Each hour you work is already $7.00, without overtime (more than 40 hours a week)
So if you work 40h and earn $7.00 a week, 40h*$7.00 = $280
but since you work 50 hours, 10 hours are over time so you earn 1.5*the $7.00 which is $10.50 for those 10 hours
So $10.50*10h = $105
So now you add the 280 you already made plus the $105 in over time.
105+280
The answer is $385
Answer:
£300.
Step-by-step explanation:
He has £900 left after paying rent.
The fraction he spends on bills = 3(4+3+2)
= 3/9
= 1/3.
So he spends 900 * 1/3 = £300 on bills.
The 2 triangles are similar so corresponding sides are in the same ratio
4/5 = 6 +x / 4x- 8
cross multiply;
30 + 5x = 16x - 32
11x = 62x
x = 5.636
AB = 4(5.636) - 8 = 14.545
Answer:
Step-by-step explanation:
a)
y=−1/12x^2+6x+3
y=−1/12(0)^2+6(0)+3
y = 3
b)
y=−1/12x^2+6x+3
y = -1/12 (x^2-72x) + 3
y = =-1/12 (x^2-72x+1296-1296) +3
y = -1/12(x^2 -72x +1296) + 108 + 3
y = -1/12 (x - 36)^2 +111
maximum height of the ball is 111 feets
c)
y = -1/12 (x - 36)^2 +111
0 = -1/12 (x - 36)^2 +111
-111 = -1/12 (x - 36)^2
1332 = (x - 36)^2
36.497 = x - 36
x = 72.497
How far from the child does the ball strike the ground = 72.497 feets
Answer:
99% confidence interval bto estimate the average price customers are willing to pay per phone is between a lower limit of $471.356 and an upper limit of $514.
Step-by-step explanation:
Confidence interval = mean + or - Error margin (E)
mean = $492.678
sd = $26.4871
n = 14
degree of freedom = n - 1 = 14 - 1 = 13
confidence level = 99%
t-value corresponding to 13 degrees of freedom and 99% confidence level is 3.012
E = t×sd/√n = 3.012 × $26.4871/√14 = $21.322
Lower limit = mean - E = $492.678 - $21.322 = $471.356
Upper limit = mean + E = $492.678 + $21.322 = $514
99% confidence interval to estimate the average price customers are willing to pay per phone is between $471.356 and $514.
