Answer:

Step-by-step explanation:

Answer: TRUE

Step-by-step explanation:

The smallest number of coins you could have had before finding the bag of 53 coins is 371. which is more than 200.

There are seven bags, so there are 7x coins in total:

7x = T.

Since the number of coins in each bag must be an integer, (T + 53) must be a multiple of 8. We know that T = 7x, so we can write this as follows:

(7x + 53) ≡ 0

(mod 8)This means that 7x ≡ 3 (mod 8).

The solutions to this congruence are

x ≡ 3, 11 (mod 8).

Since x is a positive integer, we take

x = 11

(the other possibility, x = 3,

leads to a smaller value for T).

Therefore, T = 7x = 77, and the total number of coins after the bag of 53 coins is found is

T + 53 = 130.

After redistributing the coins into eight equal bags, each bag contains 16 coins.

Therefore, the number of coins you had initially was

7x = 77,

so the smallest number of coins you could have had before finding the bag of 53 coins is

77 - 53 = 24.

After redistributing the coins, you had

8 × 16 = 128 coins left,

Answer:

1/4 * 1/2 = 1/8

Step-by-step explanation:

1/4 chance of choosing an 'm'

1/2 chance of getting tails

Probability of both events = 1/4 * 1/2 = 1/8

Therefore, probability solution is estimating this likelihood without additional data or analysis is inappropriate correct response is option a.

The main goal of the mathematical branch known as statistical inference is to estimate the likelihood that a statement is accurate or that a particular event will take place. Any number among 0 and 1, where 1 typically denotes confidence and 0 typically denotes possibility, can be used to symbolise chance. A probability diagram illustrates the likelihood that a particular occurrence will take place.

Here,

Because of the skewed demographic distribution, the right response is (a).

We could use the normally distributed to compute probabilities because the length of adult American ladybirds is distributed normally with a known standard deviation. The normal distribution may not, however, correctly depict the distribution of ladybird lengths in the population due to the skewed population distribution.

Furthermore, even if the difference between the actual community mean and the assumed mean of 1 cm is tiny, the given size of the population of 440000 could result in a statistically significant outcome.

However, because the assumption of normality may not hold true, this does not imply that we can accurately determine the likelihood of a random ladybird in Raleigh being larger than 1.5 centimetres.

Therefore, estimating this likelihood without additional data or analysis is inappropriate.

Answer:

  24 square units

Step-by-step explanation:

There are a couple of ways you can figure the area of the frame:

__

The dimensions of the outer rectangle are twice the frame width plus the dimensions of the inner rectangle. That makes them 8 wide by 6 high. Then the difference of areas is ...

  A = (8)(6) -(6)(4) = 48 -24 = 24 . . . . square units frame area

__

The centerline of the frame is a rectangle with 1 unit greater length and width than the inner rectangle. It is 7 units by 5 units, so will have a perimeter of ...

  P = 2(L+W) = 2(7+5) = 24 . . . . units

Then the area of the frame is this length multiplied by the width of the frame:

  A = (24)(1) = 24 . . . . square units frame area

To evaluate the integral ∫√√x⋅(13x) dx, we can make a substitution u = √x. Then, du/dx = 1/(2√x) and dx = 2u du.

Making the substitution, the integral becomes:

∫(√u)⋅(13u²)⋅(2u du)

Simplifying, we have:

26∫u^3/2 du

Integrating term by term, we add 1 to the exponent and divide by the new exponent:

26 * [(u^(3/2 + 1))/(3/2 + 1)] + C

= 26 * [(u^(5/2))/(5/2)] + C

= (52/5) * u^(5/2) + C

Now, substituting back u = √x, we have:

(52/5) * (√x)^(5/2) + C

= (52/5) * (x^(1/4)) + C

So, the evaluated integral is (52/5) * (x^(1/4)) + C.

To check our result, we can differentiate the obtained expression and verify if it matches the original integrand.

Differentiating (52/5) * (x^(1/4)) + C with respect to x, we get:

d/dx [(52/5) * (x^(1/4))] + d/dx [C]

= (52/5) * (1/4) * x^(-3/4)

= 13 * x^(-3/4)

The result matches the original integrand, confirming the correctness of our evaluation.

Option (d)- No, because the events are not independent. Hence we can not conclude that because (0.26)(0.15) = 0.039 about 4% of the labor force are college-educated labors or operators.

We have given that government data show that 26% of the civilian labor force has at least 4 years of college and that 15% of the labor force works as laborers or operators of machine or vehicle.

So here,

The surface area of the sphere is about 50.27 square feet.

