You need at least 5000 points to earn a gift card from your bank. You currently have 2700 points.You deposit money in your savings account and earn an additional 400 points.
a. Write an equation and inequality that represents the number of points you need to earn a gift card.
b. Change the above equation or inequality to include the additional 400 points.
Answer:
A.) 5000p-2700p= 2300p B.) 5000p-2700p-400p=1900p
Step-by-step explanation:
A. Is how many points you need after having the 2700. B. Is how many points you need after depositing the money. p=points
You pick a card at random from an ordinary deck of 52 cards. If the card is an ace, you get 9 points; if not, you lose 1 point. 2 lines connect and go up to the right and down to the right. The line that goes up to the right points to Ace, and the line that goes down to the right points to Not an ace. StartFraction 4 Over 52 EndFraction is above the lines, and StartFraction question mark Over 52 EndFraction is below the lines. Write the equation for the expected value. E(V) = 4 52 (a) + b 52 (c) a = b = c =
The equation of the expected value is [tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]
How to determine the equation of the expected valueIn a standard deck of cards, there are:
Ace = 4
Cards = 52
So, the probability of selecting an ace is:
[tex]p = \frac{4}{52}[/tex]
Simplify
[tex]p = \frac{1}{13}[/tex]
The probability of not selecting an ace is calculated using the following complement rule
[tex]q = 1 - \frac{1}{13}[/tex]
Simplify
[tex]q =\frac{12}{13}[/tex]
The expected value is then calculated as:
[tex]E(x) = \sum x * P(x)[/tex]
This gives
[tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]
Hence, the equation of the expected value is [tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]

A hovercraft takes off from a platform. It’s height (in meters), x seconds is modeled by h(x)=-(x-11)(x+3). What is the height of the hovercraft at the time of the takeoff?
Answer:
The height of the hovercraft at the time of takeoff is 33 meters.
Step-by-step explanation:
Height of hovercraft x seconds after takeoff = h(x) = -(x - 11)(x + 3)
Height after takeoff is = h(0) = -(0 - 11)(0 + 3) = -(-11)(3) = 33
So the correct answer is 33 meters. The height of the hover craft at the time of the takeoff is 33 metres.
Answer: 33 meters.

which linear inequality is represented by the graph?
Answer:
the second one
Step-by-step explanation:
The y-intercept is -4 so we can eliminate the third and fourth options. Substitute (0,0) into the equation and from that we can say that it is not true (0 is not less than -4). Because it isn't true, we shade in the side that doesn't have the origin in it.
If ABC is reflected across the y-axis, what are the coordinates of A? A (1-3)
B. (-1, -3)
C. (5,-3)
D. (-1,3)
Answer:
d. (-1, 3)
Step-by-step explanation:
Reflecting across y axis means the x coordinate will change.
Imagine a mirror image of the triangle on the other side of Y axis.
A's coordinates on the right are (1, 3)
So if we flip across Y the coordinates will now be (-1, 3)
3 stays the same because it is still in the same position vertically.
The correct option will be Option B: When ABC is reflected about the y-axis, then the coordinate of A will be(-1,-3).
What is reflection?Reflection is the transformation of the picture about an axis so that the distance of the reflected image from the axis is the same as the distance of the original image from the axis.
When a point of coordinate (x,y) is reflected by the y-axis then the coordinate of the reflected point will be of coordinate (-x,y).
Given that the triangle ΔABC is reflected across the y-axis.
The coordinate of point A is (1,-3).
When point A of triangle ΔABC is reflected by the y-axis, then the coordinate of y will not change. The mirror image of the triangle will be on the other side of the y-axis.
As we know When a point of coordinate (x,y) is reflected by the y-axis then the coordinate of the reflected point will be of coordinate (-x,y).
Then the coordinate of the reflected point A will be (-1,-3).
Therefore when ABC is reflected about the y-axis, then the coordinate of A will be(-1,-3).

Answer:
32 degrees.
Step-by-step explanation:
So every triangle =180 degrees.
Firstly, 14 + 45 = 59
Secondly, 180 - 59 = 121
so angle AEB = 121 degrees.
Using vertical angles theorum, angles AEB and CED are equal to each other
so CED = 121 degrees.
121 + 27 = 148
then 180 - 148 = 32
Angle D = 32 degrees

A right triangle has a hypotenuse with length 13 in. and a leg with length 12 in. Find the area of triangle
Answer:
[tex]30 {in}^{2} [/tex]
Step-by-step explanation:
First we have to find the value of the other leg of the triangle. To find that we can use the PYTHAGORAS theorem because this is an right triangle.
[tex] {h}^{2} = {p}^{2} + {b}^{2} \\ {13}^{2} = {12}^{2} + {b}^{2} \\ 169 = 144 + {b}^{2} \\ 169 - 144 = {b}^{2} \\ 25 = {b}^{2} \\ b = \sqrt{25 } \\ b = 5 \: \: in[/tex]
Now let's find the area.
[tex]area = \frac{1}{2} \times base \times height \\ = \frac{1}{2} \times 5 \times 12 \\ = \frac{60}{2} \\ = 30 {in}^{2} [/tex]

To prove triangles similar, we only need to prove corresponding angles congruent OR corresponding sides are proportional. However, with a quadrilateral, we need to prove corresponding angles congruent, AND corresponding sides are proportional. Explain in your own words why it takes more to prove quadrilaterals congruent. Include examples demonstrating how "just angles" or "just sides" is not enough.

Seven different names were put into a hat. A name is chosen 106 times and the name Josh is chosen 19 times. What is the THEORETICAL probability of the name Josh being chosen?
HELPPPPPPPP
We will see that the theoretical probability that the name Josh is chosen is P = 1/7.
How to find the theoretical probability?7 names are put on a hat, theoretically, we assume that all the names have the same probability of being randomly drawn from the hat. So it does not depend on the given information, that would give us the experimental probability.
Then, for the theoretical probability we will have the quotient between the number of names in the hat that are Josh (there is only one) and the total number of names in the hat, this gives:
P(Josh) = 1/7
