We can use the points (1, 4) and (4, 9) to solve.

Slope formula: y2-y1/x2-x1

= 9-4/4-1

= 5/3 or 1 2/3

Best of Luck!

An experimenter is randomly sampling 4 objects in order from among 43 objects. What is the total number of samples in the sample
Ivenika [448]

Answer:

10.75

Step-by-step explanation:

First you see how many times 4 can go into 4 in the tens place which is 1 .You multiply 4 times 1and you get 4 .Then you minus 4 from 4 and get

Then you bring down the 3 and see how many times 4 can go into 3 which is 0 .So you put a decimal point and bring down a 0.

See how many times 4 can go into 30,which will be 7 times.After , you multiply 7 times 4 and you get 28.Subtract 29 from 30 and you get 20.You bring down the 0 .

See how many times 4 can go into 20 which is 5.Mutiply 5 times 4 and get 20 then subtract 20 from 20.

Get a final quotient of 10.75.

Whats the first operation needed to solve x/3-3=11
velikii [3]

Hello!

To solve algebraic equation, we will need to use the acronym SADMEP.

SADMEP is similar to PEMDAS, but it is strictly used for solving algebraic equations. Expanded, it is subtract, addition, division, multiplication, exponents, and then parentheses.

Looking at SADMEP, we see that subtract/addition comes first, then division/multiplication, and then exponents/parentheses.

In our equation, our goal is to isolate the variable, "x". Since we have two constants, -3 and 11, and -3 is on the side with the variable, we can add -3 to both sides of the equation first.

Therefore, the first operation needed to solve the equation is addition.

Question 2 Find the slope between the two points: (3, 20) and (5.8)​
GuDViN [60]

Answer:

The slope between the two points: (3, 20) and (5, 8) is -6.​

Step-by-step explanation:

Put the points in the slope formula:

m = (y₂ - y₁)/(x₂ - x₁)

Substitute the values.

m = (8 - 20)/(5 - 3)

Subtract.

m = (-12)/2

Divide.

m = -6

a savings account receives 12% simple interest p.a. how long would it take for £30000 to gain £28800 in interest
Elis [28]

Answer:

<h2>8 years</h2>

Step-by-step explanation:

Given,

Principal (P) = £ 30000

Simple Interest ( I ) = £ 28800

Rate (R) = 12%

Time (t) = ?

Now,

t =  \frac{i \times 100}{p \:  \times  \: r}

=  \frac{28800 \times 100}{30000 \times 12}

=  \frac{2880000}{360000}

= 8 \: years

Hence, It would take 8 years.

Hope this helps...

Good luck on your assignment...
