Answer:

13.5

Step-by-step explanation:

In this formula, v is velocity, u is the starting velocity, a is the acceleration, and t is the time. Using this knowledge, we can plug in our given information into the formula.

v=u+at

v=3+1.5*7

Now, we can solve for v, velocity.

v=3+10.5

v=13.5

The parameter u in a paired t procedure represents the mean difference in the responses to the two groups within pairs of subjects in the entire population.

This means that u captures the average change or effect observed when comparing the two related groups.

To elaborate further:

The parameter u represents a specific measure of interest in a paired t procedure.  In a paired t procedure, the data consists of paired observations, where each observation is made on the same subject or item under different conditions.

The parameter u represents the mean difference between the paired observations for the entire population. It quantifies the average change or effect observed between the two groups being compared within the pairs of subjects. By estimating the value of u from a sample, we can make inferences about the population parameter and test hypotheses regarding the difference between the two groups.

The distance between 5/2 and 4 7/8 on the number line is; 2 3/8. The value of the first two options are 7 3/8. The correct option is the third option.

C. None of the above

A number line consists of a line with numbers which are marked at intervals such that it \can be used to perform mathematical operations.

The fractions in the question is presented as follows;
5/2, 4 7/8

The fraction, 4 7/8, can be expressed as improper fractions as follows;

4 7/8 = (8 × 4 + 7)/8 = 39/8

The distance or difference between the fractions in the number line can therefore be found as follows;

The distance between 5/2 and 4 7/8 = The difference between 5/2 and 4 7/8

The difference between 5/2 and 4 7/8 = 4 7/8 - 5/2 = 39/8 - 5/2

39/8 - 5/2 = (39 - 4×5)/8 = 19/8 = 2 3/8

The options in the question are;

|(-5/2) - (4 7/8)| = |-5/2 - 39/8| = |(-5 × 4 - 39)/8| = |-59/8| = 7 3/8

|5/2 - (-4 7/8)| = |5/2 + 4 7/8| = |5/2 + 39/8| = |59/8| = 7 3/8

The above options therefore are not representative of the distance between 5/2 and 4 7/8 on the number line.

The correct option from among the options is therefore option C.

Answer:

Step-by-step explanation:

divide by 12

The normalization of a vector of u and v are (15/17)i+(-6/17)j+(8/17)k and (pi/sqrt(pi^2+50))i+(7/sqrt(pi^2+50))j-(1/sqrt(pi^2+50))k, (5/sqrt(26))j-(1/sqrt(26))i and (-1/sqrt(2))j+(1/sqrt(2))i, (7/sqrt(66))i-(1/sqrt(66))j+(4/sqrt(66))k and (1/sqrt(3))i+(1/sqrt(3))j-(1/sqrt(3))k respectively.

To normalize a vector, first find its magnitude, which is the square root of the sum of the squares of its components. Then, divide each component by the magnitude. After normalization, the vector will have a magnitude of 1 and can be used in various calculations such as dot product and cross product.

For vector u,

||u||=sqrt(15^2+(-6)^2+8^2)=17

u_normalized=u/||u||=(15/17)i+(-6/17)j+(8/17)k

For vector v,

||v||=sqrt(pi^2+7^2+(-1)^2)=sqrt(pi^2+50)

v_normalized=v/||v||=(pi/sqrt(pi^2+50))i+(7/sqrt(pi^2+50))j-(1/sqrt(pi^2+50))k

For vector u,

||u||=sqrt(5^2+(-1)^2)=sqrt(26)

u_normalized=u/||u||=(5/sqrt(26))j-(1/sqrt(26))i

For vector v,

||v||=sqrt((-1)^2+1^2)=sqrt(2)

v_normalized=v/||v||=(-1/sqrt(2))j+(1/sqrt(2))i

For vector u,

||u||=sqrt(7^2+(-1)^2+4^2)=sqrt(66)

u_normalized=u/||u||=(7/sqrt(66))i-(1/sqrt(66))j+(4/sqrt(66))k

For vector v,

||v||=sqrt(1^2+1^2+(-1)^2)=sqrt(3)

v_normalized=v/||v||=(1/sqrt(3))i+(1/sqrt(3))j-(1/sqrt(3))k

Answer:

20.25 kg

Step-by-step explanation:

Set up a proportion, where x is the number of kg in the barbell

\(\frac{1}{0.45}\) = \(\frac{45}{x}\)

Cross multiply:

x = 45(0.45)

x = 20.25

So, there are 20.25 kg in the barbell

Answer:

the barbell weighs 20.25 kg

Step-by-step explanation:

It's quite easy to find the answer! All you have to do is multiply .45 kg by 45!

so the equation would be:

The influence of a small alpha level in the context of hypothesis testing is:

c. A small alpha level reduces the likelihood of a Type I error.

A hypothesis known as the null hypothesis states that sample observations are the result of chance.

The correct statement regarding the influence of a small alpha level in the context of hypothesis testing is:

c. A small alpha level reduces the likelihood of a Type I error.

A small alpha level (typically denoted as α) is the significance level used in hypothesis testing to determine the threshold for rejecting the null hypothesis. By setting a small alpha level, such as 0.01 or 0.05, we are reducing the probability of making a Type I error, which is the incorrect rejection of a true null hypothesis.

In other words, a small alpha level provides a stricter criterion for rejecting the null hypothesis, making it less likely to reject the null hypothesis when it is true. This reduces the likelihood of claiming a significant result when there is no true effect or relationship in the population.

Based on the density and the given parameters, the density of the sheet of glass in kg per m cubed is 2500 kg/m cubed

The density of the sheet of glass  is given as

Density = 2.5g/cm cubed

Start by converting grams (g) to kilogram (kg)

This is done by dividing 2.5 by 1000

So, we have:

Density = 2.5/1000 kg/cm cubed

Evaluate the quotient

Density = 0.0025 kg/cm cubed

Next, we then convert cm cubed (cm^3) to meter cubed (m^3)

This is done by dividing the volume by 1000000

So, we have:

Density = 0.0025 kg/(1/1000000) m cubed

Express as product

Density = 1000000 * 0.0025 kg/m cubed

Evaluate the product

Density = 2500 kg/m cubed

Based on the density and the given parameters, the density of the sheet of glass in kg per m cubed is 2500 kg/m cubed

Answer:

See below

Step-by-step explanation:

Are you wanting to convert density of   gm/ cm^3   to    kg/m^3 ??

    there are 100 x 100 x 100  cm^3 =  1,000,000  cm^3/ m^3

2.5 gm / cm^3   *  1 000 000 cm^3 / m^3   =  2, 500 000 gm / m^3

   now 1 kg is   1000 gm

2, 500 000 gm / m^3   *  1 kg / 1000 gm  = 2500 kg / m^3

An inequality that could represent the possible values for the number of tables sold, t, and the number of chairs sold, c, that would satisfy the constraint : 150c + 750t ≥ 12000

Let the number of chairs sold = c

Let the number of tables sold = t

the price for each chair = $150

the price for each table = $750

The inequality that could represent the number of tables and chairs sold will be:

(150 × c) + (750 × t) ≥ 12000

150c + 750t ≥ 12000

Therefore,  an inequality that could represent the possible values for the number of tables sold, t, and the number of chairs sold, c, that would satisfy the constraint : 150c + 750t ≥ 12000
