Refer to the given line from a random number table. Which numbers represent the first 2 students selected?
24000 75983 62200 91518 10198 88936
A.) 2400, 0759
B.) 2400, 8362
C.) 0759, 1518
D.) 0759, 1019
Answer:
C 0759, 1518
Step-by-step explanation:
The numbers which represent the first 2 students selected is the option D.) 0759, 1019.
What is Random Number Table?Random number table are a table of numbers arranged in an unpredictable sequence. These tables are used to select a random sample in certain situations.
We have the line in the random table as,
24000 75983 62200 91518 10198 88936
There are 1020 students in total.
So we have to select four digit numbers of the sequence 0001, 0002, ..........., 1019, 1020.
Any number which is not included in this interval will not be selected.
From the reference line given, the four digit numbers are,
2400, 0759, 8362, 2009, 1518, 1019, 8889, ...
From this line, mark the numbers included in our interval from 0001 to 1020.
The numbers are 0759 and 1019. Other numbers are not included in our required interval.
Hence the first 2 students will represent as the numbers 0759 and 1019.

In American roulette, the wheel has the 38 numbers00, 0, 1, 2, ..., 34, 35, and 36 marked on equally spaced slots. If a player bets $1.00 on a number and wins, then the player keeps the dollar and receives an additional $35.00. Otherwise, the dollar is lost. Find the expected net gain to the player for one play of
Answer:
The expected net gain to the player for one play is -$0.0526.
Step-by-step explanation:
To find the expected net gain, we multiply each outcome by its probability:
Player wins:
Earns $35.
1 out of 38 numbers, so probability 1/38.
Player loses:
Loses $1.
37 out of 38 numbers, so probability 37/38.
Expected value:
[tex]\frac{1}{38} \times 35 - \frac{37}{38} \times 1 = -\frac{2}{38} = -0.0526[/tex]
The expected net gain to the player for one play is -$0.0526.
A circle has its center at (-4,8), and just touches the y-axis
Answer:i'm a bit confused
Step-by-step explanation:
are you asking a question or not?
Answer:
r = 4 units
Step-by-step explanation:
From the question it is not clear that what you want to ask. But as per me you are interested in finding the radius of the circle.
Since, circle is touching y-axis at has a center (-4, 8) so it's radius will be equal to the x-coordinate.
Here, x - coordinate is - 4
Since radius is a non negative number.
So, r = 4 units

The price of a home is $300,000. After a 10% down payment, the mortgage is $270,000. If this is financed with a 30-year fixed-rate mortgage at 6%, what is the total interest paid over 30 year
Answer:
The correct solution is "$1618.79".
Step-by-step explanation:
The given values are:
Home price,
= $300,000
Down payment,
= 10%
Mortgage,
= $270,000
Rate,
r = 6%
Time,
t = 30 years
As we know,
⇒ [tex]PV=P[\frac{1-(1+r)^{-n}}{r} ][/tex]
On substituting the values, we get
⇒ [tex]270 000= P[\frac{1-(1+\frac{6}{1200} )^{-12\times 30}}{\frac{6}{1200} } ][/tex]
⇒ [tex]P=1618.79[/tex] ($)
Answer:
312,764.40
Step-by-step explanation:
We previously determined that you will make monthly payments of $1,618.79 for 30 years to pay off the loan. You are paying $1,618.79 per month for 360 months.
1,618.79×360−270,000=312,764.40
You are paying a total of $312,764.40 in interest over the life of the loan.
What is the equation of the line in slope-intercept form?

draw the graph of y = 6 - 2x on the grid
Answer:
See attached image for the requested graph
Step-by-step explanation:
The values completed in the table and text boxes as shown, are all correct.
For the plotting of the points and drawing of the line, please see the attached image.
a. By putting the value of x one by one table can be completed
The complete table is attached below.
b. The graph is attached below.
c. solution of the given equation is x = 1.5.
Use the concept of fucntion which is defined as:
A relation between a collection of inputs and outputs is known as a function.
A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
The given fucntion is:
y = 6 - 2x
Since we know that this equation has degree one,
Therefore, it represents the equation of a line
Now to complete the table put the value of x in the fucntion one by one:
Put x = 0:
y = 6 - 2(0)
y = 6
Put x = 1:
y = 6 - 2(1)
y = 4
Put x = 2:
y = 6 - 2(2)
y = 2
Put x = 3:
y = 6 - 2(3)
y = 0
Put x = 4:
y = 6 - 2(4)
y = -2
Put x = 5:
y = 6 - 2(5)
y = -4
b. Now with the help of this table draw the graph of this fucntion.
The graph of it is attached below.
c. To solve the equation:
6-2x = 3
Subtract 6 on both sides,
-2x = -3
Divide both sides by -2 we get.
x = 1.5
Hence,
The solution of the given equation is 1.5.

solve the equation for z
5z-8=32
A. z=4
B. z=4.8
C. z=6
D. z=8
Answer:
Z=8 is the answer
Step-by-step explanation:
first, you add 8 to both sides which leaves you with 5z=40. then after that you divide both sides by 5 which leaves you with 5/5z = 40/5. then buy dividing 5 by 5 its leaves you with 1 which is equal to z because blank variables equal 1. On the other side if the equation 40 by 5 is 8 so that leaves you with z=8
Step-by-step explanation:
[tex] \tt{5z - 8 = 32}[/tex]
We want to remove the 8 first.
Step 1 : Since the original equation is minus 8 , we are going to use the opposite operation and add 8 to both sides.
⟶ [tex] \tt{5z - 8 + 8 = 32 + 8}[/tex]
Simplify -8 + 8 = 0 on the left. 32 + 8 = 40 on the right. Then we need to think about how to remove the coefficient 5.
⟶ [tex] \tt{5z = 40}[/tex]
Step 2 : Since the opposite of multiplication is division , we are going to divide both sides by 5.
⟶ [tex] \tt{ \frac{5z}{5} = \frac{40}{5}} [/tex]
Simplify. 5 / 5 = 1 on the left. 40/5 = 8 on the right. So , our answer is z = 8.
⟶ [tex] \tt{z = 8}[/tex]
[tex] \pink{ \boxed{ \boxed{ \text{Our \: final \: answer : \boxed{ \underline{ \tt{z = 8}}}}}}}[/tex]

In a certain breed of cattle, the length of gestation has a mean of 284 days and a standard deviation of 5.5 days. Thirty-four percent of gestation periods are longer than how many days, rounded to the nearest whole number?
Answer:
286
Step-by-step explanation:
Given :
Mean (m) = 284
Standard deviation (s) = 5.5
P(Z > x) = 0.34
According to the standardized formula :
Zscore = (x - m) / s
Uaing the Z probability calculator ; The Z value at P(Z > x) = 0.34 is 0.412
Hence, Zscore = 0.412
Zscore = (x - m) / s
0.412 = (x - 284) / 5.5
5.5 * 0.412 = x - 284
2.266 = x - 284
x = 2.266 + 284
x = 286.266
x = 286 (nearest whole number)
