three coins are flipped .
What is the possibilty that all are tails
Answer:
The third coin also has a 1 in 2 or 1 2 chance of matching the coin on the first toss. Therefore the probability of tossing three coins and getting all heads or all tails is: 1 × 1 2 × 1 2 = 1 4 = 0.25 or 25% We can also show this from the results table below: There are 8 possible outcomes for tossing three coins.

Select all of the properties that a parallelogram that is not a rectangle has. A. 2 pairs of parallel sides B. exactly 1 pair of sides with equal length C. 4 right angles D. 2 acute angles, 2 obtuse angles E. exactly 1 pair of parallel sides
Answer and Explanation:
B, because a rectangle has 2 pairs.
Theoretically, D could also be correct, but not in every scenario; all rectangles are parallelograms, but not all parallelograms are rectangles.

A shelf contains 3 fashion magazines and 4 health magazines. You randomly choose one to read, set it aside, and randomly choose another for your friend to read. Which of the following describes the error in finding the probability that both events $A$ and $B$ occur? Event $A:$ The first magazine is fashion. Event $B:$ The second magazine is health.
Answer:
B
Step-by-step explanation:
The probability of getting both fashion and health magazine without replacement is 2/7.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, a shelf contains 3 fashion magazines and 4 health magazines.
Total number of books = 7
Number of fashion magazines = 3
Number of health magazines= 4
Probability of getting fashion magazines = 3/7
Probability of getting health magazines = 4/6
Probability of getting both the events = 3/7 ×4/6
= 1/7 ×4/2
= 2/7
Therefore, probability of getting both fashion and health magazine without replacement is 2/7.

. If the amount of the loan was
$

, what is the amount of interest she had to pay?
Answer:
57.02 dollars
Step-by-step explanation:
850 * 14/12 * .0575 =
The required, Jordan had to pay $53.03 in interest on her loan.
What is simple interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.
here,
To find the amount of interest Jordan had to pay, we can use the simple interest formula,
I = P × r × t
Where I is the amount of interest, P is the principal (the initial amount of the loan), r is the annual interest rate as a decimal, and t is the time in years.
In this case, P = $850, r = 0.0575 (5.75% expressed as a decimal), and t = 14/12 (since the loan was for 14 months, which is 1 year and 2 months or 1.16667 years).
Substitute the value in equation 1.
I = $850 × 0.0575 × 14/12
= $57.02
Therefore, Jordan had to pay $53.03 in interest on her loan.

Enter the coordinates of the
point on the unit circle at the
given angle.
-225°
Answer:
Step-by-step explanation:
hello :
the coordinates of the point on the unit circle at the given angle.-225°:
x= cos(-225°)= -√2/2
y = sin (-225°)= √2/2
The coordinates of the point on the unit circle at an angle -225°° are [tex](\frac{-\sqrt{2} }{2} , \frac{\sqrt{2}} {2} )[/tex].
What are coordinates of the point?" The coordinates of the point is defined as the pair of such points which represents the exact location of the point."
What is unit circle?" Unit circle means a circle with radius equals to 1unit."
Formula used
Equation of the circle with center (0, 0) and radius r
[tex]x^{2} +y^{2} =r^{2}[/tex]
Coordinates of the point on the circle (rcosθ , rsinθ)
cos(-θ) = cosθ
sin (-θ) = -sinθ
cos ([tex]\frac{3\pi }{2}[/tex] -θ) = -cosθ
sin ([tex]\frac{3\pi }{2}[/tex] -θ) = -sinθ
According to the question,
Given θ = -225°
Unit circle 'r' = 1
Therefore Coordinates are,
'x' coordinates represented by rcosθ
'y' coordinates represented by rsinθ
Substitute the value of r and θ in the coordinates of the point we get,
x = rcosθ
= 1 × cos (-225°)
= cos (225°)
= cos ( 270° - 45°)
[tex]=cos(\frac{3\pi }{2} -\frac{\pi }{4} )[/tex]
[tex]= - sin(\frac{\pi }{4}) \\= - \frac{1}{\sqrt{2} } \\=-\frac{\sqrt{2} }{2}[/tex]
y = rsinθ
= 1 × sin (-225°)
= -sin (225°)
= -sin ( 270° - 45°)
[tex]=-sin(\frac{3\pi }{2} -\frac{\pi }{4} )[/tex]
[tex]= -( - cos(\frac{\pi }{4})) \\= \frac{1}{\sqrt{2} } \\=\frac{\sqrt{2} }{2}[/tex]
Hence, coordinates of the point on the unit circle at an angle -225°° are [tex](\frac{-\sqrt{2} }{2} , \frac{\sqrt{2}} {2} )[/tex].

Suppose that a cylinder has a radius of r units, and that the height of the cylinder is also r units. The lateral area of the cylinder is 882 π square units. Find the value of r.
Answer:
21 units²
Step-by-step explanation:
the area of a circle is
pi×r²
the lateral area of a cylinder is the area only if the "mantle" of the cylinder : the round area all around the cylinder in its side.
in other words : everything but the ground and the top area.
how can we get the area of the side "mantle" ?
we can imagine, we take a knife and cut a straight line (and at 90°) from the top to the bottom, and then cut off the ground and the top circles by cutting along their circumference.
what do we get ?
if we put that remaining area in the table and press it flat, it is ... a rectangle. simply a rectangle.
its width is the height of the cylinder (the length of our initial top-bottom cut).
and its length is the length of the circle circumference that e just cut off.
and the circumference of a circle is
2×pi×r
so, the lateral area of the cylinder is
2×pi×r × h
r being the radius
h being the height of the cylinder.
and we get
LA = 2×pi×r×r = 882×pi
pi × r² = 441 × pi
r² = 441
r = 21 units²

Solve for x: 4(2x -1) + 8 -14x = -8x + 4 + 2x
Answer:
The value of x is all real numbers.
Step-by-step explanation:
4(2x -1) + 8 -14x = -8x + 4 + 2x <== distribute 4
4(2x) + 4(-1) + 8 -14x = -8x + 4 + 2x
8x - 4 + 8 -14x = -8x + 4 + 2x <== combine any like terms on both sides
-6x + 4 = -6x + 4 <== both sides are equal
Since both sides of the equation are equal, this means that any x value makes the equation true. Any real number can be used as the value of x.

What is an equation of the line that passes through the points (-8, 1) and (7, 1)
ANSWER: y = 1
STEPS:
first, find the slope by using the formula
which is also represented as m
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
where from point (-8, 1) x1 is -8 and y1 is 1
then from point (7, 1) x2 is 7 and y2 is 1
so we substitute into the formula
[tex] \frac{1 - 1}{7 - ( - 8)} = \frac{0}{7 + 8} = \frac{0}{15} [/tex]
[tex]m = \frac{0}{15} [/tex]
Then we solve for the equation of the line by using the formula
[tex](y - y1) = m(x - x1)[/tex]
but we have only y1, m and x1 so we substitute given us
[tex](y - 1) = \frac{0}{15} (x - ( - 8))[/tex]
but also, we must get rid of the fraction 0/15
so we multiply through by the denominator 15
[tex]15 \times (y - 1) = 15 \times \frac{0}{15} (x - (8))[/tex]
we get
[tex]15(y - 1) = 0(x - ( - 8))[/tex]
now we expand all brackets
[tex]15y - 15 = 0[/tex]
but we want the equation so we make y stand alone
[tex]15y = 15 \\ \\ \frac{15y}{15} = \frac{15}{15} \\ \\ y = 1[/tex]
the equation of the line is y=1
