4/3
to convert it you first multiply the whole by the denominator and then you add the nominator. The denominator is the same.
so 3 4/3=13/3
1) C. 100
a pentagon has 540 degrees
130 + 130 + 90 + 90 + x = 540
440 + x = 540
x = 100
2) C. 169
a hexagon has 720 degrees
151 + 135 + 115 + 75 + 75 + x = 720
551 + x = 720
x =169
155 Liters, multiply the amount of liters within a gallon by the amount shown (42) 3.875 times 42= 155. hope i helped
Answer: n= 14
Step-by-step explanation:
The formula to find the sample size :_
, where p= Prior estimate of population proportion.
z* = Critical value.
E= Margin of error.
Given : Prior estimate of population proportion : p= 0.025
We know that , the critical value for 90% confidence interval :
E= 7.0%=0.070
Then , the required minimum sample size :
i.e. n= 14
Hence, the sample size needed : n= 14
