Answer:

Answer is option C.

Step-by-step explanation:

This is because it does not take into account "random selection" (probability). Thus the mode of selection is biased. The mere fact that a teacher selects his favourite student means the experiment is biased.

p < 8

Answer:

The answer is A on Edge

Step-by-step explanation:

Answer:

A proportional relationship is one in which two quantities vary directly with each other.We say the variable varies directly .If y=k.x   then as x increases y  also increases.Here k is called the constant of proportionality.

The given equation y = 4.2x is of the form y=k.x where k= 4.2 as x increases y value will also increase. The relation is called a proportional relationship.

Answer:

j < 5

Step-by-step explanation:

=> 10 > j+5

Subtracting both sides by 5, we get

=> 10-5 > j

=> 5 > j

OR

=> j < 5

Answer:

(2B/m) - k = r

Step-by-step explanation:

B =1/2m(r + k)

Multiply each side by 2

2B =m(r + k)

Divide each side by m

2B/m = m/m (r+k)

2B/m =(r+k)

Subtract k from each side

(2B/m) - k = r+k-k

(2B/m) - k = r

Answer:

Here is the answer.

Step-by-step explanation:

b) students are the frequency. so we need to add all the frequency.

5 + 4  + 7 + 10 + 4=30 students

c) here we need to use the summation.

total/ frequency= mean

6*5=30

7*4=28

8*7=56

9*10=90

10*4=40

we need to add them all= 244

total frequency= 30

mean = 244/30= 8.133333333...≈ 8 (this is a rounded of value as  in 0.13, 3 goes on repeating.

Answer:

The height will be same in 6 years time

Step-by-step explanation:

Since we do not know the years it would take, we can call this x

Kindly note that 12 inches is 1 feet, so 5 ft would be 60 inches and 10 feet will be 120 inches

Now, the height of tree A after x years would be;

60 + 18x

For tree B, height would be 120 + 8x

Now, we were made to know that they have equal height at the xth year.

Thus;

60 + 18x = 120 + 8x

10x = 120-60

10x = 60

x = 60/10 = 6

Solution,

Let the price of car be X.

Rate(R)=5%

Here,

Commission % of price of car=32500

or,5% of X=32500

or,5/100*X=32500

or,X=32500*20

X=Rs 650000

Answer: a) similar, AA similarity, ΔKQR

Step-by-step explanation:

Given: QR || ML therefore,

∠KLM ≡ ∠KQR by Alternate Interior Angles Theorem

∠KML ≡ ∠KRQ by Alternate Interior Angles Theorem

also, ∠RKQ ≡ ∠MKL by Vertical Angles Theorem

Since the angles are congruent then

ΔKLM ≅ ΔKQR by Angle-Angle Similarity Theorem

Answer:

g(x) = [tex]12.(\frac{3}{4})^x[/tex]

Step-by-step explanation:

Exponential function g has been represented by the table attached,

Equation of the exponential function is,

g(x) = [tex]a.(b)^x[/tex]

Now we substitute the values of x and g(x) from the table,

For a point (0, 12),

12 = [tex]a(b)^0[/tex]

a = 12

For another point (1, 9),

9 = [tex]a.(b)^1[/tex]

9 = a × b

9 = 12 × b

b = [tex]\frac{9}{12}[/tex]

b = [tex]\frac{3}{4}[/tex]

Therefore, equation of the exponential function will be,

g(x) = [tex]12.(\frac{3}{4})^x[/tex]

Answer:

£160

Step-by-step explanation:

£160 times 0.6 equals  £96

since  £96 is 60% of the original price since 40% was taken off

The price of the bicycle before decrease is obtained as  £160.

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100. And to convert a fraction or a decimal into percentage, they are multiplied by 100.

The new price of the bicycle is  £96.

And, the percent of decrease is 40%.

Suppose the original price be x.

Then, the following equation can be written for the given case as,

x - 40% × x = 96

⇒ x - 40/100x = 96

⇒ 60/100x = 96

⇒ x = 160

Hence, the original price of the bicycle is given as £160.

Answer:

OC. $57.28

Step-by-step explanation:

It depends on how much she sells them for.

Let's say Anne sells them for $x.

Then her profit is:

8x-(8*7.16)

=8x-57.28

To make a minimum to at least make even is $57.28 and sell for $7.16 a piece.

Anne makes a profit of $57.28 on the sale of these 8 canvases. which is the correct answer would be option (C).

The profit is equal to the difference between the selling price and the original cost price.

Anne purchases art supplies for her business from a wholesaler. She spends $7.16 on eight 16 by 20-inch canvases.

To calculate the profit that Anne makes on the sale of these 8 canvases, you need to know the price at which she sells them and the cost of buying them from the wholesaler. If the cost of each canvas is $7.16 and she buys 8 of them, the total cost of the canvases is :

⇒ 8 × $7.16

Apply the multiplication operation and we get

⇒ $57.28.

Therefore, she makes a profit of $57.28 on the sale of these 8 canvases.

Hence, the correct answer would be an option (C).

Answer:

Step 2.

Step-by-step explanation:

When you have a coefficient on a side of the equation that you need to get rid of, you must divide by the number. For example, in the problem:

3(x+8)² = 75

Here, you need to divide both sides by '3' instead of multiplying, which was done instead. Then you get:

(x+8)² = 25.

Therefore, his mistake was made at Step 2.

Answer: +6

Explanation: The equation x² - 36 = 0 is called a quadratic equation because he have a squared term as our highest power.

Our first step in this problem is to get the x²

term by itself by adding 36 to both sides.

That gives us x² = 36.

Next we must get the x by itself and in order to do

that we do the opposite of what is happening to x.

Since x is being squared, the opposite

of squaring is square rooting.

So to get x by itself, we square

root both sides of the equation.

On the left the square root of x² is x and on

the right, remember the following rule.

When square rooting both sides of

an equation, always use plus or minus.

So the answer to this problem would be +6.

So our solution to this equation is +6.
