Option B: isosceles
Option D: right
Solution:
Given data:
Three sides of the triangle are 5 cm, 7.1 cm and 5 cm.
If any two sides of a triangle are equal in length, then the triangle is called
an isosceles triangle.
Here, one side = 5 cm and the another side = 5 cm
Therefore the given triangle is isosceles.
If any one of the angle is 90°, then the triangle is right angled triangle.
Here "L" symbol represents the angle is 90°.
Therefore the given triangle is right angled triangle.
Option B and Option D are correct answer.
Hence the triangle is isosceles and right triangle.

Answer:
210
Step-by-step explanation:
we have given significance level α=3% =0.03
level of significance is nothing but the chances of rejecting a null hypothesis by the test when it given that it is correct. it is denoted by α it also defined as the
level of significance =1 - confidence level
now statistically significant test =0.03×7000=210
so the expected value of statistical significant is 210
Answer:
25 students
Step-by-step explanation:
Let t= total students
Take the total number of students and multiply by the percent that are boys to get the number of boys
t * 40% = 10
Change to decimal form
t*.40 = 10
Divide by .4 on each side
.40t /.4 = 10/.4
t =25
There are 25 students
