What is the length of the hypotenuse in 2 decimal places

For all samples of 5, there is a 0.05 probability that the sample mean would be higher than 22 pounds.

The assortment of bags weighs 19.7 pounds on average.

3.1 pounds is the standard deviation.

The sampling distribution theorem and the normal probability density function were both utilized.

The z-score formula is used to address problems involving samples with regularly distributed data.

Mean standard deviation, the z-score of a measure X is given by:

z = (x - μ) ÷ σ

The Z-score computes the number of standard deviations. The metric used is the average.

After calculating the Z-score, we look at the p-value associated with it in the z-score table.

This p-value represents the probability that the measure's value is smaller than X, or the percentage of X.

By taking away 1, we can determine the chance that the measure surpasses X.

If n is at least 30, the Central Limitation Theorem can also be applied to variables that are skewed.

No of the sample size, the sample mean will always be the same.

However, the standard error will change.

P(a > 22) denotes the likelihood that the sample means will be greater than 22.

The likelihood that they give it a chance will weigh more than 22 pounds is around 0.05 for all sampling of size 5.

The ratio of c and 10 is c:10.

According to the question,

We have the following information:

We have one variable and one number which are c and 10 respectively.

Now, we already know that ratio can be simply understood as division. So, to find the ratio of c and 10 we will divide c by 10. We also know that a variable can not be divided by a number.

(For example, x can not be divided by 20.)

So, we will replace the sign of division by that of the ratio.

A. The correlation coefficient is of 0.303.

B. There are six positive and four negative.

C. The point with the largest residual is (6,2).

By choosing the points (x,y) from the scatter plot and entering them into a calculator, the correlation coefficient can be calculated.

A) The coordinates of these points are:

(1,2), (1,3), (2,4), (3,4), (3,5), (4,3), (4,5), (5,5), (5,6), (6,2).

The temperature of the hottest day in Oklahoma in Celsius to the nearest tenth of a degree is 48.89 degrees.

The process of converting a temperature value from one unit to another is known as temperature conversion. On scales like Kelvin, Celsius, Fahrenheit, etc., we measure temperature. The freezing point and boiling point of water, respectively, are 273.15K and 373.15K on the Kelvin scale. The freezing point and boiling point of water, respectively, are 32°F and 212°F on the Fahrenheit scale. The freezing point and boiling point of water, respectively, are 0°C and 100°C on the Celsius scale.

Given, The hottest day recorded in Oklahoma was 120° Fahrenheit

F=(9/5)C+32

120=(9/5)C+32

(9/5)C=88

C=48.89

Therefore, the temperature of the hottest day in Oklahoma in Celsius to the nearest tenth of a degree is 48.89 degrees.

Step-by-step explanation:

∠CBA ≌ ∠DBA are equal by SAS

Answer:

Step-by-step explanation:

We start by developing an equation for Line 1, and then use that to find the equation for Line 2.  We'll use the form of an equation for a straight line:

 y = mx + b,

where m is the slope and b the y-intercept (the value of y when x=0).

Line 1

Determine the slope, m, by calculating the "Rise/Run" between the two points (-3,-7) and (5,3).

Line up the two points from left to right (based on x) and then calculate:

  Rise:  (3 - (-7)) = 10

   Run:  (5 -(-3) = 8

The slope, m, is Rise/Run or (10/8)

The equation becomes y = (5/4)x + b

We could calculate b, the y-intercept, by entering one of the two given points and solving for b, but the only thing we need from this line is it's slope, m.  Slope is (5/4), which we'll use in the next step:  Line 2.

[Note:  Out of curiosity, here is the calculation for b:  Use point (5,3) in y = (5/4)x + b and solve for b.   3 = (5/4)*5 + b.  3 = (25/4) + b  b = -13/4.  This means that Line 1 is y = (5/4)x -(13/4)]

Line 2

The slope of a line perpendicular to the first is the "negative inverse" of the first line.  In this case, line 1's slope of (13/8) would become a slope of -(8/13) for line 2.

    Line 2:  y = -(8/13)x + b

We'll calculate b for this line by enetering the single point provided,  (-4,-2), and solving for b:

          y = -(8/13)x + b

        -2 = -(8/13)*(-4) + b

          -2 = (32/13) + b

          -2 - (32/13) =  b

b = -(26/13) - (32/13)

b = -(58/13)

The new line perpendicular to Line 1 and passing through (-4,-2) is:

          y = -(8/13)x -(58/13)

The probability of randomly drawing a value greater than 3.0 from a z-distribution is 0.0013

The Z-score, commonly referred to as the standard score, expresses how far away from the mean an object is.

An element that is below the mean is indicated by a z-score that is less than 0.

An element bigger than the mean is indicated by a z-score greater than 0.

An element that is equal to the mean is represented by a z-score of 0.

P(Z > a) = 1-P(Z<a)

Let's say we want to know, for instance, the likelihood that a z-score will be higher than 3.00.

We learn from the table, that

P(Z < 3.00) = 0.9987.

Therefore,

P(Z > 3.00) = 1 - P(Z < 3.00)

= 1 - 0.9987

= 0.0013.

Therefore, the probability of randomly drawing a value greater than 3.0 from a z-distribution is 0.0013

The equation that could solve how many hours it will take for the second car to catch up to the first car is 55t = 120 + 40t.

An algebraic expression is the combination of numbers and variables in expressing and solving a particular mathematical question. An equation is the equality of expressions.

If the first car is going 40 mi/h, and has a 120 mile head start, then the distance it covers at time = t is,

d1 = 120 + 40t

If the second car is going 55 mi/h, you want to know the amount of time it will catch the first car, then, their distance must be equal.

d2 = 55t

d1 = d2

120 + 40t = 55t

What is factor of the polynomial?

A polynomial with coefficients in a certain field or in integers is expressed as the product of irreducible factors with coefficients in the same domain in mathematics and computer algebra, which is known as polynomial factorization.

A polynomial can be factored by expressing it as the product of two or more components; this is somewhat the opposite of multiplying.

From the given graph we can see that, graph crosses x - axis at points

x = 1 and x = 8.

That means x = 1, 8 are the zero of the polynomial.

Since, if x = a is a zero of the polynomial, then (x - a) is the factor of the polynomial.

As x = 1, 8 are zero of the polynomial so (x - 1) and (x - 8) are the factors of the polynomial.

Hence, from the given options (x - 1) is factor of the polynomial.

The standard error with "mean of 7 for some characteristic of interest and a standard deviation of 9.6 and a sample is drawn from this population of size 64" is 1.2.

Standard deviation of the theoretical distribution of a large population of such estimates is equal to the standard error, which is a measure of an estimate's statistical accuracy. The population mean's likelihood to differ from a sample mean is indicated by the standard error of the mean, or simply standard error. It reveals how much the sample mean would change if a study were to be repeated with fresh samples drawn from a single population.

Here,

Sample size=64

Standard deviation= 9.6

Error=Standard deviation/Sample size

=σ/√n

=9.6/√64
