What is the y-intercept of the graph? Thank you!!

Answer:

3/7

Step-by-step explanation:

P(red) = number of red pens / total number of pens

         = 3/7

Answer:

3/7

Step-by-step explanation:

Total pens = 7

Blue pens = 4

Red pens = 3

probability of pulling out a red pen

= No of red pens / Total pens

= 3/7

Answer:

a = -1.58

Step-by-step explanation:

1/3 +a+5/4 =0

1/3+5/4= -a

4+15/12 = -a

19/12 = -a

1.58= -a

1.58/-1 = -a/-1

-1.58 = a

Answer:

37°

Step-by-step explanation:

Think of 0° as a reference point.  Then 32° is above this reference by 32 degrees, and -5° is below it by 5 degrees.  Summing up 32 and 5, we get 37.  The change in temperature was 37°

Answer:

Mrs. Lawrie forgot the 600,000 in the equation. Answer = 608,573

Step-by-step explanation:

The equation was:

600,000 + 8,000 + 500 + 70 + 3 = 608,573

Mrs. Lawrie got 68,573, while the answer was 608,573

Answer:

[tex] \boxed{ \bold{ \sf{Mean \: = 41.5}}}[/tex]

[tex] \boxed{ \bold{ \sf{Median = \: 41}}}[/tex]

Step-by-step explanation:

Given weights of the dogs :

38 , 40 , 42 , 46 , 45 , 39 , 42 , 40

Find the sum of the whole data:

sum of all items ( Σx ) = 38 + 40 + 42 + 46 + 45 + 39 + 42 + 40 = 332

Number of items ( n ) = 8

To find mean, divide the sum by the total number of data.

Finding the mean weights:

[tex] \boxed{ \sf{Mean = \: \frac{ Σx}{n}}} [/tex]

⇒[tex] \sf{ \frac{332}{8} }[/tex]

⇒[tex] \sf{41.5}[/tex]

Mean weights = 41.5

-----------------------------------------------------------------------

Finding the median

To find the median, arrange the given data in ascending order.

Given data : 38, 40 , 42 , 46 , 45 , 39 , 42 , 40

Arranging the data in ascending order :

38 , 39 , 40 , 40 , 42 , 42 , 45 , 46

Total number of observation ( n ) = 8

Finding the position of median

[tex] \boxed{ \sf{Position \: of \: median = ( \frac{n + 1}{2} ) ^{th} item}}[/tex]

⇒[tex] \sf{( \frac{8 + 1}{2} ) ^{th} item}[/tex]

⇒[tex] \sf{( \frac{9}{2} ) ^{th} item}[/tex]

⇒[tex] \sf{ {4.5}^{th} item}[/tex]

4.5 th item is the average of 4 th and 5th items .

Here, 4 th item = 40

5 th item = 42

Finding the median

[tex] \boxed{ \sf{Median = ( \frac{{4}^{th} \: item + {5}^{th} item}{2}) }}[/tex]

⇒[tex] \sf{ \frac{40 + 42}{2} }[/tex]

⇒[tex] \sf{ \frac{82}{2} }[/tex]

⇒[tex] \sf{41 }[/tex]

Hope I helped!

Best regards!!

[tex]\Huge \boxed{-2}[/tex]

Step-by-step explanation:

[tex]f(x)=-2x^2-2x+10[/tex]

For f(2), the input of the function is 2.

Let x = 2.

[tex]f(2)=-2(2)^2-2(2)+10[/tex]

Evaluate.

[tex]f(2)=-2(4)-2(2)+10[/tex]

[tex]f(2)=-8-4+10[/tex]

[tex]f(2)=-2[/tex]

Answer:

[tex]f(x) = - 2 {x}^{2} - 2x + 10[/tex]

put the value of x = 2

[tex]f(2) = - 2( {2}^{2} ) - 2(2) + 10[/tex]

[tex] f(2) = - 8 - 4 + 10[/tex]

[tex]f(2) = - 12 + 10[/tex]

[tex]f(2) = - 2[/tex]

Answer:

$799.92

Step-by-step explanation:

22.22(36)

= 799.92

So, his pay was $799.92

Answer:

5 cm.

Step-by-step explanation:

Let the lengths of the other 2 sides be 13-1 = 12  and x cm.

Then by Pythagoras:

13^2 = 12^2 + x^2

x^2 = 13^2 - 12^2

x^2 = 169 - 144 = 25

x = √25

x = 5 cm.

Step-by-step explanation:

Hey, there!!

As per your question,

There is a Right angled triangle, whose hypotenuse is 13 cm, one side is (13-1)=12 cm.

another side = ?

Let ABC be a Right angled triangle, taking angle "theta" as a refrence angle.

