find is a simple interest for a loan where birr 6,000 borrowed and the amount owned after 5 months this is for 7,500 what is the rate
Answers
Interest = Principal * Rate * Time
In this case, the principal (P) is 6,000 birr, the time (T) is 5 months, and the amount owed (A) is 7,500 birr. We need to find the rate (R).
Interest = Amount Owed - Principal
Let's substitute the values into the formula:
Interest = 7,500 - 6,000
Interest = 1,500 birr
Now we can rearrange the formula to solve for the rate:
Rate = Interest / (Principal * Time)
Rate = 1,500 / (6,000 * 5/12)
Rate = 1,500 / (30,000/12)
Rate = 1,500 * 12 / 30,000
Rate = 0.6 or 0.6 * 100 = 60%
Therefore, the rate of interest for the loan is 60%.
When playing baseball, Chad misses on 60% of the pitches he receives. Describe
how to use random digits to simulate the probability that he will get a hit on more
than 2 of every 10 pitches he receives.
Answers
This proportion represents the estimated probability that Chad will get a hit on more than 2 of every 10 pitches he receives.
what is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.
To simulate the probability that Chad will get a hit on more than 2 of every 10 pitches he receives using random digits, follow these steps:
1. Divide the pitches into groups of 10. For each group of 10 pitches, record the number of hits that Chad gets.
2. Generate a random digit between 0 and 9 for each pitch in the group. If the digit is 0, 1, 2, or 3, consider it a hit. If the digit is 4, 5, 6, 7, 8, or 9, consider it a miss. Repeat this process for each group of 10 pitches.
3. Count the number of groups of 10 pitches in which Chad gets more than 2 hits.
4. Repeat steps 2 and 3 a large number of times (for example, 1000 times) to get an estimate of the probability that Chad will get a hit on more than 2 of every 10 pitches he receives.
5. Calculate the proportion of times in which Chad gets more than 2 hits in a group of 10 pitches.
Therefore, this proportion represents the estimated probability that Chad will get a hit on more than 2 of every 10 pitches he receives.

a sample correlation r = .40 indicates a stronger linear relationship than r = -.60.
Answers
The magnitude of the correlation coefficient, regardless of the sign, provides information about the strength of the linear relationship between variables.
The sample correlation coefficient, r, ranges between -1 and 1. A value of 1 or -1 indicates a perfect linear relationship, where all data points lie precisely on a straight line. On the other hand, a value close to 0 indicates a weak or no linear relationship.
In the given scenario, r = .40 indicates a moderate positive linear relationship. Although the correlation is not perfect (not equal to 1), it still suggests a moderate degree of association between the variables. The positive sign indicates that as one variable increases, the other tends to increase as well, but not necessarily in a strictly linear fashion.
On the other hand, r = -.60 indicates a stronger linear relationship, albeit in the negative direction. The negative sign signifies an inverse relationship, meaning that as one variable increases, the other tends to decrease, but again, not necessarily in a perfectly linear manner. The magnitude, which is the absolute value of the correlation coefficient, indicates a stronger relationship compared to r = .40.
Therefore, it is important to consider both the magnitude and the sign of the correlation coefficient to assess the strength and direction of the linear relationship between variables.

Angelica uses the points (4,3) to represent the location of her house and use the point (10,8) to represent the location of a gas station. This unit on the graph represents 1 mi. Use Pythagorean theorem to determine how far the gas station is from Angelica’s house show your work.
Answers
Answer:
Angelica’s house is 7.81 miles from the gas station
Step-by-step explanation:
By pythogorean theorem, AG² = AP² + GP²
A (4,3), G(10,8), P(10,3)
Since AP lies along the x axis, the distance is calculated using the x coordinates of A and P
AP = 10 - 4 = 6
GP lies along the y axis, so the distance is calculated using the y coordinates of G and P
GP = 8 - 3 = 5
AG² = 6² + 5²
= 36 + 25
AG² = 61
AG = √61
AG = 7.81

\(7x+35=3x-24\)Substract 35 from both sides of the equation:
\(7x+35-35=3x-24-35\)Solve the additions 35-35 and -24-35:
\(7x=3x-59\)Substract 3x from both sides of the equation:
\(7x-3x=3x-59-3x\)Add like terms in both sides of the equation:
\(4x=-59\)Divide both sides of the equation by 4:
\(\frac{4x}{4}=\frac{-59}{4}\)Simplify the fraction 4/4:

The solution to the equation is y = 1/6
Given data:
To find the value of y in the solution of the system of equations:
10x + 24y = 9 ...(1)
8x + 60y = 14 ...(2)
We can use the method of substitution or elimination to solve the system. Let's use the method of substitution:
From equation (1), isolate x:
10x = 9 - 24y
x = (9 - 24y)/10
Now substitute this value of x into equation (2):
8((9 - 24y)/10) + 60y = 14
Simplify and solve for y:
(72 - 192y)/10 + 60y = 14
72 - 192y + 600y = 140
408y = 68
y = 68/408
y = 1/6

Answers
The two polygons are similar using the SAS criteria.
What are polygons?A two-dimensional geometric shape with a finite number of sides is called a polygon. A polygon's sides are constructed from segments of straight lines joined end to end. A polygon's line segments are therefore referred to as its sides or edges. The vertex or corners made by two line segments are where an angle is created. A triangle with three sides is an illustration of a polygon. A circle is a planar figure as well, but since it is curved and lacks sides and angles, it is not regarded as a polygon. Hence, we may argue that while all two-dimensional forms are polygons, not all two-dimensional figures are polygons.
For the given polygons we find the scale factor to determine whether the two figures are similar.
The scale factor is given as:
SF = length of original/ length of new image
SF = 4 / 6
SF = 2/3
For the second segment:
SF = 6/9
SF = 2/3
The ratios of the segment are same. Also the angle between the corresponding segments is 86 degrees.

From the given information:
Two rectangles have the exact same area.The measurements of the first rectangle is 3k by 3 and the measurements of the second rectangle is k+3 by 6.
Then
The area of the first rectangle = 3k*3
The area of the first rectangle = 9k
And
The area of the second rectangle = 6(k+3)
The area of the second rectangle = 6k+18
Then
Compare the both values of the area
6k+18 = 9k
