Answer:

0.969

Step-by-step explanation:

use the z-score formula to convert the values.

z = (X - υ) / σ

where X is the test statistic, υ is the mean, σ is the standard deviation.

z = (18 - 31) / 7

= -1.857

area in z-score table (this is area to left of <18) is 0.0314.

P(>18) = 1 - 0.0314 = 0.969

Answer:

BF = 18

Step-by-step explanation:

In triangle BCD, H is the Centroid.

Centroid of a triangle divides the median in the ratio 2 : 1.

Therefore, BH : HF = 2 : 1

Let BH = 2x & HF = x

Since, HF = 6.... (given)

So, x = 6

2x = 2*6 = 12

BH = 12

Now,

BF = BH + HF = 12 + 6

BF = 18

The probability that a resident of this city who is 60 years old will survive until they are 80 will be 0.54 l.

Probability simply means the chance that a particular thing or event will happen. It is the occurence of likely events. It is simply the area of mathematics that deals with the numerical estimates of the chance that an event will occur.

In this case, in the city of exactly 100,000 people, 90% can expect to live to (at least) age 60 and 60% can expect to live to (at least) age 80.

The probability that a resident of this city who is 60 years old will survive until they are 80 will be:

= 90% × 60%

= 0.54

Answer:

The Medicare tax withheld from her paycheck if the tax rate is 1.45% was $1.015.

Step-by-step explanation:

First, you have to determine the amount that Jane earned by multiplying the amount she earns per hour for the number of hours she worked:

$7*10=$70

Then, you need to calculate 1.45% of $70:

$70*1.45%=$1.015

According to this, the answer is that the Medicare tax withheld from her paycheck if the tax rate is 1.45% was $1.015.

As per the function represented by the table, the correct function notation is f(5) = 9.

Given a function represented by a table is shown as follows:

x| 2 | 5 | 9

y| 9 | 14| 5

We can say that the ordered pair given in the bottom row can be written using function notation as f(5) = 9.

Function notation is a method to represent functions, and it is usually used in mathematics to make it easier to work with functions.

It helps to identify the input, the function, and the output of a function.

Using function notation:In function notation, the input is represented by the variable x, and the output is represented by the variable y.

Therefore, we can say that f(x) = y.

Using the table, we can see that when x = 5, y = 14.

So, f(5) = 14 is the correct answer to the given question.

Here, we see that the x and y coordinates are swapped from what we are used to.

The correct function notation is f(5) = 9.

The center of circle is: (-7,4) and Radius is 7 units

or (-4,7) and Radius is 7 units

We have to compare the given equation of circle with standard equation of circle

Given equation is:

Standard equation of circle is:

3rd pic

down below

Here

h and k are coordinates of center of circle

So,

comparing

Hence,

The center of circle is: (-7,4) and Radius is 7 units

Keywords: Circle, radius

Answer:

Step-by-step explanation:

First expand the equation

That's

( x - 4)² + ( y - 7)² = 49

x² - 8x + 16 + y² - 14y + 49 - 49 = 0

x² + y² - 8x - 14y + 16 = 0

Comparing with the general equation of a circle

x² + y² + 2gx + 2fy + c = 0

2g = - 8 2f = - 14

g = - 4 f = - 7 c = 16

Center of a circle is ( - g , - f)

( --4 , --7)

Which is ( 4 , 7)

The radius of the circle is given by

r = √g² + f² - c

Where r is the radius

r = √ (-4)² + (-7)² - 16

= √16 + 49 - 16

= √49

The largest binary code is on 4 bits, the maximum possible number is binary 1111 or 15. And the maximum decimal number that can be represented with 1 byte is 255 or 11111111.

Binary code:

In math, binary code refers a coding system using the binary digits 0 and 1 to represent a letter, digit, or other character in a computer or other electronic device.

Given,

Here we need to find the largest binary code.

Here we know that, for each digit d in a binary number, starting from the rightmost digit, the value in decimal corresponding to this digit is written as,

=> d2ⁿ + d*2ⁿ⁻¹ .... 0, where n is its position.

For, example would be converting 11001:

Here we start from the right

=> 1*2⁰ + 0*2¹ + 0*2² + 1*2³ + 1*2⁴ = 25.

Therefore, if we have 8 bits, the largest number would be 11111111, That has the value of 255, which is the same result as the conversion above (1+2+4+8+16+32+64+128).

Answer:

x = 2

Step-by-step explanation:

Given equation,

→ -6x + 2 = -10

Now we have to,

→ Find the required value of x.

Then the value of x will be,

→ -6x + 2 = -10

Subtract RHS with the number 2:

→ -6x = -10 - 2

→ -6x = -12

Cancel negative sign from both sides:

→ 6x = 12

→ x = 12/6

→ [ x = 2 ]

A statistical analysis is internally valid if option B is correct, meaning that the statistical inferences about causal effects are valid for the population studied. Internal validity refers to the accuracy of conclusions drawn from a study, specifically focusing on causal relationships within the population being analyzed.

Statistical analysis is a method of examining data to identify patterns and trends, which can help researchers make informed decisions. Regression is a technique used to determine the relationship between two or more variables, where one variable (the dependent variable) is affected by one or more other variables (independent variables).

The population refers to the entire group of individuals or objects being studied. In order to have internal validity, the statistical analysis must accurately represent the population's characteristics and the causal relationships between variables.

R² (option A) is a measure of how well the regression model fits the data but doesn't necessarily imply internal validity. Option C, t-statistics, is related to hypothesis testing and helps determine if a relationship between variables is statistically significant. However, having all t-statistics greater than |1.96| doesn't guarantee internal validity.

Lastly, option D states that the population is small (less than 2,000) and can be observed. While having a smaller population might make it easier to gather data, this does not guarantee internal validity.

In summary, internal validity is achieved when the statistical inferences about causal effects are valid for the population studied (option B). It ensures that the conclusions drawn from a study are accurate and represent the true relationships within the population.

A 24U rack is approximately 44.5 inches (113.03 cm) tall.

What is Expression in math ?

An expression is made up of one or more integers or variables, as well as one or more operations.

The "U" unit in a rack height refers to unit of measurement for the height of equipment in a standard 19-inch server rack.

1U is equal to 1.75 inches (4.45 cm)

so, 24U is equal to 24 * 1.75 inches = 42 inches (106.68 cm).

However, in practice, the height of a 24U rack is typically slightly taller to account for the height of the mounting brackets and other hardware.

answer: you would just substitute all of the values you see for b into the equation where there's a b

Answer:

55; 64; 73

Step-by-step explanation:

In the table, they provide a b value. Basically, you plug in the value of b they give you into the expression n = 9b + 19

if b = 4:

n = 9(4) + 19

n = 36 + 19

n = 55

if b = 5:

n = 9(5) + 19

n = 45 + 19

n = 64

if b = 6:

n = 9(6) + 19

n = 54 + 19

n = 73

Check your work with the last numbers in the table. They say the value of n = 82 when b = 7 so try it

if b = 7:

n = 9(7) + 19

n = 63 + 19

n = 82

Work is correct
