The point F( – 4, – 1) i rotated 270° counterclockwie around the origin. What are the coordinate of the reulting point, F'?
The point F( – 4, – 1) i rotated 270° counterclockwie around the origin. then The coordinates of the point F' is (-1 ,4 )
Given that the point J(-2,1) is rotated about 270° about the origin.
Coordinates of the resulting point F':
Since, we know that, when rotating a point 270° counterclockwise about the origin, the point (x,y) becomes (y,-x) which means we switch the places of x and y coordinates and make x as negative.
Therefore, the transformation is given by
(x ,y) -> ( y , -x)
Using the above transformation, we have,
(-4 ,-1) ⇒ ( -1 , -(-4)) ⇒ (-1 , 4)
Therefore, the resulting point of the coordinates of the point F' is (-1 ,4)

Casho has a points card for a movie theater. She receives 55 rewards points just for signing up. She earns 2.5 points for each visit to the movie theater. She needs at least 90 points for a free movie ticket. Use the drop-down menu below to write an inequality representing v, the number of visits she needs to make in order to get a free movie ticket.
Answer: She need 14 visits to reach 90 points
Step-by-step explanation:
Let y be the number of points and v be the number of visits
We will have an equation
y= 2.5v + 55
Now we want to find the number of visits she needs to reach 90 points; we put 90 in the y.
90 = 2.5v +55
Subtracted 55 from both sides
35 = 2.5v
Divided both sides by 2.5
v= 14 visits
So she need 14 visits to reach 90 points

The rate of change of the given data between 3 and 7 hours is; 19 miles per hour
How to calculate the rate of change?We are told that rate of change is the difference between what the value of the data began at versus the value the data ended at.
Now, the formula for the rate of change between two coordinates (x₁, y₁) and (x₂, y₂) is;
Rate of change = (y₂ - y₁)/(x₂ - x₁)
Now, we are told that we should find the rate of change from 3 to 7 hours and so we first write the coordinates;
(3, 209) and (7, 285)
Thus;
Rate of change = (285 - 209)/(7 - 3)
Rate of change = 76/4

t= seconds
Dor

Answer:
The possible values of t for which the rocket's height is 12 meters are approximately 1.1 or -1.1.
Step-by-step explanation:
The height of the rocket after t seconds is given by the equation12 = 35t - 5t^2
t = (-b ± √(b^2 - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation. In this case, a = -5, b = 35, and c = -12.Plugging these values into the quadratic formula, we gett = (35 ± √(35^2 - 4(-5)(-12))) / 2(-5)
t = (35 ± √(35^2 + 240)) / -10
t = (35 ± √575) / -10
This gives us two possible values fort = (35 + √575) / -10 = (35 + 24) / -10 = 11/10 = 1.1
t = (35 - √575) / -10 = (35 - 24) / -10 = -11/10 = -1.1
Therefore, the rocket's height is 12 meters when t is approximately 1.1 or -1.1.The rocket's height is 12 meters at time t = 0.4 seconds.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A model rocket is launched with an initial upward velocity of 35 m/s.
The rocket's height h (in meters) after t seconds is h=35t-5t
We have to find the time(s) when the rocket's height is 12 meters, we need to solve the equation:
h = 35t - 5t = 30t
We want to find all values of t that make h = 12. So we set h = 12 and solve for t:
12 = 30t
Divide both sides by 30
t = 12/30
t = 0.4
Therefore, the rocket's height is 12 meters at time t = 0.4 seconds.

what is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations? (round your answer to three decimal places.)
0.003 is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations
To calculate the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations.The mean is the expected number of calls involving a fax transmission, while the standard deviation is the measure of variability in the distribution. We then use this information to calculate the probability of exceeding the expected number by more than 2 standard deviations, which can be done using the z-score formula. The z-score for values more than 2 standard deviations away from the mean is 2.33, which corresponds to a probability of 0.003. Thus, the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations is 0.003.

