Eric had $197 in his savings account before he was paid his weekly salary. His current savings balance is $429. How much money does Eric earn each week? (Form an equation.)
Answers
Answer:
[tex]197+\text{ n= 429}[/tex]Explanation:
Here, we want to get the amount of money Eric earns per week
Let the amount earned be n
Now, to get the value earned, we have to subtract the value he had before from what he has now or simply add what he had before to what he earned now and equate to his total balance now
Mathematically, we have that as:

Answers
Step 1: Let's review the information given to us to answer the exercise correctly
Amount of pure drug in the solution = 8 grams
Amount of solution = 75 mL
Step 2: Let's answer the question, as follows:
Percent strength of the solution = Amount of pure drug in the solution/Amount of solution * 100
Replacing with the values we know:
Percent strength of the solution = 8/75 * 100
Percent strength of the solution = 0.10666 * 100

The president of the student council wants to survey the student population about parking. She decides to take a random sample of 100 of the 1,020 students at the school. She gets an alphabetical list of the students, and numbers them from 0001 to 1020. Then, using a random number table, and starting at a random line, she selects 100 unique numbers between 0001 and 1020. Is this a simple random sample?
No, because the sample could contain repeating numbers.
No, because the sample could contain numbers other than numbers between 0001 and 1020.
Yes, because each student and sample of 100 has the same chance of being selected.
Yes, because each student is represented by a 4-digit number from 0001 to 1020.
Answers
Is this a simple random sample: Yes, because each student and sample of 100 has the same chance of being selected.
What is a simple random sample?A simple random sample can be defined as a subset of items that are selected from a larger data set or statistical population, with each member of the subset having an equal or the same probability (chance) of being selected.
This ultimately implies that, each member of the subset are selected by chance and randomly, and as such a simple random sample is an unbiased representation of a larger data set or a statistical population.
In this context, we can reasonably infer and logically deduce that the data set or statistical population described in this scenario is a simple random sample.

One half of a number increased by a second number equals 5. One half of the first number decreased by the second number equals 1. Find the two numbers.

What should be done to both sides of the equation in order to solve 1/3 x=4? Divide by 4Multiply by 4 Divide by 1/3Multiply by 1/3
Answers
The given equation is,
[tex]\frac{1}{3}x=4[/tex]So, from this equation , we have to find the value of x. The left hand side of the equation has x with 1/3 as coefficient, therefore, inorder to make it x, we have to,
[tex]\frac{1}{3}x\times3\rightarrow x[/tex]as the thress get cancelled. If we do some operation on one side of the equal sign, it is to be applied on the other side also so as to maintain the equivalency.
So here we have to multiply by 3.
But in option, there is no as such given , but it is given that divide by 1/3.
[tex]\frac{\frac{1}{3}x}{\frac{1}{3}}\rightarrow\frac{1}{3}x\times3^{}^{}[/tex]which is equuivalent to multiplying by three.

Given that,
The probability of matching x successes on n further trials in an experiment with two possible outcomes is known as the binomial probability (commonly called a binomial experiment).

p=43%=0.43
We must locate Four persons were questioned, and none expressed concern about phone call monitoring by companies.

For the following, I have to find where the orthocenter, the centroid, and the circumcenter are within the diagram
Answers
Orthocenter
Let
A(2,0)
B(3,2)
C(6,0)
step 1
Find out the slope AB
m=(2-0)/(3-2)
m=2/1
m=2
Remember that
If two lines are perpendicular, then, their slopes are negative reciprocal
so
the slope of the altitude that passes through C is -1/2
Find out the equation of the altitude that passes through C
y=mx+b
we have
m=-1/2
point C(6,0)
substitute
0=-(1/2)(6)+b
solve for b
0=-3+b
b=3
equation is y=-(1/2)x+3 -------> equation 1
step 2
Find out the slope BC
m=(0-2)/(6-3)
m=-2/3
so
the slope of the altitude that passes through A is 3/2
Find out the equation of the altitude that passes through A
y=mx+b
we have
m=3/2
point A(2,0)
0=(3/2)(2)+b
solve for b
0=3+b
b=-3
y=(3/2)x-3 ------> equation 2
step 3
the intersection point equation 1 and equation 2 is the orthocenter
y=-(1/2)x+3 -----> equation 1
y=(3/2)x-3 ------> equation 2
solve the system
solve by graphing
using a graphing tool
the intersection point is (3,1.5)
that means
the orthocenter is (3,1.5)

"Melissa sleeps for 9 hours and wakes up at 5:30 am," in this case Melissa would drink coffee since she had woke up at 5:30 am. "Melissa sleeps for 7 hours and wakes up at 6 am," in this case Melissa would drink coffee since she had less than 8 hours of sleep. In conclusion, The only time Melissa wouldn't had drank coffee is when she had slept for 8 hours and woke up at 7 am. That is because had slept more than 8 hours and had woke up after 7 am.
Find x and the measure of angle 1
Answers
The measure of angle 1 is 42° . Angles Central angles can be expressed as Central angle = (Arc length 360o)/(2r) degrees or Central angle = Arc length/r radians, where r is the radius of the circle.
What is meant by angle?When two straight lines or rays intersect at a common endpoint, an angle is formed. An angle's vertex exists as the familiar point of contact. Angle is derived from the Latin word angelus, which means "corner." An angle is formed when two line segments are joined at a single point, or when two line segments meet at a common endpoint. This common point is known as the angle's vertex, and the two line segments are known as the angle's sides or arms. Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle, and full rotation are the names of basic angles. An angle is a geometrical shape formed by connecting the ends of two rays.∴ The measure of angle 1 is 42°

A woman borrows #20 000 for 4 weeks. She agrees to pay #25 000 back at the end of the 4 weeks. How much interest does she pay over the a 4 weeks? b How much interest does she pay per week?how to solve
Answers
The interest she pays over 4 weeks is #5000 and the interest she pays per week is #1250.
According to the question,
We have the following information:
A woman borrows #20 000 for 4 weeks.
She agrees to pay #25 000 back at the end of the 4 weeks.
Now, we will subtract the borrowed amount from the amount paid after 4 weeks to find the interest paid after 4 weeks.
(a) Interest paid over 4 weeks = #(25000-20000)
Interest paid over 4 weeks = #5000
(b) Now, we can easily find the interest paid per week by the interest paid over 4 weeks by the total number of weeks.
Interest paid per week = Interest paid in 4 weeks/4
Interest paid per week = 5000/4
Interest paid per week = #1250
Hence, the answers to part a is #5000 and the answer to part b is #1250.
