Meredith borrows 12560 and pays 2 percent simple interest each year for 4 years what is the total amount of interest that she will pay on the loan
Answer:
$13564.8
Step-by-step explanation:
Step one:
given data
principal= $12560
rate= 2%= 0.02
time= 4years
Required:
the simple interest
Step two:
the expression for the simple interest is
A= P(1+rt)
substitute
A=12560(1+0.02*4)
A=12560(1+0.08)
A=12560(1.08)
A=13564.8
$13564.8
it's C (11,555.20)

Answer:
The pay is $93.50 (if counting the 15 minutes) or $88
Step-by-step explanation:
Just calculate how many hours the person worked, and multiply that by 11. They worked 8 hours, so they get $88. If you're counting the 15 minutes the person worked too, divide 11 by 4 (there are four 15 minute segments in an hour) which is 2.75. They worked 15 minutes over an hour twice so you just add $5.50 to $88, which is $93.50.

Jessica, Hans, and Tom sent a total of 95 text messages during the weekend. Tom sent 3 times as many messages as Hans. Jessica sent 10 more messages than Hans. How many messages did they each send?
Answer: Manal = 27 messages
Elisa = 17 messages
Abdulrahman = 51 messages
Step-by-step explanation:
Let tye number of messages that Manal sent be x.
Since Eissa sent 10 fewer messages than Manal, this will be:
= x - 10
Abdulrahman sent 3 times as many messages as Eissa. This will be:
= 3(x - 10) = 3x - 30
We are also told that Manal, Abdulrahman, and Eissa sent a total of 95 text messages. This will be:
x + (x - 10) + (3x - 30) = 95
x + x - 10 + 3x - 30 = 95
x + x + 3x - 10 - 30 = 95
5x - 40 = 95
5x = 95 + 40
5x = 135
x = 135/5
x = 27
Manal = x = 27
Elisa = x - 10 = 27 - 10 = 17
Abdulrahman = 3x - 30 = 3×27 - 30 = 81 - 30 = 51
Manal = 27 messages
Elisa = 17 messages
Abdulrahman = 51 messages

A sample of 29 boxes of cereal has a sample standard deviation of 0.81 ounces. Construct a 95% confidence interval to estimate the true standard deviation of the filling process for the boxes of cereal.
a. ( 0.427,1.144)
b. (0.515,1.105)
c. (0.726,0.726)
Answer:
The 95% confidence interval is [tex]0.6428 < \sigma < 1.0954[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 29
The sample standard deviation is [tex]s = 0.81[/tex]
Generally the 95% confidence interval to estimate the true standard deviation is mathematically represented as
[tex]\sqrt{\frac{(n- 1)s^2 }{ X^2_( \frac{\alpha }{2 } , n-1)} } < \sigma < \sqrt{\frac{(n- 1)s^2 }{ X^2_(1- \frac{\alpha }{2 } , n-1)} }[/tex]
Generally from the chi -distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of [tex]df = 29 - 1 = 28[/tex] is
[tex]X^2 _{\frac{\alpha }{2} , 28 } =44.46079184[/tex]
Generally from the chi -distribution table the critical value of [tex]1 - \frac{\alpha }{2}[/tex] at a degree of freedom of [tex]df = 29 - 1 = 28[/tex] is
[tex]X^2 _{(1 - \frac{\alpha }{2}) , 28 } = 15.30786055[/tex]
So
[tex]\sqrt{\frac{(29- 1)0.81^2 }{ 44.46079184 } } < \sigma < \sqrt{\frac{(29- 1)0.81^2 }{15.315.307860551 }[/tex]
=> [tex]0.6428 < \sigma < 1.0954[/tex]

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
An insurance company offers a term life insurance policy with a renewable premium.
The first year premium is $900
The premiums increase 5.5% each year,
[tex]A=Pe^r^t[/tex]
5.5%=5.5/100 =0.055
[tex]A = 900(e)^0^.^0^5^5^\times^7[/tex]
[tex]A=900e^0^.^3^8^5[/tex]
A=900×1.46
A=$1308
Hence, if first year premium is $900 and the premiums increase 5.5% each year then the premium be in 7 years is $1308

A friend recently planned a camping trip. He had two flashlights, one that required a single 6-V battery and another that used two size-D batteries. He had previously packed two 6-V and four size-D batteries in his camper. Suppose the probability that any particular battery works is p and that batteries work or fail independently of one another. Our friend wants to take just one flashlight. For what values of p should he take the 6-V flashlight
Answer:
The values of p = 0 < p ≤ 2/3
Step-by-step explanation:
First we write the probability of 6V flashlight working representing it as a binomial mass function of a binomial random variable
P ( 6v flashlight working ) = P ( at least one 6V battery works )
= P ( 1 6v battery work ) + P ( 2 6v battery work )
= b( 2; 2, p ) + b( 1; 2, p )
write out a formula of b( 2; 2, p ) + b( 1; 2, p )
P ( 6v flashlight working ) = p^2 + 2p( 1 - p )
Next we write the probability of D flashlight working representing it as a binomial mass function of a binomial random variable
P ( D flashlight works ) = p ( at least two D batteries works )
= b( 4; 4, p ) + b(3;4, p ) + b(2; 4, p )
write out a formula of b( 4; 4, p ) + b(3;4, p ) + b(2; 4, p )
P ( D flashlight works ) = [tex]P^4 + 4p^3 ( 1- p ) + 6p^2 ( 1- p)^2[/tex]

Which function has vertical asymptotes at x=-1 and x=-2, an x-intercept at(8,0) , and no holes?
Answer:
y = (x - 8)/((x + 1)(x + 2))
Step-by-step explanation:
vertical asymptotes are given as at x=-1 and x=-2
Now, vertical assymptotes are values of x when the denominator is zero.
Thus, the function of the denominator can be written as;
(x + 1)(x + 2)
We are also told that x-intercept at (8,0).
Which means that y is zero when x is 8.
Thus, numerator is 8 when y is zero.
Thus, numerator can be expressed as (x - 8)
Thus,the function is now;
y = (x - 8)/((x + 1)(x + 2))
