Answer:

The second set.

Step-by-step explanation:

Consider the first set of ordered pairs.

For an increase of 9 is the x-values the y values increases by 1.

In the case of the second set the increase in y values compared with increase in y values is different:

x = 2-0 = 2, y = 10- 0 = 10. That is 5 units of y  for every unit of x.

x = 5-2 = 3, y = 13-10 = 3. That is 1 unit of y for every 1 unit of x.

Serhud [2]

Answer:

13/24

Step-by-step explanation:

Find the LCD of 8 and 3, which is 24.

Now, multiply both numerators so that the following fractions would be equal:

7/8 = x/24

1/3 = y/24

Our result is that

7/8=21/24

1/3 = 8/24

21/24 - 8/24 = 13/24

I really need help on this
viktelen [127]

Answer:

A)  sarah = $ 937.33  ; claire = $928.00

Step-by-step explanation:

<h2><u>Sarah - Compound interest </u></h2>

compund interest formula :

A = P ( 1 + r/100) ^ n

A is the amount invested

P is the principle

r is the rate of interest

n is the number of years

A = 800 * ( 1 + 2 /100) ^8

=937.33

Sarah has $ 937.33

<h2><u>Claire - Simple interest </u></h2>

simple interest formula :

= PRT / 100

P is the principle

R is the rate

T is the number of years

= 800*2*8 /100

=128

128 + 800 = 928

claire has $ 928

And an 11 ounce bag of rice noodles makes 10 servings at that rate find how many ounces of noodles I needed for 19 servings to t
nikdorinn [45]

Answer:

20.9 ounces of rice noodles are required to make 19 servings.                    

Step-by-step explanation:

We are given the following in the question:

11 ounce bag = 10 servings

Ration of ounces of rice noodles to servings is:

\dfrac{\text{Weight of rice noodles}}{\text{Serivings}} = \dfrac{11}{10} = 1.1

We have to find ounces of noodles are needed for 19 servings.

Thus, we can write:

\dfrac{\text{Weight of rice noodles}}{19} = 1.1\\\\\Rightarrow \text{Weight of rice noodles} = 1.1\times 19\\\Rightarrow \text{Weight of rice noodles} =20.9\text{ ounces}

Thus, 20.9 ounces of rice noodles are required to make 19 servings.

6. 1 point Mark only one oval. Not biased Bias 7. 2 points Mark only one oval. 26 oz 27 oz 28 oz A town has 15,000 registered vo
ValentinkaMS [17]

Answer:

About 7,500 registered voters are expected to vote for the new dog park.

Step-by-step explanation:

- A town has 15,000 registered voters.

- A random sample of 200 voters shows that 100 voters are in favour of a new dog park.

How many registered voters are likely to vote for the dog park?

The laws of probability allows us to extrapolate and use the proportion of randomly sampled registered voters that vote for a new dog park to calculate the actual number of registered voters that will vote for a new dog park.

Proportion of randomly sampled registered voters that voted for a new dog park

= (100/200) = 0.50

Proportion of overall registered voters that will vote for a new dog park will also be 0.50.

Number of likely registers voters that'll vote for a new dog park = 0.50 × 15,000 = 7,500

Hope this Helps!!!
