A fourth album has a mean length of 8 minutes with a mean absolute deviation of 1.2. Is this data set very different from each of the others?

Answer:

228.75 inches cubed

Step-by-step explanation:

This is because the formula to find the volume of a rectangular prism is base x height x width. so if you plug in the numbers, 7 5/8 x 12 x 2 1/2, and we get our answer of 228.75 inches cubed or 228.75 in.^3

Answer:

They both are a 90 degree angle.

For the parallelogram KLMN, opposite angles K and M are equal.

Parallelogram are type of quadrilateral in two dimensional geometry which has four sides, four vertices and four angles where opposite sides are equal. They also have the two pairs of sides parallel to each other. These sides are opposite sides.

The sum of the adjacent angles of the parallelogram is equal to 180 degrees and the sum of all angles is equal to 360 degrees. Also the opposite angles are equal.

Given that KLMN is a parallelogram.

Here K and M are opposite vertices and also L and N are opposite vertices.

In a parallelogram, we know that measure of opposite angles will be equal. So here, measure of angles K and M are equal.

Therefore, since angles K and M are opposite angles of the parallelogram, they are equal.

Answer:

8. Scalene 9. Isosceles

Step-by-step explanation:

8) Acute Scalene

9) Right Isosceles

Triangles can be classified in 3 ways based on their angles: acute, obtuse, and right. There are 3 ways to classify based on sides: scalene, isosceles, and equilateral.

Definitions

Acute - a triangle with 3 acute angles (angles under 90 degrees)

Obtuse - a triangle with 1 obtuse angle (angle greater than 90 degrees)

Right - a triangle with 1 right angle (90-degree angle)

Scalene - a triangle with sides of all different lengths

Isosceles - a triangle with 2 equal sides and angles

Equilateral - a triangle with 3 equal sides

Question 8

From the 2 angles we are given, we can tell that all of the angles are different. This must mean that the sides are also different. Since the sides are different, this must be a scalene triangle. Additionally, the missing angle is 100 degrees; thus, it must be an obtuse triangle.

Question 9

The marks on the 2 sides mean that these lines are equal. Therefore, it must be an isosceles triangle. One of the angles is marked with a box. This means that the angle is 90 degrees.  So, it is a right triangle.

i cant process what your saying

Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

Answer: 30° - 3d ≤ 20°

Step-by-step explanation:

Here the constant rate of decreasing the temperature = d degree,

Thus, the total decreasing in three days = 3d degree,

If the temperature on Monday = 30°

Then the temperature n Thursday =  30° - 3d

Since, The swimming pool is open when the high temperature is higher than 20°

⇒ 30° - 3d ≤ 20°

Which is the required inequality to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.

To find the quadrent a coordinate pair is in:

1. look at the "x" value in the (x,y) pair

2. if its negetive go leftward and if its positive go rightward

3. once you have moved to the respective x location do the same thing with the y coordinate in the (x,y) pair

4. up is positive for y and down is negitive.

for example (3,3) would be 3 to the right and 3 up so its in the top right quadrent

(-3,-3) would be 3 left and 3 down so its in the bottom left

Remark

The plan is to find the third side. It and the 9 foot side form a right angle. The base is given as 9 feet. The third sid will be the altitutude. The formula is Area = 1/2 * Base * third side.

Formulas

c^2 = b^2 + a^2

Area = 1/2 b * a

Givens

c = 13 feet

a = ?

b = 9 feet.

Answer: 42.2 square feet.

Solution

c^2 = b^2 + a^2

13^2 = 9^2 + a^2

169 = 81 + a^2                 Subtract 81 from both sides.

169 - 81 =81 - 81 + a^2    Combine

88 = a^2                          Take the square root of both sides

√a^2=√88

a = 9.381

Area = 1/2 * 9 * 9.381

Area = 42.21

Rounded to the nearest 1/10 Area = 42.2

c = 0.06p + p

Step-by-step explanation:

hope this helped

An equation that represents the total cost, c, of any item bought in Idaho whose price is p is c = 1.06p.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

Cost of the winter jacket = $30

Sales tax = 6%

Total cost of the winter jacket = 30 + (6% × 30)

                                                   = 30 + 1.8

                                                   = $31.8

If the total cost of any item is c whose price is p,

c = p + (6% × p)

c = p + 0.06p

c = 1.06p

Hence the required equation is c = 1.06p.

Answer:

B and C

Step-by-step explanation:

Kitten:

2 times in the morning and 2 times in the evening = 4 times per day

That means Ariane feeds her kitten 4k grams of food per day.

Dog:

1 time in the morning and 1 time in the evening = 2 times per day

That means Ariane feeds her dog 2d grams of food per day.

Answer:

If you find the total, you have to add the kitten's food per day and the dog's food per day. That is 4k + 2d, which is the same as choice B.

We can break 4k into 2k + 2k. We can also break 2d into d + d. We can write that as 2k + 2k + d + d. That equals the same as choice C, making it a correct choice.

Samantha's percent error is 15.24%.

The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.

Given:

Samantha guessed there were 295 jelly beans.

There were actually 250 jelly beans in the jar.

So, the percent error

= (295- 250) / 295 x 100

= 45 / 295 x 100

= 0.15254 x 100

= 15.24 %

Answer:

The average change in temperature per hour was -8°F.

Step-by-step explanation:

Using the equation 48-(-16) we know that the temperature dropped by 64°F.

[tex]48-(-16)=64[/tex]

We now know that the temperature dropped by 64°F in a period of 8 hours. Using the equation -64/8 we can find the average change in temperature per hour.
