[tex]\boxed {\boxed {\sf \frac{5}{6} \ or \ 0.833}}[/tex]
Step-by-step explanation:
Probability can be found by dividing the favorable outcomes by the total outcomes.
[tex]P=\frac{favorable \ outcomes}{total \ outcomes}[/tex]
In this problem, a favorable outcome is not picking a black jelly bean. The total outcomes is the total number of jelly beans.
[tex]P( \ not \ black \ jelly \ bean)=\frac{not \ black \ jelly \ beans}{all \ jelly \ beans}[/tex]
There are 10 jelly beans that are not black (4 red+5 yellow + 1 pink =10) There are 12 total jelly beans (4 red+ 2 black+ 5 yellow + 1 pink= 12)[tex]P( not \ black \ jelly \ bean )=\frac{10}{12}[/tex]
This fraction can be reduced. Both the numerator and denominator can be divided by 2.
[tex]P(not \ black \ jelly \ bean)=\frac{10/2}{12/2}[/tex]
[tex]P(not \ black \ jelly \ bean)=\frac{5}{6}[/tex]
Probabilty can also be written as a decimal.
[tex]P(not \ black \ jelly \ bean)=0.833[/tex]
The probabilty of not picking a black jelly bean is 5/6 or 0.833

The net of a rectangular prism is shown below. What is the total surface area of the rectangular prism represented by this net?
Answer:
150.88 cm²
Step-by-step explanation:
A rectangular prism also known as cuboid is a three dimensional object with six rectangular faces and eight vertices. It is a prism because it has the same cross section along the length. It is called a rectangular prism because its cross section is rectangular.
The opposite faces of a rectangular prism are equal to each other.
The total surface area (TSA) of a rectangular prism is:
TSA = 2(wl + wh + lh)
where w is the width of the base, l is the length of the base and h is the height of the prism.
From the question, we can see that:
w = 5 cm, l = 7.4 cm and h = 3.1 cm. therefore:
TSA = 2(wl + wh + lh) = 2[(5 * 7.4) + (5 * 3.1) + (7.4 * 3.1)] = 2(37 + 15.5 + 22.94)
TSA = 2(75.44)
TSA = 150.88 cm²

Answer:
14. x = 6, y = 8
15. x = 5, y = 7
16. x = 7, y = 10
Step-by-step explanation:
For a parallelogram, the length across the point of intersection of its diagonals are equal.
So that;
14. PT = TR
QT = TS
So that,
2x = y + 4
2x - y = 4 ...........1
x + 2 = y
x - y = -2 ............. 2
subtract equation 2 from 1,
x = 6
substitute the value of x in equation 1,
2 x 6 - y = 4
y = 12 - 4
= 8
x = 6, y = 8
15. PT = TR
QT = TS
x + 2 = y
x - y = -2 .......... 1
2x = y + 3
2x - y = 3 ......... 2
Subtract equation 1 from 2
x = 5
substitute the value of x in equation 1
5 - y = -2
5 + 2 = y
y = 7
x = 5, y = 7
16. PT = TR
QT = TS
y = x + 3
x - y = -3 ......... 1
2y = 3x -1
3x - 2y = 1 ......... 2
Multiply equation 1 by 2 to have;
2x - 2y = -6 ....... 3
subtract equation 3 from 2
x = 7
substitute the value of x in equation 1
7 - y = -3
-y = -7 -3
-y = -10
multiply through by minus
y = 10
x = 7, y = 10
. Water in a 10 gallon tank is draining at a rate of 2 gallons per hour. Water in a separate tank is filling at a rate of 4 gallons per hour. How long until the tanks have the same amount of water?
Answer:
Step-by-step explanation:
Water in a 10 gallon tank is draining at a rate of 2 gallons per hour.
= 10 - 2x
Water in a separate tank is filling at a rate of 4 gallons per hour.
= 10 + 4x
Equating both Equations together
10 - 2x = 10 + 4x
10 - 10 = 4x - 2x
How long until the tanks have the same amount of water?
Let the time = x
Cara has driven one-fifth of the total distance, d, to her destination.
Which statement explains why both 1/5d and 0.2d can find the distance she has driven?
Multiplying by 1/5 is the same as multiplying by 20%.
Multiplying by 1/5 is the same as multiplying by 2%.
The fraction 1/5 is the same as the decimal 0.8. Therefore, 1/5d can be written as 0.8d.
The expressions are not equivalent.

