Let us say that:
x = the number of T shirts bought = 4
y = the number of leather jackets bought = 1
a = the price of the T shirts
b = the price of the leather jackets
With the given variables, we can say that the total cost
is:
total cost = a x + b y
Since, b = 6 a, therefore:
total cost = a x + 6 a y
total cost = a (x + 6 y)
Since total cost is 209, therefore we can calculate for a
since x and y are also given:
209 = a (4 + 6 * 1)
209 = a (10)
a = $20.9
<span>Therefore each T shirt cost $20.9</span>
Answer:
A) $204 B) $331.50
Step-by-step explanation:
For both scenarios, you just multiply the amount of hours worked by the amount per hour to find the total amount made.
Answer:
Step-by-step explanation:
The Maclaurin series of a function f(x) is the Taylor series of the function of the series around zero which is given by
We first compute the n-th derivative of 
, note that
Now, if we compute the n-th derivative at 0 we get
and so the Maclaurin series for f(x)=ln(1+2x) is given by
Answer:
The point estimate for the proportion of women with BRCA1 mutation is 0.168
Step-by-step explanation:
The point estimate for the proportion of women with BRCA1 mutation is the number of women with this mutation divided by the size of the sample.
Of the 173, they found that 29 had BRCA1 mutations.
29/173 = 0.168
The point estimate for the proportion of women with BRCA1 mutation is 0.168
