Answer:
a) Angle XBC = 55° because it's a corresponding angle
AXY = XBC
b) 180° - (55° × 2) = 70°
12 + 4 + 30 + 16 + 18 = 80
80 ÷ 5 = 16
16-12=4
16-4=12
30-16=14
16-16=0
18-16=2
4 + 12 + 14 + 0 + 2= 32
32 ÷ 5 is 6.4
YOUR ANSWER IS 6.4
Answer:
22/24
Step-by-step explanation:
To figure this out, both the numerator and the denominator of the equivalent fraction have to be proportional to 11/12.
To do that, multiply the numerator (11) by 2, (because the denominator of the second fraction is 2 times the denominator of the first fraction).
The second, proportional fraction is 22/24.
Answer:
You would explain what I did in the step by step explanation.
Step-by-step explanation:
There are three types of triangles: equilateral, isosceles, and scalene. An equilateral triangle has all 3 sides congruent, an isosceles has only 2 sides congruent, and a scalene has no sides congruent. So, if the triangle has marked sides congruent, or you have found some sides congruent, then you look at the amount of sides congruent, and then you can find the type of triangle. For example, if you have a triangle called ABC, and AB and BC are congruent but AC is not, then it is Isosceles because 2 sides are congruent. You would explain the 3 triangle definitions to your friend.
We are given with
random samples = 300 batteries
defective samples = 9 batteries
level of significance = 0.1
Using the P-table values and using the given values, we see that the number of defective batteries are really less than 5%
