Freshly frozen yogurt is the popular place in town. Saturday is their busiest night. The ratio of number of cones to the number
1 answer:
Answer:
On Saturday night it had sold 35 numbers of cups.
Step-by-step explanation:
On the Saturday night the ratio of the number of cones to the number of cups sold is 6 : 5 in Freshly frozen yogurt however on Sunday night the ratio of the number of cones to the number of cups is 4 : 1.
Now, if the Freshly frozen yogurt sold 42 cones on Saturday night then in the ratio of 6 : 5, it sold cups times the number of cones.
Therefore, on Saturday night it had sold numbers of cups. (Answer)

Answer:
The probability that the maximum speed is at most 49 km/h is 0.8340.
Step-by-step explanation:
Let the random variable<em> </em><em>X</em> be defined as the maximum speed of a moped.
The random variable <em>X</em> is Normally distributed with mean, <em>μ</em> = 46.8 km/h and standard deviation, <em>σ</em> = 1.75 km/h.
To compute the probability of a Normally distributed random variable we first need to convert the raw score of the random variable to a standardized or <em>z</em>-score.
The formula to convert <em>X</em> into <em>z</em>-score is:
Compute the probability that the maximum speed is at most 49 km/h as follows:
Apply continuity correction:
P (X ≤ 49) = P (X < 49 - 0.50)
= P (X < 48.50)
*Use a <em>z</em>-table for the probability.
Thus, the probability that the maximum speed is at most 49 km/h is 0.8340.
