The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 30 hours and the median is 26.2 hours. Twenty-four of the families in the sample turned on the television for 15 hours or less for the week. The 11th percentile of the data is 15 hours. Step 4 of 5 : What is the value of the 50th percentile?
Answer:
26.2 hours
Step-by-step explanation:
From the given information:
The objective is to determine the value of the 50th percentile.
The median is the 50th percentile, which categorically divides the data into two equal parts. It is a number separating the higher half of a data sample from the lower half. This implies that the median stands in place for the 50th percentile of the data.
Thus, the 50th percentile value is 26.2 hours

Step-by-step explanation:
A mile equals 1,760 yards. 2.5 times 1,760 gives you 4,400
It is given that A class walked 2.5 miles for a walk-a-thon then the class walked 4400 yards.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
It is given that A class walked 2.5 miles for a walk-a-thon.
WE are asked How many yards did the class walk.
A mile equals 1,760 yards.
If one mile is 1760 yards, then the answer should be
= 1760 times the number of miles.
So 1760*2.5 = 4400

10 oranges and 20 grapefruits weigh 35 pounds total. 16 oranges and 10
grapefruits weigh 23 pounds total. How much would 13 oranges and 15
grapefruits weigh?
A 28 pounds
B 29 pounds
C 30 pounds
D 58 pounds
Answer:
B
Step-by-step explanation:
oranges weigh 0.5 and grapefruits weigh 1.5
The required: 13 oranges and 15 grapefruits would weigh 29 pounds.
The correct option is A.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously are called simultaneous equations. And the simultaneous equation is the system of equations.
Let's use a system of equations to solve this problem:
Let's call the weight of an orange "x" and the weight of a grapefruit "y". Then we can write:
10x + 20y = 35 (equation 1)
16x + 10y = 23 (equation 2)
We want to find the weight of 13 oranges and 15 grapefruits, which we can represent as:
13x + 15y
In this case, we can multiply equation 1 by -8 and equation 2 by 15:
-80x - 160y = -280 (equation 1, multiplied by -8)
240x + 150y = 345 (equation 2, multiplied by 15)
Now we can add the two equations to eliminate y:
160x = 65
Solving for x, we get:
x = 65/160
Now we can substitute this value of x back into one of the original equations to solve for y. Let's use equation 1:
10(65/160) + 20y = 35
Simplifying this equation, we get:
13/32 + 2y/4 = 7/2
Multiplying both sides by 32, we get:
13 + 16y = 112
Solving for y, we get:
y = 99/16
Finally, we can substitute these values of x and y into the expression for 13 oranges and 15 grapefruits:
13x + 15y = 13(65/160) + 15(99/16) = 29.0625
Therefore, 13 oranges and 15 grapefruits would weigh approximately 29.0625 pounds, which is closest to answer B, 29 pounds.

Solve 2х + 4 > 16.
А. x> 6
В. x<10
C. x> 10
D. х< 6
Answer:
The answer is x > 6.
Reasoning:
2x + 4 > 16You have to subtract 4 from both sides:2x + 4 > 16
-4 > -4
2x > 12
16 subtract from 4 is 12. You then divide the 12 by the 2.2x > 12

