Answer: 3 lessons
Step-by-step explanation:
Matt starts swimming lessons on Day 5.
He then goes to swimming lessons every 10 days. The dates he went on lessons are therefore:
First lesson = Day 5
Second lesson = Day 5 + 10 days = Day 15
Third lesson = Day 15 + 10 days = Day 25
Fourth lesson = Day 25 + 10 days= Day 35
<em>He therefore only went for 3 lessons because the 4th lesson was after Day 30. </em>
Answer:
find 2 then from 2 and 3 find about 2/3 of the way from 2-3 and plot it there
Step-by-step explanation:
Answer:
0.8
Step-by-step explanation:
The question here says that In a class of 30 students, 18 are men, 6 are earning a B, and no men are earning a B. If a student is randomly selected from the class, find the probability that the student is a man or earning a B.
Since the question says that 18 out of 30 students are men,6 out of the remaining people earn a "B" and non of the 18 men earn a "B".
The probability of picking a man or a person that earns a "B" is
18/30 (since there are 18 men out of the 30 students)
And 6/30(since there are 6 people that earn a "b")
The probability of picking a man or a "b" earner is
18/30 + 6/30
= 24/30 or 0.8
Answer:
![x=7,\\y=4\sqrt{2}](https://tex.z-dn.net/?f=x%3D7%2C%5C%5Cy%3D4%5Csqrt%7B2%7D)
Step-by-step explanation:
Draw an auxiliary line in the trapezoid forming a triangle and a rectangle. The dimensions of the rectangle are 3 x 4, so the length of the auxiliary line must be 4.
The auxiliary line also creates a 45-45-90 triangle. The auxiliary line itself makes up one leg of the triangle, and since we know it is 4, we can use the Pythagorean Theorem to find y:
![4^2+4^2=y^2,\\y^2=32,\\y=\sqrt{32}=\boxed{4\sqrt{2}}](https://tex.z-dn.net/?f=4%5E2%2B4%5E2%3Dy%5E2%2C%5C%5Cy%5E2%3D32%2C%5C%5Cy%3D%5Csqrt%7B32%7D%3D%5Cboxed%7B4%5Csqrt%7B2%7D%7D)
The length of x can be found by adding the bottom leg of the 45-45-90 triangle and the bottom dimension of the rectangle:
![x=4+3=\boxed{7}](https://tex.z-dn.net/?f=x%3D4%2B3%3D%5Cboxed%7B7%7D)
