A sampling interval of 5 (selecting every fifth unit) was used to select a sample from a population of 1000. how many elements are to be in the sample?

We get that a / b will also be less than e / f.

A rational number means a number that can be written in the form of p / q.

We are given the three rational numbers:

a / b , c / d and e / f.

We are also given that:

a / b < c / d  …(1)

c / d < e / f    …(2)

Multiply (1) and (2), we get that:

a / b × c / d < c / d × e / f

Dividing both sides by d / c, we get that:

a / b < e / f

So, a / b will also be less than e / f.

Therefore, we get that a / b will also be less than e / f.

Answer:

The first one is x=3y-5

The second one is y/2 + 3

Step-by-step explanation:

For the first one you have to switch sides

X-3=3y-8

X - 3=3y-8

Then you add three to both sides

X-3+3=3y-8+3

Then simplify

X=3y-5

For the second one

you switch sides then add 5 to both sides then simplify

2x-5+5=y+1+5

Y/2 +3 or

Y+6 /2

Answer:

x<-4

Step-by-step explanation:

You just subtract the 1 from both sides and the sign stays the same UNLESS you are dividing by a negative number, then it will change. Good luck on your hw :)

Answer:

4.64x10^6

Step-by-step explanation:

The supply curve swings left along the demand curve, raising the price of the pizza shops to close. If individuals just have a greater interest in beer, the demand curve will shift to the right, which will cause the price to rise as the supply curve is moved to the right. Apply this knowledge to the rest of the analysis.

If the price increase was modest, then the movement in supply in the pizza market must have outweighed the shift in demand. The supply shift in the pizza market must have been greater than the demand shift if the equilibrium amount of pizzas declines. The price of pizzas must have changed as a result of whichever modification happened first. If the amount of pizzas in the equilibrium market falls, the demand shift must have been greater than the supply shift.

The demand curve changes to its proper position. It happens as a result of people switching to eating pizza instead of pizzas. The new equilibrium price rises as a result of the new demand curve and the existing supply curve.

A rise in supply and a decline in demand will result in a decrease in the equilibrium price, but the impact on the equilibrium quantity cannot be predicted. Consumers now place less significance on price for any quantity, and producers are willing to simply accept a lower price; as a result, the price will decrease.

Answer:

90 minutes or 1 hour and 30 minutes

Step-by-step explanation:

Hey there!

In order to find out how long Amy studied for her math test, all we need to do is divide 3 hours by 2

First of all, we can convert 3 hours to 180 minutes since there are 60 minutes in 1 hour

Now, we divide 180 and 2

180/2 is 90

The answer for the given question is 92 Weeks

A numerical statement made up of two expressions joined by an equal sign is known as an equation.. 2x - 4 = 16 is an example of an equation. We get the value of the variable x as x = 10 after solving this equation.

Coefficients, variables, operators, and constants are all components of an equation.

An equation is formed by joining two expressions with an equal sign ("=").. The two expressions on either side of the equals sign are referred to as the equation's "left-hand side" and "right-hand side" The right-hand side of an equation is usually assumed to be zero. This will not reduce generality because we can balance it by subtracting the right-hand side expression from the expressions on both sides.

The number of pages Deon reads per week should be w

The equation will be based on the question's condition, which is

Pages = 92 times in a week

Number of pages Deon reads every week = 92w

Therefore, Number of the pages Deon reads every week is 92 weeks.

Value of x = 42.5 ° and measure of angle 4 = 37.5 ° .

measure of angle 3 = measure of angle 8

( 3 x + 15 ) ° = ( x + 100 ) °

2 x = 85

x = 42.5 °

measure of angle 3 + measure of angle 4 = 180 °

measure of angle 3 = ( 3 x + 15 ) °

                                 = ( 3 * 42.5 ) + 15

Answer:

Constant of proportionality k = 7/4 if we take the proportionality relationship as ... number of minutes ∝ number of cupcakes Bor

number of minutes = k . (number of cupcakes)

Step-by-step explanation:

If a variable x is directly proportional to another variable y indicated by
x ∝ y

Then x = k.y where k is the constant of proportionality

Letting x be the number of cupcakes and y the number of minutes

number of cupcakes = k .  (number of minutes)
k = (number of minutes) / (number of cupcakes )
Here k, the constant of proportionality tells you how many many minutes it takes to ice 1 cupcake

For 40 cupcakes it takes 70 minutes. So k = 70/40 = 7/4

For 28 cupcakes it takes 49 minutes so for 1 cupcake it takes 49/28 = 7/4 so again that is the constant of proportionality

k = 7/4 given that number of minutes ∝ number of cupcakes

=>  number of minutes =  k. number of cupcakes

Note if we had x = number of cupcakes and y = number of minutes then k = 4/7 which is the number of cupcakes that can be iced in 1 minute

So one has to be careful to state what is proportional to what

10 out of 400 means P(an accident/20-24)=10/400=1/40=0.025=2.5%

If less than 5% is unlikely,  then 2.5% probability makes it unlikely a randomly selected driver in that age group would be in an accident.

No, it's not of concern if you only get concerned about likely events.  But even an unlikely event is a worthy concern to the point of attempting to drive more safely, especially when insurance for the young is already very high, and would get even higher with an accident.

Answer:

A. p - 0.25p

Step-by-step explanation:

Julie visited a craft store where all items were 25% off. She wants to program her calculator so she can input the marked price and the discounted price will be output. What is the expression for the discounted price on a marked price of p dollars?

She wants the calculator to return what the price is including the 25% discount. She will want her calculator to subtract 25%p from p so the equation will be:

p - 0.25p

option A returns what the price is including the 25% discount.

option B would return the item cost plus an additional 25%, not a discount of 25%

option C would return the marked price without the discount.

option D reflects the discount amount of 25%, not the price after the discount amount has been subtracted from the marked price.

option E tries subtract the marked price from the discount amount and would be negative.

The three different ways you can determine that an angle is a right angle are as follows:

B) You can determine whether an angle is right if it is marked with a right angle symbol.

D) You can determine whether an angle is right if the angle is a vertical pair with a right angle.

E) You can determine whether an angle is right if the angle forms a linear pair with a right angle.

A right angle can be defined as a type of angle that is formed by the intersection of two (2) straight lines at 90 degrees. This ultimately implies that, a right angle has a measure of 90 degrees.

In conclusion, we can reasonably infer and logically deduce that all right angles are marked with a right angle symbol and they are formed as a linear pair.
