Point Z is translated right 1, down 8.
Which is the coordinate pair for the translated point Z'?
(4, –1)
(1, 4)
(1, –4)
(–8, 1)
Answers
Answer:
(1, –4)
Step-by-step explanation:
Since, Z is translated right 1 and down 8, so x- coordinate would be 1 and y-coordinate would be - 4
Hence the coordinate pair for the translated point Z' would be (1, - 4).

10) Two number cubes are rolled and the results are added. (There are 36 possible
outcomes.) What is the probability the sum is equal to 2?
Answers
Answer:
2.7%
Step-by-step explanation:
The first thing to take into account, how could the sum be and the only way is that in each numerical cube, get a 1, because the other option is 2+ 0, but it is assumed that both cubes are numerical and on each side there are number.
Therefore, the probability would be that in each die 1 appears, they tell us that there are 36 possible results in the two dice and this would be 1 of those 36 results, which means that the probability would be:
1/36 = 0.027
What 2.7% means is the probability

Answers
Answer: 3150 miles
Step-by-step explanation: Ok, let's break it down...
180 ÷ 2 = 90 / The train travels 90 mph....
90 * 7 = 630 / The jet travels 630 mph....
630 * 5 = 3150 / The jet will travel 3150 miles in 5 hours, I hope this helps!

find the value of N please!!
Answers
Answer:
n = - 5
Step-by-step explanation:
Using the rules of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]
[tex]\frac{a^{m} }{a^{n} }[/tex] ⇔ [tex]a^{(m-n)}[/tex]
Consider the left side
[tex]\frac{y^4.y^{n} }{y^2}[/tex]
= [tex]\frac{y^{4+n} }{y^2}[/tex]
= [tex]y^{4+n-2}[/tex]
= [tex]y^{2+n}[/tex], then
[tex]y^{2+n}[/tex] = [tex]y^{-3}[/tex]
Since the bases on both sides are the same, equate the exponents
2 + n = - 3 ( subtract 2 from both sides )
n = - 5

Answers
Answer: T = 4c + 4t + 3s
Step-by-step explanation:
Stocks contains:
4-legged chairs
4-legged tables
3-legged stools
So, 1 chair has legs = 4
So, c chairs has legs = 4c
1 table has legs = 4
So, t tables has legs = 4t
1 stool has legs = 3
So, s stools has legs = 3s
Let T denotes the total no. of legs
So, the total number of furniture legs in aisle 2 :
T = 4c + 4t + 3s

The point (2,–5), when reflected across the origin, maps onto the point _______. answers : (–5,2) (5,–2) (–2,5) (2,5)
Answers
The points (2, -5) when reflected across the origin becomes (-2, 5)
What is reflection?Reflection is a mathematical transformation of a shape by moving the vertices of the shape a distance equal to the distance between the line of reflection and the original point.
Other types of transformational processes are: Rotation and translation.
Analysis:
In transformation in the origin, the line of reflection is x = 0 and y = 0.
Which means both coordinates of the point would be changed.
At x = 2, 2 is 2 units from the origin. The only point which is 2 units away from the origin in the opposite side is -2.
Also at x = -5, that is 5 units away from the origin. The only point 5 units away from the origin is 5. so the new coordinate is 5.
In conclusion, the new point after reflection would be (-2, 5)

Answer: (a) 4
(b) 5
(c) 14
(d)
Class interval Class mark
30 - 35 [tex]\dfrac{35+30}{2}=32.5[/tex]
35 - 40 [tex]\dfrac{35+40}{2}=37.5[/tex]

45 - 50 [tex]\dfrac{45+50}{2}=47.5[/tex]
50 - 55 [tex]\dfrac{50+55}{2}=52.5[/tex]
Step-by-step explanation:
The data of 40 persons is given as :
Weights (in kg) Frequency
30 - 35 6
35 - 40 13
40 - 45 14
45 - 50 4
50 - 55 3
(a)
Lower limit is the lowest number in a class interval .
So, is the lower limit of fourth-class interval (45 - 50) is 4.
(b)
Class size = Upper limit - lower limit
So, Class size of first class interval = 35-30=5
Thus , class size of each interval is 5. [ class size remains same]
(c)
Highest frequency in table = 14 which is corresponding to 40 - 45 .
Thus , 40 - 45 is the class interval has the highest frequency.
(d)
Class mark is the mid value of each class interval.
Class interval = [tex]\dfrac{(\text{Upper limit+Lower limit})}{2}[/tex]
Class interval Class mark
30 - 35 [tex]\dfrac{35+30}{2}=32.5[/tex]
35 - 40 [tex]\dfrac{35+40}{2}=37.5[/tex]
40 - 45 [tex]\dfrac{40+45}{2}=42.5[/tex]
45 - 50 [tex]\dfrac{45+50}{2}=47.5[/tex]
