Answer:0.5, 0.5
Step-by-step explanation:
Given
[tex]P(A\cap B)=0.25[/tex]
Also, A and B are independent events. So, we can write that
[tex]P(A\cap B)=P(A)\times P(B)[/tex]
[tex]0.25=P(A)\times P(B)[/tex]
So, the two most possible value of [tex]P(A)\ \text{and}\ P(B)[/tex] are [tex]0.5\ \text{and}\ 0.5[/tex]

If the second term of a geometric sequence is 4 and the third term is –12, find the
explicit formula.
an= 3•(4/3) n-1
an =-4/3•(-3)n-1
an=-3•(-4/3) n-1
an = 4/3 •(3)n-1
Answer:
[tex]\bold{a_n=-\frac43\cdot(-3)^{n-1}}[/tex]
Step-by-step explanation:
The formula of a geometric sequence: aₙ = a₁ rⁿ⁻¹
[tex]a_2=4\\a_3=-12\\r=\frac{a_{n+1}}{a_{n}}=\frac{-12}{4}=-3[/tex]
[tex]a_1=a_1\div r=4:(-3)=-\frac43\\\\a_n=-\frac43\cdot(-3)^{n-1}[/tex]
The sum of three consecutive even numbers is 108. Write and evaluate an expression in terms of x to determine the smallest of the three numbers. Include parentheses in your expression.
Answer:
[tex]34[/tex]
Step-by-step explanation:
Let the first number be [tex]x[/tex]
The next number be [tex]2[/tex] more than the previous as it is an even number
The second number is [tex]x+2[/tex]
and the last number is [tex]x+4[/tex]
The sum of the numbers is [tex]108[/tex], so the expression will be
[tex]x+(x+2)+(x+4)=108[/tex]
[tex]\Rightarrow 3x+6=108[/tex]
[tex]\Rightarrow x=\dfrac{108-6}{3}[/tex]
[tex]\Rightarrow x=34[/tex]
The smallest of the three numbers is [tex]34[/tex].
HELP Whatisthedifferencebetweenthe4.1%simpleinterestpaidon$2,750for4yearsandthe3.8% interest compounded annually on the same amount over the same period of time? Show your work.
Answer: Simple interest amount larger by $9.00
Step-by-step explanation:
Simple interest of 4.1% on $2,750 for 4 years:
Formula for simple interest is:
= Amount * (1 + rate * no. of periods)
= 2,750 * ( 1 + 4.1% * 4)
= 2,750 * 1.164
= $3,201
Compound interest of 3.8% on $2,750 for 4 years:
= Amount * (1 + rate) ^ no. of periods
= 2,750 * ( 1 + 3.8%)⁴
= $3,192
Difference:
= 3,201 - 3,192
= $9.00

Mr. Rodriguez had his students line up in order from shortest to tallest. Tia was exactly in the middle of all the students. Which measure of center would describe her height?
Answer:
Median
Step-by-step explanation:
The median value of a distribution is obtained by :
FIRSTLY : Arranging the data in order usually ascending order.
Then the 50th percentile of the data is determined , the value which falls in the 50th percentile is the median of the distribution. The 50th percentile is the exact mid value of the distribution.
This describes the exact same way Tia was chosen in the scenario described above. Hence the measure of the center described is the Median.

In a certain candy store, 3 pounds of candy and 2 pounds of mints cost $10.80, and 1 pound of candy and 3 pounds of mints cost $5.35. What is the cost per pound of the candy and the mints?
If m = price of mints and c = price of candy, then which of the following expressions is equal to 5.35?
Answer:
m = 0.75well 1.7 bc 5.35/3=1.7 This is the cost per pound of the mints.
Step-by-step explanation:
From this sentence >> 3 pounds of candy and 2 pounds of mints cost $10.80
you can make-up an equation >> 3c + 2m = 10.80 right?
That's your first equation, 3c + 2m = 10.80 ... (1)
and from this sentence >> 1 pound of candy and 3 pounds of mints cost $5.35
you can make-up an equation >> c + 3m = 5.35 ... (2)
you can use various methods here, like graphing, substitution, comparison, and elimination method.
Let's try using substitution method.
3c + 2m = 10.80 ... (1)
c + 3m = 5.35 ... (2) << here you can come up with c = 5.35 - 3m then substitute it to (1)
3c + 2m = 10.80 ... (1)
3(5.35 - 3m) + 2m = 10.80
16.05 - 9m + 2m = 10.80
-7m = -5.25
m = 0.75 <<This is the price of the mint
to get the price of candy, simply substitute m = 0.75 to (1) or (2) if you want, it depends on you.
Either way, you will have the same answer.
Let's try substituting in (1)
3c + 2m = 10.80 ... (1)
3c + 2(0.75) = 10.80
3c + 1.5 = 10.80
3c = 9.3
c = 3.1 <<this is the price of the candy

If 3x - 2 = -x + 10, then x =
Answer:
3x-2 = -x+10
or, 3x+x=10+2
or, 4x=12
or, x=12/4
So, x=3
Answer: 3
Step-by-step explanation:
Step 1: Add x to both sides.
3x−2+x=−x+10+x
4x−2=10
Step 2: Add 2 to both sides.
4x−2+2=10+2
4x=12
Step 3: Divide both sides by 4.
4x

Step-by-step explanation:
The Cheer Squad is raising money to pay for their trip to the State Finals. They already have $1200 and they are selling really big candy bars for $10 each
If they need at least $3000, how many candy bars do they need to sell? Write an inequality and solve it
Answer:
10c + 1200 ≥ 3000, c≥ 180
Step-by-step explanation:
We know that they need at least $3000; meaning, it may be $3000 or more. This leaves us with eliminating the bottom two choices.
We then look at the first two choices. If we were to subtract from 1200, we would not know the total income amount that has been gained. It would also eventually give us negative numbers. We cannot have a negative amount earned. Instead, we would use the 10c+1200 because this would allow us to visualize that it needs to be greater than or equal to 3000
Find the area of the regular hexagon if the radius of a circle inscribed in the hexagon is 10√3
meters.
Answer:
D. 600√3Step-by-step explanation:
Refer to your previous question:
https://brainly.com/question/22624022Radius of the inscribed circle is the apothem of the hexagon.
Apothem (a) and half of the side (s) make a 30-60-90 right triangle.
The ratio of the legs, as per property of 30-60-90 triangle:
s : a = 1 : √3 ⇒ s : 10√3 = 1 : √3 ⇒ s = 10Half the side is s = 10 units, then side of the hexagon is 20 units.
The area of the hexagon:
A = 1/2Pa, P- perimeter, a- apothem A = 1/2(6*20)*(10√3) = 600√3Correct choice is D

"hypotenuse" of the triangle: if the height is 24 feet and base is 36 feet.
Answer:
43.27
Step-by-step explanation:
(24×24)+(36×36)= 1872
√1872=43.27
Using the Pythagorean theorem:
Hypotenuse = sqrt( 24^2 + 36^2)
Hypotenuse = sqrt(576 + 1296)
Hypotenuse = sqrt(1872)
Hypotenuse = 2sqtt(469) or 43.266
