4.Maria tossed a coin three times. She wrote
a list of her possible outcomes. How many
outcomes on her list had at least one Tail?
A. 1
B. 3
C. 7
D. 8
Answer:
(a) 1
Step-by-step explanation:
In each outcome triplet, each flip has a chance to be H or T. Thus, the following describes all the possible outcomes:
HHHHHTHTHHTTTHHTHTTTHTTTWe see that the only option without one tail is the first one, HHH, so the answer is (a) 1.

Find the vertices of the hyperbola. Enter the smallest coordinate first.
Answer:
([-3], [0]), ([3], [0])
Step-by-step explanation:
The given equation of the hyperbola is presented as follows;
[tex]\dfrac{x^2}{9} - \dfrac{y^2}{49} = 1[/tex]
The vertices of an hyperbola (of the form) [tex]\dfrac{x^2}{a^2} - \dfrac{y^2}{b^2} = 1[/tex] are (± a, 0)
The given hyperbola can we presented in a similar form as follows;
[tex]\dfrac{x^2}{9} - \dfrac{y^2}{49} = \dfrac{x^2}{3^2} - \dfrac{y^2}{7^2} = 1[/tex]
Therefore, by comparison, the vertices of the parabola are (± 3, 0), which gives;
The vertices of the parabola are ([-3], [0]), ([3], [0]).

Answer:
x = y = 15[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{30}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2x = 30[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
x = 15[tex]\sqrt{2}[/tex]
The triangle is isosceles (45- 45- 90) , then 2 legs are congruent, so
y = x = 15[tex]\sqrt{2}[/tex]

Which of these tables represents a linear function?
G(x)=3/x find g'(x) a) by using the quotient rule: b) by first rewriting the expression using exponents and then differentiating.
Answer:
a) The quotient rule is:
if: f(x) = 1/g(x)
Then:
[tex]f'(x) = -\frac{1}{(g(x))^2}*g'(x)[/tex]
In this case, we have:
G(x) = 1/x
Then we can write this as:
G(x) = 1/h(x) with h(x) = x, and h'(x) = 1
Using the above rule we get:
G'(x) = -(1/h(x)^2)*h'(x) = -1/x^2
b) For a function like:
f(x) = x^n
we have that:
[tex]f'(x) = n*x^{n - 1}[/tex]
Here we can write G(x) = x^-1
Then we have n = -1
If we use the above rule, we get:
[tex]G'(x) = (-1)*x^{-1-1} = -1*x^{-2} = \frac{-1}{x^2}[/tex]
So we got the same result using both methods.
6. What would be the new coordinates
of point B if it was reflected across the
y-axis?
с
Answer:
(2, -4)Step-by-step explanation:
The rule for the reflection across the y-axis:
(x, y) → (-x, y)Coordinates of B is (-2, -4)
New coordinates of B:
(-2, -4) → (2, -4)Rule
(x,y)=(-x,y)
So
Old coordinate is (-2,-4)

If 8 cents are needed to buy 10 pebbles, how many dollars are needed to buy 205 pebbles?
Answer:
Hello There!!
Step-by-step explanation:
If 8 cents=10 pebbles then do 205 divided by 10 which is 20.5 . So, 8×20.5=164 dollars.
(8×20.5=164) 8 cents=10 (10×20.5=205)
164 dollars=205
Therefore,the answer is 164 dollars.

A tailor needs to make uniforms for 32 students from a piece of cloth. If the length of that piece 45 3/4m and each student requires 1 1/8m, calculate the length of cloth that would be left
Answer:
uniform for 1 student = 1 1/8 = 9/8
uniform 32 students = 32 x 9/8 = 36m
Total cloth = 45 3/4 = 183/4 = 45.75m
Cloth left = 45.75 - 36 = 9.75m i hope that helps
Vikram has a bucket of three different racquetballs, one blue, one black, and one red. He wants to test each ball to see how well they bounce. He reaches into the bucket and removes one ball without looking. He hits the ball against the wall, catches it, and then drops it back into the bucket. He repeats this process twice more, each time choosing a ball without looking.
Part A:
What is the probability that Vikram hits the blue ball, then the black ball, and then the red ball?
Answer:
Part B:
If Vikram does not drop the balls back into the bucket after he hits them, what is the probability that Vikram hits the blue ball, then the black ball, and then the red ball?
Answer:
Answer:
A) 33.3%
B) 50 %
Step-by-step explanation:
A) if there are 3 balls always in the bucket you need to see what one balk represent one ball is 1÷3 which is 0.33 so by knowing that if Vikram drops the ball back into the bucket after the hit there would be a 33 % chance he will chose the same or a different ball in order.
B)if he won't put the ball back in the bucket there will be only 2 balls felt so 1÷2 = 0.5 so there is a 50 % chance of Victor getting the balls in the correct order

Why is 6/5 not equivalent to 3/2
Answer:
It is the first choiceStep-by-step explanation:
[tex] \frac{3 \times 2}{2 \times 2} = \frac{6}{4} \\ \\ \frac{6}{4} \: \: is \: not \: equal \: to \: \: \: \: \frac{6}{5} [/tex]
The ratio 3 / 2 is multiplied by 2 on both the denominator and numerator to get the value 6 / 4, but the denominator part is not equal to 5, hence 6/5 is not equivalent to 3/2, so option A is correct.
What is the ratio?It is the comparison of one quantity with another. For example, if your weight is 30 kg and your father's weight is 90 kg, then the ratio of weight is 1:3.
Given:
6 / 5 and 3 / 2
As you can see the numerator of 3 / 2 is multiplied by 2 to get the value 6, so the denomination should also be multiplied by the number 2,
(3 × 2 ) / (2 × 2)
6 / 4
But the result came as 4 on the numerator,
Thus, 6 / 5 and 3 / 2 are not equivalent.

What is a logarithm?The logarithm is exponentiation's opposite function in mathematics.
This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 100 = 10², the logarithm of 100 in base 10 is 2, or log10 = 2.
