Detailed explanation:
Work completed by Gardner each hour = 1 / 5
Combined work done by Gardner and assistant each hour = 1 / 4
Work done by the helper per hour
= 1 / 4 - 1 / 5
= 1 / 20
Time required for helper to finish the job:
= 20 hours
Answer: La probabilidad que necesitamos es 0.16.
Step-by-step explanation:
Se nos proporciona que
La probabilidad de que el estudiante sea un senior = 0.22
La probabilidad de que el estudiante tenga una licencia de conducir = 0.30
La probabilidad de que el estudiante sea un senior o tenga una licencia de conducir = 0.36
Buscamos la probabilidad de que el estudiante sea un senior y tenga licencia de conducir.
Según la pregunta,
Por lo tanto, la probabilidad que necesitamos es 0.16.
Answer:
14110
Step-by-step explanation:
Let x = number of pages;
μ = 12200; σ = 820
Zscore = (x - μ) / σ
Zscore = (x - 12200) / 820
Zcritical for 99% confidence, with a one-tailed test equals 2.33
Hence, Z at 99% = 2.33
Substituting in for Zscore = 2.33
Zscore = (x - 12200) / 820
2.33 = (x - 12200) / 820
2.33 * 820 = x - 12200
1910.6 = x - 12200
1910.6 + 12200 = x
x = 14110.6
x = 14111
The number of pages to advertise for the cartridge is 14,110
Answer:- 1. True. A compass serves the purpose of drawing circles and arcs in geometric constructions.
2. False. A standard geometric construction necessitates the use of a straightedge, compass, and pencil, among other tools, to accurately draw a geometric figure.
3. True. Geometric constructions are crafted using a compass and straightedge.
4. True. Protractors assist in geometric constructions for measuring angles, while rulers are employed to gauge segment lengths.
