Let the weights of the two candies be repres. by x and y.
Then x + y = 60, or x = 60 - y
($1.16 / lb) x + ($0.86 / lb) y = ($1.00 / lb) (60 lb) = $60
Then 1.16(60-y) + 0.86y = 60
69.6 - 1.16y + 0.86y = 60 9.6
9.6 = 0.3y Solving for y, y = ------- = 32 lb
0.3
Then x = (60-32) lb = 28 lb
12 × 12 =144+ 6 = 150 I'm pretty sure
Answer: 8 hours
Step-by-step explanation:
<u>Given information</u>
Admission fee = $7.00
Hour rent fee = $1.50
Number of hours = h
Total fee = $19
<u>Set equation according to the given information</u>
Total fee = admission fee + (hours) × (hour rend fee)
<u>Substitute values into the equation</u>
19 = 7 + 1.5h
<u>Subtract 7 on both sides</u>
19 - 7 = 7 + 1.5h - 7
12 = 1.5h
<u>Divide 1.5 on both sides</u>
12 / 1.5 = 1.5h / 1.5

Hope this helps!! :)

Answer:
There is evidence to show that the single-earner couples on average spend more time watching television together
Step-by-step explanation:
Given that a recent study compared the time spent together by single- and dual-earner couples. According to the records kept by the wives during the study, the mean amount of time spent together watching television among the single-earner couples was 61 minutes per day, with a standard deviation of 15.5 minutes. For the dual-earner couples, the mean number of minutes spent watching television was 48.4 minutes, with a standard deviation of 18.1 minutes.

(Right tailed test where x stands for single earner and y for double)
Let us assume sample sizes are 500 each.
Difference -12.600
Standard error 1.066
95% CI -14.6913 to -10.5087
t-statistic -11.823
DF 998
Significance level P < 0.0001
Since p is less than alpha we reject null hypothesis.
