Answer:
y=x/2+5/2
Step-by-step explanation:
4=1/2(3)+5/2
y=×/2+5/2
Answer:
Pr(≥ 70%) = 2/5 = 0.4
Step-by-step explanation:
This question is incomplete as we can't get an exact answer without the dot plot diagram.
We can tell from the question, we are to determine the probability of having ≥ 70% students that play sports
The dot plot diagram used in solving the question has been attached.
Total number of samples = 20
From the dot plot, 50% of students play sport. That is, 50% have more people playing sport than others.
The chance of getting a sample proportion of 70% or greater= probability of students that like sports ≥ 70%
= (sum of people that like sports ≥ 70%)/(total number of sample)
Pr(≥ 70%) = (4+3+1)/20
Where Pr = probability
Pr(≥ 70%) = 8/20
Pr(≥ 70%) = 2/5 = 0.4
In this problem, I would say 7.16 to the nearest 10th would be 7.20 because 16 is closer to 20 then 10.
Answer:
d = 102 m
Step-by-step explanation:
A cross-country skier moves 36 meters eastward, then 44 meters westward, and finally 22 meters eastward. We need to find the distance covered by the skier. We know that, the distance covered by an object is equal to the sum of its journey. So,
distance = 36 m + 44 m + 22 m
Distance = 102 m
So, the skier's distance covered is 102 m.
4/5 - 1/6 = 24-5 / 30 = 19/30
19/30 * 1/2 = 19/60 cups of sugar. Wonder how he measured that?
