What is the slope of a line perpendicular to the line in the graph?

Answer:

No

Step-by-step explanation:

If you divide the numerator by the denominator, 30/40 equals 0.75 in decimal form, so you did not reach your goal of 0.80.

Answer:

No, You didn't reach you goal of 80%, You only got 75% on the test.

Step-by-step explanation:

Given;

You answer 30 out of 40 questions correctly on a test.

To Find;

Did you reach your goal of 80%

Solve;

30 ÷ 40 × 100

[tex]\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations}[/tex]

[tex]30\div \:40=\frac{30}{40}[/tex]

[tex]\frac{30}{40}\cdot100[/tex]

[tex]=75[/tex]

Hence, No you didn't reach your goal of 80%

Answer:

Volume of the portion = 1.6 cubic inches

Step-by-step explanation:

Since, wooden dowel is in the shape of a cylinder,

Formula to be used to find the volume of the part Anna has cut from the dowel will be,

Volume = πr²h

Where r = radius of the cylinder or part of the wooden dowel

h = length of the portion

By substituting the values in the formula,

Volume = π(0.5)²(2)

             = 0.5π

             = 1.57 in³ ≈ 1.6 cubic inch

Therefore, volume of the portion will be 1.6 in³.

The volume of oil inside the tank at [tex]t = 15\,h[/tex] is approximately 66.556 liters.

In this question we must estimate the volume by Riemann sum, which consist in sum of all areas of the trapezoids of equal width in the volume rate versus time graph. The right Riemann sum with three intervals for this case is described below:

[tex]Q = \Sigma \limits_{i=0}^{2} \left\{R_{i}+\frac{1}{2}\cdot [R_{i+1}-R_{i}] \right\}\cdot \Delta t[/tex]

[tex]Q = \left[6.5+\frac{1}{2}\cdot (6.2-6.5) \right]\cdot (3.667)+\left[6.2+\frac{1}{2}\cdot (5.9-6.2)\right]\cdot (3.667) +\left[5.9+\frac{1}{2}\cdot (5.6-5.9) \right]\cdot (3.667)[/tex]

[tex]Q \approx 66.556\,L[/tex]

The volume of oil inside the tank at [tex]t = 15\,h[/tex] is approximately 66.556 liters. [tex]\blacksquare[/tex]

The table of the volume rate versus time is missing, all missing values of the table are included below:

[tex]R(4) = 6.5\,\frac{L}{h}[/tex], [tex]R(7.667) = 6.2\,\frac{L}{h}[/tex], [tex]R(11.333) = 5.9\,\frac{L}{h}[/tex], [tex]R(15) = 5.6\,\frac{L}{h}[/tex]

Step-by-step explanation:

Answer:

f(3)= -18

Step-by-step explanation:

f(x)= -3(x+3)

putting the value 3 in place of x

f(3)= -3(3+3)

or,f(3)= -3(6)

or,f(3)= -18

Answer:

75?

Step-by-step explanation:

Isnt the total of the line suppose to equal 180*?  if thats the case then the first angle 101* is 11 over the 90* mark meaning that you take 11 from the other side which would be 90-11 and that leave you with 79 but since the problem says +4 you would take 4 from 79 leaving you with 75.  You would work backwards on the problem so the whole thing equals 180*

Step-by-step explanation:

0.3

A. greater than 0.3

The Margin of error is 0.3 when assuming a 90% confidence level.

It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.

The formula for finding the MOE:

MOE = z score * s/√n

Where   is the z score at the confidence interval

            s is the standard deviation

            n is the number of samples.

here, we have,

It is given that among 320 randomly selected airline travelers, the mean number of hours spent traveling per year is 24 hours and the standard deviation is 2.9.

It is required to find the margin of error when the confidence level is 90%.

We have in the question:

at 90% confidence interval = 1.645 (From the Z score table)

s = 2.9

n = 320

Put the above values in the formula, we get:

MOE = 0.2666

Rounding the nearest tenth:

MOE = 0.3

Thus, The Margin of error is 0.3 when assuming a 90% confidence level.

Answer:

unbiased sample

Step-by-step explanation:

The population is divided into similar, nonoverlapping groups. A simple random sample then selected from each group.

A biased sample is the opposite of unbiased sample.

Answer:

[B] unbiased

Step-by-step explanation:

Let's first define each answer choice;

Biased sample: sample not representative of the entire population.

Unbiased sample: sample where every member of the population has an equal chance of being selected.

Convenience sample: sample where representatives are easily accessible.

Free sample: Sample of small amount

Thus, base on the define of the answer choices we can know that

[B] unbiased sample is the correct answer.

Answer:

m(arc)PM = 139°

Step-by-step explanation:

m<N = (1/2)[m(arc)PM - m(arc)OM]

59 = (1/2)[m(arc)PM - 21]

118 = m(arc)PM - 21

m(arc)PM = 139°

Answer:

The steps to do this :

[tex]2(g - h) = b + 4[/tex]

[tex]g - h = \frac{b + 4}{2} [/tex]

[tex]g = \frac{b + 4}{2} + h[/tex]

[tex]g = \frac{b}{2} + \frac{4}{2} + h[/tex]

[tex]g = \frac{b}{2} + 2 + h[/tex]

2(g - h)=b + 4

Use the distributive property on the left side:

2g - 2h = b +4

Add 2h to both sides:

2g = 2h + b + 4

Divide both sides by 2:

g = (2h + b + 4)/2

Simplify:

g =  b/2 + 2 + h ( note the order of h, 2 and b/2 can be different)

a. The solar system travels about 188495.56 light years each year.

b.  the solar system is circling the center of the galaxy at about 520000 mi/hr

The solar system travels about 188495.56 light years each year.

Since the distance the solar system travel around the milky way is a circular orbit. The distance travelled is the circumference of a circle.

So, the circumference C = 2πr where

So, C = 2πr

= 2π × 30000 light years

= 60000π light years

= 188495.56 light years

So, the solar system travels about 188495.56 light years each year.

The solar system is circling the center of the galaxy at about 520000 mi/hr

The speed of the solar system circling the milky way is given by v = rω where

So, substituting the values of the variables into the equation, we have

v = rω

v = 1.764 × 10¹⁷ miles × 2.97 × 10⁻¹² radians per hour

v = 5.23908 × 10⁵ miles/hour

v = 523908 miles/hour

v ≅ 520000 mi/hr to the nearest ten thousand

So, the solar system is circling the center of the galaxy at about 520000 mi/hr
