Going by the rules of the game to pick a random card and then multiply it by a roll of a number cube, we can find that:

If the die is rolled, it will land on a number between 1 and 6 while there are only four cards that can be picked.

The frequency table shows that to get 28 or more, a person will have a relative frequency of:

= 1 + 2 + 1 + 1 + 1 + 1 + 1 + 1

= 9

Probability is:

= 9 / 24

= 3/8

= 37.5%

The number of products required to win 25% of the time is:

= 6

To find the winning number, count down from the highest product 6 times to get 32.

The probability of getting 36 or higher is:

= 1 / 24 + 1/24 + 1/24 + 1/24

= 1 / 6

The probability of repeating this 4 consecutive times is:

Answer:

Birds = 8

Mice = 6

Step-by-step explanation:

Conditions

Let the birds = x

Let the mice = y

Equations

x + y = 14

2x + 4y = 40

Solution

Using the top equation solve for x

x = 14 - y

Use this result to substitue for x

2(14 - y) + 4y = 40                      

Remove the brackets

28 - 2y + 4y = 40

Combine

28 + 2y = 40

Subtract 28 from both sides

28 - 28 + 2y = 40 - 28

2y = 12

Divide by 2 on both sides

2y/2 = 12/2

y = 6

Solve for x

x + y = 14

x + 6 = 14

Subtract 6 from both sides

x + 6 - 6 = 14 - 6

x = 8

Answer:

7 mice and 7 birds

Step-by-step explanation:

14 heads would mean there are 14 animals in total, as each animal has one head.

Birds have two legs, and mice have four.

2+4=6

40/6=6.67 (recurring)

6.67*2=13.3 (recurring)

6.67*4=26.67 (recurring)

Animal legs can't be in decimal numbers, so we can round the numbers.

13.3 becomes 13, 26.67 becomes 27.

13+27=40

Now we can see that there are 13 bird legs and 27 mice legs.

Divide the bird legs by 2 to get 6.5

Divide the mice legs by 4 to get 6.75

Again, we can't have a decimal of an animal, so we can round.

6.5 becomes 7, and 6.75 also becomes 7.

Therefore, there is 7 of each type of animal.

The complement of y is 110 - 8x degrees.

Complementary angles are angles that add up to 90 degrees.

Therefore,

y = 8x - 20

The complement of y can be found as follows;

complement of y = 90 - (8x - 20)

complement of y = 90 - 8x + 20

complement of y = 110 - 8x

A triangles is 2D shape with three sides and angles.

From the given diagram, the ratio of similar sides is equal to a constant as shown;

15/20 = 9+15/20+x

Cross multiply

15/9+15 = 20/20+x

15/24 = 20/20+x

Comparing with the given ratio

? = 24

X = 20+x

Find x

15(20+x) = 480

300 + 15x = 480

15x = 180

x =12

X = 20 +x

X= 32

Answer:

H (3x,3y)

Step-by-step explanation:

Dilation is a transformation when figure is enlarged or reduced by scale factor. During dilation, every point of preimage is dilated by scale factor, so it means each coordinate of that point must be multiplied by scale factor.

Hence, H(3x,3y) can be the result of dilation with scale factor of 3.

The family consumes 3 whole pizzas in total. They should order 3 whole pizzas to have enough for everyone.

To find out how many whole pizzas the Hayden family should order, we can calculate the total number of pizzas they need.

Since each person always eats 3/4 of a pizza, the total amount they eat can be calculated as follows:

3/4 + 3/4 + 3/4 + 3/4 = 4 × (3/4) = 3

So, the family consumes 3 whole pizzas in total. Therefore, they should order 3 whole pizzas to have enough for everyone.

As for the picture, imagine a circle representing a whole pizza. Divide it into four equal parts to represent each person's portion (3/4). Repeat this division three times to represent the three pizzas needed.

Answer:

obtuse because 6^2+10^2<10^2

Step-by-step explanation:

The given triangle whoe sides are 6cm, 10cm, and 12cm is an obtuse triangle and it can be determine by using pythagorian theorem, i.e. 6^2 + 10^2 < 12^2.

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a^2 + b^2 = c^2.

here, we have,

Given :

The side lengths of a triangle are: 6cm, 10cm, and 12cm.

Pythagorian theorem can be used to find out that the triangles are acute or obtuse. According to pythagorian theorem, the sum of square of shorter side is equal to the square of the third side of the right angle triangle.

According to pythagorian theorem:.

That is, H^2 = P^2 + B^2.

There are some rules to find the triangle is obtuse or acute:

If  H^2 > P^2 + B^2, than the triangle is obtuse.

If H^2 < P^2 + B^2, than the triangle is acute.

Now, applying pythagorian theorem:

we get,

6^2 + 10^2 = 12^2

136 = 144

Here, it is clearly observe that 136 <  144, i.e. 6^2 + 10^2 < 12^2 therefore, the triangle is obtuse.
