If f(x) = V7x + 31 , find f(0).
Answers
Answer:
f(0) = 31
Step-by-step explanation:
We are given the following function:
[tex]f(x) = \sqrt{7x} + 31[/tex]
f(0).
This is the value of f when [tex]x = 0[/tex]. So
[tex]f(0) = \sqrt{7*0} + 31 = \sqrt{0} + 31 = 0 + 31 = 31[/tex]
So f(0) = 31

C.4,080 cm2
D.2,280 cm2
Answers
Answer:
D. 2,280 cm²
Step-by-step explanation:
Surface area of triangular prism = bh + (S1 + S2 + S3)*L
Where,
b = 24 cm
h = 10 cm
S1 = 26 cm
S2 = 24 cm
S3 = 10 cm
L = 34 cm
Plug in the values
Surface area = 24*10 + (26 + 24 + 10)*34
= 240 + 2,040
= 2,280 cm²

Suppose that there are 5 children in a gymnastics class. One day, they count the number of steps each person takes while walking on their hands until they lose balance and come down. The results are: Ashley (20), Brittany (8), Carol (22), Darla (26), and Erica (24). The mean number of steps these children took while walking on their hands is 20 steps. Identify the population and parameter.
Answers
Answer:
Population = number of children in gymnastic class = 5
Parameter = mean number of steps taken by the 5 children
Step-by-step explanation:
The population could simply be referred to as the total number or set of similar objects or subjects related to a certain study or research. In the scenario described above, the area of interest is a particular gymnastic class, therefore all individuals or children belonging to this particular gymnastic class makes up the population.
Parameter on the other hand are statistical metrics, values or calculations derived from the population figure or information. Here, the mean value of steps obtained from the step counts of the population data is called the parameter.
Population is number of children in gymnastic class = 5.
Parameter is mean number of steps taken by the 5 children.
Given that,
Suppose that there are 5 children in a gymnastics class.
One day, they count the number of steps each person takes while walking on their hands until they lose balance and come down.
The mean number of steps these children took while walking on their hands is 20 steps.
We have to Identify,
The population and parameter.
According to the question,
Parameters are descriptive measures of an entire population. However, their values are usually unknown because it is infeasible to measure an entire population. Because of this, you can take a random sample from the population to obtain parameter estimates.
The population could simply be referred to as the total number or set of similar objects or subjects related to a certain study or research.
The scenario described above, the area of interest is a particular gymnastic class, therefore all individuals or children belonging to this particular gymnastic class makes up the population.
Parameter on the other hand are statistical metrics, values or calculations derived from the population figure or information.
Here, the mean value of steps obtained from the step counts of the population data is called the parameter.
A parameter is a value that describes a characteristic of an entire population, such as the population mean.
The population mean and standard deviation are two common parameters.
Hence, Population = number of children in gymnastic class = 5.
Parameter = mean number of steps taken by the 5 children.

What is a circle?A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.
A cross section is defined as the process where a surface is shown when a straight cut is made by something. We are given when a cone is intersected by a plane horizontally the shape of the cross - section is a circle .
When the cone is intersected vertically by a plane the shape of the cross- section will be a triangle. Hence the shape of the cross section depends according to the cut.

According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. Suppose one Asian adult male is randomly chosen. Let X = height of the individual. a. X ~ __N___(_66____,__2.5___) b. Find the probability that the person is between 65 and 69 inches. Include a sketch of the graph, and write a probability statement.
Answers
Answer:
0.54035
Step-by-step explanation:
Given that :
Mean, m = 66 inches
Standard deviation, s = 2.5 inches
P(65 < X < 69)
P(X < 69) - P(X < 65)
((69 - 66) / 2.5) - ((65 - 66) / 2.5)
P(Z <(3/ 2.5)) - P(Z <(-1 / 2.5))
P(Z < 1.2) - P(Z < - 0.4)
0.88493 - 0.34458

There is a number on each card.

?
The mean of the 4 numbers on Ed's cards is 10
Work out the number on the 4th card.
Answers
Answer:
7
Step-by-step explanation:
Let's call the missing card number "x".
The mean is the sum divided by the number of elements, so we know that:
[tex]\frac{12 + 6 + 15 + x}{4} = 10\\~\\12 + 6 + 15 + x = 40\\33 + x = 40\\x = 7[/tex]
The number on the 4th card is 7 according to the given question when The mean of the 4 numbers on Ed's cards is 10
To work out the number on the 4th card, we can use the information given about the mean of the four numbers.
Mean is calculated by summing all the values and then dividing by the number of values. In this case, the mean is 10 and there are four numbers.
Given:
Mean = 10
Number of cards = 4
To find the sum of the four numbers, we multiply the mean by the number of cards:
Sum of the four numbers = Mean * Number of cards
Sum of the four numbers = 10 * 4
Sum of the four numbers = 40
Now, let's find the number on the 4th card. We subtract the sum of the three known numbers from the sum of the four numbers:
Number on the 4th card = Sum of the four numbers - Sum of the three known numbers
Number on the 4th card = 40 - (12 + 6 + 15)
Number on the 4th card = 40 - 33
Number on the 4th card = 7
Therefore, the number on the 4th card is 7.

Answers
Answer:
50.24
Step-by-step explanation:
The formula for area is pi · r²
But, because usually people want it simplified instead of a ton of decimal numbers following, pi is rounded to 3.14. And the radius in this case is 4. And the ² means squared, so we have to do 4 · 4 to square it.
So, now our formula is 3.14 · 4 · 4 which equals 50.24
