Please HELP. Thank you

Answers

It is either A or B,
I would go with A because the lengths of the sides don't abide by the pythagorean theorem rule: A^2 + B^2 = C^2

Point C to Point B appears to have a slope of 2/3, 3 blocks apart (in width) and 2 blocks apart (in height). Using a^2 + b^2 = c^2 will help where ^2 means (squared).
(2 x 2) + (3 x 3) = 13
Line CB is (square root) of 13.

Point A and B are 2 blocks apart (width) and 3 blocks apart (height), so using what we did in the last step...
(3 x 3) + (2 x 2) = 13
Line AB is (square root) of 13.

So now... With Line AB and Line CB being the square root of 13, the line AC should be (square root) (13 + 13), so (square root) 26. If it does equal this, then it is a right-triangle.

Point C and A are 1 block apart (width) and 5 blocks apart (height) so...
(1 x 1) + (5 x 5) = 26
Square root of 26...

In conclusion, the Triangle IS a Right-angle and you should pick "D"

How tall would a stack of 1000 pennies be in centimeters?

Answers

US Penny dimensions are:
Diameter: 19 mm
Thickness: 1.52 mm ( according to the US mint )
1000 * 1.52 = 1,520 mm = 1.52 m = 1 m 52 cm
Answer:
A stack of 1000 pennies would be 1 m 52 cm tall.

Final answer:

To calculate the height of a stack of 1000 pennies, multiply the thickness of one penny (0.1524 cm) by 1000. The total height would be 152.4 cm.

Explanation:

Calculating the Height of a Stack of 1000 Pennies

To calculate the height of a stack of 1000 pennies, we first need to know the thickness of one penny. Unfortunately, the data provided talks about the volume of a stack of 100 bills, which is not directly relevant to our problem. However, by using the correct information, we find that a US penny is approximately 0.0598 inches (or 0.1524 cm) in thickness. So the calculation for the height of 1000 pennies stacked would be as follows:

Thickness of one penny = 0.1524 cmTotal height = 0.1524 cm/penny × 1000 penniesTotal height = 152.4 cm

Thus, the height of a stack of 1000 pennies would be 152.4 centimeters.

A group of men and women were asked what their favorite pet was, and the results of the survey were tabulated.Petey is considering investing $19 in a certain company. Financial advisors forecast that there is a 30% chance that the stock will increase in value by 10%, and a 70% chance he will lose his initial investment. Determine if Petey should make the investment, and find the expected value of the investment.

Answers

You question is of two parts.
For the first part:
A group of men and women were asked what their favorite pet was, and the results of the survey were tabulated.

[tex]\begin{center} \begin{tabular} {|c|c|c|c|c|} & Cats & Dogs & Other & Total \\ [1ex] Male & 42 & 58 & 6 & 106 \\ Female & 52 & 48 & 2 & 102 \\ [1ex] Total & 94 & 106 & 8 & 208 \end{tabular} \end{center}[/tex]

Let event A be defined as randomly choosing someone who picked cats or dogs as their favorite pet. Let event B be defined as a randomly chosen person being male.
Find P(B| NOT A).

P(A) = P(choosing cat) + P(choosing dog) = [tex] \frac{94}{208} + \frac{106}{208} = \frac{200}{208} = \frac{25}{26}[/tex]
P(NOT A) = [tex]1- \frac{25}{26} = \frac{1}{26} [/tex]
P(B and NOT A) = P(males that did not choose cat or dog) = [tex] \frac{6}{208} = \frac{3}{104} [/tex]

P(B | NOT A) = [tex] \frac{P(B \, and \, NOT \, A)}{P(NOT \, A)} = \frac{ \frac{3}{104} }{ \frac{1}{26} } =\frac{3}{104}\times26= \frac{3}{4} [/tex]

For the second part of the question.
Petey is considering investing $19 in a certain company. Financial advisors forecast that there is a 30% chance that the stock will increase in value by 10%, and a 70% chance he will lose his initial investment. Determine if Petey should make the investment, and find the expected value of the investment.

