In which branch of statistics would a researcher acquire twenty-five 2000 Toyota Celicas, drive them until they had a major mechanical failure, record the final mileage, and then write a report for Car and Driver?
Answer:
The answer is "descriptive statistics".
Step-by-step explanation:
Descriptive statistics are short descriptive factors that add up a production set, that can be either a reflection of a whole or a sample population. It is broken down into cumulative frequency measurements and variance measurements. The study uses descriptive statistics to explain the profile of the respondents. People give simple summaries about the sample as well as the actions.

Step-by-step explanation: To handle these evaluation problems, you must be able to deal with positives and negatives, and you must know your order of operations. In addition, it's a good idea to get into the habit of using parenthses when substituting numbers in for variables.
Notice that we have a set of parenthses in our problem and remember that we use parenthses when substituting our numbers into the problem.
To avoid the confusion of having too many sets of parenthses,
let's change the parenthses in the original problem to brackets.
Now let's substitute using parenthses.
So we have (5)² · [(9) - (3)].
Since the parenthses were in the original problem were replaced
by brackets and parenthses come first in your order of operations,
in our problem the brackets are going to come first.
So first simplify 9 - 3 which is 6.
So we have (5)² [(6)].
Exponents come next so we square the 5 to get 25
and that gives us (25) [(6)] which is 150.
Find the value of x.
Answer:
The value of x is 120°
Step-by-step explanation:
We should draw a line parallel to the given parallel lines and passes through the vertex of the measure x and divides it into two angles of measures x1 and x2, look at the attached figure
In the given figure
∵ The dashed line is parallel to the given line up
∴ The angle of the measure 70° and the angle x1 are alternate angles
∵ The alternate angles are equal in measures
∴ x1 = 70°
∵ The dashed line is parallel to the given line down
∴ The angle of the measure 50° and the angle x2 are alternate angles
∵ The alternate angles are equal in measures
∴ x2 = 50°
∵ x = x1 + x2
∴ x = 70 + 50
∴ x = 120°
∴ The value of x is 120°
Answer:
x= 120
Step-by-step explanation:
Alternated angles are 50 and 70

A health food store sells a mixture of raisins and roasted nuts.
Raisins sell for $4.00/kg and nuts sell for $6.00/kg. How many
kilograms of each should be mixed to make 40 kg of this snack
worth $4.75/kg?
Raisins= ?kg
Nuts= ?kg
Answer:
Raisins = 25 kg
Nuts = 15 kg
Step-by-step explanation:
Given that:
Kilograms of snack to be made = 40 kg
Price per kg would be $4.75kg.
Price of 40 kg would be = 4.75 * 40 = $190
Let,
x be the kilograms of raisins
y be the kilograms of nuts
According to given statement;
x+y=40 Eqn 1
4.00x+6.00y=190 Eqn 2
Multiplying Eqn 1 by 4
4(x+y=40)
4x+4y=160 Eqn 3
Subtracting Eqn 3 from Eqn 2
(4x+6y)-(4x+4y)=190-160
4x+6y-4x-4y=30
2y=30
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{30}{2}\\y=15[/tex]
Putting y=15 in Eqn 1
x+15=40
x=40-15
x=25
Hence,
Raisins = 25 kg
Nuts = 15 kg
Answer:
the answer is
raisins= 25 kg
nuts= 15 kg

A store is having a 20% off sale on all merchandise 1. If Mai buys one item and saves $13 what was the original price
Answer: $65
Step-by-step explanation:
The store is having a 20% off sale.
Mai buys an item and saves $13.
This means that $13 is 20% of the price of the item that Mai bought.
Assume the original price is x. Expression is:
x * 20% = 13
x = 13/20%
x = $65

Elena paints the back of a aquarium it has a height of 1 3/4 feet the painted area is 5 5/6 what is the length
Answer:
3 1/3 feets
Step-by-step explanation:
Given that:
Height of aquarium = 1 3/4 feets
Area of aquarium = 5 5/6 ft²
The length of aquarium = x
Aquarium is shaped in the form of a rectangle :
Area of a rectangle = Length * width
5 5/6 = x * 1 3/4
35/6 = 7x/4
Cross multiply :
7x * 6 = 35 * 4
42x = 140
x = 140 / 42
x = 3 14/42
x = 3 1/3 feets
Hence, Length of the back of aquarium is 3 1/3 feets

From the question,
A map has a scale of 1: 1250000.
We are told that:
On a map, The cave of truth is 1.9cm away from the waterfall of dreams.
How far away are they in real life?
This is calculated as:
1 = 1250000
1.9 = x

4 2/5+k=−3 2/11
Need help
Answer:
2/11
Step-by-step explanation:
Here we have two mixed numbers. Be very careful when handeling negative mixed numbers. Don't coonfuse "-3 2/11" with "-3 + 2/11"
4 2/5 + k = -3 2/11
I add a minus into the mixed fraction on the right. Of course you don't have to write an entire new line when you do calculations on paper.
4 2/5 + k = -3 -2/11
k = - 3 - 4 - 2/5 - 2/11
k= - 7 -2/5 -2/11
Make common denominators. Both 11 and 5 is prime numbers (numbers that are only divisible by one and itself). Therefore the common denominator is 5*11=55.
k= - (7*55)/55 - (2*11)/(5/11) - (2*5)/(11*5)
k = - 385/55 - 22/55 -10/55
k = - (385 +22+10)/55
k = - 417/55
Since 417 isn't divisible by neither 11 nor 5, this fraction is in it's simplest form.
btw correct me if i am wrong
Answer:
[tex] k = - 1 \frac{12}{55} [/tex]
Step-by-step explanation:
[tex]4 \frac{2}{5} + k = 3 \frac{2}{11} \\ \frac{22}{5} + k = \frac{35}{11} \\ k = \frac{35}{11} - \frac{22}{5} \\ k = \frac{175 - 242}{55} \\ k = \frac{ - 67}{55} \\ k = - 1 \frac{12}{55} [/tex]

Step-by-step explanation:
for the first question which would be Approximate: log5 4/7 the answer would be B. –0.3477
and for the second question which would be Approximate: log1/2 5 the answer would be C.–2.3219
Step-by-step explanation: Using Properties of Logs
logb(x/y) = logbx - logby.
Furthermore
log5 (4/7)= log5 (4)- log5 (7)
Solve log 5 (4) and log 5 (7) with the base change of the logarithm
log 5 4 = log 4 / log 5
Use the calculator (DESMOS): log 5 4 =0.8613531161
log 5 7 = log 7 / log 5
log 5 7 =1.2090619551
Therefore, The answer is, log5 (4/7)= log5 (4)- log5 (7)=-0.347708839
