false becasue 11,12,13,14,15,16,17,18,19,20,21, and 22 is bigger and 111,112,113,114,115,116,117,118,119,120,121, and 122 is smaller.

Answer:

False

Step-by-step explanation:

Standard Deviation is the square root of sum of square of the distance of observation from the mean.

[tex]Standard deviation(\sigma) = \sqrt{\frac{1}{n}\sum_{i=1}^{n}{(x_{i}-\bar{x})^{2}}[/tex]

where, [tex]\bar{x}[/tex] is mean of the distribution.

Here, First distribution is 11,12,13,14,15,16,17,18,19,20,21,22

and Second distribution is 111,112,113,114,115,116,117,118,119,120,121,122

The mean of first distribution is 16.5

and mean of second distribution is 116.5

So the standard deviation of first distribution is 3.605

and the standard deviation of second distribution is 3.605

Hence, standard deviation is same for both distribution.

Well, the fraction 3/5 is in its simplest form, however, 12/15 is not. The fraction can be further simplified.

First, find out what the largest number that can fit into both the denominator (15) and numerator (12) perfectly. This number would be 3.

Next, divide 3 by 12 (which equals 4) and 3 by 15 (which equals 5). This gives you 4/5. The simplest form of the fraction 12/15.

4/5 is larger than 3/5, therefore the answer would be that they are not equivalent.

The fractions, 3/5 and 12/15 are not equivalent because they are not of the same value and are not equal.

Recall:

Thus, given the fractions, 3/5 and 12/15,

This is why:

12/15 when reduced further will give us: 4/5 if we divide both the denominator and numerator by 3.

Thus:

Therefore, the fractions, 3/5 and 12/15 are not equivalent because they are not of the same value and are not equal.

Answer,

S = -16

Explanation,

Step 1: Simplify both sides of the equation.

13 + 11s = − 15 + 8s − 20

13 + 11s = − 15 + 8s + − 20

11s + 13 = (8s) + (− 15 + − 20) (Combine Like Terms)

11s + 13 = 8s + − 35

11s + 13 = 8s − 35

Step 2: Subtract 8s from both sides.

11s + 13 − 8s = 8s − 35 − 8s

3s + 13 = − 35

Step 3: Subtract 13 from both sides.

3s + 13 − 13 = − 35 − 13

3s = − 48

Step 4: Divide both sides by 3.

3s/3 = −48/3

s = -16

Solution-

The given statement,

the mean life of a certain type of alkaline battery is no more than 63 months.

Every hypothesis test carries two opposing statements, or hypothesis, about a population parameter. The first hypothesis is called the null hypothesis.

Null hypothesis always states that the population parameter is equal to the claimed value.

If the null hypothesis is rejected, then the alternative hypothesis is going to be claimed.

[tex]\text{Null hypothesis}=H_0:\mu =63[/tex]

[tex]\text{Alternative hypothesis}=H_1:\mu >63[/tex]

In this case, the alternative hypothesis is the claim.

The null hypothesis states that the mean life of the alkaline battery is 63 months or more. The alternative hypothesis states that the mean life of the alkaline battery is less than 63 months.

The null hypothesis, denoted as H0, is the statement that the mean life of the alkaline battery is 63 months or more. The alternative hypothesis, denoted as Ha, is the statement that the mean life of the alkaline battery is less than 63 months. The claim in this case is the alternative hypothesis Ha.

Answer: YES

Step-by-step explanation:

  8p - 2q = 14

8(1) - 2(-3) = 14

8   -    -6   = 14

 8    +   6  = 14

       14      = 14

            TRUE

(p, q) = (1, -3)

Plug in the corresponding numbers to the corresponding variable

8p - 2q = 14

8(1) - 2 (-3) = 14

Simplify. Remember to follow PEMDAS. First, multiply

8 x 1 = 8

-2 x -3 = 6

8 + 6 = 14

Finally, add

(8 + 6) = 14

14 = 14 (True)

Yes, (1, -3) is a solution for 8p - 2q = 14

To find the number of hours Mrs. Beckham can spend on a balloon ride, set up and solve an inequality using the given information.