If his investment increases by 10%, the value of the investment will be 1.1 x $19 = $20.90 with a probability of 30% or 0.3

The expected value of the investment is given by
[tex]\$20.90\times0.3+(-\$19\times0.7)=\$6.27-\$13.30=-\$7.03[/tex]

Therefore, Petey should not make the investment as there is an expectation of a loss from the investment.

What is the point slope equation of the line with slope -12 that goes through the points (5, 3)?

Answers

The point-slope form of ay line is:

y-y1=m(x-x1), where m=slope and (x1,y1) is any point on the line.

In this case we are given that m=-12 and (x1,y1) is (5,3) so

y-3=-12(x-5)

Answer:

y = -12x + 63

Step-by-step explanation:

- The equation of a line in a cartesian coordinate system is given by the following linear relationship:

y = mx + c

- The constants m and c are to be determined.

- The constant m denotes the slope of the line which is given as -12.

- To evaluate constant c we will plug the slope m = -12 and use the given point ( 5 , 3 ) as the lines passes through it. Hence, we have:

y = -12x + c

3 = -12(5) + c

3 = - 60 + c

c = 63

- Then the equation of the line can be expressed by plugging in the constants m and c as follows:

y = -12x + 63

What is the variance of the data? Round to the nearest hundredths.

Answers

Variance is the average of the square of the differences of each data with the mean. To calculate for the variance, we first calculate for the mean. Then, we subtract each data with the mean. Next, each difference would be squared and added. The resulting value would be divided on how many data are used. We calculate as follows:

Mean = 9 + 7 + 6.5 + 7.5 + 7 + 8 + 5 + 6 + 7.5 + 8 / 10
Mean = 6.4

Squared of the sum of the differences = (9-6.4)^2 + (7-6.4)^2 + (6.5-6.4)^2 + (7.5-6.4)^2 + (7-6.4)^2 + (8-6.4)^2 + (5-6.4)^2 + (6-6.4)^2 + (7.5-6.4)^2 + (8-6.4)^2 = 17.15

Variance = 17.15 / 10 = 1.715

What is the measure of a base angle of an isosceles triangle if the vertex angle measures 38° and the two congruent sides each measure 21 units?

Answers

Final answer:

The measure of a base angle in an isosceles triangle with a vertex angle of 38° is 71°, as isosceles triangles have two equal base angles and the total sum of angles in any triangle is 180°.

Explanation:

To calculate the measure of a base angle in an isosceles triangle, we need to remember that the sum of angles in a triangle is always 180°. Given that we have a vertex angle of 38°, we subtract that from 180° to find the sum of the two base angles. Since it's an isosceles triangle, these angles are equal:

180° - 38° = 142° (sum of both base angles)142° / 2 = 71° (measure of one base angle)

Therefore, the measure of one base angle in this isosceles triangle is 71°.

Final answer:

The measure of each base angle of an isosceles triangle is 71°.

Explanation:

An isosceles triangle has two congruent sides and two congruent base angles. In this case, the vertex angle measures 38° and the congruent sides each measure 21 units. To find the measure of a base angle, we can use the fact that the sum of the angles in a triangle is 180°. Since the vertex angle is 38°, the sum of the base angles is 180° - 38° = 142°. Since the base angles are congruent, we can divide 142° by 2 to find the measure of each base angle.

142° / 2 = 71°

Therefore, the measure of each base angle is 71°.

Hello there!

16x + 9 = 9y - 2x
Add 2x to both sides to isolate y (get it by itself on one side of the equation).

16x + 2x = 18x
-2x + 2x = 0

18x + 9 = 9y
Divide both sides by 9 to solve for y.
18x / 9 = 2x
9 / 9 = 1
9y / 9 = y

We are now left with:
2x + 1 = y

Describe how the graph of y=|x|-12 is like the graph of y=|x| and how it is different?

