The rate is given as a percent (%). Before using it in the simple interest formula, you must first convert it to a _____.
fraction
ratio
dollar amount
decimal
Answer:
decimal
Step-by-step explanation:
Before using the rate given as a percentage in simple interest formula, you must first convert it to decimal.
This helps in simplifying the work and help the calculation.
Simple interest = [tex]\frac{PRT}{100}[/tex]
P is the principal
R is the rate
T is the time
The rate is taken to decimal and inserted into the problem.
Before using it in the simple interest formula, you must first convert it to a decimal.
The following information should be considered:
We know that there is four terms i.e. simple interest, Principal, rate of interest, and the time period.Also, SI = (Principal) (Rate) (Time period).Here for rate we have to take it in a decimal form and then insert into the problem.Therefore we can conclude that the last option is correct.

An article published in the Washington Post claims that 45 percent of all Americans have brown eyes. A random sample of =80 college students students found 30 who had brown eyes.
Answer:
a. -1.35
b. 0.177016
Step-by-step explanation:
According to the question, following data is given
Brown eyes american percentage is 45
Random sample be 80 out of which 30 had brown eyes
Based on the above information
The computation is shown below:
a. The proportion of the sample is
[tex]\bar p = \frac{30}{80}\\\\= 0.375[/tex]
The z value is
[tex]z = \frac{\bar p - p }{\sqrt{\frac{p(1 - p)}{n} } } \\\\\frac{0.375-0.45 }{\sqrt{\frac{0.45(1 - 0.45)}{80} } }[/tex]
= -1.35
b Now the P value is
As z comes -1.35
So, there is a two tailed p value i.e. 0.177016

The function f(x) is exponential and the function g(x) is linear, These functions have the following values: f(1) = 2 g(1) - 2.5 f(2)= 6 g(2) = 4 It follows that there must be a solution to f(x) = g(x) between x = 1 and x = 2.
True
False
Answer:
Step-by-step explanation:
There does not exist any solution of as thir graphs do not intersect.
Step-by-step explanation:
We are given that,
The values of the exponential function f(x) are f(1)= 2 and f(2)= 6.
That is, we get,
So, the function f(x) is .
Moreover, the values of the linear function g(x) are g(1) = 2.5 and g(2) = 4.
That is, the slope = = 1.5
Substituting the slope and point (1,2.5) in the linear equation , where m is the slope, we get,
i.e. b= 1
Thus, the function g(x) is .
Consider,
i.e.
Now, the function f(x) is exponentially increasing and the linear function g(x) is increasing between x= 1 and x= 2, but there is no point where the graphs of the functions are intersecting.
Thus, there is no solution of the equation .

In a certain board game a 12 sided number cube showing numbers 1-12 is rolled. If 3 such number cubes are rolled, what is the probability that at least 1 show as a 2?
Answer:
0.2297453
Step-by-step explanation:
Given that :
Total faces of = 12 labeled 1 - 12
Probability of showing a 2 ;
P = required outcome / Total possible outcomes
P(showing a 2) = 1 /12
Hence, probability of not showing a 2 ;
P(showing a 2)' = 1 - 1/2 = 11/12
Probability that atleast one of 3 cubes shows a 2 :
1 - P(none of the cubes shows a 2)
P(none of the cubes shows a 2) =
(11/12 * 11/12 * 11/12) = 0.7702546
1 - 0.7702546 = 0.2297453
This question is based on the probability. Therefore, the probability that at least 1 show as a 2 is 0.22974 if 3 such number cubes are rolled.
Given:
In a certain board game a 12 sided number cube showing numbers 1-12 is rolled.
We need to determined the probability that at least 1 show as a 2, if 3 such number cubes are rolled.
It is given that total faces of = 12 labeled 1 - 12
Now calculating probability of showing a two ;
[tex]Probability = \dfrac{ Required\, outcome }{Total\, possible \,outcomes}[/tex]
[tex]Probability\, of\, showing\,a \,two=\dfrac{1}{12}[/tex]
Hence, probability of not showing a 2 is,
[tex]Probability\, of\, not\,showing\,a \,two=1-\dfrac{1}{12}[/tex]
Now, calculating probability that at least one of 3 cubes shows as a 2 =
1 - P(none of the cubes shows a 2)
[tex]P(none\, of\, the\, cubes\, shows\, a \,2) = \dfrac{11}{12} \times \dfrac{11}{12} \times \dfrac{11}{12} \\\\P(none\, of\, the\, cubes\, shows\, a \,2)=\dfrac{1331}{1728} = 0.770[/tex]
Probability that at least one of 3 cubes shows as a 2 = 1 - 0.770 = 0.22974
Therefore, the probability that at least 1 show as a 2 is 0.22974 if 3 such number cubes are rolled.

