A sample of 18 randomly selected women is obtainedand the blood platelet count of each subject is measured. The mean is 253.9 and the standard deviation is 63.6. What is the margin of error (round to the nearest tenth)?
Answer:
Margin of error = E = 40
Step-by-step explanation:
Assuming 99% confidence level
Given that x = 253.9
s.d = 63.6
n = 18
Degrees of freedom = df = n - 1 = 18 - 1 = 17
At 99% confidence level the t is, α = 1 - 99% = 1 - 0.99 = 0.01
α/2 = 0.01 / 2 = 0.005
t α/2,df = t,0.005 = = 2.680 (using student t table)
Margin of error = E = t α/2,df * (s.d/√n)
Margin of error = 2.680*63.6/√18
Margin of error = 2.680*63.6/4.242641
Margin of error = 2.680*14.99066265564303
Margin of error = 40.17
Margin of error = E = 40

A shape is shown on the centimetre grid below.
+
Work out the area of the shape
after it has been enlarged by
scale factor 2
State the units of your answer.
The area of the figure after dilation would be 20 square units.
What is scale factor? How it is used in Dilating coordinates?
Scale factor is used to compare 2 quantities, indicating by how much one quantity is greater than the other. It is denoted by K. Mathematically-
K = a/b.
If a coordinate point (x, y) is dilated by a scale factor of [k], then the coordinate point after dilation will be - (kx, ky).
Given is the 2 - D figure as shown.
Assume the length of each side as 1 units. Then after the dilation by K = 2, each side would be of 2 units. Then, the area of the figure would be -
A = 5(2 x 2) = 5 x 4 = 20 square units
Therefore, the area of the figure after dilation would be 20 square units

In the figure above, point B lies on AD. What is the value of 3x?
A) 18
B) 36
C) 54
D) 72
Answer:
54°
Step-by-step explanation:
We know that a flat line= 180° and ∠ABC is 90° which means 2x+2x+x=90°.
Therefore, 5x=90° so x=18°
18*3=54 so your answer is 54°
3x = 54°
The correct option is (C).
What are angles?An angle is a form of geometrical shape, that is constructed by joining two rays to each other at their end-points. The angle can also be represented by three letters of the shape that define the angle, with the middle letter being where the angle actually is (i.e.its vertex). Angles are generally represented by Greek letters such as θ, α, β, etc.
Given,
In the figure
∠CBA = 90°
and
∠CAB + ∠CBD = 180°
Putting the value by the given figure
90° + x + 2x + 2x = 180°
5x = 180° - 90°
5x = 90°
x = 90° / 5
x = 18°
⇒ 3x = 3 × 18°
⇒ 3x = 54°
Hence, the value of 3x = 54°

Anthony and Michelle have £65.25 between them. Anthony's amount is two thirds of Michelle's amount. How much money does each have?
Answer:
43.50
Step-by-step explanation:
MULTIPLE THE 2 NUMBERS
a. The amount of money that Anthony has is £26.1.
b. The amount of money that Michelle has is £39.15.
Let Anthony's amount be A.Let Michelle's amount be M.Given the following data:
Total amount = £65.25To find the amount of money each of them have:
In this exercise, we are required to translate the word problem into a mathematical (algebraic) expression and solve for the unknown variable (number):
Translating the word problem into an algebraic expression, we have;
Anthony's amount is two thirds of Michelle's amount:
[tex]A = \frac{2M}{3}[/tex] ....equation 1
Anthony and Michelle have £65.25 between them:
[tex]A+M=65.25[/tex] ...equation 2
Substituting eqn 2 into eqn 1, we have:
[tex]\frac{2M}{3} +M=65.25\\\\2M +3M =195.75\\\\5M = 195.75\\\\M= \frac{195.75}{5}[/tex]
M = £39.15
To find the value of A:
[tex]A = \frac{2M}{3}\\\\A = \frac{2\times39.15}{3}\\\\A = \frac{78.3}{3}[/tex]
A = £26.1
