A six-sided die is rolled. What is the probability of NOT rolling a 1 or 6?
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
"The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible".
Here the number of favorable outcomes is 4, and the number of total outcomes is 6.
So the probability of NOT rolling a 1 or 6 is [tex]\frac{4}{6}[/tex] which is [tex]\frac{2}{3}[/tex]
The length of a rectangle is 4 centimeters is longer than its width. What are the possible integral widths if the area of the rectangle is less than 437 square centimetres?
Answer: 23
Step-step by explanation:
w(w+4)=437
w^2+4w-437=0
(w+23)(w-19)=0
w=19,-23
w<19
l<23!!
The possible integral width of the rectangle is 23.
What is a rectangle?A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.
Given that the length of a rectangle is 4 centimeters is longer than its width. The area of the rectangle is less than 437 square centimeters
The width of the rectangle will be calculated as below:-
w(w+4)=437
w²+4w-437=0
(w+23)(w-19)=0
w=19,-23
w <19
w < 23
Therefore, the possible integral width of the rectangle is 23.

Answer:
-5x² + 2x + 3
Step-by-step explanation:
Since its a trinomial, it has three terms.
Since it has a degree 2, the highest degree is 2 and will usually be the first term.
The coefficient of the first term must have a -5.
Standard form is like ax² + bx + c
Where a,b, and c are variables.
So, -5x² + 2x + 3 should work
We know the standard form
ax^2+bx+c=0Now
a=-5So the expression is given by
-5x^2+3x+8=0Riddle

For the following arithmetic sequence: 4, ___, ____, ____, 24 a)Describe the term-to-term rule.
Answer: 4,9,14,19,24
The term to term rule is "add 5"
Step-by-step explanation:
From the question,
First term = a = 4
Fifth term = a+(n-1)d = a+(5-1)d = a+4d = 24
Since a + 4d = 24
We slot on the value of a
a + 4d = 24
4 + 4d = 24
4d = 24 - 4
4d = 20
d = 20/4
d = 5
The term to term rule will be "add 5"
The arithmetic sequence will be:
4
4+5 = 9
9+5 = 14
14+5 = 19
19+5 = 24
Functions p and q are defined by these equations: p(x) = 5x + 30 q(x) = 11x − 24 What is (q − p)(6)? A. -42 B. 42 C. 18 D. -18
Answer
D. -18
Step-by-step explanation:
p ( x ) = 5x + 30, q ( x ) = 11x -24
( q - p ) (6 ) = 11x -24 - ( 5x + 30 )
= 11.6 - 24 - 5.6 - 30
= 66 - 24 - 30 -30
= 42 -30 -30
= 12 -30
= -18

Triangle XYZ, with vertices X(-2, 0), Y(-2, -1), and Z(-5, -2), undergoes a transformation to form triangle X′Y′Z′, with vertices X′(4, -2), Y′(4, -3), and Z′(1, -4). The type of transformation that triangle XYZ undergoes is a (1: translation 2 units left and 6 units up, 2: Reflection across the y-axis, 3: Reflection across the x-axis, 4: Translation 6 units right and 2 units down, 5: Dilation by scale factor 2. Choose the Correct answer.
Answer:
4. Translation 6 unit right and 2 units down.
Step-by-step explanation:
Let' take the point and it's corresponding image.
x(-2,0) and x'(4,-2)
Now,let's find the translation
-2+? =4
0+? =-2
Now, if we solve each for ?, we get
-2+?=4, gives ? =6
0+?=-2 gives ?=-2
It means the translation is move right 6 units and down 2 units.
So, option 4 is right.

To see which amount of tickets is the best deal, look at the unit price of each.
To do this, divide the cost of the tickets by the number of tickets to see how much money a single ticket costs in each of the deals.
$.50/1 = $.50$5.00/12 = $.42 $10.00/25 = $.40$25.00/50 = $.50$50.00/120 = $.42A) Buying 25 tickets for $10.00 offers the best deal because each ticket is only worth $.40, compared to the other deals where each ticket is worth $.50 or $.42.
B) Usually, businesses offer a better discount the more of a good someone buys due to marketing purposes. I would suggest that the students make the discount higher as the number of tickets increases. Therefore, more people would be willing to buy more tickets and both the consumer and seller will be happy because more discounts (consumer = happy) and more profit (more ticket sales -> business = happy).

O
B. The $8 package, because each pencil costs $0.63.
C. The $12 package, because each pencil costs $1.50.
O D. The $12 package, because each pencil costs $0.66.
Answer:
C. The $12 package, because each pencil costs $1.50
Step-by-step explanation:
The answer is C because when dividing the cost by the number of pencils, the amount per pencil is less for the 12 dollar package and you get more pencils.

what is the formula for the nth term of the given sequence 100, 20, 4, …
Answer:
[tex]a_n=100 \left(\dfrac15\right)^{n-1}[/tex]
Step-by-step explanation:
General equation of geometric sequence: [tex]a_n=ar^{n-1}[/tex]
Given:
a₁ = 100a₂ = 20a₃ = 4[tex]\implies a_1=a=100[/tex]
[tex]\implies a_2=100 \cdot r=20[/tex]
[tex]\implies a_3=100 \cdot r^2=4[/tex]
Common ratio:
[tex]r=\dfrac{a_3}{a_2}=\dfrac{4}{20}=\dfrac15[/tex]
Therefore:
[tex]a_n=100 \left(\dfrac15\right)^{n-1}[/tex]
