What is a standard deviation?

The standard deviation is a measurement of how much a group of values vary or are dispersed. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

Here, we have

Given: When Julia goes bowling, her scores are normally distributed with a mean of 200 and a standard deviation of 14.

we have to find the percentage of the games that Julia bowls she scores between 158 and 242.

Mean = 200

she scores between 158 and 242

(158 - 200)/14  = - 3

(242 - 200)/14  =   3

Hence her score lies within - 3SD to + 3SD

As per the empirical rule  

100 % of data lies within - 3SD to + 3SD

Hence, she will score 100 % between 158 and 242.

The value of the given expression is obtained using the property of composite function as g(f(2)) = 5.

For two functions f(x) and g(x), a composite function is defined as f(g(x)) or g(f(x)). The characteristics of this function can be described as,

The inverse of a composite function is equivalent to the composition of the inverse of both functions.

The composition of two one to one functions is always one to one.

The given table shows the values of two functions f(x) and g(x).

The given expression is equivalent to the value of g(f(x)) at x = 2.

Now, g(f(2)) can be obtained as follows,

The tip of her shadow moving when she is 35 feet from the base of the pole is 8.77 feet.

Let H = the height of the pole.

h = the height of the woman.

x = the length of the woman's shadow.

s = the distance from the pole to the woman.

By similar triangles,  H/h = (s + x)/x  or  Hx = h(s + x).

Differentiating, H dx/dt = h(ds/dt + dx/dt)

⇒ 17 dx/dt = 6(6 + dx/dt)

                  = 36 + 6 dx/dt

                  = 13 dx/dt

                  = 36

⇒ dx/dt = 36/13 ft/sec = 2.77 ft/sec for how fast her shadow is lengthening.

Step-by-step explanation:

what grade are you in bro?

The proportion of the students for the given condition is 0.0228 and the 71 percentile of the normal distribution of the test score is equal to 23.106.

As given in the question,

Mean of the normal distribution 'μ' = 22 points

Standard deviation of the normal distribution 'σ' = 2 points

Z score is calculated using :

z = (x - μ)/σ

Here, x represents the raw score

a. Condition: Students score at least 26 points

x > 26

⇒ (x - μ) / σ > ( 26 - 22 ) / 2

⇒ (x - μ) / σ > 4 /2

⇒ (x - μ) / σ > 2

⇒ z > 2

Proportion of the students scored z > 2

P(z > 2) = 1 - P(z < 2)

             = 1 -  0.9772

             = 0.0228

b. 71 percentile has a z score of 0.553

0.553 = (x - 22)/2

⇒x - 22 = 1.106

⇒ x = 23.106

Therefore, the proportion of the students scored at least 26 points are 0.0228 and 71 percentile of the normal distribution of the test score is equal to 23.106.

--x(x + 4)(x + 1)(x-9) , -3x(x+4)(2x + 2)(x-9) and  -3x(x + 4)(x + 1)(x − 9)²

Here given polynomial function,

a. 3x(x-4)(x - 1)(x + 9)

if x = 0

then the function becomes 0

but -4 , -9 , -1 does not satisfy.

Therefore the function does not have four zeroes

b. --x(x + 4)(x + 1)(x-9)

Here the function will have four zeroes,

x = 0

(x + 4 ) = 0 when x = -4

(x + 1 ) = 0 when x = -1

(x - 9) = 0 when x = 9

Therefore the function has four zeroes.

c. -3x(x+4)(2x + 2)(x-9)

Here the function will have four zeroes,

x = 0

(x + 4 ) = 0 when x = -4

(2x + 2 ) = 0 when x = -1

(x - 9) = 0 when x = 9

d. 3x(x+4)(x-1)(x-9)

Here the function will have four zeroes,

x = 0

(x + 4 ) = 0 when x = -4

(x - 1 ) = 0 when x = 1

(x - 9) = 0 when x = 9

Here x = -1 does not satisfy, So the function does not have four zeroes.

e. -3x(x + 4)(x + 1)(x − 9)²

Here the function will have four zeroes,

x = 0

(x + 4 ) = 0 when x = -4

(x - 1 ) = 0 when x = 1

(x - 9)² = 0 when x = 9

Therefore the function has four zeroes.

