Answer:
D
Step-by-step explanation:
The formula for y=
y=(slope)x-(y intercept).
So, we are given -3 and -2 in the places-
y=(slope)-3x-(y intercept)-2
So, the answer is -3 and -2.

write an equation for an arithmic sequence such that t(3)=13 and t(12)=67 HELP ASAP
Answer:
t(n) = 1 +6(n -1)
Step-by-step explanation:
The general term of an arithmetic sequence with first term t(1) and common difference d is given by the formula ...
t(n) = t(1) +d(n -1)
__
Using the two given values of n and t(n), we can find the unknown parameters.
13 = t(3) = t(1) +d(3 -1) = t(1) +2d
67 = t(12) = t(1) +d(12 -1) = t(1) +11d
Subtracting the first equation from the second, we get ...
(67) -(13) = (t(1) +11d) -(t(1) +2d)
54 = 9d . . . . simplify
6 = d . . . . . . divide by 9
Substituting into the first equation gives ...
13 = t(1) +2(6)
1 = t(1) . . . . . . . . subtract 12
Using the found values in the equation for the sequence gives ...
t(n) = 1 +6(n -1)

how to work out 4.2 × 0.03. Show the working not the answer straight! Show how you got the answer.
Answer:
1.26
Step-by-step explanation:
To solve 4.2*0.03, you move the decimal point to the right however many times to both numbers until they are whole numbers.
Doing this, we have 420*3, which took 3 decimal point shifts, so now we do 420*3 to get 1260, and then go 3 decimal places to the left to get the actual answer.
Thus, 4.2*0.03=1.260=1.26

Bill uses rope to outline a location to build a rectangular deck that should be 8 feet wide and 15 feet long. His friend Tyrone lays a 15-foot-long board on the diagonal of the deck area Bill outlined, and it just fits from corner to opposite corner. What should Tyrone tell Bill?
The length of the diagonal outlined by rectangular deck of 8 ft by 15 ft is 17 ft.
What is a rectangle?A rectangle is the quadrilateral (has four sides and four angles) in which each angle measures 90 degrees. Opposite sides are parallel and equal.
The length of the diagonal (x) can be determined using Pythagoras, hence:
x² = 15² + 8²
x = 17 feet
The length of the diagonal outlined by rectangular deck of 8 ft by 15 ft is 17 ft.

Researchers want to determine whether all frozen pizzas have the same proportion of toppings regardless of the brand of pizza. To test this, they sampled randomly pizzas of each brand and recorded their findings in the table.
Brand Topping
Pepperoni Sausage Onion Mushrooms
Digiorno 14 21 17 17
Tombstone 11 8 10 6
Red Baron® 17 13 14 11
Tony's 9 17 15 18
Part A: What are the correct degrees of freedom for this table? (2 points)
Part B: Calculate the expected count for the number of pepperoni for Red Baron® pizza. Show your work.
Part C: Is there sufficient evidence that there is a difference in the proportion of toppings for the different brands of pizza? Provide a statistical justification for your conclusion.
The degree of freedom is 9 and expected amount for the number of pepperoni for Red Baron is 12.867.
How to calculate the degree of freedom?The degree of freedom will be calculated thus:
= (Number of rows - 1) × (Number of columns - 1)
= (4 - 1)(4 - 1)
= 3 × 3 = 9
The expected amount for the number of pepperoni for Red Baron will be:
= (55 × 51) / 218
= 12.867
Also, the p value is 0.6023 and this indicates that there is no sufficient evidence that there is a difference in the proportion of toppings for the different brands of pizza since p value is greater than 0.05.

Answer:
6:10
Step-by-step explanation:
3:5 is equivalent to 6:10 because you multiply both 3 and 5 by 2 and you get 6:10. every thing else is wrong
Answer:
6:10 is the only ratio equivalent to 3:5
Step-by-step explanation:
its not the first one because 5 goes into 30 6 times and 3*6=18 not 13
4:15 isn't possible either because 5 goes into 15 3 times and 3*3=9 not 4

