Answer:
Step-by-step explanation:
Total number of kindergarten children in that region that were tested is 160
It is generally believed that nearsightedness affects about 12% of children in a certain region. Therefore,
The expected number of kindergarten children expected to be nearsighted is
12/100 × 160 = 19
Probability of success, p = 0.12
Probability of failure, q = 1 - p = 1 - 0.12 = 0.88
Standard deviation = √npq = √(160 × 0.12 × 0.88) = 4.11
If these two triangles are similar, the ratio of the side length 5 to the side length 8 should be the same as the side length x to the side length 10. In other words, x=6.25. Hope this helped!
Okay, so I'm not doing the diagram bit, but the answer is basically yeah.
Two similar figures do NOT always have equal areas.
However, if you have two of the exact same figure, with the same lengths and everything, they will always, for a fact, have equal areas.
Hope this helps
Is the equal sign meant to be there???
Answer: Yes it is possible to construct a triangle and it will be an isosceles triangle.
Step-by-step explanation:
- The triangle inequality tells that for any triangle, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side.
Given sides of the triangle are 4 inches, 4 inches, and 7 inches.
Here,
So by triangle inequality, a triangle with sides 4 inches, 4 inches, and 7 inches. is possible.
As it has two equal sides as 4 inches , then it must be an isosceles triangle.
