a survey of 800 households revealed that 400 had only a TV, 100 had only a computer, and 100 had neither a tv nor a computer. how many households have both a tv and a computer?

Answer:

Tara makes 7x =7*15 = 105 crafts and Katie made 9x = 9*15 = 135 crafts.

Step-by-step explanation:

Crafts tara and katie make resoectively are in the ratiob 7:9. Let's say 7x and 9x.

Now,

7x + 9x = 240

so, x = 240/16

so, x = 15

The values of A, B, and C are  mathematically given as

This is further explained below.

Generally, the equation for the statement is  mathematically given as

AB + C = 52

AB+ (C x 10) = 97....1

Using the substitution technique we have

AB = 52- C ....2

Subbing 2 in 1

AB+ (C x 10) = 97

Therefore

52- C +  10C = 97

9C=97-52

9C=45

C=5

In conclusion,

AB = 52- C

AB = 52- 5

AB=48

A=48/B

Hence

B=48/A

If we have a 1/3 measuring cup and a recipe calls for 12 and 2/3 cups of flour,then we would need 38 number of cups.

Given that we have a 1/3 measuring cup and a recipe calls for 12 and 2/3 cups of flour.

We are required to find the number of cups that are needed.

Fraction is the combination of two numbers,one above the division sign and other one below the division sign. The number which is above the division sign is known as numerator and the number which is below the division sign is known as denominator.

Measuring cup=1/3

Number of cups needed in recipe=12+2/3=38/3

Number of cups needed=38/3/1/3

=38 cups

Hence if we have a 1/3 measuring cup and a recipe calls for 12 and 2/3 cups of flour,then we would need 38 number of cups.

We need to mix 15 ml of 28 % of solution to get the resulting mixture as a 13 % sugar mixture.

Let the amount of 28 % sugar solution be x ml.

We are given that:

10 % sugar solution = 75 ml

Total solution = 75 ml + x ml

We need the solution to be 13 % sugar solution.

So, we get that:

28 % x + 10 % ( 75 ) = 13 % ( 75 + x )

28 x + 750 = 13 ( 75 + x )

28 x + 750 = 975 + 13 x

28 x - 13 x = 975 - 750

15 x = 225

x = 225 / 15

x = 15

Therefore, we need to mix 15 ml of 28 % of solution to get the resulting mixture as a 13 % sugar mixture.

The solution interval for x is x ∈ (-1/4 , ∞)

An inequality shows the relationship of a non-equal comparison between two numbers or mathematical expressions.

Here, we are given two inequalities

x/4 > -1 and -4x - 4 < -3

Let us take the first equation

x/4 > -1

⇒ x > 4(-1)

x > -4

Now, the second equation

-4x - 4 < -3

-4x < -3 + 4

-4x < 1

Now since we are dividing both sides by a negative number, that is 4, the sign of the inequality will be reversed,

x > 1/-4

x > -1/4

Thus, we get x > -4 and x > -1/4

This means that all values of x greater than -1/4 will satisfy.

Thus, x ∈ (-1/4 , ∞)

Answer: 15

Step-by-step explanation:

order all the numbers from least to greatest and then find the one in the middle

Answer:

1. A = {x:x is the set of natural number <= 10}

2. E = {x:x is the set of natural number <= 8}

The intervals on which the function f of x is increasing is:

(6, 0) U (2, 4) U (7, 9)

When we have the graph of a function, we can identify if it is increasing if, reading from left to right, we can see that the graph of the function goes upwards.

For the graphed function, we can see that it increases for the values:

-6 < x < 0

2 < x < 4

7 < x < 9

Writing this in interval notation, we have:

(6, 0) U (2, 4) U (7, 9)

This is the list of intervals on which the function f(x) is increasing.

complementary angles m < DFG = 48, m < JKL =  42 is value of x .

What is the opposing angle to the above example?

Complementary angles are those whose combined angle is exactly 90 degrees. 30 degrees and 60 degrees, for instance, are complimentary angles.

∠DFG and ∠JKL are complementary angles. m∠DFG = x + 5,

and m∠JKL = x − 1

When two angles are complementary then the sum of angles is 90 degrees

∠DFG and ∠JKL are complementary angles.

So m < DFG < + m < JKL = 90

Now replace the expressions and solve for x

x + 5 +x - 1 =90

2x + 4 = 90

2x = 90 - 4

2x = 86

 x = 43

Now replace x with 43 and find out each angle

m < DFG  = x + 5

m < DFG  = 43 + 5 = 48

m < DFG = 48

m < JKL = x - 1 = 43 - 1 = 42

m < DFG = 48

m < JKL =  42

Answer: 72

Step-by-step explanation: First step that I did was to subtract 12 and 4 to get 8. I then subtracted 3 and 2 to get 1. Then since 8 and 1 are in the parenthesis, I multiplied 8 and 1 to get 8. 8 to the 2nd power then comes out to 64. 64 adding the square root of 64 which is 8 then comes out to 64 plus 8 because the square root of 64 is 8. 64 plus 8 equals 72.

The square root of 58 is around 7.6

The entire number is, 7.61577310586...

Answer:

15, 16 and 17

Step-by-step explanation:

Consecutive numbers mean numbers that are separated by 1 from each other. For example 5, 6 and 7 are three consecutive numbers and 5 is the smallest

Let the smallest number be x
Then the next consecutive number is x + 1  
The next one after that is x + 2

Sum = x + x + 1 + x + 2 = x + x + x + 1 + 2 = 3x + 3

We are told that this sum is 33 more than the smallest number x

So 3x+3 = x + 33 Subtract x from both sides
3x - x + 3 = x + 33 -x
==>  2x + 3 = 33

Subtract 3 from both sides
==> 2x + 3 - 3 = 33 -3
==> 2x = 30
Divide both sides by 2

==> 2x/2 = 30/2
==> x = 15

So the smallest number is 15 and the three numbers are 15, 16 and 17

Verify by adding 15+16 +17 = 48
15 + 33 = 48 so consistent

A: The three consecutive numbers are 15, 16, 17.

Explanation:

Let x, y, z be the numbers.

x + y + z = x + 33

y = x + 1

z = x + 2

We will solve this system of equations using the substitution method.

x + x + 1 + x + 2 = x + 33

x + x + x - x = 33 - 1 - 2

2x = 30

x = 15

y = 15 + 1 = 16

z = 15 + 2 = 17

Solving for x + y + z = x + 33:

15 + 16 + 17 = 15 + 33

48 = 48

A: 15, 16, 17.

The standard deviation is a statistic that describes the degree of volatility or dispersion in a set of numerical values. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

High sample size is typically crucial in order to be able to draw generalizations from a sample, aside from avoiding bias. Since the sample size is modest, it will thus be possible to draw general conclusions about the study utilizing a larger sample, in my opinion.

The size of the sample has a significant impact on whether an experiment is legitimate. The central limit theorem states that as sample size rises, the sample mean approaches the population means value.

Because of this, generalizing from just five samples regarding a population of city dwellers won't produce a result that can be generalized.

Step-by-step explanation:

You want to know the time it takes for Juan, running 18 m/s, to overtake Mahdi, running 6 m/s, if Mahdi has a 228 meter head start.

The time to close the gap between the runners will be ...

  time = distance/speed

  time = (228 m)/(difference in speeds) = (228 m)/(18 m/s -6 m/s)

  time = (228 m)/(12 m/s) = (228/12) s = 19 s

It will take Juan 19 seconds to catch Mahdi.
