Basil has five numbered cards.

Two of the numbers are hidden. 4 9 9 ? ? 8

The mode of the five numbers is 8.

The mean of the five numbers is 6

c) Work out the two hidden numbers.

Answers

Answer 1

Answer:

The two hidden numbers are 8 and 1.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is given by the sum of all its values divided by the number of values.

Mode of a data-set:

The mode of a data-set is the value that appears the most.

In this question:

4, 9, x, y, 8

Mode is 8 means that at least one of them must be 8, so i will say x is 8 and we have:

4, 9, 8, y, 8

The mean of the five numbers is 6

This means that:

[tex]\frac{4+9+8+y+8}{5} = 6[/tex]

[tex]29+y = 30[/tex]

[tex]y = 30 - 29[/tex]

[tex]y = 1[/tex]

The two hidden numbers are 8 and 1.

The mean is 24.5

To find the median just find the number in the middle of an odd set

but if it happens to be an even number add the 2 middle numbers together and divide them by 2

To find the Mean add all of the numbers and divide them by the number of sets ( in this instance its 4 )

What are important things to think about when justifying a conjecture?

Answers

Answer:

Step-by-step explanation:

First, we need to understand what a conjecture means, we can take a conjecture to mean the use of observed patterns or foundational knowledge about a certain phenomenon or thing to make a decision or make a logical conclusion about such thing.

Hence, when making Justification about a conjecture, we need to take into cognizance some potent things :

1.) There must be an observed pattern, relationship between the observation upon which a conjecture is to be made. As this pattern are key to our reasoning and decision.

2.) Also, our final conclusion or conjecture will be based on the pattern observed and not on some random thought.

Consider the quadratic expression given below.

4x^2 + 8x - 60

Factor the following expression completely.

Answers

Answer:

4(x + 5)(x - 3)

Step-by-step explanation:

Given

4x² + 8x - 60 ← factor out 4 from each term

= 4(x² + 2x - 15) ← factor the quadratic

Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)

The factors are + 5 and - 3 , since

+ 5 × - 3 = - 15 and + 5 - 3 = + 2, then

x² + 2x - 15 = (x + 5)(x - 3)

Then

4x² + 8x - 60 = 4(x + 5)(x - 3) ← in factored form

Gavin took a taxi home from the airport. The taxi fare was $7 plus an additional $0.65 per mile.
Gavin gives the driver a $3 tip when he arrives home. If Gavin paid a total of $62.65 with the tip,
what is the distance between the airport and Gavin's house?

Answers

Answer:

81

Step-by-step explanation:

$62.65-$7-$3=$52.65

Distance->52.65÷0.65=81

81 miles, he paid 7$ and 3$ for a total of 10$ not including the expense per miles, so you would subtract 10$ off of 62.65$ to get 52.65$ for how much he paid for the distance, and then divide 52.65$ by 0.65$ to get 81 miles

pls answer correctly

Answers

Answer:

We conclude that the slope of the line containing the points (0, -2) and (3, -2) is:

[tex]m = 0[/tex]

Step-by-step explanation:

Given that the line includes the points

(0, -2)(3, -2)

We need to find the slope of the line containing the points between (0, -2) and (3, -2) using the formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where m is the slope between (x₁, y₁) and (x₂, y₂)

In our case,

(x₁, y₁) = (0, -2)(x₂, y₂) = (3, -2)

now substituting (x₁, y₁) = (0, -2) and (x₂, y₂) = (3, -2) in the slope formula

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{-2-\left(-2\right)}{3-0}[/tex]

[tex]m=\frac{-2+2}{3}[/tex]

[tex]m=\frac{0}{3}[/tex]

[tex]m = 0[/tex]

Therefore, we conclude that the slope of the line containing the points (0, -2) and (3, -2) is:

[tex]m = 0[/tex]

This problem says to write the product of the sum and the difference. (x+5)(x-5). I'm not sure what my teacher is asking me to do.

Answers

Step-by-step explanation:

step 1. x + 5 and x - 5 are polynomials.

step 2. x + 5 is a sum, x - 5 is a difference.

step 3. (x + 5)(x - 5) is a product which means to multiply. So "multiply" using FOIL.

step 4. (x + 5)(x - 5) = x^2 - 5x + 5x- 25 = x^2 - 25.

3 teas and 2 coffees have a total cost of £7.80.

5 teas and 4 coffees have a total cost of £14.20.

Work out the cost of one tea and the cost of one coffee.​

Answers

Answer:

coffee is £1.80 per cup and tea is £1.40 per cup

Step by Step:

The question can be written algebraically, as:(a) 3t + 2c = 7.80(b) 5t + 4c = 14.20To work out the individual costs, we need to make one of the sets of variables equal. We can do this by multiplying the equation (a), giving (c):(a) 6t + 4c = 15.60(c) 5t + 4c = 14.20We can then subtract (c) from (a), giving:t = 1.40T can then be substituted into the initial equation (a), to work out the value of c:(3 x 1.40) +2c = 7.804.20 +2c = 7.802c = 3.60c = 1.80Finally we can check these values by substituting into (b):(5 x 1.40) + (4 x 1.80) = 7 + 7.2 = 14.20Then make sure to show your answers clearly, with units:coffee is £1.80 per cup and tea is £1.40 per cup
