The data modeled by the box plots represent the battery life of two different brands of batteries that Mary tested. (a) What is the median value of each data set? (b) Compare the median values of the data sets. What does this comparison tell you in terms of the situation the data represent? For 100 point pls
Answer:
a brand x = 13 (median ) brand y = 16 median
Answer:
A) Median value is depicted on a box plot by the vertical line that divides the rectangular box. Therefore: Median value for Brand X = 13 and Median value for Brand Y = 16. B) Brand Y has a higher median value (16) than Brand X (13). This implies that brand Y has a battery life that last longer than brand X.
PLEASE HELP I DONT UNDERSTAND!!! Mason works in a cell phone store where he earns a base salary of $105 per a day plus 15% of his sales. He earned $600 by working on a Saturday and Sunday and sold the same amount on both days. Select all of the statements that help explain how to find his sales for each day.
A. Mason's base salary is $105, so over the 2 days he earned $210.
B. Subtract $210 from $600 to find he made $390 on sales.
C. Mason's base salary is $600, so over the two days he earned $1,200.
D. Multiply $390 by 0.15 to find he sold $58.50 worth of cell phones. Divide $58.50 by 2 to find he sold $29.25 worth of cell phones each day.
E. Divide $390 by 0.15 to find he sold $2,600 worth of phones. Divide $2,600 by 2 to find he sold $1,300 worth of phones each day.
F. Add $1,200 to $105 to find Mason made $1,305 on phone sales.

What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Dwayne watched a movie that began at 4:38 p.m. The movie finished at 6:22 p.m.
Now, The length of movie watched by Dwayne is,
⇒ 6 : 22 - 4 : 38
⇒ 1 : 84
⇒ 2 : 24
Hence, The movie would be 2 hours 24 minutes long.

Using the exponential growth function for the U. S. population from 1970 through 2003:

with the U.S. population being 205.1 million in 1970,
when would the U. S. population reach 350 million?

Answer:
Step-by-step explanation:
Using the exponential growth function for the U. S. population from 1970 through 2003:
A = 205.1e^0.011t
with the U.S. population being 205.1 million in 1970, when would the U. S. population reach 350 million?
A.
2028
B.
2048
C.
2018
D.
2038
We have the expression
A = 205.1e^0.011t
We are asked to find when would the U. S. population reach 350 million
A = 350
350 = 205.1e^0.011t
We divide both sides by 205.1
Divide both sides by 205.1
350/205.1 = 205.1e^0.011t/205.1
1.7064846416 = e^0.011t
We take the log of both sides
log 1.7064846416 = log e^0.011t
log 1.7064846416 = t log 0.011
t = log 1.7064846416/ log 0.011
t = 0.1185057826

A store has clearance items that have been marked down by 55%. They are having a sale advertising an additional 25% off clearance items. What % of the original price do you end up paying
Answer: 33.75%
Step-by-step explanation:
The items were marked down by 55% from their original price.
This means that the new price is:
= 1 - Percentage marked down
= 1 - 55%
= 45% of the original.
From this 45%, additional percentage of 25% is removed from this amount. The amount left will be:
= 45% * ( 1 - 25%)
= 33.75%

An engineer needs to determine the distance across a river without swimming to the other side. The engineer notices a tree on the other side of the river and suddenly has an idea.
Describe how she will sketch her idea to be able to determine the distance. Make a sketch and support you figure by number use meter as unit.
Answer:
Step-by-step explanation:
The engineer can use a clinometer to measure the angle of elevation of the top of the tree. Let the height of the tree be represented by x, the she could determine the distance across the river, d, by applying the trigonometric function.
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
= [tex]\frac{x}{d}[/tex]
the the distance, d = x ÷ Tan θ
Assume the angle of elevation of the top of the tree is [tex]30^{o}[/tex], and the height of the tree is 10 m, then the distance, d, across the river would be;
d = [tex]\frac{10}{0.5774}[/tex]
= 17.3190
d = 17.32 m

Pierre was plotting the quadratic function f(x) = - x ^ 2 + 8x for an exit ticket His work is shown below .
Answer:
(a) The table
[tex]\begin{array}{cc}x & {f(x)} & {0} & {0} & {1} & {7}& {2} & {12} & {3} & {15} & {4} & {16} & {5} &{15} & {6} & {12} & {7} &{7} & {8} & {0}\ \end{array}[/tex]
(b) See attachment for graph
(c) He swapped the values of the x and y coordinates for one another
Step-by-step explanation:
Given
See attachment for complete question
Solving (a): Complete the table
[tex]f(x) = -x^2 + 8x[/tex]
[tex]x = 0[/tex]: [tex]f(0) = -0^2 + 8*0 = 0 + 0 = 0[/tex]
[tex]x = 1[/tex]: [tex]f(1) = -1^2 + 8*1 = -1 + 9 = 7[/tex]
[tex]x = 2[/tex]: [tex]f(2) = -2^2 + 8 *2 = -4 + 16 = 12[/tex]
[tex]x = 3[/tex]: [tex]f(3) = -3^2 + 8 *3 = -9 + 24 = 15[/tex]
[tex]x = 4[/tex]: [tex]f(4) = -4^2 + 8 *4 = -16 + 32 = 16[/tex]
[tex]x = 5[/tex]: [tex]f(5) = -5^2 + 8 *5 = -25 + 40 = 15[/tex]
[tex]x = 6[/tex]: [tex]f(6) = -6^2 + 8 *6 = -36 + 48 = 12[/tex]
[tex]x= 7[/tex]: [tex]f(7) = -7^2 + 8 *7 = -49 + 56 = 7[/tex]
[tex]x = 8[/tex]: [tex]f(8) = -8^2 + 8 *8 = -64 + 64 = 0[/tex]
So, the complete table is:
[tex]\begin{array}{cc}x & {f(x)} & {0} & {0} & {1} & {7}& {2} & {12} & {3} & {15} & {4} & {16} & {5} &{15} & {6} & {12} & {7} &{7} & {8} & {0}\ \end{array}[/tex]

Jonathan has 25 coins in his pockets and they are all either nickels or quarters. If he has a total of
$3.25, how many of the coins are nickels and how many are quarters. Give me two equations and the answer in nickels and quarters
Answer:
The answer is 10 quarters and 15 nickels
Step-by-step explanation:
Lets say x equals the number of quarters and y quals the number of nickels. Since there is a total of 25 coins that means that x+y=25. But, the quarter costs 0.25, and the nickel costs 0.05. That means that we have to multiply the number of each coin with their cost. Which leads us to: (x*0.25)+(y*0.05)=3.25. By solving these two equations you'll see that x=10 and y=15.

(c) Find the value of P when w = 2 and y = 4
Answer:
p=-6
Step-by-step explanation:
w =2 y =4
p=7w - 5y
p = 7(2) - 5(4)
p= 14 - 20
p= -6
Answer:
-6
Step-by-step explanation:
Substituting 2 for w and 4 for y, we get:
P=7w - 5y => P=7(2) - 5(4) = 14 - 20 = -6
If a tank leaks 10 mL of fluid each hour, how long will it take to fill up a one-litre jar?
10 hours
1,000 hours
1 hour
100 hours
Answer:
100 hours
Step-by-step explanation:
To find the amount of liters in one hour, you divide 10 by 1000, which gives 0.01 liters each hour. From here, the 1 is in the hundredths place, so if you multiply by 100 hours, if will be at 1 liter.
The diagonal of a rectangle frame is 8 inches and the width of the frame is 6 inches. What is the length of this frame in inches?
Answer:
5.3 inches
Step-by-step explanation:
The diagonal of a rectangle frame is 8 inches and the width of the frame is 6 inches. What is the length of this frame in inches?
Diagonal² = Length² + Width²
Length = √Diagonal² - Width
= √8² - 6²
= √64 - 36
= √(28)
Length = 5.2915026221 inches
Approximately = 5.3 Inches
