Answer:

-3/2.

Step-by-step explanation:

When x is 4 , y is 9. When x is 8, y is 3. Therefore, you do the change in y/change in x to find the average rate. 3-9/8-4. This is equal to -3/2.

After seeing countless commercials claiming one can get cheaper car insurance from an online company, a local insurance agent wa

Answer:

Null Hypothesis, $H_0$ : $\mu_d$ = 0

Alternate Hypothesis, $\mu_d\neq$ 0

Step-by-step explanation:

We are given that a local insurance agent randomly selected profiles for 10 of his clients and checked online price quotes for their policies.

Then, based on paired data on the 10 clients (the price he offered them and the corresponding online quote), he obtained t-statistic = 0.709 p-value = 0.248.

Here , we will use the concept of Paired data test statistics because the prices that the local insurance agent offered and the corresponding online quotes are from the same single data. These information has not been taken from the two independent samples.

So, Null Hypothesis, $H_0$ : $\mu_d$ = 0

Alternate Hypothesis, $\mu_d\neq$ 0

Here, null hypothesis states that there is no difference between the price he offered them and the corresponding online quote.

On the other hand, alternate hypothesis states that there is difference between the price he offered them and the corresponding online quote.

Hence, this would be the correct null and alternative hypothesis.

A granola recipe calls for 2 1/3 (mixed number 2 and 1/3) cups of almonds. A bag of almonds contains 2 cups. To make 2 1/2 (mixe

marta [7]

Answer:

4 1/6 cups of almonds left

Step-by-step explanation:

Granola recipe = 2 1/3 cups of almonds

2 1/2 batches of granola = 2 1/3 cups of almonds × 2 1/2

= 2 1/3 × 2 1/2

= 7/3 × 5/2

= (7*5)/(3*2)

= 35/6

= 5 5/6 cups of almonds

A bag of almonds = 2 cups

5 bags of almonds = 10 cups

Cups of almonds left = 10 cups - 35/6 cups

= 60-35/6

= 25/6

= 4 1/6 cups

Answer:

y=5x+1

Step-by-step explanation:

If you look closely at each side, you will see that the x increases by one and the y increases by five.

To get to zero (0) from one (1), you need to substract one.

Every time one is subtracted for x, 5 is subtracted from y.

6-5=1

Hope this helps :-)
