Answer:

D. 0, 1, or 2 solutions

Step-by-step explanation:

The line represented by g(x) may intersect the parabola represented by f(x) in 0, 1, or 2 places, as illustrated in the attachment. The curves are different shapes, so cannot overlap to give infinite solutions.

The system may have 0, 1, or 2 solutions.

find the value of x in the following figure

Answers

Answer:

x = 172

Step-by-step explanation:

A circle is 360 degrees

The angles will add to 360 degrees

x/2 + 59 + x/4 + x = 360

Subtract 59 from each side

x/2 + x/4 +x +59-59 = 360 -59

x/2+x/4+x = 301

Combine like terms

2x/4 +x/4 +4x/4 = 301

7/4x = 301

Multiply each side by 4/7 to isolate x

4/7 * 7/4 x = 301 *4/7

x =172

On the grid, draw graphs of y=x+2 and x+y=3

Answers

Try getting a graphing calculator they help a lot

Answer:

The image shows the answer and below I will explain more about it.

Step-by-step explanation:

To draw a line all you need is two points on the graph, and people mainly use the coordinates of the y and x intercepts to draw it (when x=0 and when y=0)

so for these questions all we do is:

y=0+2 (we are putting x=0 into the equation)

y=2, x=0 so this is the first of our set of coords:

0=x+2

x=-2 y=0 (we are putting y=0 into the equation)

so all you do is plot these in and draw a line which passes between both,

now just repeat for the other one :)

A researcher wishes to determine what percentage of college freshmen also work full time. To do this, the researcher obtains a list of all enrolled freshunen, manipulates the list so that females appear twice is often as males, and then selects from this list

a. Probability Sampling
b. Convenience Sampling
c. Voluntary Sampling
d. Stratified Sampling
e. None of the above

Answers

Answer:

d. Stratified Sampling

Step-by-step explanation:

Stratified Sampling is a form of sampling in which the researcher selects a population sample based on a demographic factor or strata such as race or gender. From the different strata, a random sample is then made such that each group or subpopulation is represented in the final sample.

It should be noted that retaining the percentages while selecting a randomized sample is essential to stratified sampling.

Hence, in this case, when the researcher obtains a list of all enrolled freshmen, manipulates the list so that females appear twice as often as males, and then selects from this list, this is an example of stratified sampling

Step-by-step explanation:

same as other side should be

but i dont know why theres a 45 :(

Length of missing side is 36 units.

What is Ratio?

Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

Let length of missing side is x

Since horizontal lines are parallel, so ratio of sides are equal

20/16 = 45/x

x= (45/20)16

x = 36

Hence, length of missing side is 36 units.

The power generation plant of a ship is outfitted with two identical diesel-generator sets. One single set running stand-alone can meet the full power requirement of the vessel. The engine of each set has a malfunction probability of 25% and the generator of 10%. In case one set breaks down there is a 50% probability of it being repaired but it will run again only if repaired and its subsystems do not further malfunction upon startup. Calculate the probability of an electric power outage shipboard.

Answers

Answer:

probability of an electric power outage shipboard is 0.075 or 7.5 %

Step-by-step explanation:

Given the data in the question;

Probability of engine malfunction = 25% = 0.25

Probability of generator malfunction = 10% = 0.1

Probability of generator being repaired = 50% = 0.5

probability of an electric power outage shipboard = ?

To get the probability of an electric power outage shipboard, we use the expression;

probability of an electric power outage = 2[tex]_c_1[/tex] × p( Probability of generator malfunction ) × p( Probability of generator being repaired ) × ( 1 - p( Probability of engine malfunction ) )

so we substitute in our given values;

probability of an electric power outage = 2 × 0.1 × 0.5 × ( 1 - 0.25 )

probability of an electric power outage = 2 × 0.1 × 0.5 × 0.75

probability of an electric power outage = 0.075 or 7.5 %

What is the difference between the theoretical and experimental probabilities of getting heads?

A. 0.5
B. 0.0
C. 0.3
D. 0.1

Answers

Answer:

c 0.3

Step-by-step explanation:

there is are 50/50 chance when a coin is flipped but according to the data it is 80/20 so if to take 80-50=30 so it is a 0.3 change in probability.

The difference between the theoretical and experimental probabilities of getting heads is 0.3.

What is Probability?

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

A fair, unbiased coin was flipped 10 times.

The result is shown in the table.

Total number of outcomes = 10

For the experimental probability,

Number of heads = 2

Experimental Probability of getting heads, E = 2/10 = 0.2

For the theoretical probability,

Theoretical Probability of getting heads, T = 1/2 = 0.5

Difference = 0.5 - 0.2 = 0.3

Hence the difference is 0.3.

Mean of 8, 3,5
and mean of 44,89,23

Answers

Answer:

mean of 8,3,5 = 5.333 or 16/3

mean of 44,89,23 = 52

Step-by-step explanation:

Answers and step-by-step explanations:

To find the mean, first, we are going to add all of the numbers, and divide by how many numbers there were. The first data set is:

8, 3, 5

Add them all up:

8 + 3 + 5 = 16

Then, since there were three numbers, we divide 16 by 3.

16/3 = 5.33

Therefore, the mean of 8, 3 and 5 is around 5.33.

The second data set is:

44, 89, 23

Add them up:

44 + 89 + 23 = 156

Then, divide it by how many numbers there were, which is 3.

156/3 = 52

Therefore, the mean of 44, 89 and 23 is 52. Hope this helps!

The lengths of the shorter sides are both sqrt(2^2 + 6^2) = sqrt(40)

Area = 1/2 x (sqrt(40))^2 = 20
