The equation to find the cost (c) is C= 0.30b + 0.10.
The cost to make each bracelet is $10.70.
We have,
Shawn buy beads for $0.30 each.
The wire used to make each bracelet costs $0.10.
If C is the cost then the equation for the cost is
C = 0.30b + 0.10
where b is number of beads.
Now, Number of beads = 15 then cost is
C = 0.30(15) + 0.10 = $4.6
and, if number of beads is 20 then the cost is
C = 0.30(20)+ 0.10 = 6.1
Then, the total cost is = 4.6 + 6.1 = $10.7

Using the information below, answer the next 3 questions: The percent of fat calories that a person in America consumes each day is normally distributed with a mean of about 36 and a standard deviation of about 10. Suppose that 16 individuals are randomly chosen. For the group of 16, find the probability that the average percent of fat calories consumed is more than thirty-five (Round to 3 decimal places)
Answer: 0.655
Step-by-step explanation:
Let X be a random variable that represents percent of fat calories that a person in America consumes each day.
As per given , X is normally distributed with a mean [tex]\mu=36[/tex] and a standard deviation [tex]\sigma=10[/tex].
Sample size : n= 16
The probability that the average percent of fat calories consumed is more than 35:
[tex]P(\overline{X}>35)=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{35-36}{\dfrac{10}{\sqrt{16}}})\\\\=P(Z>\dfrac{-1}{\dfrac{10}{4}})\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=P(Z>\dfrac{-4}{10})\\\\=P(Z>-0.4)\\\\=P(Z<0.4)\ \ \ [P(Z>-z)=P(Z<z)]\\\\=0.655\ \ \ [\text{By p-value table}][/tex]
Hence, Required probability =0.655

P(n,r)= n!
(n−r)! = ?
n (objects) = 5
r (sample) = 3
Answer:
P(n,r)=P(5,3)
= 5! /(5−3)!
= 60
The result shows that Mark can put the 5 pebbles in the 3 fish tanks in 60 different ways, if each fish tank must have at least one pebble. Using the permutation calculator, the number of ways is calculated to be 60 ways.

Anna is ordering t-shirts for a community run. The company Anna is ordering from charges $12 per shirt and a shipping fee of $8. Based on this information, which function can be used to represent the relationship between the total cost, t, and the number of shirts Anna orders, m?
A. t=12m−8
B. t = 8m + 12
C. t = 12m + 8
D. t=8m−12
Answer:
D. t = 12m + 8
Step-by-step explanation:
This is the correct answer. I took the test.
The linear function that models the situation is:
[tex]t = 12m + 8[/tex]
A linear function is modeled by:
[tex]t(m) = am + b[/tex]
In which:
a is the slope, which is the rate of change per unit m.b is the y-intercept, which is the "fixed" value.In this problem:
Charge of $12 per shirt, hence [tex]a = 12[/tex].Shipping fee of $8, hence [tex]b = 8[/tex]Thus, the relationship is modeled by:
[tex]t = 12m + 8[/tex]

How can you tell if an equation will have a certain answer?
Answer:
Check whether the given value is a solution to the equation
Step-by-step explanation:
If the numbers you get from evaluating the two expressions are the same, then the given value is a solution of the equation (makes the equation true). If the numbers don't match, the given value is not a solution of the equation (makes the equation false).
