Answer:
[tex]x=27[/tex]
Step-by-step explanation:
Well based on my knowledge, all the angles of a triangle adds up to 180°. ∠D looks pretty much adjacent to ∠A. I suppose that if what I'm thinking about, ∠D and ∠A being adjacent is correct, then this is what you have to do.
∠D = 2x
∠A = ∠D
That means that ∠A is 2x.
Since all angles of a triangle adds up to 180°, you have to add up the angles of ΔABD.
[tex]72+2x+2x=180\\\\72+4x=180[/tex]
Now you subtract 72 from both sides.
[tex]4x=108[/tex]
Then you divide 4 on both sides.
[tex]x=27[/tex]
So, the value of x is 27.

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. Mensa is an international society that has one and only one qualification for membership: a score in the top 2% on an IQ test. a. What IQ score should one have in order to be eligible for Mensa
Answers
Answer:
130.81
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ,
where from the question:
x is the raw score = ?
μ is the population mean = 100
σ is the population standard deviation = 15
We are told in the question that:
Mensa is an international society that has one and only one qualification for membership: a score in the top 2% on an IQ test.
The top 2% means a score in the 98th percentile
The z score of the 98th percentile = 2.054
Hence:
2.054 = x - 100/15
Cross Multiply
2.054 × 15 = x - 100
30.81 = x - 100
x = 30.81 + 100
x = 130.81
The IQ score that one should have in order to be eligible for Mensa is the score of 130.81

Answers
Answer:
17° and 73°
Step-by-step explanation:
For two complementary angles, the sum of angles is equal to 90 degrees.
Let other angle = x
First angle = 5+4x
ATQ,
5+4x+x=90
This is the equation that shows the given problems.
5+5x=90
5x = 85
x = 17°
Other angle = 17
First angle = 5+4x
= 5+4(17)
= 73°
So, the other two angles are 17° and 73° respectively.

Find the y-intercept. 4) 4x + 3y=-3 A) -3 B) 3 C) -5/2 D) -2/5
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]4x + 3y=-3[/tex]
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
Thus,
substituting x = 0 in the equation
[tex]4x + 3y=-3[/tex]
[tex]4(0) + 3y = -3[/tex]
[tex]0+3y = -3[/tex]
[tex]3y = -3[/tex]
divide both sides by 3
[tex]\frac{3y}{3}=\frac{-3}{3}[/tex]
Simplify
[tex]y = -1[/tex]
Therefore, the y-intercept is: -1

Answers
Answer:
Will's share = 48
Olly's share = 32
Step-by-step explanation:
Will's share : Olly's share = 3:2
Will's share = 3x
Olly's share = 2x
3x + 2x = £ 80 {Combine like terms}
5x = 80 {Divide both sides by 5}
x = 80/5
x = 16
Will's share = 3x = 3*16 = 48
Olly's share = 2x = 2*16 = 32

Answers
Answer:
The total weight of the assembly is 7 pounds.
Step-by-step explanation:
The total weight of the assembry is found by the sum of the weights of each components.
We have:
2 wheels, each weighing 2.6 pounds, so 2*2.6 = 5.2 pounds
An axle, which weighs 1.8 pounds, so 5.2+1.8 = 7 pounds
