Answer:
The correct answer is
Step-by-step explanation:
Snow cone holders are sold in sleeves of 50.
The cones have a slant height (l) of 5 inches and a radius (r) of 3 inches.
Surface area of each cone holder = π × r × l = π × 15 = 15π square inches.
Surface area of all 50 cones in the sleeve = 15π × 50 = 750π = 2357.143 square inches.
Thus 2357.143 square inches pf paper would be necessary for each sleeve each having 50 cone holders.
2x2=4, 5x6=30
Not sure if they’re one expression, of so it’s (2x2)+(5x6)=34
Answer:
9.72
Step-by-step explanation:
s1 = 10.6383 ; s2 = 5.21289
x1 = 147.583 ; x2 = 136.417
n1 = 12 ; n2 = 12
df1 = n1 - 1 = 12 - 1 = 11
df2 = n2 - 1 = 12 - 1 = 11
The test statistic :
(x1 - x2) / sqrt[(sp²/n1 + sp²/n2)]
Pooled variance = Sp² = (df1*s1² + df2*s2²) ÷ (n1 + n2 - 2)
Sp² = ((11*10.6383) + (11*5.21289)) / 22 = 7.926
Test statistic, T* :
(147.583 - 136.417) / √(7.926 * (1/12 + 1/12))
11.166 / √(7.926 * (1/6)
11.166 / √1.321
11.166 / 1.1493476
T* = 9.7150766
Test statistic = 9.72
