Answer:
48.56 cm
Step-by-step explanation:
The rectangle: 10+10+8+8
= 36cm
The half circle: 1/2 πd
=1/2x3.14X8
= 12.56
So, the total perimeter will be- 36+12.56
=48.56

Answer:
40.565cm
Step-by-step explanation:
To find a circumference (perimeter) of a cirlce, you need to use the formula C=2πr.
We know the diameter is 8 but we need the radius, the radius we would divide the diameter in half.
8 ÷ 2 = 4
Now that we know the radius is 4, you plug in 4 for r, and then solve
C= 2π4
C= 25.13
The circumference of the whole circle is 25.13 so we would cut it in half to get the half of the circle we need. So 25.13 ÷ 2 = 12.565.
Now that we have the circumference of the half-circle, it a lot easier. Take the 3 other sides and the half-circle and just add the together
8 + 10 + 10 + 12.565 = 40.565

Alpha level was 0.05, the ratio of true to false effects in this field is 0.7 and the power of this study was 0.8. The probability that this effect is real is
Answers
Answer:
"0.9739" is the correct answer.
Step-by-step explanation:
The given values are:
The ratio of true to false effects,
= 0.07
The power of study,
= 0.8
Alpha level,
= 0.05
Now,
The percentage of effects proved as significant will be:
= [tex]0.8\times \ 70 \ percentage[/tex]
= [tex]0.56[/tex]
0r,
= [tex]56[/tex]%
The percentage of false effects will be:
= [tex]0.05\times 30 \ percent[/tex]
= [tex]0.015[/tex]
or,
= [tex]1.5[/tex]%
The total effects will be:
= [tex]56+1.5[/tex]
= [tex]57.5[/tex]%
hence,
The probability that this effect is real will be:
= [tex]\frac{56}{57.5}[/tex]
= [tex]0.9739[/tex]

Determine whether the given figure tessellates the plane.
a. yes
b. no
Please select the best answer from the choices provided
Answers
Answer:
A. Yes
Step-by-step explanation:
I calculated it logically
Yes the given figure with rectangle tessellates the plane.
A rectangle cannot tessellate a plane by itself because it is not a regular polygon with equal angles and sides.
A rectangle can only tessellate the plane if it is combined with other shapes, such as squares or triangles, to form a regular tessellation.
Yes, the given figure tessellates the plane.
Hence, Yes the given figure tessellates the plane.

Simplifying an expression simply means to collect like terms that are having the same variables or constants and combining them, so as to reduce the expression to the lowest possible value.
Simplifying further by opening the bracket, we have;

Answers
Answer: 3rd quadrant
Step-by-step explanation:
This is a question relating to trigonometry.
First quadrant = Angles between 0∘ and 90∘.
Second quadrant = Angles between 90∘ and 180∘
Third quadrant = Angles between 180∘ and 270∘
Fourth quadrant = Angles between 270∘ and 360∘
Therefore, since 250° is between 180° and 270°, it's in the 3rd quadrant.

Answers
Answer: 2200
Step-by-step explanation:
First we will find the area of the triangle, the formula for that is bh/2
(base multiplied by height divided by 2) then we input the numbers into our formula, 30 is the height of the triangle and 40 is the length of the base. So we have to solve 40*30/2 which is 600, then we solve for the square on the bottom which is b*h ( base multiplied by height) so it is 40*40, so we would get 1600, then we add 600 and 1600 together and get 2200.

∠1 = ∠3 = ∠5 = ∠7 = 81°
∠2 = ∠4 = ∠6 = 99°
Step-by-step explanation:
Vertical and corresponding angles are congruent. Angles 1 and 99° are supplementary, so ...
∠1 = 180° -99° = 81°
Then we have ...
∠1 = ∠3 = ∠5 = ∠7 = 81°
∠2 = ∠4 = ∠6 = 99°

A local school has 14 kindergarten teachers. Of these teachers, 4 are Hispanic, 5 are bilingual, and 3 are both Hispanic and bilingual. If a kindergarten teacher is selected at random, what is the probability that teacher is Hispanic or bilingual? P(Hispanic or Bilingual) = Give answer as decimal (not percent) and round to 3 decimal places.
Answers
Answer:
P(Hispanic or Bilingual) = 0.429.
Step-by-step explanation:
This question is solved treating these events as Venn probabilities.
I am going to say that:
Event A: Hispanic
Event B: Bilingual
Out of 14 teachers, 4 are Hispanic, 5 are billingual, and 3 are both:
This means that:
[tex]P(A) = \frac{4}{14}, P(B) = \frac{5}{14}, P(A \cap B) = \frac{3}{14}[/tex]
What is the probability that teacher is Hispanic or bilingual?
This is:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
With the values that the exercise gives us:
[tex]P(A \cup B) = \frac{4}{14} + \frac{5}{14} - \frac{3}{14} = \frac{4 + 5 - 3}{14} = \frac{6}{14} = 0.429[/tex]
So
P(Hispanic or Bilingual) = 0.429.

This is because she started with 54 and ended with 12. You need to keep a in the middle since that’s the amount you spent to end up at 12. Have a good day :)
