to test the points, substitute the x-coordinate into the equation and if the value of y equals the y-coordinate then the point lies on the graph

(0, $\frac{1}{2}$ ) → y = 0 + $\frac{3}{4}$ = $\frac{3}{4}$ ≠ $\frac{1}{2}$

(0 , $\frac{3}{4}$ ) → y = $\frac{3}{4}$ ← on graph

( $\frac{3}{4}$ , 0) → y = $\frac{3}{8}$ + $\frac{3}{4}$ ≠ 0

( $\frac{3}{4}$ , $\frac{1}{2}$ → y = $\frac{3}{8}$ + $\frac{3}{4}$ ≠ $\frac{1}{2}$

( $\frac{1}{2}$ , 1) → y = $\frac{1}{4}$ + $\frac{3}{4}$ = 1 ← on graph

the points (0, $\frac{3}{4}$ ) and ( $\frac{1}{2}$ , 1) are on the graph

How do u do percentage

lbvjy [14]

Answer:

Step-by-step explanation:

Ill try to break this down, simply:

When we talk about percentages we are talking about how much part of something we have and the percent sign is a just a symbol representing that.

Lets say we have 2 out of 10 apples and we need to convert this to a percentage

First think about how many apples we have in total... and that would be 10, and then how many apples we currently have being 2:

So if we put the part that we have over the whole thing we get:

$\frac{2}{10}$

So now lets turn this into a decimal, when its something over 10 its really easy, all we have to do is move the decimal back one place!

So we have 2 and if we move the decimal back one place we get .2 or 0.2

Now we have our decimal, to convert this into a percentage all we have to do is multiply our decimal by 100

So:

0.2 x 100 = 20%

All you do when you multiply by 100 is move the decimal back over 2 places one place for each zero so:

0.2 --> 2. --> 20.

Which gives us again 20%

Ms. drake invests $1000 at a simple interest rate of 8.5% for 2 years. how much interest will she earn in this time?

PilotLPTM [1.2K]

Ms. Drake will earn $\$ 170$ in this time from the investment of $\$ 1000$ at a simple interest with rate of interest $8.5\%$

<h3>What is the definition of simple interest?</h3>

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Conversely, for compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.

Formula for finding simple interest is $\frac{principal \times rate \ of \ interest \times time}{100}$

Given principal of Ms. Drake is $\$1000$

Rate of interest is $8.5 \%$

Time is $2$ years.

Interest $=\frac{1000 \times 8.5 \times 2}{100}$

$=\frac{17000}{100}\\=170$

Therefore, Ms. Drake will earn $\$ 170$ in this time.

A school principal wants to know more about the number of students absent each day. He counts the number of students absent each

True [87]

Answer:

6.27

Step-by-step explanation:

We are to obtain the standard deviation of the given values :

{24, 18, 31,25, 34}

The standard deviation = √(Σ(x - mean)²/ n)

The mean = (ΣX) /n

Using calculator to save computation time :

The standard deviation, s = 6.27 (2 decimal places)

Use a proportion to estimate each population. (Please solve both questions, thank you) (I’ll reward you with brainliest :)

hammer [34]

Answer:

Step-by-step explanation:

Step 1. (The capture) Capture a sample total counted =958, and them back tagged counted=38,total tagged=56

The idea is to estimate the proportion p = m/N of tagged =102.

Step 2. (The recapture) After everything has settled down, capture a new sample of n fish. Count the number of tagged fish. Suppose that k of them are tagged.

It is reasonable that, k/n would be a good estimante for p = m/N.

Accordingly, for an estimate N of N, se solve the equation m/N= k/n.