Hypotenuse (h)= 13 cm.

base ( b) = x

perpendicular (p)= 12cm.

By Pythagoras relation we get,

[tex]b = \sqrt{ {h}^{2} - {p}^{2} } [/tex]

[tex]b = \sqrt{ {13}^{2} - {12}^{2} } [/tex]

[tex]b = \sqrt{169 - 144} [/tex]

Therefore, base is 5 cm. Or the third side is 5 cm.

Answer:

The “1” in the quotient represents the number of tens in each of the 5 groups.

Since only 5 tens could be divided evenly among the groups, Hailey subtracted 5 from 9 to find out how many tens were left over.

Step-by-step explanation:

Given:

92÷5

Hailey's workings:

92 divided by 5.

5 goes into 9 1 time.

9 minus 5 = 4.

5 goes into 42 8 times.

42 minus 40 = 2.

The answer is 18 R 2.

The true statements about Hailey's work are:

The “1” in the quotient represents the number of tens in each of the 5 groups.

Since only 5 tens could be divided evenly among the groups, Hailey subtracted 5 from 9 to find out how many tens were left over.

Answer:

The farm planted 124,350 more cornstalks

Step-by-step explanation:

Here in this question, we want to know how much more corn stalks did a farm plant this year compared to last year.

Let’s picture it this way;

Possibly due to expansion purposes, the farm planted more cornstalks this year than last year. So to find the difference in the cornstalks planter between the two years, what needs to be done is simply to subtract the number of corn stalks planted last year from the number of corn stalks planted this year.

From the question, the number of cornstalks planted last year was 275,650 while the number of cornstalks planted this year was 400,000; So the difference between the two will be ;

400,000 - 275,650 = 124,350 cornstalks

Answer:

Step-by-step explanation:

Since ( 1 , -1) is a point on the line 2x-(2a+5)y=5 we can substitute it into the equation to find a

We have

2(1) - (-1)(2a + 5) = 5

Multiplying two negatives make a positive

That's

2 + 2a + 5 = 5

2a + 7 = 5

Group like terms

Send the constants to the right side of the equation

That's

2a = 5 - 7

2a = - 2

Divide both sides by 2

That's

We have the final answer as

Answer:

y = 6.22

You can solve this in two ways.

1.) Use SOH CAH TOA:

I typically start off by labeling the sides of the triangle with H (hypotenuse), O (opposite), and A (adjacent). Because I need to figure out what y is when given an angle and 4, I will use CAH, or cosine.

[tex] \cos(angle) = \frac{adjacent}{hypotenuse} [/tex]

[tex] \cos(50) = \frac{4}{y} [/tex]

[tex] \cos(50) \times y = 4[/tex]

[tex]y = \frac{4}{ \cos(50) } [/tex]

[tex]y = 6.22[/tex]

2.) Use Law of Sines:

Solve for the last angle inside the triangle first.

[tex]180 - (50 + 90) = 40[/tex]

Then use the angle you found (40°) in the equation.

[tex] \frac{4}{ \sin(40) } = \frac{y}{ \sin(90) } [/tex]

[tex] \frac{4}{ \sin(40) } \times \sin(90) = y[/tex]

[tex]y = 6.22[/tex]

Answer:

∠ AED = 130°

Step-by-step explanation:

CD is a straight line, thus

∠ AEC + ∠ AED = 180° , that is

50° + ∠ AED = 180° ( subtract 50° from both sides )

∠ AED = 130°

given Area is 24 and base is 8

24=1/2.8.h

24=4.h (divide 4 both of sides)

h=6 (height)

Answer:

292° 24' 36"

Step-by-step explanation:

d = int(292.41°) = 292°

m = int((292.41° - 292°) × 60) = 24'

s = (292.41° - 292° - 24'/60) × 3600 = 36"

292.41°

= 292° 24' 36"

Answer:

292 degrees 24 minutes and 36 seconds:

292° 24' 36"

Step-by-step explanation:

There are 60 minutes in a degree and 60 seconds in a minute.

so 0.41 degrees = 0.41 * 60 = 24.6 minutes

and 0.6 of a minute = 0.6 * 60 = 36 seconds.

Answer:

x = 4

Step-by-step explanation:

For this problem, we simply need to convert the words into the left hand side of the equation and solve for x:

The quantity of implies a grouping

x plus 20 is the quantity

And we want the quantity over 2 all equal to 3x:

( x + 20 ) / 2  = 3x

( x + 20 )  = 6x

20 = 5x

4 = x

And now we can check to see if x is correct by plugging back into the equation:

( x + 20 ) / 2 = 3x

( (4) + 20 ) / 2 ?= 3(4)

( 24 ) / 2 ?= 12

12 == 12

Therefore, we have shown the value of x to be equal to 4.

Cheers.