Answers

The graph of y = |x| - 12 can be transformed from y = |x| by:

Shift it downward by 12 units.

The whole shape of the two graphs will be the same.

Answer:

Both functions are similar, because basically they have the same behaviour, but the difference is that they start from a different vertex. The reason of this is because [tex]y=|x|-12[/tex] is a translation of [tex]y=|x|[/tex].

Basically, the first function is similar to the second one, but translated downwards 12 units.

So, they are similar in behaviour, we could say parallel, but different on the position of the vertex, the first is at y=-12, and the second one at y=0.

The graph of each function is attached, there you can observe the similarity and different we mentioned before.

If M is the midpoint of FG and MG = 7x-15, FG = 33, X = ?

Answers

7x-15=33 solve the equation and you should ger x= 2.57

The given expression gives x = 4.5.

If M is the midpoint of FG, this means that M divides FG into two equal segments. Therefore, FM = MG. We are given that MG = 7x - 15 and the total length of FG = 33. Hence, FM = MG = (1/2) * (FG).

Step-by-step solution:

Set up the equation for FM: FM = MG = (1/2) * 33.

This simplifies to FM = MG = 16.5.

Since MG = 7x - 15, we set 7x - 15 equal to 16.5.

Solve for x: 7x - 15 = 16.5.

First, add 15 to both sides: 7x = 31.5.

Finally, divide both sides by 7: x = 4.5.

Therefore, the value of x is 4.5.

You roll a six sided die and toss a coin. What is the probability of rolling an odd number and then getting heads?

Hello there! Thank you for asking your question here at Brainly! I will be assisting you with answering your question, and will teach you how to tackle it on your own in the future.

So, let's take a look at our question.
"You roll a six sided die and toss a coin. What is the probability of rolling an odd number and then getting heads?"

First, we need to understand what we're dealing with, and how to handle it.
Let's tackle these individually, rather than doing it all at once and getting confused/stuck.
We roll a six sided die, which is numbered from 1 to 6. "What is the probability of rolling an odd number?"
Well, let's count how many odd numbers there are from 1 to 6.
1, 3, 5; We have three odd numbers on our six sided die.
Let's set that up as a fraction, [tex] \frac{3}{6} [/tex]
However, we can simplify it into simpler terms - divide both numbers by 3.
3/3 = 1
6/3 = 2
We now have our simplified fraction, [tex] \frac{1}{2} [/tex]

Now, let's focus on the other half of the problem.
"You flip a coin. What's the probability of landing on heads?"
Well, a coin only has two sides - heads and tails - which means we have 1/2 chances of landing on heads or tails generally.

Since the question asks for the probability of an odd number and landing on heads, we need to multiply our fractions.

We have these two fractions:
[tex] \frac{1}{2} [/tex] * [tex] \frac{1}{2} [/tex]
Multiply them.
[tex] \frac{1}{2} [/tex] * [tex] \frac{1}{2} [/tex] = [tex] \frac{1}{4} [/tex]

Your answer is [tex] \frac{1}{4} [/tex]

In one baseball season, Peter hit twice the difference of the number of homeruns Alice hit and 6. Altogether, they hit 18 homeruns. how many homeruns did each player hit that
season?

Answers

In order to solve this problem, the approach should be formulating equations such that they form a system of linear equations. Let's start by assigning variables. Let x be the number of homeruns made by Peter, and y be the number of homeruns made by Alice. Therefore,

x = 2(y - 6)

This is the equation for the relationship between Peter's and Alice's hits. The second equation would be the sum of their hits:

x + y = 18

These are the two independent equations in order to solve the two unknowns, x and y. Substituting the first equation into the second equation,

2(y - 6) + y = 18
2y - 12 + y = 18
3y = 18 + 12
3y = 30
y = 10

Using y=10 to the first equation:
x = 2(10 - 6)
x = 8

Therefore, Peter made 8 homeruns, while Alice made 10 homeruns for a total of 18.
