Find the value of x so that the ratios are equivalent.
1:8 and 4:x
X =
Answer:
32
Step-by-step explanation:
1 : 8 = 4 : 32
So, 4 : x = 4 : 32
x = 32
The value of x from the given ratios is 32.
Given that, the ratios 1:8 and 4:x are equivalent.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Here,
1:8 =1/8
4:x =4/x
Ratios are equivalent 1/8 = 4/x
x= 4×8
x=32
Therefore, the value of x from the given ratios is 32.

Answer:
Step-by-step explanation:
Let the exponential function for the given table is,
f(x) = a(b)ˣ
Here, f(x) = Price of the item after 'x' years
a = Initial price of the item
b = Growth factor
x = Duration(years) from year 1913
By exponential regression calculator,
Exponential function represented by the table will be,
f(x) = 7.822(1.034)ˣ
Now we have to calculate the price of the item in year 2025.
Difference in time = 2025 - 1913
= 112 years
Price of the item after 112 years,
f(112) = 7.822(1.034)¹¹²
= $330.840
Tom has a collection of 13 snakes, 4 of which are purple and 5 of which are happy. He observes that
all of his happy snakes can add,
none of his purple snakes can subtract, and
all of his snakes that can't subtract also can't add.
Which of these conclusions can be drawn about Tom's snakes?
A)Purple snakes can add.
B) Purple snakes are happy.
C) Snakes that can add are purple.
D) Happy snakes are not purple.
E) Happy snakes can't subtract.
9514 1404 393
Answer:
D) Happy snakes are not purple
Step-by-step explanation:
The first statement tells us all happy snakes can add.
The second statement tells us that all purple snakes can't subtract, and the third statement tells us that purple snakes also cannot add.
Therefore, we must conclude that happy snakes are not purple.

You want to find the width, AB, of a river. You walk along the edge of the river 100 ft and mark point C. Then
you walk 22 ft further and mark point D. You turn 90° left and walk until your location, point A, and point C are
collinear. You mark point E at this location, as shown.
(a) Suppose DE = 42 ft. What can you conclude about the width of the river? Explain. Your explanation
should include the approximate width and how you got this answer.

The explicit formula for the geometric progression is f ( x ) = 3 ( 4 )ˣ⁻¹
What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the geometric progression be represented as A
Now , the value of A is
f ( x + 1 ) = 4 f ( x )
where the second term is a₂ = 12
Now , the explicit formula is given by
f ( x ) = 3 ( 4 )ˣ⁻¹
when x = 2
f ( 2 ) = 3 ( 4 )²⁻¹
f ( 2 ) = 3 ( 4 )
f ( 2 ) = 12
Hence , the GP is f ( x ) = 3 ( 4 )ˣ⁻¹

Step-by-step explanation:
the figure is a square so all four sides are equal and has 90 degree corners.
the diagonal has the value of 6 so:
6^2=s^2+s^2
36=2s^2
s^2=18 or sq rt 18 which would be 3(sq rt 2)

A farmer wishes to determine which of two brands of baby pig pellets, Kent or Moormans, produces better weight gains. Two of his sows each give birth to litters of 10 pigs on the same day, so he decides to give the baby pigs in litter A only Kent pellets, while the pigs in litter B will get only Moormans pellets. After four weeks, the average weight gain for pigs in litter A is greater than the average weight gain for pigs in litter B. The feed they get is not the only factor affecting the rate at which pigs gain weight. Genetic differences also affect weight gain. It is likely that the pigs in litter A are genetically different from the pigs in litter B since the two litters have different mothers.
What experimental design technique could the farmer use to take into account the genetic differences?
a. Placebo
b. Blocking
c. Probability sampling
d. Double blinding
e. Observational study
Answer:
Option d (Double blinding) would be the appropriate choice.
Explanation:
A double-blind research paper would be one in which although neither group members nor even the researchers understand whose been receiving a specific intervention. This methodology has been used to protect participants throughout the research findings, which are especially beneficial throughout the prevention of bias reducing the power of personality traits or perhaps the placebo impacts.Certain other preferences are not related to just the illustration in question. So the above alternative seems to be the correct one.

In a class with 28 students, there are 19 boys. What is the ratio of girls to boys? 9:19 19:28 19:9 28:9
Answer:
9:19
Step-by-step explanation:
Total number of students = 28
Number of boys = 19
Number of girls = Total number of students - Number of boys = 28-19 = 9
Therefore, ratio of girls to boys = Number of girls/Number of boys = 9/19 = 9:19
Answer: 9:19
Step-by-step explanation: The total number of students is 28.
Subtract the number of boys, 19
28 - 19 = 9 girls
Use those numbers for the ratio.