x > 6

2.) -3(8+3h)=5h+4
3.) 2(y-6)=3(y-4)-y

Answer:
1. [tex]x[/tex] = 9
2. [tex]h[/tex] = 2
3. Infinitely Many Solutions
4. No solution
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
1.) 5(2[tex]x[/tex] + 6) = 8[tex]x[/tex] + 48
Step 1: Expand.
10[tex]x[/tex] + 30 = 8
Step 2: Subtract 30 from both sides.
10[tex]x[/tex] = 8
Step 3: Simplify 8[tex]x[/tex] + 48 − 30 to 8[tex]x[/tex] + 18.
10[tex]x[/tex] = 8
Step 4: Subtract 8[tex]x[/tex] from both sides.
10[tex]x[/tex] − 8
Step 5: Simplify 10[tex]x[/tex] − 8[tex]x[/tex] to 2[tex]x[/tex].
2[tex]x[/tex] = 18
Step 6: Simplify [tex]\frac{18}{2}[/tex] to 9.
[tex]x[/tex] = 9
2.) −3(8 + 3[tex]h[/tex]) = 5[tex]h[/tex] + 4
Step 1: Expand.
−24 − 9[tex]h[/tex] = 5
Step 2: Add 24 to both sides.
−9[tex]h[/tex] = 5
Step 3: Simplify 5[tex]h[/tex] + 4 + 24 to 5[tex]h[/tex] + 28.
−9[tex]h[/tex] = 5
Step 4: Subtract 5[tex]h[/tex] from both sides.
−9[tex]h[/tex] − 5
Step 5: Simplify −9[tex]h[/tex] − 5[tex]h[/tex] to −14[tex]h[/tex].
−14[tex]h[/tex] = 28
Step 6: Divide both sides by −14.
[tex]h[/tex] = [tex]-\frac{28}{14}[/tex]
Step 7: Simplify [tex]\frac{28}{14}[/tex] to 2.
[tex]h[/tex] = 2
3.) 2([tex]y[/tex] − 6) = 3([tex]y[/tex] − 4) − [tex]y[/tex]
Step 1: Expand.
2[tex]y[/tex] − 12 = 3
Step 2: Simplify 3[tex]y[/tex] − 12 − [tex]y[/tex] to 2[tex]y[/tex] − 12.
2[tex]y[/tex] − 12 = 2 − 12
Step 3: Since both sides equal, there are infinitely many solutions.
Infinitely Many Solutions
4.) 8[tex]x[/tex] − 4 = 2(4[tex]x[/tex] − 4)
Step 1: Expand.
8[tex]x[/tex] − 4 = 8
Step 2: Cancel 8[tex]x[/tex] on both sides.
−4 = −8
Step 3: Since −4 = −8 − 4 = −8 is false, there is no solution.
No solution

Amelia and her brother had a snow day, so they played in the snow for 3 hours. During that time, it snowed another 4.8 inches. If the snow fell at a steady pace, how much snow fell each hour?
Answer:
1.6
Step-by-step explanation:
The amount of snow fell each hour is 1.6 inches per hour.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
In other words it compares 1 unit of some quantity with different amount of another quantity
Given that,
Time Amelia and her brother played in the snow = 3 hours
Amount of snow fell at that time = 4.8 inches
That is 4.8 inches of snow per 3 hours
We have to calculate the unit rate of the amount of snow falling in an hour.
Amount of snow in 1 hour = 4.8 / 3 = 1.6 inches per hour
Hence the 1.6 inches of snow is falling per hour.

Answer:
Number of times Jenna feeds her cat = 2
Cat food each time
Number of days = 5
Number of cans she bought = 8
Step-by-step explanation:

Sabendo que as retas r, s e t são paralelas, determine o valor de x na imagem a seguir
a)3
b)3,2
c)3,5
d)4
Answer:
x = 3.2
Step-by-step explanation:
Aquí, queremos encontrar el valor de x en la imagen de arriba.
Matemáticamente eso sería;
x / 4 = (x + 16) / (20 + 4)
x / 4 = (x + 16) / 24
Cruz multiplicar 24 * x = 4 (x + 16)
24x = 4x + 64
24x - 4x = 64
20x = 64
x = 64/20 x = 3,2
From the transversal proportionality theorem of parallel lines r,s,t. the value of x is 3.2.
It is given that r, s, t are parallel to each other. The length of the sides is given as 16, 20, 4, x. we need to find the value of x.
What is the transversal proportionality theorem?If two or more parallel lines are cut by two transversals, then they divide the transversals proportionally.
From the transversal proportionality theorem,
When r, s, t are parallel to each other then a / x = b / y
so,
[tex]\rm \frac{16}{x} = \frac{20}{4} \\\rm x = \frac{16}{5} \\\rm x = 3.2[/tex]
Therefore, from the transversal proportionality theorem of parallel lines r,s,t. the value of x is 3.2.
