Answer: a. 0.542
b. 0.051
c. 
Step-by-step explanation:
Let p be the population proportion of parents spend too little time with their children because of work commitments
As per given , we have
n= 369
Since the sample proportion is the best estimate for the population proportion.
So , the point estimate of the proportion of the population of working parents who feel they spend too little time with their children because of work commitments = 0.542
z-value for 95% confidence interval : 
Margin of error : 
The margin of error = 0.051
Confidence interval : 
95% confidence interval estimate of the population proportion of working parents who feel they spend too little time with their children because of work commitments :
Answer:
x=27
Step-by-step explanation:
132 + 21 = 153
180 - 153 = 27
Answer:
Step-by-step explanation:
Basically it’s goin to be 50 because it says round to the ten and it’s basically 47
Answer:
x = 30
Step-by-step explanation:
here 50 is hypotenuse as it is opposite of 90 degree.
x and x + 10 are the two other smaller sides of a right angled triangle respectively.
using pythagoras theorem,
a^2 + b^2 = c^2
x^2 + (x + 10)^2 = 50^2
x^2 + x^2 + 20x + 100 = 2500
2x^2 + 20x + 100 = 2500
2x^2 + 20x + 100 - 2500 = 0
2x^2 + 20x - 2400 = 0
2(x^2 + 10x - 1200) = 0
x^2 + 10x - 1200 = 0
x^2 + (40 - 30) - 1200 = 0
x^2 + 40x - 30x - 1200 = 0
x(x + 40) - 30(x + 40x) = 0
(x + 40)(x - 30) = 0
either x + 40 = 0 OR x - 30 = 0
x = 0 - 40
x = -40
x - 30 = 0
x = 30
x = -40,30
since the length and distance is not measured in negative ur answer will be 30

thank u very much . At first i was wrong and giannathecookie i m really sorry
Answer:
114
Step-by-step explanation:
23 × 5 = 100 + 15 = 115
2 + 115 - 3 = 2 + 112 = 114
