Anna and Paddy take part in the same fun run.
Anna completed the fun run in 2 hours.
Her average speed was 6 kilometres per hour.
Paddy completed the fun run in 90 minutes.
(a) Work out Paddy's average speed in kilometres per hour.

Answers

Answer:

I wanna say 4.6 kmph

Step-by-step explanation:

6(average) /2(hr)=3kmph

1.20(hr) / 6 (kmph) = 4.6

If Anna and Paddy take part in the same fun run. Anna completed the fun run in 2 hours. Her average speed was 6 kilometres per hour. Paddy completed the fun run in 90 minutes. Then 4.5 km/h is Paddy's average speed

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Anna and Paddy take part in the same fun run. Anna completed the fun run in 2 hours.

Her average speed was 6 kilometres per hour.

Paddy completed the fun run in 90 minutes.

We need to find paddys average speed in kilometres per hour.

Let us convert 2 hrs to minutes=120 minutes

6/120=x/90

Apply cross multiplication

90×6=120x

540=120x

Divide both sides by 120

x=4.5

Hence 4.5 kilometer per hour is the Paddy's average speed.

After a while, Jada picks up a coin that seems different than the others. She notices that the next day, only half of the coin is left!
On the second day, only 1/4 of the coin is left.
On the third day, 1/8 of the coin remains.
What fraction of the coin remains after 6 days?

What fraction of the coin remains after 28 days? Write an expression to describe this without computing its value.

Does the coin disappear completely? If so, after how many days?

Answers

Answer:

After 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

Step-by-step explanation:

Since after a while, Jada picks up a coin that seems different than the others, and she notices that the next day, only half of the coin is left, while on the second day, only 1/4 of the coin is left and, on the third day, 1/8 of the coin remains, to determine what fraction of the coin remains after 6 days, what fraction of the coin remains after 28 days and determine if the coin will disappear completely, the following calculation must be performed:

1/2 ^ 6 = X

0.015625 = X

1/64 = X

1/2 ^ 28 = X

0.0000000037252902984619140625 = X

1/268435456 = X

Thus, after 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

An online retailer wants to study whether more lenient return policies increase purchasing behaviors. They
select a random sample of 2000 customers who have made purchases in the past year.
They use a random number generator to select 1000 customer account numbers to assign to the treatment
group. The remaining 1000 customers are assigned to the control group.
What type of experiment design is this?

A) randomized block
B) stratified
C) completely randomized
D) marched pairs
E) cluster

Answers

Answer: Completely Randomized

Step-by-step explanation:

effect of one primary factor rather than many different variables

As per the question the retailer wants to study the return policy that can increase the buying behavior and selects a random sample of 2000.

He uses matched pair of designs in his experiment design in which participants of the same traits get grouped in pairs. After which within each pair, one participant gets randomly allotted to either the treatment, and the other is assigned to the other part.

Hence the option D is correct.

Lateral area of the cylinder

Computation:

Lateral area of the cylinder = 2πrh

Lateral area of the cylinder = 2(22/7)(5)(2)

Lateral area of the cylinder = 2(22/7)(10)

Lateral area of the cylinder = (440/7)

Lateral area of the cylinder = 62.85 cm²

PLEASE HELP :DDDDDDDDDD

Answers

Ok start off by finding the base first and the equation of finding the area of the square is A=bh
A=11 x 11= 121 cm^2

Next find the area of one triangle and the equation is A=1/2bh
A=1/2(11)(10)
A=55 cm^2

Multiply the area of one triangle by 4 since there are four triangles and it should equal to 220 cm^2. You then add this to the base and the final answer should be 341 cm^2.

I hope this helps

Answer:

341 cm²

Step-by-step explanation:

A=11 x 11= 121 cm²

A=1/2(11)(10)

A=55 cm²

Multiply the area of one triangle by 4 since there are four triangles.

=220 cm²

220+121=341cm²

Function is defined by f(x) = x2 - 4x + 8. The graph of function g is shown.
Let h represent the x-coordinate of the vertex of the graph of y = f(x). Let
represent the x-coordinate of the vertex of the graph of y = g(x). What is the
value of h-j?

Answers

The value of h -j is -5.

We have the function, f(x) = x² -4x + 8

Now, vertex

h = x = -b/2a

h = x = -(-4) / (-2)

h = x = -4/2

h= x = -2

Now, according to the graph

j = x= 3

So, h - j

= -2 - 3

= -5

Hi! So marking up means to raise the price or increase it.

185 is the whole, a whole is 100

and we need to raise it by 20% so add these two together to get 120%, turn this into a decimal is 1.2, now to find and increase we multiply it by the original price.

1.2 x 185 = 222
