Use the pencil,plot the point (3 1/2, 2 3/4)
kipiarov [429]

Answer:

The diagram of the plotting point \left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right) is attached below.

Step-by-step explanation:

Given the points

\left(3\frac{1}{2},\:2\frac{3}{4}\right)

as

3\frac{1}{2}=\frac{7}{2}=3.5

2\frac{3}{4}=\frac{11}{4}=2.75

so the point can be visualized as:

\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)

Now, we can check the point x = 3.5, and determine the corresponding value y = 2.75 and plot the point at the location (x, y) = (3.5, 2.75)

The diagram of the plotting point \left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right) is attached below.

Fill in the missing number to make the sentence true ?/6 < 1/2
Ira Lisetskai [31]

Answer:

1 or 2

Step-by-step explanation:

1/6 < 1/2 (because 1/2 = 3/6 and 1/6 < 3/6)

2/6 < 1/2 (because 2/6 = 1/3 and if we convert these numbers to decimals, then 0.33 [2/6] < 0.5 [1/2])

The population mean annual salary for environmental compliance specialists is about ​$63 comma 500. A random sample of 31 specia
Nat2105 [25]

Answer:

0.0035289

Step-by-step explanation:

From the question;

mean annual salary = $63,500

n = sample size = 31

Standard deviation = $6,200

Firstly, we calculate the z-score of $60,500

Mathematically;

z-score = x-mean/SD/√n = (60500-63500)/6200/√(31) = -2.6941

So we want to find the probability that P(z < -2.6941)

We can get this from the standard normal table

P( z < -2.6941) = 0.0035289

How many solutions does the equation have?
SSSSS [86.1K]
Let's solve and find out.

4(2n - 4) + 3 = 8n - 19
8n - 16 + 3 = 8n - 19
8n - 13 = 8n - 19
-13 = -19

-13 and -19 are not equal, so the equation has no solutions.
