Answer:
(11, 2 )
Step-by-step explanation:
3y + 2x = 28 → (1)
x = 5y + 1 → (2)
substitute x = 5y + 1 into (1)
3y + 2(5y + 1) = 28 ← distribute parenthesis on left side and simplify
3y + 10y + 2 = 28
13y + 2 = 28 ( subtract 2 from both sides )
13y = 26 ( divide both sides by 13 )
y = 2
substitute y = 2 into (2)
x = 5(2) + 1 = 10 + 1 = 11
solution is (11, 2 )
what is the amplitude and period of f(t) = sin2t
The equation [tex]f(t) = \sin(2t)[/tex] is an illustration of a sine function
The amplitude of the function is 1The period of the function is [tex]\pi[/tex]How to determine the amplitude?The equation of the sine function is given as:
[tex]f(t) = \sin(2t)[/tex]
A sine function is represented as:
[tex]f(t) = A\sin(B(t + C)) + D[/tex]
Where
A represents the amplitude
By comparison;
A = 1
Hence, the amplitude of the function is 1
How to determine the period?In (a), we have:
[tex]f(t) = A\sin(B(t + C)) + D[/tex]
Where the period is:
[tex]T = \frac {2\pi}B[/tex]
By comparison;
B = 2
So, we have:
[tex]T = \frac {2\pi}2[/tex]
[tex]T = \pi[/tex]
Hence, the period of the function is [tex]\pi[/tex]

A cylinder has a height of 23m and a volume of 18488m^3 what is the radius of the cylinder. Round your answer to the nearest whole number
Answer:
Radius=16m
Step-by-step explanation:
It is given that A cylinder has a height of 23 m and a volume of 18,488 m³. then, the volume of the cylinder is given as:
Substituting the given values, we get
≈
Thus, the radius of the cylinder will be 16m.
Answer:
Radius = 16m
Step-by-step explanation:
It is given that A cylinder has a height of 23 m and a volume of 18,488 m³. then, the volume of the cylinder is given as:
[tex]v=\pi r^{2} h[/tex]Substituting the given values, we get
[tex]18488=3.14(r^{2} )(23)[/tex]
[tex]18488=72.22(r^{2} )[/tex]
[tex]r^{2} =255.99[/tex]
[tex]r=\sqrt{255.99}[/tex]
[tex]r=15.99[/tex]
[tex]r=16m[/tex]
Thus, the radius of the cylinder will be 16m.

It is known that 10% of the 9-year old children in a town have three siblings. Fifteen 9-year old children are selected at random. Find the probability that more than 3 of these selected children have three siblings (round off to second decimal place).
Using the binomial distribution, it is found that there is a 0.0555 = 5.55% probability that more than 3 of these selected children have three siblings.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, for the parameters, we consider that:
10% of the 9-year old children in a town have three siblings, hence p = 0.1.Fifteen 9-year old children are selected at random, hence n = 15.The probability that more than 3 of these selected children have three siblings is given by:
[tex]P(X > 3) = 1 - P(X \leq 3)[/tex]
In which:
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]
Then:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{15,0}.(0.1)^{0}.(0.9)^{15} = 0.2059[/tex]
[tex]P(X = 1) = C_{15,1}.(0.1)^{1}.(0.9)^{14} = 0.3432[/tex]
[tex]P(X = 2) = C_{15,2}.(0.1)^{2}.(0.9)^{13} = 0.2669[/tex]
[tex]P(X = 3) = C_{15,3}.(0.1)^{3}.(0.9)^{12} = 0.1285[/tex]
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.2059 + 0.3432 + 0.2669 + 0.1285 = 0.9445[/tex]
P(X > 3) = 1 - 0.9445 = 0.0555
0.0555 = 5.55% probability that more than 3 of these selected children have three siblings.
