Answer:

37/200

Step-by-step explanation:

Event/Sample Space = .185 = 18.5%

Answer:

Step-by-step explanation:

If 37 people out of 200 people opened an e-mail, you can write it as 37/200.

The number above the bar is the numerator: 37

The number below the bar is the denominator: 200

Divide the numerator by the denominator to get fraction's value:

Val = 37 ÷ 200

Val = 0.185

To calculate the percent value:

0.185 =  (Calculate fraction's value.)

0.185 × 100/100 =  

(0.185 × 100)/100 =  (Multiply that number by 100.)

18.5/100 =

18.5%;  (Add the percent sign % to it.)

So that's how you get 18.5%

Answer:

2x^2+x-36=0

(4,0)

2*4^2+4-15=21

Step-by-step explanation:

The addition is one of the four fundamental mathematical operations. The two integers are 4 and 17.

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Let the two unknown integers be represented by x and y, where x

Given that The sum of two integers is 21. Therefore, we can write,

x + y = 21

y = 21 - x

Also, Fifteen less than double the square of the smaller integer is equal to the larger integer.

2(x²) - 15 = y

Substitute the value of y from the first equation,

2(x²) - 15 = 21 - x

2x² - 15 = 21 - x

2x² + x - 15 - 21 = 0

2x² + x - 36 = 0

2x² + 9x - 8x - 36 = 0

x(2x + 9) -4(2x + 9) = 0

(x-4)(2x+9) = 0

x = (-9/2), 4

Since it is given that the number are integers, therefore, the only option is 4.

Further, the two integers are,

x = 4

y = 21 - x = 21 - 4 = 17

Hence, the two integers are 4 and 17.

Answer:

is this algebra

Step-by-step explanation:

Answer:

1.)

A.) The graph does represent a proportional relationship because if you calculate the slope, it's 2/3, which is consistent throughout the line and with the given points.

Slope calculation:

[tex]\frac{y2-y1}{x2-x1} \\\\\frac{6-4}{9-6} \\\\\frac{2}{3}[/tex]

B.) The coordinate (0,0) represents that no laps have been completed nor has the time started

C.) The coordinate I chose is (6,4). It represents that 4 laps were completed in 6 minutes

2.) The values to represent a proportional relationship because once calculating the slope, which is 13, you can try it with other points. Even though there's some values missing between (6,78) and (10,130), the slope remains the same.

Slope Calculation:

[tex]\frac{y2-y1}{x2-x1} \\\\\frac{130-39}{10-3} \\\\\frac{91}{7} \\\\\frac{13}{1}[/tex]

3.)

A.) The constant of proportionality is 7/4 or 1.75

B.) y = 7/4x

4.) She'll run 8 miles because since 3/4 of an hour equates to 6 miles and there's 1/4 missing, 2 miles is 1/3 of 6 miles and 1/4 is 1/3 of 3/4 , so 1/4+1/4+1/4 = 3/4. She can run 8 miles (4*2) in 1 hour (4*1/4 hour)

41.54 mph

Step-by-step explanation:

you need to find the total distanceand total time to find the average speed

use distance/time = speed equation

time = 1.5 hours + 40 mins = 2 hours 10 mins

distance= 20 + 70 = 90 miles

90/130 mins x 60 = 41.54 mph

Answer:

We can fine x by using the pythagoras formula

a²+b² = c²

Which C is X

And

a= 17

b= 15

So

a² + b² = c²

(17)² + (15)² = c²

289 + 225 = c²

514 = c²

√514 = c

22.67 = c

So basically X is (22.671)

The missing side of the given right angled triangle is 8 units.

In the given right angled triangle, the hypotenuse side is 17 units, base is 15 units and the height is x units.

By using Pythagoras theorem, we get

17²=15²+x²

289=225+x²

x²=289-225

x²=64

x=√64

x=8 units.

Therefore, the missing side of the given right angled triangle is 8 units.

Answer:

4

Step-by-step explanation:

so 8*6=48, so we know that (4*6)+(_*6) should equal 48.

4*6=24

subtract 24 by 48 and we get 24.

now you probably know that it equals 4, but to be sure, divide 24 by 6, and you'll get 4.

3rd box: 48

Step-by-step explanation:

So, based on my knowledge, you are learning the Distributive probability. So, what the Distributive property does is it basically allows to distribute the one of the numbers in the multiplication problem. In this problem, we can see that the 8 is being distributed into two groups of 4 to make (4 * 6) + (4 * 6). Then, we solve the things in the two parenthesis, making 24 + 24. Now, all we have to do is add 24 + 24, making 48.
