Answer:

Sally's room is 61 square feet bigger than Georgia's room

Step-by-step explanation:

Sally's room's area: 881.5 square feet

21.5 x 41 = 881.5

Georgia's room's area: 820.5 square feet

(21.5 x 41) - 56 = 820.5

881.5 - 820.5 = 61

Answer:

64π^2  cubic inches

Step-by-step explanation:

The question is not complete, the shapes are not given

Diameter of base= 16π

Radius of base= 8π

Height of cylinder = 8 inches

Let us find the volume of the cylinder

V= πr^2h

V= π* (8π)* 8

V= 64π^2  cubic inches

Hence the volume of the cylinder is 64π^2  cubic inches

Answer:

x^4-3x^3+x^2-4

mrk me brainliest plz

Step-by-step explanation:

Given the following functions

R(x) = 2x^4 – 3x^3 + 2x – 1 and

C(x) = x^4 – x^2 + 2x + 3

We are to find the profit function P(x)

P(x) = R(x) - C(x)

P(x) = 2x^4 – 3x^3 + 2x – 1 - ( x^4 – x^2 + 2x + 3)

P(x) = 2x^4 – 3x^3 + 2x – 1 - x^4 + x^2 - 2x - 3

Collect the like terms

P(x) = 2x^4-x^4-3x^3+x^2+2x-2x-1-3

P(x) = x^4-3x^3+x^2+0-4

P(x) = x^4-3x^3+x^2-4

Hence the required profit function P(x) is x^4-3x^3+x^2-4

Answer:

Answer:

Option C

{ - ⁵/₃ , ³/₂ }

Step-by-step explanation:

6x² + x - 15 = 0

6x² + 10x - 9x - 15 = 0

2x(3x + 5) - 3(3x + 5) = 0

(2x - 3) (3x + 5) = 0

2x - 3 = 0 or 3x + 5 = 0

x = ³/₂ or x = - ⁵/₃

Thus, The answer is { - ⁵/₃ , ³/₂ }

Answer:

Line B

Step-by-step explanation:

Line B is the correct answer because the black dots (which represent data) correlate with Line B

Answer:

Line B is the line of best fit.

Step-by-step explanation:

The line of best fit helps in a scatterplot by giving the average of whatever the plot is about. So, the line HAS to go through most (if not all) the areas of the plotted points. In the example above, the line is between the maximum and the minimum points, making this line the best fit.

Answer:

D.) I would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be smaller than in Test A.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

By the Central Limit Theorem:

Both tests, A and B, are of the same quantity, so they have the same mean and standard deviation. However, since the standard error is inversely proportional to the sample size, and test B has a greater sample size than test A, the standard error in test B should be lower, and thus, the correct answer is given by option D.

Answer:

x=72

Step-by-step explanation:

180-36=144 (180 degrees in a triangle)

144/2=72

In the isosceles triangle having one angle is 36° and rest two equal angles are x then the value of x is, 72°

Any triangle with any two sides that have the same length is known as an isosceles triangle. An isosceles triangle has two angles that are equal in size and opposed to its equal sides.

In an isosceles triangle, the two equal angles are congruent, so we can call one of them "x". The sum of the angles in a triangle is 180°, so we can set up an equation to solve for x:

x + x + 36° = 180°

Simplifying the equation:

2x + 36° = 180°

Subtracting 36 from both sides:

2x = 144°

Dividing both sides by 2:

x = 72°

So, the value of x is 72°.

Answer:

C

Step-by-step explanation:

P= side 1+ side 2 + side 3

40-(17+8)=15

15x8/2=60

Area of triangle, who has perimeter of 40 centimeters is 60 cm².

Area of a Triangle = A = ½ (b × h) square units

where b and h are the base and height of the triangle, respectively.

Given: Perimeter= 40cm

Now, 17+8+side=40

               side= 40-25

                side= 15 cm

Now, Area of triangle,

=1/2*b*h

= 0.5*15*8

= 60 cm²

Hence,  Area of triangle= 60 cm².

Answer:

option a and b are the correct option

Answer:0.75

Step-by-step explanation:12 is half of 24

Answer should be be half of 1.5

Answer:

Step-by-step explanation:

you know some things about the two angles they are the complimentary parts of just one of those perpendicular lines.   so you can say

180 = (6x + 5) + (3x+13)

180 = 9x +18

162 = 9x

18 = x

Answer:

Solution given;

6x+5+3x+13=180(sum of exterior angle is 180°)

9x=180-18

x=162/9

x=18 is a required answer.