To find the number of hours Mrs. Beckham can spend on a balloon ride, we need to set up an equation using the given information. The cost of the ride is a flat rate of $50 plus $15 per hour of flight time. Let's assume the number of hours Mrs. Beckham can spend on the balloon ride is x. So, the equation becomes 15x + 50 ≤ 85. Now, we can solve this inequality to find the maximum number of hours.

Subtracting 50 from both sides gives us 15x ≤ 35. Dividing both sides by 15, we get x ≤ 35/15 which simplifies to x ≤ 7/3. Since x represents the number of hours and it cannot be negative, the maximum number of hours Mrs. Beckham can spend on a balloon ride is 2 hours.

Step-by-step explanation:

178+99=277

you can estimate

200+100=300

or

180+100=280

depends on what your teacher is looking for

Our exact sum is 277.

Understanding Addition of Three-Digit Numbers

When it comes to adding three-digit numbers such as 178 and 99, it's essential to align the numbers by their place values before adding. This aligns ones with ones, tens with tens, and hundreds with hundreds. An estimate helps to quickly determine an approximate sum before or after performing the addition.

Example Calculation:

To add 178 and 99, place them in vertical alignment:

7 (tens) + 9 (tens) + 1 (carried over) = 17. Write down the 7, carry over 1 to the hundreds place.

1 (hundred) + 1 (carried over) = 2.
So, the sum is 277.

To estimate the sum of 178 and 99, you could round 99 up to 100 for easier calculation. The estimated sum would then be 178 + 100 = 278, which is very close to our exact sum of 277.

Answer:

the correct choice is A (the theoretical probability is 1/2).

Step-by-step explanation:

The classic definition of probability is: the probability is the ratio of the number of favorable events (m) divided by the number of possible events (n):

Tia performed an experiment where she flipped a coin 200 times. The coin landed heads up 92 times and tails up 108 times (check that 92+108 is exactly 200). Then the theoretical probability of the coin landing heads up in this experiment is

.

so maybe 6 plus 3 which equals 9. Then add 8 at the end

The solution to the operation 9 + 8 is 17. If we're interpreting the phrase 'make double' as doubling the result, then the final answer is 34.

In mathematics, the operation indicated in the question requires you to add the numbers 9 and 8. To solve it, you simply combine both numbers together. So, 9 + 8 equals 17. However, the phrase 'make double' in the question isn't very clear. If it means doubling the result, then we multiply 17 by 2 which gives us 34.

There are 10 marbles total.

You picked a marble and replaced it 50 times, so you have:

9/50 were purple

16/50 were orange

6/50 were yellow

19/50 were green

Multiply those by the number of marbles:

10*9/50 = 1 4/5 purple, round to 2

10*16/50 = 3 1/5 orange, round to 3

10*6/50 = 1 1/5 yellow, round to 1

10*19/50 = 3 4/5 green, round to 4

2+3+1+4 = 10  

So you can say that there are 2 purples, 3 oranges, 1 yellow, and 4 green marbles.

We know 15 minutes contain 15*60 = 900 seconds, the time for 85 blinks

Then the time for each blink t = 900/85

Time elapsed in seconds for 51 blinks is then 51*t = 900*51/85 = 540 seconds

As the answer wants to know the seconds, find the seconds. 15 * 60 = 900. We know he blinks 85 times in 900 seconds, so divide 900 by 85 to find the rate at which George blinks. 900 / 85 = 10.588. Multiply 10.588 by 51 to find the number of seconds for 51 blinks. 51 * 10.588 = 539.988.

Autocracy and democracy are two forms of government that differ in power distribution and decision-making.

Autocracy is a form of government where power is concentrated in the hands of a single ruler or leader. In an autocracy, all major decision-making authority rests with this ruler, who typically exercises unlimited power. Examples of autocracies include absolute monarchies and dictatorships.

Democracy is a form of government where power is vested in the people, who exercise it through elected representatives. In a democracy, citizens have the right to participate in the decision-making process through voting and other forms of political participation. Examples of democracies include the United States and many European countries.

An autocracy and a democracy differ in terms of power distribution and decision-making. In an autocracy, power is concentrated in the hands of a single ruler, while in a democracy, power is distributed among elected representatives and the people. Autocracies often lack the system of checks and balances present in democracies, which can lead to abuses of power. Democracies, on the other hand, prioritize participation and representation, allowing citizens to have a say in the government.
