Answer:
x=0.2, y=6
Step-by-step explanation:
Since y=20x+2, 5x+y=7 => 5x + (20x +2 ) = 7
25x + 2 = 7
25x = 5
x = 0.2
so y = 20x + 2 = 20* 0.2 +2 = 4 + 2 = 6
so the final solution is [tex]\left \{ {{y=6} \atop {x=0.2}} \right.[/tex]
The values of x and y for the given simultaneous equation are;
x = 0.2 and y = 6
We are given 2 simultaneous equations;
5x + y = 7 ---(eq 1)
20x + 2 = y ----(eq 2)
Put 20x + 2 for y in eq 1;
5x + 20x + 2 = 7
25x + 2 = 7
25x = 7 - 2
25x = 5
x = 5/25
x = 0.2
Put 0.2 for x in eq 2 to get;
20(0.2) + 2 = y
4 + 2 = y
y = 6
In conclusion, the values of x and y are x = 0.2 and y = 6.

A manufacturer of game controllers is concerned that their controller may be difficult for left handed users. They set out to find lefties to test. About 13% of the population is left handed. If they select a sample of five customers at random in their stores, what is the probability of each of the following outcomes?
a. The first lefty is the fifth person chosen
b. There are some lefties among the 5 people
c. The first lefty is the second or third person
d. There are exactly 3 lefties in the group
e. There are at least 3 lefties in the group
f. There are no more than 3 lefties in the group
Answer:
a)0.074
b)0.502
c)0.2114
d)0.0166
e)0.01790
f)0.9987
Step-by-step explanation:
Probability of being left handed = 0.13
Probability of being not left handed = 1-0.13 =0.87
They select a sample of five customers at random in their stores
a. The first lefty is the fifth person chosen
Probability that first lefty is the fifth person chosen =[tex]0.87 \times 0.87 \times 0.87 \times 0.87 \times 0.13=0.074[/tex]
b)There are some lefties among the 5 people=[tex]1-P(x=0)=1-0.87^5=0.502[/tex]
c)The first lefty is the second or third person=[tex]0.87 \times 0.13 + 0.87 \times 0.87 \times 0.13 =0.2114[/tex]
d)
[tex]P(x=3)=^5C_3 (0.13)^3 (0.87)^2=\frac{5!}{3!2!}(0.13)^3 (0.87)^2=0.0166[/tex]
e)
[tex]P(x\geq 3)=P(x=3)+P(x=4)+P(x=5)\\P(x\geq 3)=\frac{5!}{3!2!}(0.13)^3 (0.87)^2+\frac{5!}{4!1!}(0.13)^4(0.87)^1+\frac{5!}{5!0!}(0.13)^5 (0.87)^0=0.01790[/tex]
f)
[tex]P(x\leq 3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)[/tex]
[tex]P(x\leq 3)=\frac{5!}{0!5!}(0.13)^0 (0.87)^5+\frac{5!}{4!1!}(0.13)^1(0.87)^4+\frac{5!}{2!3!}(0.13)^2 (0.87)^3+\frac{5!}{2!3!}(0.13)^3 (0.87)^2=0.9987[/tex]

5.) Consider a square with side lengths x.
Write an equation for the perimeter p of the square, then rearrange the equation to make x the subject
Answer:
The perimeter p of the square is:
[tex]p=4x[/tex]
And in terms of x:
[tex]\displaystyle x = \frac{1}{4}p[/tex]
Step-by-step explanation:
Part A)
We are given a square with side lengths x.
Recall that all four sides of a square are equivalent. Therefore, our perimeter is:
[tex]\displaystyle \begin{aligned} p & = x + x + x + x \\ \\ & = 4x\end{aligned}[/tex]
Part B)
To make x the subject of the equation, divide:
[tex]\displaystyle \begin{aligned} p & = 4x \\ \\ x & = \frac{p}{4} \end{aligned}[/tex]
