Answer:

B slope = 1 and y intercept is 3

Step-by-step explanation:

The y intercept is where the line crosses the y axis (x is zero).

The slope can be figured by how far the line rises and runs to the next intersection of lines. In this case it goes up 1 and to the right 1. The slope would be 1/1 or 1

Answer:

Slope =1 ; Y-intercept=3

Step-by-step explanation:

The y intercept would be the point on the vertical line that touches the graph which in this case is three.

then to get to the next point that's on the line would have to move over 1 once to the right and one time up. so the slope is 1 over 1 which would equal 1.

Answer:

Irrational Number

Step-by-step explanation:

The irrational numbers are those that cannot be expressed as a ratio of two integers. Examples are as well as the square roots of many other numbers, and special numbers like e and π. It turns out that there are as many irrational numbers as rational. Irrational numbers have no exact decimal equivalents.

Step-by-step explanation:

1)

A. 2 meters to centimeters

1 m = 100 cm

[tex]2 m = 2 \times 100 \\2 m = 200 cm = 2 \times 10^2[/tex]

B)108 centimeters to meters

100 cm =1 m

[tex]1 cm = \frac{1}{100} m \\108 cm = \frac{108}{100}=108 \times 10^{-2} m[/tex]

C)2.49 meters to centimeters

1 m = 100 cm

[tex]2.49 m = 2.49 \times 100 = \frac{249}{100} \times 100 = 249 cm[/tex]

D)50 centimeters to meters

100 cm = 1m

[tex]1 cm = \frac{1}{100} m \\50 cm = \frac{50}{100}= 5 \times 10^{-1} m[/tex]

E)6.3 meters to centimeters

1 m = 100 cm

[tex]6.3 m = 6.3 \times 100=\frac{63}{10} \times 100 = 630 cm[/tex]

F)7 centimeters to meters

100 cm = 1 m

[tex]1 cm = \frac{1}{100} m\\\\7 cm = \frac{7}{100} = 7 \times 10^{-2} m[/tex]

2)

a)4 meters to millimeters

1 m = 1000 mm

[tex]4 m = 4000 = 4 \times 10^3 mm[/tex]

b)1.7 meters to millimeters

1 m = 1000 mm

[tex]1.7 m = 1.7 \times 1000= \frac{17}{10} \times 1000=17 \times 10^2 mm[/tex]

Step-by-step explanation:

Welp, I don't see the graph but I can tell you what to do. You find x = 4, and draw a vertical line up. Once your line reaches the graph, see what the y value is. If the question is nice, you should get an exact integer number

Answer:

28

Step-by-step explanation:

Answer:

50°

Step-by-step explanation:

Angle NMP is an angle that has its vertex on a point along the circumference of the circle, thus, angle NMP is referred to as an inscribed angle of the circle.

The measure of an inscribed angle is equal to half of the measure of the arc it intercepts.

Therefore, the following equation shows the relationship between inscribed angle NMP and arc NP:

m<NMP = ½ × measure of arc NP

m<NMP = ½*100

m<NMP = 50°

Answer:

The equation x + y = z relates the whole numbers.

Complete Question

The worldwide market share for a web browser was 20.5​% in a recent month. Suppose that a sample of 200 random students at a certain university finds that 50 use the browser.

At the 0.05 level of​ significance, is there evidence that the market share for the web browser at the university is greater than the worldwide market share of 20.5​%?

Answer:

The decision rule is

Fail to reject the null hypothesis

The conclusion is

There is no sufficient evidence to show that the market share for the web browser at the university is greater than the worldwide market share of  20.5 ​%?

Step-by-step explanation:

From the question we are told that

          The population proportion is  [tex]p = 0.205[/tex]

          The sample size is  n  =  200

          The number that uses the browser is  k =  50

          The level of significance is  [tex]\alpha = 0.05[/tex]

Generally the sample proportion is mathematically represented as

       [tex]\^ p = \frac{50}{200}[/tex]

=>    [tex]\^ p = 0.250[/tex]

The null hypothesis is  [tex]H_o : p = 0.205[/tex]

The  alternative hypothesis  is  [tex]H_a : p > 0.205[/tex]

Generally the test statistics is mathematically represented as

          [tex]z = \frac{ \^ p - p }{ \sqrt{ \frac{ p (1 - p )}{ n} } }[/tex]

=>       [tex]z = \frac{ 0.250 - 0.205 }{ \sqrt{ \frac{ 0.205 (1 - 0.205 )}{ 200} } }[/tex]

=>       [tex]z = 1.5764[/tex]

Generally the area under  [tex]z = 1.5764[/tex]  to the right is  

     [tex]p-value = P( Z > 1.5764 ) = 0.057467[/tex]

From the value we obtained we can see that the [tex]p-value > \alpha[/tex] hence

 The decision rule is

Fail to reject the null hypothesis

   The conclusion is

There is no sufficient evidence to show that the market share for the web browser at the university is greater than the worldwide market share of 20.5 ​%?

Answer:

29 and 35

Step-by-step explanation:

x+y=64

x-y=6

Solve by substitution.

x=6+y

6+y+y=64

6+2y=64

y=29

Then plug in 29 for y.

x+29=64 ......35

The two numbers that have a sum of 64 and a difference of 6 will be 29 and 35.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The sum of the two numbers is 64 and the difference is 6.

Let the two numbers be 'x' and 'y', and y is greater than x. Then the equations are given as,

x + y = 64           ...1

y - x = 6             ...2

Add both equations, then we have

y + y = 64 + 6

2y = 70

y = 35

Then the value of 'x' will be given as,

x + 35 = 64

x = 29

The two numbers that have a sum of 64 and a difference of 6 will be 29 and 35.

Actually Welcome to the Concept of the Statistics,

If we see here, The Andrew is working for 20 hours and his pay for 20hours is, $175

so for 1 hour, he gets = 175÷20 => $8.75 per hour

, so now after 1 year, his pay increases by $1.05 per hour, then we have to add this new amount of pay in his old amount, so that we can show that his pay is actually INCREASED, so the new pay is given as,

$8.75 + $1.05 (per hour)= $9.80

so now his total pay is given as,

E= 9.80h
