First solve the inequality:
(2/3)x +3< -2x-7
(8/3)x< -10
x< -30/8
x<-15/4 or x< -3.75
now look for the answers which satisfy this, and the answer will be D
Answer:
We need a sample size of 564.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
The margin of error is:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
Based upon a 95% confidence interval with a desired margin of error of .04, determine a sample size for restaurants that earn less than $50,000 last year.
We need a sample size of n
n is found when 
So
Rounding up
We need a sample size of 564.
Answer:
6/7
Step-by-step explanation:
The constant rate of change is also know as the slope of the expression
Given
24x-28y=14
Write in standard form y = mx+c
m is the slope
24x-28y=14
-28y = -24x + 14
y = -24x/-28 + 14/-28
y = 6/7 x - 1/2
Compare
mx = 6/7 x
m = 6/7
Hence the constant rate of change is 6/7
9.8(k+9)−5.7
Distribute:
=(9.8)(k)+(9.8)(9)+−5.7
=9.8k+88.2+−5.7
Combine Like Terms:
=9.8k+88.2+−5.7
=(9.8k)+(88.2+−5.7)
=9.8k+82.5
Answer:
=9.8k+82.5
Answer:
5:8
Step-by-step explanation:
You have to combine the yellow and blue then put the blue amount in front.
