Sofia's family members are choosing numbers to see in what order they will choose gifts. They will spin a spinner with eight sections. The sections are numbered 1 though 8,and all sections are the same size.
What is the probability of spinning a number greater than 3?
A. 3/8
B. 8/3
C. 5/8
D. 8/5
Answer:
it should be c. 5/8
Step-by-step explanation:
Since the spinner is out of 8 and the probability is asking for above 3, subtract the 3 from the 8, and you get 5/8
im not too sure if this makes sense, or if it works for everything, but it does help with this. Hope i helped :)
Answer:
C. 5/8

A 12 foot ladder is leaning up against the side of a building. The bottom of the ladder is 4 feet away from the bottom of the building Approximately how high up the side of the building does the ladder reach? 8 ft 10 ft 11 ft 12 ft
You can use the Pythagoras theorem for this since a right triangle is formed.
[tex]c^2 = a^2 + b^2[/tex]
C = 12
A = 4
B = x
Input values:
[tex]12^2 = 4^2 + x^2[/tex]
[tex]144 = 16 + x^2[/tex]
[tex]128 = x^2[/tex]
[tex]x = \sqrt{128}[/tex]
[tex]x = 11.3137...[/tex]
So, about 11ft.

Answer:
0.8^4
Step-by-step explanation:
Write the expression using exponents.
[tex]0.8 \: · \: 0.8 \: · \: 0.8 \: · \: 0.8 \: = \boxed { ? }[/tex]
___________________Solution :-Given Information :-Expression ➢ 0.8 · 0.8 · 0.8 · 0.8 To Find :-The value of the expression using exponents. Calculation :-Since, the expression is actually the repetition of 0.8, so we can write this as,
⇒ 0.8 · 0.8 · 0.8 · 0.8 = ( 0.8 )⁴
Calculating further, We get,
⇒ ( 0.8 )⁴ = [tex] \sf \frac{8 \times 8 \times 8 \times 8}{10 \times 10 \times 10 \times 10} = \frac{8⁴}{10⁴} [/tex]
⇒ ( 0.8 )⁴ = [tex] \frac{4096}{10000} [/tex]
Calculating further, We get,
⇒ ( 0.8 )⁴ = 0.4096
∴ 0.8 · 0.8 · 0.8 · 0.8 = ( 0.8 )⁴ = 0.4096
____________________Final Answer :-0.8 · 0.8 · 0.8 · 0.8 = ( 0.8 )⁴ = 0.4096____________________The function y=-x^2+65x+256 models the number y of subscribers to a website, where x is the number of days since the website launched. The number of subscribers to a competitor's website can be modeled by a linear function. The websites have the same number of subscribers on Days 1 and 34. a. Write a linear function that models the number of subscribers to the competitor's website.
Answer:
[tex]y = 30x+290[/tex]
Step-by-step explanation:
Given
[tex]y=-x^2+65x+256[/tex]
Required
The linear function of a competitor's website
On day 1, both websites have the same subscribers.
This implies that:
[tex]y=-x^2+65x+256[/tex]
Substitute: [tex]x =1[/tex]
[tex]y=-(1)^2+65*1+256[/tex]
[tex]y=-1+65+256[/tex]
[tex]y=320[/tex]
This implies:
[tex](x_1,y_1) = (1,320)[/tex]
On day 34, both websites have the same subscribers.
This implies that:
[tex]y=-x^2+65x+256[/tex]
Substitute: [tex]x =34[/tex]
[tex]y=-(34)^2+65*34+256[/tex]
[tex]y=-1156+2210+256[/tex]
[tex]y=1310[/tex]
This implies:
[tex](x_2,y_2) = (34,1310)[/tex]
To calculate the linear function of the competitor, we have:
[tex](x_1,y_1) = (1,320)[/tex]
[tex](x_2,y_2) = (34,1310)[/tex]
Calculate slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
[tex]m = \frac{1310 - 320}{34-1}[/tex]
[tex]m = \frac{990}{33}[/tex]
[tex]m = 30[/tex]
The equation is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y = 30 * (x - 1) + 320[/tex]
Open bracket
[tex]y = 30x - 30 + 320[/tex]
[tex]y = 30x+290[/tex] --- This represents the linear function of the competitor's website
The linear function of the competitor's website is represented by y=30x-290.
We have given that,the function y=-x^2+65x+256 models the number y of subscribers to a website, where x is the number of days since the website launched.
We have to find the linear function of a competitor's website.
For the day 1, both websites have the same subscribers.
This implies that
[tex]y=-x^2+65x+256[/tex]
x represent the value of day
so plug x=1 we get
[tex]y=(-1)^2+65+256[/tex]
[tex]y=-1+65+256\\y=320[/tex]
Therefore we get the point
[tex](x_1,y_1)=(1,320)[/tex]
On day 34, both websites have the same subscribers.
[tex]y=-x^2+65x+256[/tex]
x=34
[tex]y=-(34)^2+65\times 34+256[/tex]
[tex]y=-1156+2210+256\\y=1310[/tex]
[tex](x_2,y_2)=(34,1310)[/tex]
What is the slope point form?[tex](y_2-y_1)=m(x_2-x_1)[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{1310-320}{34-1} \\m=\frac{990}{33} \\m=30[/tex]
Now slope point form is
[tex]y-y_1=m(x-x_1)[/tex]
Theefore we get
[tex]y=30(x-1)+320[/tex]
[tex]y=30x-290[/tex]
Therefore, the linear function of the competitor's website is represented by y=30x-290.

Answer:
10
Step-by-step explanation:
arrange the number in order from smallest to largest, 4, 6, 6, 9, 11, 19, 23, 34. you then find the middle number, in this case there is no middle number, but 9 and 11 are the closest, so you add those to together to get 20, then divide by 2. this gives you ten

Step-by-step explanation:
Median is ordering the numbers from smallest to biggest.
Ordered: 4,6,6,9,11,19,23,34
And there is no middle number so you have two add the two middle numbers 9+11=20 then divide by 2 which equals 10.

Write the sentence as a conditional statement.
Two parallel lines lie in the same plane.
Find X and Y using the image.
Answer:
x = 59°
y = 130°
Step-by-step explanation:
Find x:
Recall: the measure of an inscribed angle = ½(measure of intercepted arc), based in the inscribed angles theorem
Therefore,
x = ½(118°)
x = 59°
Find y:
y = 2(180 - (56 + x)) => inscribed angles theorem
Plug in the value of x
y = 2(180 - (56 + 59))
y = 2(180 - 115)
y = 2(65)
y = 130°
Each month Elizabeth budgets $760 for fix expenses, $620 for living expenses, and $80 for annual expenses. Her annual net income is $35,040. Which sentence best describes her monthly budget.
It shows a Deficit of $1255
It shows a surplus of $1255
It shows a surplus of $1460
It is balanced
Answer:
Step-by-step explanation:
760+620+80=1460 total monthly expenses.
$32,580 annually divided by 12 months = monthly income of $2,715
2,715-1460=1,255
Her budget shows a surplus of $1,255

Use the law of cosines to write an expression equivalent to b
Given:
A triangle ABC.
The given expression for b is:
[tex]b=\sqrt{m+n-pq}[/tex]
To find:
The expression that is equivalent to b.
Solution:
According to the Law of Cosines,
[tex]b^2=a^2+c^2-2ac\cos B[/tex]
It can be written as:
[tex]b=\sqrt{a^2+c^2-2ac\cos B}[/tex] ...(i)
