Derek is selecting a sock from his drawer .He chooses a sock at random and then selects a second sock at random .what is the probability that Derek selected a striped sock both times
Answers
Answer: 1/15
Step-by-step explanation:
The number of striped socks is 2 while the number of total socks are 6. If he chooses a striped socks at first, that will be 2/6.
If he chooses it the second time, the probability will be 1/5 since there'll be 5 socks left and 1 striped.
The probability that Derek selected a striped sock both times will be:
= 2/6 × 1/5.
= 2/30
= 1/15

Consider solving 푥2+12푥+5=0by completing the square. What number should be added to both sides of the equation? 푥2+12푥+_____=−5+_____a. -36b. 36c. 16d. -16
Answers
Answer:
B. 36
Step-by-step explanation:
The equation in question is not well written. Let the equation be;
x²+12x+5 = 0
In order to know what number should be added to both sides of the equation, we will take the square of the half of coefficient of x as shown;
Coefficient of x = 12
Half of 12 = 1/2(12) = 6
Square of 6 = 6² = 36
Hence the required number to add to both sides of the equation by completing the square method is 36

he also agrees to pay the loan back over a 10 year period.
how much money in total will he have paid back at the end of 10 years?
Answers
Answer:
the total amount that should be paid back at the end of 10 years is £10,200
Step-by-step explanation:
The total amount that should be paid back at the end of 10 years is shown below:
= Borrowed amount + simple interest
= £6000 + (£6000 × 0.07 × 10)
= £6000 + £4,200
= £10,200
Hence, the total amount that should be paid back at the end of 10 years is £10,200

An ounce of almonds costs $1.40. If Joey buys 2.4 ounces of almonds, how much will he have to pay?
Answers
Answer:
Joey will pay $3.36 for 2.4 ounces of almonds.
Step-by-step explanation:
Given that:
Cost of almonds = $1.40 per ounces
Number of ounces bought by Joey = 2.4 ounces
Cost of 2.4 ounces = Ounces of almond * Cost per ounce of almond
Cost of 2.4 ounces = 2.4 * 1.40
Cost of 2.4 ounces = $3.36
Hence,
Joey will pay $3.36 for 2.4 ounces of almonds.

D. Transitive property
Answers
Answer:
I think B.Reflexive property
The property best describes the congruence statement is
Symmetric property.
What is Congruence?Congruent means same shape and same size. So congruent has to do with comparing two figures, and equivalent means two expressions are equal. So to say two line segments are congruent relates to the measures of the two lines are equal.
We know,
The Symmetric Property states that for all real numbers
if x = y then y=x
and, Transitive Property
The Transitive Property states that for all real numbers
if x = y and y = z then z=x.
and, Reflexive Property
for any x, x = x.
Here, the property used is Symmetric.

Identify the perimeter and area of a square with diagonal length 24in. Give your answer in simplest radical form!!!
242‾√ in; 288 in2
482‾√ in; 288 in2
242‾√ in; 144 in2
482‾√ in; 144 in2
Answers
Answer:
Perimeter: [tex]48\sqrt{2} \: \mathrm{inches}[/tex]
Area: [tex]288\mathrm \: \mathrm{square \: inches}[/tex]
Step-by-step explanation:
If the diagonal of the square is 24 inches, the side length of the square is [tex]12\sqrt{2}[/tex] inches ([tex]2x^2=24^2[/tex]). The perimeter of this square is then [tex]4 \cdot 12\sqrt{2}=\fbox{$48\sqrt{2}\: \mathrm{in}$}[/tex] and the area [tex](12\sqrt{2})^2=\fbox{$288\: \mathrm{in^2}$}[/tex].
The area of the square is 288 in.² and the perimeter is 48√2 in.
Given to us,
Diagonal of the square = 24 in.
We know that for a square,
[tex]\bold{(Diagonal)^2 = 2\times (side)^2}[/tex]
substituting the values,
[tex]{(Diagonal)^2 = 2\times (side)^2}\\24^2 = 2\times (side)^2}\\side = 12\sqrt {2}[/tex]
Also, the area of a square is given by (side)², and, perimeter by (4 x side).
[tex]\bold{Area = (12\sqrt2)^2 = 288 in.^2}[/tex]
[tex]\bold{Perimeter= (4\times 12\sqrt2) = 48\sqrt 2 in.}[/tex]
Hence, the area of the square is 288 in.² and the perimeter is 48√2 in.
