What this question is asking us is
A) From -40C to 5 0c How much did it rise
The formula for this would be
Risen Temperature - Initial Temperature
The risen temparauture is 5 so we plug the 5 in first then the 4 so it would look like
5-(-4)=9
And remeber when you have 2 negatives it becomes a positie, 5+4=9
The asnwer for A is 9 degress
B) The tempurater then fell by 7 degress from 5 so we just have to do
5 - 7
which is -2 Celcius
Answer:
a was i believe 10 degrees and b dropped 3- degrees
Step-by-step explanation:
Because 4- 3- 2- 1- 0 1 2 3 4 5

And for b 5 dropped from 7 degrees just take 5 now ur at 0 and u have 3 more to take boom ur at 3- hope this hellped :)
In 1898, L. J. Bortkiewicz published a book called The Law of Small Numbers, where using data he collected for twenty years, he showed that the number of soldiers killed by horse kicks each year in the Prussian army followed a Poisson distribution with a mean of 0.61. What is the probability that there will be exactly three deaths in two years?
hurry please will pick brainly and step by step appreacite it
Answer:
given : 0.61 per year
formula poisson probability : p(x=k)=xke-x/k!
(a) The parameter λ is the product of the rate per year and the number of years. The number of years is 1 year in this case.
λ=0.61×1=0.61
Evaluate the formula of the Poisson probability at k=0,1:
P(X=0)= 0!
(0.61)
0
e
−0.61
≈0.5434
P(X=1)=
1!
(0.61)
1
e
−0.61
≈0.3314
Add the corresponding probabilities:
P(X≤1)=P(X=0)+P(X=1)=0.5434+0.3114=0.8748
Use the complement rule:
P(X>1)=1−P(X≤1)=1−0.8748=0.1252
Note: The solution in the back of the book is the probability of at least one death instead of more than 1 death, thus the solution in the back of the book is not correct.

In the card game Set, each card features a number of shapes, with four attributes:
Number: The number of shapes is 1, 2, or 3.
Color: Each shape is red, purple, or green.
Shape: Each shape is oval, diamond, or squiggle.
Shading: Each shape is hollow, shaded, or striped.
There is exactly one card for each possible combination of attributes.
In the game, several of the cards are dealt out, and the goal is to find a set. A set is formed by three cards, where for each attribute, either all three cards are the same, or all three cards are different. When three cards form a set, we can also count the number of attributes for which all three cards are the same.
(a) How many cards are in a complete deck of Set?
(b) How many unique sets are there?
(c) Find the number of sets where all three cards are the same for exactly 0 attributes.
(d) Find the number of sets where all three cards are the same for exactly 1 attribute.
(e) Find the number of sets where all three cards are the same for exactly 2 attributes.
(f) Find the number of sets where all three cards are the same for exactly 3 attributes.
A) The number of cards that are in a complete deck of Set is; 81
B) The number of unique sets are; 36
How to find the combination of a set of cards?a) We are given;
Number of shapes = 1, 2 or 3
Colour = Red, Purple or Green
Shape = Oval, Diamond or Squiggle
Shading = Hollow, Shaded or Striped
Now, since a set is formed by all 3 cards, then we can say that;
Number of cards in a complete deck of set = 3⁴ = 81 cards
(b) Let us first find all sets = 3² * 4 * 3 = 108.
Thus;
Unique sets = 108/3
= 36 unique sets.
(c) There are 3 ways to choose the number of the cards from the given order.
For the second one, there 2 choices, and then there is only 1 choice. Thus; Number of ways to choose the numbers = 3 * 2 * 1 = 6.
For the other attributes;
Number of ways = 6 * 6 * 24 *6 ways.
Now, since the order of cards doesn't matter in a set, then the number of sets where all three cards are the same for exactly 0 attributes is;
(6 * 6 * 24 *6)/3! = 864 sets
(d) If all the colors are the same, then;
Number of sets = 6 * 24 * 6/3! = 144 sets.
If all the numbers are the same, then there are 144 sets which is also same for shapes and shading. Thus;
The number of sets where all three cards are the same for exactly 1 attribute is; 4 * 144 = 576
(e) There are C(4, 2) = 6 ways of choosing two attributes.
For each of the two attributes, there are 3 options.
For the other two attributes, there are 3 ways of assigning the choices. Thus, number of sets = 6*3*3*3*3 = 486 sets.
(f) There are C(4,3) = 4 ways of choosing which attributes are the same. There are 3*3*4 = 36 ways to assign which is which for each of these three attributes, and there are 4 ways to assign the choices for the fourth attribute. Thus;
The number of sets where all three cards are the same for exactly 3 attributes = 4*36*4 = 576 sets.

