Answer:

There is not enough evidence to support the claim that women who exercise daily have a significantly different duration of labor than all women.

Standard error sm = 1.634

Test statistic t = 1.102

P-value = 0.28

Step-by-step explanation:

This is a hypothesis test for the population mean.

The claim is that women who exercise daily have a significantly different duration of labor than all women.

Then, the null and alternative hypothesis are:

\(H_0: \mu=16\\\\H_a:\mu\neq 16\)

The significance level is 0.05.

The sample has a size n=29.

The sample mean is M=17.8.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=√77.4=8.8.

The estimated standard error of the mean is computed using the formula:

\(s_M=\dfrac{s}{\sqrt{n}}=\dfrac{8.8}{\sqrt{29}}=1.634\)

Then, we can calculate the t-statistic as:

\(t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{17.8-16}{1.634}=\dfrac{1.8}{1.634}=1.102\)

The degrees of freedom for this sample size are:

\(df=n-1=29-1=28\)

This test is a two-tailed test, with 28 degrees of freedom and t=1.102, so the P-value for this test is calculated as (using a t-table):

\(\text{P-value}=2\cdot P(t>1.102)=0.28\)

As the P-value (0.28) is bigger than the significance level (0.05), the effect is not significant.

The null hypothesis failed to be rejected.

There is not enough evidence to support the claim that women who exercise daily have a significantly different duration of labor than all women.

Answer:

b = 13.5

Step-by-step explanation:

2 -b/3 = -5/2

im assuming we want to find b. therefore we want b = something. so because b is on top of a fraction right now, I will multiply both sides by 3 so -b is not on top of a fraction anymore.

6 -b = -15/2

we should get rid of the divided by 2 on the other side too, to make it easier. we can do this by multiplying 2 on both sides.

12 - 2b = -15

remember, we want to isolate b. so first we should get rid of the 12 next to the 2b. we can do this by subtracting 12 on both sides!

-2b = -27  

finally, we can divide both sides by -2 and b will be isolated!

b = 13.5

The expression can be rewritten by given term as;  3^15

We need to simplify the expression below:

(3^2 x 3^3)^3

Remember that we can add these exponents, so we get:

(9 x 9)^3 = 81^3

Then we can rewrite this as:

531441

Takin the product between the exponents we will get:

(3^5)^3

Thus, the solution is 3^15

Step-by-step 4×-3= -12

-12 × -3= 36

and so on

The radian solutions of the equation are θ = 2.71 and θ = 0.43 radians

From the question, we have the following parameters that can be used in our computation:

-sin² (θ) - 2sin (θ) + 1 = 0

Divide through by -1

So, we have

sin² (θ) + 2sin(θ) - 1 = 0

Let y = sin(θ)

So, we have

y² + 2y - 1 = 0

When solved graphically, we have

y = 0.414 and -2.414

This means that

sin(θ) = 0.414 and sin(θ) = -2.414

Take the arcsin of both sides

θ = 2.71 and θ = 0.43

Hence, the angles are θ = 2.71 and θ = 0.43

Step-by-step explanation:

To estimate the area under the curve y=x+1 between x=0 and x=10 with n=5 sub-intervals, you can use the following steps in a spreadsheet program like Microsoft Excel:

Create a table with three columns labeled "x", "y", and "Area".

In the "x" column, enter the values 0, 2, 4, 6, 8, and 10 (these are the endpoints and midpoints of the sub-intervals).

In the "y" column, enter the corresponding y-values for each x-value. For example, for x=0, y=1; for x=2, y=3; for x=4, y=5; and so on.

In the "Area" column, calculate the area of each sub-interval using the trapezoidal rule. The formula for the area of a trapezoid is:

Area = (base1 + base2) * height / 2

where base1 and base2 are the lengths of the two parallel sides of the trapezoid (which are the y-values of the function at the endpoints of the sub-interval), and height is the width of the sub-interval (which is 2 in this case).

Add up the areas of all the sub-intervals to get an estimate of the total area under the curve.

The completed table should look like this:

x y Area

0 1 0

2 3 4

4 5 8

6 7 8

8 9 4

10 11 0

To calculate the total area under the curve, simply sum the values in the "Area" column, which gives an estimate of 24 square units. This can be used to determine the amount of mulch needed for the garden bed.

As xv = 6 and a=20, we can find b as:

As the y-coordinate of the vertex is:

The cake sharing process of the process using geometric progression gives the following values;

1. The amount of the cake left after the first division is one quarter of the cake

The amount of cake remaining after the fourth division is 1/256 of the original cake

2. The series is; (1/4 + 1/16 + 1/64+ 1/256 + 1/1024) of the original cake

3. 341/1024 of the original cake

4. If the process continues indefinitely each person gets (1/3) of the original cake

A geometric progression is a sequence of numbers such that a term is found from the previous term by multiplying the previous term by a constant number.

1. Taking the dimensions of the cake as a square, let x represent the side length of the cake, we have;

Amount of cake left after the first division = x/4

Amount left after the second sharing = x/(4×4) = x/16

Amount left after the third division = x/(4×4) = x/(16×4) = x/64

Amount left after the fourth division = x/(64×4) = x/256

2. After the fourth division, each person receives x/(256×4) = x/1024

The series that represents the amount each person receives after the fourth division is therefore;

3. The amount of the original cake each person gets after the fourth division is therefore;

4. The amount each person receives is given by the sum of a geometric series up to infinity, where;

The first term, a = 1/4

The common ratio, r = 1/4

S = (1/4)/(1 - (1/4)) = (1/4)/(3/4) = (1/4)×(4/3) = 1/3

The amount of the original cake each gets if the process continues indefinitely is (1/3) of the original cake.

How yo illustrate the information?

It should be noted that because the business is using the allowance approach in this instance, the write-off entry would not be to the account for bad debts. To write off an account, a debit must be made to a separate account that is kept as an allowance for dubious accounts.

statement justification

PQ = OQ given

m∠1 = m∠2 given

m∠1 + m∠AXO = 180 supplementary angles

m∠2 + m∠OQB = 180 supplementary angles

m∠AXO = m∠OQB congruent angles

m∠AOX = m∠QOB congruent angles

m∠XAO + m∠AOX + m∠AXO = 180 sum of internal angles of a triangle

m∠OQB +m∠QOB + m∠QBO = 180 sum of internal angles of a triangle

m∠XAO = m∠QBO congruent angles

m∠XAO = m∠QBO is the same as ∠A = ∠B

For the steps which involve supplementary angles you consider that if m∠1 = m∠2 it is necessary that m∠AXO = m∠OQB.

For the steps which involve the sum of internal triangle, you consider if m∠AXO = m∠OQB and m∠AOX = m∠QOB it is necessary m∠XAO = m∠QBO

The measure of other two angles in the given quadrilateral are 10° and 25°.

A quadrilateral is a polygon with four sides four angles and four vertices. Whenever we name a quadrilateral, we need to keep in mind the order of the vertices.

Given that, two angles of a quadrilateral measure 130° and 195°.

The other two angles are in a ratio of 2:5.

So, the other two angles are 2x and 5x

Now, 130°+195°+2x+5x=360°

325°+7x=360°

7x=360°-325°

7x=35°

x=5

So, 2x=10° and 5x=25°

Therefore, the measure of other two angles in the given quadrilateral are 10° and 25°.
