Two bonds are available on the market as follows: Bond 1: Face value $250, 5 years to maturity at a simple interest rate of 5%. Bond 2: Face value $350, 3 years to maturity at a simple interest rate of r. Given that both bonds yield the same interest at maturity, calculate r. Round your answer to the nearest hundredth of a percent. Do NOT round until you have calculated your final answer.
Answer:
5.95%
Step-by-step explanation:
Bond 1:
I = 250(.05)5
I = $62.50
Bond 2:
62.5 = 350(3)r
62.5 = 1050r
r = 62.5/1050
r = 5.95%
Answer:
5.95%

what explicit formula describes the pattern of this table
Answer:
y - 6.28 = 3.14( x - 2 )
Step-by-step explanation:
Notice that 6.28 is twice the approximate value of pi: 2(3.14), and that
9.42 is three times pi. We can deduce immediately that the slope of the line passing through (2, 6.28) and (3, 9.42) is 3.14.
Using the point-slope formula for the equation of a straight line, we get:
y - 6.28 = 3.14( x - 2 )

-missing angle-
What do I do?!
Answer:
156°
Step-by-step explanation:
2x + 4 + 24 = 180
2x + 28 = 180
2x = 180 - 28
2x = 152
x = 152 / 2
x = 76
The missing angle
= 2x + 4
= 2 ( 76 ) + 4
= 152 + 4
= 156°

A property that offers a 7.5 percent return on the listing price has a monthly net of $810.
The property is listed at
Answer:
$129,600
Step-by-step explanation:
Given that
The return percentage is 7.5%
And, the monthly net is $810
We need to find the property listed price
Since we assume that the return percentage is on annual basis
So, for monthly, it is
= 7.5% ÷ 12
= 0.625%
Now the property listed price is
= $810 ÷ 0.625%
= $129,600

Answer:

Step-by-step explanation:
C is the longest side which is 35 ye and b is 21 yd. Then you would subtract 21^2 from 35^2 and you would get 784. Then find the square root of 784 and you would get 28 as the answer! Good luck and have a great day or night!
Answer:
28 yards
Step-by-step explanation:
We can use pythagorean theorem to solve this problem; pythagorean theorem is denoted by the formula a^2 + b^2 = c^2. We already have b, as 21 yd and c, as the hypotenuse is 35 yd. We can plug these values into the formula:
a^2 + 21^2 = 35^2
a^2 + 441 = 1225
a^2 = 784
a = 28 yards
A nutritionist suspected that her company's clients had below average cholesterol. They obtained a random sample of 8 clients of the same age and gender. These clients had a mean cholesterol level of xˉ=4.28 mmol/L (millimoles per liter).
To see how likely a sample like this was to happen by random chance alone, the nutritionist performed a simulation. They simulated 60 samples of n=8 cholesterol levels from a normal population with a mean of 4.6 mmol/L and a standard deviation of 0.5 mmol/L (these are generally accepted values for people with the same age and gender of those in the sample). They recorded the mean of the cholesterol levels in each sample. Here are the sample means from their 60 samples:
They want to test H0:μ=4.6 mmol/L vs. Ha:μ<4.6 mmol/L where μ is the mean cholesterol level for all clients like those sampled.
Based on these simulated results, what is the approximate p-value of the test?
Note: The sample result was xˉ=4.28 mmol/L.
Answer:
p-value ≈ 0.05

Answer:
A
Step-by-step explanation:
(12 ÷ ( 7 . 4 − 3 . 6 ) + 8 − 2)
Follow the order of operations, the first thing to do would be the parenthesis.
7.4 - 3.6 = 3.8
So, your answer would be A, Subtract 7 . 4 − 3 . 6.

A middle school coach wrote down the time, in seconds, of her students’ 100-meter dash as shown in the table. Student Time -(seconds … ) Gary 11.9 Rick 12.3 Phillip 13.5 Jorge 12.0 Robert 12.3 Jeremy 16.0 If the slowest time and the fastest time are removed from the data, how does the new mean compare to the mean of the ..
Answer:
D. The mean would decrease as there is less variability in the data.
Step-by-step explanation:
So, let’s find the mean with all of those numbers. First of all we should order them from least to greatest.
11.9, 12.0, 12.3, 12.3, 13.5, 16.0
We add them all up, and get 78! Once we get this total, we must divide it by how many numbers there are! There are six numbers, so 78/6.
78/6 is equal to 13. So the mean for all those numbers is 13.
Now let’s find the mean if we cross out the greatest and least numbers, the greatest number is 16.0, and the least number Is 11.9.
So, our new data set is:
12.0, 12.3, 12.3, 13.5
Add those all up to get 50.1
Divide the total by the numbers we got left, which is 4!
50.1/4 is equal to 12.525.
So the mean of our new data set is 12.525!
So that’s how I got the answer, have a nice day! Please tell me if I’m wrong!

A summation, also called a sum, is the result of arithmetically adding numbers or quantities. 155 is the answer for 5 times the sum of 24 and 7.
What is Sum?A summation, also called a sum, is the result of arithmetically adding numbers or quantities.
Given,
5 times the sum of 24 and 7
Sum is nothing but addition.
When we see the word sum it means we are adding some value with other factor. In the given problem 24 and 7 are added.
Times means multiplication.
We have to convert 5 times the sum of 24 and 7 to expression.
When we see times, it means product or we are multiplying a number with the other number. Here with 5 we are multiplying the sum of 24 and 7.
5×(24+7)
Firstly we calculate value in parenthesis.
twenty four plus seven is thirty one.
5×31
The product of 5 and 31 is 155.
155
Hence 155 is the answer for 5 times the sum of 24 and 7.
