Answer:
A. The distribution should be skewed to the left because the mean is less than the median.
B. Most students scored a C or higher.
Step-by-step explanation:
A. Since mean<median<mode, we have a negative skewness and hence the distribution is skewed to the left.
B. Since the mean score is 71 and the modal score is 81, it is expected that a 'C' should be the lowest grade most students will have.
The answer is 20 days, we can solve this in following way:
Each friend creates 4 bags of dough and after ten days four bags divided into four more bags means:
3 friends x 4 bags = 12 bags and 12 bags x 4 = 48 bags
so in next 10 days, the 48 bags will be further divided into 4, so
48 x 4 = 192 bags
10 days + next 0 days = 20 days
so 20 days is the answer.
Answer:
Análisis del problema
Nos dan como datos el tiempo que se tarda cada uno en pintar la habitación:
Gerardo: 3 horas
Ángel: 6 horas
La velocidad de trabajo podemos definirla como dada por la cantidad de habitaciones que pueden pintar sobre el tiempo: H/t
Gerardo: 1 hab /3h
Ángel: 1 hab / 6h
Sumamos ambas velocidades de trabajo:
Por lo tanto entre los dos pintarían una habitación en dos horas.
to make one dozen, you will have to divide 2 by 1.5, which is 0.75, therefore 0.75x3=2.25
