(40+x)/2=60

40 +x = 120

x = 80


check :

40+80 = 120

120/2 = 60

 so his second round needs to be 80 mph

Using this distribution, find the probability
kaheart [24]

Answer:

P = 0.3

Step-by-step explanation:

Here, we are to use the probability distribution in the table to calculate the probability that a children has 4 or more shoes in his or her closet

When we say 4 or more, what we mean by this is that the teenager has 4 shoes or 5 shoes

In probability expressions, when we use the term ‘or’ we are simply talking about adding the terms involved

So what we can do here is to add the probability that the teenager has 4 shoes to the probability that the teenager has five shoes

From the table that would be; 0.1 + 0.2 = 0.3

A group of individuals were surveyed about their plans for vacation. There were 21 individuals who said they were going to the d
Alexeev081 [22]

Answer:

140 individuals were surveyed

42 people are planning on going to the mountains

Step-by-step explanation:

The question is missing the information regarding the percentage of people who said that they were going to each of the possible destinations. After a quick google search I've found that, in the original question, 32% of individuals were going to the beach, 15% to the desert, 23% to major cities, and 30% to the mountains.

If 21 people said they were going to the desert, and that corresponds to 15% of the total number of people surveyed, the number of people surveyed is:

21=n*0.15\\n=140\ individuals

140 individuals were surveyed

Since 30% responded "the mountains", the number of people planning on going to the mountains is:

m = 140*0.30\\m=42\ people

42 people are planning on going to the mountains

How would I solve this? Because I don't understand it at all.
Mandarinka [93]

Answer:

v= s/t = sqrt(360^2+480^2) x 0.3048/0.5 = 365.76(m/s)

Step-by-step explanation:

s =sqrt(360^2+480^2)

s-ft-to-m = s*0.3048

t = 0.5
