The score for a student that spent 3.8 hours studying is expected to be 96.

Step by step solution:

The point-slope form of a linear equation is y = mx + b, where m is the slope and b the intercept with the y-axis.

To find the line that fits the data and model the relationship, we need to find the slope. Let

y = Test score

x = Study time (hours)

Two pair of coordinates from the line are (2, 60) and (3, 80):

We have m = 20, and b = 20 (intercept with the y-axis)

The equation that model the relationship is:

Second Part. Basing ourselves on the above equation, estimate the score for a student that spent 3.8 hours studying x = 3.8.

The score for a student that spent 3.8 hours studying is expected to be 96.

The length of AG=8.5 cm that is diagonal. There are four body diagonals of cuboid and twelve face diagonals. A body diagonal is referred to as the diagonal of cuboid. The diagonal of cuboid formula is √(l² + b² + h²) units.

A cuboid is a six-sided solid known as a hexahedron in geometry. Quadrilaterals make up its faces. Cuboid means "like a cube," in the sense that a cuboid can be converted into a cube by varying the length of its edges or the angles between its faces.

A diagonal in geometry is a line segment that connects two polygonal vertices when they are not on the same edge. Any sloping line is known as a diagonal informally.

A, B, C, D, E, F, G & H form a cuboid. AB= 3.2 cm, BC = 1.6 cm & CG = 7.7 cm. That is l=3.2 cm, b=1.6 cm, h=7.7 cm.

√(l² + b² + h²) units.

The nearest degree of the measure of the angle having trigonometric ratios are answered below.

The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths. They are extensively employed in all fields of geometry-related study, including geodesy, solid mechanics, celestial mechanics, and many others. Review the sine, cosine, tangent, cotangent, secant, and cosecant trigonometric ratios. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant are the six trigonometric ratios (sec). A branch of mathematics called trigonometry in geometry deals with the sides and angles of a right-angled triangle.

Considering the age of Amy and sum of their ages, Jamie is 12 years old.

Let the age of Amy be x years. Thus, the age of Jamie be (x + 5) years. Forming equation as per the age -

x + x + 5 = 19

Performing addition on Left Hand Side of the equation

2x + 5 = 19

Shifting 5 to Right Hand Side of the equation

2x = 19 - 5

Performing subtraction on Right Hand Side of the equation

2x = 14

Shifting 2 to Right Hand Side of the equation

x = 14 ÷ 2

Performing division to Right Hand Side of the equation

x = 7

The age of Amy = 7 years

The age of Jamie = 7 + 5

Performing addition

The age of Jamie = 12 years

Thus, the age of Jamie is 12 years old.

The distance between each infant's weight when they were bonded in April is the proper interpretation of the standard deviation in this situation. And the average weight was 10.20 pounds.

The variance's positive square root is the standard deviation. One of the foundational strategies in statistical analysis is standard deviation. The term "standard deviation," often shortened as "SD," tells us how far a value deviates from the mean value. It is represented by the symbol "."

Given that : The mean birth weights of infants born at an area hospital in the month of April is 128 oz. with a standard deviation of 10.2 oz.

So let's look at this and see what the correct interpretation of a standard deviation is, which is the distance between each person's actual way of being born and a braille and the main way it was, which is typically about 10 points two oh. From this, we can deduce what the question Act is. The distance between each infant's weight when they were bonded in April is the proper interpretation of the standard deviation in this situation.

Answer:

k = 1

Step-by-step explanation:

since the graph contains the point (2, 12 ) then the coordinates of the point make the equation true.

substitute x = 2 and f(x) = 12 into the equation and solve for k

12 = k(2)³ + 2² - k(2) + 2 , that is

12 = 8k + 4 - 2k + 2

12 = 6k + 6 ( subtract 6 from both sides )

6 = 6k ( divide both sides by 6 )

1 = k

The coordinates of the image of polygon A'B'C'D' after a translation of 4 units down and 5 units right would be A' (-1, 1), B' (-1, -2), C' (3, -2), D' (3, 2).

In Geometry, the translation of a geometric figure to the right simply means subtracting a digit from the value on the x-coordinate (x-axis) of the pre-image and translating a geometric figure down simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image.

By translating the pre-image of polygon ABCD vertically down 4 units and horizontally right 5 units, the coordinates of the image of polygon A'B'C'D' include the following:

(x, y)                               →                  (x + 5, y - 4)

Coordinate A = (-6, 5)   →    Coordinate A' (-6 + 5, 5 - 4) = (-1, 1)

Coordinate B = (-6, 2)   →    Coordinate B' = (-6 + 5, 2 - 4) = (-1, -2)

Coordinate C = (-2, 2)   →     Coordinate C' = (-2 + 5, 2 - 4) = (3, -2)

Answer:

Answer:

6.5 × 10^9 kg

Step-by-step explanation:

Here is the answer to the question the way it is asked, but the question is ridiculous. 1 kernel of popcorn has a mass of perhaps 1.5 g, so 1.25 g is reasonable. That means 1 kernel has a mass of 0.00125 kg, or 1.25 × 10^-3 kg. To state that 1 kernel of popcorn has a mass of 1.25 × 10^1 means that a kernel of popcorn has a mass of 12.5 kg which corresponds to a weight of approximately 27.6 lb. That is just ridiculous.

Using the ridiculous information given in the problem, then if 1 kernel has a mass of 1.25 × 10^1 kg, then 5.2 × 10^8 kernels have a mass of

(1.25 × 10^1 kg) × (5.2 × 10^8) =

= (1.25 × 5.2) × (10^1 × 10^8) kg

= 6.5 × 10^9 kg

A kite contains four inner angles, which add up to 360 degrees. It has one pair of equal and opposite obtuse angles in each of these angles.

Answer:

∠D = 94°

Step-by-step explanation:

A kite is a quadrilateral.  

Therefore, the sum of its interior angles is 360°.

⇒ ∠A + ∠B + ∠C + ∠D = 360°

⇒ 108° + ∠B + 64° + ∠D = 360°

⇒ 172° + ∠B + ∠D = 360°

⇒ ∠B + ∠D = 188°

A kite has one pair of opposite (obtuse) angles that are equal.

Therefore, ∠D = ∠B.

⇒ ∠B + ∠D = 188°

⇒ ∠D + ∠D = 188°

⇒ 2∠D = 188°

⇒ ∠D = 94°

If Ellen's dog has a pen that is [tex]3^{2}[/tex] feet by [tex]3^{3}[/tex] feet, then the area of the dog pen is 243 square feet

Here the Ellen's dog pen is in rectangular shape

The area of the rectangle = l × w

Where l is the length of the rectangle

w is the width of the rectangle

In this question

The length of the rectangle =  [tex]3^{2}[/tex] feet

= 3×3

= 9 feet

The width of the rectangle =  [tex]3^{3}[/tex] feet

The likelihood or probability that she will give the first student a blue calculator and the second student a yellow calculator is 6.6%.

The math teacher Mrs. Piatt has six black, nine yellow, and two blue calculators.

Therefore, the total number of calculators is 17.

The probability that she hands out a blue calculator to the first student is:

P₁ = Number of blue calculators/ Total number of calculator

P₁ = 2/17

Now, as a calculator is handed out to a student. Then the remaining number of calculators is 16.

Therefore, the probability that the second student gets a yellow calculator will:

P₂ = Number of yellow calculators/ Total number of calculators.

P₂ = 9/16

Therefore, the probability that she will hand out a blue calculator to the first student, then hand out a yellow calculator second will be:
