777,498,619,379,895,1,256,1052 a. What is the mediam of the first half of data?(first quatile. b. What's the mediam of second half of the data?(third quartile) c. What is the interquartile range ?
Answer:
[tex]Q_1 = 498[/tex]
[tex]Q_3 =1052[/tex]
Step-by-step explanation:
Given
[tex]Data: 777,\ 498,\ 619,\ 379,\ 895,\ 1,256,\ 1052[/tex]
[tex]n = 7[/tex]
First, the data has to be arranged:
[tex]Data: 379,\ 498,\ 619,\ 777,\ 895,\ 1052,\ 1256[/tex]
Solving (a): Lower Quartile
This is calculated as:
[tex]Q_1 =\frac{1}{4} * (N + 1)th[/tex]
[tex]Q_1 =\frac{1}{4} * (7 + 1)th[/tex]
[tex]Q_1 =\frac{1}{4} * 8th[/tex]
[tex]Q_1 = 2nd[/tex]
The 2nd data is 498
Hence:
[tex]Q_1 = 498[/tex]
Solving (b): Third Quartile
This is calculated as:
[tex]Q_3 =\frac{3}{4} * (N + 1)th[/tex]
[tex]Q_3 =\frac{3}{4} * (7 + 1)th[/tex]
[tex]Q_3 =\frac{3}{4} * (8)th[/tex]
[tex]Q_3 =6th[/tex]
The 6th data is 1052
Hence:
[tex]Q_3 =1052[/tex]
Solving (c): Interquartile Range
This is calculated as:
[tex]IR = Q_3 - Q_1[/tex]
[tex]IR = 1052- 498[/tex]
[tex]IR = 554[/tex]
Over a three-week period, Abram spent 15
hours practicing the piano. If he keeps the
same schedule, how many hours will he spend
practicing in the next 4 weeks?
Answer:
20 hours
Step-by-step explanation:
First off, if we divide the number of hours he has played by the number of weeks 15/3 =
It would be an average of 5 hours per week
Therefore, in the next 4 weeks we would practice for 20 more hours.

Find the value of if the perimeter of the rectangle is 30inches. The length is 2x + 3and the width is x
Answer:
The perimeter of a rectangle is 30 meters. The length of the rectangles is 3 meters more than twice the width. Find the dimensions of the rectangle.
Step-by-step explanation:
Equation for Perimeter of a rectangle: Perimeter = 2W + 2L
Defining the variables, let
Width = x
Length = 2x+3 (3 more than twice the width)
Plugging everything into the equation
30= 2(x) + 2(2x+3) using the distributive property,
30=2x+4x+6 combining like terms
30=6x+6 subtracting 6 from both sides,
24=6x divide both sides by 6
4=x This means that the width is 4 m
To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved for
L=2(4)+3
L=8+3 = 11 m
So the dimensions of the rectangle are width is 4 m and length is 11 m

4medical : relating to or being transmission (as of a disease) by genetic inheritance or by a congenital or perinatal routeChoose the Right Synonym for vertical
VERTICAL, PERPENDICULAR, PLUMB mean being at right angles to a base line. VERTICAL suggests a line or direction rising straight upward toward a zenith. the side of the cliff is almost vertical PERPENDICULAR may stress the straightness of a line making a right angle with any other line, not necessarily a horizontal one. the parallel bars are perpendicular to the support posts PLUMB stresses an exact verticality determined (as with a plumb line) by earth's gravity. make sure that the wall is plumb

Part A: Determine the scale factor.
Part B: Solve for the unknown variable of the larger floor.
Answer:
show stage and back stage
Step-by-step explanation:
The scale factor is 3 and the value of the unknown variable of the larger floor is 36 ft and this can be determined by using the given data.
Given :
Two-stage floors are in the shape of isosceles trapezoids. The small stage floor in the drama room is geometrically similar to the large stage floor in the auditorium.a) Let the scale factor be 'y'. So, the value of 'y' can be calculated as:
[tex]\begin{aligned}\\24 &= y \times 8\\y &= 3\\\end{aligned}[/tex]
So, the scale factor is 3.
b) The value of the unknown variable of the larger floor is calculated as:
[tex]\begin{aligned} \\12\times y &= x\\12\times 3& = x\\x&= 36\\\end{aligned}[/tex]
So, the value of the unknown variable of the larger floor is 36 ft.

yokoreceived a 70 gift card for a coffee store. She used it in buying some coffee that cost 8.04 per pound. After buying the coffee, she had 45.88 left on her card. How many pounds of coffee did she buy?
Answer:
Since she started with $80 and ended with with $35,24, we can find the total amount she spent by subtracting these amounts:
$80 - $35.24 = $44.76
This means that she spent $44.76 on coffee. If each pound cost $7.46, we can divide $44.76 by $7.46 to see how many pounds she bought (ignoring tax):
44.76 / 7.46 = 6 pounds of coffee purchased

Answer: 3 13/24
Step-by-step explanation:
First off we have an issue with the problem due to denominators not being the same
So we need to find a common denominator
The common denominator would be 24 for 6 and 8
Then we must multiply the numerator 1 by 4 and the numerator 3 by 3
Our new problem would look like

Pasha works as a food scientist. He designed a recipe for crackers that are 65% wheat flour by weight. He made a test batch of the crackers from 1 1/4 total pounds of ingredients. What weight of wheat flour did Pasha use in the test batch?
Weight of wheat flour = percentage of wheat in the recipe x total pounds of ingredients
the first step is to convert 65% to a fraction. To do this, express 65 as a fraction of 100 and express the fraction in its lowest term
[tex]\frac{65}{100}[/tex]
Dividing the numerator and denominator by 5 gives
[tex]\frac{13}{20}[/tex]
