y = 5x + 50
Roberta:
y = 5x + 2

Answers
Answer:
10
Step-by-step explanation:
First, you multiply j and k together. j·k=6·4= 24.
Next, you multiply 24 by 2.5. That is equal to 60.
After that, since j=6, you divide 60 by 6.
That is equal to 10.

In the diagram, AB is the tangent to the circle at P and PX is the diameter.
Given that BPQ = 42°, find PQX, PXQ and XPQ.
Answers
Answer:
see explanation
Step-by-step explanation:
∠ PQX = 90° ( angle in a semicircle )
∠ PXQ = 42° ( alternate angle theorem )
Angle between tangent and diameter is right, thus
∠ XPQ = 90° - 42° = 48°

10. A certain strain of bacteria occurs in all raw milk. Tests of uncontaminated raw milk conducted by the Health Department found that the bacteria count per milliliter is normally distributed with a mean of 3500 and standard deviation of 300. a) What is the probability of finding a bacteria count of between 3200 and 3400 in a milliliter of raw milk? b) What percentage of the uncontaminated raw milk has a bacteria count per milliliter between 3200 and 3400? c) For this normal distribution, what is the percentage of the area under the normal curve for a bacteria count per milliliter less than zero? As bacteria count cannot be less than 0, is this small enough to disregard when claiming that the bacteria count per milliliter is normally distributed? Explain your answer.
Answers
Answer:
a) 0.21078
b) 21.078%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean of 3500 and standard deviation of 300.
a) What is the probability of finding a bacteria count of between 3200 and 3400 in a milliliter of raw milk?
For x = 3200
z = 3200 - 3500/300
z = -1
Probability value from Z-Table:
P(x = 3200) = 0.15866
For x = 3400
z = 3400 - 3500/300
z = -0.33333
Probability value from Z-Table:
P(x = 3400) = 0.36944
The probability of finding a bacteria count of between 3200 and 3400 in a milliliter of raw milk
P(x = 3400) - P(x = 3200)
= 0.36944 - 0.15866
= 0.21078
b) What percentage of the uncontaminated raw milk has a bacteria count per milliliter between 3200 and 3400?
We convert the answer in part a) to percentage
= 0.21078 × 100
= 21.078%

Amir has a bag of dimes and quarters. He has a total of 31 coins worth $5.20.
Let x represent the number of dimes and y represent the number of quarters.
Which system of equations would be used to find out how many dimes and quarters Amir has?
Answers
Answer:
B is the correct answer.
Step-by-step explanation:
This is the given information for which system of equations would be used to find out how many dimes and quarters Amir has?
x = dimes x = 0.10 or 0.1
y = quarters y = 0.25
31 coins
worth $5.20 = 5.2
x + y = 31

Answer:
∠b = 88 - 5x
Step-by-step explanation:
If a and b are complementary, then sum of two angles is 90

∠b = 90 - 5x - 2
∠b = 88 - 5x

What are the values of the domain in the following graph?
A.the domain is represented by cm/ year
b. The domain is represented by the height of the horse
c. The domain is represented by the age
d. The domain is represented by the average growth of the horse
Answers
Answer:
We conclude that The domain is represented by age.
Thus, the option 'c' is true.
Step-by-step explanation:
We know that the domain of a function is the entire set of input values of the independent variable 'x' for which the function remains real and defined.
Given the attached graph, we can observe that height is dependent on age (years). In other words, the age (years) is basically an independent variable.
Therefore, we conclude that The domain is represented by age.
Thus, the option 'c' is true.
Answer:
C. The domain is represented by the age

A cereal box manufacturer changes the size of the box to increase the amount of cereal it contains. The expressions 16+6.2n and 10+6.5n, where n is the number of smaller boxes, are both representative of the amount of cereal that the new larger box contains. How many smaller boxes equal the same amount of cereal in the larger box?
Answers
Answer:
20 smaller boxes
Step-by-step explanation:
Given
Smaller Box = 10 + 6.5n
Larger Box = 16 + 6.2n
Required
Determine the number of small box in each box
To do this, we simply equate both expressions:
[tex]Smaller\ Box = Larger\ Box[/tex]
[tex]10 + 6.5n = 16 + 6.2n[/tex]
Collect Like Terms
[tex]6.5n - 6.2n = 16 - 10[/tex]
[tex]6.5n - 6.2n = 6[/tex]
[tex]0.3n = 6[/tex]
Make n the subject
[tex]n = 6/0.3[/tex]
[tex]n = 20[/tex]
Hence, there are 20 smaller boxes
