Answer:
9 3/8 tons
Step-by-step explanation:
The product is ...
(4 3/8 containers)(2 1/7 tons/container) = (35/8)(15/7) tons = 75/8 tons
= 9 3/8 tons . . . of sugar in the shipment
4/5 of 60 = 48. 4/5 = .80 Multiply .80 by 60 =48
Answer:
Step-by-step explanation:
Given that X, the number of square feet per house is N(mean, 137)
Sample size = 19
Sample mean x bar =1350 sq ft
Since population std dev is given,
std error of sample = 
Since sample size is small, t critical value can be used
df = 18
t value for 80% two tailed = 1.333
Margin of error = ±1.333(std error) = ±
Confidence interval = sample mean ±margin of error
= 
Answer:
-12r² + 10xr - 15x + 34r - 24
Step-by-step explanation:
1. Organize it, variables first - as well as adding constants such as 4 and -7
(5x - 6r + 8) (2r - 3)
2. Start by multiplying the 5x by (2r - 3), then -6r, followed by 8
(10xr - 15x) + (-12r^2 + 18r) + (16r - 24)
3. Simplify
10xr - 15x - 12r² + 18r + 16r - 24
4. Order by greatest to smallest factorial
-12r² + 10xr - 15x + 18r + 16r - 24
5. Combine like variables
-12r² + 10xr - 15x + 34r - 24
Answer:
$ 1,131.56
Step-by-step explanation:
1,250x85%=1,062.50
1,062.50x6.5=69.06
1062.50+69.06=1,131.56
