Answer:
[0.4979, 0.5479]
Step-by-step explanation:
-We first determine the sample proportion:
-The confidence intervals of a sample proportion is calculated using the formula:
#We substitute for the sample proportion and z value to get the Confidence interval:
Hence, the 90% confidence intervals is [0.4979,0.5479]
Answer:
It is not direct variation.
Step-by-step explanation:
In a direct variation, each y value divided by its corresponding x-value gives the same quotient, which is the constant of variation. Let's try two y-values and their corresponding x-values.
11/7 = 1.571428...
13/8 = 1.625
Since the two quotients above are different, there is no constant of variation, and the relation is not direct variation.
24 + 36
12(2 + 3) (take out common denominators)
12(5) = 60
24 + 36 = 60
True
hope this helps
Step-by-step explanation:2/3 ( x-4) =x+13( [2/3] [x-4] )= x+1 ...........multiply both side by 32(x-4)=x+1 2x-8=x+1 2x-x=1+8X=9 the value of x is 9.
Answer:
If i was to read this out loud, i would say: 5 plus the quantity of 17 minus 8.
Step-by-step explanation:
5 + (17-8)
Parenthesis need to be done first! That is why you need to say 'the quantity of...' You also have to add 5 to it all, and you might as well do it before 'the quantity of...' becuz it comes before it in the numerical expression.
YAY! ! ! YOU GOT IT!!! =)
