Write two mixed numbers that have a sum of 3 4/5.
Answer:
Step-by-step explanation:
1 and 2/5 and 2 and 2/5
A fraction represented with its quotient and remainder is a mixed fraction. 1 2/5 and 2 2/5 are two mixed numbers that have a sum of 3 4/5.
What is Mixed Fraction?
A fraction represented with its quotient and remainder is a mixed fraction.
We need to find the two mixed numbers whose sum is 3 4/5.
The sum of two mixed numbers is 3 4/5 which is also equal to 19/5.
1 2/5+2 2/5
=7/5+12/5
=19/5
Now 3 4/5=19/5
Therefore 1 2/5 and 2 2/5 are two mixed numbers whose sum is 3 4/5

Answer:
He rented the bike for 6 hours.
Step-by-step explanation:
To solve this you would first subtract the initial amount which is $18 to $48. You would then divide 5 by $30 Since you have to pay $5 per hour, and you would end up with 6 which is the number of hours that willie rented the bike for.

Chris and Mary are selling tickets at their class play. Chris is selling student tickets for $4.00 each, and Mary selling adult tickets for $6.50 each. If their total income for 21 tickets was $124.00, how many tickets did Chris and Mary sell individually?
Answer:
Chris sells 5 tickets and Mary sells 16 tickets
Step-by-step explanation:
System of Equations
To solve the problem we call:
x = number of tickets sold by Chris
y = number of tickets sold by Mary
They sold a total of 21 tickets, thus:
x + y = 21 [1]
Mary sold adult tickets for $6.50 each and Chris sold student tickets for $4.00 each. The total income was:
4x + 6.5y = 124 [2]
Multiplying [1] by -4:
-4x - 4y = -84 [3]
Adding [2] and [3]:
2.5y = 40
Dividing by 2.5:
y = 40/2.5
y = 16
From [1]
x = 21 - 16 = 5
x = 5
Chris sells 5 tickets and Mary sells 16 tickets

The ratio of boys to girls in band class was 3 to 5. If there were 24 boys. How many girls were in band class?
Answer:
40 girls
Step-by-step explanation:
Set up a proportion where x is the number of girls in band class:
[tex]\frac{3}{5}[/tex] = [tex]\frac{24}{x}[/tex]
Cross multiply and solve for x:
3x = 120
x = 40
So, there were 40 girls in band class.
Answer: There are 40 girls in band class.
____________________________________________________________
The ratio for this problem is:
[tex]\frac{3}{5} = \frac{24}{x}[/tex]
To get from 3 to 24, you would multiply by 8. You need to do the same thing to 5 to get x.
5 times 8 equals 40.
There are 40 girls in band class.

solve for x, if m<2 = 2+6x
Answer:
x = 6
Step-by-step explanation:
Since the triangles are isosceles the two bottom angles are equal. So, 71 + 71 + 2 + 6x would help us find x. Now to solve it.
71 + 71 + 2 + 6x = 180
142 + 2 + 6x = 180
144 + 6x = 180
6x = 180 -144
6x/6 = 36/6
x = 6

Answer:
I believe the answer is C. 0.75
Step-by-step explanation:
The probability that at least one of the next five birds he sees is a robin is 0.75.
ProbabilityBased on the stimulation result shown on the table we can seen that other birds appeared at least 15 times.
Hence:
P(A)=15/20
P(A)=0.75
Therefore the probability that at least one of the next five birds he sees is a robin is 0.75.

Question:
Where are the equations?
the figure below is not drawn to scale. ABCD is a square. ACF and DCE are straight lines. Find ECF
Answer:
<ECF = 45 degrees
Step-by-step explanation:
If ABCD is a square, then the diagonal AC divides angle <C and angle <A in two equal parts. Angles A and C are also 90 degrees each due to the act that the figure is a square. Therefore their bisection would render 90/2 = 45 degrees.
Notice as well that angle <ECF is opposite by the vertex to one of these 45 degree angles, and then it must measure the same amount (45 degrees).
So, <ECF = 45 degrees
How do you use a protractor
Place the midpoint of the protractor on the VERTEX of the angle.
Line up one side of the angle with the zero line of the protractor (where you see the number 0).
Read the degrees where the other side crosses the number scale.

A professor at a local university noted that the exam grades of her students were normally distributed with a mean of 73 and a standard deviation of 11. A. The professor has informed us that 7.93 percent ofher students received grades of A. What is the minimum scoreneeded to receive a grade of A?B. Students who made 57.93 or lower on the exam failedthe course. What percent of students failed the course?C. If 69.5% of the students received grades of C or better, what is the minimum score of those who received C's?
Answer:
88.51
0.085343
67.39
Step-by-step explanation:
Given a normal distribution :
Mean (m) = 73
Standard deviation (s) = 11
Percentage A's = 7.93% = 0.0793
Minimum score needed to receive A :
Using the Z formula
Zscore corresponding to 0.0793 = 1.41
P(x ≥ x) :
Z = (x - m) / s
1.41 = (x - 73) / 11
11* 1.41 = x - 73
15.51 = x - 73
x = 15. 51 + 73
x = 88.51
B. Students who made 57.93 or lower on the exam failedthe course. What percent of students failed the course?
P(x ≤ 57.93)
Z = (x - m) / s
Z = (57.93 - 73) / 11
Z = - 15.07 / 11
Z = - 1.37
P( Z ≤ - 1.37) = 0.085343 ( Z probability calculator)
C.) If 69.5% of the students received grades of C or better, what is the minimum score of those who received C's?
Minimum score of those who received C
Zscore corresponding to 0.695 = -0.51 (Z probability calculator)
Z = (x - m) / s
-0.51 = (x - 73) / 11
11* - 0.51= x - 73
-5.61 = x - 73
x = - 5.61 + 73
x = 67.39
A large tank of fish from a hatchery is being delivered to a lake. The hatchery claims that the mean length of fish in the tank is 15 inches, and the standard deviation is 6 inches. A random sample of 46 fish is taken from the tank. Let x be the mean sample length of these fish. What is the probability that x is within 0.5 inch of the claimed population mean?
Answer:
0.4246
Step-by-step explanation:
Given data:
mean ( u ) = 15 inches
std ( б )= 6 inches
sample size( n ) = 46
ux = mean sample length
Determine the probability that x within 0.5 inch of the claimed population mean
ux = u = 15
бx = б/ √ 46 = 6 /√ 46 = 6 / 6.78 = 0.88
Hence the P( 14.5 < x < 15.5 )
= P ( [14.5 - 15 / 0.88 ] < z < (15.5 - 15) / 0.88) )
= P ( -0.5682 < z < 0.5682 )
= P ( z < 0.5682 ) - P ( z < -0.5682 )
= 0.7123 - 0.2877 ( from Z table )
= 0.4246
