Graph The Line: Y=2x+1
Answer 2

Answer:

I can tell you how to graph it by following my steps

Step-by-step explanation:

The equation y=2x+1 gives u the following information:

The slope is 2/1

The line intercepts 1 on the y axis

First, I would put a point or a dot on (0,1) on the y axis. Then I would then start making 2 points above and below my original point. I would do this by using the sope 2/1. By using my slope I know that (1,3) and (-1,-1). I would then put points on (1,3) and (-1,-1). Finally, I will grab my ruler and draw a line connecting all my points together.

Hope this was not confusing. I tried to make sense lol.

Can someone please help me figure out how to solve this?

Answers

Answer:

B. 48m²

Step-by-step explanation:

The formula for volume is length (base) times width times height, or LWH. If you break the shape into three separate areas, you can figure out the volume for each part and then add it up.

The large part on the bottom is 7m long, 2m across. Since we know the entire shape is 4m tall and the indent is 2m deep, we know that the height for the bottom part will also be 2m. 7 · 2 · 2 = 28.

The block on the left is 2m tall, 2m across, and its width is also 2m as shown by the measurement on the bottom-right. 2 · 2 · 2 = 8.

Finally, the block on the right is 2m tall, 3m across, with a width of 2m. 3 · 2 · 2 = 12. And when you add it all up, 28 + 8 + 12 = 48. Hope this helps! Feel free to ask any questions!

Use the given line of best fit to approximate the rate of change relative to the scatter plot below.

A. 1/20 errors per word translated

B. 1/5 errors per word translated

C. 1/10 errors per word translated

D. 3/20 errors per word translated

Answers

Answer:

C. 1/10 errors per word translated

Step-by-step explanation:

According to this graph, we can see that every 100 words-translated, there are about 10 errors (red line). The red line continues at this slope/ratio, and so it would be 10/100 or 1/10 simplified.

The rate of change relative to the scatter plot below will be 1/10 errors per word translated. Option C is correct.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

For the given condition, we have to find the rate of change relative to the scatters plot below.

The given graph is in between the total error and the translation error. This graph shows that there are around 10 translation mistakes for every 100 words (red line). Given that the red line continues at this slope and ratio, it would be expressed as 10/100 or 1/10.

Thus, the rate of change relative to the scatter plot below will be 1/10 errors per word translated. Option C is correct.

Find all roots of the polynomial function f(x) = 2x^4-x^3-13x^2+5x+15

Answers

Answer:

Roots are :  1, -7 and -7

Step-by-step explanation:

When we put x = -1 in F(x) it is equal to 0

Thus, (x + 1) is factor of given function.

When we divide F(x) by (x + 1) it gives the value (x² - 6x - 7)

factorizing the work  x² - 6x - 7 by middle term splitting.

> x² - 6x - 7 = x² - 7x + x - 7

>  x(x - 7) + 1(x - 7)

>  (x + 1) (x - 7)

then,  x³ - 5x² - 13x - 7 = (x + 1)(x + 1)(x - 7)

x = -1, -1, 7 the factor.

there are 6 boys and 5 girls in the debate class. kids are being selected to go present their work without getting opt-out where is the probability that a boy will be selected to present twice?

Answers

Answer:

30%?

Step-by-step explanation:

6 boys, 5 girls

first selection is a 6/11 chance it's a boy.

second seletion is a 6/11 chance it's a boy.

6/11 times 6/11 is... 0.2975 or about a 30% chance ( i think)

Just multiply the probability of the first event by the second. For example, if the probability of event A is 2/9 and the probability of event B is 3/9 then the probability of both events happening at the same time is (2/9)*(3/9) = 6/81 = 2/27.

George is 31 years older than Leo who is 15 years younger than Carol. In how many years will Carol be the same age as George is now?

Answers

In 16 years Carol will be the same age as George.

Answer:

16 years

Step-by-step explanation:

Break the problem down:

George = 31 + Leo

Leo = Carol - 15

Carol = ?

The problem is asking for the number of years it will take for Carol to be George's current age.

Leo is 15 years younger than Carol which means Carol is 15 years older than Leo.

George is 31 years older than Leo. Carol is older than Leo by 15 years.

This means we have to find the difference between 31 and 15.

31 - 15 = 16

Since the difference between George and Carol's age is 16 years, it will take Carol 16 years to be the same age as George is now.
