A small college has 800 students, 10% of which are left-handed. Suppose they take an SRS of 8 students.
Let L = the number of left-handed students in the sample.
Which of the following would find P(L = 2)?
Answer:
Step-by-step explanation:
Probability of finding 2 left handed students out of 8 samples is 0.1488 or 14.88%.
What is Binomial Distribution?Binomial distribution is the distribution of a random variable X for which there are only two possibilities. The probability p for the success and the probability of 1-p for the failure, which consist of n trials.
Given,
Number of students in the college = 800
10% of which are left handed.
Probability of finding left handed student = 10% = 0.1
p = 0.1
q = 1 - 01 = 0.9
Number of samples, n = 8
We have to find P(x = 2)
The formula to calculate binomial distribution is,
P(x) = ⁿCₓ pˣ qⁿ⁻ˣ
P(x = 2) = ⁸C₂(0.1)²(0.9)⁶
= 28 × (0.1)²(0.9)⁶
= 0.14880348
≈ 0.1488
Hence the probability is 0.1488.

2-1
3) 1
4) 8
Answer:
4) 8
Step-by-step explanation:
In the formula y = mx + b, m is the slope and b is the y-intercept
m = 8
b = -1
If m = 8 and m is the slope, then the slope is 8

Answer:
<BED and <DEA, <AEC and <BEC
Step-by-step explanation:
Supplementary angles are two angles whose degree measures add up to 180 degrees. In other words, two angles that form a straight line.
In the given picture that is: <BED and <DEA, together they form line AB.
Another two supplementary angles in the given image are: <AEC and <BEC, they form line AB, from a different perspective.

Answer:
EH = 13 in
Step-by-step explanation:
Angle between a tangent and radius is right, that is
∠ EBH = 90° and so Δ EBH is right
Using Pythagoras' identity in the right triangle
EH² = BE² + BH² = 5² + 12² = 25 + 144 = 169 ( square root both sides )
EH = [tex]\sqrt{169}[/tex] = 13

Answer:
x = 139 degrees
Step-by-step explanation:
first, find what the missing interior angle is:
add the known angles:
90 + 49 = 139
subtract the sum from 180:
180 - 139 = 41
now to solve for x, take 180 and subtract 41:
180 - 41 = 139
x = 139 degrees

Show work to triangles 2 and 3 explaining why they are right triangles
Answer:
Step-by-step explanation:
In order for a triangle to be a right triangle, it has to fit into Pythagorean's Theorem:
[tex]a^2+b^2=c^2[/tex] where c is the hypotenuse.
We need to figure out which is the longest side in each of those triangles and that is the hypotenuse.
In the first set, the sqrt of 443 is 21.04, but that is not the longest side; 24 is. So the Theorem formula for that is:
[tex]\sqrt{443}^2+17^2=24^2[/tex] which gives us
443 + 289 = 576, but 732 does not equal 576, so that one is not right.
In the second set, the sqrt of 725 is the longest side, so that formula is:
[tex]\sqrt{725}^2=14^2+23^2[/tex] which gives us
725 = 196 + 529, and 725 does equal 725, so that one is right.
In the third set, the sqrt of 890 is the longest side, so:
[tex]\sqrt{890}^2=19^2+23^2[/tex], which gives us
890 = 361 + 529, and 890 = 890, so that is a right triangle as well. That's how you know those are right, compared to the first one that is not.

Find the value of x.
Then find the value of y.
Answer:
x = 2°y = 150°Step-by-step explanation:
First, let's find x:-
(15x-2)° = (9x+10)°
15x-2 = 9x+10
6x = 12
x = 2°
Now, let's find y:-
28 + y° = 180°
y = 180-28
y = 150°

1.1 = -8.5 + 6x what is x
Answer: x=1.6
Step-by-step explanation:
1.1=-8.5+6x
+8.5 +8.5 (add 8.5 on each side)
9.9=6x
Divide by 6 on each side to leave the x by itself
x=1.6
Answer:
x= 1.6
Step-by-step explanation:.
1.1=−8.5+6x
Step 1: Simplify both sides of the equation.
1.1=6x−8.5
Step 2: Flip the equation.
6x−8.5=1.1
Step 3: Add 8.5 to both sides.
6x−8.5+8.5=1.1+8.5
6x=9.6
Step 4: Divide both sides by 6.
6x /6 = 9.6/ 6
x=1.6
Answer:
x=1.6

f(x)=18,000(1-0.012)^x ; x represents the number of years since the car started to depreciate and 18,000 = the initial value of the car. What year will you recieve the car when the car value drops below $2,000? Please do a step by step
Answer:
Given
f(x)=18,000(.88)^x
We need to find the value of x when f(x) <2000
2000 = 18000(0.88)^x
0.88^x 2000/18000
0.88^x 1/9
• x = log (1/9) / log (0.88)
• x= 17 (rounded down)

(1)
49sq.cm (ii) 28sq.cm (iii) 16sq.cm (iv) 9sq.em
Answer:
16 cm²
Step-by-step explanation:
The dimension of rectangle = 7cm by 4 cm
The Area of the greatest square that can be cut from the rectangle :
The dimension has to be the Same to form a square :
Hence, the greatest width = 4cm
Therefore, taking the length also as 4cm
Area of square = side length²
Greatest area of square that can be cut = 4² = 16cm²

.On 1st March 2001, the ratio of Freddie’s age to his mother’s age was 1:11
On 1st March 2018, the ratio of Freddie’s age to his mother’s age was 2:5
Write the ratio of Freddie’s age to his mother’s age on 1st March 2030
Answer:
[tex]Ratio =16 : 31[/tex]
Step-by-step explanation:
Let
x = Freddie's age and y = His mother's age
Given
2001:= [tex]x : y = 1 : 11[/tex]
2018:= [tex]x +17: y + 17= 2 : 5[/tex]
Required
The ratio of their age in 2030
[tex]x : y = 1 : 11[/tex]
[tex]x +17: y + 17= 2 : 5[/tex]
Express as fractions
[tex]\frac{x}{y} = \frac{1}{11}[/tex] --- (1)
[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex] -- (2)
In (1), make y the subject
[tex]\frac{x}{y} = \frac{1}{11}[/tex]
[tex]y = 11x[/tex]
Substitute [tex]y = 11x[/tex] in (2)
[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex]
[tex]\frac{x+17}{11x+17} = \frac{2}{5}[/tex]
Cross Multiply
[tex]5(x +17) = 2(11x + 17)[/tex]
[tex]5x +85 = 22x + 34[/tex]
Collect like terms
[tex]22x - 5x = 85 - 34[/tex]
[tex]17x = 51[/tex]
[tex]x =3[/tex]
[tex]y = 11x[/tex]
[tex]y = 11*3[/tex]
[tex]y = 33[/tex]
This means that: In 2001, Freddie was 3 and his mother was 33
In 2030 (29 years after);
Freddie will be: 3 + 29 = 32
His mother will be: 33 + 29 = 62
So, the ratio is:
[tex]Ratio =32 : 62[/tex]
Divide by 2
[tex]Ratio =16 : 31[/tex]
