Sample mean in sample b to be less variable and more representative of  population mean than sample mean in sample a.

Standard error measures the variability of sample means around the population mean.

It decreases as sample size increases.

Using the formula for the standard error of the mean,

Calculate the standard errors for each sample,

Standard error of sample a

= s/√(n)

= 850/√(9)

= 283.33

Standard error of sample b

= s/√(n)

= 850/√(36)

= 141.67

Where s is the sample standard deviation

And n is the sample size.

The standard error of sample b is smaller than the standard error of sample a.

Sample mean in sample b is more likely to be closer to true population mean than sample mean in sample a.

Therefore, sample mean b is more surprising as larger sample size makes it more likely and accurately represents population mean.

Step-by-step explanation:

you know how functions work ?

the variable (or variables) in the findings expression is a placeholder for actual values.

when we have an actual value, we put that into the place of the variable and then simply calculate.

x = 5

therefore, the functional calculation is

y = 3×5 - 7 = 15 - 7 = 8

keep in mind the priorities of mathematical operations :

1. brackets

2. exponents

3. multiplications and divisions

4. additions and subtractions

therefore, we need to calculate "3×5" before we deal with the "- 7" part.

Answer:

D- 5hrs

Step-by-step explanation:

If the family can hike 3 miles per hour,
for 15 miles: 15/3 = 5 hours.

Every hour they cover 3 miles per hour, so to cover 15 miles, they will take 5 hours

Answer:

D. 5 hours

Step-by-step explanation:

3 miles per 1 hour so 3/1

15 miles per x hours so 15/x

3/1 = 15/x or 3 = 15/x

get x by itself so

3 divided by 3 and 15 divided by 3

x = 5 hours

Answer:

2,10,5,6

Step-by-step explanation:

What are outliers?
Outliers are numbers that are not often used and rarely used. They are least showed. The most number used is called the mode, or average. In this case, the mode is mostly 9. Since numbers like 2,10,5, and 6 are numbers that don't show often, they are outliers. Hope this helped

Answer:

2

Step-by-step explanation:

An outlier is the number that brings that mean/average way down or way up. The outlier in this case is 2 b/c it brought down the mean/average.

Answer:

< x = 120°

Step-by-step explanation:

Step 1:

According to angle sum property,

y + 50 + 70 = 180

Step 2:

x and y are linear pairs, forming a supplementary angle.

Therefore,

x + y = 180

Step 3:

Since they are both equal to 180, equate the values

y + 50 + 70 = x + y

x = 70 + 50

x = 120

Answer:

All real numbers  are solutions

Answer: HL

Step-by-step explanation: the diagram compares the two sides, or legs, and the hypotenuse.

The answer is t ≈ 16.038 years. The population of Leadville will reach one-half of the current population after approximately 16.038 years.

To find the number of years it takes for the population of Leadville to reach one-half of the current population, we need to solve the equation P(t) = 2600 * (0.956)^t for t.

The equation represents the population at time t, where P(t) is the population, 2600 is the current population, and 0.956 is the decay factor representing the 4.4% decrease per year.

Setting P(t) to half the current population (1300), we have:

1300 = 2600 * (0.956)^t

Dividing both sides by 2600, we get:

0.5 = 0.956^t

Taking the logarithm of both sides (base 0.956), we have:

log(0.5) = log(0.956^t)

Using the logarithmic property log(a^b) = b * log(a), we can rewrite the equation as:

log(0.5) = t * log(0.956)

Now, we can solve for t by dividing both sides by log(0.956):

t = log(0.5) / log(0.956)

Calculating this using a calculator, we find:

t ≈ -16.038

Since time cannot be negative in this context, we discard the negative value. Therefore, the population of Leadville will reach one-half of the current population after approximately 16.038 years.

Rounding to three decimal places, the answer is:

t ≈ 16.038 years

Answer:

y= -2x + 0

Step-by-step explanation:

to get to y you need to multiply by -2 and add 0 to that to get the final y answer

The probability that GM is next to VP is 3/7.

