Answer:
6 6 6 6 11
Step-by-step explanation:
The median is the middle number
the mode is the number of items, usually the number that are the same.
the mean is the average
the range is the number between the smallest and the largest.
So the information you have makes 4 of the 5 numbers the same.
The middle number is 6. This is an interesting fact because it means that 4 of the five numbers are 6
x 6 6 6 6 or 6 6 6 6 x is what you know so far.
The range is a bit of a devil. And so is the mean. We need the mean to be related to 5*7 = 35. So the sum of the five numbers equals 35. The range would have to be 5, I think. (35 - 4*6) = 11
The difference between 11 and 6 = 5
So 11 works for everything but the range.
If the range must be ten, then x = 16 but then the mean = 8 and 7 is incorrect
So I can get 3 out of 4, but not them all.

The television show September Road has been successful for many years. That show recently had a share of 20, meaning that among the TV sets in use, 20% were tuned to September Road. Assume that an advertiser wants to verify that 20% share value by conducting its own survey, and a pilot survey begins with 11 households have TV sets in use at the time of a September Road broadcast. Find the probability that none of the households are tuned to September Road. P(none)
Answer:
[tex]P(none) = 0.0859[/tex]
Step-by-step explanation:
Given
[tex]p =20\%[/tex] --- proportion of household that tuned to September
[tex]n =11[/tex] --- selected households
Required
[tex]P(none)[/tex]
Using the complement rule, the proportion that did not tune (q) is:
[tex]q= 1 - p[/tex]
[tex]q= 1 - 20\%[/tex]
[tex]q= 1 - 0.20[/tex]
[tex]q= 0.80[/tex]
So, the probability that none of the 11 tuned in is:
[tex]P(none) = q^{11}[/tex]
[tex]P(none) = 0.80^{11}[/tex]
[tex]P(none) = 0.0859[/tex]
Elizabeth ships a gift through the mail. The gift weighs 8 pounds 11 ounces. She packs the gift in a shipping box with bubble wrap. The package weighs 12 pounds 4 ounces. How much does the shipping box and bubble wrap weigh?
Answer:
3lbs 9 ounces
Step-by-step explanation:
16 ounces in a pound
9514 1404 393
Answer:
3 lb 9 oz
Step-by-step explanation:
Sometimes, addition is easier than subtraction when it comes to finding the difference.
There are 16 ounces in a pound.
8 lb 11 oz + 5 oz = 9 lb
9 lb + 3 lb 4 oz = 12 lb 4 oz
To get from 8 lb 11 oz to 12 lb 4 oz, we have added ...
5 oz + 3 lb 4 oz
= 3 lb 9 oz . . . . weight of packing materials
__
Or, you can do the subtraction in the usual way.
total weight = gift weight + packing weight
packing weight = total weight - gift weight
= (12 lb 4 oz) - (8 lb 11 oz)
= (12 lb -8 lb) + (4 oz -11 oz)
= 4 lb - 7 oz
packing weight = 3 lb 9 oz

Susan buys the items listed below at a grocery store. 2 packages of chicken priced at $13.26 per package 1/2 pound of broccoli priced at $ 1.88 per pound 1 gallon of milk priced at $3.49 per gallon There is no sales tax on the food she buys. Susan pays for the items and receives $ 0.05 in change. What amount of money does Susan use to pay for the items?
Answer: $31.00
Step-by-step explanation:
The cost of the items bought will be:
2 packages of chicken priced at $13.26 per package = 2 × $13.26 = $26.52
1/2 pound of broccoli priced at $ 1.88 per pound = 1/2 × $1.88 = $0.94
1 gallon of milk priced at $3.49 per gallons = 1 × $3.49 = $3.49
Since Susan pays for the items and receives $ 0.05 in change, the the amount of money that Susan use to pay for the items will be:
= $26.52 + $0.94 + $3.49 + $0.05
= $31.00
The amount Susan uses in paying is $31.00.
If JK = 4, KL = 3x, and JL = 7x, what is JL? Simplify your answer and write it as a proper fraction, mixed number, or integer.
Answer:
JL = 7
Step-by-step explanation:
If JK = 4, KL = 3x, and JL = 7x, what is JL?
From the diagram given in tbe question,
JK + KL = JL
4 + 3x = 7x
Collect like terms
4 = 7x - 3x
4 = 4x
4x = 4
x = 4/4
x = 1
Since JL from the diagram = 7x
Hence:
7 × 1 = 7
JL = 7

