Answer:
x = $42.8
Step-by-step explanation:
Let
Amount of money shalee has in Sept = $x
Shalee October earnings = $48.24
Total money = $x + $48.24
She spent 3/4 of the money on dress
3/4 of (x + 48.24) = $68.28
3/4 * x + 48.24 = 68.28
3/4x + 144.72/4 = 68.28
3/4x + 36.18 = 68.28
3/4x = 68.28 - 36.18
3/4x = 32.10
x = 32.10 ÷ 3/4
= 32.10 × 4/3
= 128.4/3
= 42.8
x = $42.8
Answer: Sample size would be 296.
Step-by-step explanation:
Since we have given that
Standard deviation = 4.8 hours
Margin of error = 0.65 hours
At 98% level of confidence, z = 2.33
So, It becomes,
Hence, sample size would be 296.
Answer:
74.2899408284 meters
Step-by-step explanation:
2.7 : 1.69
