the following are the ages in years of members of group 8, 11, 8,10 ,6, 7, 3x ,11, 11
if the mean age is 9years
find:
1.x
2.find the modal age
3.find the median​

Answers

Answer 1

Answer:

X = 3

Mode: 11median: 9

Step-by-step explanations

3x = 3*2 = 6

(6,7,8,8,9,10,11,11,11)/9 = 81/9 = 9

Answer 2

The value of X = 3

Mode: 11

Median: 9

What are mean and median?

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median represents the middle value of the given data when arranged in a particular order.

Mode is that number that appears most frequently in the given set of data.

We are given that  the ages in years of members of group 8, 11, 8,10 ,6, 7, 3x ,11, 11 if the mean age is 9 years

3x = 3(2 )= 6

Mean = (6,7,8,8,9,10,11,11,11)/9

= 81/9

= 9

Does x=5 satisfy the equation 3x + 2 +5x= 95 explain

Answers

Answer:

No

Step-by-step explanation:

3x + 2 +5x

if x=5

3(5)+2+5(5)

=15+2+25

=42 which is not equal to 95

No, it doesn't satisfy the equation

Step-by-step explanation:

3x + 2 +5x = 95

Now putting the value of x

3×5 + 2 + 5×5 = 95

15 + 2 + 25 = 95

42 ≠ 95

Hence, x = 5 doesn't satisfy the equation 3x + 2 +5x= 95

The positive difference in the number of termites and the number of ants in the fourth month will be 189. Option B is correct.

What is the application of subtraction?

In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

It is given that, the number of termites in a nest in any given month can be represented by the function [tex]\rm f(t) = 4(3)^t[/tex].

For the fourth month,

f(4) = 4(3)⁴

f(4) = 324

From the table, it is observed that the number of ants in four months is 513.

The positive difference in the number of termites and the number of ants in the fourth month is found as,

=513-324

=189

Thus, the positive difference in the number of termites and the number of ants in the fourth will be 189. Option B is correct.

Using x = 0 you would have:

to know the least number of packs of hot dogs and buns he needs to buy so that he does not
have any left over.
) Complete the table.

Answers

Answer:

10, 20,30, 40, 50

Step-by-step explanation:

You times them all by 10 for example: 1x10=10 2x10=20 3x10= 30 4x10=40 and 5x10=50.

If we buy four packs of hot dogs and five packs of buns then we don't have any left over.

What is Least common multiple?

The abbreviation LCM stands for "Least Common Multiple." The smallest multiple that two or more numbers share is known as the least common multiple.

For example: Take two integers, 2 and 3.

Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20….

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 ….

Therefore, 6 is the least common multiple of 2 and 3.

Given:

Packs          1       2     3      4       5

Hot Dogs   10     20   30   40    50

Bun             8      16     24   32    40

Also, LCM(10, 8)

10= 2 x 5

8= 2 x 2 x 2

So, LCM(10, 8)= 2 x 2 x 2 x 5 = 40

Hence, If we buy four packs of hot dogs and five packs of buns then we don't have any left over.

A science class has 5 girls and 3 boys in the seventh grade and 4 girls and 4 boys in the eighth grade. The teacher randomly selects a seventh grader and an
eighth grader from the class for a competition. What is the probability that the students she selects are both boys?
Write your answer as a fraction in simplest form.

Answers

Answer:

To find the probability of picking two boys, we need to first know how many different ways she can pick the 7th and 8th grader.

There are 12 7th-graders and 8 8th-graders. So the total number of ways she can pick is:

12

×

8

=

96

To get two boys picked, there are 5 boys in the 7th-grade class and 4 in the 8th-grade class, so there are:

=

Graph the linear equation 5x-4y < 20

Answers

using a graphing calculator:

Answer: (See attached image file)

Step-by-step explanation:

Start by plotting given key features

Based on the problem, we know that the x-intercept is (0,4) We find this by plugging in 0 for y, and solving for x  (5x = 20)(x = 20/5 = 4)        (4, 0)  

We can also easily solve for the y-intercept, which is (0,-5)We find this by plugging in 0 for x, and solving for y(-4y = 20)(y = -5)      (0, -5)  

Since we know that the equation is linear, seeing as the highest exponent is 1, we know that these two points have to be connected by a single, straight line.

Finally, we shade in the side to the LEFT of the line. This is because the equation asks for LESS THAN. If however the question had been 5x-4y>20, we would shade in the region to the right.

Answers

Answer:

y = 3x - 6

Step-by-step explanation:

(1, -3) (7, 15)

Step 1. Find the slope

Slope = 3

Step 2. Create the equation of the slope then use a point and plug it in as terms of x and y with a y-intercept at the end

y = 3x + b

(15) = 3(7) + b

15 = 21 + b

15 - 21 = b

b = -6

Thus, the equation of the line is y = 3x - 6
