Anettt [7]2 years ago

Answer:

The slope is 4, and the y-intercept is Negative five-halves

Step-by-step explanation:

This is the equation of the line in standard form

8x-2y=5

Convert the equation in slope intercept form where

y=mx+b

m is the slope b is the y-intercept

Isolate the variable y

Subtract 8x both sides

-2y = -8x+5

Divide by -2 both sides

$y=4x-\frac{5}{2}$

therefore

m=4

b= $-\frac{5}{2}$

What is the degree of vertex B and G?

Marat540 [252]

Answer:

degree of vertex B = 2

degree of vertex g = 4

Step-by-step explanation:

Using given picture we need to find about what is the degree of vertex B and G.

In graph theory, we know that the degree (or valency) of a vertex of a graph is the number of edges incident to the vertex.

So we just need to count how many edges are incindent on vertex B and G.

From picture we see that number of edges incident on vertex B = 2

Hence degree of vertex B = 2

From picture we see that number of edges incident on vertex G = 4

Hence degree of vertex g = 4

Find the median of the set of data. 30, 16, 49, 25 <br><br>

weeeeeb [17]

Answer:

16,25,30,49

25+30=55

55÷2=27.5

Step-by-step explanation:

median means the middle value of any set of data so first arrange the data into ascending order.

16, 25, 30, 49

the data is even so we take both the middle value , add it and divide it with 2

25+30=55

55÷2=27.5

(12 points and brainliest!) A group of armed forces personnel were surveyed. The branch of service was recorded in the chart bel

Rzqust [24]

Answer:

43.2 degrees

Step-by-step explanation:

1. First, find the total number of people who were surveyed.

165+135+60+130+10=500

2. Next, figure out how many the Marine Corps is out of those 500 people.

60/500= 0.12 =12%

3. Last, find out what degree the 12% would take up.

We know that a circle is 360 degrees. To find 12% of 360 degrees, you will do:

0.12*360=43.2

So, the answer is 43.2 degrees

The proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes was 0.9 −

kaheart [24]

Answer:

The proportion would be 0.1

Step-by-step explanation:

Given, the function that shows the proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes,

$f(t) = 0.9 - 0.4\ln(t)$

If t = 7 minutes,

$f(7) = 0.9 - 0.4\ln(7)=0.9 - 0.77836=0.12164\approx 0.1$

Hence, the proportion that remembered the number for 7 minutes is 0.1 ( approx )