We are given that;

Number of employees=3

Company B= 2

Now,

We can use this formula to find the total number of ways to arrange eight people in a line, which is P(8,8):

\($$P(8,8) = \frac{8!}{(8-8)!} = \frac{8!}{0!} = \frac{8!}{1} = 8! = 40320$$\)

We can also use this formula to find the number of ways to arrange GM and VP next to each other, which is P(2,2):

\($$P(2,2) = \frac{2!}{(2-2)!} = \frac{2!}{0!} = \frac{2!}{1} = 2! = 2$$\)

We also need to consider that GM and VP can be next to each other in six different positions: (1,2), (2,3), (3,4), (4,5), (5,6), or (6,7). For each position, we have two ways to arrange GM and VP (GM-VP or VP-GM). So, we need to multiply P(2,2) by 6 and by 2 to get the total number of ways to arrange GM and VP next to each other in any position:

\($$P(2,2) \times 6 \times 2 = 24$$\)

Finally, we need to consider that for each arrangement of GM and VP next to each other, we have six other people who can be arranged in any order in the remaining six positions. The number of ways to arrange six people in six positions is P(6,6):

\($$P(6,6) = \frac{6!}{(6-6)!} = \frac{6!}{0!} = \frac{6!}{1} = 6! = 720$$\)

So, we need to multiply P(2,2) by 6 by 2 by P(6,6) to get the total number of ways to arrange eight people in a line such that GM is next to VP:

\($$P(2,2) \times 6 \times 2 \times P(6,6) = 24 \times 720 = 17280$$\)

To find P(A), we need to divide this number by the total number of ways to arrange eight people in a line:

\($$P(A) = \frac{P(2,2) \times 6 \times 2 \times P(6,6)}{P(8,8)} = \frac{17280}{40320} = \frac{3}{7}$$\)

Therefore, by probability the answer will be 3/7.

The value of quantity d  in which a = 5.7 , b = 4.7 and c is given to be 72 is 0.12.

We are given in the question that the value of a is 5.7m, b is 4.7s, c is 72 m/s and \(d=\frac{a^{3}}{cb^{2}}\)

We have to find the value of quantity d.

Putting the values of quantities a, b and c in the given formula of quantity d, we will get,

\(d=\frac{(5.7)^{3}}{(72)(4.7)^{2}}\)

First we will find the values of the cube of 5.7 and square of 4.7.

Hence,

\((5.7)^{3}=185.193\\\\(4.7)^{2}=22.09\)

Hence, the quantity d will become:-

\(d=\frac{185.193}{(72)(22.09)}\)

Given:

The two points are (-1,2) and (5,-2).

To find:

The distance between the given points.

Solution:

Distance formula:

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Using the distance formula, the distance between the given points is

\(d=\sqrt{(5-(-1))^2+(-2-2)^2}\)

\(d=\sqrt{(5+1)^2+(-4)^2}\)

\(d=\sqrt{(6)^2+16}\)

\(d=\sqrt{36+16}\)

On further simplification, we get

\(d=\sqrt{52}\)

\(d=7.2111\)

\(d\approx 7.21\)

Therefore, the the distance between the given points is about 7.21 units.

The 90% confidence interval for the difference in the population means is -2.51 to 0.31

From the question, we have the following parameters that can be used in our computation:

xˉ₁ = −17.1

s₁² = 8.4

n₁ = 22

​xˉ₂ = −16.0

s₂² = 8.7

n₂ = 24

Calculate the pooled variance using

P = (df₁ * s₁² + df₂ * s₂²)/df

Where

df₁ = 22 - 1 = 21

df₂ = 24 - 1 = 23

df = 22 + 24 - 2 = 44

So, we have

P = (21 * 8.4 + 23 * 8.7)/44

P = 8.56

Also, we have the standard error to be

SE = √(P/n₁ + P/n₂)

So, we have

SE = √(8.56/22 + 8.56/24)

SE = 0.86

The z score at 90% CI is 1.645, and the CI is calculated as

CI =  (x₁ - x₂) ± z * SE

So, we have

CI = (-17.1 + 16.0) ± 1.645 * 0.86

This gives

CI = -1.1 ± 1.41

Expand and evaluate

CI = (-2.51, 0.31)

Hence, the confidence interval is -2.51 to 0.31
