Answer:
D
Step-by-step explanation:
With each flip of the coin, the chance of it landing on tails is multiplied by half. Hence the chance of landing a consecutive series of tails decreases the more times you flip the coin, but never reaches 0.
A is incorrect as it is possible to land heads on any flip.
B is incorrect as there is always a possibility of landing tails on every flip.
C is incorrect as the chance of getting tails on every flip is small (and gets smaller) and hence cannot be considered to be likely.
Hence D is the answer.
Given that a = 14 cm and b = 25 cm, work out the area of the triangle.
Answer:
175
Step-by-step explanation:
I am assuming that you mean that a and b are both bases of a right triangle. Please correct me if I am wrong.
14 * 25/2 = 350/2 = 175
The area would then be 175 cm²

What is the meaning of f '' (4) = -4?
Hi there!
f''(4) = -4 means that at x = 4, the second derivative is equal to -4. This is equivalent to the instantaneous rate of change of the graph of f'(x) at x = 4 as well.
Answer:
Step-by-step explanation:
if the second derivative is -4 means that the function is concave down and that at point 4 the function has a maximum

The horizontal cross section shown is a parallel to the base of the pyramid is the shortest side of the cross-section measures 1.2 cm what is the measure of the cross
Answer:
The longest side of the cross-section is: [tex]2.4cm[/tex]
Step-by-step explanation:
Given
See attachment for pyramid
Required
The longest side of the cross-section
The base of the pyramid is a rectangle with the following dimension (in terms of length)
[tex]Long = 6cm[/tex]
[tex]Short = 3cm[/tex]
For the cross-section, we have:
[tex]Long = x[/tex]
[tex]Short =1.2cm[/tex]
Since both are parallel, then the following relationship exist between both
[tex]Ratio = Long : Short[/tex]
So, we have:
[tex]6cm : 3cm = x: 1.2cm[/tex]
Express as fraction
[tex]\frac{6cm }{ 3cm }= \frac{x}{1.2cm}[/tex]
[tex]2= \frac{x}{1.2cm}[/tex]
Make x the subject
[tex]x = 2 * 1.2cm[/tex]
[tex]x = 2.4cm[/tex]

What is the area of the right triangle shown below?
Answer:
1.5
Step-by-step explanation:
base x height x 0.5
Pythagorean theorem: c^2 - a^2 = b^2
b = square root of (2.5)^2 - (1.5)^2
= 2
b = height
area = 0.5 x 1.5 x 2 = 1.5
Answer:
1.5
Step-by-step explanation:
Use the Pythagorean Theorem. A^2 + b^2 = c^2
A and b being the sides and C being the hypotenuse.
2.5^2 - 1.5^2 = 4
Square root of 4 is 2.
Then you use the area of a triangle formula. 1/2 * base * height = Area of a triangle.
1.5 * 2 * 0.5 = 1.5
Jane is buying a jacket that regularly costs $54. However, the jacket is on sale for 25% off the regular price. A sales tax of 6% will be added to the final purchase price. How much will Jane pay for the jacket, including tax?
Answer:
42.93
Step-by-step explanation:
54 x 0.25 = 13.50
54 - 13.5 = 40.50
40.5 x 0.06 = 2.43
40.50 + 2.43 = 42.93
Answer:
$42.93 I received 100%
Step-by-step explanation:
A circle centered at the origin has a radius of 13. The terminal side of an angle x, intercepts the circle in quadrant IV at point C. The x coordinate of point C is 12. What is the value of sin x
Answer:
[tex]sin x=-\frac{5}{13}[/tex]
Step-by-step explanation:
From the question we are told that:
Radius [tex]r=13[/tex]
Co-ordinate of x axis at C [tex]x'=12[/tex]
Let
x' represent the x axis
y' represent the y axis
Since the intercept across the radius has values on the x' and y' axis
Therefore
Generally the Trigonometric equation for cos x is mathematically given by
[tex]cos x=\frac{x'_c}{r}[/tex]
[tex]cos x=\frac{12}{13}[/tex]
Generally the Trigonometric equation for sin x is mathematically given by
[tex]sin x=\sqrt{1-cos^2x}[/tex]
[tex]sin x=\sqrt{1-(\frac{12}{13})^2}[/tex]
[tex]sin x=\frac{5}{13}[/tex]
Since x is in the IV quadrant sin x is negative
[tex]sin x=-\frac{5}{13}[/tex]
2x-56=34 solve for x
Answer:
x = 45
Step-by-step explanation:
2x - 56 = 34
2x = 34 + 56
2x = 90
x = 45
Answer:
x = 45
Step-by-step explanation:
2x-56=34 add 56 to both sides
2x = 90 divide both sides by 2
x = 45

Answer:
The probability of getting a 1, 2, 3 on three rolls respectively is [tex]\frac{1}{216}[/tex].
Step-by-step explanation:
Since you are rolling three dies, and each die has six sides, that means there are a total of 216 possible outcomes. Out of the 216 different outcomes, only 1 of them meet the requirement of rolling a '1' on the first die, a '2' on the second die, and a '3' on the third die, so the fraction to represent the situation would be [tex]\frac{1}{216}[/tex].
