Answer:
The probability is 1/32
Step-by-step explanation:
What the question asks here is that in a throw of a coin 5 times, what is the probability that we have the head being revealed once in the 5 throws
for a fair coin, we can only get a head or a tail
So the probability of getting a head equals that of getting a tail
Since total probability is 1; then the probability of each will be 1/2
So, we can now have the probability as follows;
1 head (1/2) and 4 tails (1/2 * 1/2 * 1/2 * 1/2)
1/2 * 1/2 * 1/2 * 1/2 * 1/2 = (1/2)^5 = 1/32

Answer:
16 degrees
Step-by-step explanation:
This is a right triangle with shorter leg 3 in and hypotenuse 11 in. The 3 in side is opposite the angle theta. Thus, by definition of the sine function,
sin theta = 3/11 = 0.273
Using a calculator and the inverse sine function, we get theta = 0.276 radian, or 15.8 degrees. This rounds up to 16 degrees.

Answer:
x = 91
Step-by-step explanation:
y = 130
The supplementary angle with y is 50
z = 321
360 - 321 = 39
Interior angles:
50 and 39 and x
To find x:
x + 50 + 39 = 180
x + 89 = 180
x = 180 - 89
x = 91
Add the polynomial expressions using the horizontal format.
(6x3 + 5x) + (4x3 + x2 - 2x + 9)
Answer:
I'll clear the parentheses first. This is easy to do when adding, because there are no "minus" signs to take through any parentheticals. Then I'll group the like terms in accordance to their variables (keeping them in alphabetical order), and finally I'll simplify:
(2x + 5y) + (3x – 2y)
2x + 5y + 3x – 2y
2x + 3x + 5y – 2y
5x + 3y
These two terms are un-like (because they have different variables), so I cannot combine them. This means that I've gone as far as I can, so my hand-in answer is:
5x + 3y

The first cube has a side length of 3 units. The second cube has a side length of 5 units. Write an expression that you can use to find the total volume of ice you can make.
Answer:
152 cubic units
Step-by-step explanation:
Volume of a cube = L³ where;
L is the side length of a cube
For the cube of side length of 3 units
Volume of the cube = 3³
Volume of the cube = 27 cubic units
For the cube of side length of 5 units
Volume of the cube = 5³
Volume of the cube = 125 cubic units
Total volume the ice can make = (125 + 27)cubic units
Total volume the ice can make = 152 cubic units

Your math teacher allows you to choose the most favorable measure of central tendency of your test scores to determine your grade for them. On six tests you earn scores of 89, 81, 85, 82, 89, and 89. What is your grade to the nearest whole number, and which measure of central tendency should you choose
Answer: 89
Step-by-step explanation:
Since the tests scores are 89, 81, 85, 82, 89, and 89. The measure of central tendency are:
Mean = (89 + 81 + 85 + 82 + 89 + 89) / 5
= 515/6
= 85.83
Median = 89, 81, 85, 82, 89, and 89. We'll rearrange the numbers which will be:
81, 82, 85, 89, 89 and 89
Median = 85+89/2
= 174/2
= 87
Mode = 89 which appears most.
Since the math teacher allows me to choose the most favorable measure of central tendency, I'll choose the mode since it gives a higher score.

The seventh-grade class is selling boxes of votive candles as a fundraiser. The first box purchased costs $14.00, and each additional box costs $10.00.
b. An equation that relates the total money spent on boxes of candles, C, to the number of additional boxes purchased, b, is
c. Using the equation from part (b), the total money spent by a person who bought 3 boxes of candles for the fundraiser would be $
Step-by-step explanation:
b. C= 14+(10b)
c. C = 14+ ( 10 x 3) = 14+30 =44
b) The number of additional boxes purchased is C= 14 + 10b
c) The total money spent by a person who bought 3 boxes of candles is $54.
What is Expression?In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is the expression.
Given:
The first box purchased costs $14.00.
Each additional box costs $10.00.
let total money spent on boxes of candles be C then number of boxes purchased
C = 14+ 10 b
and, When b= 3 boxes
C = 14 + 10b
= 14 + 10(3)
= 14+ 30
= 54

What point represents the x- intercept of the graph of the equation y = 3/5x +3/2?
Answer:
(-2.5,0)
Step-by-step explanation:
To find the x intercept you need to set y=0 then solve for x.
y=3/5x + 3/2
0=3/5x + 3/2
-3/2 = 3/5x
x = -2.5
you put in into point form. (-2.5,0)

The ratio of Sara and Laila age was 5:4. 2 years later their ratio is 6:5. What is their current ages?
Sara's age
Answer:
Sara is 10 and Laila is 8Step-by-step explanation:
Sara's age = sLaila's age = lThe ratios:
s/l = 5/4 ⇒ s = 5l/4(s + 2)/(l + 2) = 6/5 ⇒ 5(s + 2) = 6(l + 2) ⇒ 5s = 6l + 2Substitute s into the second equation and solve for l:
5(5l/4) = 6l + 225l = 24l + 8l = 8Fins s:
s = 5*8/4 = 10Multiple choices

12 x 6 = 72 x 4 = 288,
add them up and we get 360.

In the rectagular prism shown below, GH is parallel to EF. If the equation of GH is 6y-x=2, could the equation of EF be 4=y-1/6x? Explain your reasoning.
Answer:
Yes
Step-by-step explanation:
Given
GH:
[tex]-6y - x = 2[/tex]
Required
Can EF be
[tex]4 = y - \frac{1}{6}x[/tex]
First, we determine the slope of GH
[tex]-6y - x = 2[/tex]
Solve for 6y
[tex]6y = -x - 2[/tex]
Solve for y
[tex]y = -\frac{1}{6}x - \frac{2}{6}[/tex]
[tex]y = -\frac{1}{6}x - \frac{1}{3}[/tex]
An equation has the form:
[tex]y =mx + b[/tex]
Where
[tex]m = slope[/tex]
By comparison:
[tex]m = -\frac{1}{6}[/tex]
Next, determine the slope of EF
[tex]4 = y - \frac{1}{6}x[/tex]
Make y the subject
[tex]y = -\frac{1}{6}x + 4[/tex]
The slope is:
[tex]m = -\frac{1}{6}[/tex]
Compare the slopes of both lines.
[tex]m=m = -\frac{1}{6}[/tex]
Since they have the same slopes, then the equation of EF is possible
Show that
[tex] \frac{1}{1 + \frac{1}{ \sqrt{2} } } [/tex]
can be written as
[tex]2 - \sqrt{2} [/tex]
