Answers
Answer:
I have given it step by step below.
Step-by-step explanation:
(i) Mean = sum of observations/total no. of observation
= 23 + 20 + 4 + 19 + 28 + 35 + 25 + 0 +1 + 30/ 10
= 185/10
= 18.5
(ii) additional 35 runs
New Mean
=previous total + 35/10 + 1 (the 1 gets added in denominator because of the additional observation)
= 185 + 35/11
= 220/11
= 20

Answers
Answer:
c = 3
c = -3
(There are two because absolute value :P)
Step-by-step explanation:
u = 7i + 24j
u = (7, 24)
||c * u|| = 75
75 = || c [tex]\sqrt{7^{2}+24^{2} }[/tex] ||
75 = || c [tex]\sqrt{625}[/tex] ||

The dimensions of the portrait are attached.
The total area of the portrait is represented by its width 5+x and its length x+1.
We know by definition that the area of a rectangle is
[tex]A= w \times l[/tex]
Where [tex]w[/tex] is the width and [tex]l[/tex] is the length.
Using the given expressiones, we have
[tex]A=(5+x)(x+1)=5x+5+x^{2} +x=x^{2} +6x+5[/tex]

Which congruence theorem can be used to prove △WXZ ≅ △YZX? Triangles W X Z and Y Z X share side X Z. Angles W X Z and X Z Y are right angles. Angles X W Z and X Y Z are congruent. AAS ASA SAS HL
Answers
Answer:
The correct option is AAS.
Step-by-step explanation:
Consider the diagram below.
It is provided that The triangles △ WXZ and △ YZX share a side XZ.Angles ∠WXZ and ∠XZY are right angles.Angles ∠XWZ and ∠XYZ are congruent.If two angles are congruent it implies that they are same in degrees or radians.
So, the angles ∠XWZ and ∠XYZ are equal.
So, in the diagram below, one of the triangles have two angles that are equal to the corresponding angles on the other triangle and the two triangles share a side.
Then according to the Angle-Angle-Side (AAS) statement the triangles △ WXZ and △ YZX are congruent.
Thus, the correct option is AAS.
The congruence theorem that can be used to prove that △WXZ ≅ △YZX is; AAS
We are told that;ΔWXZ and ΔYZX share side XZ
∠WXZ and ∠XZY are right angles
∠XWZ and ∠XYZ are congruent
Now, from the given parameters, we can say that from reflexive property of congruence, XZ is congruent to itself and thus, we have one side of both triangles that is congruent.Secondly, since ∠WXZ and ∠XZY are right angles, it means they are equal and therefore congruent to each other.Lastly, we are told that ∠XWZ and ∠XYZ are congruent.In summary, we have 2 corresponding angles and one corresponding side that are equal but the corresponding side is not with the included angles and as such the triangles are congruent by AAS Congruency.Read more about AAS Congruency at; https://brainly.com/question/7727792
A pebble drops from a balcony that is 80 feet above the ground. The pebble lands on the top of a sign that is 16 feet high. The function y=80−16t2 represents the height y (in feet) of the pebble t seconds after dropping from the balcony. How many seconds does the pebble drop before hitting the sign?
The pebble hits the sign after ______ seconds.
Answers
Answer:
t =2 seconds
Step-by-step explanation:
We have, a function that represents the height y of the pebble after dropping the balcony as follows :
[tex]y=80-16t^2[/tex]
The pebble lands on the top of a sign that is 16 feet high.
It is required to find the time does the pebble drop before hitting the sign. The above equation becomes,
[tex]80-16t^2=16\\\\-16t^2+80=16\\\\-16t^2=64\\\\t^2=4\\\\t=2[/tex]
So, the pebble hits the sign after 2 seconds.

Mrs. Samuelson had $350 to spend on a field trip for herself and 18 students. Admission was $12.50 per person and lunch cost about $5.00 per person. Write an equation to describe the amount of money left after the trip.
Answers
Step-by-step explanation:
Answer is $17.5
It says Mrs. Samuelson had $350 to spend on a field trip for herself and 18 students. so there are 19 people. Multiply 12.50*19 you get 237.5.
It also says lunch cost about $5.00 per person. Multiply 5.00*19 you get 95.
Add 95 to 237.5.
You get 332.5
Subtract 350 by 332.5.
Equation: 350-(19*12.50)+(19*5.00)

Answer:
c tomato 2.5
pepper = 3.5
Step-by-step explanation:
Let t= the price of tomato plants
p =the price of pepper plants
3t+ 4p = 21.50
5t+ 2p = 19.50
Multiply the second equation by -2
-10t -4p =-39
Add this to the first equation to eliminate p
-10t -4p =-39
3t+ 4p = 21.50
---------------------
-7t = -17.5
Divide by -7
t = 2.5
Now find p
5t+ 2p = 19.50
5( 2.5) + 2p = 19.50
12.5+2p = 19.50
Subtract 12.5 from each side
2p =7
p =3.5
We want the price of 1 tomato and 1 p
3.5+2.5
Answer:
C
Step-by-step explanation:
Let t = price of tomato plants
and p = price of pepper plants
3t + 4p = 21.50 ...... (1)
5t + 2p = 19.50 ..... (2)
Multiplying eqn. (2) by - 2
(5t + 2p) * (- 2) = (19.50) * (- 2)
- 10t - 4p = - 39
-10t - 4p = - 39
3t + 4p = 21.50
____________
-7t = -17.5
t = 2.5
Putting t = 2.5 in eqn. (2), we get:
= 5 * (2.5) + 2p = 19.50
12.5 + 2p = 19.50
2p = 7
= 3.5
Price of one tomato and one pepper plant = 3.50 + 2.50

if (-3,-4) is a point on the line y =mx+2 ,find the value of m
Answers
Answer:
m = 2
Step-by-step explanation:
Given
y = mx + 2
Since (- 3, - 4) is a point on the line then it satisfies the equation.
Substitute x = - 3 and y = - 4, the coordinates of the point, into the equation and solve for m, that is
- 4 = - 3m + 2 ( subtract 2 from both sides )
- 6 = - 3m ( divide both sides by - 3 )
2 = m

someone empties 6 jugs of milk into a container. -Each jug contains 4 L of milk. -He uses the container of milk to fill cartons. -Each carton requires 250 mL of milk. How many cartons will he be able to fill?
Answers
Answer:
96 cartons
Step-by-step explanation:
Capacity of one jug = 4 L
Capacity of 6 jugs = 4 * 6 = 24 L
Capacity of milk in the container = 24 L
one litre = 1000 ml
24 liter = 24 * 1000 = 24000 ml
Number of cartons = Total capacity of milk/Capacity of milk in one carton
= 24000÷250
= 96 cartons
1 container receives 6 jugs of milk (1 jug of milk=4L)
6×4L=24L
The 1 container of milk is used to fill cartons of milk
The 1 container of milk is used to fill cartons of milk (1 carton=250 ml)
Step 1; Convert ml to L
250ml ÷ 1000 = 0.25L
Step 2; Divide
24L ÷ 0.25L = 96
Ans: 96 cartons of milk can be filled.

What is the solution to the equation Two-thirds x + 1 = one-sixth x minus 7?
Answers
Answer:
x = -16
Step-by-step explanation:
2/3x +1 = 1/6x - 7
Multiply each side by 6 to get rid of the fractions
6(2/3x +1) = 6(1/6x - 7)
4x +6 = x - 42
Subtract x from each side
4x-x +6 = x-x-42
3x +6 = -42
Subtract 6 from each side
3x +6-6 = -42-6
3x = -48
Divide each side by 3
3x/3 = -48/3
x = -16
So the right answer is -16
