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.

What is the equation of the line that passes through the point (−7,−1) and has a slope of 11?

Answers

Answer:

          y = 11x + 76

Step-by-step explanation:

The equation of a line with a slope of "a" and containing a given point (x₀, y₀) is:

y - y₀ = a(x - x₀)

a = 11,  x₀ = -7,  y₀ = -1

So:

y - (-1) = 11(x - (-7))  

y = 11x + 77 - 1

y = 11x + 76

A bag contains 8 red marbles, 12 blue marbles, and 17 green marbles. If one marble is randomly selected
from the bag, what is the probability that the marble is red or green?
for

Answers

Answer:

There are 37 marbles.

Probability = (# favorable outcomes) / (# total outcomes)

P (r or g) = 25/37

3) 25/37

Step-by-step explanation:

The probability of red or green marbles is 0.676

How to determine the probability?

The given parameters are:

8 red marbles, 12 blue marbles, and 17 green marbles

The number of red or green marbles is:

Red or Green = 8 + 17

Evaluate

Red or Green = 25

The probability of red or green marbles is:

P = 25/(8 + 12 + 17)

Evaluate

P = 0.676

Hence, the probability of red or green marbles is 0.676

An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.
Find the term of the sequence that has value -93. please answer asap.​

Answers

Answer:

50th term

Step-by-step explanation:

Second term, a + d = 3

Tenth term, a + 9d = -13

a + d = 3 (1)

a + 9d = -13 (2)

Subtract (1) from (2) to eliminate a

9d - d = -13 - 3

8d = -16

d = -16/8

d = -2

Substitute d = -2 into (1)

a + d = 3 (1)

a + (-2) = 3

a - 2 = 3

a = 3 + 2

a = 5

Find the term of the sequence that has value -93.

nth term = a + (n -1)d

-93 = 5 + (n - 1) -2

-93 = 5 + (-2n + 2)

-93 = 5 - 2n + 2

-93 = -2n + 7

-93 - 7 = -2n

-100 = -2n

n = -100/-2

n = 50

50th term = -93

whats a reasonable estimate for 529 divided by 23 ( explain your anwser )

Answers

Step-by-step explanation:

First you divide 529 and 23. You can divide 5w9 by 23 in a fraction like this 529/23 on to Desmos scientific calculator or just 529÷23 on a calculator. If it is a decimal, round it up if the tenth, hundredth, or thousandth is 5, 6, 7, 8, 9 or round down if the number is 4, 3, 2, and 1. The answer to 529÷23 is 23. And if you estimate it, it'll be 20. The next part may be a bit confusing but if you estimate 23, you'll get 25.

Then you estimate 529 and 23, you'll get 530 and 20. And if you divide them, you'll get 26.5. And if you estimate that, you'll get 27. So that means is 2 or 7 off from the estimated from the equation 529÷23. So that means the reasonable answer is probably 25 or 27.

Tell me if I'm right or not, and I'm sorry if I'm wrong because I don't know what answer I explained in the two paragraphs I wrote is right or wrong.

Step-by-step explanation:

In the divisor (the second fraction) we flip the numerator and the denominator. This is known as the reciprocal and basically it means the reverse of the fraction. When we find the reciprocal, we also have to change the division sign to a multiplication sign.

Once you've flipped the second fraction and changed the symbol from divide to multiply, we can multiply the numerators together and the denominators together and we have our solution:

Answers

Answer:

24m²

Step-by-step explanation:

..,.................

Area = 5*4+2*1+2*1

Area = 20+2+2

Area = 24m²

Answer:

24 m^2

Step-by-step explanation:

We need to study the structure well

We can find the magnitude of the big rectangle. We will need to find the total length and total breadth of the big rectangle

Then we remove the area of the four squared cut out from the big rectangle.

Total length of the rectangle is 5+1+1=7m

Then the length of the breath of the rectangle is 2+1+1=4m

So area of rectangle is given as length × breadth

Area= l×b

Area=7×4=28m²

Area of the big rectangle is 28m²

Then the squared is made of dimension 1m by 1m

Area of a square is s²

Then, a=1m

Area of the square= 1²=1m²

There are four squared side

Then, the total area of the four squared is 4×1=4m²

Then the required area is

Area=Total area - area of four squared side

Area=28m²-4m²

Area =24m²

Area of the figure is 24m²

The correct option is A.