Answer:
14 lessons can be completed
Step-by-step explanation:
From the question, to get the number of lessons that can be completed, we simply multiply the number of months by 2
Thus, we have that;
G(2) = 2 * 7
G(2) = 14 lessons

Answer:
−10ba+15ba^2
Step-by-step explanation:
The product of the given monomial and binomial is -10ab+15a²b.
The given expression is −5b(2a−3a²).
We need to simplify the polynomial using multiplication.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Binomials are also a kind of polynomials consisting of only two terms. A binomial is defined as an algebraic expression consisting of two terms that are separated by the arithmetic signs, either the addition sign (+) or the subtraction sign (-). When multiplying a monomial by a binomial, we follow the distributive law of multiplication.
Now, 2a×(−5b)−3a²×(−5b)
=-10ab+15a²b
Therefore, the product of the given monomial and binomial is -10ab+15a²b.

What is Unit Conversion?The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.
Given:
1 Cups = 0.0625 Galloon.
Peter make 48 cups of drink.
So, 48 C/ 1 x 1 pt / 2C x 1 qt / 2 pt x 1 gal / 4 qt
= 24 pt x 1 qt / 2 pt x 1 gal / 4 qt

ABCD is a rectangle with sides 6 cm and
8 cm. If its diagonals cross at X, the length
of AX is
Answer:
The length of AX is 5 cm
Step-by-step explanation:
Diagonal of a Rectangle
Given a rectangle of dimensions W by L (as shown in the image below), the diagonal D is the segment that joins two opposite corners of the rectangle.
The diagonals cross at the center of the rectangle in point X, thus the length of AX is half the length of the diagonal.
Note the diagonal is the hypotenuse of a right triangle with legs W and L, thus:
[tex]D^2=W^2+L^2[/tex]
[tex]D^2=6^2+8^2[/tex]
[tex]D^2=36+64=100[/tex]
[tex]D=\sqrt{100}=10[/tex]
The length of the diagonal is 10 cm, thus the required distance is AX=10/2 = 5 cm.
The length of AX is 5 cm

Answer:
The value of the expression 8 - I2g - 5I is -4 ⇒ D
Step-by-step explanation:
The absolute value always gives a positive value IaI = a and I-aI = a
Let us solve the question
∵ The expression is 8 - I2g - 5I
∵ The value of g is g = -3.5
→ To find the value of the expression substitute g by -3.5
∵ 8 - I2g - 5I = 8 - I2(-3.5) - 5I
∴ 8 - I2g - 5I = 8 - I-7 - 5I
∴ 8 - I2g - 5I = 8 - I-12I
→ By using the rule above
∵ I-12I = 12
∴ 8 - I2g - 5I = 8 - 12
∴ 8 - I2g - 5I = -4
∴ The value of the expression 8 - I2g - 5I is -4

Solve the system of linear equations by substitution.
3x + y = -9
y=5x+7
Answer:
The solution is x = -2, y = -3
Step-by-step explanation:
Let's start with the equation 3x + y = -9
Substitute the y for 5x+7 seen in the second equation
Now you have 3x + (5x+7) = -9
Lets solve:
Let's add the x's
Now we have 8x + 7 = -9
Substracy seven from each side
Now we have 8x = -16
Now let's divide 8 on each side
Now we have x = -2
Now lets plug in -2 to the second equation
The second equation is y = 5x+7
When we plug in -2 we get y=5(-2)+7
We multiply
We now have y = -10+7
Add
y = -3
The solution is x = -2, y = -3
Find the solution of the system of equations. 9x +y = 28 3x + 3y = -12
Answer:
x is equal to four, and y is equal to negative eight.
Step-by-step explanation:
Let's solve it rearranging the first equation to define y:
9x + y = 28
y = 28 - 9x
Now we plug it in to the second equation:
3x + 3y = -12
3x + 3(28 - 9x) = -12
And solve for x:
3x + 84 - 27x = -12
-24x = -96
x = 4
Now we can plug that x value into one of the original equations to find the value of y
9x + y = 28
36 + y = 28
y = 28 - 36
y = -8
Let's test our answer by plugging that y value into the other equation, and seeing if we get the same x value:
3x + 3y = -12
3x + 3(-8) = -12
3x - 24 = -12
x - 8 = -4
x = 4
So we know our answer is correct.

Answer:

Step-by-step explanation:
So first find the amount of fence they would need in terms of x, which would be (x - 2) + (3x - 1) + (5x + 8) + (3x - 1) + (x - 2). Then, you know these add up to 106 so you get the equation:
[tex]x-2+3x-1+5x+8+3x-1+x-2 = 106[/tex]
Now, you just have to solve.
First, combine like terms
[tex]13x + 2 = 106[/tex]
Then, subtract 2 from both sides
[tex]13x = 104[/tex]
Next, divide both sides by 13.
[tex]x = 8[/tex]