What are the vertices of A'B'C if ABC is dilated by a scale factor of 2?
The vertices of A'B'C' if A(0, 10), B(8, 6), C(4, 2) is dilated by a scale factor of 2 are;
C. A'(0, 20), B'(16, 12), C'(8, 4)Which method can be used to find the vertices of A'B'C'?Given that triangle ABC is dilated by a scale factor of 2, we have;
A'B' = 2 × AB
A'C' = 2 × AC
B'C' = 2 × BC
Length of AB = √((8-0)^2 + (6-10)^2) = 4•√5
Length of AC = √((4-0)^2 + (2-10)^2) = 4•√5
Length of BC = √((8-4)^2 + (6-2)^2) = 4•√2
By multiplying the given coordinates by the scale factor, we have;
A' = 2 × (0, 10) = (0, 20)
B' = 2 × (8, 6) = (16, 12)
C' = 2 × (4, 2) = (8, 4)
A'B' = √((16-0)^2 + (12-20)^2) = 8•√5
A'C' = √((8-0)^2 + (4-20)^2) = 8•√5
B'C' = √((16-8)^2 + (12-4)^2) = 8•√2
Therefore when we have;
A'(0, 20), B'(16, 12), C'(8, 4), we get;
A'B' = 2 × ABA'C' = 2 × ACB'C' = 2 × BCThe correct option is therefore;

The Smiths have a pool that is 20 feet by 35 feet. A 5 foot wide deck completely surrounds the pool. The average depth of the pool is 6 feet. How much surface area is covered by the proposed pool deck?
Answer:
550 square feet
Step-by-step explanation:
There are 4 areas where the pool deck is situated on:
Top, Left, Right, and Bottom of the pool.
So if the deck is 5 feet wide:
Top = (35 feet * 5 feet) = 175
Bottom = (35 feet * 5 feet) = 175
Left = (20 feet * 5 feet) = 100
Right = (20 feet * 5 feet) = 100
175 + 175 + 100 + 100 = 550 square feet

The value of n from the set {6, 7, 8, 9} that holds true for 4n − 12 < 2n + 2 is
The value of n that satisfies the inequality is 6.
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Given:
4n − 12 < 2n + 2
For n= 6
4(6) - 12 = 12
2(6) + 2 = 14
Thus, n=6 satisfies
For n= 7
4(7) - 12 = 16
2(7) + 2 = 16
Thus, n=7 not satisfies
For n=8
4(8) - 12 = 20
2(8) + 2 = 18
Thus, n=8 not satisfies.
For n= 9
4(9) - 12 = 24
2(9) + 2 = 20
Thus, n=9 not satisfies.

PLEASE HELP ME ASAP!!!!
Part A: Identify the diagonals in the parallelogram.
Part B: Determine the value for x and y. Show your work.
Part C: Identify the length of each diagonal. Show your work.
Part A
[tex]\overline{AC}[/tex] and [tex]\overline{BD}[/tex]
Part B
Diagonals of a parallelogram bisect each other, so
[tex]BE=ED \implies 2x+3=3y-4 \implies 3y=2x+7 \implies y=\frac{2}{3}x+\frac{7}{3}\\\\AE=EC \implies y+4=4x-6 \implies y=4x-10[/tex]
Solving by substitution,
[tex]\frac{2}{3}x+\frac{7}{3}=4x-10[/tex]
Multiplying both sides by 3,
[tex]2x+7=12x-30\\\\37=10x\\\\x=3.7[/tex]
So, [tex]y=\frac{2}{3}\left(\frac{37}{10} \right)+\frac{7}{3}=\frac{24}{5}[/tex]
Part C
[tex]BE=ED=2(3.7)+3=10.4\\\\AE=EC=4(3.7)-6=8.8[/tex]
[tex]\therefore BD=2(10.4)=20.8, AC=2(8.8)=17.6[/tex]