Therefore the polynomial functions with four zeros at -4,-1,0, and 9 are as follows: —x(x + 4)(x + 1)(x-9), -3x(x+4)(2x + 2)(x-9) and

Answer:

100

Step-by-step explanation:

70 % is .7 in decimal

   .7 * x = 70    divide both sides by .7

     x = 100

Step-by-step explanation:

you mean

70% of x = 70

right ?

you know that the "whole" is represented by 100% ?

this is easy here, but in general, when in doubt, find either 100%, calculate 1% as 100%/100 and find the desired %, or you find 1% directly and calculate the needed % (incl. 100%) out of this.

so, we know, 70% = 70

that means

1% = 70%/70 = 70/70 = 1

and then

100% = 1%×100 = 1×100 = 100

so,

70% of 100 = 70

now you see, why I said this is easy in this case here. because % and the absolute numbers have the same units. so, this goes 1:1.

The option that has the statement that best describes the the meaning of the y-intercept of the regression line is the option;

When the attendance is 0, the predicted number of wins is 15.2

A regression is a representation of a linear relationship between an input and an output variable. It is a model of the relationship between the variables presented in a linear form.

The regression equation is; [tex]\hat {y}[/tex] = 4.9·x + 15.2

Where:

x = The game attendance (in thousands)

[tex]\hat{y}[/tex] = The predicted number of times the team wins

The y-intercept represents the point at which the graph of the regression line equation intersects or touches the y-axis, which is the point where the x-value is 0, therefore, at the y-intercept, we get;

x = 0, [tex]\hat{y}[/tex]  = 4.9 × 0 + 15.2 = 15.2

At the y-intercept, [tex]\hat {y}[/tex] (the predicted number of wins) = 15.2

The description of the y-intercept is therefore, that when there is 0 attendance, the predicted number of wins of a base ball team is 15.2

The statement that describes Jaden's error is; Jaiden should have added

zeros to each of the shorter decimals to get 2.615, 2.650, 2.700, and 2.623, then he should have compared them using place values.

What is error?

Actions that are inaccurate or incorrect are considered errors. An error is the same as a mistake in some contexts. The word 'errare,' which means 'to stray,' is where the etymology originates from. In statistics, the term "error" describes the discrepancy between the computed value and the correct value.

The place value indicates the multiple of 10 by which the digit is multiplied. The given numbers have the same values in the ones place value, the difference are in the numbers to the right of the decimal point.

The given numbers are;

2.615

2.65

2.7

2.623

The steps to order the numbers from least to greatest;

Add zeros to the shorter decimals such that each number have the same number of digits after the decimal point; 2.615, 2.650, 2.700 2.623

Then

Select the number with the lowest ones; Which gives all the numbers

Then

From the above list, select the number with the lowest tenth, and move them to the left of the list; Which gives the numbers, 2.615, 2.650, 2.623, 2.700

Next

From the above list, select the number with the lowest hundredth, and move them to the left of the list, in increasing order of the hundredth; Which gives the numbers, 2.615, 2.623, 2.650, 2.700

The numbers 2.615, 2.623,2.650, 2.700,  are in the order from least to

greatest.

Hence, Jaiden's error is that Jaiden should have added zeros to each of the shorter decimals to get 2.615, 2.650, 2.700, and 2.623, then he should have compared them using place values.

Complete question:

Jaiden is ordering 2.615, 2.65, 2.7, and 2.623 from least to greatest. Here are his steps: (1) Compare and order 2.7 and 2.65 because they have the fewest digits. (2) Compare each digit of the numbers 2.615 and 2.623. * The units digits are equal. * The tenths digits are equal. * 1 < 2 in the hundredths place so 2.615 < 2.623. (3) Combine the two lists into one: 2.7, 2.65, 2.615, 2.623. Which statement describes Jaiden’s error?

(1) The numbers are listed from greatest to list

(2) The two numbers with the most digits should have been compared first

(3) Zeros should have been added to the numbers to get, 2.615, 2.065, 2.007, and 2.623. Then the numbers should be compared using place value

(4) He should have added zeros to each of the shorter decimals to get 2.615, 2.650, 2.700, and 2.623, then he should have compared them using place values.

The number you would divide by to calculate the mean of 3, 4, 5, and 6 is 4. The mean of 3, 4, 5, and 6 is 4.5.

1. Add all of the numbers together: 3 + 4 + 5 + 6 = 18

2. Count how many numbers there are: 4

3. Divide the sum by the number of numbers: 18 / 4 = 4.5

The mean is a type of average. It is calculated by adding all of the numbers together and then dividing the sum by the number of numbers. In this case, we added 3, 4, 5, and 6 together to get 18. We then divided 18 by the number of numbers (4) to get 4.5, which is the mean of 3, 4, 5, and 6.
