You roll 2 fair 6-sided dice. What is the probability of rolling a sum of 7 or more?
18/36 or 1/2
20/36 or 5/9
19/39
21/36 or 7/12
Answer:
here we have rolled two dice. So total no. of possible outcomes will be 6^2=36. These are (1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).
Now, among these cases the cases where the sum is seven for (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) i.e. there are 6 cases.
Now, it is time to calculate the probability.
The required probability is,
p = (No. of cases favorable for the event)/(Total no. of cases)
=6/36 =

Answer:
for the first one : 0.91 or 0.916 either one
for the second answer : 1 11/20
Step-by-step explanation:
Here is the explanation for the second question>>>To find the total of 3/4 and 4/5 is to add them together. However, in order to add them together you need to find the least common denominator (LCD). And the LCD of both denominators would be 20, because that is the smallest number both 4 and 5 can divide into. And here is the tricky part, now you have to change the numerators. So since 3/4th's now has a denominator of 20 you have to make the 3 match the 20. So 4 times what it 20? It is 5. So now multiply 5 by three and that will give you 15/20, which can reduce to 3/4 which means that you did this correctly! Now repeat the same steps with 4/5:
4/5=4/20
20÷5=4
4•4=16
16/20 (16/20 can reduce to 4/5 which means you did this correctly.
Now to add them keep the denominators the same and only add the numerators:
15/20 + 16/20 = 31/20
Now this as a mixed number would be 1 11/20. I hope this was helpful!
Answer:
1.) 1 1/12
2.) 1 11/20
Step-by-step explanation:
5/6+1/4
convert to common denominators
5/6 x 2/2 = 10/12
1/4 x 3/3 = 3/12
10/12+3/12=13/12
Convert to a mixed number
1 1/12
3/4+4/5
convert to common denominators
3/4 x 5/5 = 15/20
4/5 x 4/4 = 16/20
15/20+16/20=31/20
Convert to a mixed number
1 11/20

<PQR = 90° ( inscribed angle in semi circle)
Now
<QPR + <PQR + <PRQ = 180° { being sum of angles of triangle)
39° + 90° + <PRQ = 180°
<PRQ = 180° - 39° - 90°

Edith purchased a stove for $950. It depreciates about 0.7% each year. What is the value of the stove after six years?
A. $946.68
B. $943.35
C. $910.79
D. $990.60
Answer:
C
Step-by-step explanation:
Beause it still retains %99.3 of it's value we can write the following equation
950(.993)^x
where x is years
950(.993)^6=910.7918=C
In a sports meet, Sonam's team completes the run at 40 seconds during heat events. On championship day, his team completes the same run at 45 seconds. What is the percentage difference in the completion time from the best completion time? A. 10.5% B. 12.5 % C. 15.5 % D. 20.5 %
Answer: B. 12.5 %
Step-by-step explanation:
GIven: Best completion time = 40 seconds
completion time of other members = 45 seconds
The percentage difference in the completion time from the best completion time = [tex]\dfrac{difference}{Best\ completeion\ time}\times100[/tex]
[tex]=\dfrac{45-40}{40}\times100\%\\=\dfrac{5}{40}\times100\%\\\\=12.5\%[/tex]
Hence, the correct option is B. 12.5%.
The percentage difference in the completion time from the best completion time is 12.5%.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is that Sonam's team completes the run at 40 seconds during heat events while on the championship day, his team completes the same run at 45 seconds. Therefore, the difference can be written as,
[tex]\rm Difference =45\ sec -40\ sec=5\ sec[/tex]
Now, as we want to know the percentage difference in the completion time from the best completion time, therefore, we can write,
[tex]\text{Percentage Difference}=\dfrac{\text{Difference}}{\text{Best completion time}} \times 100[/tex]
[tex]=\dfrac{5}{40}\times 100\\\\=12.5\%[/tex]
Hence, the percentage difference in the completion time from the best completion time is 12.5%.

"a circle centered at the origin has a radius of 12. what is the equation of the circle?
Answer:
12 = x^2 + y^2
PLEASE BRAINLIEST?!
The equation of the circle centered at the origin has a radius of 12 is x² + y² - 144 = 0.
What is radius?The circle has a diameter, the whole circumference of the circle, so the radius is the half of the diameter.

Caroline purchased a car four years ago at a price of $28,400. According to research on this make and model, similar cars have straight line depreciated to zero value after 8 years. How much will this car be worth after 51 months from when it was purchased?
Answer:
The car value is $13,312.50
Step-by-step explanation:
Trust me this stuff is easy
The car will be worth $13,312.50 after 51 months from when it was purchased.
What is depreciation?Depreciation is the process of deducting the cost of a business asset over a long period of time, rather than over the course of one year.
Now it is given that,
Price of car during purchase = $28,400
Depreciation Time = 8 years
Straight line depreciated value after 8 years = $0
So, Amount of Depreciation per year = Price of car / Depreciaton Time
⇒ Amount of Depreciation per year = 28,400/8
⇒ Amount of Depreciation per year = $3,550
So, after 51 months i.e. 51/12 years
Amount of Depreciation of car after 51 months = Amount of Depreciation per year x Number of years
⇒ Amount of Depreciation of car after 51 months = 3,550 x 51/12
⇒ Amount of Depreciation of car after 51 months = $15,087.5
So, Cost of car after 51 months = $28,400 - $15,087.5
⇒ Cost of car after 51 months = $13,312.50
Thus, the car will be worth $13,312.50 after 51 months from when it was purchased.

Reflect square JKLM with J(1, 4), K(6, 5), L(7, 0) and M(2, -1) in the y-axis. What are the coordinates of M'?
Given:
Reflect square JKLM with J(1, 4), K(6, 5), L(7, 0) and M(2, -1) in the y-axis.
To find:
The coordinates of M'.
Solution:
We have, M(2, -1) .
If a figure reflected over the y-axis then
[tex](x,y)\to (-x,y)[/tex]
Using this rule, we get
[tex]M(2,-1)\to M'(-2,-1)[/tex]
Therefore, the coordinates of point M' are (-2,-1).
