Answer:

y=8x-29

Step-by-step explanation:

Since we know the slope (m) is 8, we can plug it in the slope-intercept formula y=mx+b, making y=8x+b.

Now we need to find the y-intercept (b). To do that, you would need to plug in the points given to you, which were (4,3).

x=4, y=3... so 3=8(4)+b

Now you can solve for the variable b to find the y-intercept.

3=8(4)+b, multiply...

3=32+b, subtract 32 on both sides...

-29=b

Therefore, the y-intercept, or b, is -29.

The equation would be y=8x-29

Biased or Unbiased:

Crazy boy [7]

Biased or Unbiased: Take 20 packages off the top of the load of packages being shipped by a truck and measure the amount of damage expected to the whole truckload.

Answer: It is a biased way of taking sample. Because the top layer of packages has less weight resting on it and may have less damage. Therefore, the given statement is biased and based on these 20 packages of the top of the load, we can not make a decision about how much damage a truckload contains.

Sarah bought 18 boxes of 65 pens at $12 a box. She sold 378 of them at 3 for $1.00 and the rest at 4 for $1.00. She sold 378 of

kodGreya [7K]

Answer:

$108

Step-by-step explanation:

The computation of the total profit is shown below:

Given that

1 box = $12

18 boxes = 12×18 = $216

Total = 18×65 = 1170 pens

Now Cost price, Cp = $216

Also,

3 = $1

So,

= 378 ÷ 3

= $126

Now

= 1170-378

= 792 pens remaining

4 = $1

So,

792

= 792 ÷ 4

= $198

Now

Total selling price, sp = 126+198 = $324

So finally

Profit = Sp - Cp

= $324 - $216

= $108

Miss Viera bought 3 1/3 pounds of bananas 2 1/2 pounds of grapes and 5.75 pounds of apples how many pounds of fruit did Ms.Viera

Semenov [28]

Answer:

11 7/12 pounds

Step-by-step explanation:

1. $\frac{10}{3} + \frac{5}{2} + \frac{23}{4}$

2. $\frac{10}{3} + \frac{5}{2} + \frac{23}{4} = \frac{40}{12} + \frac{30}{12} + \frac{69}{12}$

3. $\frac{40}{12} + \frac{30}{12} + \frac{69}{12}$

4. $\frac{139}{12}$

5. $\frac{139}{12} = 11\frac{7}{12}$

Therefore, Ms. Viera bought 11 7/12 pounds of fruit.
