Answer:

5 = |-5|

Step-by-step explanation:

Think of it as a number line, like in the picture below. The absolute value is how far a number is from zero (0). If 5 is 5 away from zero, then the opposite of 5 (-5) is also 5 away from zero.

Refer to the picture below for an illustration:

Answer:

Equal to.

Step-by-step explanation:

5 is the absolute value of -5. The bars you see indicate that you are trying to find the absolute value.

----------------------------------------------------------------------------------------------------------

The absolute value is the distance of that number from 0. The absolute value is always positive.

----------------------------------------------------------------------------------------------------------

|-5|= 5. If the bars were not there, then it would be $5 > -5\\$ . If the two terms were flipped, it would be $-5 < 5$ . But because the bars are there, it is resembling the absolute value.

----------------------------------------------------------------------------------------------------------

Here are a few more examples to help you understand:

|6| The absolute value of 6 is 6. It is 6 values away from 0.

|-1| The absolute value of -1 is 1. It is 1 value away from 0.

|-10| The absolute value of -10 is 10. It is 10 values away from 0.

|98| The absolute value of 98 is 98. It is 98 values away from 0.

The concern of a study by Beynnon et al. (A-4) were nine subjects with chronic anterior cruciate ligamenttears. One of the varia

Answer:

a) Standard error of the mean = 1.433 mm

b) 99% confidence interval = (12.6, 22.2)

c) The precision of the estimate = 4 816

d) The assumptions that are necessary for the validity of the conidence interval constructed include

- The sample must be a random sample extracted from the population, with each variable in the sample independent from one another.

- The sample must be a normal distribution sample or approximate a normal distribution and the best way to establish this is when the population distribution where the sample was extracted from is normal or approximately normal.

Step-by-step explanation:

a) Standard error of the mean is given as

σₓ = (σ/√n)

σ = Sample standard deviation = 4.3 mm

n = sample size = 9

σₓ = (4.3/√9) = 1.433 mm

b) Confidence Interval for the population mean is basically an interval of range of values where the true population mean can be found with a certain level of confidence.

Mathematically,

Confidence Interval = (Sample mean) ± (Margin of error)

Sample Mean = 17.4 mm

Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error of the mean)

Critical value will be obtained using the t-distribution. This is because there is no information provided for the population mean and standard deviation.

To find the critical value from the t-tables, we first find the degree of freedom and the significance level.

Degree of freedom = df = n - 1 = 9 - 1 = 8.

Significance level for 99% confidence interval

(100% - 99%)/2 = 0.5% = 0.005

t (0.005, 8) = 3.36 (from the t-tables)

Standard error of the mean = 1.433 mm

99% Confidence Interval = (Sample mean) ± [(Critical value) × (standard Error of the mean)]

CI = 17.4 ± (3.36 × 1.433)

CI = 17.4 ± 4.816

99% CI = (12.584, 22.216)

One crate orė

99% Confidence interval = (12.584, 22.216)

c) The precision of the estimate is gven as the length of the, margin of error of the confidence interval. The precision of the estimate = 4.816

d) They include

- The sample must be a random sample extracted from the population, with each variable in the sample independent from one another.

Hope this Helps!!!

Able has a younger sister and an older brother. - Able’s age can be represented by x. - Able’s sister is 4 years younger than hi

kakasveta [241]

Answer:

5 years old

Step-by-step explanation:

Able has a younger sister and an older brother.

Able’s age can be represented by x.

Able’s sister (s) is 4 years younger than him. This can be represented as:

s = x - 4 [1]

Able’s older brother (b) is twice as old as he is. This can be represented as:

b = 2x [2]

The combined age of all three siblings is 32. This can be represented as:

x + s + b = 32 [3]

If we replace [1] and [2] in [3], we get:

x + (x - 4) + 2x = 32

4x = 36

x = 9

The age of Able's younger sister is:

s = x - 4 = 9 - 4 = 5
