Hey There!
To find the range you subtract the largest number from the smallest number. In this data plot it seems that the largest number is 85 and the lowest number is 15
85-15=70
Therefore the range is 70
Answer:
The range is the largest number minus the smallest number.
85 - 15 = 70

Two consecutive integers have a sum of 75. Find the integers.
Answer:
37 and 38
Step-by-step explanation:
let the consecutive integers be x-1 and x
If their sum is 75
x-1+x = 75
2x - 1 = 75
2x = 75+1
2x = 76
x = 76/2
x = 38
First integer = x - 1
First integer = 38-1 = 37
Second integer is 38
Hence the integers are 37 and 38

Damien needs to order more pill containers for the pharmacy. Currently, there are 156 8-dram bottles, 78 20-dram bottles, and 132 30-dram bottles. All the bottles come in cases of 140 bottles. The pharmacist wants all stocks to be replenished so that there are at least 400 of each bottle type. How many cases of each bottle type does Damien need to order
Answer:
for 8 gram bottle = 2 cases
for 20 gram bottle = 3 cases
for 30 gram bottles = 2 cases
Step-by-step explanation:
Determine how many cases of each bottle type Damien needs to order
i) For 8-gram bottles
available bottles = 156
required amount ≥ 400
extra bottles to be ordered = 400 - 156 = 244 bottles
since case contains 140 bottles , the number of cases to be ordered
= 244 / 140 = 1.74 cases ≈ 2 cases
ii) for 20 gram bottles
available bottles = 78
required amount ≥ 400
Extra bottles to be ordered = 400 - 78 = 322 bottles
therefore the number of cases = 322 / 140 = 2.3 cases ≈ 3 cases
iii) For 30 gram bottles
available bottles = 132
required amount ≥ 400
Extra bottles to be ordered = 400 - 132 = 268
therefore the number of cases = 268 / 140 = 1.9 ≈ 2 cases
How many ways can 14 students line up in 8 positions if the third,
fourth, and fifth positions must be student x, y or z?
Answer:
Step-by-step explanation:
Using the permutation formula, it is found that there are 55,440 ways for the students to line up.
The order in which the students line up is important, hence the permutation formula is used to solve this question.
What is the permutation formula?The number of possible permutations of x elements from a set of n elements is given by:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this problem, 3 positions are set, and the remaining 11 students will be selected for 5 positions, hence:
[tex]P_{(11,5)} = \frac{11!}{6!} = 55440[/tex]

The equation that produces the circle in the given graph is; x² + y² = 16
How to interpret the equation of a Circle?
The general form of equation of a circle is;
(x - h)² + (y - k)² = r²
where;
h, k are coordinates of the circle center
r is the radius
From the graph, we can see that the coordinates of the center is; (0, 0).
Also, radius is;
r = √(4² - 0²)
r = √16
Thus, our equation of the circle in the graph is;
(x - 0)² + (y - 0)² = (√16)²
⇒ x² + y² = 16

what happens to mean amd median?
Step-by-step explanation:
.
Answers:
Part (a): It stays the samePart (b): It decreases by 5 dollars=====================================================
Explanation:
Part (a)
The numbers are sorted from smallest to largest, so we pick out the middle most value to get the median. It turns out that 1015 and 1025 are tied for the middle-most spot. Average these values to get (1015+1025)/2 = 1020. The median is 1020.
Notice how the median will not change if we replaced one "1100"s with "1060". This is because 1015 and 1025 still occupy the middle, and 1020 is at the midpoint between them. The median would only change if we either introduce or take away a value entirely, or if we replaced 1100 with some value between 1015 and 1025 that isn't 1020 itself. For instance, if we replace 1100 with 1019, then the median would become 1017 (decrease).
However, none of these situations happen, so that's why the median stays where it is.
--------------------------
Part (b)
Go back to the original list of numbers.
Add them up to get
820+910+945+1015+1025+1085+1100+1100 = 8000
Divide this over 8 since we have 8 values here
8000/8 = 1000
The mean rent is $1000
Now let's replace one copy of the "1100" with "1060". Follow the same steps as above.
Add: 820+910+945+1015+1025+1085+1060+1100 = 7960Divide: 7960/8 = 995After that rent change from $1100 to $1060, the mean rent is now $995
The mean rent went down by 1000-995 = 5 dollars.

If a hockey player takes 78 shots and scores 16 goals, what would be the probability of this player scoring a goal on their next shot?
0.173
0.205
0.013
0.263
Answer:
0.205
Step-by-step explanation:
This is a question of experimental probability, in which the probability from the previous outcomes is the probability for the next outcome.
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this question:
16 goals on 78 shots. So the probability of the player scoring a goal in the next shot is:
16/78 = 0.205

Answer:
The solution to the equation is [tex]x = 8[/tex]
Step-by-step explanation:
To solve the equation, first we apply the distributive property on the parenthesis, then we isolate x.
Solution:
[tex]3(10 - x) = 6[/tex]
Applying the distributive:
[tex]3*10 - 3*x = 6[/tex]
[tex]30 - 3x = 6[/tex]
Solving for x
[tex]3x = 30 - 6[/tex]
[tex]3x = 24[/tex]
[tex]x = \frac{24}{3}[/tex]
[tex]x = 8[/tex]

consider the figure shown below. Match the angles given in the first column with their equivalent degree Measure given in the first row
Answer:
∠3 = 115°
∠8 = 75°
∠6 = 105°
∠11 = 115°
∠9 = 65°
∠4 = 65°
Step-by-step explanation:
∠3 = 180 - 65 =115° because they are supplementary
∠8 = 75° because it is vertical to 75°
∠6 = 180 - 75 = 105° because they are supplementary
∠11 = 115° because it is corresponding to ∠3
∠9 = 65° because it is corresponding to ∠1
∠4 = 65° because it is vertical to 65°
Applying the definition of special angle pairs, the given angles and their respective equivalent degree measures are:
m<3 = 115°m<8 = 75°m<11 = 115°m<9 = 65°m<4 = 75°Given the following:
m<1 = 65°m<5 = 75°Thus:
<3 and <1 are supplementary angles, therefore,
m<3 = 180° - 65°
m<3 = 115°
<8 and <5 are vertical angles, therefore,
m<8 = 75°
<6 and <8 are supplementary angles, therefore,
m<6 = 180° - 75°
m<6 = 105°
<11 and <3 are corresponding angles, therefore,
m<11 = 115°
<9 and <1 are corresponding angles, therefore,
m<9 = 65°
<4 and <2 are vertical angles, therefore,
m<4 = 75°
