Answer:
Mercury, then MarsStep-by-step explanation:
Given diameters of planets:
Mercury ⇒ 4.87 × 10³ km = 4 870 kmVenus ⇒ 1.21 × 10⁴ km = 12 100 kmEarth ⇒ 1.28 × 10⁴ km = 12 800 kmMars ⇒ 6.79 × 10³ km = 6 790 kmCompared, we see the smallest value belongs to Mercury
The second smallest planet is Mars

Solve for the value of x.
Answer:
x=4/3
Step-by-step explanation:
9x+8=12x+4
Subtract 8 from both sides;
9x+8-8=12x+4-8
Simplify;
9x=12x-4
Subtract 12x from both sides;
9x-12x=12x-4-12x
Simplify;
-3x=-4
Divide both sides by -3
-3x/-3=-4/-3
Simplify;
x=4/3

Given that r is directly proportional to
y and inversely proportional to Z,
x= 15 when y = 10 and Z= 4, find
the equation connecting x, y and Z.
Given:
x is directly proportional to y and inversely proportional to z.
x= 15 when y = 10 and z= 4.
To find:
The equation that connecting x, y and z.
Solution:
It is given that, x is directly proportional to y and inversely proportional to z.
[tex]x\propto \dfrac{y}{z}[/tex]
[tex]x=\dfrac{ky}{z}[/tex] ...(i)
Where, k is the constant of proportionality.
We have, x= 15 when y = 10 and z= 4.
[tex]15=\dfrac{k(10)}{4}[/tex]
[tex]15\times 4=10k[/tex]
[tex]60=10k[/tex]
Divide both sides by 10.
[tex]\dfrac{60}{10}=k[/tex]
[tex]6=k[/tex]
Putting k=6 in (i), we get
[tex]x=\dfrac{6y}{z}[/tex]
Therefore, the required equation is [tex]x=\dfrac{6y}{z}[/tex].

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.

A rectangle has an area of 170.2m2
One of the sides is 3.7m in length.
Work out the perimeter of the rectangle.
Answer:
here
Area = 170.2 M2
Area of rectangle = l *b
let l= 3.7m
170.2 = 3.7* b
b= 46m
now , perimeter = 2(l+b)
= 2( 3.7 + 46)
= 99.4 m
