Answer:

Carlos has practiced piano for [tex]\frac{29}{20}=1\frac{9}{20}[/tex] hours.

Carlos needs to practice [tex]\frac{11}{20}[/tex] hours.

Step-by-step explanation:

We have been given that Carlos wants to practice piano 2 hours each day. He practices piano for 3/4 hour before school and 7/10 hour when he gets home.

First of all, we will find piano practiced before school and after school by adding both amounts as:

[tex]\frac{3}{4}+\frac{7}{10}[/tex]

Make a common denominator:

[tex]\frac{3*5}{4*5}+\frac{7*2}{10*2}[/tex]

[tex]\frac{15}{20}+\frac{14}{20}[/tex]

Add numerators:

[tex]\frac{15+14}{20}[/tex]

[tex]\frac{29}{20}[/tex]  

Therefore, Carlos has practiced piano for [tex]\frac{29}{20}[/tex] hours.

Now, we will subtract [tex]\frac{29}{20}[/tex] from 2 find number of hours Carlos needs to practice to reach his goal.

[tex]2-\frac{29}{20}[/tex]

[tex]\frac{2*20}{20}-\frac{29}{20}[/tex]

[tex]\frac{40}{20}-\frac{29}{20}[/tex]

[tex]\frac{40-29}{20}[/tex]

[tex]\frac{11}{20}[/tex]

Therefore, Carlos needs to practice [tex]\frac{11}{20}[/tex] hours before going to bed in order to meet his goal.

Answer: 74.5 ft

Step-by-step explanation:

The problem involves calculating a binomial probability for 12 out of 20 adults being satisfied with airlines, given a satisfaction rate of 66%. This uses the formula for Binomial Probability: P(X=k) = C(n, k) * (p^k) * ((1-p)^(n-k)).

The question involves using Binomial Probability in statistics. Here, the experiment is repeated 20 times (20 adults are selected), each trial is independent (one adult's answer doesn't affect another's), there are two possible outcomes (satisfied or unsatisfied), and the probability of success (being satisfied) is constant (66%).

To calculate the probability of exactly 12 adults being satisfied, we use the formula for Binomial Probability:

P(X=k) = C(n, k) * (p^k) * ((1-p)^(n-k))

Where:

By subbing in these values, we can calculate the desired outcome.

Answer:

The first one. 55.3 and 40. 38

Step-by-step explanation:

Subtract all of the second legs from the first legs that they go with and find the biggest number. When this is done, the first one has the biggest number.

Answer:

The biggest decrease in time is 14.92 seconds.

Step-by-step explanation:

Consider the provided table.

Consider the row 1.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.3 seconds - 40.38 seconds = 14.92 seconds

Hence, the decrease in time is 14.92 seconds

Consider the row 2.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.29 seconds - 40.402 seconds = 14.888 seconds

Hence, the decrease in time is 14.888 seconds

Consider the row 3.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.295 seconds - 40.4 seconds = 14.895 seconds

Hence, the decrease in time is 14.895 seconds

Consider the row 4.

The biggest decrease in time from the 1st leg to the 2nd leg is:

55.037 seconds - 41.2 seconds = 13.837 seconds

Hence, the decrease in time is 13.837 seconds

From the above calculation it is clear that the biggest decrease in time is 14.92 seconds.

The required number of the joy is 2758.

Given that,
Joy is thinking of a number.
She says, "My number is 74 more than 2 thousand, 6 hundred, 8 tens, and 4 ones."

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the number be x,
The number is 74 more than 2 thousand, 6 hundred, 8 tens, and 4 ones
x = 74 + 2684

Answer:

X=18

Step-by-step explanation:

Multiply the 6 and the 15= 90

Then left with 5x so then divide 90 and 5= 18

Left with X= 18

The value of x in the given equation is x = 18.

Given is an equation 5x/6 = 15, we need to find the value of x,

To solve for x, you need to isolate x on one side of the equation.

Here's how you can do it step by step:

Start with the equation: 5/6 x = 15

To isolate x, you need to get rid of the fraction on the left side. Since the fraction has a denominator of 6, you can multiply both sides of the equation by 6 to eliminate it:

(6) × (5/6 x) = (6) × 15

The 6 on the left side cancels out the denominator 6, leaving:

5x = 90

Now, to find the value of x, you need to get x by itself on one side. Since 5x means 5 times x, you can undo this by dividing both sides by 5:

5x / 5 = 90 / 5

This simplifies to:

x = 18

So, the value of x is 18.

Jorge's statement is partially correct. 0.029 can be written as a fraction but it is 29/1000, not 29/100 since it has three decimal places.

Jorge's statement that 0.029 can be written as 29/1000 is indeed correct. When you convert a decimal to a fraction, we count the number of decimal places, which determines the denominator of the fraction. In the case of 0.029, it has three decimal places, therefore, the denominator would be 1000 (the first place represents tenths, the second represents hundredths and third represents thousandths). Hence 0.029 as a fraction is written as 29/1000, not 29/100.

Step-by-step explanation:

5(3x - 2) > 3(4x - 1)

First, use the distributive property on both sides.

15x - 10 > 12x - 3

Subtract 12x from both sides.

15x - 12x - 10 > 12x - 12x - 3

3x - 10 > -3

Add 10 to both sides.

3x - 10 + 10 > - 3 + 10

3x > 7

Divide both sides by 3.

3x/3 > 7/3

x > 7/3

Answer:

Step-by-step explanation:

in the communtive property you simply just move the numbers, in associative you move the parenthesis, and in distributive you break up the numbers

To determine the football team's change in field position using a number line, one would sequentially move 5 units left for each loss of 5 yards over 3 plays, resulting in a total change of -15 yards.

To find the football team's change in field position after the 3 plays, you can use a number line to represent the yards on the field.

If we consider the team's starting point as zero on the number line, each loss of 5 yards will be represented as moving 5 units to the left (into the negative side) from that starting point. Here's how you would calculate it step by step:

Mark the starting point at zero on the number line.

Since the team lost 5 yards on the first play, move 5 units to the left and mark that new point, which represents -5 yards.

Repeat the process for the second play, moving another 5 units to the left from the -5 mark to reach -10 yards.

Finally, for the third play, move yet another 5 units to the left to end up at -15 yards.

Therefore, after 3 plays with each losing 5 yards, the team's field position has changed by -15 yards.