The annual percentage yield is 4.835%. Mabel Causino has $35,000 to invest in a certificate of deposit for 4 years. The CD earns 4.75% interest compounded daily.
Define annual percentage.An annual percentage rate, or APR, is a figure that expresses the entire cost of borrowing money as a proportion of the loan's principle. An accurate picture of how much it costs to borrow money is intended to be provided by the APR on a loan or credit card.
Given
Mabel Causino has $35,000 to invest in a certificate of deposit for 4 years. The CD earns 4.75% interest
compounded daily.
1.048353
The table on page A14 shows the cost per $1.00 (over the course of a year).
$35,000×1.048353=$36,692.36
The sum of the initial principle and the amount per $1.00 is the amount (for a year).
$36,692.36−$35,000=$1,692.36
The difference between the amount (for one year) and the initial principal is the interest (for one year).
$1,692.36÷$35,000
=0.04835
=4.835%
The interest (for a year) divided by the initial principle results in the annual percentage yield.

What is the equation of the line that passes through the point (8, 6) and has a slope
of o?
Answer:
y=6
Step-by-step explanation:
The equation of a line in slope-intercept form is given by:
y = mx + b
where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis. In this case, we are given that the line passes through the point (8, 6) and has a slope of 0, so we can plug these values into the equation to find the equation of the line.
Since the slope of the line is 0, the equation of the line becomes:
y = 0x + b
To find the value of b, we need to plug in the coordinates of the point (8, 6) into the equation and solve for b. This gives us:
6 = 0 * 8 + b
b = 6
Therefore, the equation of the line is given by:
y = 0x + 6
This equation tells us that the y-coordinate of any point on the line is always 6, regardless of the x-coordinate of the point. This means that the line is horizontal and passes through the point (8, 6).
what is the probability that the number of systems sold is within 1 standard deviation of its mean value?
The probability that now the number of sold will not deviate more than 1 standard deviation from the average is 0.74.
Explain the term Discrete Variable?The term "discrete variable" refers to a variable that has a finite range of possible values. such as using only integer numbers. For instance, the total number of students in a class, the quantity of faulty goods in a batch, etc.The given data is
x 1 2 3 4 5 6 7 8
p(x) 0.04 0.10 0.13 0.30 0.31 0.10 0.01 0.01
(a) calculate mean value of x:
μ = E(x)
= ∑(xi.P(xi))
= 4.13
(b) calculate variance of x:
σ² = ∑(xi - E(x))².P(xi)
= 1.81331
(c) calculate standard deviation of x:
σ = √σ²
σ = √1.831
σ = 1.3539
The likelihood that the quantity of systems sold will be within one standard deviation of the its mean:
P(μ - σ < x < μ + σ ) = P(4.13 - 13539 < x < 4.13 + 1.3539)
= P(2.7761 < x < 5.4839)
= P(x = 3) + P(x = 4) + P(x = 5)

The company will be producing 500 units per day in 4 years.
Latanya needs to order some new supplies for the restaurant where she works. The restaurant needs at least 739 glasses. There are currently 390 glasses. If each set on sale contains 6 glasses, which inequality can be used to determine xx, the minimum number of sets of glasses Latanya should buy?
The solution to this inequality is x >= 58. This means that Latanya should buy at least 58 sets of glasses in order to have at least 739 glasses.
What is the inequality equation?
Equations and inequalities are mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are supposed to be equal and shown by the symbol =. Whereas in inequality, the two expressions are not necessarily equal and are indicated by the symbols: >, <, ≤, or ≥.
To determine the minimum number of sets of glasses that Latanya should buy, we can set up the following inequality:
x * 6 + 390 >= 739
This inequality states that the number of glasses Latanya has after buying x sets of glasses should be greater than or equal to the minimum number of glasses the restaurant needs.
To solve for x, we can subtract 390 from both sides of the inequality to get:
x * 6 >= 739 - 390
x * 6 >= 349
x >= 349/6
x >= 58.16
x >= 58
Hence, The solution to this inequality is x >= 58. This means that Latanya should buy at least 58 sets of glasses in order to have at least 739 glasses.

The ratio of red marble to blue marble in a bag is 3:4. If there are 42 marble in the bag,There would be 30 red marbles in the bag.
Red and blue marbles are distributed in a 3:4 ratio.This means that for every 4 blue marbles, there are 3 red marbles.
If we divide 42 (the total number of marbles in the bag) by 4, we get 10.5. This tells us that if there are 4 blue marbles, there are 10.5 red marbles. We can't have a fraction of a marble, so we round down to 10.
