When rolling a single number cube, what are the odds, in simplest form, in favor of rolling a 4 or a 5?
A. 1:1
B. 1:2
C. 1:3
D. 1:5
Answer:
C
Step-by-step explanation:
You have a total of 6 outcomes (1,2,3,4,5,6). That is your numerator. Out of those numbers, you only want 2 of them (4 or 5), so the fractions would be 2/6 or 1/3 which can also be written 1:3
Maria buys some soft drinks for her friends. she buys a total of 13 drinks for a total of $32. if medium drinks, m, cost $3 and small, s, drinks $2, write a system of equations which can be used to find how many small drinks and medium drinks she bought.
The total number of small drinks 's' bought by Maria is 7.
The total number of medium drinks 'm' drinks bought by Maria is 6.
What is system of linear equations?A collection of one or more linear equations containing the same variables is known as a system of linear equations (or linear system).
Formation of the linear equation for the drinks bought by Maria:
The total number of drinks bought by the Maria is 13.
Lets say 'm' represents the number of medium drink.
's' represents the number of small drink.
Total drinks comprises of medium drinks and small drinks.
Thus,
s + m = 13, is the first linear equation.
Now medium drinks cost $3.
Total cost for purchasing medium drinks = (price of one medium drink)×(total number of medium drinks)
Total price for medium drinks = 3×m
Similarly,
Total cost for purchasing small drinks = (price of one small drink)×(total number of small drinks)
Total price for small drinks = 2×s
Total cost = total cost of medium drink + total cost of small drink
32 = 3×m + 2×s, is second linear equation.
From equation first substitute the value of 'm' in second equation to fine the total number of drink.
32 = 3×(13 - s) + 2×s
32 = 39 - 3s + 22
s = 7
Put s = 7 in first equation and calculate 'm'.
m = 13 -7
m = 6
Therefore, The total number of small drinks 's' bought by Maria is 7.
The total number of medium drinks 'm' drinks bought by Maria is 6.

I was born on saturday. got marries the 10,000 day of my life. what day of the week is it?
Answer:
Tuesday
Step-by-step explanation:
Days of the week repeat every seven days, so Saturday is day (1+7n) for some integer n.
Number of weeksThe value of n that makes the day number just under 10,000 is ...
1 +7n ≤ 10000
7n ≤ 9999
n ≤ 1428 3/7
Day of the weekSo, Day 1 +1428·7 = 9997 is Saturday. Day 10,000 is 3 days later. That makes Day 10,000 a Tuesday.

I WILL GIVE BRAINLY A dairy farmer wants to mix a 60% protein supplement and a standard 20% protein ration to make 1400 pounds of a high-grade 40% protein ration. How many pounds of each should he use?
The number of pounds of 60% protein and 20% protein supplement used is 700 and 700 pounds respectively.
Simultaneous equationlet
Pounds of 60% protein used = xPounds of 20% protein used = yx + y = 1400
0.60x + 0.20y = 1400×0.40
0.60x + 0.20y = 560
From (1)
x + y = 1400
x = 1400 - y
Substitute into (2)
0.60x + 0.20y = 560
0.60(1400 - y) + 0.20y = 560
840 - 0.60y + 0.20y = 560
- 0.60y + 0.20y = 560 - 840
-0.40y = -280
y = -280/-0.40
y = 700 pounds
Recall,
x + y = 1400
x + 700 = 1400
x = 1400 - 700

A set of 5 numbers has an average of 50. The largest element in the set is 5 greater than 3 times the smallest element in the set. If the median of the set equals the mean, what is the largest possible value in the set
Answer:
5×3=15
15×3=45
therefore the largest value is 45
The largest possible value in the set is 92. The set has an equal mean and median. So, the set is {29, 29, 50, 50, 92}.
What are the mean and median of a set of data?Mean:
For a set of data, the average of all the data values is said to be its mean.
Median:
When the set is arranged in ascending order, the middle term is said to be its median (if there are an odd number of data values in the set) or the average value of the two middle terms is the median (if there are an even number of data values in the set).
Calculation:It is given that,
there are 5 numbers in the set
Mean = 50 and Median = Mean
So, Median = 50
Since there are 5 numbers in the set (odd number), the median is the third(middle) number.
Consider the first or smallest number as 's'.
Then the largest number = 3s + 5
By minimizing each term we get,
first term = s
second term = s
third term = 50
fourth term = 50
fifth term = 3s+5
If the mean is 50, then the sum of all the terms = 50 × 5 = 250
So,
s + s + 50 + 50 + 3s + 5 = 250
⇒ 5s + 105 = 250
⇒ 5s = 145
∴ s = 29
Thus, the smallest number is 29
Then, the largest number = 3s + 5 = 3 × 29 + 5 = 92
Therefore, the largest number in the given set is 92.

