Answer:

  3/7

Step-by-step explanation:

The fraction is ...

  [tex]24\text{ g to }56\text{ g}=\dfrac{24\text{ g}}{56\text{ g}}=\dfrac{3}{7}\cdot\dfrac{8\text{ g}}{8\text{ g}}=\boxed{\dfrac{3}{7}}[/tex]

Answer:

3 / 7

Step-by-step explanation:

Fraction :-

24 g to 56 g

= 24 g / 56 g

= 3/7 + 8 g / 8 g

= 3/7

Answer:

34

Step-by-step explanation:

The sum of the angles of a triangle is 180

26x+6 + 21x-1 +11x+1 = 180

Combine like terms

58x +6 = 180

Subtract 6 from each side

58x = 180-6

58x = 174

Divide by 58

58x/58 =174/58

x=3

We want <C

<C = 11x+1 = 11*3+1 = 33+1 = 34

Answer:

66.1

Step-by-step explanation

To round the decimal number to its nearest tenth, look at the hundredth number. If that number is greater than 5, add 1 to the tenth value. If it is less than 5, leave the tenth place value as it is, and remove all the numbers present after the tenth’s place.

Step-by-step explanation:

when dividing subtract the exponents

Answer:

If A > B (A is greater than B), A will be on the right side of B, and B will be on the left side of A on a number line.

Step-by-step explanation:

This is because as you keep on going right on a number line, the numbers keep getting greater. Same idea vise versa (left side gets lesser). Therefore, if A is greater than B, it will be to the right of B on a number line. Look below for an example:

Answer:

Step-by-step explanation:

Write the power of ten in standard form and do the multiplication.

  2.09 × 10^5 = 2.09 × 100,000 = 209,000

  9.4387 × 10^4 = 9.4387 × 10,000 = 94,387

  1.3 × 10^-3 = 1.3 × 0.001 = 0.0013

✍ Having as t₃ =10 and t₁₀ = -4.  We have to find the common ratio.

❑  If, in front of the sequence from 3 to 10, there are 7 numbers, that is, 7 terms, we have to find a pattern, what I used was this one.

[tex]\large {\text {$ \sf 7 \longrightarrow Number \: Terms $}}[/tex]

[tex]\large {\text {$ \sf x \longrightarrow rasion $}}[/tex]

          We see that in the calculation, the only number that fits is -2.

➤ Because if we stop to think about it, we have -2 of common ratio among these 7 terms is -14, so 10-14 = -4

So the hypothesis is correct!

➜ Being right as -2 and resuming the terms of 10, we have:

[tex]\huge {\boxed {\blue {\sf t_{10}, t_{11}, {\bf t_{12}} = \{ -4 , -6 , \bf -8 \} } }}[/tex]

So t₁₂ is equal to -8.

Answer:

[tex]a_n = 9 - 2(n-1)[/tex]

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms is always the same, and is called common difference.

The nth term is given by the following equation:

[tex]a_n = a_1 + (n-1)d[/tex]

In which [tex]a_1[/tex] is the first term and d is the common difference.

First term is 9 common difference is -2

This means that [tex]a_1 = 9, d = -2[/tex]

So, the nth term is given by:

[tex]a_n = a_1 + (n-1)d[/tex]

[tex]a_n = 9 + (n-1)(-2)[/tex]

[tex]a_n = 9 - 2(n-1)[/tex]

Answer:

It takes an apprentice four times as long as the experienced plumber to replace the pipes under an old house. It takes them 14 hours when they work together.

Step-by-step explanation:

5/(4x) = 1/14

x = 35/2

The plumber takes x = 35/2 hours to replace the pipes alone.

The apprentice takes 4x = 70 hours to replace the pipes alone.

Answer:

Step 1: True

1. Approximately 2000 families are in the sample.

2. False.

3. 31.2 hours.

4. False.

Step-by-step explanation:

The 55th percentile is greater than or equal to 30 hours.

The median is of 31.2 hours, which means that the 50th percentile is of 31.2 hours. The 55th percentile is above the 50th percentile, and thus, the 55th percentile is greater than 31.2 hours, and thus, also greater than 30 hours, and the statement is true.

1: Approximately how many families are in the sample?

Twenty-four of the families in the sample turned on the television for 20 hours or less for the week. The 12th percentile of the data is 20 hours, and thus 24 is 12% of the sample size n. So

[tex]0.12n = 24[/tex]

[tex]n = \frac{24}{0.12}[/tex]

[tex]n = 2000[/tex]

Approximately 2000 families are in the sample.

2: Based on the given information, determine if the following statement is true or false. Approximately 200 families turned on their televisions for less than 35 hours.

The median, that is, the 50th percentile, is of 31.2 hours.

Thus, 35 hours is above the 50th percentile, which means that more than 1000 families(considerably more than 200) will have turned on their TVs for less than 35 hours, and this statement is false.

3: What is the value of the 50th percentile?

The median, which is of 31.2 hours.

4: Based on the given information, determine if the following statement is true or false.The first quartile is greater than or equal to 20 hours.

20 hours is the 12th percentile, which means that the first percentile is less than 20 hours, and this statement is false.

Answer:

0.9375 ths of a cup of milk

Answer:

75%

88.89%

Step-by-step explanation:

Given :

Mean = 70

Standard deviation = 12

Since the data is said to be extremely skewed, we apply Chebyshev's theorem rather than the empirical rule :

The minimum proportion of observation between 46 and 94

Chebyshev's theorem :

1 - 1 / k²

k = number of standard deviations from the mean

k = (94 - 70) / 12 = 24 / 12 = 2

Hence, we have ;

1 - 1/2²

1 - 1/4

1 - 0.25 = 0.75

Hence, The minimum proportion of observation between 46 and 94 is 75%

Between 36 and 106 :

k = (106 - 70) / 12 ;

k = 36/12 = 3

Hence,

1 - 1/3² = 1 - 1/9 = 8/9 = 0.8888 = 88.89%

The minimum proportion of observation between 34 and 106 is 88.89%

Answer:

45

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

Given the mean of 8 numbers is 41 , then

[tex]\frac{sum}{8}[/tex] = 41 ( multiply both sides by 8 )

sum of 8 numbers = 328

Given the mean of 2 numbers is 29 , then

[tex]\frac{sum}{2}[/tex] = 29 ( multiply both sides by 2 )

sum of 2 numbers = 58

The sum of the remaining 6 numbers = 328 - 58 = 270 , so

mean = [tex]\frac{270}{6}[/tex] = 45

The mean of the other 6 numbers = 45