How tall is this building?
Answer:
The building is 86.6 m tall.
Step-by-step explanation:
Coh Cah Toa
Coh: sin(theta) = Opp/Hyp
Cah: cos(theta) = Adj/Hyp
Toa: tan(theta) = Opp/Adj
Using Toa.
tan(theta) = Opp/Adj
tan(60°) = x/50
x = 50 * tan(60°)
x = 50 * √(3)
x ≈ 86.60254038
x = 86.6 m
Find the length of the third side. If necessary, round to the nearest tenth.
4
Answer:
x=2.6
Step-by-step explanation:
We can use the Pythagorean theorem to find the third side
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
3^2 + x^2 = 4^2 where x is the unknown side
9 + x^2 = 16
Subtract 9 from each side
x^2 = 16-9
x^2 = 7
Take the square root of each side
sqrt(x^2) = sqrt(7)
x =2.645751311
Rounding to the nearest tenth
x = 2.6
Answer:
2.65
Step-by-step explanation:
take the length of the third side as x
so,take Pythagoras theorem
4^2=3^2+x^2
16=9+x^2
x^2=16-9
x^2=7
x=√7
x=2.645
x=2.65

Lindiwe is twice as old as Preeya and six years older than Sue . Their combined ages total 39 years . How old is Lindiwe
Answer:
Lindiwe is 18
Step-by-step explanation:
Lindiwe = L
Preeya = L/2
Sue = L-6
Their combined ages total 39 years
L+(L/2) + L-6 = 39
2.5L = 45
L=18
Lindiwe=18
Preeya= 9 (half of Lindiwe)
Sue = 12 (6 lessthan Lindiwe)
18+9+12 = 39

Distribute to create an equivalent expression with the fewest symbols possible.
6(3c - 5d + 6) =6(3c−5d+6)=6, left parenthesis, 3, c, minus, 5, d, plus, 6, right parenthesis, equals
Using the distributive property, it is found that the equivalent expression is:
18c - 30d + 36
What is the distributive property?It is a property that the outside term multiplies each of the inside terms.
In this problem, the expression is:
6(3c - 5d + 6).
Hence, we apply the property, with the outside term 6 multiplying each of the inside terms, hence the equivalent expression is given by:
6(3c - 5d + 6) = 18c - 30d + 36.

Find the value of m, expressed as a common fraction so that this relation is not a function.
{(-2m+1,-4),(-6m+8,0)}
Answer:
m = 7/4Step-by-step explanation:
If the two points have same input with different outputs, then this relationship is not a function, according to definition of the function.Make the x-values same and solve for m
- 2m + 1 = - 6m + 86m - 2m = 8 - 14m = 7m = 7/4Let's see
x must be equal on both sides as it's not a function
-2m+1=-6m+84m=8-14m=7m=7/4ALL of the Students at Beach Middle School voted for a trip to the zoo or the aquarium.
- 25% of the students voted for the aquarium
- 120 students voted for the zoo
What is the total number of students at Beach Middle School?
Answer:
160
Step-by-step explanation:
If there were only 2 options, all the people who didn't pick one chose the other one.
So if 25% of the people voted for the aquarium the remaing 75% voted for the zoo.
Since three times as many people voted for the zoo, we can see that 120/3=40, so 40 people chose the aquarium.
To find the total number of students, we add 120 and 40 to get 160
ANSWER ASAP PLS! WILL GIVE MAX PTS Three times x is 13 less than y. The sum of x and two times y is 12. Write two equations and graph to find the value of y.
Group of answer choices
y = -2
y = 2
y = 7
y = -7
Solution For Given Question
Three times x is 13 less than y
[tex]3x = y - 13 \\ = > 3x + 13 = y[/tex]
The sum of x and two times y is 12.
[tex]x + 2y = 12[/tex]
Replacing Value of Y with 3x + 13
[tex]x + 2y = 12 \\ \\ \implies x + 2(3x + 13) = 12 \\ \\ \implies x + 6x + 26 = 12 \\ \\ \implies7x = 12 - 26 \\ \\ \implies 7x = - 14 \\ \\ \implies x = \cancel\frac{ - 14}{7} \\ \\ \implies x = - 2[/tex]
Now we need to fine Value of'y' i e.,
[tex]y = 3x + 13 \\ \\ \implies y = 3( - 2) + 13 \\ \\ \implies y = - 6 + 13 \\ \\ \implies y = 7[/tex]
[tex] \therefore \text{option c.(y = 7) is your answer}[/tex]
Hope this helps