Line segment Z E is the angle bisector of AngleYEX and the perpendicular bisector of Line segment G F. Line segment G X is the angle bisector of AngleYGZ and the perpendicular bisector of Line segment E F. Line segment F Y is the angle bisector of AngleZFX and the perpendicular bisector of Line segment E G. Point A is the intersection of Line segment E Z, Line segment G X, and Line segment F Y.
Triangle G E F has angles with different measures. Point A is at the center. Lines are drawn from the points of the triangle to point A. Lines are drawn from point A to the sides of the triangle to form right angles and line segments A X, A Z, and A Y.
Which must be true?
Point A is the center of the circle that passes through points E, F, and G but is not the center of the circle that passes through points X, Y, and Z.
Point A is the center of the circle that passes through points X, Y, and Z but is not the center of the circle that passes through points E, F, and G.
Point A is the center of the circle that passes through points E, F, and G and the center of the circle that passes through points X, Y, and Z.
Point A is not necessarily the center of the circle that passes through points E, F, and G or the center of the circle that passes through points X, Y, and Z
The correct option that depicts the centroid of the triangle is; C. Point A is the center of the circle that passes that passes through the points E, F and G and is the center of the circle that passes through the points X, Y and Z.
How to interpret the segments formed from Triangle Centroid?The center of inscribed circle into the triangle is the point where the angle bisectors of the triangle meet.
The center of the circumscribed circle over the triangle is the point where the perpendicular bisectors of the sides meet.
Line segments ZE, FY and GX are both angle bisectors and perpendicular bisectors of the sides. Thus, the point of intersection of line segments ZE, FY and GX is the center of inscribed circle into the triangle and the center of the circumscribed circle over the triangle.
Inscribed circle passes through the points X, Y and Z. Circumscribed circle passes through the points E, F and G. So, point A is the center of the circle that passes that passes through the points E, F and G and is the center of the circle that passes through the points X, Y and Z.
Thus, the correct option is option C. Point A is the center of the circle that passes that passes through the points E, F and G and is the center of the circle that passes through the points X, Y and Z.

There were only 86 confirmed cases of Measles in the year 2000. In 2019, there was a reported 1,350 % increase in confirmed
cases of Measles. How many cases were there in 2019?
Answer:
1161 confirmed cases
Step-by-step explanation:
In 2000 the number of cases was 86
Percent means out of a hundred, so if we divide 1350 by 100 we get 13.5.
So, we must multiply 13.5 and 86 to get the amount of cases in 2019.
13.5*86 = 1161 confirmed cases in 2019

What lifetime value (in hours) is such that the total lifetime of all batteries in a package exceeds that value for only 5% of all packages
The lifetime of the batteries in a package is 14.31 hours which exceeds that value for only 5% of all packages.
Give sample mean of 13 hours and standard deviation of 1 hour and sample size is 9.
We have to apply t test in this because the value of n which is sample size is less than 30.
We have been given the p value of the required mean so we have to find the t value for this with degree of freedom (9-1)=8
t value=2.306.
We know that
t=X bar-μ/s/[tex]\sqrt{n}[/tex]
s/[tex]\sqrt{n}[/tex]=1/[tex]\sqrt{3}[/tex]=0.57
Put all the values in the above formula to calculate required mean.

The country is 3250 miles in distance from east to west, and 3400 miles from north to south.
Given Information
It is given that,
The distance of the country on map from east to west, l = 65 inches
The distance of the country on map from north to south, b = 68 inches
As per the given scaling of map, 1 inch = 50 miles
How large is the actual country?
Thus, the actual distance from east to west, L = l × 50 miles
L = 65 × 50 miles
L = 3250 miles
The actual distance from north to south, B = b × 50 miles
B = 68 × 50 miles
