Math help What are the solutions​

Answer:

0.5

Step-by-step explanation:

the sum of the probabilities of the outcome should equal 1

Probability the outcome is not A = sum of probabilities of the outcome - probability the outcome is A

1 - 0.5 = 0.5

Answer:

17. See below

18. 750

Step-by-step explanation:

17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.

18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:

[tex]y=0.5x+125[/tex]

Now, if they need 500 dollars, y is thus equal to 500 dollars. Solving the equation:

[tex]500=0.5x+125[/tex]

[tex]500-125=0.5x[/tex]

[tex]375=0.5x[/tex]

[tex]\frac{375}{0.5} =x[/tex]

[tex]375*2=x[/tex]

[tex]750=x[/tex]

Thus, 750 lollipops must be sold.

Answer

Correct option is

D

all of the above

For any two rational numbers a and b,  

(a+b),(a−b),(b−a) & (a×b) are all rational numbers.

Thus, rational numbers are closed under addition, subtraction and multiplication. (for the first one)

Answer:

Step-by-step explanation:

X+Y or 5+7=12

A rational number is any number that can be divided without going on and on forever. (for the 2nd one )

Answer:

(-5/4, 1/2)

Step-by-step explanation:

x = -5/4, y = 1/2

Answer: 56

Step-by-step explanation:

Since we are informed that Isaac’s dad built a shelf for his video games that is 42 inches wide and that each video game is 6/8 inches wide.

The number of video games that Isaac can fit on the shelf will be gotten by dividing the length of the shelf by the width of each video game. This will be:

= 42 ÷ 6/8

= 42 × 8/6

= 56

Therefore, Isaac can fit 56 video games on the shelf.

Answer:

Indian system of numeration:

With the Indian system, when writing a million, a comma comes after the first three digits and then after 2 digits from thenceforth.

For instance, a million would be:

= 10,00,000

Distance to moon in Indian numeration = 3,84,014 km

International System of Numeration:

Here a comma separates a maximum of 3 digits. A million here would be:

= 1,000,000

Distance to moon is therefore:

= 384,014 km

Answer:

d = 25.12

Step-by-step explanation:

Answer:

I’m not sure :/

Step-by-step explanation:

Answer:

To find the perimeter of a polygon, you just have to add the values of each side.

For example, if a rectangle has a length of 10 inches and a width of 5 inches, you would add, 10 + 10 + 5 + 5, which is equal to 30. This is found because the length of one side is 10, the other is also 10, and the width is 5, and the other is also 5.

Answer:

90 km/h

Step-by-step explanation:

To solve this problem you first need to convert minutes to hours since the unit is km/h. Doing this we get half an hour (1 hour=60 mins so you divide 30 by 60) after converting you simply divide 45 by 1/2 or .5 to get the answer.

Answer:

900

Step-by-step explanation:

First, we set up our equation: To find the area of a trapaziod, the equation is Base 1+ Base 2 times Height

So, the equation would be: A=26+46x19

A=72x19

72 times 19= 900

Hope this helps and have a nice day!

Answer:

height (h) = 15

Step-by-step explanation:

To figure this out, we use the formula 2 · [tex]\frac{A}{a + b}[/tex], where "A" is the area, "a" is one base measure, and "b" is the other base measure.

After plugging in the numbers into the formula, we get 2 · [tex]\frac{390}{23 + 29}[/tex], which equals 15.

Answer:

18.326 inches

Step-by-step explanation:

The question is basically asking us to find the arc length that the tip of the minute hand travels. The formula for an arc length is S=θr. So we need th find the angle that the minute hand passes through. We know that there is 360 degrees in a cicle and there is 12 stops around a clock, so divide 360 by 12 to find the degrees the minute hand travels every 5 minutes. We ge that every 5 minutes the hand travels 30 degrees, and 35 minutes is 7*5 so we multiple 30*7 to find the angular displacement, and we get 210 degrees. This equation uses radians though so we have to convert, which can be done doing [tex]\frac{210}{1} *\frac{\pi }{180}[/tex], and we ge that θ is [tex]\frac{7\pi }{6}[/tex] so ([tex]\frac{7\pi }{6}[/tex])(5)= 18.326 inches