Whats the last info I need?
Answer:
Step-by-step explanation:
Properties of the similarity of two triangles,
1). Corresponding angles of two triangles should be equal.
2). Corresponding sides of two triangles should be proportional.
By applying second property in the given triangles RTY and CVB,
[tex]\frac{CV}{RT}=\frac{TY}{VB}=\frac{CB}{RY}[/tex]
[tex]\frac{15}{10}= \frac{9}{6}= \frac{CB}{RY}[/tex]
[tex]1.5= 1.5= \frac{CB}{RY}[/tex]
Ratio of sides CB and RY should be 1.5 for the similarity of two triangles.
Therefore, additional information required for the similarity of two triangles is "the measure of third sides of both the triangles should be known"

I. Tell whether each statement is TRUE or FALSE. Refer to the figure below. Write your answer on the space provided.
Answer:
1. TRUE
2. TRUE
3. TRUE
4. TRUE
5. FALSE
6. TRUE
Step-by-step explanation:
1. From the diagram, we have that m∠2 and m∠7 are alternate interior angles
If m∠2 = 70° and m∠7 = 70°, then we have;
m∠2 = 70° = m∠7
m∠2 = m∠7
Therefore, the alternate interior angles of the lines l₁, and l₂ are equal, and therefore, the lines l₁ and l₂ are parallel, l₁ ║ l₂
TRUE
2. If m∠3 = 90° and m∠7 = 90°, therefore, the angle formed by the intersection of l₃ and l₂ = 90°
Therefore l₃ ⊥ l₂
TRUE
3. m∠5 and m∠7 are corresponding angles
If m∠5 = 85° and m∠7 = 85°, then, m∠5 = m∠7
Therefore, the corresponding angles formed by the lines l₁ and l₂ are equal, therefore;
l₁ ║ l₂
TRUE
4. Whereby we have, m∠1 = m∠5, we get;
m∠1 + m∠5 = 180° by sum of angles on a straight line
∴ m∠1 + m∠5 = m∠1 + m∠1 = 2·m∠1 = 180°
m∠1 = 180°/2 = 90°
∴ m∠1 = 90° = m∠5, and l₃ ⊥ l₁
TRUE
5. m∠1 and m∠8 are alternate exterior angles
If m∠1 = 98° and m∠8 = 82°
∴ m∠1 ≠ m∠8 and l₁ ∦ l₈
FALSE
6. Given that l₁║ l₂, then the angle formed between l₁ and l₃ will be equal to th angle formed between l₂ and l₃
Therefore;
If l₁║ l₂, and l₃ ⊥ l₁, then l₃ ⊥ l₂
(If l₁║ l₂, and l₃ is perpendicular to l₁, then l₃ is also perpendicular to l₂)
TRUE

value of x, the cost of each cavity filling?
Answer:
The cost of each cavity filling was $ 134.60.
Step-by-step explanation:
Given that the total cost of Anfa's trip to the dentist was $ 628.35, and she paid a flat fee of $ 89.95 which included the checkup: cleaning and then had 4 cavities filled, each of which cost the same amount, to determine which shows the correct equation and value of x, the cost of each cavity filling, the following calculation must be performed:

Write two solutions for the following equation 2x+3y=24.
Answer: (12, 0) and (0, 8)
Step-by-step explanation:
This equation is in standard form. We can sub in a number for x to solve for y and vice versa.
Let's sub in 0 for x.
[tex]2x+3y=24\\2(0)+3y=24\\3y=24\\\frac{3y}{3} =\frac{24}{3} \\y=8[/tex]
When x is 0 y is 8 giving us the coordinate (0, 8).
Now lets sub in 0 for y
[tex]2x+3(0)=24\\2x=24\\\frac{2x}{2} =\frac{24}{2} \\x=12[/tex]
When y is 0 x is 12 giving us the coordinate (12, 0)
Step-by-step explanation:
Begin by solving for y
3y = -2x + 24 divide by 3
y =-(2/3)x + 24
Choose x so that it is divisible by 3
Let x = 6 which 3 can divide into evenly
y = -(2/3)*6 + 24 3 into 6 is 2 so you are left with
y = - 2 * 2 + 24
y = - 4 +24
y = 20
By a similar mthed, let x = 15
y = -2/3 x + 24
y = -2/3 * 15 +24
y = -2 * 5 + 24
y = -10 + 24
y = 14
So your two solutions are
