Answer:
100 : 250
Step-by-step explanation:
Sum the parts of the ratio, 2 + 5 = 7 parts
Divide the quantity by 7 to find the value of one part of the ratio.
350 ÷ 7 = 50 ← value of 1 part of the ratio, thus
2 parts = 2 × 50 = 100
5 parts = 5 × 50 = 250
350 = 100 : 250 in the ratio 2 : 5
Suppose the spinner lands on <em>a</em>. There's a 1/3 chance that it'll land on <em>a</em> the second time.
Suppose the spinner lands on <em>b</em>. There's a 1/3 chance that it'll land on <em>b</em> the second time.
Suppose the spinner lands on <em>c</em>. There's a 1/3 chance that it'll land on <em>c</em> the second time.
We've covered all possibilities for the first spin, and they're all equal, so their average is 1/3.
The probability that it'll land on the same letter twice is 33.3%.
the function is decreasing and the y intercept is (0,1)
The answers are as follows:
1. Triangles are often used to build different types of support structures because of its beneficial properties. Triangles is rigid in shape and it has strength. When force is applied to the side of a triangle, it can not shift into another shape, this is because its sides and angles are fixed.
2. The properties of triangle that make it a desirable geometric shape for building support structures is its fixed sides, fixed angles, rigidity and strength. Triangles are the strongest shapes and they are stable. Thus, triangle can be easily fix together to provide strength and stability over a wide area.
3. There are different types of triangles, these include: equilateral triangle, scalene, isosceles, right triangle, obtuse and acute. Of all these triangles, the best triangle is equilateral triangle.
4. Triangle is preferred over other types of polygon because, it is the strongest. The other polygons can be bent into different other forms that are not regular polygon, but a triangle always retains its shape and can not be deformed.
Answer:
75% students read less than 35 pages.
Step-by-step explanation:
The stem and leaf plot is given below
0 | 5 0 5 8
1 | 2 3 5 8 8 9
2 | 2 4 6 7 7 7
3 | 3 5 6
4 | 2 4 6
5 | 7
Count the students in each row.
Row 1 = 4 students
Row 2 = 6 students
Row 3 = 6 students
Row 4 = 3 students
Row 5 = 3 students
Row 6 = 1 student
Total students = 23 students
75% of 23 students = 0.75/100 · 23 = 12.25 students
75% of 23 students ≅ 17 students
From the stem and leaf plot, 17th student read 33 pages while 18th student reads 35 pages.
Which means
75% students read less than or equal to 33 pages.
OR
75% students read less than 35 pages
