Answer:
[tex]\frac{111}{190}[/tex]
Step-by-step explanation:
Probability is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
The probability that the two biscuits were not the same type is 111/190.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of total biscuits = 20
Number of plain biscuits = 12
Number of chocolate biscuits = 5
Number of current biscuits = 3
The probability that two randomly chosen biscuits were not the same type.
= [tex]^{12}C_1 \times ^5C_1[/tex] / [tex]^{20}C_2[/tex] + [tex]^{12}C_1 \times ^3C_1[/tex] / [tex]^{20}C_2[/tex] + [tex]^5C_1 \times ^3C_1[/tex] / [tex]^{20}C_2[/tex]
= 12 x 5 / 190 + 12 x 3 / 190 + 5 x 3 / 190
= (60 + 36 + 15) / 190
= 111 / 190
Thus,
The probability that the two biscuits were not the same type is 111/190.

The garden club earned $15, 15 per hour by weeding neighborhood gardens for t hours. A generous donor has agreed to double their earnings.
How much did the garden club earn in all?
Answer:
The answer should be $30.
Answer:
30 * t
Step-by-step explanation:
The garden club earned $15 per hour by weeding neighborhood gardens for t hours.
A generous donor has agreed to double their earnings.
Double their earnings means we multiply by 2
So earning 15 per hour becomes 2*15 = 30 per hour
Given the number of hours is t
Earnings = $30 times number of hours
Earnings = 30 * t

Can you please Solve for x
Step-by-step explanation:
7x-4+3x+14=180°
10x+10=180
10x=180-10
10x=170
x=170
10
x=17
hope it helps.
Answer: x = 17
Step-by-step explanation:
Alternate interior angles add up to 180°
3x + 14 + 7x - 4 = 180°
Combine like terms
10x + 10 = 180
Subtract 10 from both sides
10x = 170
Divide both sides by 10
x = 17

Solve the equation for all values of x by completing the square.
x^2 + 4x = 32
Answer:
x^2+4x-32=0
(mid-term breaking---4 x 8=32)
x^2+8x-4x-32=0
x(x+8)-4(x+8)
x+8=0 or x-4=0
So x=+4 or x=-8

A.pex VLS Algebra 1: 6.2.4 Practice - HELP NEEDED!!!
The file below is a picture of the problem I'm stuck on... it's hard to explain. I found Coin A and Coin C, but Coin B is confusing me.
Equations to find the value:
Coin A: V=25(1.07)^t
Coin B: V=40(1.05)^t
Coin C: V=60(1.04)^t
V represents the coin's value and t represents what year it is (kind of).
Please help! Even if you can't do the problem, if you explain how to do it to find Coin B, that would be so appreciated! If you are confused about anything, I'll be happy to explain! Thank you!
Answer:
Answer:1.) I chose coin A and B
2.) Coin: B Value: $40 Annual rate: %5
Coin: A Value: $25 Annual rate: %7
3.) Coin: A P: 25 R: 1.07 Function: v = 25(1.07)^t
Coin: B P: 40 R: 1.05 Function: v = 40(1.05)^t
4.) Base: 1+r Initial: P Exponent: t
If R increased, then P would also increase because you must distribute, and you would be distributing R into P there for if R changes then so would P.
5.) Coin A: Initial value: $25 10 years: $25.70 20 Years: $26.40 30 years: $27.10 60 years: $29.20
Coin B: Initial value: $40 10 years: $40.50 20 years: $41 30 years: $41.50 60 years: $43
Coin C: Initial value: $60 10 years: $60.40 20 years: $60.80 30 years: $61.50 60 years: $62.40
6.) Coin A because the value goes up the most and I probably wouldn't be able to keep the coin for more than 60 years because I would lose it.

Pedro has a square practice net in his backyard. The diagonal of the net is 6 feet. Find the length of one side of the net.
Answer:
3sqrt2
Step-by-step explanation:
If a side length is a, then a^2 + a^2 = 36
2a^2 = 36
a^2 = 18
a = 3sqrt2
Or, you can remember that in a square, if you cut it in half diagonally, you get a 45-45-90 triangle, so the sidenglth is diagonal/sqrt2

Answer:
BQ = 16
QE = 8
Step-by-step explanation:
Centroid of a triangle divides the median in the ratio 2 : 1
Here, let BQ = 2x and QE = x
BQ + QE = BE
2x + x = 24
3x = 24
x = 24/3
x = 8
2x = 2*8 = 16
BQ = 16
QE = 8

Solve the equation 2x+3/3 - 3x/2=-4
Fast please
Answer:
x = 6
Step-by-step explanation:
Assuming the equation is
[tex]\frac{2x+3}{3}[/tex] - [tex]\frac{3x}{2}[/tex] = - 4
Multiply through by 6 ( the LCM of 3 and 2 ) to clear the fractions
2(2x + 3) - 9x = - 24
4x + 6 - 9x = - 24
- 5x + 6 = - 24 ( subtract 6 from both sides )
- 5x = - 30 ( divide both sides by - 5 )
x = 6

An airplane can cruise at 570 mph. How far can it fly in 4/3 hours?
Answer:
The plane can fly 760 miles in 4/3 hours.
Step-by-step explanation:
Given that:
An airplane can cruise at 570 miles per hour.
We have to find the distance travelled by train in 4/3 hours.
Distance = Speed * Time
Distance = [tex]570*\frac{4}{3}[/tex]
Distance = [tex]\frac{2280}{3}[/tex]
Distance = 760 miles
Hence,
The plane can fly 760 miles in 4/3 hours.

An escalator in the mall rises to a platform and makes a 30 degrees angle with the ground. If the platform is 76 feet above the ground, how long is the escalator?
9514 1404 393
Answer:
152 feet
Step-by-step explanation:
A triangle modeling the situation has the unknown length as its hypotenuse, and the given platform height as the side opposite the angle. The relevant trig function is ...
Sin = Opposite/Hypotenuse
sin(30°) = (76 feet)/(escalator length)
escalator length = (76 feet)/sin(30°) = (76/0.5) feet
escalator length = 152 feet
