(6) if y = ax + b is the least square fit line for the points (−1, 3), (0, 2), (1, 4), find a +

1 answer:

4 0

We have the following function:
y = ax + b
We evaluate two points in the function:
For (0, 2)
2 = a (0) + b
b = 2
For (1, 4)
4 = a (1) + b
4 = a + 2
a = 4-2
a = 2
Then, we have:
a + b = 2 + 2 = 4
Answer:
The result of a + b equals 4

Alenkinab [10]

Answer:

1 person

Step-by-step explanation:

It is given that a farmer wants 5 persons to complete a work of clearing his field in ten number of days.

We have to find out the number of persons required if the farmer needs to clear his field in 2 number of days.

Therefore according to the information given :

10 days = 5 persons

∴ 1 day = $\frac{5}{10}$ persons

So 2 days = $\frac{5}{10}\times 2$ persons

$=\frac{5}{5}$ person

= 1 person

A car salesperson sells a used car for $ and earns % of the sale price as commission. How many dollars does the salesperson ea

Arisa [49]

You haven't provided the $ or % that he gets, but I will attempt to use algebraic terms to explain it instead.

If the salesman sells a car for $a and gets b% of the sale price as commission, then what you need to do is divide the a by 100, then multiply it by b to find out b% of a. This will be the commission that he will earn.

a / 100 x b = commission earned in $

Edit

You've now supplied me with the $ and %, let me explain it again.

To find out the commission that he will earn, you divide 8,100 by 100 then multiply it by 9.

8,100 / 100 = 81

81 x 9 = $729 commission earned.

How many eggs are needed to make 1 dozen waffles, assuming you have enough of all other ingredients? given: 2 cups flour + 3 egg

malfutka [58]

We have been given that

2 cups flour + 3 eggs + 1 tbs oil → 4 waffles

In order to make 4 waffles we need 3 eggs.

Thus, to make 1 waffle we need 3/4 eggs.

Now, in 1 dozen there are 12 waffles. Hence, to make 12 waffles we need

$\frac{3}{4} \times 12\\
\\
=3 \times 3\\
=9$

Therefore, 9 eggs are needed to make 1 dozen waffles.

D is the correct option.
