Answer:
Use Desmos for the graphs, symbolab for the inequalities answers.
Step-by-step explanation:
If P(A) = 0.25, P(B) = 0.60 and P(A and B) = 0.15, are the event A and B independent? Explain/show work.
Answer:
event A and B are independent because P(A and B) = P(A) x P(B) = 0.15
Step-by-step explanation:
When two events are independent, the probability of both occurring is the product of their separate probabilities, as expressed below;
P(A and B) = P(A) x P(B)
Given;
P(A) = 0.25
P(B) = 0.60
P(A and B) = 0.15
Now, let's check if P(A and B) will be equal to P(A) x P(B)
P(A) x P(B) = 0.25 x 0.60 = 0.15
P(A and B) = P(A) x P(B), thus event A and B are independent.
what is the inequality
Answer:
An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b.

Use the given circle. Find the length s to the nearest tenth.
a) 10.5 in
b) 5.2 in
c) 3.3 in
d) 20.9 in
Answer: its A
Step-by-step explanation:
Any smooth curve connecting two points is called an arc. The length of arc s to the nearest tenth is 10.5 in.
What is the Length of an Arc?Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,
[tex]\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]
where θ is the angle, which arc creates at the center of the circle in degree.
The length of the given arc s, with an angle made at the center equal to (2/3)π and radius of 5 inches can be represented as,
[tex]\text{Length of Arc} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]
[tex]\text{Length of Arc s} = 2\pi \times (5)\times \dfrac{\frac23\pi}{2\pi}[/tex]
[tex]=10.472\approx 10.5\rm\ in[/tex]
Thus, the length of arc s to the nearest tenth is 10.5 in.

Answer:
0.375 in fraction is 38.
4/16 + 2/16 = 0.375
Step-by-step explanation:
mike had a balance of $175 in his bank account at the start of the week.He withdrew $65.00 on Monday, $43.25 on Wednesday, and $56.45 on Thursday.On Friday he deposited $165.30.
1.At the end of the week, does Mike have more or less money in his savings account than he had at the beginning of the week?
2.How much more or less?
3.Show all of your work to support your answers.
Answer:
1. Mike has more money in his savings account than he had at the beginning of he week
2. $0.6 more
3. Current Balance is $175 + $165.30 - $164.7 = $175.6
Step-by-step explanation:
The question is of the format of a word problem, hence we have;
Initial balance in Mike's bank account = $175
Withdrawal on Monday = $65.00
Withdrawal on Wednesday = $43.25
Withdrawal on Thursday = $56.45
Deposit on Friday = $165.30
Total withdrawal = $164.7
Therefore we have;
Current Balance = Initial balance + total deposit - total withdrawal
∴ Current Balance = $175 + $165.30 - $164.7 = $175.6
1. Therefore, based on the above calculations, Mike has more money in his savings account than he had at the beginning of he week
2. Mike has $0.6 more.
3. Current Balance = Initial balance + total deposit - total withdrawal
∴ Current Balance = $175 + $165.30 - $164.7 = $175.6.

Bruce and Krista are going to buy a new furniture set for their living room. They want to buy a couch, a coffee table, and a recliner. They have narrowed it down so that they are choosing between 4 couches, 5 coffee tables, and 9 recliners. How many different furniture combinations are possible?
Answer:
There are 180 possible combinations for the furniture.
Step-by-step explanation:
4*5*9=180
Answer
180 combinations
Step-by-step explanation:
To figure out the number of combinations, we multiply 4*5*9. 4*5 equals 20 and 20*9 equals 180.
consider the following three equations:
linear: y=20x+300
Quadratic: y=5x^2
Exponential: y=10(1.4)^x
use the equations to answer the following questions. Support your answers with work.
1. At an x-value of 11, which equation has the largest y-value?
2. what is the smallest integer value of x for which the value of the exponential equation is greater than the values of both the linear and quadratic functions?
Answer:
1.
y = 20(11) + 300 = 520
y = 5(11)(11) = 605
y = 10(1.4)^11 = 404.96
hence the quadratic formula - y = 5x^2 has the largest y-value
2.
y = 20 (14) + 300 = 580
y = 5 (14) (14) = 980
y = 10(1.4)^ 14 = 1111.20 > this is greater than both equations above
14 is the smallest value of x for which the value of the exponential equation is greater than the values of both the linear and quadratic functions
Step-by-step explanation:
Answer:
1. Quadratic
2. x = 14
Step-by-step explanation:
1. At x = 11
linear: y=20(11) + 300 = 520
Quadratic: y=5× 11² = 605
Exponential: y=10(1.4)¹¹ = 404.956517
2. 10(1.4^x) > 20x + 300
1.4^x > 2x + 30
1.4^x - 2x - 30 > 0
Using trial method:
x > 11
10(1.4^x) > 5x²
1.4^x - 0.5x² > 0
Using trail method:
x > 13
The smallest positive integer which satisfies both inequalities is 14

Find the surface area of the figure. Round the the nearest hundredth.
Answer:
Step-by-step explanation:
surface area of cylinder=2πrh
SA=1/2×2×π×3×25+2 ×(1/2×π×3²)=75π+9π=84π≈84×3.14≈263.76 cm²
if lowerside is also counted then area of lower side=25×6=150
total surface area=263.76+150=413.76 cm²
if we take π=22/7
84 π=84×22/7=12×22=264 cm²
if base is also counted then area=264+150=414 cm²
Pythagorean Theorem: How many yards will the players have to run?
Answer:
≈ 125.3
Step-by-step explanation:
If we're using the Pythagorean Theorem to solve this, then the formula is:
[tex]a^{2}+ b^{2} =c^{2}[/tex]
So basically, by using this formula, you're finding the length that the soccer players will run diagonally. Plug in the numbers:
[tex]110^2 + 60^2 = c^2[/tex]
12100 + 3600 = [tex]c^2[/tex]
15700 = [tex]c^2[/tex]
Take the square root:
15700 = [tex]c^2[/tex]
[tex]\sqrt{15700} = \sqrt{c^2}[/tex]
125.3 ≈ c

There are 12 students in a class: 7 boys and 5 girls. If the teacher picks a group of 5 at random, what is the probability that everyone in the group is a boy?
Answer:
0.027Step-by-step explanation:
The number of groups of 5 boys that we can have from 7 boys is 7C5 = 21
The number of groups of 5 boys that we can have from 12 students is
12C5 = 792
then the probability = 21/792 = 0.026515151515
by the way you can calculate 12C5 and 7C5 using a calculator.

How much will the guitar be worth in 10 years?
Answer:
$44487
Step-by-step explanation:
If you plug in 10 for t, you are left with the following equation:
[tex]V=12000(1.14)^{10}=12000\cdot 3.7072\approx 44487[/tex]. Hope this helps!
Answer: $44,487
Step-by-step explanation:
To solve this, substitute t (the variable for time in the equation) with 10 to represent the value of the guitar after 10 years.
[tex]V = 12000(1.14)^{10}\\V = 12000*3.7072\\\\V = 44487[/tex]
The guitar will be worth $44,487 in 10 years.
