Maria and Lamar are playing a game. Maria noticed that the digits of her
score could be reversed to form Lamar's score. Maria's score is 18 more
than Lamar's score. Maria's score is a multiple of 5. What is Maria's score?
Answer:
20
Step-by-step explanation:
because 20 reversed is 02 and plus 18 is 20 and 20 is a multiple of 5
Answer:
The answer is 20!
Step-by-step explanation:
Had to do this on a sheet of paper.

If 3 balls are drawn at random from a bag containing 3 red and 4 blue balls,
what is the expected number of red balls in the sample?
Answer:
The expected number of red balls in the sample is 1.2857.
Step-by-step explanation:
The balls are chosen without replacement from the sample, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The expected value of the hypergeometric distribution is:
[tex]E(X) = \frac{nk}{N}[/tex]
3 red balls in the sample:
This means that [tex]k = 3[/tex]
3 balls are drawn:
This means that [tex]n = 3[/tex]
Total of 3 + 4 = 7 balls:
This means that [tex]N = 7[/tex]
What is the expected number of red balls in the sample?
[tex]E(X) = \frac{nk}{N} = \frac{3*3}{7} = 1.2857[/tex]
The expected number of red balls in the sample is 1.2857.

A line is parellel to y=3x+2 and intersects the point (2,9). What is the equation of this parellel line
Answer: y= -3x
Step-by-step explanation:
Use the slope-intercept form to find the slope.
m = −3
To find an equation that is parallel to y = −3x + 2, the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula.
(0,0)
m = −3
Using the point-slope form
y − y1 = m (x − x1), plug in
m = −3, x1 = 0, and y1 = 0.
y − (0) = (−3) (x−(0))
Solve for y
y = −3x
Answer:
y=3x+3
Step-by-step explanation:
(2,9)
x=2
y=9
-Slot these numbers into the equation y=mx+c
-Solve for c
y=3x+c
9=3(2)+c (We have substituted y for 9 and x for 2)
-Solve
9=6+c
(rearrange)
c+6=9
c=9-6
c=3
We have found our y-intercept (c)
Add this value into the original equation (replace the other y-intercept with your new value)
y=3x+3

Michael surveyed a random sample of students in his school about the number of sports they play. There are 300 students in Michael's school. Use the
results of the survey to estimate the number of students in Michael's school who play exactly one sport.
Answer:
75 students
Step-by-step explanation:
From the table, we can calculate the total number of students surveyed by Michael:
Total student surveyed = 13 + 15 + 32 = 60 students
We can see that out of the 60 students, 15 students played exactly one sport. Hence:
Proportion of students playing exactly one sport = 15 / 60 = 0.25
Based on the result of the survey, if they are 300 students, number of students playing exactly one sport is:
Number of students playing exactly one sport = proportion * total students = 0.25 * 300 students = 75 students

Answer:
261.8 in^3
Step-by-step explanation:
The volume of a right circular cone is [tex]V=\frac{1}{3} \pi r^2h[/tex].
r is the radius of the circular base (r = 5 in this problem), and h is the height (h = 10 in this problem.
[tex]V=\frac{1}{3} \pi (5^2)(10)=\frac{1}{3}(250\pi) \approx 261.8\text{ in}^3[/tex]
A truck rental company rents a moving truck One Day by charging $39 + 0.09 per mile write a linear equation that relates the cost c in dollars of renting the truck to the number x of miles driven and what is the cost of renting the truck if the truck is driven 160 MI
Answer:
[tex](a)\ c(x) = 39 + 0.09 x[/tex]
[tex](b)\ \$53.4[/tex]
Step-by-step explanation:
Given
[tex]Base\ Charge = \$39[/tex]
[tex]Rate = 0.09[/tex] per mile
Solving (a): Linear Equation
The total charges (c(x)) is: the base charge + the rate * number of miles (x).
So, we have:
[tex]c(x)= 39 + 0.09 * x[/tex]
[tex]c(x) = 39 + 0.09 x[/tex]
Solving (b): Cost of rent, if miles = 160
This implies that x = 160
So, we have:
[tex]c(x) = 39 + 0.09 x[/tex]
[tex]c(160) = 39 + 0.09 *160[/tex]
[tex]c(160) = 39 + 14.4[/tex]
[tex]c(160) = 53.4[/tex]

1.Find the surface area
2.Find the volume
Answer:
1.106 inches squared 2. 60 inches cubed
Step-by-step explanation:
The surface area is just calculated like this 7.5*2*2 (because there are 2 faces) = 30 then 2*4*2= 16 then 4*7.5*2= 60 then you add them to get 106
For the second all you do is multiply the three values which gets you 60
would be amazing if you picked this as brainliest :)
Answer:
Step-by-step explanation:
.Find the surface area
(7,5*4) *2 + (7,5*2) *2 + (4*2) * 2 =
60+ 30+ 16 => 106 inch²
2.Find the volume
7,5 * 2*4 =>60 inch³

Find the the measure of angle 5.
Answer:
Angle 5 would be 119 degrees.
Step-by-step explanation:
This is because the angle that is 61 degrees and angle 5 are both supplementary angles. Supplementary angles would add up to 180 degrees and would lie on the same side of the line. So 180 minus 61 is 119.
Rajesh gave 1/2 of his provident fund to his wife,1/4 to his son and the remainder was to be divided equally between his two brothers so that each brother got Rs 10000.
What was the amount of provident fund?
Answer:
$ 80 000
Step-by-step explanation:
provident fund -- x
Wife -- 1/2 of x
Son -- 1/4 of x
Two brothers -- x - (x/2 - x/4)
Therefore, x - (x/2 - x/4) / 2 = 10 000
x = 80 000
Therefore, the amount of provident fund is $ 80 000