The formula for the surface area of a sphere is:

Surface area = 4πr²

The circumference of the sphere as C = 4r ft.

The radius of the sphere as follows:

C = 2πr

4r = 2πr

r = 2 ft

The radius of the sphere can use the formula for surface area to find the answer:

Surface area = 4πr²

Surface area = 4π(2²)

Surface area ≈ 50.27 square feet

Step-by-step explanation:

The statement that correctly declares a two-dimensional integer array is C. int Matrix[ ][ ] = new int[5][4];

To declare a two-dimensional array, we need to specify the data type of the elements, the number of rows, and the number of columns. In this case, the data type is int, the number of rows is 5, and the number of columns is 4. Therefore, the correct declaration is:

int Matrix[ ][ ] = new int[5][4];

Statements A, B, and D are incorrect because they do not specify the number of columns. Statement A also does not specify the number of rows.

When declaring a two-dimensional array, the square brackets ([]) are used to indicate that the array is two-dimensional. The number of rows is specified between the first two square brackets, and the number of columns is specified between the second two square brackets.

Step-by-step explanation:

You add up all of the points and divide by 5.

        Hence, The Value of:  a^2   +   b^2   is  18

        b  =  1/a  =  1/ 2 + √5

        b  =  1/2 + √5  *   2 - √5/2 - √5

            =     2  - √5/1

        b  =  2  -  √5

       a^2    =  (2  +  √5)^2    =  4  +  4√5  +  5

       b^2    =  (2   -  √5)^2    =  4   -  4√5  +   5

        a^2   +  b^2   =   4  +  4√5  +  5  +  4  -  4√5  +  5

                              =   18  -  3√5

        4    +  5     +  4  +  5

        9    +   4     +   5

       13   +   5   =   18

        a^2  +  b^2       =   18                

        a^2  =  18   -  b^2

The p-value of the test claim is calculated as; p < 0.00001.

The z-score between two samples is expressed as;

z =  (x₁ – x₂)/√(σ₁²/n₁) + (σ₂²/n₂)

The parameters given are;

Sample mean 1: x₁ = 23.38

Sample mean 2: x₂ = 18.69

Sample standard deviation 1: σ₁ = ?

Sample standard deviation 2: σ₂ = ?

Sample size 1: n₁ = 40

Sample size 2: n₂ = 35

standard error = sample standard deviation /√(sample size)

σ₁ = 23.38/√40

σ₁ = 3.697

σ₂ = 18.69/√35

σ₂ =  3.159

Thus;

z = (23.38 – 18.69)/√(3.697²/40) + (3.159²/35)

z = (23.38 – 18.69)/0.792

z = 5.92

Answer:

Step-by-step explanation:

T∘S represents a rotation of 75° about the line passing through points 4 and 2. It is the composition of a 45° rotation and a subsequent 30° rotation.

To find the composition of T∘S (T followed by S), we need to apply the individual transformations to a point and then apply the resulting transformation to another point.

Let's consider a point P. First, we apply the rotation S by 45° about point 4 to point P, resulting in a new point P'. Then, we apply the rotation T by 30° about the point 2 to point P'. The final position of P after both rotations is denoted as T∘S(P).

Geometrically, the composition T∘S represents the combined effect of rotating an object first by 45° about the point 4 and then rotating the resulting object by an additional 30° about the point 2. The resulting transformation is a rotation of 75° (45° + 30°) about an axis that passes through both points 4 and 2.

In summary, T∘S represents a rotation of 75° about the line passing through points 4 and 2.

If a $52 item is marked up by 10%, its new price will be:

$52 + 10% of $52 = $52 + $5.20 = $57.20

Then, if this new price is marked down by 10%, the final price will be:

$57.20 - 10% of $57.20 = $57.20 - $5.72 = $51.48

Answer:

Step-by-step explanation:

Given:

t = 2 ( 2h/32 ) ^1/2 ( or: t = 2 * sqrt ( 2h/32) ).

Step 1: First Player

0.9 = 2 * sqrt( 2h/32 )   / ^2 ( we will square both sides of equation )

0.81 = 4* 2h/32

0.81 = h/4

h 1 = 0.81 * 4 = 3.24 ft

Step 2: Second Player

0.8 = 2 * sqrt( 2h/32 ) /^2

0.64 = 4 * 2 h/32

h 2 = 0.64 * 4 = 2.56 ft

Step 3: Simplify

h 2 - h 1 = 3.24 - 2.56 = 0.68 ft

and since 12 in = 1 ft:

0.68 * 12 = 8.16 in ≈ 8 in.