Which geometric series results in a sum of -69,905
Using geometric sequence concepts, it is found that the one which results in a sum of -69,905 is:
D. [tex]\sum_{k = 0}^{9} -\frac{1}{5}(4)^k[/tex]
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.As a sum, it can be represented by:
[tex]\sum_{k = 0}^{n - 1} a_1(q)^k[/tex]
In which [tex]a_1[/tex] is the first term.The result of the sum is:
[tex]S = \frac{a_1(1 - q^n)}{1 - q}[/tex]
Item A:
For this sequence, we have that:
[tex]a_1 = \frac{1}{4} = 0.25, n = 8, q = -5[/tex]
Hence, the sum is:
[tex]S = \frac{0.25(1 - (-5)^8)}{4} = -24414[/tex]
Item B:
For this sequence, we have that:
[tex]a_1 = -\frac{1}{4} = -0.25, n = 12, q = 5[/tex]
Hence, the sum is:
[tex]S = \frac{-0.25(1 - (5)^12)}{-4} = -15258789[/tex]
Item C:
For this sequence, we have that:
[tex]a_1 = \frac{1}{5} = 0.2, n = 11, q = -4[/tex]
Hence, the sum is:
[tex]S = \frac{0.2(1 - (-4)^11)}{3} = 279620.3[/tex]
Item D:
For this sequence, we have that:
[tex]a_1 = -\frac{1}{5} = -0.2, n = 10, q = 4[/tex]

Linda goes for a run every day after school, but she likes to make some workouts easier than others. On Monday, Linda ran 3.5 miles in 35 minutes. On Tuesday, she ran 3 miles in 40 minutes. On which day did Linda run at a faster pace?
Answer:
Linda ran at a faster pace on Monday with a speed of 6 miles/hour
Step-by-step explanation:
Rate or Speed = Distance/Time
On Monday, Linda ran 3.5 miles in 35 minutes.
Converting 35 minutes to hours
60 minutes = 1 hour
35 minutes = x
x = 35/60
x = 0.5833333333 hour
Rate or speed = 3.5miles/0.5833333333 hour
= 6 miles/hour
On Tuesday, she ran 3 miles in 40 minutes.
Converting 40 minutes to hours
60 minutes = 1 hour
40 minutes = x
x = 40/60
x = 0.6666666667 hour
Rate or speed = 3miles/0.6666666667 hour
= 4.5 miles/hour
Linda ran at a faster pace on Monday with a speed of 6 miles/hour

In triangle, HIJ, HI = 48, and IJ = 27. What is the range of values for the length third side?
Answer:
The range is between 21 and 75
Step-by-step explanation:
"The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side."
Any two sides of of a triangle added together cannot be equivalent to or less than the length of the third side. Knowing this, we can figure out the range. If you add 48 and 27, you get 75. We know 75 is the top of the range, the length of the third side cannot be 75 or greater. Going the other way, if you assume that the third side is one of the smaller ones, you can identify 48 as the largest value. If you subtract 27 from 48 you get 21, so the length of the third side cannot be 21 or lower.
This gives us the range. Just keep this rule in mind. Hope this helped!

A food store makes a 12-lb mixture of granola, clusters, and raisins. The cost of granola is $1.00 per pound, clusters cost $3.00 per pound, and raisins cost $2.00 per pound. The mixture calls for twice as much granola as clusters. The total cost of the mixture is $21.00. How much of each ingredient did the store use?
Answer:
The food store used 3 lbs of clusters, 6 lbs of granola, and 3 lbs of raisins.
Step-by-step explanation:
Given that:
A food store makes a 12-lb mixture of granola, clusters, and raisins.
The cost of granola = 1.00 per pound
The cost of clusters = 3.00 per pound
The cost of raisins = 2.00 per pound
Let granola be = g; cluster be c and raisins be r
Then, g + c + r = 12
Similarly, the mixture calls for twice as much granola as clusters.
2c + c + r = 12
3c + r = 12
r = 12 - 3c
2c(1) + 3c + 2r = 21
2c + 3c + 2r = 21
5c + 2r = 21
5c + 2(12 -3c) = 21
5c + 24 - 6c = 21
24 - c = 21
-c = 21 - 24
c = 3
Thus, cluster c = 3 lbs
granola = 2(c) = 2(3) = 6 lbs
raisins = 12 - 3c
= 12 - 3(3)
= 12 - 9
raisins = 3 lbs

chicken sandwich for lunch. 12 students
ate a chicken sandwich, how many essere
cafeteria?
Answer: 48
Step-by-step explanation:
If 25% of the people in the cafeteria is equal to 12, then you have to work out the value of 100%.
100 divided by 4 is 25.
Therefore, if we times 25 by 4, then we get 100%.
12 times by 4 is 48, meaning there are 48 people in total in the cafeteria.
