Answers
Using sampling concepts, it is found that the sample is given by:
C. The 150 businesses who were sent surveys.
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
In this problem, a group of 150 businesses(sample) is taken from the telephone listings(all the businesses in the listings is the population), hence option C is correct.

We can make the longest side match the given value if we multiply these numbers by 4√5
y : x : 8√5 = 1(4√5) : √3(4√5) : 2(4√5) = 4√5 : 4√15 : 8√5

Answer:
The amount of each ingredient Alicia uses to make oat biscuits are;
440 g of oat, 220 g of butter, and 110 g of syrup
Step-by-step explanation:
9. The question parameters are
The ingredients with which Alicia makes oat biscuit = Syrup, butter, and oat
The ratio of the ingredients with which Alicia makes oat biscuit = 1 : 2 : 4
The quantity of syrup Alicia has = Large amount (Plenty)
The amount of butter she has = 250 g
The amount of oat she has = 440 g
From the given ratio, we have;
The mass of oat Alicia uses is 2 times the mass of butter she uses and 4 times the mass of syrup she uses
When Alicia uses the 440 g of oat, we have;
The amount of butter she will use = 440 g/2 = 220 g
The amount of syrup she will use = 440 g/4 = 110 g
Therefore, Alicia uses the 440 g of oat, 220 g of butter, and 110 g of syrup
A floor 3.2m long and 2.8 m wide is to be covered with square shaped tiles of length 10cm. Find the coast of flooring if the coast tiles is Rs 150 per 100 tile.
Answers
Answer:
1344
Step-by-step explanation:
100cm = 1 m
Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth = 320 x 280 = 89,600m²
Area of a square = length² = 10cm² = 100cm²
Number of tiles that would be needed = area of floor / area of square
89,600cm² / 100cm² = 896
Cost of one tile = rs 150 / 100 = 1.5
Cost of 896 tiles = 1.5 x 896 = 1344

You can see that your subtracting one to get to the next number.
Now look at the fractions.
9/10, 7/10, 1/2
To figure out the change you want all the fractions to have the same denominator.

What is exponential decay?An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.
The exponential decay function:
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
Given:
An element with mass 630 grams decays by 18.8% per minute.
That means, 18.8% = 0.188
Here, we will use the exponential decay function.
Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.
Here,
A₀ = 630 grams
r = 0.188
x = 7 minutes
Substituting the values to the formula,
A₇ = 630(1-0.188)⁷
A₇ = 630(0.812)⁷
A₇ = 630(0.23275134787)
A₇ = 146.633
A₇ = 146.6 grams.
Therefore, element is remaining 146.6 grams.

Triangle CDF is similar to triangle EGF
(ACDF ~ AEGF). What is the value of x?
A. 15
B.11
C. 9
D. 6
Answers
Answer:
B.11
Step-by-step explanation:
Two triangles are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion.
From the image, CF corresponds to EF, CD corresponds to EG and DF corresponds to GF.
DF = DE + EF = 7 + 5 = 12
Since Triangle CDF is similar to triangle EGF. hence:
[tex]\frac{CF}{EF} =\frac{DF}{GF} \\\\\frac{CF}{5}=\frac{12}{4} \\\\CF=\frac{12*5}{4}\\\\CF=15[/tex]
We can see that:
CF = CG + GF (line segment addition postulate)
CF = x + 4
15 = x + 4
x = 15 - 4
x = 11

Two shops, Lidal and Oldi, sell the same brand of toilet rolls but with different package sizes. Calculate the price per 36 rolls for each shop.
Answers
Answer:
The answer is below
Step-by-step explanation:
At Lidal shop, 4 toilet rolls is sold for £2.40. Therefore the cost of each toilet roll is given as:
Cost of each roll at Lidal = £2.40 / 4 = £0.60 per roll
Cost of 36 rolls = cost for each roll * 36 rolls = £0.60 per roll * 36 rolls = £21.6
At Oldi shop, 9 toilet rolls is sold for £4.68. Therefore the cost of each toilet roll is given as:
Cost of each roll at Oldi = £4.68 / 9 = £0.52 per roll
Cost of 36 rolls = cost for each roll * 36 rolls = £0.52 per roll * 36 rolls = £18.72
The crispy rice treats have cooled, Mrs. Williams cuts them into 30 equal pieces. She gives two-fifths of the treats to her son and takes the rest to school. How many treats will Mrs. Williams take to school?
Answers
Answer:
18 pieces
Step-by-step explanation:
divide 30 by 5
you'll get 6
so one-fifth is equivalent to 6 of the pieces
multiply 6 by 2
you'll have 2 so two-fifths is equal to 12 pieces of rice crispy treats
subtract 12 from 30
30 - 12 = 18
So she took 18 pieces to school.
