Answer:
[tex]\frac{2.54cm}{1in}[/tex]
Step-by-step explanation:
Given
[tex]3.6m = 3.6m * \frac{100cm}{1m} * \frac{2.54cm}{1in} * \frac{1ft}{12in} * \frac{1yd}{3ft}[/tex]
Required
Which ratio is incorrect
Each ratio is a conversion of 1 unit to the other.
Taking them one at a time.
The first is [tex]\frac{100cm}{1m}[/tex]
[tex]1m = 100cm[/tex] --- The ratio is correct
The next is: [tex]\frac{2.54cm}{1in}[/tex]
[tex]2.54\ cm = 1\ in[/tex]
The conversion is correct; however the ratio is incorrect.
This is so because, the first ratio ([tex]\frac{100cm}{1m}[/tex]) has centimetre as the numerator
The next should have centimetre has its denominator in order to cancel out the units.
So, the correct ratio is:
[tex]\frac{1\ in}{2.54\ cm}[/tex]

sonja and jake just got married. they received $4500 in gift money and deposited it into a savings account that pays %2.85 simple interest. how much will they have in savings after 3 years?
9514 1404 393
Answer:
$4884.75
Step-by-step explanation:
The amount in a simple interest account is given by the formula ...
A = P(1 +rt)
Here, we have principal P=$4500, interest rate r=0.0285, and time t=3. Then the amount in the savings account will be ...
A = $4500(1 +.0285·3) = $4500·1.0855 = $4884.75

Express the given function h as a composition of two functions f and g so that h(x)=(fog)(x) where one of the functions is 8x-9.
h(x)=(8x-9)^2
f(x) = ?
g(x) = ?
Given:
h is composition of two functions f and g.
[tex]h(x)=(f\circ g)(x)[/tex]
One of the function is 8x-9.
[tex]h(x)=(8x-9)^2[/tex]
To find:
The functions f(x) and g(x).
Solution:
We know that,
[tex]h(x)=(f\circ g)(x)=f[g(x)][/tex]
We have,
[tex]h(x)=(8x-9)^2[/tex]
Here, first function is 8x-9 and the second is square of it.
In [tex](f\circ g)(x)=f[g(x)][/tex], first function which is applied is g(x) and the second function is f(x).
Let [tex]g(x)=8x-9[/tex] and [tex]f(x)=x^2[/tex].
[tex]h(x)=f[8x-9][/tex]
[tex]h(x)=(8x-9)^2[/tex]
So, our assumption is correct.
Therefore, the required functions are [tex]g(x)=8x-9[/tex] and [tex]f(x)=x^2[/tex].

jodi pelfrey obtained a single payment of 1600 to buy a pedigreed dog she agrees to repay the loan at an ordinary interest rate of 7.5%. What is the maturity value of her loan
Answer:
$120 ordinary payment. (%7.5 of $1,600)
Maturity Value: $1,600?
Step-by-step explanation:
Using the maturity value formula, $1,600 is the maturity value. Because this question doesn't state a time period of investment, it's difficult to determine the answer.
Formula: V = P * (1+R)^T
V – Maturity ValueP – Principal InvestedR – Rate of InterestT – Time of InvestmentHopefully this helps.
The maturity value of her loan is 1720
Interest value of an amount of moneyGiven the following parameters;
Payment amount = 1600Percent Interest = 7.5%Interest = 0.075 * 1600
Interest = 120
Maturity value = 1600 + 120
Maturity value = 1720
Hence the maturity value of her loan is 1720

A jar contains 125 marbles. Given 2% of the marbles are green, 62% of the marbles are blue, and the rest are red, how many marbles are in the jar?
There are red marbles in the jar.
Answer:
Red Marbles = 110
Step-by-step explanation:
Green Marbles =125 × 6 /100 = 7.5
Blue Marbles = 125 × 6 100 = 7.5
Red Marbles = Total Number of Marbles -[Number of Green Marbles + Number of Blue Marbles]
Red Marbles = 125 −( 7.5 + 7.5 ) = 125 − 15 = 110
Red Marbles = 110

Sarah goes to her local pizza parlor and orders a pizza. She can choose either a large or a medium pizza, can choose one of seven different toppings, and can have three different choices of crust. How many different pizzas could Sarah order?
Answer:
[tex]Pizza = 42[/tex]
Step-by-step explanation:
Given
[tex]Size = 2[/tex] (Large or Medium)
[tex]Toppings = 7[/tex]
[tex]Crusts = 3[/tex]
Required
Determine the number of different pizza she can order
Since there is no restriction to what she can order.
She can pick one of the 2 sizes; one of the 7 toppings and one of the 3 crusts.
Number of Pizza is then calculated as:
[tex]Pizza = Size * Toppings * Crusts[/tex]
[tex]Pizza = 2 * 7 * 3[/tex]
[tex]Pizza = 42[/tex]
Hence, she can order 42 different pizzas

% voted Republican in 1976.
This is a (select)
Answer: 52.9% vote Republican in 1976
This is a marginal relative frequency.
Let's complete the table for 1976 elections as well as subsequently then for 2021 elections. It can also be done vice-versa.
1976 elections:
Democrat voting will be:
= [tex](\frac{12}{27}\times 100+ \frac{12}{24}\times 100)[/tex]
= [tex]44.45+50[/tex]
= [tex]94.45[/tex] (%)
Republic voting will be:
= [tex](\frac{15}{27}\times 100 + \frac{12}{24}\times 100 )[/tex]
= [tex]55.55+50[/tex]
= [tex]105.55[/tex] (%)
Total will be:
= [tex]\frac{27+24}{51}\times 100[/tex]
= [tex]100[/tex] (%)
2012 elections:
Democrat voting will be:
= [tex](\frac{12}{24}\times 100 +\frac{12}{24}\times 100 )[/tex]
= [tex]50+50[/tex]
= [tex]100[/tex] (%)
Republic voting will be:
= [tex](\frac{15}{27}\times 100+\frac{12}{27}\times 100 )[/tex]
= [tex]55.55+44.45[/tex]
= [tex]100[/tex] (%)
Total will be:
= [tex]\frac{27+24}{51}\times 100[/tex]
= [tex]100[/tex] (%)

g Bonus: Assume that among the general pediatric population, 7 children out of every 1000 have DIPG (Diffuse Intrinsic Pontine Glioma, an aggressive brain cancer). A pharmaceutical company designs a screening test for DIPG that has a 98% sensitivity and an 84% specificity. Given that someone has a positive test result, what is the probability they don't have DIPG
Answer:
0.9586
Step-by-step explanation:
From the information given:
7 children out of every 1000 children suffer from DIPG
A screening test designed contains 98% sensitivity & 84% specificity.
Now, from above:
The probability that the children have DIPG is:
[tex]\mathbf{P(positive) = P(positive \ | \ DIPG) \times P(DIPG) + P(positive \ | \ not \DIPG)\times P(not \ DIPG)}[/tex][tex]= 0.98\imes( \dfrac{7}{1000}) + (1-0.84) \times (1 - \dfrac{7}{1000})[/tex]
= (0.98 × 0.007) + 0.16( 1 - 0.007)
= 0.16574
So, the probability of not having DIPG now is:
[tex]P(not \ DIPG \ | \ positive) = \dfrac{ P(positive \ | \ not DIPG)\timesP(not \ DIPG)} { P(positive)}[/tex]
[tex]=\dfrac{ (1-0.84)\times (1 - \dfrac{7}{1000}) }{ 0.16574}[/tex]
[tex]=\dfrac{ 0.16 ( 1 - 0.007) }{0.16574}[/tex]
= 0.9586
